The invention discloses a salt-tolerant and growth-promoting stenotrophomonas maltophilia as well as a microbial agent and application of the salt-tolerant and growth-promoting stenotrophomonas maltophilia, the salt-tolerant and growth-promoting stenotrophomonas maltophilia is named as stenotrophomonas maltophilia 43B4 and is preserved in the China General Microbiological Culture Collection Center (CGMCC) on April 18, 2022, and the preservation number is CGMCC No. 24710. The active component of the microbial agent comprises the stenotrophomonas maltophilia. The strain is an efficient and stable multifunctional strain screened from saline-alkali soil, has excellent salt tolerance and also has various growth promoting characteristics of reducing salt, decomposing organophosphorus, decomposing potassium, fixing nitrogen and the like, and a microbial agent prepared from the strain can remarkably improve the salt tolerance of plants under salt stress, alleviate the salt damage phenomenon and increase biomass, so t
