Is there any good way to deal with straw?

The ways of straw utilization mainly include the following aspects:

1, Mechanized technology of straw harvesting and returning to field

The main way to harvest straw back to the field is to harvest it with a combine harvester, and at the same time, to crush the straw with a special device installed on the combine harvester and throw it on the surface.

2. Mechanized conservation tillage technology

This technology takes mechanized operation as the main means, and according to the requirements of crop cultivation, adopts the mode of less tillage or no-tillage sowing, and uses crop straw and stubble to cover and conserve moisture, thus effectively improving soil fertility, storing water and conserving moisture, preventing soil erosion, protecting agricultural ecological environment, reducing production cost and realizing agricultural sustainable development. The popularization of mechanized conservation tillage technology mainly includes straw mulching, no (less) tillage, fertilization and sowing, subsoiling, weed and pest control and other technical contents.

3, straw organic fertilizer production technology

This technology uses the preparation of high-temperature strains to quickly compost wheat straw into high-efficiency and high-quality organic fertilizer. Its principle is that under a certain humidity (about 65% of the straw's water holding capacity) and a certain temperature (50℃-70℃), various enzymes in the strain preparation and the fast decomposing agent are violently active, releasing energy, on the one hand, the cellulose of the straw is rapidly decomposed; On the other hand, a large number of bacterial proteins are formed, which are directly absorbed by plants or converted into humus.

4, straw cultivation of edible fungi technology

The technology is to select straw, mechanically crush it into small pieces, and use it as the base material to cultivate edible fungi. The technological process includes raw material preparation, adding auxiliary materials, batching, bagging, sterilization, inoculation, fungus growth and mushroom production management. This technology has mature formula and management technology. Straw is the basic raw material for edible fungi cultivation. After decomposition, open-field mushrooms can be cultivated 1 mu, producing 2000-3000 kilograms of mushrooms and earning 5000-6000 yuan. It is a rich technology with small investment, quick effect and low technical requirements, which can handle a large number of surplus straw and is well received by farmers.

5. Good raw materials for feed production, especially high-energy feed for cattle, can replace some corn seeds. The disadvantage of corn stalk is that the content of protein and calcium is low, so it 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 silage to enhance palatability.

6. Raw materials for biogas production. Corn stalk is a carbohydrate organic matter, which is made by sealing and retting.

Biogas can be produced as fuel to alleviate the current shortage of electricity and fuel in rural areas.

Situation, save money.

7, straw industrial processing technology

This technology mainly takes wheat straw and other straws as raw materials, integrates the processing principles of physics, chemistry, electricity, machinery and hydraulics, and uses high-pressure molding machinery and equipment to press and mold the mixture of crushed straw fiber and resin in a metal mold to make various high-quality low-density, medium-density and high-density fiberboard products, and then carries out pressure and chemical treatment on the surface, which can be used to make decorative boards and once-molded furniture. Straw board products have the characteristics of high strength, corrosion resistance, fire resistance, no deformation, no market, elegant appearance and low price. Developing straw board is of great significance for alleviating the contradiction between insufficient wood supply and tight supply and demand, saving forest resources and developing wood-based panel industry.
