Composite microbial system for quickly degrading maize straw and preparation and pretreatment method thereof

Abstract

The invention discloses a composite microbial system for quickly degrading maize straw, a preparation method thereof and a pretreatment method for conducting quick maize straw degrading through the composite microbial system. The component of composite microbial system for quickly degrading the maize straw is an optimal combination of fungus, bacteria and actinomycetes, the composition is more diversified, and accordingly the composite microbial system has a better degrading effect on the maize straw. Through the pretreatment method adopting the composite microbial system to pretreat the maize straw, the microstructure of the maize straw is damaged, the hydrolysis process is accelerated, and the accessibility of lignocelluloses is remarkably improved, so that the straw degrading efficiency and stability are improved notably, and resource utilization of the maize straw is further facilitated.

Description

technical field [0001] The invention relates to the technical field of microbial screening methods, in particular to a composite bacterial strain for rapidly degrading corn stalks, a preparation method thereof, and a pretreatment method for rapidly degrading straw by using the composite bacterial strain. Background technique [0002] my country is a large agricultural country, and various crop straw resources are very rich, and crop straw is mainly composed of cellulose, hemicellulose and lignin. The cycle of microbial decomposition and transformation is long, so it is difficult to be used as a fertilizer source for seasonal crops. In the past, most of the straw was burned by farmers as fuel when there was a shortage of energy and fuelwood in rural areas. However, with the development of the rural economy and the resolution of rural energy problems, straw is no longer used as fuel, and the phenomenon of concentrated burning of crop straw during the harvest season has become ...
