Straw microorganism decomposing bacterial agent and preparation method thereof

Abstract

The present invention relates to a straw microorganism decomposing bacterial agent, which is prepared mainly from a straw microorganism decomposing bacterial liquid and a protein nutrition agent according to a volume ratio of 1:1, wherein the straw microorganism decomposing bacterial liquid preparation method comprises: carrying out sealed fermentation on a straw mixture to obtain bacteria, and carrying out in vitro culture on the bacteria by using a microorganism culture medium to obtain the straw microorganism decomposing bacterial liquid. According to the present invention, the composting heat generation bacteria are obtained by using the straw mixture fermentation process, and are subjected to enrichment culture, the obtained composting heat generation bacteria are mixed with the protein-rich protein nutrition agent to obtain the straw microorganism decomposing bacterial agent; the obtained straw microorganism decomposing bacterial agent can produce the heat during the straw composting process so as to effectively supply the temperature required by bacterial breeding; and the protein nutrition agent supplies the nitrogen source, such that a lot of the microorganism can be bred by using the nitrogen source supplied by the protein nutrition agent at the early microorganism fermentation stage so as to improve the compositing rate, effectively shorten the time required by the fertilization, and solve the problems of less functional microorganism, slow breeding and serious nitrogen loss at the early fertilization stage in the fertile soil fertilization process using the straw composting fertilizer.

Description

technical field [0001] The invention belongs to the technical field of soil fertilization, and in particular relates to a straw microbial decomposing bacterial agent and a preparation method thereof. Background technique [0002] With the continuous growth of my country's economy, the rapid expansion of urban construction, the acceleration of urban-rural integration and the major adjustment of industrial structure, a large loss of cultivated land resources has been caused, and the per capita cultivated land area has been decreasing year by year. threaten. In addition, soil erosion, land pollution, soil desertification, and salinization have further intensified, causing damage to the fragile land ecological environment and degrading the quality of cultivated land. In land development and consolidation, its main objects are wasteland, tidal flats, field ridges, abandoned homesteads, saline-alkali land, wind-blown sandy land, and barren land that has been destroyed and abandone...

AI Technical Summary

Problems solved by technology

However, in the existing improved fertilization process, traditional composting will lead to problems such as few functional microorganisms in the early stage of fertilization, slow reproduction speed, serious nitrogen loss, easy to produce odor, low degree of harmlessness, and unstable fertility. In the process of straw composting, due to the low nitrogen content of straw, the rapid reproduction of decomposing bacteria is limited. Therefore, it is particularly important to cultivate and screen microorganisms that can accelerate the decomposing rate in straw, and then prepare bacterial agents and fertilize them to improve barren soil.
