Multiple-effect microbial fertilizer prepared by three strains of bacillus licheniformis

Abstract

The invention discloses a multiple-effect microbial fertilizer prepared by three strains of bacillus licheniformis. The fertilizer is prepared from the following steps of: performing three-level liquid fermentation on the three strains of bacillus licheniformis so as to reach tanking standard respectively; and mixing and processing the fermentation liquor obtained by fermenting the three strains of bacillus licheniformis. The three strains of bacillus licheniformis are a bacillus licheniformis BL-1 CGMCC No.1009 strain, a bacillus licheniformis BL-8 CGMCC No.3925 strain and a bacillus licheniformis BL-816 CGMCC No.1379 strain. The multiple-effect microbial fertilizer has the advantages of high viable bacteria content, excellent effects of accelerating growth and production increase and preventing insects and diseases on wheat, corn, rice and other crops, fast propagation and strong adaptability of the viable bacteria in soil, and capacities of effectively controlling soil-borne diseases and insect damage, improving the soil fertility and improving the sugar content of melons and vegetables.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a multi-effect microbial fertilizer produced by three strains of Bacillus licheniformis. Background technique [0002] With the improvement of people's living standards, the safety and quality of agricultural products have received unprecedented attention. Biological control of plant diseases and insect pests and yield increase have always been the two major concerns of crop growth. In recent years, with the rapid expansion of vegetable planting area in greenhouses and greenhouses, the occurrence of downy mildew, fusarium wilt, root-knot nematode and other diseases and insect pests has increased year by year. Cucumber downy mildew is a frequent and serious disease in cucumber production, commonly known as "horse racing disease". Under the environment suitable for the disease, the disease develops very fast, and the plant can die within ten days, generally reducing yield by 2...

AI Technical Summary

Problems solved by technology

[0004] So far, no agriculturally acceptable low-cost multi-effect microbial fertilizer has been developed at home and abroad that has multiple functions of insect control, disease prevention, growth promotion, production increase, and fruit quality improvement, and can maintain ecological balance at the same time.
