Abstract

The invention relates to a microbial agent for soil improvement and a preparation method thereof, comprising the following steps: fermenting Paenibacillus polymyxa strains to obtain a first fermentation liquid; adsorbing the first fermentation liquid to an adsorption carrier to obtain a second fermentation liquid A mixture; fermenting the strains of Bacillus pumilus to obtain a second fermentation liquid; adsorbing the second fermentation liquid on an adsorption carrier to obtain a second mixture; mixing the first mixture with the second mixture to obtain soil The special microbial bacterial agent for improvement is applied to the diseased and secondary salinized soil to cultivate crops. The special microbial agent for soil improvement of the present invention has the functions of restoring soil micro-ecological balance, improving soil fertility and improving the quality of agricultural products; it can also reduce the amount of fertilizer application, effectively improve the utilization rate of fertilizer, and improve the quality and economic benefits of crops .

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a special microbial agent for soil improvement and a preparation method thereof. Background technique [0002] Soil is the basis for the production of high-quality agricultural products, and the balance and health of the soil micro-ecological environment directly affect the improvement of the quality of agricultural products. Due to the huge variety and number of microorganisms in soil, and the complex and changeable soil micro-ecological environment, the study of microflora is cumbersome and time-consuming. All biochemical processes in the soil can only be completed by the action of soil microorganisms. The decomposition and mineralization of organic matter in the soil mainly depends on the action of microorganisms, especially bacteria. Therefore, the number and activity of microorganisms in the soil are limited to a certain extent determines the fertility of the...
