The use of straw is very extensive. There are straw fertilizers, ruminants, abdomen returning, and straw cultivation for edible fungi in agricultural use; industrial applications include papermaking, straw boards, new wall materials, straw utensils, straw painting, stamping Rice, straw grass straw rope, etc.; In addition, straw can also be used as a new type of energy in rural areas, such as straw gasification, straw methane and so on. I. Straw fertilizer (stalk return) Mechanized rice straw returning machine to live wheat, high piles, rape grass cover; wheat straw planting machine transplanter; watermelon, melon and other melons, garlic covered straw. By returning the straw to the field, we can improve soil structure, increase fertilizer efficiency, and promote the virtuous circle of ecological agriculture. II. Feeding ruminants and returning to the field Develop herbivorous livestock and poultry, such as dairy cows and sheep, and digest large amounts of corn, peanuts, soybeans, straw, wheat and other straw, and convert them into edible meat and drinking milk. Feeding ruminants with corn, peanuts, and soybean straw should also be more scientific and thorough on the existing basis. It is very unscientific for some farmers to raise cattle with straw, such as yellow corn, and it is necessary to accelerate the popularization and application of straw silage technology. Through the feeding of ruminants and returning to the fields, a double benefit has been achieved. Third, straw cultivation of edible mushrooms China's straw cultivated edible fungi has a long history, and vigorously developed edible fungi such as mushroom and straw mushroom which use straw as the main base material, making it an important channel for the comprehensive utilization of straw. Fourth, industrial use Straw papermaking, straw board, new wall materials, straw tableware, straw painting, stamping rice, straw curtains, straw ropes, etc., straw has a very wide range of industrial uses. V. Energy Utilization Straw methane production (biogasification), straw pyrolysis gasification, straw power generation, straw production of solid shaped fuel, straw carbonization, straw cellulose hydrolysis to ethanol, biodiesel and so on. 1. Straw Biogas (Biogasification) Technology It refers to the technology that uses straw as the main raw material and microbial fermentation to produce biogas and organic fertilizer. The straw biogas technology is divided into two forms: household straw biogas and straw biogas centralized supply. This technology makes full use of straw, corn and other straw raw materials, effectively solves the problem of shortage of raw materials for human and animal manure in the promotion of biogas, and enables farmers without pigs to use clean energy such as biogas. The residual bioslag after straw influent into the pool is a good fertilizer, and can be used as organic fertilizer to return to the field (ie, returning the pond to the field), further improving the utilization efficiency of straw resources. 2, straw curing molding technology It refers to the technology of compressing crop straw into rod-shaped, block-shaped or granular shaped fuel under certain temperature and pressure. After straw molding, the volume is reduced by 6 to 8 times and the density is 1.1 to 1.4 tons/cubic meter. The energy density is equivalent to medium quality bituminous coal, the combustion characteristics are obviously improved, the fire power is long-lasting, and the furnace temperature is high. After the straw is solidified, it can effectively improve the transportation and storage capacity and expand the application range. Straw fuel can replace wood or coal to provide rural residents with energy for cooking or heating. It can also be used in cities as a boiler fuel to replace natural gas and fuel oil. 3, straw pyrolysis gasification technology Based on crop stalks, rice hulls, sawdust, branches and rural organic waste as raw materials, in the gasifier, combustion is controlled to produce combustible gases containing carbon monoxide, hydrogen, methane, and the like. At present, there are household straw gasifiers and straw gasification stations that provide centralized gas supply in residential communities and villages. 4, straw direct combustion power generation technology It means that the straw is directly burned in the boiler, and the released heat is usually used to generate high-pressure steam, so that the high-pressure steam expands in the steam turbine to do work, and is converted into mechanical energy to drive the generator to generate electricity. 5, straw carbonization It refers to the use of oxygen-limited autothermal pyrolysis process and pyrolysis gas recovery process to convert straw into biomass, charcoal, gas, tar, and wood acetic acid and other products in one system. Biochar and gas can be used as fuel for production and living of farmers or industrial users, and tar and wood acetic acid can be further processed into chemical products. This technology realizes the efficient use of straw resources and is suitable for the development of small-scale, multi-network construction and centralized deep processing. China's comprehensive utilization of straw is divided into low-end, conventional and high-tech types. The low-end and conventional types include straw agricultural use, papermaking, straw grass straw rope, straw painting, etc. High-tech includes energy, straw boards, new wall materials, straw cutlery, stamp rice and so on. Compared with the low-end and conventional technologies, most of the high and new technologies are not yet mature, and they require scientific and technological breakthroughs to gradually translate into actual productivity. In the short-term, relatively mature, low-end, conventional straw comprehensive utilization technology should play a major role, straw agricultural use should play the biggest role, among them, returning straw, farming ruminants back to the field, straw and straw processing, brokers to buy straw Should become the focus of comprehensive utilization of straw.
