Problems solved by technology

Therefore, the rhizosphere growth-promoting bacteria isolated from fluvo-aquic soil, forming a symbiotic system with crops, and using bioremediation to improve fluvo-aquic soil have become a current research hotspot, but so far there have been no public reports on rhizosphere growth-promoting bacteria specially used for peanuts.

Abstract

The invention relates to peanut growth promoting rhizobacteria HS2 and an application thereof. The peanut growth promoting rhizobacteria is peanut growth promoting rhizobacteria HS2 which is classified and named bacillus subtilis and collected in the China General Microbiological Culture Collection Center on October 31, 2014, with a collection number CGMCC No.9888; the insoluble potassium-containing silicate can be effectively converted into soluble potassium salt, organophosphorus is dissolved, and the utilization rate of fertilizer is improved; and the peanut growth promoting rhizobacteria HS2 is effectively applied to peanut planting to promote the peanut growth and increase the yield, and the application is a great innovation in microorganism and peanut planting.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a peanut rhizosphere growth-promoting bacterium HS2 and its application. Background technique [0002] Sandy fluvo-aquic soil has strong permeability and good ventilation, and aerobic microbial activities are dominant, which can promote the decomposition of organic matter and accelerate the mineralization of organic matter. And the soil is loose and easy to cultivate. The capillary action of the soil is strong, the water runs fast, and there is a phenomenon of "night tide". The suitable tillage period is also long, and the seedlings are easy to stand; but the nutrient content is low, the fertilizer retention performance is poor, and the crops are prone to defertilization and premature aging in the later stage. At present, most of the soil has been used as arable land, and its utilization rate reaches 92.3%. Targeted improvement measures in the future: plant according to the soil,...
