First, straw as fertilizer (1) directly to the field. One is to keep high piles. The wheat straw should be 5-6 inches high, and the back rake should be a dry crop such as corn. The high stakes in the empty row should be destroyed after the cultivator and weeding. The second is paving and covering grass. The straw is covered in orchards, corn, vegetables and other lines, or the wheat fields are sown and covered with grass. It not only returns the organic matter to the soil, but also plays a role in protecting the earthworms, increasing (decreasing) the temperature, lowering the salt, and increasing the elimination effect. Generally, 150-200 kilograms of hay are laid evenly per acre, and fruits and vegetable gardens can be more. (2) Animals return to the abdomen. Herbivores use straw as their feed. After digestion and absorption, their feces return to the field. (3) Build up piles and fertilizers. The compost is made of straw and livestock dung. The dung and grass are stacked and compacted. In this way, it can promote ripening and improve fertilizer efficiency. Straw can also be used to make grass mud ponds, straws can be put into the digester, and finally returned to the field.

Second, straw for animal feed straw ammoniated, crude protein from 3% -4% to about 8%, organic matter digestibility increased by 10-20 percentage points, and contains a variety of amino acids, can replace 30% -40% The concentrate feed. Weed seeds can also be killed to prevent mildew. Therefore, the ammoniated straw is fed to sheep and cattle, and the effect is very good. Straw can also be crushed into grasshoppers for animal feed supplements.

Third, straw as an industrial raw material After honing the straw fiber and resin mixture in the metal mold pressure forming, can be made into a variety of low-density fiber sheet. The pressure and chemical treatment on the surface can be used for the production of decorative plates and one-time molding furniture. It has the characteristics of high strength, corrosion resistance, fire retardant, beautiful appearance, and low price. The development of such straw boards is of great significance for alleviating the inconsistency of domestic timber supply and tight supply and demand, saving forest resources and developing the wood-based panel industry. Can also be used to produce disposable chopsticks, fast food boxes, natural biodegradable after use, non-toxic and harmless without any environmental pollution.

Fourth, straw as a base straw is the basic material for mushroom cultivation. After the straw is crushed, it can account for 75%~85% of the cultivation material of edible fungi. Straw bag material cultivation of edible fungi is a common method for producing oyster mushrooms, shiitake mushrooms, enoki mushrooms, and coprinus comatus by using stalks at present. It has the technical measures of saving investment and quick effect, and can handle straw in large quantities, and is welcomed by farmers.

5. Straw energy stalk energy technologies include straw gasification, straw briquetting, and domestic fuel. Among them, straw gasification has already begun to be widely applied in China. (Liu Zhaochuan Li Bo)
