Preparing method of efficient straw decomposition agent

Abstract

The invention discloses a preparing method of an efficient straw decomposition agent, and belongs to the technical field of decomposition agent preparation. The preparing method includes the steps that thalli in rotted wood where mushroom grows are selected, enrichment culture is carried out on the thalli to obtain bacterium liquid, trichoderma atroviride microbial inoculum, bacillus subtilis microbial inoculum, saccharomyces cerevisiae microbial inoculum and bacillus thuringiensis microbial inoculum are activated on a slope, fermentation media are inoculated with the microbial inoculums and fermentation culture is performed respectively, all strain fermentation liquids are mixed to obtain a mixed fermentation liquid, the mixed fermentation liquid and the bacterium liquid are mixed and then concentrated, and an adsorbing carrier and the concentrated liquid are mixed to prepare the efficient decomposition agent. The prepared straw decomposition agent is high in decomposition speed and capable of completely degrading straw, promoting release of straw nutrient, improving the fertility improvement effect of soil with straw returning and improving the biological effect.

Description

technical field [0001] The invention discloses a preparation method of a high-efficiency straw decomposing agent and belongs to the technical field of decomposing agent preparation. Background technique [0002] The annual output of crop straw in China is about 700 million tons, and it is one of the countries with abundant straw resources. For a long time, straw has not been effectively utilized as a resource, and a large amount of straw has been discarded and burned, which not only leads to a large waste of organic matter and nutrient resources, but also And it will cause serious environmental pollution. Most agricultural developed countries in the world attach great importance to the combination of land use and nutrition and the development of ecological agriculture. Straw returning and farmyard manure account for 2 / 3 of the total amount of fertilization. Therefore, straw returning, as an advanced conservation tillage technology, is widely used in All agricultural develop...

Problems solved by technology

[0006] The technical problem mainly solved by the present invention: A large amount of rice stalks are present in our country, which brings many problems. In the mechanized returning of the full amount of rice stalks to the field, the amount of rice stalks is large, the efficiency of returning to the field is slow, and the rice stalks are not easily degraded. , thus leading to the problems of seedling emergence, soil preparation and seedling growth that are prone to hypoxia, and a method for preparing a high-efficiency straw decomposing agent is provided. Then inoculate the fermented medium into the fermentation medium after activation of Trichoderma dark viridis agent, Bacillus subtilis agent, Saccharomyces cerevisiae agent and Bacillus thuringiensis agent respectively on a slant surface, and mix the fermented liquids of various strains to obtain a mixed fermented liquid, and After mixing with the bacterial liquid and then concentrating, the prepared adsorption carrier is mixed with the concentrated solution to prepare a high-efficiency straw decomposing agent. The straw decomposing agent prepared by the present invention has a fast decomposition rate, can completely degrade straw, and can promote the release of straw nutrients. , Enhance the soil fertilizer effect of straw returning to the field, and improve the biological effect
