Is it OK to crush corn stalks in the ground?

It is better to crush the straw and return it to the field. Straw returning is a method of applying straw (wheat straw, corn straw and rice straw, etc.) that is not suitable for direct feed into the soil directly or by stacking and rotting.

Steps: 1) Straw returning to the field is generally used as base fertilizer. Because of its slow release of nutrients, the late season crops cannot absorb and utilize. [4]

2) The amount of straw returned to the field should be moderate. Generally, the amount of straw returned to the field is 150 250 kg of hay per mu, and when the quantity is large, it should be combined with the corresponding tillage measures and the appropriate amount of nitrogen fertilizer should be applied.

3) Straw application should be even. If it is uneven, it is difficult to plough the thick place into the soil, so that the field surface is uneven, and it is easy to cause uneven crop growth and uneven seedling.

4) Appropriate amount of fast-available nitrogen fertilizer should be applied deeply to adjust the appropriate carbon to nitrogen ratio. Generally, the cellulose content of grass crop straw is higher, up to 30% to 40%, and the carbon matter in the soil will increase sharply after returning to the field, generally about 1 times. Because the growth of microorganisms is based on carbon as energy and nitrogen as nutrition, and the appropriate carbon-to-nitrogen ratio for the decomposition of microorganisms by organic matter is 25 1, and the carbon-to-nitrogen ratio of most straws is as high as 75 1, so that when the straw is decomposed, due to the imbalance of carbon and nitrogen and less, the microorganisms must absorb nitrogen from the soil to make up for the deficiency, which also causes the phenomenon of competing for nitrogen with crops, so it is particularly important to increase nitrogen fertilizer when returning straw to the field, which can play a dual role in accelerating the rapid decomposition of straw and ensuring the vigorous growth of crop seedlings.

No, because the corn stalks have a high moisture content, even if they are briquetted, they can't be stored, they don't burn, and the yield can't keep up with the harvester. Because of its narrow contact surface with oxygen, briquetting smoke pollution is large, so the market now recognizes straw pellets. Jinan Guanbei Machinery is a manufacturer specializing in the production of straw pellet fuel machines.

The treatment method of broken corn straw is mainly used as feed for herbivores, such as cattle, sheep and rabbits, and can also be used as straw to return to the field.

of high-quality organic fertilizers.

First, corn stalks are fermented to make silage.

Fodder. Silage technology belongs to biological treatment technology, which is to chop, collect or manually harvest the corn at the ripening stage through the silage harvesting machinery at one time, and then crush the green corn straw to 1 cm 2 cm long to make it contain water.

It is 67% 75%, add silage starter such as golden fungus to the straw, stir evenly and store it in cellars, tanks, towers, pools and plastic bags for compacted and sealed storage, artificially create an anaerobic environment, and naturally use lactic acid bacteria.

Anaerobic fermentation produces lactic acid, which makes most microorganisms stop multiplying, and lactic acid bacteria stop growing due to the continuous accumulation of lactic acid, and finally stop growing by the lactic acid produced by themselves, so as to maintain the nutrition of green straw and make silage have a slight fruity flavor, which livestock prefer to eat.

Second, corn straw is fermented to make organic fertilizer.

The straw is directly returned to the field or directly returned to the field after crushing, and 1kg of straw rotting agent such as golden fungus is used per mu, which is sprayed under pressure and can be completed in 10-15 days. The straw after being decomposed by the straw rotting agent of Nymphus aureus can effectively improve the organic matter in the soil, enhance the activity of soil microorganisms, and improve soil fertility. For example, the golden fungus straw rotting agent can speed up the decay of the straw, not only that, but also the yeast contained in the golden straw rotting agent.

Lactic acid bacteria and bacillus can secrete cellulase.

Hemicellulase, etc., can effectively degrade cellulose and other macromolecules in straw into activated small molecule substances, which can be absorbed by crops. Moreover, for example, various beneficial bacteria contained in the straw rotting agent of the golden fungus multiply in the straw, inhibit the growth of miscellaneous bacteria and miscellaneous eggs in the straw, and can effectively reduce the probability of crop diseases and insect pests when applied to the soil.

To sum up, straw can be used to make silage, but also can be decomposed to make organic fertilizer, hidden circle is such a valuable thing, if you find such a golden fungus earlier, you must be able to use straw in exchange for more money. So from now on, don't throw away the straw at will.

1. Preparation of raw materials. First, the corn stalks are crushed or cut into small segments or filaments as required, in which the feed raw materials used to feed cattle, horses and mules should be chopped into 2-5 cm, fed sheep and deer should be chopped into about 2 cm, and the straw or vines fed to pigs, chickens, ducks, geese and rabbits should be crushed. It can be fermented with straw starter alone, or with corn flour for feeding, which is better.

