To produce the best organic chicken fertilizer from your chicken manure is quite a complex process that has been simplified today, thanks to advanced technology which has hastened and eased it. The process begins with material selection, then composting, crushing and mixing, screening, granularization, drying and cooling, then finally packaging, in that particular order. The details of each step are as follows:
Selection of raw material
Whereas as the word suggests, we’re going for chicken waste, some people opt to throw in some more organic manure like biogas residue, crumpled leaves and so on. This first step involves the collection of all the raw materials and piling them up.
This involves the fermentation of the organic matter into nutrients that are safe to use on plants. It is done by oxygen-consuming bacteria and fungi in the presence of oxygen. This means regular turning is a necessity. It is also crucial to adjust the moisture 50-60 percent, which is attainable by adding wood shavings or sawdust. This addition also helps stabilize the high nitrogen content of chicken manure. The process is easily carried out using a compost turner.
Crushing and mixing.
Crushing is done to produce a uniform fine powder of the resultant compost, now called fertilizer. It is usually done by a vertical mixer to avoid caking. The mixing is done to ensure a homogenous mix and may include the addition of elements to ensure nutrient levels reach a certain threshold.
A rotary screening machine is used to ensure that all caked pieces are broken down as well as sieve out any impurities present. It is done by a cylinder round sifter though there can be two screening machines to further refine the finished product.
The powder is then processed by a machine to form grains or granules. In some cases, a pelletizer is used to turn the organic matter into pellets instead. Any pieces that fail to be properly granulated are usually pre-crushed and re-granulated as well.
Drying and cooling
Drying removes moisture thus increasing the durability of the granules, by avoiding any bacterial attack. The cooling makes the product ready for the final step, which is the packaging.
This final step encloses the granules into bags that can then be stored or distributed to the various retail shops for sale. It is done using automatic packing machines which eliminate the need for sewing machines and so on. finished product packing is also done using packing scales, sack closers, stock bins and so on.
One would ask why fertilizer is the ultimate choice as compared to manure. Simply put, it is durable and of a higher quality. When fertilizer whether organic or inorganic is put in soil, it leads to the activation of inorganic nutrients in the soil which boost plant growth. Granularization and powdering make the fertilizer easy to transport and measure. When looking to commercialize this chicken manure fertilizer, be sure to consider market capacity, availability of raw materials and of course capital. This will guide on knowing the scale of production to adopt.

Farm use of organic fertilizer is key to the development of ecological agriculture. Most of the essential nutrients and elements for plant growth are contained in organic fertilizers, however, it is difficult for plants to use it directly. Composting allows the nutrients to be released, improving soil structure and productivity that make it possible for plants to absorb the nutrients.
Different Types of Materials used in Organic Fertilizers
There are several different types of materials that can be used in a fertilizing production machine to produce organic fertilizer:
• Livestock and poultry waste and manure from cattle, sheep, horses, and rabbits
• Agricultural waste such as soybean meal, cotton meal, and straw
• Industrial wastes such as wine, vinegar, sugar, cassava, and furfural lees
• Urban sewage and river sludge
Organic fertilizing machines are available in small, medium, and large scale sizes.
Types of Organic Fertilizers
We have two types of organic fertilizer production lines available to turn animal manure into fertilizer – organic powder fertilizer and granular fertilizer production line flow. Both will produce high-quality organic fertilizer.
Organic Powder Making Fertilizer Production Line
Organic manure fertilizer powder is one of the simplest fertilizer-making systems compared to a complete production line in a factory. The machine is capable of manufacturing fine powder fertilizer from organic substances.
The organic powder fertilizer production flow line includes the following components:
– Fertilizer compost turner
– Fertilizer granulator
– Fertilizer crusher
– Fertilizer screening machine
– Fertilizer drying and cooling machine
– Cyclone fertilizer dust collector
– Packing scale
– Coating machine
– Fertilizer bagging machine
The powder fertilizer production line is cost-effective as it reduces the amount of manual labor required. The cost can be further reduced by replacing the fertilizer bagging machine with manual labor.
The capacity of the powder fertilizer machine ranges from 1 t/h to 20 t/h depending on your particular requirements.
Granular Organic Fertilizer Production Machine
Granular fertilizer production flow process is more complicated than the powder fertilizer making process. Lately, the pellet fertilizer process has become much more popular around the world. The size and increased weight of the pellets make it easier to handle and use and certain inorganic elements can be added to improve the effectiveness of the fertilizer. Adding these elements to powder fertilizer can cause moisture absorption and agglomeration.
There are three steps involved in the complete granular organic fertilizer making process:
1. Pre-Treating Process – this is the first step in the fertilizing production line that prepares organic compost for agricultural use. The organic fertilizer compost turner component of the machine is used in this phase of the process.
2. Pelletized Organic Fertilizer Process – in the second phase of the process the organic fertilizer granulator is used as well as the drying and cooling machine.
3. Post Processing – in the post-processing phase the fertilizer screening machine is used together with the organic fertilizer polishing machine. Optional fertilizer bagging equipment is also available if required.
In addition, we are able to provide you with a customized organic fertilizer production line flow if that is what your operation requires.
In contrast to wet granulation, which requires the use of a liquid binding agent, dry granulation is the process of turning dry powdery materials into granules using extrusion forces. During the process, the tiny powder particles are forced to adhere to each other due to large compression forces, resulting in larger, multi-particle entities, ie. granules or pellets.
Double roller granulators work be forcing fine powdery materials between two counter-rotating rollers with pitted surfaces. As the powdery material is squeezed between the counter-rotating rollers with pitted surfaces, it is compacted into hundreds of separate, dense granules.
A typically double roller fertilizer granulator will produce granules with diameters ranges from 3.5mm to 10mm one at a time. However, a machine designed for large-scale production can produce dozens of granules at the same time. The granulating ratio of double roller fertilizer granulating machines is over 85%, which makes them very efficient machines for a commercial compound fertilizer production line.
The reason why dry granulating methods are popular is that no-drying processes are needed and the machines can operate at room temperature. The result is lower energy costs and fast granulating for fertilizer manufacturers. It’s not hard to see how double roller fertilizer granulators can offer great ROI rates.
Application And Features Of Double Roller Fertilizer Granulator Machines
1. Fertilizer granules require no drying processes and have 5% moisture content at a maximum.
2. Reliable motor adoption design. No three waste setup. Easy to maintain and stable granulating.
3. Advanced technology and high-grade construction materials ensure no corrosion, easy maintenance and long working life.
4. Versatile machines with wider applications. A truly multifunctional machine.
5. Perfect for producing popular domestic fertilizer formulations such as making ammonium bicarbonate fertilizer, tombarthite fertilizer, ammonium persulfate fertilizer and more.
6. High intensity and uniform fertilizer pellets produced with a high granulating ratio.
7. Can operate at room temperature, so energy costs are considerably reduced.
8. Low noise output during granulating.
There are four main systems that make up a double roller fertilizer granulator: rollet machine rack, transmission systems with connection parts, granulating part, and crushing and separating component. The transmission system consists of a high powered motor that drives a belt pully around reduction gears. The granulating part consists of rotating rollers attached to a driving shaft with specialized bearings and brackets. You can learn more about the other components of a double roller granulating machine by checking out the technical specification sheets of popular models.
The bottom line is that if you are looking to start a large-scale NPK compound fertilizer pellet making business, a double roller granulator would be a great investment. It is one of the best machines for pelletizing large quantities of powdery materials like composted cow manure, poultry manure, etc.
There are many suppliers of dry granulating machines for sale online. Be sure to take your time to research the best suppliers and the best machine models. You don’t want to risk investing in a machine that does not have the output capacity to meet the needs of your fertilizer pellet manufacturing business.
It’s well-known that fertilizer granules are made from cow dung. However, many people have a limited understanding of these kinds of machines and how they operate. It’s important to remember that there are many different machines on the market, and not all of them process cow dung in the same way. If you have questions about processing machines and how they operate, there are several ways for you to get answers.
The Dung Will Go Through Numerous Processes
It typically takes more than a single process to convert dung into granules. While the number of processes varies from plant to plant, it’s not unusual for dung to go through at least three processes before it is fully converted.
The process of turning fresh dung into granules that can be sold takes time. Dung can’t instantly be converted into granules. It will have to go through numerous steps before the process can be completed.
Cow Dung Is Typically Dried
One of the primary steps involved in making granules is the drying process. While some types of fertilizer are still wet, granules are generally dry to the touch. This means that the dung needs to be placed in some sort of dryer.
There are many different types of dryers that can be used when processing cow dung. It’s important to find a dryer that is able to work quickly, as this can be one of the longer steps in the conversion process.
Processing Dung Can Consume A Lot Of Power
Because there are numerous steps involved in the process of converting cattle dung to granules, a great deal of power can be consumed in the process. This can increase the total cost of producing granules.
It’s important to take these kinds of costs into consideration and search for energy-efficient machinery when setting up a fertilizer plant. It may also be worthwhile to find a process that involves fewer steps so that less power will be consumed overall.
There Are Options
Anyone that is interested in operating a fertilizer plant should know that they have options. There are all sorts of ways to produce granules, and you’ll want to look at different options before you make any decisions about what you want to do next.
Having options means that you won’t be locked into one particular system. You’ll be able to evaluate your needs and find a system that is well suited to those needs. You’ll be able to compare and contrast different systems and find something that is a good fit for your plant. Look closely at all of your options so that you can decide how you would like to proceed.
Do you have questions about how cow dung processing machines are able to convert fresh cow dung into fertilizer granules? If this is something that you are curious about, you should utilize the advice above so that you’re able to get the information that you need. Having a clearer understanding of cow processing machines can help you to make an informed decision if you are planning on purchasing a machine like this in the future.
When it comes to fertilizer granulation, there are a number of different machines that you can choose from. This can make the decision a challenge because all machines will appear to offer what you need. To ensure you choose the right granulation machine for your fertilizer making, you need to consider certain factors.
The Size Of The Machine
The first factor to consider is the overall size of the machine. The size of the granulation machine will determine the output that you are able to achieve. Some machines will provide output information by hour and others will have a large annual output amount.
Regardless of the way this is reported, you will need to know what you should look for. The output should match the needs of your production. Some machines will have an output of 10,000 tonnes per year while others offer 100,000 tonnes per year. Of course, it is important to note that the larger the size of the machine, the greater the costs will be. It is helpful for you to find a professional granulation machine supplier for recommendation.
The Granule Shape
The next factor to consider is the shape of the granules you want. There are 4 granule shapes that you can choose from. These are powdery, columnar, spherical and columnar. The machine you choose will impact the shape of the granules you get.
If you choose a flat die extrusion granulator, you will only be able to get cylindrical granules while a rotary drum granulator will only provide granules in the shape of balls. Double roller extrusion granulators will provide cylindrical granules while the pan granulator will produce balls as well. The shape of the granules you need will vary depending on their use.
The Quality Of The Machine
Once you know the size you need and the granule shape, you have to look at the quality of the machine. Granulation machines are not cheap and you need to ensure it will last for a long time. The better the quality of the materials, the longer it will last.
Before you buy the machine, you should find out what materials are used. Ideally, you will want a machine that uses durable metals and does not have plastic components. You should also find out if the machine has passed any quality certifications.
When looking at the quality of the machine, you should also do some research into the fertilizer granulator manufacturer. The more reputable the manufacturer, the better the machine is likely to be. You should also ensure that they have a good reputation for granulation machines and that their reputation has not been built on other machinery.
The After Sales Service
The after sales service you get is also important. You need to ensure that the manufacturer offers you an after sales service and for how long this will last. Any warranties or guarantees will also need to be clear and information provided in writing.
Choosing the right granulation machine for your fertilizer production is important. There are many factors that you need to consider when looking at these machines. You need to ensure they offer the output you need as well as the right granule shape.
A bio fertilizer plant can be an extremely profitable project. The raw materials are free, provided that you have cow, horse or goat manure, home scrap or agricultural waste readily available. Other auxiliary materials are fairly inexpensive, so you’ll have everything you need to start making organic fertilizer for a profit. However, such production lines can secure a nice profit only if you manage to keep the costs under a certain level. Here are a few ideas to help you lower the costs in your bio fertilizer plant project.
The initial cost is very important. As you can easily imagine, you’ll have to spend money on equipment and machines to set up your bio fertilizer plant. You may also need to hire an expert to help you design the plant and acquire all required machines. You’ll have to figure out a method to collect the manure and to prepare it for composting. All these things will trigger expenses you need to be prepared for.
One way to lower the costs is to do some of these initial things yourself. You can read about the different types of machines and about the ideal configuration of a small scale bio fertilizer plant. If you invest time into learning the ropes of this business, you won’t need to pay an expert to help you. Besides, manufacturers of fertilizer making machines will surely tell you everything you need to know to make the right choice of equipment. It’s in their best interest to keep their clients happy, so you can rest assured that you’ll get some advice free of charge. Just make sure you know how to ask the right questions.
