Abstract

The invention belongs to the technical field of microbe application and discloses a microbial agent for promoting quick decomposition of agricultural wastes, prepared from the following steps of respectively carrying out first stage amplification culture and second stage amplification culture on four microbes which are bacillus subtilis, micromonospora streptomyces, trichoderma koningii and chaetomium globosum, and respectively obtaining four liquid cultures of the microbes; then commonly inoculating the four liquid cultures in a carrier culture medium according to a ratio with the inoculation amount of 0.2 percent, controlling the moisture content at 55-60 percent, culturing for 7 days at a constant temperature of 28 DEG C; and finally, carrying out low-temperature drying treatment on a complex bacteria subjected to culturing at the temperature of 35-40 DEG C, and carrying out live bacteria detection. The microorganism composting microbial agent can promote quick decomposition of agricultural waste aerobic composts, has remarkable action of eliminating malodorous gas generated by organic wastes and also reduces the nutrient loss caused by volatilization in a composting process.

Description

technical field

[0001] The invention belongs to the technical field of applied microorganisms, and in particular relates to a microbial bacterial agent capable of promoting rapid decomposition of agricultural waste such as pig manure, chicken manure and wheat straw, and a preparation method thereof. Background technique

[0002] With the rapid development of modern agriculture, especially the large-scale and intensive production of animal husbandry, large-scale centralized disposal of agricultural waste such as livestock and poultry manure has resulted. These organic wastes contain a large number of pathogenic microorganisms and parasite eggs , a large amount of malodorous gas will be produced during the disposal process, mainly including ammonia, hydrogen sulfide, indole, mercaptan, sulfide, formaldehyde, acetaldehyde, acrolein, methylamine, ethylamine, phenol, thiophenol and volatile Fatty acids, etc., pollute the human living environment and seriously endanger the health ...
