Abstract

The invention relates to relates to a peanut root growth-promoting bacterium HS9 and application thereof. The peanut root growth-promoting bacterium HS9 is classified and named as bacillus flexus, and collected in China General Microbiological Culture Collection Center on October 31, 2014, with the collection number of CGMCC No. 9889; the peanut root growth-promoting bacterium HS9 is capable of effectively converting slightly soluble potassium-containing silicates into soluble potassium salts, decomposing organic phosphorus and increasing the utilization rate of fertilizers; the peanut root growth-promoting bacterium HS9 is effectively applied to peanut planting, and is capable of promoting the growth of the peanut and increasing the peanut yield, and 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 HS9 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 a...