2. Mix raw materials. Adjust the humidity: add water to the prepared straw material and stir evenly, and the water content is controlled at 60 left, and the judging standard is:

Grasp a handful of materials with your hands, and see that the water does not drip between your fingers, and it is advisable to let go of it. The ratio of straw to water is approximately: about 1.

According to the ratio of 600 kg of fermentation straw of 1 kg of Nongshengle fermentation bacterial liquid, the starter is evenly sprayed on the material with a new watering can (sprayer), and the wine should be sprayed to make it even. 3. Sealed fermentation. After mixing the above-mentioned straw and sealing it, the user can build a fermentation pond and process it in batches, and the fermentation time in summer and autumn is 5-8 days, and the fermentation time in winter is 10-15 days.

4. Fermentation control. When used for feed fermentation, it is anaerobic fermentation, and the fermentation process should be sealed to prevent deterioration. 5. Feed feeding.

Layer by layer from the outside to the inside, the socks can be kept for a longer time. Fermented feed can be fed individually or in a full-price feed. Livestock and poultry fed fermented feed for the first time should be fed a small amount first, and after adaptation, the amount of feed can be gradually increased.

Summary. Ferment.

1. After the pretreatment is completed, pile the materials to be fermented into a large pile of 1 high, and cover it with a breathable covering;

2. The first fermentation. Fermentation takes place in two stages. The first time is the beginning of fermentation to 25 30 days, heat preservation and moisturizing measures should be strengthened to promote the saccharification of the fermented product, after 5 7 days of fermentation, so that the fermentation temperature reaches 45 50, and the white mycelium appears on the surface of the fermented product (it takes more than 2 days) to turn over and pour for the first time.

Then the fermentation is continued, so that when the cumulative fermentation temperature reaches 800 900, the second fermentation period (second inversion) begins.

3. Second fermentation. Pay attention to make the fermentation water content generally controlled at about 60%, when the water is insufficient, you can fully fill 5% of the urea solution, and then increase the thickness of the accumulation appropriately, re-pile into a large pile, continue to ferment, after two weeks of temperature of 65, three weeks after the temperature of 60, the cumulative temperature of fermentation reaches 800 1000, basically stop fermentation. After the fermentation is completed, the fermented materials are dried to make the water content reach 40 5%, and the bags are stored in a ventilated and dry place.

How to deal with crushed corn stalks with mulch.

After fermentation 1 and pretreatment are completed, the materials to be fermented are piled into a large pile of 1 height, and the air permeable cover is covered on it; 2. The first fermentation. Fermentation takes place in two stages. The first time is the beginning of fermentation to 25 30 days, heat preservation and moisturizing measures should be strengthened to promote the saccharification of the fermented product, after 5 7 days of fermentation, so that the fermentation temperature reaches 45 50, and the white mycelium appears on the surface of the fermented product (it takes more than 2 days) to turn over and pour for the first time.

Then the fermentation is continued, so that when the cumulative fermentation temperature reaches 800 900, the second fermentation period (second inversion) begins. 3. Second fermentation. Pay attention to the fermentation water content is generally controlled at about 60%, when the water is insufficient, you can fully water 5% urea solution, and then increase the thickness of the accumulation appropriately, re-pile into a large pile, continue to ferment, after the temperature of 65 for two weeks, the temperature of 60 after the three keys open for a week, the cumulative temperature of the fermentation reaches 800 1000 base source, the fermentation can be basically stopped.

After the fermentation is completed, the fermented materials are dried to make the water content reach 40 5%, and the bags are stored in a ventilated and dry place.

Take a look, dear.

The role of corn stover:

1. Straw has become nutritious feed.

After crushing and puffing the cut straw through a new type of straw extruder, and then fermenting for about 15 days, it is processed into a kind of extruded feed rich in microorganisms and higher nutrients.

2. Feed processing.

In addition to being directly fed as feed, corn straw has a variety of processing technologies in physics, chemistry and biology that have been popularized and applied in practice, realizing centralized large-scale processing and opening up a new way of feed utilization.

3. Silage. Lactic acid bacteria are naturally used for anaerobic fermentation to produce lactic acid, so that most microorganisms stop reproducing, and lactic acid bacteria are controlled by their own lactic acid due to the continuous accumulation of lactic acid, and finally stop growing by their own lactic acid, so as to maintain the nutrition of green straw, and make silage with a slight fruity flavor, livestock prefer to eat.

