Problems solved by technology

[0006] The purpose of the present invention is to provide a method for utilizing straw microorganisms to ferment and reuse, so as to solve the problem that both fungus residue and straw are commonly used raw materials for producing bio-organic fertilizers, but due to the proportion of crude fiber they contain It is difficult to decompose when fermented alone, and the fermentation time is long. Usually, mixed fermentation of raw materials is required to improve the fermentation efficiency, shorten the fermentation time and increase the nutrient content of the fermentation product. Therefore, the production cost and production process steps are increased, which is not conducive to the fermentation of fungus residue and straw. Large-scale use of biological fermentation to produce bio-organic fertilizers

Abstract

The invention discloses a method for microbial fermentation and reuse by using straws, and belongs to the technical field of straw fermentation. The method for microbial fermentation and reuse by using the straws comprises the following steps that S1 straws are smashed by using a smashing machine after drying; S2 humidity is regulated by water; S3 mixed fermentation of a microbial straw fermentation agent and cellulase is carried out; S4 a fermenting tank is filled with two segments of fermentation; and S5 liquid state organic fertilizers and solid state organic fertilizers are obtained. A method of microbial fermentation straw returning to a field is used, straw degradation is carried out by using the fermentation of the straw fermentation agent and the cellulase, the fermentation degradation rate is greatly accelerated, so that the straws are fermented to the liquid state organic fertilizers and solid state organic fertilizers, direct returning to the field and fertilization is carried out, environmental pollution caused by straw waste can be reduced, the fermentation time can be shortened, causative agents such as worm eggs and bacteria carrying bodies are thoroughly killed, degraded soil can be restored, the development of green agriculture is facilitated, and the sustainable development of the agriculture is promoted.

Description

technical field [0001] The invention relates to the technical field of straw fermentation, in particular to a method for utilizing straw microorganisms to ferment and reuse. Background technique [0002] With the improvement of farmers' living standards and the development of science and technology, it is no longer necessary to burn straw for cooking and boiling water, etc. Straw has become a kind of agricultural waste, and straw is generally burned on the spot and returned to the field, which not only wastes resources, but also seriously pollutes Air, reasonable straw returning to the field can increase soil organic matter, improve soil structure, loosen the soil, increase porosity, reduce capacity, and promote microbial activity and crop root development. It will also lead to the increase of soil pathogens, aggravation of crop diseases, lack of seedlings, stiff seedlings and other adverse phenomena. Therefore, only by adopting reasonable measures of returning straw to the ...
