Method for producing biological organic fertilizer by using methane liquid as basic culture medium through fermentation

Abstract

The invention discloses a method for producing biological organic fertilizer by using methane liquid as a basic culture medium through fermentation. The method mainly comprises the following steps of: (1) preparing a fermentation medium; (2) preparing inclined bacterial strains of bacillus subtilis; (3) performing shaking culture on the inclined bacterial strains to obtain first-level seed liquid; (4) introducing the first-level seed liquid into a culture medium with SDAY to perform culture to obtain second-level seed liquid; (5) performing seed tank culture to obtain third-level seed liquid;and (6) introducing the obtained third-level seed liquid into a fermenting tank to perform amplification culture to obtain the biological organic fertilizer. In the method, the Xinjiang methane fermentation product methane liquid serves as the culture medium; and the organic fertilizer produced by fermenting in the culture medium can control soil-borne disease of commercial crops mainly comprising tomatoes and cotton, can promote growth of the economic crops, has low production cost and good effect, is applicable in Xinjiang, and is economic and practical.

Description

technical field [0001] The invention relates to a method for fermenting and producing bio-organic fertilizer using biogas slurry as a base medium, especially a method using Bacillus subtilis ( Bacillus subtilis ), as a functional microorganism, can not only control the soil-borne diseases of economic crops such as processed tomato and cotton, but also can promote the production method of bio-organic fertilizer for the growth of processed tomato and cotton, and belongs to the field of microbial technology. Background technique [0002] Xinjiang is my country's largest cotton-producing area and the production base of high-quality commercial cotton. However, after entering the 1990s, the proportion of cotton planted area in Xinjiang was too high, and the continuous cropping time was long. After 5-10 years of continuous cropping of cotton, large-scale outbreaks of diseases and insect pests such as cotton bollworm, cotton blight, and verticillium wilt are caused, and continuous c...

Problems solved by technology

At present, the fermentation production of biopesticides at home and abroad usually uses oil residue, soybean meal, corn flour, glucose and nutrients such as inorganic salts and trace amino acids, and the response surface optimization design method is used to optimize the fermentation medium. However, the production of biopesticides with these nutrients The production cost of biopesticides is still relatively high, which leads to high prices of biopesticides and limits their application and promotion.
