Composite microbial agent for rot decomposition of straw and application method thereof

Abstract

The invention relates to a composite microbial agent for the rot decomposition of straw and an application method thereof. The composite microbial agent for the rot decomposition of the straw is prepared from, by the number of effective viable bacteria, 3-30 parts of bacillus subtilis, 50-99 parts of bacillus amyloliquefaciens, 1-5 parts of trichoderma asperellum and 1-15 parts of trichoderma longibrachiatum Rifai. The application method of the composite microbial agent for the rot decomposition of the straw comprises the following steps of (1) harvesting and pulverizing the straw; (2) scattering and flat spreading the straw; (3) turning up the soil / conducting rotary tillage; (4) conducting irrigation and soaking; (5) dissolving and spraying the microbial agent; (6) 14-30 days after treatment, completing the rot decomposition of the straw. The composite microbial agent for the rot decomposition of the straw and the application method thereof have the following advantages that the rotof the straw is accelerated; the content of organic matter in the soil is increased; the pollution and fermentation barriers are reduced; the cost is reduced.

Description

technical field

[0001] The invention belongs to the biological technology of using microorganisms to treat straws, and in particular relates to a composite bacterial agent for decaying and decomposing straws and an application method thereof. Background technique

[0002] my country is rich in straw resources, with an annual total output of more than 1 billion tons. Rice straw accounts for about one-third of the total crop straw resources in the country. Air pollution losses caused by straw burning in my country are nearly 20 billion yuan every year. The resulting various environmental problems and economic losses such as smog will become more and more serious with the growth of population and the consumption of natural resources.

[0003] Straw resources are regarded as the most potential biological resources because of their characteristics of wide source, low price, renewable and degradable. The application of straw decomposing bacteria agent can quickly decompose and ...
