Abstract

The invention belongs to the technical field of bioengineering. The invention discloses a bacillus pumilus 21-14, which is preserved in the China General Microbiological Culture Collection Center on September 6, 2024, the China General Microbiological Culture Collection Center is called CGMCC for short, the registration number of the strain preservation center is CGMCC NO.31892, the strain preservation date is September 6, 2024, and the address of the preservation unit is No.3, Yard 1, Beichen West Road, Chaoyang District, Beijing. The bacillus pumilus strain 21-14 is easy to culture, short in period, free of ecological toxicity, rich in available carbon source variety and high in saline-alkaline resistance, growth and development of potatoes can be promoted by dissolving phosphorus, producing IAA and the like, improvement of biomass of crops in saline-alkali soil is facilitated, and meanwhile growth of streptomyces scabies can be effectively inhibited.
