Straw decomposition agent

Abstract

The invention discloses a straw decomposition agent. An active ingredient of the straw decomposition agent is prepared from actinomycetes, trichoderma harzianum, saccharomyces and bacillus subtilis which are in the bacterial flora formation unit number ratio of (0.5 to 2): (1 to 2): (0.8 to 1.2): 1. According to the straw decomposition agent disclosed by the invention, all bacterial florae can harmoniously coexist and mutually promote so as to achieve the effect of having complementary advantages, and lignin, cellulose, hemicellulose and the like in crop straws can be effectively decomposed; the degradation time is short, the decomposition effect is stable, diseases and insect pests are eliminated effectively, and the straw decomposition agent has a decomposition effect at normal temperatures, so that the rapid treatment of organic materials and final resource-converting utilization are achieved; treated organic solid wastes are transformed thoroughly, embody good properties of improving soil, promoting growth and inhibiting soil-borne diseases and meanwhile are environmentally friendly and sanitary.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a straw decomposing agent. Background technique [0002] At present, due to the excessive use of chemical fertilizers in rural areas of our country, the soil organic matter and beneficial microbial flora and quantity have decreased, and the physical and chemical conditions of the soil have deteriorated seriously, which will inevitably affect the sustainable development of agriculture and the deterioration of the ecological environment. To this end, the country has adopted a series of policies aimed at improving soil organic matter, improving soil, and reducing environmental pollution, and invested a lot of manpower, material resources, and financial resources to improve the above conditions. [0003] my country is rich in straw resources, with an annual output of about 800 million tons, part of which is used to return straw to improve soil quality and increase crop yields. Since crop s...

Problems solved by technology

These straw decomposing agents take a long time to start decomposing straw, which takes more than 14 days. The decomposition effect is unstable, and high temperature is required to decompose straw, which is difficult to meet the needs of agricultural production.
