Problems solved by technology

[0004] At present, there are many technologies and products related to decomposing bacteria agents, but most of them have the following problems: First, the fermentation efficiency is not high
The performance is slow start, slow deodorization, large amount of addition, and long fermentation cycle
Second, it is not resistant to low temperature
Most of the strains used are medium-temperature, suitable for use at an ambient temperature above 20°C. If the temperature is low, the fermentation will take a long time to start or will not ferment, and it will be difficult to carry out fermentation production in winter
Three is a single purpose
Most of them are only used for livestock and poultry manure fermentation or straw fermentation, resulting in high R&D and production costs
The main reasons for the above-mentioned problems are: firstly, the composition of the strains of the starter is unreasonable, and some strains are simple combinations without considering the functional complementarity and mutual symbiosis between the constituent strains, resulting in low fermentation efficiency, especially at low temperature. slow or no fermentation
Second, the composition of the strain is a simple combination with a single function
[0007] The applicant has not seen any literature reports similar to the technical solutions and technical effects of the present application in the prior art

Abstract

The invention belongs to the preparation of a microbial decomposing agent, in particular to a microbial decomposing agent and its preparation and application in the fermentation and decomposing of organic materials. The composite original bacterial powder is made from Wickerhamomyces anomalus CGMCC No.20654 and Rhizopus oryzae CGMCC No.3.5085, and the microbial decomposing agent is made by mixing the composite original bacterial powder with organic material carriers and inorganic carriers. The invention solves the problems in the prior art that the strain starts slowly or does not start at low temperature, has single use, and the like. The method can be started at an ambient temperature of 15° C., effectively decomposes and degrades crop stalks and livestock and poultry manure, and has a fast decomposing speed and a simple preparation method.

Description

technical field [0001] The invention belongs to the preparation of a microbial decomposing agent, in particular to a microbial decomposing agent that can be started at a lower ambient temperature, and its preparation and application in the fermentation and decomposing of organic materials. Background technique [0002] A large amount of organic waste will be produced in aquaculture, planting, sewage purification, food processing, pharmaceutical and other industries. Improper handling will lead to pollution of the surrounding environment, groundwater and farmland, and adversely affect production, life and people's health. Using high-temperature aerobic fermentation technology, it can generate a large amount of biological heat, kill the eggs, pathogenic bacteria, grass seeds, etc., and at the same time convert macromolecular organic matter such as cellulose, lignin, and protein into humus, amino acids, etc., and release nitrogen. Phosphorus, potassium and medium and trace elem...
