Method for determining fermentation capability of functional microbial carrier

Abstract

The invention discloses a method for determining the fermentation capability of a functional microbial carrier. The method comprises the following steps that 1, a functional strain is inoculated to anorganic fertilizer carrier, and a functional bio-organic fertilizer for use is obtained through fermentation; 2, the distinctive carbon and nitrogen sources of the functional strain and the functional bio-organic fertilizer are determined, the area of the carbon and nitrogen sources which can be metabolized by the functional strain is used for reference and is marked with a red color, the area ofthe carbon and nitrogen sources which can be metabolized by the functional bio-organic fertilizer is used for detection and is marked with a green color, and the area of the carbon and nitrogen sources, having the same capacity, of the functional strain and the functional bio-organic fertilizer are marked with a yellow color; 3, the fermentation capability of an organic fertilizer carrier is calculated. According to the method, by comparing the difference between the distinctive carbon and nitrogen sources of functional microbes and the distinctive carbon and nitrogen sources of the fermentedbio-organic fertilizer, the fermentation capability of the microbial carrier can be quickly determined, thus the best carrier for fermentation of the functional microbes can be quickly determined, and the screening efficiency of the functional microbial fermentation carrier is greatly improved.

Description

technical field [0001] The invention relates to functional microorganisms, in particular to a method for measuring the fermentation capacity of functional microorganism carriers. Background technique [0002] At present, the main problems facing my country's soil are: slow transformation of soil nutrients, accumulation of soil pollutants and frequent occurrence of soil-borne diseases. The application of organic fertilizers, especially bio-organic fertilizers with special functions, has become a new idea for repairing soil in tobacco fields and preventing various soil-borne diseases and continuous cropping obstacles. However, functional strains are not easy to colonize when applied alone in the soil. Inoculating them in suitable organic fertilizers for secondary solid fermentation to make functional bio-organic fertilizers can improve the colonization ability of functional strains in soil and rhizosphere , so as to achieve the purpose of regulating soil microecology, improvi...
