Abstract

The present invention relates to peanut rhizosphere growth-promoting bacterium HS9 and its application. The peanut rhizosphere growth-promoting bacterium is peanut rhizosphere growth-promoting bacterium HS9. The General Microorganism Center of the Culture Preservation Management Committee, the preservation number is CGMCC No.9889, which can effectively solve the problem of converting insoluble potassium-containing silicates into soluble potassium salts, decomposing organic phosphorus, improving the utilization rate of fertilizers, and effectively used in the cultivation of peanuts , to promote the growth and increase the yield of peanuts, is a major innovation in microorganisms and peanut cultivation.

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...
