Problems solved by technology

[0004] However, in the traditional process, the comprehensive utilization rate of straw, especially the decomposing speed of straw is very slow. As a fertilizer, the slow decomposing speed of straw will lead to insufficient nutrient supply in the growth stage of crops on the one hand, and cause various pests to breed on the other hand. long-term damage to crops

Abstract

The invention provides a biological agent capable of effectively decomposing a rice straw. The biological agent comprises a strain culture and a carrier at the weight percentage of (20-40%):(60-80%),wherein the strain culture comprises the following various strains by weight percentage: 30-40% of bacillus subtilis, 10-20% of bacillus megatherium, 10-20% of saccharomyces cerevisiae, 5-10% of nodule bacteria, 10-20% of trichoderma viride, and 10-20% of aspergillus niger. The invention further provides a preparation method of the biological agent. The biological agent can decompose the straw, promotes the degradation of the straw, accelerates the curing speed of the straw, and increases the comprehensive use ratio of the straw.

Description

technical field [0001] The invention relates to the field of ecological agriculture, in particular to a biological preparation for effectively decomposing rice straw and a preparation method thereof. Background technique [0002] my country's annual straw resources are 840 million tons, and about 700 million tons of straw can be collected. The main varieties of straw are rice, wheat, corn, etc. Among them, about 211 million tons of rice straw, about 154 million tons of wheat straw, about 273 million tons of corn straw, and about 23 million tons of cotton straw. my country's grain production has obvious regional characteristics. The amount of straw resources in 13 major grain-producing provinces (regions) including Liaoning, Jilin, Heilongjiang, Inner Mongolia, Hebei, Henan, Hubei, Hunan, Shandong, Jiangsu, Anhui, Jiangxi, and Sichuan About 615 million tons, accounting for 73% of the national straw resources. However, the unprocessed straw left over from grain production has...
