Straw returning fast rot-promoting microbial inoculum

Abstract

The invention relates to a straw returning fast rot-promoting microbial inoculum, and effectively solves the problem that an existing straw returning microbial inoculum is low in degradation speed, poor in effect, high in cost and poor in usability. The straw returning fast rot-promoting microbial inoculum is prepared by mixing three of solid fermentation spore powder of Trichoderma asperellum SFC-3 and solid fermentation spore powder of aspergillus niger J4 without mutual antagonism, the solid adsorption microbial inoculum of Aspergillus nidulans QY5, the solid adsorption microbial inoculum of Rhizopus oryzae JG3, the solid adsorption microbial inoculum of Saccharomyces cerevisiae CXMJ, the solid adsorption microbial inoculum of Bacillus subtilis nkkc and the solid adsorption microbial inoculum of Bacillus amyloliquefaciens WS3-1 according to the weight ratio of 1-2: 1-2: 1: 1. The synergistic straw degradation effect of the Trichoderma asperellum SFC-3 and other strains is utilized,the carbon-nitrogen ratio is adjusted without additionally adding nitrogen sources such as urea, the practical application operation is simple and convenient, therefore, the production cost is saved,and a fermentation medium and the culture conditions are simple. The straw returning fast rot-promoting microbial inoculum is convenient to operate and easy for industrial production, and is the innovation of a straw returning technology.

Description

technical field

[0001] The invention belongs to the field of microbes, and in particular relates to a rapid decay-promoting bacteria agent for straw returning to the field.

[0002] technical background

[0003] The annual output of straw in our country is quite considerable. If it is only burned or buried in the open air, it will not only seriously pollute the environment, but also cause a lot of energy waste. Now commonly used treatment methods are physical and chemical degradation, but both have their own advantages and disadvantages, so they are not suitable for large-scale promotion. At present, microbial treatment of straw is a pollution-free and pollution-free treatment method.

[0004] When the high activity cellulase was used to treat corn stalks alone, it showed that the enzymatic hydrolysis efficiency of cellulase was very low when the straw was not pretreated, which may be related to the presence of cellulose-cellulose-lignin complex crystals in the plant cell wa...
