Abstract

The invention relates to peanut plant growth promoting bacteria HS3 and an application thereof. The peanut plant growth promoting bacteria is peanut plant growth promoting bacteria HS3 and is classified and named as bacillus acidiceler which is collected in General Microorganism Center of China Committee for Culture Collection of Microorganisms with the collection number CGMCC NO.9886 on 31st October, 2014. The peanut plant growth promoting bacteria HS3 and the application have the advantages that the problem that difficultly-soluble potassium-containing silicate is converted into soluble potassium salt can be effectively solved, organophosphorus can be degraded, the utilization rate of fertilizers can be increased, the peanut plant growth promoting bacteria HS3 can be effectively used for planting peanuts, the growth of peanuts can be promoted, the yield can be increased, and the peanut plant growth promoting bacteria HS3 is an important innovation on microorganisms and peanut planting.

Description

technical field [0001] The invention relates to microorganisms, in particular to a peanut rhizosphere growth-promoting bacterium HS3 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...
