The invention discloses a preparation method and application of a
paenibacillus polymyxa microbial inoculum for promoting the growth of
festuca arundinacea and improving soil, and belongs to the field of microbial agricultural application and
grassland ecological restoration, the
paenibacillus polymyxa YF is preserved in China General
Microbiological Culture Collection Center on December 21, 2020, the preservation number of the
paenibacillus polymyxa is CGMCC No.21517. By utilizing the
colonization capability and
metabolic activity of the
paenibacillus polymyxa in soil, on one hand, the
plant height, the
leaf width, the
fresh weight and the
dry weight of
festuca arundinacea are remarkably increased; on the other hand, the
soil pH value can be adjusted, the
organic matter content is increased, the soil physical and chemical environment is optimized, meanwhile, the
stress resistance of
festuca arundinacea is enhanced, and complex climate and soil conditions in Qinghai regions are adapted. The
paenibacillus polymyxa microbial inoculum is applied to
festuca arundinacea planting, has both
economic benefits and ecological benefits, and has wide practical application value.