Another viable way to lower the cost in your bio fertilizer factory project is to do proper market research before purchasing your machines. Avoid buying everything from the first supplier that comes your way. Try to find out what are your available options and ask at least three different suppliers for price quotes on their machines. Only by comparing their offers you’ll be able to find the best deal possible. Besides, this could be an excellent ground for negotiations, so ensure that you hone your negotiation skills before asking for quotes.
Remember that high quality equipment lasts longer and doesn’t break as often as cheaper machines. You may need a higher upfront investment, but it will be well worth it on longer term, as your plant will operate smoothly and continuously, without stops and without expensive repairs.
Using automation wherever possible is another effective way of keeping your operating costs down. For instance, a self-propelled compost turner is more economical than other devices, because it doesn’t require anything else than close monitoring. You can use this reasoning for all other machines you’ll have to buy. In addition, try to invest in low energy consumption compost machines. They will save you money month after month, so they may pay for themselves within a fairly short time frame. Put all these on paper and take the smartest busienss decisions to keep your costs at bay.
Chicken manure consists of macronutrients nitrogen, potassium, and phosphorous, as well as sulfur, magnesium, and calcium, which are vital for plant growth. However, chicken manure also contains high concentrations of bacteria during its raw form, such as the pathogenic salmonella. That implies that you should avoid applying raw chicken litter to your edible garden. Your growing produce might come into contact with the present bacteria, which can either move within the plant’s cells or stick to the surface.
What’s more, your plants might very well die because of excessive available salts and nitrogen, if you use raw, non-composted chicken manure on your plants. The most suitable way you could dispose of the litter is to first compost it before using it correctly and safely. But how do you do it? You can make chicken fertilizer by composting chicken manure
– Gather Materials
Consider bedding material, such as wood shavings and rice hulls, and keep it in a composting bin. You’ll be looking for around 25% manure and 75% other materials, which could include the earlier-mentioned bedding material, kitchen scraps or plant material, lawn clippings and leaves. You should also have a minimum of 1 cubic foot of material to enable the composting procedure to heat the build-up to an internal temperature of approximately 140 to 160 degrees F, which will destroy the pathogenic bacteria. More information: https://fertilizerplantdesigner.com/chicken-poop-compost/
– Add Water
You’ll be aiming to add enough water such that the pile-up would correspond the texture of a wet sponge. Then, leave it.
– Monitor the Temperature
Using a composting thermometer, that you can buy at a home improvement store or online, monitor the temperature daily, and keep a detailed temperature log that you can refer to. Your aim should be achieving a temperature ranging 140 to 160 degrees F and maintain that specific temperature for approximately three days. Keep in mind that the temperature is the key to killing the salmonella, as well as common bacterial pathogens available in chicken litter. If you fail to obtain that temperature, there will be an increase in the likelihood of pathogen survival for a long period.
As the inside part of your pile is treated, the external isn’t. You should, therefore, repeat the entire process a minimum of two more times to ensure all pile parts have been treated.
For a minimum of 80 days, put the compost you have in a covered pile. The waiting period assists in making sure that the pathogenic bacteria have been destroyed.
In general, make sure to apply compost as close as you can to planting time and apply it 1/2 inch deep to your particular lawn or around 1 and 2 inches deep to your crops. In case you need your compost thoroughly analyzed for macronutrients, including potassium, phosphorous and nitrogen, and salmonella and E.coli levels, you could collect a sample and give it to a private diagnostic lab.
Producing Compost is an ideal and safe fertilizer for any home garden; when processed correctly. Apart from offering nutrients to your plants, the chicken litter provides organic matter to the soil, enhances the water holding capacity, as well as the useful bacteria available in the soil. However, processing it correctly is paramount.
With the federal CAFO (Concentrated Animal Feeding Operations) regulations now in effect, now would be the best time to think about turning manure into fertilizer granules. This will not only create a new source of income, but you will also be complying with the latest government rules.
The Wealth In Manure
While manure is often associated with a bad reputation due to the issues that it poses, many farm owners have now discovered that it also provides a solution. Granulating manure into dry fertilizer products alleviates many of the issues linked to manure, as well as taking advantage of the nutrient content in this waste. More importantly, fertilizer produced from manure contains high levels of micronutrients which are usually not present in inorganic-fertilizer com-pounds.
Granulation of manure (organic waste), into fertilizers can address a number of issues at once:
• Manure piles will not take up space in fields that are required or needed to grow food.
• The nutrient value in manure is no longer going to waste or damaging ecosystems and surrounding water sources.
• Soils can be replenished at appropriate and measurable rates.
The benefits achieved for the surrounding ecosystems and the soil, extend further by offering several advantages for the end-users, some of these include:
• The dry granules are a lot more cost-effective and easier to transport when compared to wet and raw manure.
• The heat from the dryers that are used in granulation processes removes harmful micro-organisms and pathogen, leaving behind nutritious and safe food for the soil and crops.
• The process of granulation reduces odors, which produces dry granules which are just about odor-free.
• The dry granules provide a premium, nutrient-rich product which is easy to sell for profits.
• The dry granules are easy to spread, and more compatible with machinery that is used for different types of agricultural applications.
Items To Consider For Turning Manure Into Fertilizer Granules
If you are interested in buying a plant to turn manure into fertilizer particle, the cost is usually the most important factor to keep in mind. However, there are a number of factors which will influence the overall price of setting up the plant. Here are a few considerations to keep in mind:
• The fertilizer quality. The high-quality fertilizers will require more machinery and processes. If you are looking to achieve a superior end product when it comes to the form, appearance, and quality of the fertilizer, you will need added auxiliary equipment during the production processes. This will mean that the overall costs will be relatively higher.
• Choosing the right machine. When it comes to production processes, there are various machines to choose from. This allows you to select the equipment and machinery within your budget.
Granulate fertilizer offers a cost-effective method to eliminate and recycle waste from animals. The profits that can be achieved from these processes are also highly favorable, meaning that the outlay is quickly recouped from the profits that you will make. To assess the costs of starting your own plant you can request a quote from the different manufacturers that sell these machines.
Composting is a cost-effective way to deal with the massive demand for fertilizers. The advantage of composting is you get organic fertilizers free from chemicals and other harmful elements. But, purchasing chunks of organic compost fertilizer is not a practical idea. That is why it is best to get a powdered version. This helps farmers to spread the fertilizer thoroughly for a better produce. The question is, what is the best equipment that can help to make powdery organic compost fertilizer? To know the answer, you need to understand the process of making compost fertilizers.
Powdered fertilizer production includes two processes: composting and deep processing. In compositing, the microorganisms digest different organic matters and convert them into absorbable nutrients. On the other hand, deep processing involves the production stage of commercial powdered fertilizers.
There are a few types of equipment and machines that you will need to make powdery organic compost fertilizers:
Among all these machines, the ones responsible for grinding and making powdery organic compost are the vertical crusher and rotary screen machine.
Fertilizer crushing equipment
Depending on the type of compost you want, you can choose from a variety of crushers. Some of the most common ones are hammer crusher, semi-wet material crusher, and vertical crusher. Organic composts come in chunks or like cakes from the forklift feeding machine. The crusher will make sure that these chunks grind to a fine powder. Similar to grinding ingredients while making a delicious food recipe. The advanced crushers come with an adjustable crushing degree.
If you do not want a fine powder, you can lower the crushing power of the grinder. This will leave coarse grains of fertilizers instead of fine powder. You can also select the manure fertilizer grinder depending on the amount of organic compost you deal with. Vertical crushers are suitable for low to medium quantities. However, if you have significantly more demand, you can use a hammer. They can handle large scale composting and grinding simultaneously.
Fertilizer screening equipment
Apart from the fertilizer crusher, the screening equipment is also responsible for producing high-quality powdery organic compost fertilizer. The crushed fertilizer passes from the grinder to the screening equipment where the filters remove all types of dust and unwanted particles away. There are two types of screening machines that you can use: vibrating screen machine and rotary screen machine.
These machines range between 1 and 20 t/h. They come with high screening efficiency that helps to produce the best quality powdery organic compost fertilizer. These screening machines can reduce the dust level in the fertilizer so that it meets the quality standards. It is best to purchase screening equipment that has multiple screening facilities. This will only produce premium-quality powdery organic compost fertilizers.
So, if you already have the entire setup except for these two machines, buy them now. Just make sure you note that the output quantity matches with market demands.
When it comes to improving your overall manure management, there have been a series of new and improved technologies which are now being employed within the industry. In essence, these specialised tech solutions are now serving as a way to even successfully reduce the pollution that is created in water ways because of misused manure. However, in order to properly implement these techniques, a series of management issues must be firstly applied. Our article goes into some important points for managing and selling manure.
Only when manure is effectively managed then the benefits of its use can be captured. This just simply means that it will finally be easier to add it to farming systems while ensuring that the water pollution remains reduced or rather controlled. When biological decomposition occurs, a series of by-products are produced and due to the ways that manure is treated or even stored, the by-products can also be controlled. This allows the farmer to create a highly marketable product, as well as manage the nutrients within the manure along with any odors. Here you can know how to manage your organic animal manure better?
Since microorganisms create the potentially profitable waste products, it is necessary to provide the perfect environment for them to thrive. So, when you carefully handle, treat or store your manure in a desired environment, this encourages the microorganisms to produce by-products which are beneficial to you. Additionally, farmers can use biological manipulation to create the perfect by-product according to their market.
If manure is mixed with a material that is rich in carbon along with enough air, the manure can easily be converted into compost; in a case where all the air has been eliminated and heat is added, you’ll be able to create biogas, as well as a stable effluent. However, biologically manipulating your manure is quite a challenge when it comes to the environment and most of the times the type of animal as well as the feed that they are fed along with a management system all play a huge role in the microbial activities that occur. Additionally, these activities are greatly affected by the solids content.
Those that have a higher solids content are ideal for undergoing aerobic activity. And if you’re used to adding bedding as well as water or even waste feed, this will also affect the microbial activity. Depending on the pH values associated, this can also affect those that participate in creating methane. And as we’ve said before, the food intake also plays a huge role in management since higher protein diets create a pretty intense odor. Making animal manure into organic fertilizers is not only a good way to manage these manure, but also can bring you much profits by selling them.
When it comes to selling, one of the most recommended methods for selling is to simply fill in sizable bags and sell to farmers. You’ll simply need to collect the poop when it is fresh and compost these animal waste in order for your manure to form. And they even generate a pretty decent profit depending on the animal the manure came from. However, if you want to take the markets by storm, you’ll also need to put a little effort into how you advertise your product; don’t forget to be creative.
As we conclude we have just discussed some tips for managing your manure. And we have also given some tips on how to generate a profit for yourself. Remember, you should never apply fresh manure to fruits or vegetables that are eaten raw since you can generate an E. coli outbreak!

As we’ve realized the damage food that’s not so green can do, many of us are turning to organic produce and animal products. It’s created a new farming industry that’s taking over the shelves at most grocery stores. Few consumers think about all the products that go into making these farms possible. There are many companies that help put these foods on the market besides the products themselves. The farms and their suppliers have to work hand in hand to aid in the production of clean food that does the least harm to the environment as possible.
There are many chemicals added to fertilizers that are not specified for organic farms. This problem creates a need for organic farmers to find a supplier elsewhere. Typically, organic fertilizer plants are small and often family run. They supply fertilizer that’s both clean and environmentally friendly. These organic plants require machinery to keep them running smoothly just like their non-organic counterparts. Organic fertilizer producers may use more compost, ect; however, they still need the same organic fertilizer process equipment to process the different ingredients put in organic fertilizers. Here are some that will probably be needed.
Most organic fertilizer plants often spread their product for the farm who they are supplying it to. Some farms also have their own plant. A fertilizer spreader helps to distribute the organic fertilizer once it has gone through complete processing. It’s what helps spread it over the farm land so it can help aid the plants as they grow. This piece of equipment is typically hooked up to tractor, or some other type of vehicle, and pushed through the plots so it can do its function.
A tool bar helps to supply the plant with the ability to spread fertilizer over a wider stretch of land. This helps the fertilizer spread at a quicker rate; thus, making the process much more efficient. The faster the work can be done, the more appealing the plant will be.
Tanks may need to be used to transport compost and other material to and from the plant. Small ones can be bought for quite cheaper than the type you’ll see halling oil on the road. Typically, these tanks need to be attached to a truck so that they can be dragged on the road. This attachment can also be an efficient way to bring fertilizer to the farm once it is ready to be fertilized.
-A Fertilizer Tender
Some aren’t using spreaders to distribute fertilizers. Tenders are also another option for this task. These organic fertilizer machines can take a larger beating and last longer than a traditional spreader. They have a rear discharge. This makes spreading the material easier and allows the machine to last longer.
Organic Is The Future
Non-organic farms have created a lot of problems. Bees are dying from the toxins when they try to pollinate. The chemicals used in traditional farms have been linked to cancer. Are organic options dirtier since they don’t have chemical protection? No, just wash off the produce before you eat.
Compost is nothing else than recycled organic matter that’s very rich in nutrients, and therefore a very good soil conditioner. While it costs almost nothing to make compost, you’ll need raw matter and a special machine. There are many things you can use as raw matter, the most common being sawdust pellets, fruit and vegetable scraps, coffee grounds, chicken manure, dead leaves, grass clippings, as well as any other kind of kitchen and garden waste.
