Method for preparing straw-decomposing inoculant capable of inhibiting soil-borne diseases

Abstract

The invention discloses a method for preparing a straw-decomposing inoculant capable of inhibiting soil-borne diseases. The straw-decomposing inoculant capable is characterized by being prepared by compounding aspergillus nidulans with fibrinolysis function, aspergillus oryzae, bacillus subtilis, yeast and bacillus pumillus solid with biological control function. The product can be used for effectively accelerating the decomposing speed of returned straws, inhibiting growth of rice sheath blight disease, rice blast, wheat sharp eyespot and other pathogenic bacteria. When the straw-decomposing inoculant is applied to the field, the straw decomposing speed can be accelerated, the weight loss ratio of straws can be remarkably increased, and the straw tensile force can be remarkably reduced; the number of pathogenic bacterium antagonistic bacillus in the soil can be increased, and the number of pathogenic microbes can be remarkably reduced.

Description

technical field [0001] The patent of the invention relates to a straw decomposing agent capable of inhibiting soil-borne diseases and a preparation method thereof, belonging to the technical field of agricultural microorganism application. Background technique [0002] The annual output of straw in my country is about 1 billion tons. The main component of straw is cellulose polysaccharide, and secondly, it also contains nitrogen, phosphorus, potassium and other elements needed by plants. After the straw rots, it can increase the number of soil organic matter and soil aggregates of different sizes, thereby increasing soil permeability and water holding capacity, and reducing soil compaction; cellulose decomposition can provide energy for microbial reproduction, thereby increasing the number and diversity of soil microorganisms. Increase the ability of soil organic matter conversion and energy transfer to improve soil quality. [0003] With the massive transfer of rural labor...

AI Technical Summary

Problems solved by technology

However, many decomposing agents cannot inhibit pathogenic bacteria, and growers are worried about the spread of diseases, so they will remove the straw from the farmland and pile it on the head of the field. After the straw rots, a large amount of sewage will enter the natural water body with the drainage of the farmland and natural precipitation, causing water pollution.
