Efficient straw-decomposing inoculant and preparation method thereof

Abstract

The invention belongs to the technical field of microorganism, in particular to a compound microbial preparation used for directly decomposing crop straws, namely an efficient straw-decomposing inoculant. The efficient straw-decomposing inoculant comprises the following raw materials by weight percentage: 20-30 percent of bacillus subtilis, 10-15 percent of white light gray streptomycete, 5-10 percent of endomycopsis fibuligera, 5-10 percent of candida utilis, 10-15 percent of aspergillus, 10-15 percent of paecilomyces lilacinus, 10-15 percent of trichoderma harzianum and 20-30 percent of thermophilus streptomycete. The efficient straw-decomposing inoculant is organically combined with soil no-tillage, shifting and fallow to achieve the comprehensive purposes of protecting the environment, improving soil, increasing the utilization rate of fertilizers, increasing the quantity and the quality of agricultural products and developing the ecological agriculture.

Description

Technical field [0001] The invention belongs to the field of microbial technology, which is specifically a composite microbial preparation for direct corruption of crop straw. Background technique [0002] How to deal with a large amount of about 700 million tons of straw every year in my country?Become an urgent real issue.At present, the four main uses of straw use: one is feed (10%-20%), the other is fuel (increasingly reduced), the third is fertilizer (the main way), and the fourth is to plant edible fungi and other raw materials (accounting for 10 10%).The potential for straw as fertilizer is the greatest. The way out is to return to the field as fertilizers. If it can be returned all of them, it will have positive significance for the cultivation of fertilizer and promoting the sustainable development of agricultural production.The use of straw to return to the field is usually: 1. Stack straw concentrated or corrupt, and then scattered into the soil.The disadvantage of thi...

Problems solved by technology

In this way, not only most of the nutrients of the straw are lost, but also the billowing smoke seriously pollutes the space on which human beings depend for survival.

[0003] At present, the problem of large-scale straw in my country is mainly solved by direct returning to the field. However, due to the high multiple cropping index in my country, the short stubble time interval, and the high carbon-to-nitrogen ratio of the straw, it is difficult to be decomposed by microorganisms in the natural state, so the straw is directly returned to the field. The cycle of microbial decomposition and transformation is long, so it is difficult to be used as a fertilizer source for seasonal crops