Choosing the right compost making machine depends on several factors such as the raw materials you’re going to use, the type of area you live in, and your willingness to turn the compost manually. In case you want to make compost to sell it to third parties, you’ll need a different type of equipment than the average homeowner wanting to compost their waste.
First of all, you have to determine the volume of matter you want to process per day. Compost machines for commercial and industrial purposes can process from 25 kg per day to 2 tonnes per day. As this is quite a wide range, you have to narrow it down by determining your actual needs. Always allow some room for growth, should your business develop faster than expected. It wouldn’t be too nice to outgrow your equipment within the first year of activity.
The productivity rate is another thing to keep in mind when shopping around for the best machine to make compost. If you need all the speed you can get, you’d better try to purchase a fully automatic machine. In case productivity doesn’t matter as much, you may want to choose a semi-automatic machine instead.
Whatever your choice, make sure that you pick a machine featuring a powerful inbuilt shredder with solid blades, in order to process even the most difficult matter. Always check that the power of the motor matches the capacity of the shredder. In fact, you’ll only need a shredder if you intend to process hard material food waste such as bones. If not, you can save a lot of money by choosing a machine without shredder.
A good machine should also have a mixing chamber, power heaters, a gas exhaler and a liquid fertilizer squeezer. The parts of the machine that come into contact with organic matter have to be made from stainless steel. This will prevent them from rust and will extend the useful life of your machine.
Since composting in not a mechanical process, you should ask all manufacturers of such equipment for their compost quality certificate. This is the only method to make sure you’re going to produce high-quality compost.
As such machines aren’t cheap, you shouldn’t buy yours from the first supplier you encounter. Always seek for at least three quotes from different manufacturers. In addition, check out the work experience and the client references of all companies on your shortlist. Even though such machines should come with a good warranty, it’s usually better to make the purchase from a reputable manufacturer with an effective customer service department.
Express delivery, also known as express delivery or express delivery, refers to a new mode of transportation in which logistics enterprises (including freight forwarders) deliver documents or parcels entrusted by users quickly and safely from the sender’s door to the recipient’s door (hand delivery) through their own independent network or through joint venture cooperation (i.e. networking).
Express delivery can be divided into broad sense and narrow sense. In the broad sense, express delivery refers to the delivery of any goods (including bulk cargo); in the narrow sense, express delivery refers to the urgent delivery service of business documents and small pieces. The object of this textbook research and analysis is mainly the express industry in a narrow sense. According to the standard of service, express delivery generally refers to express delivery service completed within 48 hours. From the definition of express delivery, the following three characteristics of express delivery can be summarized:
From the economic category, express delivery is a branch of the logistics industry, and the research of express delivery belongs to the category of logistics.

From the nature of operation, express delivery is a new service trade with high added value.
Food refers to substances that can meet the normal physiological and biochemical energy needs of the body and extend the normal life span. For the human body, the substance that can meet the needs of normal life activities and prolong life is called food.
Food is usually composed of carbohydrates, fats, proteins and water, which can provide nutrition or pleasure for human beings or organisms by eating or drinking. Food may come from plants, animals or other organisms, such as fungi, or fermented products such as alcohol. Human beings obtain food in many different ways, such as collecting, farming, animal husbandry, hunting, fishing and hunting.
It is generally believed that the digestible substance for human or animal consumption is called food. According to the definition of the experts, the food refers to the substance that can meet the normal physiological and biochemical needs of the body and extend the normal life span. For the human body, the substance that can meet the needs of normal life activities and prolong life is called food.
General food definition: refers to the intoxicated substances that can be eaten and digested and absorbed to form the energy needed by the body to supply activities or regulate physiological functions.
The emergence of agriculture is the origin of human civilization. Previously, people depended on hunting and gathering for food, and their lives depended on how much wild plants and animals provided. As ancestors around the world have gradually observed and familiarized themselves with the growth laws of some plants and gradually learned how to cultivate crops on the basis of collecting economy and long-term living practice. Due to regional economic development differences, there are three major early farming centers in the world, West Asia, East Asia and Central and South America. Zagros Mountains in West Asia, southern Asia Minor Peninsula, Jordan, Palestine and Lebanon along the Eastern Mediterranean are the earliest agricultural origins in the world. They are also the origins of barley, wheat and lentils. Rice was cultivated in ancient India around 4500 B.C. and beans were planted in northern Thailand around 7000 B.C. Categories, gourds, cucumber crops, Mexico, Peru and Bolivia in Central and South America are the origin of maize, beans, potatoes and other crops.
Ancient Egyptians mainly ate soybeans, lentils, garlic, radish, cabbage, cucumber and lettuce. The fruits they eat are: dates, figs, grapes, pomegranates and various melons, etc.
The emergence of agriculture and domestication of livestock meet people’s needs for food. Crop cultivation and animal breeding mean that human beings begin to replace wild food provided by nature with food produced by themselves, thus ending hunting and collecting life and creating a new era.
If the relatively primitive stage of the agricultural era is the origin of civilization, then the transformation of wild food into domesticated food is the beginning of food civilization. Civilization is the result of mankind’s response to natural challenges. The rise of agriculture and animal husbandry is the turning point for mankind to finally get rid of barbarism and move towards civilization. Crop cultivation and animal breeding were originally designed to have a certain source of food and live a stable life. Through their own production activities, human beings continuously optimize crop and animal species to supply and meet the daily needs of human activity energy. It includes vegetables, fruits and meat. Vegetables generally refer to the different parts of a plant, which can be cooked and cooked into food, and other plants (mostly herbal plants) besides grain. They can be divided into leafy vegetables, melons, beans and rhizomes. Fruit refers to the plant organs with seeds in a plant or the fruits of some plants with more water content for food. There are fresh fruits, nuts, dried fruits and so on; commonly used for family or guests. Meat and meat refer to livestock (pigs, cattle, sheep, etc.), poultry meat (chicken, duck, goose, etc.), aquatic products, fish, etc., which are subcutaneous tissues and muscles of animals, including edible parts of any animal used for food, containing high protein and fat, and a large number of calories. (Summary of Food Nutrition by Xia Shengqing et al.)
Taking the water system as a whole, according to the geographical distribution of towns and industrial and mining enterprises along the coast of the water system, as well as the self-purification capacity, pollution capacity and pollution status of the water system, comprehensive prevention and control measures are taken to prevent and control water pollution. It includes various engineering technology means and management measures, which have the characteristics of integrity, comprehensiveness and regionality.
Comprehensive prevention and control of water pollution is a comprehensive application of various measures to prevent and control water pollution. Prevention and control measures involve two types of engineering and non-engineering, mainly:
(1) Reducing the discharge of wastewater and pollutants, including saving production wastewater, stipulating water quota, improving production technology and management system, increasing the reuse rate of wastewater, adopting new technology without pollution or less pollution, and formulating material quota, etc. For water-deficient cities and industrial and mining areas, regional recycling water and wastewater reuse systems should be developed.
(2) Developing regional water pollution prevention and control systems, including formulating urban water pollution prevention and control plans, river basin water pollution prevention and control management plans, implementing the total amount control system of water pollutant discharge, developing sewage after proper manual treatment for irrigation farmland and reuse for industry, establishing sewage reservoirs without polluting groundwater, and low water. Periodic storage of sewage reduces sewage discharge load and conducts controlled dilution during flood period.
(3) Develop wastewater treatment technologies with high efficiency and low energy consumption to treat wastewater.
Comprehensive prevention and control of pollution refers to the comprehensive use of various measures to prevent and control water environmental pollution from the whole point of view. It is very necessary to implement comprehensive prevention and control of water pollution, because China is a country with relatively scarce water resources, and there are two manifestations: one is resource-based water shortage, the other is water-quality-based water shortage. For a long time, the purification treatment of sewage outlet based on point source control can not effectively solve the problem of water pollution. Comprehensive prevention and control of water pollution must be carried out from the overall point of view of the region and water system in order to fundamentally control water pollution and solve the problem of water shortage caused by water quality.
Why do this
The necessity and urgency of comprehensive prevention and control of water pollution are embodied in two aspects: first, the contradiction between water resources shortage and unbalanced supply and demand is prominent, and the serious pollution of water environment makes this contradiction more prominent and urgently needs to be solved;
Why is it so urgent?
Secondly, the purification treatment of sewage outlets based on point source control can not effectively solve the problem of water pollution. Comprehensive prevention and control of water pollution must be carried out from the whole region or water system, and the tail control of point source control should be transferred to the source control in order to control water pollution fundamentally.
The basic principle of sewage prevention and control is the combination of prevention, treatment and management.
Through effective control and preventive measures, the amount of pollutants discharged by pollution sources can be reduced to the minimum.
(1) For industrial pollution sources, the most effective control method is to promote cleaner production. Cleaner production refers to the advanced production technology with the smallest utilization of resources and energy and the least pollution emission. The main technical routes adopted in cleaner production include: reforming raw material selection and product design, replacing toxic and harmful raw materials and products with non-toxic and harmless raw materials and products; reforming production process to reduce consumption of raw materials, water and energy; adopting recycling water system to reduce wastewater discharge; and recycling the usefulness of wastewater. Composition, reduce the concentration of wastewater, etc. Cleaner production advocates life cycle analysis and management of products rather than end-treatment.
(2) For domestic pollution sources, effective measures can be taken to reduce their emissions. Such as promoting the use of water-saving appliances, improving people’s awareness of water-saving, reducing water consumption, thereby reducing domestic sewage discharge.
(3) For agricultural pollution sources, in order to effectively control non-point pollution sources, we must start from “prevention”. Promoting scientific fertilization and rational use of pesticides in farmland can greatly reduce the residual fertilizers and pesticides in farmland, thereby reducing the amount of nitrogen, phosphorus and pesticides contained in farmland runoff.
Through various measures to control pollution sources and polluted water bodies, the pollution sources can achieve “standard discharge” and the water environment can achieve the corresponding water quality function.
It is very difficult or almost impossible for pollution sources to achieve zero discharge. Therefore, it is necessary to properly treat polluted (waste) water to ensure that the discharge standards set by the state or local authorities are met before it is discharged into the water body. Great attention should be paid to the relationship between industrial wastewater treatment and municipal wastewater treatment. For industrial wastewater containing acid, alkali, toxic and harmful substances, heavy metals or other special pollutants, local treatment should be carried out in the plant to meet the discharge standards to the water body or the water quality standards to the urban sewer. Those industrial wastewater similar in nature to municipal domestic sewage can be treated together with municipal sewage as a priority. It is not only unnecessary but also uneconomical to set up sewage treatment facilities separately. The design of urban sewage collection system and treatment plant should not only consider the need of water pollution prevention, but also the need to alleviate the contradiction of water resources. In areas where water resources are scarce, the treated municipal wastewater can be reused for agriculture, industry or municipal administration and become stable water resources. In order to meet the needs of wastewater reuse, its collection system and treatment plant should not be too centralized, but should be close to the reuse target.
In addition, according to the characteristics of water pollution, we should actively take physical, chemical, biological engineering and other means to control pollution, so that the deteriorated aquatic ecosystem can be gradually restored.
Strengthen the supervision and management of pollution sources, water bodies and water treatment facilities in order to promote treatment. Pipe also plays an important role in water pollution control. Scientific management includes regular monitoring and inspection of pollution sources, water treatment facilities and sewage treatment plants, and regular monitoring of water environmental quality to provide basis and information for environmental management.
Functional zoning of water environment is the basis for comprehensive prevention and control of water pollution
According to the current functions of water environment and the needs of economic and social development, the functional zoning of water environment is based on surface water environmental quality standards, which is the basis of water source protection and water pollution control. For example, the surface water environmental quality standard divides the water area control functions into five categories: Class I is mainly applicable to source water and national nature reserves; Class II is mainly applicable to primary protection areas of centralized drinking water sources, precious fish protection areas, fish and shrimp spawning grounds; Class III is mainly applicable to centralized drinking water sources II. Class IV is mainly suitable for general industrial water use and recreational water areas where human body does not contact directly; Class V is mainly suitable for agricultural water use areas and waters where general landscape requires.
Principles and methods
The principles of division are as follows: priority protection of centralized drinking water source areas; water body should not reduce its current use function, taking into account planning function; water areas with multiple functions should be classified according to the highest function; professional water standard requirements should be considered as a whole; consideration should be given to each other between upstream and downstream areas, with due consideration to potential functional requirements; and rational use of water body itself. Net capacity and environmental capacity; Consider the combination of land industrial rational layout; Consider the impact on underground drinking water sources; Practical and feasible, easy to manage.
Functional zoning method: according to the principle of adapting measures to local conditions and seeking truth from facts, according to actual measurement, empirical analysis and administrative decision-making.
Controlling pollution and protecting water sources according to functional areas.
