Background
With the increasing year by year of food yield in China, the yield of crop straws is also increased year by year, the annual yield of the crop straws in China exceeds 10 hundred million tons, and the crop straws become one of the most abundant substances in the world, the comprehensive utilization rate of the straws in China is about 80 percent, and the crop straws are mainly applied to straw returning, livestock and poultry feeds, biomass energy, light industrial raw materials and the like, but part of the straws are directly burnt or discarded. A great deal of dense smoke is generated, and the living environment and the transportation of people are seriously influenced. Incineration poses a serious environmental problem, and governments have mandated prohibition on incineration of straw. The direct returning of the straws to the field can cause the adverse phenomena of increase of soil germs, aggravation of crop diseases, seedling shortage and the like, and is not beneficial to the growth of crops in the next season.
In order to improve the utilization rate of the straws, the method for producing the organic fertilizer by composting and fermenting the plant straws by using the plant fermentation principle is a good choice. The compost can change the straws into valuable things, and is increasingly applied to the field by people. However, the traditional composting method adopts open-air composting, and has the defects that the occupied area of the composting is large, the compost pile needs to be turned in the composting process, time and labor are wasted, the compost pile is difficult to move, the odor generated by the composting affects the environment and the like. In the straw composting process, although the straws are rich in organic matters and some nutrients, because the available nutrients are insufficient and the C/N ratio is too high, compost microorganisms are difficult to obtain the nutrients suitable for the growth of the straws in a short time, so that the compost microorganisms quickly decompose the straws.
