The invention provides a salt-tolerant potassium-solubilizing growth-promoting microbacterium oxydans 41-C8, which is preserved in China General Microbiological Culture Collection Center on January 4, 2021, and has a preservation registration number of CGMCC No.21585. The bacterium can be applied to potassium solubilizing, nitrogen fixation, phosphorus solubilizing and plant growth promotion, and can be used as a salt-tolerant potassium-solubilizing growth-promoting microbacterium oxydans 41-C8. The invention further provides a microbial agent containing the microbacterium oxydans 41-C8 and a preparation method of the microbial agent. The strain has the salt tolerance of 0-7% and the optimal salt tolerance of 3-5%, and has various growth promoting characteristics of nitrogen fixation, organophosphorus and potassium decomposition and the like, and a bacterial solution prepared from the microbacterium oxydans 41-C8 can significantly improve the salt tolerance and growth promoting ability of Chinese cabbages, al