(i) The level of protection shall be defined according to the functions of the waters and the requirements for water pollution control shall be put forward. For example, special protected waters refer to the first and second categories of national Surface Water Environmental Quality Standards (GB3838-2002). No new sewage outlets shall be built for such waters. Existing sewage discharge units shall be strictly controlled by local environmental departments in order to ensure that the water quality of accepted waters meets the water quality standards for specified purposes; and key protected waters shall be protected. It refers to the third class waters stipulated by GB3838-2002, and the first class discharge standards stipulated in the Comprehensive Sewage Discharge Standard (GB8978-1996) are applied to the sewage discharged into the waters.
(ii) The total amount control shall be implemented according to the functional areas. The so-called total amount control refers to the maximum allowable emission of some kind of pollution in order to maintain the environmental target value of an environmental functional area. Therefore, water environmental functional zoning is the basis for implementing total water pollution control.
Formulating comprehensive prevention and control plan of water pollution
Main contents and working steps
(i) Based on the investigation and evaluation of water environment, the main problems of water environment are analyzed and determined.
(ii) Division of water pollution control units. According to the analysis conclusion of water environment problems, considering the administrative division, water area characteristics and pollution source distribution characteristics, the source area and receiving water area are divided into water pollution control units.
(iii) Put forward environmental objectives and demonstrate accessibility. At the Fourth Session of the National People’s Congress, the strategic goal of environmental protection across the century was clearly put forward, which is the basis for the goal of comprehensive prevention and control of water pollution. Environmental objectives should include the total amount control objectives of major pollutants and the specific objectives of various sub-items of comprehensive water environment improvement. It is necessary to demonstrate the accessibility of environmental objectives.
(iv) Determine the amount of major pollutant reduction and the proportion of reduction allocation.
(v) To formulate a comprehensive water pollution prevention and control plan and implementation plan.
(vi) Support and guarantee for the implementation of the plan. Including: analysis of sources of funds, formulation of annual plans, implementation of pollutant discharge declaration and registration and pollutant discharge permit system proposals, as well as the necessary technical support.
Several principles that must be adhered to in formulating comprehensive water pollution prevention and control plan
(i) Focusing on economic construction is conducive to the coordinated development of economy and environment.
(ii) Take rational development and utilization of water resources as the core, focusing on the whole process control. By changing the mode of economic growth and promoting cleaner production, pollution can be eliminated in the process of economic reproduction.
(iii) Overall planning, highlighting key points, adapting measures to local conditions and stressing practical results.
(iv) adhering to the principle of comprehensive improvement. Systematic analysis of the planning scheme is needed to achieve overall optimization.
Emission permit system, transition from concentration control to total quantity control
Practice has proved that in carrying out this system, we must follow the following five requirements in the light of China’s current technological level and management system.
(1) Determine the total amount control target from the actual point of view. When it is difficult to determine the environmental capacity of the receiving water body for discharging pollutants, according to the principle of the total amount control plan put forward by the State Environmental Protection Administration in December 1995, the total amount of discharged major water pollutants in 1995 can be regarded as the target total amount, and the proportion of reduction can be determined according to the actual technical and economic level of the region, and allocated to the main body. Pollution sources.
(2) Choose the target of issuing certificates. The main target of issuing permits is the large polluters in the region. A city can catch more than a dozen or dozens of households. It is necessary to select the key control points through investigation and evaluation of pollution sources. For example, Anyang City put forward that we should do a good job of 2, 5 and 8, and control 8 and 9, that is, we should catch 20, 50 and 80 large polluters in batches, and control 70%, 80% and 90% of the city’s water pollution load.
- Control the total amount of sewage. Measure according to local conditions and control the total amount of sewage.
- Strengthen environmental supervision and management after issuance of certificates.
- Pay attention to practical experience and constantly improve the level. In order to implement the sewage discharge permit system, we should first carry out pilot projects, sum up experience and gradually popularize it.
- But we should also pay attention to the new problems in the process of implementation, such as the paid transfer of pollutant discharge indicators and the trading of pollutant discharge rights.
- Comprehensive Prevention and Control of Water Pollution in Township Enterprises
- The discharge of industrial wastewater from township enterprises was only 3.9 billion tons in 1997.
Housing provident fund refers to the long-term housing savings deposited by state organs and institutions, state-owned enterprises, urban collective enterprises, foreign-invested enterprises, private enterprises in cities and towns, other urban enterprises and institutions, private non-enterprise units, social organizations and their working staff on an equal basis.
In 2011, the Ministry of Housing and Urban-Rural Construction is jointly working with various departments to study and revise the Regulations on the Management of Housing Provident Fund, and to liberalize the provisions on individual withdrawal of provident fund for housing rent payment. In 2013, some cities introduced measures to allow workers suffering from major diseases or their immediate relatives to withdraw provident fund for emergency relief.
In 2014, the three departments issued a document to cancel the housing provident fund personal housing loan insurance, notarization, new housing evaluation and compulsory institutional guarantee and other fee items, so as to alleviate the burden of loan workers.
In 2015, the Regulations on the Management of Housing Provident Fund (revised draft for examination) intends to stipulate that the deposit ratio of workers and units of housing provident fund shall not be less than 5% or more than 12%. From February 21, 2016, the interest rate of employees’housing provident fund account deposits has been adjusted to the benchmark interest rate of one-year fixed deposits. The interest rate after the increase is 1.50%.
From July 1, 2017, all the national housing provident fund management centers will handle the transfer and continuation of housing provident fund in different places through the platform according to the requirements of the “Operation Rules for the Transfer and Continuation of National Housing Provident Fund in different places” issued by the Ministry of Housing and Construction. All national housing provident fund management centers will “network” through a unified platform for the transfer of housing provident fund business in different places. According to incomplete statistics, more than 20 cities, such as Beijing, Shanghai, Fuzhou and Guangzhou, have access to the transfer platform of the National Housing Provident Fund. On May 15, 2018, the Beijing Housing Provident Fund Management Center issued the Notice on the Cancellation of Copies of Identity Certificates as Requirements for the Collection of Housing Provident Fund and the Processing of Loan Business.
Housing accumulation fund refers to the long-term housing reserve deposited by state organs, state-owned enterprises, urban collective enterprises, foreign-invested enterprises, private enterprises in cities and towns and other urban enterprises, institutions, private non-enterprise units, social organizations and their employees.
The definition of housing provident fund includes the following five aspects:
(1) Housing provident fund is only established in cities and towns, but not in rural areas.
(2) Only on-the-job workers can establish the housing provident fund system. Urban residents without jobs and retired workers do not implement the housing accumulation fund system.
(3) Housing provident fund consists of two parts, one part is deposited by the unit where the staff and workers work, the other part is deposited by the individual staff and workers. The personal deposit of employees shall be withheld by the unit and deposited into the individual account of housing accumulation fund together with the deposit of the unit.
(4) The long-term nature of housing provident fund deposit. Once the housing provident fund system has been established, the staff and workers must pay in accordance with the regulations uninterruptedly during their working period. Except for the retirement of the staff and workers or other circumstances stipulated in the Regulations on the Administration of the Housing Provident Fund, they may not suspend or interrupt it. It embodies the stability, unity, standardization and mandatory of housing provident fund.
(5) Housing provident fund is the personal housing reserve fund which is specially used for housing consumption expenditure stored by workers according to regulations. It has two characteristics:
First, the accumulation, that is, housing provident fund is not an integral part of workers’wages, not in the form of cash, and must be deposited in the housing provident fund management center in the entrusted bank to open a special account management.
Second, the special purpose of housing provident fund, the storage period can only be used for purchasing, building, overhauling self-housing, or paying rent. Employees can withdraw the housing provident fund in their accounts only when they retire, die, lose their working ability completely and terminate their labor relations with the unit or move out of their original residence city.
According to China’s regulations, enterprises should deposit housing provident fund for employees, regardless of state-owned enterprises and private enterprises.
The part of housing provident fund paid by enterprises and institutions does not belong to the attributes of total wages, but belongs to the expenditure of the nature of enterprise cost and expense. According to the Notice of the State Administration of Taxation on Deduction of Enterprise Wages and Salaries and Workers’Welfare Expenses (State Tax Letter 3), the term “total salaries and salaries” referred to in Articles 40, 41 and 42 of the Implementation Regulations of the Enterprise Income Tax Law of the People’s Republic of China refers to enterprises in accordance with document No. 3 of the State Tax Letter  Article 1 stipulates the total wages and salaries actually paid, excluding the social insurance premiums and housing provident fund such as the employee welfare premiums, the employee education funds, the trade union funds, the old-age insurance premiums, medical insurance premiums, unemployment insurance premiums, industrial injury insurance premiums and maternity insurance premiums borne by enterprises.
(1) Guarantee, the establishment of the staff housing accumulation fund system, for the staff to solve housing problems faster and better provide security;
(2) Mutual assistance, the establishment of housing provident fund system can effectively establish and form a mechanism and channels for housing workers to help workers without housing, and housing provident fund in terms of funds to help workers without housing, reflecting the mutual assistance of housing provident fund for workers;
(3) For a long period of time, every working worker in a town must pay the individual housing accumulation fund from the date of taking part in the work to the time of retirement or termination of labor relations; the unit where the worker works should also pay the housing accumulation fund for the worker’s subsidy according to the regulations.
(1) Generality, urban employees, regardless of the nature of their work units, family income and whether they have housing, must deposit housing accumulation fund in accordance with the provisions of the Regulations;
(2) Compulsory (policy nature). If a unit fails to register the deposit of the housing accumulation fund or to set up an account of the housing accumulation fund for its employees, the management center of the housing accumulation fund has the power to order it to do so within a time limit. If it fails to do so within the time limit, it may be punished in accordance with the relevant provisions of the Regulations and may apply to the people’s court. Enforcement;
(3) Welfare, apart from the housing provident fund deposited by employees, units should also pay a certain amount of money for employees, and the interest rate of housing provident fund loans is lower than that of commercial loans;
(4) Returnability, the retirement of employees, or the complete loss of labor capacity and termination of labor relations with the unit, the removal of household registration or outbound settlement, etc., the housing provident fund deposited will be returned to the individual employees.
It refers to the state in which personal casualties or property losses can be controlled at an acceptable level in the course of traffic activities. Traffic safety means that the possibility of loss to people or things is acceptable; if this possibility exceeds the acceptable level, it is unsafe. As a dynamic open system, the safety of road traffic system is not only restricted by internal factors of the system, but also disturbed by external environment of the system. It is closely related to human, vehicle and road environment. Any unreliable, unbalanced and unstable factors in the system may lead to conflicts and contradictions, resulting in unsafe factors or unsafe states.
(1) Traffic safety is a state under certain dangerous conditions, and it is not absolutely free from traffic accidents.
(2) Traffic safety is not an instantaneous result, but a description of the process or state of the traffic system in a certain period or stage.
(3) Traffic safety is relative and absolute traffic safety does not exist.
(4) For different periods and regions, the acceptable level of loss is different, so the criteria for measuring the safety of the transportation system are different.
Raising the level of road traffic safety is a matter of great benefit to the country and the people. Many experts and scholars have carried out extensive and in-depth research in this area. Traffic accident prevention is one of the main tasks of traffic safety and an important part of traffic engineering research. From the point of view of traffic engineering, it is considered that the prevention of traffic accidents should start from three aspects: laws and regulations, education and engineering, and from the point of view of people, vehicles, roads and environment, which constitute the four elements of road traffic, it is also considered that the prevention of traffic accidents should start from these four elements.
Improving Transportation Legal System
Strengthening the construction of road traffic safety laws and regulations system is a direct and effective measure to improve the overall level of road traffic safety. At present, the content of our country’s road traffic safety regulation system has been covered in a number of different laws, regulations and other traffic management normative documents, and it plays an active and important role in our country’s road traffic operation practice. With the development of the times, the legal system should be amended and adjusted accordingly.
Strengthen Traffic Safety Education
(1) Carry out traffic safety propaganda
Traffic safety propaganda is an important way to publicize and educate the masses. In carrying out propaganda activities, we should attach importance to achieving practical results and link traffic safety with everyone’s vital interests so as to arouse people’s attention to traffic safety. We should adopt propaganda forms popular with the masses, incorporate them in people’s daily work and life, and in cultural entertainment. At the same time, propaganda activities must mobilize the strength of society to the greatest extent possible, and strive for the depth and breadth of propaganda to ensure the quality of propaganda.
(2) Strengthen traffic safety education
Traffic safety education, like other cultural knowledge, should be carried out systematically from the early childhood. Before high school, every stage of education was listed as a compulsory course, which enabled students to establish the concept of traffic legal system, traffic safety, traffic ethics and safety prevailing concepts from the beginning of education. To educate the society, we should adopt different ways and methods according to different objects, and carry out targeted education.
Improve vehicle safety performance and maintain good vehicle condition
To improve the safety performance of vehicles, we should take active safety measures and passive safety measures.
(1) Active safety measures
1) Improve side and front vision, install reversing lights and alarms to prevent traffic accidents caused by blind areas.
2) Improve the perspective performance of windowpanes to prevent traffic accidents caused by rain, snow and frost.
3) Take anti-glare measures to improve the illumination of headlamp in order to prevent traffic accidents caused by glare and insufficient illumination of headlamp.
