What is the function of the straw formed after corn dries up?

After the corn is harvested, the straw can be used as feed for green storage and returned to the field to cultivate fertility. Corn stover is dried and crushed and used as livestock and poultry feed or decomposed into organic fertilizer. Corn stover is primarily used as fuel after harvesting, but it can also be broken down back into the field or to assist in the production of organic fertilizer.

Green straw harvested from corn <> can be used as green fodder, or crushed back to farmland, or broken down into fertilizer, or processed into wood charcoal. In the past, the largest use value of corn straw in rural areas was used as fuel, in the past, rural families used stoves to burn cauldrons, and a lot of fuel was needed for cooking and heating every day, and it cost a lot to buy coal or wood for a year, so farmers had to pull the straw home to use fire, and corn straw was not resistant to burning, and the branches were easy to stain the house, but after all, it was free. But now that there are fewer permanent residents in the countryside, every household is using gas and electricity, so there are fewer and fewer corn stalks to burn.

Use corn stalks.

As a raw material, bagasse significantly reduces costs and saves the country a lot of wood. So, use corn stalks. Corn cob.

Silk waddling shell. Peanut shells. Sorghum stalks.

Crops such as bagasse wheat bran are cultivated, thus saving a lot of wood for the country, not only reducing the termination cost, but also solving the problem of environmental pollution, especially high-energy cattle feed, which can replace part of the corn and grain. The disadvantage of corn stover is that it is low in protein and calcium, which needs to be supplemented. Straw silage can not only keep the stems and leaves fresh and juicy, but also produce lactic acid and other substances through microbial action during the silage process to improve palatability.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

Straw is chopped, additives are added, and after closed fermentation, silage is made. Silage contains a large amount of amino acids, crude fiber and other nutrients, and is a rare and high-quality feed for pigs, cattle, sheep and other livestock. The straw of wheat and corn can be broken and fed to cattle and sheep when the forage is fed, which not only saves the cost of breeding, but also gives full play to the reuse of straw.

It can be used as a nutrient, that is, for those herbivores to eat. It can boost their digestion and help them develop better.

It can be used as farmhouse fertilizer, and it can also bury the straw in the soil to ferment naturally, and the effect is very good, which can greatly reduce the cost.

Corn stalk is a common farmland waste in the north, with a large yield. If it is not used rationally, it will waste resources and affect agricultural production. If incinerated, it can also pollute the environment. Let's talk about the other functions of corn stover.

1. Fertilizer. Destroy the corn stalks with a destructor or cut them with a straw cutter. The normal length is 1-3 cm. The destroyed or cut straw is wet and infiltrated with water, and the straw contains water.

Generally, it is controlled at about 70%. Mix 40kg of cake flour with bacterial fertilizer starter culture, and sprinkle the cake flour mixed with bacterial fertilizer starter culture evenly on the surface of the watered straw. with a shovel.

Or other tools are turned and mixed again, stacked into strips of 2 meters wide and high, and of unlimited length, and covered with plastic sheets to make fertilizer suitable for crops.

2. Feed. Straw feed must be processed with straw, such as: crushing, storage, temperature and humidity, which has different requirements for different organisms.

In order to save costs, most people choose the natural fermentation method. It uses the microorganisms contained in the straw itself for fermentation. During fermentation, temperature, humidity and pH.

It is constant, and it is necessary to use activators to produce straw feed with certain nutritional value, which also improves the palatability of feed to a certain extent.

3. Fuel. Corn stover is an abundant renewable resource.

Mainly composed of cellulose.

Hemicellulose and lignin.

Compose. Corn stover is pre-treated, hydrolyzed, and fermented to produce alcohol. By adding other compounds, such as straw, animal manure, etc., for chemical reactions, and then processing them by machines to make pellet fuel, not only greatly saving fuel costs, but also causing very low pollution during combustion.

4、**。Many corn farmers in rural areas will choose to give corn stalks to surrounding power plants, farms and other places, and agree with them for long-term cooperation. This also brings great convenience to many farmers who grow corn in a small area, and also provides them with some income.