Summary. It is best to control the length of the corn stalk at about 1-2cm when cutting, if the corn stalk is too long, it is not easy to compact, and it is easy to rot and deteriorate.

OK. It is best to control the length of the corn straw at about 1-2cm when cutting, if the corn straw is too long, it is not easy to rise and compact, and it is more noisy and easy to rot and deteriorate.

Also pay attention to keep the moisture, add less water and then more, while loading and adding, while compacting, the amount of water should be based on the actual water content of the raw materials, and the total water content of the stored material should reach 65%-75%.

Attention should be paid to the amount of water added at any time, and the water seeps out when the storage material is held in a clump, but there is no dripping water between the fingers, and it is advisable to slowly spread it after letting go of the hand.

The purpose of compaction of raw materials is to maximize the discharge of unbridled air, so that it is in a state of hypoxia, to provide favorable conditions for the reproduction of lactic acid bacteria, and to squeeze out the juice in the raw materials to provide nutrients for the multiplication of lactic acid bacteria.

Finally, pay attention to sealing to prevent rainwater from flowing in, which will lead to moldy and deterioration of the straw.

Summary. Corn stover is the main feed for many animals. Therefore, how to maximize the nutritional value and palatability of corn stover has become an important issue in a certain way of storage.

Yellow storage is a good storage method. The preparation of yellow silage for storage generally requires that corn seeds be harvested as soon as possible after they are mature, and the corn stalks should be yellow siled immediately. The harvested raw materials should be stored while harvesting, minimizing exposure to the sun and avoiding accumulation and heat to ensure the freshness of the storage materials.

Try to avoid harvesting and transporting storage materials on rainy days to reduce soil pollution.

The harvested raw materials should be stored while harvesting, minimizing exposure to the sun and avoiding accumulation and heat to ensure the freshness of the storage materials. Try to avoid harvesting and transporting storage materials on rainy days to reduce soil pollution.

The key to the success or failure of yellow silage lies in adding water, so experienced personnel should be arranged to add water specially. The specific method of adding water is: if the water content of the raw material is high, no water can be added in the pre-filling time, and a small amount of water can be added only after filling to 50-80 cm from the cellar mouth.

If the raw material is not too dry, the amount of water needed to add the stool stall is less, and the water should be gradually added at about half of the storage filling. If the raw material is very dry, you should start adding water gradually when the jujube storage material is 50 cm thick. Add water should be in line with the principle of less and then more, while filling, compacting, and adding water, and the amount of water added should be determined according to the actual moisture content of raw materials, and the total moisture content of the stored material should reach 65 -75, too much or too little is not good.

After the raw materials in the cellar or trench are filled and compacted, they must be sealed and covered with a coarse cover. The method of sealing and covering can be to cover a layer of fine and soft grass first, and then cover the remaining plastic film around the cellar or trench on the storage material, and then cover it with a layer of plastic film, and press it around the storage trench or storage cellar with soil, and then cover it with a layer of 30-50 cm of soil. The top must be higher than the edge of the cellar or trench and dome-shaped to prevent rainwater from flowing into the cellar or trench and causing the storage material to rot.

Summary. The first storage method is to crush and make yellow storage, which is widely used by farmers who raise fattening cattle by crushing and packaging yellow storage by machines. Through fermentation after baling, the active ingredients in the straw are converted into nutrients that are very suitable for cattle digestion, thereby reducing the input of concentrate feed and maximizing the profit of cattle raising.

This kind of yellow storage is simple to make, and it is also very convenient to store, generally a package is about 100 catties, and it is also very labor-saving to handle. To make this kind of yellow storage, you need to buy a hay cutter and a baler, and then calculate the amount of one cow used a year according to the number of cattle raised. Generally, the feed intake of a fattening cow is about three tons a year, which is basically enough according to this standard.

The second method of processing corn straw yellow storage is cellar storage, and the main principle of cellar storage is also through compacting and sealing fermentation, so that the sugar and crude fiber in corn straw are converted into roughage that cattle like to eat through fermentation. The technology of cellar storage is mainly compaction and sealing, the crushed straw is transported to the cellar pool, and then the weight of the large loader is used to press back and forth in it, and it is sealed after full compaction. Attention needs to be paid to the sealing, not to cover the top with sand or soil, after compaction, cover it with plastic film, and then use a heavy object to press on it to avoid breathability and decay.

However, sand and gravel or soil cover will cause yellow storage failure due to excessive clostridium, so it should not be used as much as possible.

Can semi-dry corn stover be crushed and compacted for storage.

What I'm talking about is that you can't do yellow storage when it's dry, but there is a little bit of moisture, and you can ask if it can be briquetted?

Yes, dear.