4) In terms of power performance, the overtaking acceleration capability should be improved and the drive anti-skid system (TCS) should be installed.
5) In the aspect of stability, we should improve the stability and portability of operation, such as installing electronic stabilization program (ESP).
6) In braking aspect, the auxiliary braking system, ABS anti-lock braking system, retarder and braking system fault alarm system are installed to improve the anti-skid performance of tires, so as to ensure safety.
7) In terms of accident prevention measures, we should also improve the recognition performance of vehicles, including rear, signs and driving directions, in order to prevent accidents.
8) Active anti-collision warning system is adopted. When the vehicle encounters danger, the driver can be reminded in time. If the driver fails to take measures in time because of his errors, the system can automatically take measures to avoid danger (such as deceleration, bypass, etc.).
(2) Passive safety measures
1) In-car measures
In-car measures mainly include increasing occupant space as much as possible, i.e. the strength of the car body, in order to reduce the deformation of the collision, using toughened glass or partition glass to reduce the injury of the occupant caused by the accident, enlarging the area of the steering wheel to make it elastic, and making the switches, knobs and handles inside the car as round as possible. Sliding and soft; door and roof have enough strength to protect the safety of passengers and facilitate rescue. In addition, fire prevention performance, safety belt and airbag play an important role in occupant safety protection.
2) Outside measures
Extravehicular measures mainly refer to minimizing injuries when crashing bicycles and pedestrians, such as bumpers should be as smooth and flexible as possible, movable rearview mirrors and fenders, and protective nets connected with trailers, etc., which will have certain effects on the protection of the weak traffic.
Strengthen the Construction of Road and Traffic Safety Facilities
(1) Improving road conditions
Considering from the aspect of road alignment design, we should strictly follow the horizontal and vertical curves of the designed road to make the curves and ramps conform to the technical standards of highway engineering. The safety of various alignment combinations should be fully considered.
(2) Improving road safety facilities
Road safety facilities mainly include partition belts, safety fences, traffic signs, markings, sight guidance facilities and anti-glare facilities. For urban traffic, pedestrian overpasses, underground passages, traffic safety islands, etc.
(3) Implementing traffic control
Traffic control can be divided into traffic signal control and traffic regulation control. Traffic signal control refers to the establishment of traffic lights at road entrances and intersections to reasonably control the driving of vehicles. Traffic regulation control includes setting up one-way traffic section, turning lane, bus lane, etc.
(4) Establishment of Traffic Information System
Traffic information is also known as traffic information. In order to ensure the safety and rapidity of vehicles traveling on automobile lanes or urban trunk roads, public security and management departments should report traffic congestion, weather, road ahead or temporary traffic control to drivers in time so that drivers can change their countermeasures in time.
(5) Establishing Emergency Rescue System for Accidents
The monitoring and forecasting system estimates possible accident areas according to abnormal weather conditions, adopts information collection and liaison system, and assigns special personnel to monitor and make preparations. When an accident occurs, advanced communication equipment and means should be used to quickly and reliably contact the relevant departments to deal with the accident in a timely and effective manner so as to ensure road safety and smoothness.
(6) Improving the Road Traffic Environment
The improvement of road traffic environment mainly includes two aspects: on the one hand, improving road environment, making drivers have good driving sight distance and constantly changing visual effect, improving the monotonous environment which makes drivers tired and irritable; on the other hand, improving traffic flow environment, keeping good density as far as possible, and avoiding as possible. No mixed traffic flow.

His people sent a polar bear to save their way of life to find itself driving an ice-cream truck around the suburbs, with the aim of reversing global warming, one ice-cream at a time.
Polar Sam Episode #4
The village in the box hit the street.
EPISODE #4 (Previously…… Sun Sam was pushing out a village in a box; he pulled all his ideas aside to concentrate on the task at hand and cheerfully announced them to his small but completely fascinated audience. “This is performance time!”
The equally lively village scene is located in the box container outside the village, full of the entire side of the Polar Sam truck.
“Well,” Sam said, “how do you live? Suburban residents can become………………………………………………………………………………………… “The boys cheered. Doc and Kid Suburbia clapped and grinned, plunged into the passion of Polar Sam.
Blow to the size of the large screen, the details become clearer. “Look! There are sailboats in the lake. ”
Sam’s “remote control” chip.
“There’s another kayak”, “and two swans”, “three ducks!” “Those people are fishing?!” All the water captured the imagination of the boys. The Santa Fe River barely runs, and spring has only one month at most. Or in August’s “monsoon season” rains.
“Where can we get all this water?” Doc Plaza asked suspiciously. “Of course, it’s noticeable, but as Santa Fe gets bigger and bigger, all the water has flowed into the new home, and the river is rather dry.”
“Those’Life machines’are excellent. Imagine that there are several greenhouses in every block. Biological products can decompose anything, even PCBs! “Sam has started now. “So we go into sewer lines, solar pumps into greenhouses, and in a series of high-end translucent glass fibre tanks, water is purified by biomass. Add ultraviolet disinfector and Wallah! Freshwater, higher quality than the original tap water! So the neighbors got fresh fruits and vegetables and fish in the sink, the river was filled all year round, the aquifer was replenished, and the water eventually fed back to Rio Grand without any pollutants, such as medicines! ”
The boys cheered again. The suburban children stared at Polar Sam incredibly. In his ice cream delivery, Uncle Sam’s vest and tail, and his red and white peeled hat, “He looks a little like a clown,” the child said to himself. But seeing the elegance and beauty of his vision in front of him… “This guy is a genius,” he said to himself.
Speaking loudly, Kid Suburbia lashed out, “Can you take it off the Peace Pop stick?”
Sam just laughed at him. “Oh, there’s more!”
Sam continued, “You know how you say it’s so boring, and there’s a group of old ladies living in a 2,400-square-foot house near your home? When the children grow up, their husbands die, or they divorce, but she lives alone, and she wants to stay near her home? Well, imagine these small squares surrounded by Casitas. Your ladies and friends can scale down and stay with their neighbors. She can remain independent and take long walks with friends and shopping. If she needs it, she can get help from the children in the local elementary school. ”
Doc Plaza interposed: “It sounds like a new version of the past, like a big family. I can stand this. ”
The children’s suburban residents laughed. “Yes, then all your girlfriends will be in one place.”
“Hey, don’t knock on it,” Doc retorted. “If I don’t shoot you first, you can live longer than your wife. It’s a great thing to make things easier for people in the middle of the day.”
Kid Suburbia is quiet. “My best friend Harold has been complaining about moving to a smaller place. He wanted to stay in the hood, but he was tired of keeping such a big house. I miss him already. It would be great if our community had one of these high-level Placitas! ”
“Hey brother!” Sam almost shouted. He raised the child’s paw to five. “Welcome to the amazing power of Box in Village!” Four people exchanged senior five. They didn’t know exactly why, but Bells’enthusiasm made them sell it.
Not every gas in the atmosphere absorbs intensely long-wave radiation from the ground. The greenhouse gases in the earth’s atmosphere are called greenhouse gases, mainly carbon dioxide (CO2), methane, ozone, nitrous oxide, freon and water vapor. They absorb almost all the long-wave radiation emitted from the ground, and only a very narrow region absorbs very little, so they are called “window region”. It is through this window that the earth returns 70% of the heat from the sun to the space in the form of long-wave radiation, thus maintaining the ground temperature unchanged. The greenhouse effect is mainly due to the increase in the number and variety of greenhouse gases by human activities, which makes the 70% value decrease and the remaining heat makes the earth warm.
What is greenhouse gas?
However, although CO2 and other greenhouse gases have a strong ability to absorb long-wave radiation from the ground, their amount in the atmosphere is very small. If the atmospheric state of pressure as a atmospheric pressure and temperature of 0 C is called the standard state, then the whole atmosphere of the earth is compressed to this standard state, its thickness is 8000 meters. At present, the content of CO 2 in the atmosphere is 355 ppm, or 355 parts per million. Converting it to the standard state, it will be 2.8 meters thick. This is 2.8 meters thick in the atmosphere of 8,000 meters thick. Methane content is 1.7 ppm, corresponding to 1.4 cm thick. The ozone concentration is 400 ppb (ppb is one thousandth of ppm), which is only 3 mm thick after conversion. Nitrous oxide is 310 ppb, 2.5 mm thick. There are many kinds of freon, but the most abundant Freon 12 in the atmosphere is only 400 ppt (ppt is one thousandth of ppb), converted to the standard state of only 3 microns. This shows that there are few greenhouse gases in the atmosphere. It is also for this reason that human release without restrictions can easily lead to rapid global warming.
History of development
As early as 1938, British meteorologist Carlinda pointed out that CO2 concentration had risen by 6% since the beginning of the century after analyzing sporadic CO2 observations around the world at the end of the 19th century. He also found that there was a warming tendency in the world from the end of last century to the middle of this century, which caused great repercussions in the world. To this end, Kellin of Scripps Oceanographic Research Institute established an observatory in 1958 at an altitude of 3,400 meters in the Maunaroya Mountains of Hawaii, and began the precise observation of atmospheric CO2 content. Because Hawaii is located in the middle of the North Pacific Ocean. Therefore, it can be considered that it is not affected by terrestrial air pollution and the observation results are reliable.
From April 1958 to June 1991, the atmospheric CO2 concentration in the Maunaroya Mountains was observed. It was found that the atmospheric CO2 content in 1958 was only about 315 ppm, which reached 355 ppm in 1991. The seriousness of the problem also lies in the fact that only about half of the 5.5 billion tons of fossil fuels (about 4 tons of CO2 per ton) that humans burn annually (1996) enter the atmosphere and the rest are mainly absorbed by marine and terrestrial plants. Once the ocean is saturated with CO2, the atmospheric CO2 content will increase exponentially. In addition, they also found seasonal variations in CO2 content, with a difference of 6 ppm between winter and summer. This is mainly due to the winter drought and summer glory of vegetation on the vast continents of the Northern Hemisphere, that is, plants absorb CO2 in summer, which makes the atmospheric CO2 concentration relatively lower.
According to the determination of CO2 concentration in the air of sealed bubbles in the Antarctic and Greenland continental ice sheets, the CO2 content in the atmosphere has been relatively stable for a long time in the past, about 280 ppm. Only from the mid-18th century, before and after the Industrial Revolution began to rise steadily. That is to say, it took 240 years for human beings to increase the atmospheric CO2 concentration from 280 ppm to 355 ppm.
Methane is the second most important greenhouse gas after CO2. Although its concentration in the atmosphere is much lower than CO2, its growth rate is much higher. According to the Second Climate Change Assessment Report issued by the Intergovernmental Panel on Climate Change (IPCC) in 1996, CO2 increased by 30% in 240 years from 1750 to 1990, while methane increased by 145% in the same period. Methane, also known as biogas, is produced when organic matter decays under anoxic conditions. For example, paddy fields, compost and animal manure all produce biogas. Nitrogen monoxide is also known as laughing gas, because inhaling a certain concentration of this gas can cause facial muscle spasm, which looks like laughing. It is mainly produced by burning fossil fuels and organisms using chemical fertilizers. Although the ozone content in the atmosphere decreases in the stratosphere, it increases in the troposphere, which will be discussed later. Freon gases are compounds of chlorine, fluorine and carbon; they do not exist in nature and are entirely human-made. Because of its low melting point and boiling point, non-flammable, non-explosive, odorless, harmless and excellent stability, it is widely used in the manufacture of refrigerants, foaming agents and cleaners. Although the highest concentrations of Freon 12 and 11 in the earth’s atmosphere are very few, their growth rates have been very high in the past, both of which are 5% per year. Because of its severe destruction of the ozone layer in the atmosphere, its concentration in the atmosphere is expected to decrease gradually from the beginning of the 21st century according to the 1987 International Montreal Protocol.
It should be noted that although the atmospheric concentration of greenhouse gases other than CO2 is much lower than that of CO2, some of them are several orders of magnitude smaller, their greenhouse effect is much stronger than that of CO2. Therefore, their contribution to atmospheric greenhouse effect, according to the second IPCC Report, is only one order of magnitude lower than that of CO2. If their total contribution to the greenhouse effect of the Earth’s atmosphere is small compared with CO2 before 1960, it is not negligible that in the near future they will go hand in hand with CO2 and even exceed CO2.

Earthworms, commonly known as earthworms, also known as Eel, are the representative animals of Oligochaeta in annelida. Earthworms are saprophytic living animals. They live in humid environment and feed on corrupt organic matter. They are full of a large number of microorganisms but seldom get sick. This is related to the unique number of antimicrobial immune systems in these earthworms.
In scientific classification, they belong to unidirectional earthworms. The body is cylindrical (distinct from the cylindrical shape of linear animals), symmetrical on both sides and segmented: it consists of more than 100 segments. After the Eleventh segment, there is a dorsal foramen in the middle of the back of each segment; there is no skeleton, it belongs to invertebrates, with bare body surface and no cuticle. Except for the first two segments of the body, all the other segments have bristles. Hermaphroditism, allogeneic fertilization, reproduction by the ring to produce cocoons, reproduction of the next generation. There are more than 2500 known earthworms. Darwin pointed out in 1881 that earthworms are the most important animal group in the world’s evolutionary history.
