Background
As one of the main sources of biomass materials, the straws produce 8 to 9 hundred million tons of straws every year in China. The method has the advantages of effective utilization, field protection, agricultural non-point source pollution treatment, air pollution prevention and control, and great significance in converting agricultural development modes and agricultural sustainable development. At the present stage, china has a lot of problems to be solved urgently in the aspects of straw treatment, soil structure improvement and the like.
Firstly, in the aspect of straw treatment, under the guidance of positive policies of governments, "five-material" comprehensive utilization researches such as straw fertilization, feed conversion, raw material conversion, base material conversion and fuel conversion are widely carried out, and the comprehensive utilization efficiency of straws is greatly improved. However, the existing straw utilization technology of "five-material" still has the problems of immature process technology, low production efficiency, high energy consumption, industry standard loss, unobvious economic benefit and the like, and the produced straw can not be effectively utilized, so that the phenomenon of large-area straw incineration occurs every summer and autumn, and the environment is seriously damaged. Therefore, how to effectively treat biomass materials such as straws and the like is a problem to be solved urgently at present.
In the aspect of soil structure improvement, farmland soil is utilized for a long time with high strength, the content of organic matters in soil in northeast regions is reduced from 10% to less than 2.5% in nearly 50 years, the alkalinity of the soil is increased, the soil is hardened, and the like, so that the soil fertility is obviously reduced. At present, in carbon-based organic fertilizer materials popularized in the market, carbon is an inorganic material subjected to high-temperature treatment at 500-600 ℃, and shows alkalinity, so that the carbon is difficult to be absorbed by soil, and the alkalinity of the soil is improved, and the carbon-based organic fertilizer materials are not suitable for large-area popularization. Although the content of organic matters in soil is improved by the technology of soil testing, formulated fertilization and the like popularized by governments, the content of organic matters in soil in China is still generally lower than that in foreign countries, the content of organic matters in soil needs to be improved urgently, and black land is effectively protected to ensure the grain safety in China.
In conclusion, how to effectively treat straws to improve soil organic matters is a problem to be solved by those skilled in the art.
