Abstract

The invention relates to peanut rhizosphere growth-promoting bacteria HS11 and application thereof. The peanut rhizosphere growth-promoting bacteria are peanut rhizosphere growth-promoting bacteria HS11 and classified and named as bacillus megatherium and are stored in the China General Microbiological Culture Collection Center with a number of CGMCC No.9891 on Oct.31, 2014. With the adoption of the peanut rhizosphere growth-promoting bacteria HS11, hard-to-dissolve potassium-containing silicate can be effectively converted into dissoluble potassium salt, organophosphate can be degraded, the utilization rate of fertilizer can be increased, the peanut can be effectively planted, the growth of the peanut can be promoted, and the output can be increased; the peanut rhizosphere growth-promoting bacteria HS11 are a major innovation in microbial and peanut planting.

Description

technical field [0001] The invention relates to microorganisms, in particular to a peanut rhizosphere growth-promoting bacterium HS11 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 ...
