Abstract

The invention relates to a purpureocillium lilacinum-lactobacillus plantarum composite microbe agent. The composite microbe agent comprises a purpureocillium lilacinum microbe agent and a lactobacillus plantarum microbe agent in a weight ratio of 8-12:1. The spore concentration of the purpureocillium lilacinum microbe agent is not less than 10<9> spore / mL. The spore concentration of the lactobacillus plantarum microbe agent is not less than 15.0*10<9> cfu / mL. Through combination of the purpureocillium lilacinum and the lactobacillus plantarum, soil-borne pathogens can be inhibited, and disease resistance of plants can be improved so as to reduce harm to vegetables, thus promoting vegetable growth and reducing harms caused by root-knot nematode.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a compound microbial agent of P. lilacinus and Lactobacillus plantarum and its application. Background technique [0002] Root-knot nematode disease, also known as "tumor disease", is one of the more serious diseases that occur on vegetables. It mainly harms cucumbers, bitter melons, tomatoes, eggplants, kidney beans, celery, spinach, carrots and other common vegetables. In recent years, with the sustained and rapid development of my country's national economy, the adjustment of the vegetable industry structure, and the rapid expansion of the cultivated area of ​​vegetable protection, the occurrence of root-knot nematode is becoming more and more serious. Generally, the loss of output reaches 30-50%, and even leads to No harvest. In addition, root-knot nematode can also interact with fungi, bacteria, and viruses to form a compound infection, which aggravates th...