Body wall and secondary body cavity
The body wall of earthworms consists of cuticle, epithelium, circular muscular layer, longitudinal muscular layer and coelomic epithelium. The outermost layer is a single layer of columnar epithelial cells whose secretions form cuticle. The membrane is very thin, consisting of collagen fibers and non-fibrous layers with small holes. Cylindrical epithelial cells were mixed with fine glands cells, divided into mucous cells and protein cells, can secrete mucus and make the body surface moist. Earthworms encounter intense stimulation. Mucous cells secrete a large amount of mucus to wrap the body into a mucous membrane, which has a protective effect. Epithelial cells have short basal cells at the base, and some people think that they can develop into columnar epithelial cells. Sensory cells aggregate to form sensory organs and disperse between epithelial cells. The nerve fibers of a thin layer of nerve tissue under the epithelium are connected at the base. In addition, there are photoreceptor cells, the base of epithelium, also connected with the nerve fibers below it.
The muscles of earthworms belong to the twill muscles, which generally account for about 40% of the body volume. They are well-developed and flexible. When the longitudinal muscular layer of some segments of the earthworm contracts and the circular muscular layer relaxes, the segment becomes thicker and shorter, and the retracted bristles born on the body wall obliquely extend into the surrounding soil; at this time, the circular muscular layer of the former segment contracts, the longitudinal muscular layer relaxes, the segment becomes thinner and longer, and the bristles retract, thus breaking away from the surrounding soil. The bristle support of the latter segment pushes the body forward. In this way, the contraction wave of muscles gradually passes forward and backward along the longitudinal axis of the body.
The coelomic compartment is separated by the septum according to the body segment, and each compartment is connected with a small hole. Each body chamber is formed by the development of left and right two body sacs. The medial part of the sac formed visceral membranes, while the dorsal and ventral parts formed dorsal and peritoneal mesenteries. In earthworms, the mesentery of the abdomen degenerates, only part between the intestine and the abdominal vessels exists, while the mesentery of the back disappears. The part between the anterior and posterior coelomic sacs is closely together, forming a septum. Some species have no septum in the esophagus.
The digestive tract runs longitudinally in the central part of the body cavity and passes through the septum. The muscular layer of the wall of the digestive tract is well developed, which can improve peristalsis and digestive function. The digestive tract is differentiated into mouth, mouth, throat, esophagus, sand sac, stomach, intestine and anus. The mouth can be turned out from the mouth to ingest food. The pharyngeal muscles are well developed, the muscles contract, and the pharyngeal cavity enlarges to support feeding. There is a single-cell pharyngeal gland outside the pharynx, which secretes mucus and proteinase, moisturizes food and has a preliminary digestive effect. After pharynx, there is a short and thin esophagus with esophageal glands on its wall. It can secrete calcium and neutralize acidic substances. The back of the esophagus is a muscular sand sac (gizzard), lined with a thick cutin membrane, which can grind food. From mouth to sand sac, the ectoderm is formed and belongs to foregut. The digestive tract behind the sand sac is rich in microvessels and glands, which is called stomach. There is a circle of gastric glands in front of the stomach, which functions like pharyngeal glands. The digestive tract enlarges to form the intestine, and its dorsal central fovea enters into a blind canal (typhlosole), which enlarges the area of digestion and absorption. Digestion and absorption are mainly performed in the intestine. The outermost visceral membranes of the intestinal wall specialize into yellow cells. Since the 26th body segment, a pair of conical cecum (caeca) extending forward from both sides of the intestine can secrete a variety of enzymes, which are important digestive glands. The stomach and intestine originate from the endoderm and belong to the midgut. The posterior intestine is relatively short, accounting for about 20 body segments in the posterior end of the digestive tract. It has no blind passage and no digestive function. Open to the body through the anus. The digestive system of earthworms consists of more developed digestive ducts and glands. The digestive ducts are composed of oral cavity, pharynx, esophagus, crop sac, sand sac, stomach, small intestine, cecum, rectum and anus.
Earthworms are very special. Like their body segments without obvious merger, their hearts are also divided into several segments in the front of the body, generally 4-5, which are circular, like enlarged blood vessels, so they are also called circular blood vessels. The dorsal side of the annular heart is connected with the dorsal blood vessel from the back to the front, and the ventral side is connected with the abdominal blood vessel from the front to the back. The abdominal blood vessel and its branches are connected with the inferior nerve blood vessel from the front to the back. The annular heart has thicker muscular walls than blood vessels and pulsates. There are also valves that open unilaterally to ensure blood flow from the dorsal to the abdominal vessels. Generally speaking, the blood flow is powered by the pulsation of these independent annular hearts. The direction of blood flow is from back to front (in the dorsal vessels), from back to abdomen (in the annular heart), and from front to back (abdominal vessels and subnervous vessels).
Respiration and Excretion
The excretory organs of earthworms are posterior renal tubules. In general, each segment has a pair of typical posterior renal tubules.
Biotechnology is a well-known term. The National Science and Technology Commission defines biotechnology as “biotechnology contains a series of technologies that can produce the products we need from organisms or cells, including gene recombination, cell fusion and some biological manufacturing processes.”
In fact, human beings have a long history of using organisms or cells to produce the products we need, such as tillage 10,000 years ago, animal husbandry to provide a stable source of food, fermentation technology to brew wine and make bread 6,000 years ago, fungus to treat wounds 2,000 years ago, and use in 1797. Smallpox vaccine, the discovery of antibiotic penicillin in 1928, etc.
Since human beings have been using biotechnology for so long, why has biotechnology suddenly attracted widespread attention since 1990? This is because since the 1950s, the scientific community has had a better understanding of the cells that constitute the smallest unit of organisms and the genes that control the genetic characteristics of cells, as well as the development of gene recombination and cell fusion techniques in the 1970s. Since these two technologies can enable cells or organisms to produce the substances we need more effectively, and contribute to industrial or agricultural production, a new biotechnology industry has been created since the 1980s.
Bill Gates said in 1996 that “biotechnology will change the world like computer software”. Modern biotechnology industry has been developing since 1980, and its applications include pharmaceuticals, agriculture, environmental protection, food processing, special chemicals and other industries. In the field of biomedical pharmaceuticals, 155 biotechnology drugs or vaccines have been approved by the Food and Drug Administration of the United States and used to treat diabetes, heart disease, cancer, AIDS and other diseases. In agriculture, genetic recombinant plants such as papaya, tomato, maize and soybean have been listed. These plants are characterized by strong resistance to pests and diseases, and can reduce the use of chemical pesticides.
The progress of human civilization is from the collecting society of early fishery hunting life to the agricultural society dominated by farming and animal husbandry, and then to the modern industrial society. Because of the increasing population and the over-exploitation of industrial land, the area of agricultural cultivated land has been reduced. In addition, the generation of greenhouse effect has also accelerated the extinction of species other than human beings, making the food problem become a very important core issue in the 21st century. With limited resources and unlimited human growth, some people have come up with the idea that if food could be increased by high technology, there would not be a day when food would be eaten up. Therefore, with the vigorous development of biotechnology, many things that could not be done before can be done today in the 21st century. Many impossible tasks can be accomplished through biotechnology, such as the use of smears or patches to influence body fat to achieve beauty and weight loss, or the use of Botox is an example of biotechnology.
Since human beings, people have tried to transform organisms. Traditionally, breeding and mating were used to acquire desired biological traits (such as sweet and tasty corn) and to reduce or eliminate undesirable traits (such as natural toxicity). On the other hand, food is a necessity for human growth, and the population has increased rapidly recently. In view of the shortage of food, so-called “artificial food” has begun to emerge. However, the biggest limitation of traditional breeding is that the mating varieties must be the same or similar. In order to break through this limitation, modern genetic engineering technology should be used scientifically to select the genes with some excellent characteristics of organisms accurately and transfer them to another species so that the new genetically modified organisms have the expected specific characteristics.
Data from the Food and Drug Administration (FDA) show that in 1991, Calgene applied for genetically modified tomatoes to transfer antisense polygalacturonase (PG) gene into tomatoes, delaying the maturation and softening of tomatoes. In 1994, the company’s “Flavor” (FLAVR SAVR) tomato was the world’s first approved genetically modified food. The PG gene that promotes the ripening of soft enzymes in delicious tomatoes is inhibited, so its texture is more solid, and it can reduce the damage and deterioration during harvesting, transportation and processing, thus preserving the flavor. At present, however, commercial production of tomatoes has ceased. In 1994, there were 29 applications, including soybeans, tomatoes, corn, potatoes, cotton and melons. Monsanto is one of the big companies.
In addition, in environmental protection, some toxic industrial wastes and contaminated crude oil have been decomposed by recombinant microorganisms. In food, fermentation engineering technology has been used to produce healthy foods such as lactic acid bacteria, Ganoderma lucidum and Cordyceps sinensis. In special chemicals, recombinant enzymes have been used to produce drugs or fibers. Or use it in detergents to decompose dirt. By 2001, there were about 1500 biotechnology companies worldwide, with an annual output value of $30 billion.
The technology of gene recombination and cell fusion is the cornerstone of modern biotechnology. In recent years, many new technologies and new applications have been developed on this basis. For example, protein engineering technology can be used to improve the structure and activity of proteins, and Bionanotechnology can be used to manufacture biosensors, biochips and drugs. Transport systems, tissue engineering technology can use stem cells to repair damaged organs, and animal replication technology can use nuclear transfer to replicate animals, etc.
The development of biotechnology aims at curing diseases, improving the quality of life, providing food that is not scarce and protecting our living environment. However, if not strictly monitored during the development of biotechnology, it may cause harm to human beings or the ecosystem of the earth. Attention should also be paid to its impact on humanity, morality or ecology.
As the application of biotechnology is very extensive and closely related to our daily life, there are often related reports in general newspapers and magazines or news media, so understanding new knowledge of biotechnology should be included in our regular study.
The task of biotechnology is to explore the mystery of life and master the law of life movement.
- Genetically modified products
- Genetically modified food
- brief introduction
The application of science and technology brings convenience, but also brings unknown fears. When the technology of gene recombination is widely used in the development of biology, medicine, agriculture and industry, and may even enter more fields in the future, which deeply affects our lives, we seem to realize that this is an irresistible trend. Therefore, it is more correct to have a positive understanding of genetically modified foods, to think rationally about acceptability, and to leave the right of choice to everyone.
The so-called “genetic modification” refers to the selection of specific genes for individual traits of organisms and the alteration of their genome composition and expression. Scientists use different biotechnologies, such as restriction enzymes, to make target gene fragments, then connect DNA fragments to “vector” DNA molecules, and then transfer vectors to target chromosomes. This process is a kind of genetic engineering.
Different from the traditional breeding method, the transfer of traits is limited to individuals of the same species or similar provenances. Modern genetic engineering technology has broken through the traditional pattern of breeding. It can insert foreign genes from different provenances into plants in a “man-made” way. In addition, genes can even be derived from microorganisms or animals. Body. For example, insecticidal crystalline toxin gene (cry-gene) from Bacillus thuringiensis was implanted into maize, which can also synthesize insecticidal toxin protein produced by cry gene. Therefore, it has insect-resistant characteristics. This maize with cry gene implanted artificially can be called a GMO.
GMO (genetically modified organism) can generally be divided into three categories, namely:
Genetically modified microorganisms (and their products): including microorganisms that can be used as fermented food or as food additives such as enzymes, aminoacids, organic acids, vitamins, pigments and spices.
Genetically modified crops (and their processed products): This is the fastest growing area in GMOs. Transgenic crops such as soybeans, maize, tomatoes and potatoes have been introduced.
Transgenic animals (and their processed products): Salmon transfected with growth hormone gene, but most of them are at the research stage.
Genetically modified foods (GMF = GM foods), also known as genetically modified foods, are processed by GMO. Therefore, all foods derived from genetic recombination technology are called genetically modified foods. How does genetically modified food come into being?
Generally speaking, there are two main ways to implant functional foreign genes into plants. For dicotyledons such as soybeans, tomatoes and cotton, gene transfer is usually achieved by Agrobacterium tumefaciens. Agrobacterium crown can naturally (i.e. without any artificial treatment) infect a wide variety of plants by inserting a segment of its own DNA directly into the DNA of infected plants, so long as the oncogene in Agrobacterium crown DNA is removed, and the foreign gene to be inserted into the stem of Agrobacterium crown. Bacteria infect plants so that additional genes can be transferred to the DNA of infected dicotyledons. Cells containing additional genes in infected plants can be further screened out, and cell culture techniques can be used to produce complete plants containing additional genes. As far as monocotyledons (e.g. maize, wheat and rice) are concerned, Agrobacterium crown is not very effective in infecting them. Generally, the foreign genes to be implanted are coated on tungsten balls, and then the tungsten balls coated with foreign genes are physically introduced into plant cells, some of which have foreign bases. As part of plant DNA, these plant cells containing foreign genes can be screened out and cultured into complete beads because they fall off from the surface of tungsten particles. In addition to Agrobacterium coronatum, plant viruses are often used as vectors, but not all plant viruses have the function of vectors unless the virus can be dispersed between cells via plasmodesmata, and foreign genes must be replicated and the modified viral nucleic acid can infect plant cells. It does not cause symptoms, and the virus must be widely parasitic. Generally speaking, DNA is the main target of gene transfer. RNA-containing viruses are considered only when viruses using DNA are not effective. It is preferable for plant viruses to contain DNA rather than RNA as vectors. However, only caulimo virus and Gemini virus are known to contain DNA, among which caulimo virus and Gemini virus are used. The latter is widely favored by researchers because it can infect dicotyledons and monocotyledons and has a wide range of hosts.
