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 a peanut growth-promoting rhizobacterium and the application thereof. The peanut growth-promoting rhizobacterium is the peanut growth-promoting rhizobacterium HS10 which is classified and named as bacillus tequilensis and collected in China General Microbiological Culture Collection Center on October 31, 2014, with the collection number CGMCC No. 9890; the peanut growth-promoting rhizobacterium is capable of effectively transforming insoluble potassium-containing silicates into soluble potassium salts, decomposing organic phosphorus and increasing the fertilizer utilization rate and can be effectively applied to peanut planting to promote the growth of the peanut and increase the peanut yield; in short, the peanut growth-promoting rhizobacterium is a great innovation in microorganisms and peanut planting.

Description

technical field [0001] The invention relates to microorganisms, in particular to a peanut rhizosphere growth-promoting bacterium HS10 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, rationally ...
