Compound microbial inoculum resistant to high-temperature decomposition for crop straws and preparation method thereof

Abstract

The invention relates to a fermentation microbial inoculum, in particular to a compound microbial inoculum resistant to high-temperature decomposition for crop straws and a preparation method thereof.The composite microbial inoculum comprises YM bacteria, bacillus licheniformis, alcaligenes, agaricus bisporus, bordetella, streptomyces, coccidioides immitis, aspergillus flavus and trichoderma koningii. The components are evenly mixed in proportion to obtain a final product. The compound microbial inoculum provided by the invention can rapidly decompose crop straws and shorten the time for decomposing the straws; in the prior art, the time for decomposing the straws is generally more than 10 days; through the treatment with the compound microbial inoculum resistant to ultra-high temperaturedecomposition, straws can be decomposed and returned to the field within 7 days, and the time interval between postharvest and planting is shortened; and a fermentation process has no odor and fullykills pathogenic bacteria and pathogenic microorganisms.

Description

technical field [0001] The invention relates to a fermentation bacterial agent, in particular to a high-temperature-resistant composite bacterial agent for decomposing crop straw and a preparation method thereof. Background technique [0002] Crop straw has the characteristics of rich resources, wide sources, low resource utilization rate, and great research and development potential, so its resource utilization has become one of the hotspots of scientific research. Crop stalks have a large quantity, variety and wide distribution. The annual output of straw in the world is more than 3.1 billion tons. my country is a big grain producer and also a big straw producer. It can produce more than 900 million tons of straw every year, accounting for about 20% to 30% of the total straw in the world. Among them, rice, wheat, About 580 million tons of soybean, corn, potato and other food crop straw. Accounting for 89% of the total straw; peanut, rapeseed, sesame, sunflower and other o...

AI Technical Summary

Problems solved by technology

[0005] More and more people are paying attention to straw quick rot agents. After development and research in recent years, there are more and more brands and types of straw quick rot agents on the market, but there are some problems and problems. limitation

For example, the cost of use is high, and the bacteria agent cannot withstand high temperature, so it is necessary to control the low temperature and prolong the fermentation time during fermentation, etc.