Controversy over genetically modified foods
In recent years, biotechnology has been gradually applied to food production, so the derivatives of genetically modified foods have also been listed on the market. There are still many controversies about the impact of genetically modified food on human body, which requires long-term and extensive research. In order to understand the public’s knowledge and attitude towards genetically modified foods, the Department commissioned a survey on “the public’s knowledge and attitude towards biotechnology and genetically modified foods” by private companies. It is hoped to understand the public’s attitude towards genetically modified foods and their views on labeling policies, which will serve as a reference for future government to formulate relevant laws and regulations. According to.
Threats to the environment include:
(1) threats to non-target organisms and beneficial insects;
(2) reduction of biodiversity;
(3) gene drift and genetic pollution.
The main economic impacts are as follows:
Loss in the market
Although the crop itself will not move, food made from it can be sold everywhere, which also arouses many people’s concerns about genetically modified crops. In 2000, Nature magazine reported that Star Link Corn, an unauthorized genetically modified maize for human consumption, had flowed into Japan’s food distribution network. Star corn is not allowed to be eaten by humans in Japan, although it can be used as feed in the United States, mainly because it contains an insecticidal toxin called Cry9C, which is thought by scientists to cause allergic reactions after being eaten. In the past, about one third of the maize exported by the United States was exported to Japan, while the European Union purchased about 40% of the soybean exported by the United States. Consumers in these areas have doubts about the food safety of genetically modified maize or soybean, which will pose a great threat to future exports of the United States.
For farmers growing organic crops, if they are cross-pollinated or mixed with genetically modified crops, they will suffer serious marketing problems due to poor quality, especially maize and sugar beet, which are cross-pollination plants. In this way, farmers who produce organic agricultural products will have to temporarily withdraw from the organic product market, and their income will drop sharply before they get organic certification again.
Bio Engine Composting Part 2
Classification by type of fermentation plant
According to the type of fermentation device, there are vertical composting fermentation tower, horizontal composting fermentation drum, silo composting fermentation tank and box composting fermentation tank.
1 vertical compost fermentation tower
Vertical composting fermentation tower usually consists of 5-8 layers. The composting material enters the tower from the top of the tower. In the tower, composting moves from the top of the tower to the bottom of the tower through different forms of mechanical movement. Generally, after 5 to 8 days of aerobic fermentation, the compost is moved from the top of the tower to the bottom of the tower to complete a fermentation. Vertical composting fermentation tower usually has a closed structure. The temperature distribution in the tower gradually increases from the upper layer to the lower layer, that is, the lowest layer has the highest temperature. In order to ensure the activity of microorganisms in each layer for high-speed composting and maintain the optimum temperature and ventilation volume of microorganisms in each layer of the tower respectively, the oxygen supply of the tower device is usually forced ventilated by a fan, and the air is quantitatively ventilated into the tower through the vents of different heights installed on the side of the tower body to meet the micro-generation. The demand for oxygen.
Vertical composting fermentation tower usually includes vertical multi-stage cylinder type, vertical multi-stage landing gate type, vertical multi-stage blade scraper type, vertical multi-stage movable bed type, etc.
2 horizontal composting fermentation drums
Horizontal composting fermentation drum is also called Danot type. The main equipment is a horizontal drum with a length of 20-35 m and a diameter of 2-3.5 M. In the fermentation device, waste is raised along the rotating direction by friction with the inner surface of the cylinder, and falls down by means of self-weight. By rising and falling repeatedly, the waste is evenly turned over and contacted with the air supplied, and fermented by microorganisms. In addition, because the cylinder is oblique, when the waste lifted along the rotating direction falls by its own weight, it gradually moves to one end of the outlet of the cylinder, so that the rotary kiln can automatically and steadily supply, transport and discharge compost. The processing conditions of the device are summarized as follows:
The ventilated air temperature is normal in principle. For a 24-hour continuous operation device, the ventilation rate is 0.1 m3/(m3.mm), and the rotating speed of stirring in the cylinder should be 0.2-3.0 r/min. If the whole fermentation process is completed in this device, the residence time should be 2-5 days. The filling rate of cylinder is generally as follows: waste volume in cylinder/cylinder capacity is less than capacity. The average temperature of compost in the whole fermentation process is 50-60 when the device is used, and the maximum temperature can reach 70-80 high. When the device is used for one fermentation, the average temperature is 35-45, and the maximum temperature can be about 60 high.
3 silo type compost fermentation silo
Silo-type compost fermentation silo is a single-layer cylindrical (or rectangular) fermentation silo, the depth of fermentation silo is generally 4-5 M. The upper part is provided with a feed inlet and a scraper diversion device, and the lower part is provided with a screw discharger. Most of them are made of reinforced concrete. High-pressure centrifugal fan was used to supply oxygen in fermentation chamber to maintain aerobic fermentation of compost in fermentation chamber. Air generally enters the fermentation bin from the bottom of the silo, and composting material enters from the top of the silo. After 6-12 days of aerobic fermentation, the compost with initial maturity was discharged from the bottom of the silo through the discharger. According to the movement form of compost in fermentation bin, silo fermentation bin can be divided into static and dynamic.
(1) Silo-type static fermentation bin.
The device is a single-layer cylinder with stacking height of 4-5 M. The compost enters the silo through the distributor from the top of the silo. After 10-12 days of aerobic fermentation, the compost is discharged by the screw discharger at the bottom of the silo. Because there is no repetitive cutting device in the warehouse, the raw materials are compacted and lumpy, the ventilation performance is poor, the ventilation resistance is large, the power consumption is large, and the product is difficult to homogenize. However, the device occupies a small area and has a high utilization rate of fermentation bin, which is its advantage. The structure of this device is simple, so it is widely used.
(2) Silo-type dynamic fermentation silo.
The silo-type dynamic fermentation silo is a single-layer cylindrical silo with a stacking height of 1.5-2 M. During the operation of the dynamic fermentation bin, the crushed wastes sorted by the pretreatment process are transferred to the middle of the top of the tank by the feeder, and then uniformly distributed by the feeder to the tank. The screw drill located in the rotating layer stirs the wastes in the tank by revolution and rotation, so as to prevent the formation of grooves, and the shape and arrangement of the screw drills can pass through. Maintain a uniform distribution of air. Waste falls from the top down in the pond by gravity. Rotary cutting screw device with revolution and rotation is installed at the bottom of the pool. Whether the upper rotating layer rotates or not, the product can be discharged from the bottom of the pool. The air required for aerobic fermentation is forced into the bottom of the pond through the air distribution board. In order to maintain the aerobic environment in the pond and promote fermentation, forced ventilation from the bottom of the pond was adopted by blower. By measuring the temperature and gas concentration in each section of the pool, the air quantity supplied to each section can be adjusted and the rotation period of the bridge tower can be controlled to change the overturning frequency. The period of one fermentation is 5-7 days. In the composting process, the helical blades cut off the raw materials repeatedly, and the raw materials are pressed on the helical surface, which is easy to produce compacted lumps, so the ventilation performance is not very good. In addition, it also has some shortcomings, such as uneven residence time of raw materials, uneven product shape and not easy to seal. Its advantage is that the height of the outlet and the residence time of the raw material can be adjusted.
4 Box composting fermentation tank
There are many kinds of box-type composting fermentation ponds and their applications are very common. The main classifications of box-type composting fermentation ponds are as follows:
(1) Rectangular fixed plough-shaped overturned fermentation tank.
The box-type composting fermentation pool is equipped with plough-type upside-down mixing device. The device acts as a mechanical plough to dig waste. It can regularly agitate and move materials several times. It can keep the ventilation in the pool, make the materials evenly disperse, and also has transportation function. It can move materials from the feed end to the discharge end, and the materials stay in the pool for 5-10 days. The air is forced to ventilate through the air distributor at the bottom of the pool. Fermentation tank adopts conveying mixing device, which can increase the height of material accumulation.
(2) Fan bucket overturned fermentation tank.
This kind of fermentation tank is horizontally fixed. It is equipped with a dumper to mix the waste so that the humidity of the waste is uniform and in contact with the air, which promotes the rapid decomposition of compost and prevents the generation of odor. The residence time is 7 to 10 days. The frequency of dumping waste is once a day as the standard. The number of dumping can also be changed depending on the material properties. The fermentation plant has several characteristics in operation: the fermentation tank is equipped with a mixer and an overturning car mounted on the truck conveyor. When the waste is overturned, the overturning car runs on the fermentation tank. When the overturning operation is completed, the overturning car returns to the movable car. According to the handling capacity, sometimes the traveling crane structure can not be installed. Vehicle conveyor; When the material in the pond is overturned, the mixer is lifted by rope traction or mechanical piston tilting device, and when it is overturned again, the mixer can be put down to start mixing; In order to transfer the overturning vehicle from one fermentation pond to another fermentation pond, the track conveyor and crane can be used to scrape out the conveyor and belt conveyor. Feeder or swing conveyor, compost is agitated by mixer, conveyed by vehicle conveyor at the end of fermentation pool, and finally scraped out of the pool by scraper conveyor placed on movable car. Several specific stages of fermentation process are controlled by a compressor, and the required air is blown in from the bottom of fermentation pool.
(3) Crane overturned fermentation tank.
This kind of fermentation tank is usually used for secondary fermentation. The compostable materials which have been crushed and sorted by the pretreatment equipment or which have been fermented once are sent to the fermentation tank by the conveying equipment, and the compostable materials which are fed into the fermentation tank are piled up in the designated box fermentation tank by the shuttle conveying equipment. During accumulation, air is supplied from suction trough, and hopper crane is used to overturn material and perform vaccination operation at the same time.
(4) Horizontal blade fermentation tank
The agitator blade is attached to the mobile device and then moves. Because the mixing device can move horizontally and vertically, the mixing device moves the mixing material repeatedly vertically and transversely at the same time. Because stirring can be used throughout the fermentation tank, the fermentation tank can be designed very wide, so that the fermentation tank has greater processing capacity.
(5) Horizontal scraper fermentation tank.
The main component of the fermentation tank is a flaky scraper driven by gear and rack. The scraper swings from left to right to stir waste, returns from right to left without load, and then swings from left to right to push a certain amount of material. The amount of material pushed by the scraper can be adjusted. For example, when stirring once a day, adjustable push volume is required for a day. If the treatment capacity is large, the fermentation tank can be designed into a multi-stage structure. The pool body is a sealed negative pressure structure, so the odor does not escape. The fermentation tank has many ventilation holes to maintain aerobic condition. In addition, sprinkler and drainage facilities are installed to regulate humidity.
The type of composting equipment used and the corresponding composting process usually depend on the following factors:
- Types of solid waste;
- Establishing natural conditions of composting plant site (distance from residential area, topography, wind direction, etc.);
- Control level of secondary pollutants (leachate, odor gas) in composting process;
Investment and operation cost of plant construction.
Because of the superiority of geographical location, stacking composting can be widely used in rural areas and small towns. However, in some densely populated rural areas, farms, aquaculture farms, urban suburbs and other areas, the composting process with high efficiency for odor gas and leachate treatment should be chosen first.
Trend of development
The Seattle Solid Waste Utilities Bureau first implemented the Masterminer Program in the United States in 1986, marking the beginning of household composting, which mainly uses composting technology to treat yard waste and food waste. In 1995, 41% of Seattle households implemented household composting, diverting about 8 300 tons of yard waste, 82% of which was used for yard greening. There are studies. In the Mississauga area of Ontario, roadside collection, centralized composting and household composting cost $140 t-1, $190 T-1 and $50 t-1, respectively. Moreover, household composting can reduce the amount of household garbage by 3%-5%. Compared with centralized and large-scale composting systems, household composting has significant advantages: low cost and reduction of solid waste sources. In Seattle, there are two types of household composters for food waste: earthworm boxes and conical buckets. In the past, earthworm boxes were commonly used. Now, conical barrels are popular. The height of conical barrels is about 0.9 M. There is a basket with a height of 0.46 M. It can accommodate food waste produced by a family of three within 6 to 9 months. There are two kinds of household composters for yard waste: 0.34 m3 and 0.59 m3. Wood, recycled polyethylene and stainless steel are used to make household composters.
