Abstract

The invention relates to the technical field of biological control, in particular to a compound microbial agent as well as a preparation method and application thereof. The compound microbial agent comprises a microbial agent and a protective agent, wherein the microbial agent comprises paenibacillus polymyxa, bacillus amyloliquefaciens, bifidobacterium bifidum, paecilomyces fumosoroseus, beauveria bassiana and lactobacillus helveticus; the protective agent comprises corn flour, brown sugar, ammonium sulfate, monopotassium phosphate and magnesium sulfate heptahydrate; the compound microbial agent disclosed by the invention can improve the soil microenvironment, and can effectively prevent and treat wildfire diseases in the tobacco field production process.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a composite microbial agent and its preparation method and application. Background technique [0002] China is the largest tobacco producer in the world today, and the total output and sales of tobacco leaves account for about 30% of the world. At present, tobacco tax has accounted for 1 / 10 of my country's fiscal revenue, and tobacco has become an important economic crop in my country. With the change of cultivation conditions, tobacco pests and diseases are increasingly harmful to tobacco production, causing huge economic losses. According to incomplete statistics, the direct economic loss caused by diseases in the process of tobacco planting in my country is more than 700 million yuan every year. Due to the extensive use of chemical pesticides, the residues of chemical pesticides in tobacco leaves have increased, and the resistance of diseases has increased and bec...
