Abstract

The invention relates to the field of biotechnology, in particular to a straw decomposing agent and preparation and application thereof. The straw decomposing agent comprises a composite microbial agent I and a composite microbial agent II, the composite microbial agent I can effectively decompose pectin, a polysaccharide-polysaccharide composite and a lignin polysaccharide composite existing in straw cell walls into free polysaccharide, the degree and speed of the decomposing is further increased, the preparation method of the straw decomposing agent is simple and practical, the activity of the microbial agent is good, the enzyme production is high, a prepared straw organic fertilizer is rich in nutrients, the soil condition is effectively improved, the regeneration speed is fast, the preparation method includes pretreatment, a fermentation step I and a fermentation step II, combined with decomposing fermentation, the decomposing degree and speed of the straw organic fertilizer is effectively improved, and the practicability is good.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a straw decomposing agent and its preparation and application. Background technique [0002] Straw refers to the remaining stems and leaves of gramineous crops such as rice, wheat, and corn after threshing. China has abundant material resources of crop straw. The traditional incineration method not only wastes a lot of cellulose resources, but also causes serious environmental damage. Pollution. In recent years, in order to make rational use of cellulose resources, more and more technical means have been applied to the treatment of straw. Among them, the use of straw returning technology to convert crop straw into organic fertilizer can realize the reduction of substances in the farmland ecosystem. It is an important measure to realize the sustainable development of agriculture and the construction of rural ecological environment in my country. [0003] However, straw returning to the...
