Compound microbial agent for treating organic wastes of livestock and poultry

Abstract

The invention discloses a compound microbial agent for treating organic wastes of livestock and poultry, and relates to the technical field of microorganisms. The composite microbial agent comprises amicrobial agent and a solid carrier, wherein the microbial agent comprises bacillus megatherium, azotobacter vinelandii, bacillus mucilaginosus, thermococcus, aspergillus oryzae and trichoderma longibrachiatum; the solid carrier is a prolactan polysaccharide/halloysite composite microsphere. According to the compound microbial agent disclosed by the invention, a plurality of microorganisms with complementary and synergistic functions are mixed and inoculated to a solid carrier, so that the quantity and activity of the microorganisms can be increased, the mineralization degradation degree of the compound microbial agent on organic wastes in an aerobic composting process is enhanced, and the composting effect is improved. Meanwhile, emission of harmful gas can be reduced, and retention of nitrogen is promoted.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a compound microbial bacterial agent for treating organic waste of livestock and poultry. Background technique [0002] China has a long history of agriculture and animal husbandry, and is one of the earliest livestock and poultry breeding industries in the world. The development of livestock and poultry breeding industry has solved food quality and safety problems for the country, improved the diet structure of our people, and occupies an indispensable position in the economic structure. Although the development momentum of the livestock and poultry breeding industry is promising, there are still many practical problems in the production process of the industry, the most prominent of which is the environmental pollution problem of the industry. [0003] The main source of pollution in the livestock and poultry breeding industry comes from the livestock and po...

AI Technical Summary

Problems solved by technology

[0003] The main source of pollution in the livestock and poultry breeding industry comes from the livestock and poultry manure produced in the production process. If it is not treated effectively, it will not only cause environmental pollution, disease transmission and other hazards, but also hinder the effective use of livestock and poultry manure and the sustainable development of animal husbandry.

Livestock and poultry manure is rich in organic matter and is a good fertilizer. However, direct application of untreated livestock and poultry manure will cause diseases and insect pests, heat production from fermentation will cause burnt seedlings, produce harmful gases to crops and the environment, and cause soil oxygen deficiency and other hazards.
