What are the development directions of corn stover?

Cultivated forage biopower plant ethanol.

Summary. Comparing the nutrient composition of the two y, corn stalks The freshly harvested corn stalks have higher nutritional value, but with the extension of the storage period (wind, sun, rain), the loss of nutrients is larger. Generally, the crude protein content of corn straw is about 4-5%; The crude fiber is about 25%, the digestibility of the crude fiber of cattle is about 65%, and the crude ash content is more than 30% of the nitrogen-free extract; Dry matter digestibility of various parts of corn stover:

Stems, leaves, cores, bracts, whole beads.

Therefore, the nutritional value of corn straw with more leaves is higher, the crude fiber content is higher than that of corn straw, and the crude protein content is lower, which is 1 3 of corn straw, and wheat straw is a type of roughage of poor quality compared with corn straw. However, after a certain amount of treatment, it can also be used as roughage. So corn stalks are more nutritious.

Corn straw is a grain, economic and forage crop for feed, and corn straw is also an important production resource for industrial and agricultural production. As a species, corn stover is rich in nutrients and available chemical components that can be used as a raw material for livestock feed. Corn stover has long been one of the main roughage raw materials for livestock.

Hello, the utilization value of corn straw includes: straw returning to the field: it can be directly returned to the field, high-temperature composting, etc.

Straw feed: It can be used as a raw material for silage or ammoniated feed for animal husbandry. Straw biogas:

It is less perishable than a manure digester and has a higher gas production rate. Straw production of edible mushrooms: After crushing, it can be fermented to produce edible mushrooms such as mushrooms, oyster mushrooms and chicken leg mushrooms.

Summary. Development of the cattle industry. Corn straw contains sugar, amino acids and other nutrients, which can be used as raw materials for ammoniated feed in the cattle industry.

Cultivation of edible mushrooms. Corn stover can be used to grow edible mushrooms. Implanting the strain into the fermented corn stalk can breed high-quality edible fungi.

as industrial raw materials. Corn straw is a fibrous plant, which can also be used as industrial raw materials for papermaking and plate processing.

Corn stover can be used to grow edible mushrooms. Implanting the strain into the fermented corn stalk can breed high-quality edible fungi. as industrial raw materials.

Corn straw is a fibrous plant, which can also be used as industrial raw materials for papermaking and plate processing.

Make biogas. Corn straw is a carbohydrate organic matter, which can be used to produce biogas as fuel after sealing and soaking, alleviating the current situation of rural electricity and fuel shortage, and saving costs. as soil fertilizer.

That is, used as a raw material for making farmhouse fertilizer, the introduction of stalk crusher and the supporting deep tillage agricultural machinery can be used to crush the corn stalk and return it to the field, increase soil organic matter, improve soil fertility.

Corn straw reuse, reduce incineration to protect the environment, make green storage feed to breed cattle and sheep to improve economic returns, and increase income by 600 yuan per mu.

So what if you use the factory to produce what to solve? Corn straw can be used to grow edible fungi, with low cost, high efficiency and good market prospects.

Straw ammoniation technology, so that cattle and sheep are raised.

In addition to being used for feed and straw returning, corn straw can also be extruded into blocks and used as a raw material for biomass power generation. Every 10,000 tons of corn straw can produce about 7 million kWh of electricity. At present, small biomass thermal power plants with corn straw as the main raw material have been built in corn producing areas.

Corn stover can also be fermented by biogas to produce heat, which replaces coal and electricity to provide energy for cooking and heating in rural areas. Corn stover is also a raw material for man-made boards, pulp and paper, cultivated mushrooms and corn stover crafts. At present, many scientific research units at home and abroad are studying the production of fuel ethanol from corn straw as a raw material to replace part of gasoline.

Corn stover has"Waste to control pollution"、"Pollution is cured by pollution"The advantages of low cost and easy availability of raw materials are new ideas for environmental protection and pollution control in industry and agriculture, and have important practical significance for agricultural development.

1. Straw returning to the field. This is by far the most straightforward and easiest way to exploit it. Including direct return to the field, high-temperature composting, over-belly returning, etc.

2. Straw feed. Corn stalk is a good raw material for the development of animal husbandry. After being used as feed, its by-product manure is a good raw material for fertile fields. It is divided into silage, ammoniated feed, etc.

3. Straw biogas. Compared with manure digesters, straw digesters are less perishable, have a higher gas yield, replace coal and electricity, and provide energy for cooking and heating in rural areas.

4. Straw production of edible fungi. After the corn straw is crushed, it can be fermented to produce edible mushrooms such as oyster mushrooms, chicken leg mushrooms, mushrooms, etc., and the waste materials can be returned to the field as farm fertilizer.

5. Straw papermaking. The packaging material produced by corn straw is small in size, light in weight, good in compressibility, degradable and pollution-free, and is a method of industrial utilization that can be vigorously developed. The use of straw papermaking can replace wood pulp paper, and the pollution-free and clean pulping technology in the field of straw pulp and paper makes the paper industry more energy-efficient and environmentally friendly in the next few years.

6. Straw energy. Straw can be converted into solid, liquid, and vapor fuels. The straw is processed into machine-made charcoal, which can be used in metallurgy, chemical industry, construction, rural horticulture, animal husbandry, domestic fuel and other occasions; Gasification of straw and conversion into alcohol fuel are new ways of straw utilization; Corn stover can also be used as a raw material for biomass power generation by extruding into lumps.

Corn straw is also a raw material for man-made boards and corn straw handicrafts.

It can be used as silage for ruminants such as cattle and sheep, and it is okay to purchase **.

1. Straw accumulation and fermentation to increase soil fertility, 2. Straw crushing to make animal feed for animals. 3. It is used as a fuel for cooking rice and brewing, which is clean and environmentally friendly. 4. Straw returning to the field. 5. It is used for fermentation to make biogas. 7. Straw papermaking.

It can be broken up and put in the ground as fertilizer.
