Abstract

The invention relates to peanut plant growth promoting bacteria HS4 and application thereof. The peanut plant growth promoting bacteria HS4 is classified and named bacillus muralis, is preserved in the China General Microbiological Culture Collection Center on October 31, 2014, and has a preservation number of CGMCC No.9887. The peanut plant growth promoting bacteria HS4 can be used for effectively solving the problems of converting insoluble potassium-containing silicate into soluble sylvite, decomposing organic phosphorus, improving fertilizer utilization for effective peanut planting, promoting peanut growth and improving yield, and is a great innovation on microorganisms and peanut planting.

Description

technical field [0001] The invention relates to microorganisms, in particular to a peanut rhizosphere growth-promoting bacterium HS4 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...
