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 technical field of microbes, in particular to a compound microbial preparation for directly decomposing crop stalks. Background technique [0002] my country produces a large amount of about 700 million tons of straw every year, how to deal with it? become an urgent real problem. At present, there are four main uses of straw utilization: one is feed (accounting for 10%-20%), the other is fuel (decreasing), the third is fertilizer (the most important way), and the fourth is planting edible fungi and other raw materials (accounting for 10%) %). Straw has the greatest potential as fertilizer, and the way out is to return it to the field as fertilizer. If all of it can be returned to the field, it will have positive significance for fertilizing the soil and promoting the sustainable development of agricultural production. The methods of returning straw to the field are usually: 1. Put the straw in a concentrated stack or ret...

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
