Compound microbial agent for preventing and treating diseases and application thereof

Abstract

The invention discloses a compound microbial agent for preventing and treating diseases and application thereof, and relates to the technical field of microbial agents. The compound microbial agent comprises the following components: bacillus subtilis, bacillus licheniformis, rhodobacillus palustris, bacillus mucilaginosus, bifidobacterium, phanerochaete chrysosporium, lactic acid bacteria, streptomyces jingyangensis, a stabilizer, chitosan modified bentonite, trace elements and potassium fulvate. The prepared microbial agent in the invention can effectively prevent and treat plant root diseases, has a very prominent prevention and treatment effect, and can be widely applied to agricultural production; and a bio-organic fertilizer prepared by using the complex microbial agent can condition soil, activate the activity rate of microorganisms in the soil, overcome soil hardening and increase the air permeability of the soil, has a prevention and treatment effect on various fungal diseases and bacterial diseases, and has an inhibition effect on viral diseases.

Description

technical field

[0001] The invention relates to the technical field of microbial bacterial agents, in particular to a compound microbial bacterial agent for preventing and controlling diseases and its application. Background technique

[0002] Plant diseases are one of the important factors restricting the high quality and high yield of crops. It is estimated that the average loss of major crops in the world accounts for 10%-15% of the total output, and the annual direct economic loss is as high as hundreds of billions of dollars. Plant diseases not only directly cause the decline of crop yield and quality, but also some pathogenic bacteria can secrete a variety of toxins and metabolites harmful to humans and animals during the process of infecting crops, which poses a great threat to the safety of agricultural products. Among various crop diseases, plant root disease has always been a headache for farmers. The occurrence of root disease will directly cause serious problems...