Composting toilets are suitable for places without or without water, such as large-scale composting toilets for parks, highways, stations, etc., and small-scale composting toilets for ships, etc. The commercial composting toilets are divided into self-contained and centralized ones, which can be operated intermittently or continuously, and are made of glass fibre and polyethylene. The self-contained composter is located next to the toilet, while the centralized composter is located next to the basement or building. Intermittent composting toilets contain more than one compartment. When one compartment is full, they are transferred to another compartment. Its advantage is that there is only one compartment in the composting toilet which can run continuously without contamination by fresh manure. Fresh manure and decomposed quasi-manure are mixed together.
Small Capacity Reactor Suitable for Field Operation
Because of the economic, odor control and site reasons, composting systems with large reactors, forced ventilation static stacking and strip stacking are greatly limited. Therefore, a portable, small-capacity reactor composting system suitable for field operation emerges as the times require. For example, Mulch Co. of County, UK, has built two mobile composting systems (30.584-38.23 m3 in volume) similar to rolling containers, with bucket loaders for feeding and cranes for lifting containers when discharging, and materials poured out from the back door of containers. Temperature and oxygen content are controlled by computer. Although this kind of system has only appeared for a few years, it is receiving more and more attention and application from small sewage treatment plants, food industry, catering industry, communities, schools, hospitals, research institutes and business groups. At present, it is mainly used for food waste treatment. The small capacity reactor composting system on the market includes box system, mixing bin and rotary digester, etc. But at present, the most commonly used one is box composting system. The system can be operated intermittently or continuously. It has the advantages of good process control, low investment and operation cost, simple equipment, easy operation and assembly, etc. But its greatest advantage is that it is easy to operate and assemble. Organic waste treatment technology is provided for groups or units that do not have enough space. Currently, 50 and 25 box composting systems are operating in the United States and Canada, respectively. A typical box-type composting system has a treatment scale of 1-40 t/d-1. It consists of several boxes, two of which are used as biofilters. In order to facilitate field operation, the mixing equipment and reactor are connected with the trailer.
In a word, the source of solid waste is more and more dispersed, and the amount of solid waste is also more and more, so the application scope of composting equipment will gradually expand. For different solid wastes, different composting equipments need to be adopted and developed. With the development of solid waste composting, household composters and small-capacity reactor composting systems emerge as the times require. On the one hand, home composters have been reduced from the source.

Decomposition Technology of Raw Chicken Manure Composting
Can chicken manure be used as organic fertilizer if it is not ripe? Chinese style
1. Not only chicken manure, but also human manure contains a lot of pathogens, eggs and parasites. Unripe manure can not be directly applied to crops.
2. Chicken manure will dissipate most of the heat in the process of ripening. If it is not fertilized directly, it will cause burning roots and seedlings of plants.
3. Nitrogen fertilizer in chicken manure originally existed in the form of protein. Plants could not use protein directly. Only when protein was decomposed into ammonia after fermentation, can they be used by plants.
How to decompose chicken manure?
Chicken manure must be fully decomposed before it is applied. The parasites and eggs in chicken manure, as well as some infectious pathogens, are inactivated through the decomposition process. Because chicken manure produces high temperature in the process of decomposition, it is easy to cause nitrogen loss. Therefore, it is better to add water and 5% calcium superphosphate before chicken manure is decomposed. Chicken manure has become a good base fertilizer for crop cultivation after full maturation. It can be used for all kinds of flowers, seedlings, crops and fruit trees.
The traditional method is to compost chicken manure for fermentation and maturation, which usually takes 3-4 months to mature. Nowadays, through the rapid biological decomposition technology of Nongshengle chicken manure, the decomposition rate can be 10-20 times faster than the traditional method by aerobic fermentation, and the protein and other substances of chicken manure can be converted into more easily absorbed elements such as nitrogen, phosphorus and potassium. After complete decomposition, chicken manure can hardly smell odor. Fermentation of chicken manure with Nongshengle Fecal Fermentation Fermentation Fermentation Fermentation Fermentation Fermentation has the advantages of low dosage, good effect and fast speed. Generally, chicken manure can be completely decomposed in 7-15 days. If the fermentation material is pure chicken manure, under normal conditions, the C/N ratio is generally less than 20, it should be added with appropriate amount of straw, sawdust and other materials with high C/N ratio. Straw can be added as much as chicken manure to mediate the C/N ratio, and because compost fermentation is aerobic fermentation, straw can enhance the looseness and permeability of chicken manure, which is more conducive to fermentation.
Note: It is recommended to use rice, corn, wheat, sawdust and other plant straw with larger carbon and nitrogen content, and to avoid using straw with smaller carbon and nitrogen content, such as beans. Chinese style
Method of decomposition of chicken manure: Before fermentation, mix all kinds of materials evenly and reserve them. During fermentation, the manure starter of Nongshengle was diluted and mixed with chicken manure mixture at the ratio of 1:200. Then it could be accumulated and fermented. The fermentation process is dumped 1-2 times, and the decomposition can be completed in 7-15 days according to the season.
Knowledge of organic fertilizer clinker: The ratio of total carbon content to total nitrogen content in organic matter is called carbon-nitrogen ratio, and their ratio is called carbon-nitrogen ratio.
C/N ratio of common plants:
- In general, the C/N ratios of gramineous crop stalks such as rice stalks, corn stalks and weeds are very high, reaching 60-100:1.
- The C/N ratio of leguminous crop stalks is relatively small, such as the C/N ratio of general leguminous green manure is 15-20:1.
Effects of different C/N ratios on Composting
The decomposition and mineralization of organic matter with high C/N ratio is difficult or slow. The reason is that when microorganisms decompose organic matter, they need to assimilate about one part of nitrogen to form their own cell body when they assimilate five parts of carbon, because the carbon-nitrogen ratio of microorganisms is about 5:1. In order to assimilate (absorb and utilize) one portion of carbon, four portions of organic carbon are needed to obtain energy, so 25 portions of organic carbon are needed for microorganisms to absorb and utilize one portion of nitrogen. That is to say, the ratio of carbon to nitrogen of microorganism decomposition of organic matter is 25:1. If the ratio of carbon to nitrogen is too large, the decomposition of microorganisms will be slow and the available nitrogen in soil will be consumed. Therefore, when applying organic fertilizers (such as rice straw) with high C/N ratio or composting materials with high C/N ratio, more N-containing fertilizers should be added to regulate C/N ratio. On the contrary, there are too many nitrogen elements in chicken manure, so more carbon elements such as straw should be added. Chinese style
How to reduce the use cost of chicken manure ripening agent:
In order to reduce the use cost of chicken manure ripening agent, the manure fermentation strain (original strain) was developed and manufactured. Users could use the manure fermentation strain to cultivate the fermentation agent by themselves, which could reduce the cost by 10 times. Chinese style
Benefits of Feed Fermentation

- Detoxification and detoxification, improve palatability and intake;
- Improving animal immunity and reducing fecal discharge;
- Enhance meat quality and flavor to make meat delicious.
Ways to Make Composts
How to Compost
The Method of Making Compost Fertilizer from Straw
- Method of composting:
- Site selection Fertilizer-making site should be located in the leeward sunward area with flat terrain and close to the water source, which can be made in the open air all the year round. A kind of
- Material preparation (Take 1 ton of dry straw as an example)
(1) 1000 kg of crop straw.
(2) 20 kg corn flour or wheat bran or rice bran, and 5-10 kg urea can be added if conditions permit.
(3) Bacillus Yikang compost fermentation strain 400g (two bags of this product).
(1) The length of straw (e.g. corn straw) should be 1-3 centimeters when it is crushed or cut by a hay cutter (wheat straw, rice straw, leaves, weeds, peanut seedlings, bean straw, etc.) can be fermented directly, but the fermentation effect is better after crushing.
(2) Water the crushed or cut straw with water to wet and permeate, and the moisture content of straw is generally controlled at about 60%.
(3) Mix 20 kilograms of corn flour (or wheat bran or rice bran) with 400 grams of bacteria. Sprinkle corn flour (or wheat bran or rice bran) mixed with bacteria evenly on the surface of straw irrigated with water by hand. Use spade and other tools to turn over and mix, stack into long strips of 2 meters wide, 1.5 meters high and unlimited length, and cover them tightly with plastic cloth.
(1) Warming up stage: from room temperature to 45 C, generally only one day, at this time can turn over the stack.
(2) In the future, when the heap temperature reaches above 60 C, it needs to be turned over, and the basic state of decomposition can be reached in 15-20 days, and the fertilizer can be applied directly. Maturity mark straw turns brown or black-brown, soft and elastic when wet, brittle and fragile when dry.
(1) Straw fertilizer is generally used as base fertilizer and can be applied wetly. Soil should be covered for topdressing. Semi-decomposed fertilizer is applied to crops with longer growth period, straw fertilizer with higher maturity is applied to crops such as melons, fruits and vegetables with shorter growth period, semi-decomposed fertilizer is used in sandy soil, and fertilizer with higher maturity is best applied to clay soil.
(2) Straw fertilizer is rich in organic matter, balanced nutrients of nitrogen, phosphorus and potassium, and contains various trace elements. It is a suitable fertilizer for all kinds of crops and soils. It has remarkable effects on improving crop quality and increasing yield. A kind of
Note: It is suggested that 20-30% livestock and poultry manure or other organic substances should be properly added in composting, so that the fertilizer efficiency is better and more comprehensive.
（3）Rapid Fermentation of Straw Returning to Field:
Quick Returning Technology: Digging Trough – Stacking Straw – Adding Bacteria and Yikang – Sealing
1) Digging trough: Digging a low trough 1.5-2 m wide and 0.3 m deep in idle fields such as fields and courtyards, the length of which can be determined according to the amount of straw. _
2) Stacking straw: According to the standard of 60% moisture content of straw (i.e. holding the water in groups and keeping the watermarking by hand without dripping, it is appropriate to lay down and disperse), so that the straw can absorb enough moisture and accumulate straw in the tank.
3) Adding organic fertilizer starter: first, add 1 bag (200g) of Bacteria Yikang to dilute 20 kg corn flour or rice bran or wheat bran (1000 kg straw material), then stack straw while adding animal manure or urea to adjust C/N ratio and evenly sprinkle corn flour with Bacteria Yikang. Or rice bran or wheat bran.
4) Sealing: When the pile is about 1:5 meters high, photograph it and seal it with clay or plastic film. About 15 days in summer and 40 days in winter can be fertilized and returned to the field.
Quick in-situ Returning Technology of Straw Returning to the Field: Straw Crushing-Adding Bacteria Yikang and Feces-Sealing-Tillage-Tillage
1) Straw crushing: The straw is crushed into small segments of about 3-4 cm with a crusher.
2) Add Bacteria Yikang: first, add 2 bags of Bacteria Yikang (400 grams) into 40 kg corn flour or rice bran, wheat bran dilution; decomposed feces and urine 300 kg; all kinds of straw 700 kg. Mix the above materials well, then add water, adjust the moisture content of straw to about 60%, accumulate in the earth and compact slightly. A kind of
3) Sealing: After accumulating the material, the material is sealed with mud. A kind of
4) Tillage: Sprinkle the rotten straw evenly on the ground, and immediately carry out deep tillage, raking and further maturation of the straw.
Rapid Decomposition and Return of Rice Straw to Field Technology Harvesting Fertilizing Adding Green Seedlings to Strengthen Throwing Seedlings
1) Harvesting: one is to keep high stubble harvested, tail grass left in the field, 100% straw returned to the field; the other is low stubble harvested, after threshing also returned to the field in full.
2) Fertilization: Planned application of organic and inorganic fertilizers in the field.
3) Bacterial Yikang: According to 1000 kg of straw, add 500 grams of Bacterial Yikang, evenly sprinkle in the field. When applied, the water layer in the field was 2-3 cm.
4) Seedling throwing: After applying Bacillus Yikang, the farmland can be thrown for one day. When throwing rice seedlings, the surface of the field should maintain a certain water layer. The water layer of the high stubble paddy field and straw strip mulch is shallow, 2-3 cm. The paddy field covered with straw is deep, about 5 cm. Submerged straw is the standard to ensure the contact between seedling roots and water.
Technical Operating Points
1) Adequate moisture: straw must absorb enough water, the moisture content is generally controlled at about 60%. A kind of
2) Adjust the appropriate C/N: Add appropriate amount of animal manure or nitrogen fertilizer to regulate the C/N of the compost.
3) Blend material: Bacteria Yikang added should be evenly sprinkled in straw, or stirred evenly with utensils.
4) Ventilation: Microorganisms ferment faster under aerobic conditions, and the condition of ventilation will directly affect the stalk maturation rate. So don’t step on it when stacking, in order to facilitate ventilation. After stacking, it is sealed with mud mixed with straw. When the temperature in the stack exceeds 65 degrees, ventilation or dump should be adopted.
5) Sealing: When stacking, the surrounding and top of the reactor should be sealed to prevent water evaporation and nutrient loss.
6) Warming up: When composting straw in winter or cold area, plastic film is added to the compost to increase the temperature. Fourth, attention should be paid to the sufficient moisture content of materials for stacking and composting, the uniform mixing, sealing, heat preservation and water retention, so as to ensure that straw is quickly matured and accumulated without stepping on it, and take a slight photo.
Last, the suitable area, all kinds of straw crops can be treated by straw composting and returning technology after harvesting.