The above are the other functions of corn stalks, I hope to help the majority of netizens.

It can be used as feed, firewood, and electricity. Fresh straw can be fed to livestock, dried and then used for heating and used as raw materials for power generation after being processed by large machines.

Corn stalks can be used as combustibles, heating, incineration, or building materials, and these stalks can be collected and transported to local factories for waste use.

After the corn harvest in the fall, the processing of corn stover becomes a big problem. If burning corn stover not only pollutes the air, but is also very unsafe, then what should corn stover be disposed of?

First, after the corn straw is ground into powder, the edible fungus culture material is added.

After the mushroom is cultured, the residue becomes bran feed, which can account for 10% of the diet when fed to piglets. It can be used to feed fattening pigs. It accounts for 20% -30% of its diet, and can be 30% -50% of its diet when fed to cattle.

Second, the straw pile fermentation.

1) Straw compilation is a process in which a series of microorganisms mineralize and humify organic matter such as crop straw. Through composting, the carbon and nitrogen ratio of organic matter can be reduced, the nutrients in organic matter can be released, and the spread of germs, insect eggs, and weed seeds in compost can be reduced. Therefore, the decomposition process of compost is not only the process of decomposition and resynthesis of organic matter, but also the process of harmless treatment.

2) Production method, choose a convenient place to get water at the corner of the field, dig it down manually, and make the field line. Field pipelines are required to be as flat as field embankments (capable of storing water). Rice stalks are generally piled up in one pile per mu (barley and wheat are piled in two acres), each pile of straw weighs about 500 kg, and covers an area of 6 - 7 square meters.

Straw stacking, each layer is 40 cm high, watered enough (it is better to use biogas slurry), so that the moisture content of straw is 60% 70%, and sprinkled with rotting fungicide; Each stack can be stacked in 4-5 layers, about one person high, barrel-shaped pile, requiring kilograms of decomposer. The top of the pile is concave to facilitate the concentration of rainwater. After the straw is piled up, it is generally laid for 3-5 days to start fermentation.

After 1 month, it enters the high-temperature fermentation period. Generally, the pile can basically be decomposed after 2-3 months. Secondly, the outer layer of the straw is converted into the middle layer and water is added to facilitate the uniform decomposition of straw fermentation.

When the next crop is planted, the fully decomposed straw and organic fertilizer can be returned to the field to reduce the amount of chemical fertilizer. Cover (make holes in the recesses), moisturize and keep warm, and if it's too dry, water from the top.

3. Biological treatment method.

In order to activate the wheat straw starter culture, add 1000 grams of warm water, 30 grams, then add 500 grams of brown sugar, stir well, wait for it to dissolve completely, and let it stand for about 3-5 days. The activation is basically completed, and the activated bacteria should be sealed and preserved. Then use 1:

Dilute the activated inoculum with 300 water for later use. Prepare 30 kg of corn flour. Corn flour and wheat straw are used alternately.

First of all, add a layer of straw flour with a thickness of 10-20 cm at the bottom of the bag, compact it when loading, sprinkle a layer of corn flour after each layer of straw is sprinkled, and repeat the cycle. When the straw powder is packed at a distance of 20 30 cm from the mouth of the bag, it is compacted and sealed. Pay attention to this, try to expel the air from the pouch and let it ferment tightly.

The fermentation time is closely related to the ambient temperature, and the fermentation usually starts above 10 years. The higher the temperature, the faster the fermentation. When the temperature is above 20, fermentation generally takes about 5 days; When the temperature is around 15°C, it takes about 10 days.

After the straw and flour are fermented, the bag mouth should be tied immediately after each time, and the bag mouth should be sealed and stored. Eat when you're full.

First, after deep cultivation, the straw is buried in the soil and turned into organic fertilizer; the second is to pick up the straw from the surface and feed the cattle or use it for fire; The third is to directly burn the straw in the ground, turn it into ash, and scatter it into the ground.

