Abstract

The invention relates to the field of banana cultivation, in particular to a compound microbial agent for preventing and treating a banana wilt disease and a prevention and treatment method. The compound microbial agent comprises paenibacillus polymyxa, bacillus subtilis, bacillus thuringiensis, pseudomonas stutzeri, bacillus amyloliquefaciens, cold-resistant brevibacteriaceae, trichoderma and metarrhizium anisopliae. By means of a reasonable proportion, all strains are mutually influenced and promoted, and the prevention and treatment effect on the banana wilt disease is greatly improved. The prevention and treatment method of the banana wilt disease can effectively adjust the composition of bacterial colonies in soil, promote growth and propagation of probiotics and antagonistic bacteria in the soil, rapidly restore and stabilize the balance of the bacterial colonies in the soil, prevent and treat occurrence and spread of the banana wilt disease, effectively decrease the occurrence rate of the banana wilt disease and maintain the stable and high yield of bananas.

Description

technical field [0001] The invention relates to the field of banana cultivation, in particular to a compound bacterial agent and a control method for preventing and treating banana wilt. Background technique [0002] Banana is a famous tropical and subtropical fruit, which is planted in about 120 countries and regions in the world, and its annual output exceeds 100 million tons. my country is a big country of banana production and consumption. The main banana planting areas are Guangdong, Guangxi, Fujian, Hainan and Yunnan, forming a large-scale industrial structure. Banana Fusarium wilt is a devastating disease of banana production caused by Fusarium oxysporium f.sp.cubense (FOC), which is widely distributed in banana growing areas in Asia, Africa, Australia and tropical America. Under normal circumstances, Fusarium wilt diseased plants will appear within 5 months of banana planting, which will cause great damage to the seedlings. Since the disease of banana fusarium wilt...
