Organic material decomposition agent and preparation method thereof

Abstract

The invention relates to an organic material decomposition agent and a preparation method thereof. The organic material decomposition agent is prepared from the following components in parts by weight: 8-12 parts of strain A and 0.5-2 parts of strain B, wherein the strain A is prepared from the following components in parts by weight: 40-55 parts of bacillus subtilis, 25-35 parts of lactic acid bacteria, 7-13 parts of flavobacteria, 1-5 parts of rhizopus oryzae and 3-8 parts of aspergillus niger; the strain B is prepared from the following components in parts by weight: 0.5-1.5 parts of pichia pastoris and 1-1.5 parts of rhodotorula. The organic material decomposition agent contains various beneficial microorganisms which are matched with each other and are strong in symbiosis; the organic material decomposition agent pays more attention to substance transformation while effectively decomposing organisms, not only can accelerate the decomposition of non-degradable substances such as pectin, cellulose, lignin and the like, but also can ensure the contents of nitrogen, phosphorus and potassium in an organic fertilizer, and furthermore, the composting effect is improved and the quality of a composted finished product is improved; in addition, the organic material decomposition agent has the advantages of low price, wide application range, strong practicability and convenience in popularization.

Description

technical field [0001] The invention belongs to the technical field of environmental microorganisms, and in particular relates to a decomposing agent, in particular to an organic material decomposing agent and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the problems of straw burning and livestock and poultry manure brought about by the rapid development of agriculture; the organic waste (bagasse, pomace, cake, distiller's grains, bran, Starch sludge) problem; urban domestic garbage problem; domestic sludge problem generated in urban domestic sewage treatment; has become a major problem that endangers human survival and social development. Solving the way out of these organic wastes and protecting the environment are urgent problems to be solved at present. The current solutions are generally incineration, landfill, and comprehensive utilization. Due to ser...

Problems solved by technology

Such as Japan's BYM bacterium, EM bacterium, South Korea's Promised Land bacteria etc. also have application in my country, but price is higher, function is single, and liquid application is inconvenient, and popularization is restricted; Fermentation Method" (CN 200410072694.6) discloses a rapid microbial fermentation agent for chicken manure, which is composed of Trichoderma viride, actinomycetes, photosynthetic bacteria, thermophilic microorganisms, thermobacillus, yeast, and bacillus licheniformis ; The literature patent "Method for Producing Commodity Organic Fertilizer by Rapidly Fermenting Pig Manure Using Microorganisms" (CN200710079090.8) proposes a fermenting bacteria composed of Bacillus, Lactobacillus, photosynthetic bacteria, nitrogen-fixing bacteria, yeast, filamentous fungi, etc. agent; the patent document "Fermentation agent for agricultural waste treatment and its preparation method" (200410039818.0) discloses two new strains of yeast ZJY2 and Streptomyces luteus W1 and another known Bacillus cereus ME1-2

However, at present, these artificially added bacterial agents are either too specific and only have obvious effects on a single type of waste; or lack of pertinence, different compost raw materials use the same preparation, after inoculating different compost raw materials, The microbial community in the fermentation agent has poor adaptability, a large amount of beneficial microbial resources are lost, and the fermentation efficiency is reduced; or too many strains are used, no dominant strains are formed in the ratio of the agent, and production is difficult, which affects its application effect

At present, most research reports place too much emphasis on the effect of the inoculum on the composting results in the laboratory, or the practicability of the inoculum is not strong due to the small number of bacteria, or the promotion of the inoculum is hindered because the inoculum comes from abroad and the price is high