Straw can be buried in the soil, can be turned into farm fertilizer, can be turned into feed for crops, can be stored, never burned, otherwise it will affect the air.

We can water, so that the rate of decay can be accelerated, nutrients can be provided to the soil, we can also carry out deep ploughing, and we can also spray some pesticides and fungicides in time.

The straw after the corn harvest can be used as fertilizer or as fodder.

Collect all these things and use them to make fires, and the effect of these things to make fires is very good.

Some chickens, ducks and geese need to use soft straw bottom, straw bottom, can well maintain the combination of animal manure and straw, keep the house hygienic environment, dry environment, in addition to straw and animal manure have good adhesion, convenient for future processing of these manure.

These can be used as feed for some animals, but also as raw materials for other items, and can also be very useful, and can also be used as fuel, can also be called fertilizer, can be a binder for something, are all very useful.

Potassium can be extracted, which can alleviate the shortage of potassium in the market, can improve economic benefits, can also be used as fertilizer to continue planting, can also be used as feed to feed some livestock, can also be ground into powder to produce mushrooms, can also be used in some factories to make paper, which will be more resource-saving and more environmentally friendly.

It can repel mosquitoes, nourish the land, make fires, make paper, kill insects, and be used as feed.

Although corn straw burning treatment is very convenient, the burning process will have an impact on the natural environment, environmental pollution, and there is a potential safety hazard of causing fire. With the development of society, China attaches more and more importance to the problem of environmental pollution, and now the burning of crop straw is prohibited, I have seen the fine for burning straw, so corn straw is removed into concentrate feed, how can it be used?

It is strictly forbidden to burn corn stalks, except as concentrate feed for livestock. In the past, wheat straw. Some people in the wheat field to beat the slime**, I heard, containing high fiber, for the paper industry, and plywood.

I don't know how much fiber the corn stalks contain, but I haven't received it. Think about it, the fiber content is reduced. Corn stalks, storage baskets, sweet potatoes are used, but how much can be used.

Annoying, indeed. Many acres of bud rice are planted, and the straw still enters the drainage ditch, which is plugged to remove water and engulf the field. Neighbors don't allow it, and conscience is unbearable.

What's more, other injuries will be laughed at for generations, and it will be difficult to resist. Fortunately, there are plantation tea trees here, which are transported at the edge of the garden, and are covered with a guillotine. Increase the temperature of the garden to avoid the cold of the fruit oil tea trees in the garden, and reduce the weeds next year.

After a few years, the straw rots, improving the organic matter in the garden and enriching the fruit tea. If there is no tea plantation, hug into the ground, weeds can not be scattered next year, and the origin of weeds is a wonderful thing. Everyone, weeds must not run rampant, is not the welfare of farmers.

Straw returning. The return of bud rice straw to the field not only realizes the local use of corn straw, but also saves the cost of chemical fertilizer.

Straw returning is to fill in nutrients, potassium nitrate can be used, urea solution can also be used. When returning straw to the field, the length of crushing is not too long, make sure to bury it in the ground for at least 10cm, and tamp it, and at the same time need to pay attention to insect control to prevent the next round of crop pests and diseases. Mushroom cultivation.

Corn stalks can be used to cultivate fungi, which can produce additional economic benefits, and small investment, good effect, especially suitable for marketing and promotion among farmers. The bract cultivated mushroom can be used to shorten the straw, and it can also be cultivated as a whole, which is suitable for the cultivation of shiitake mushrooms and bisporus mushrooms.

After the corn straw is dried and crushed, it can be used as feed for livestock or decomposed into some organic fertilizer; The main reason is that our corn stalks are used for this purpose after being dried and crushed, and the effect is very good.

It can be used as fertilizer, which can increase the yield of crops, and can also be used to feed livestock; Because corn stalks can be crushed into organic fertilizer after being crushed in the sun, animals also prefer to eat them.

It can be used as green fodder or in the field. Finally, it can be decomposed into related organic fertilizers. It can also be processed into wood charcoal. I'm a farmer myself, so I know.
