Compound microbial agent preventing continuous cropping disease

Abstract

The invention provides a compound microbial agent preventing continuous cropping disease. The compound microbial agent is prepared from the following raw materials in parts by weight: 40-50 parts of amicrobe composition, 20-25 parts of tobacco residues, 10-15 parts of humic acid, 5-10 parts of plant ash, 3-6 parts of a boron-magnesium fertilizer and 1-3 parts of trace elements. The microbe composition is prepared by mixing Bacillus licheniformis, Beijerinckia indica, Bacillus thuringiensis, Paecilomyces lilacinus and Bacillus mucilaginosus according to a mass ratio of (3-4):(2-3):(2-3):(1-2):(1-2). The compound microbial agent is prepared by uniformly mixing the microbe composition, the tobacco residues, the humic acid, the plant ash, the boron-magnesium fertilizer and the trace elementsaccording to the ratio, adding water, uniformly mixing the mixture until the mixture contains water and water in the mixture does not drop when the mixture is tightly held in a hand, putting the mixedmicrobial agent into a greenhouse for fermentation at 37 DEG C for 3-5 days, turning over the mixture for 1-3 times every day, and stacking the mixture for 2-4 days for fermentation until the temperature is 40-45 DEG C to obtain a final product. The compound microbial agent has a good synergistic effect and an excellent continuous cropping disease prevention effect, and especially can solve the problems of frequent occurrence of disease and pests and pathogenic bacteria, reduction of quality and yields, lack of organic matters and trace elements and the like in the growth of crops.

Description

technical field [0001] The invention relates to a method for regulating soil structure through a compound microbial agent to prevent heavy cropping, and specifically refers to a method suitable for regulating crop heavy cropping plots, and using a compound microbial agent to adjust soil structure to prevent heavy cropping. Background technique [0002] Heavy cropping disease is a complex problem that plagues sustainable agricultural production. It has been reported that the aggravation of soil fungal diseases, autotoxicity, increase in nematodes, one-sided absorption of soil nutrients by crops, and deterioration of soil physical and chemical properties are the main reasons for heavy cropping disease. However, the root cause is the deterioration of the soil micro-ecological environment. Continuous cropping changes the microbial ecological environment in the rhizosphere of crops to a direction that is conducive to the increase of the number of pathogenic species and the reducti...

Problems solved by technology

[0004] However, in farmlands suffering from heavy stubble disease, in addition to the imbalance of soil nutrition and the accumulation of pathogenic bacteria of this crop caused by single planting of one crop for many years, there are also toxins produced by the decomposition of crop residues, such as organic acids, aldehydes, alcohols, Hydrocarbons, etc. cause self-toxicity, affecting the growth of crops themselves
