The invention discloses a strain which is derived from a mangrove forest ecological system and has growth-promoting and salt-resisting functions and application of the strain. The strain is preserved in the Guangdong Microbial Culture Collection Center on July 13, 2022, the taxonomic name is Pantoeatewartii, and the preservation number is GDMCC No: 62620; the strain can fix nitrogen, dissolve potassium and phosphorus, promote plant growth and improve and relieve plant salt stress; compared with reported strains, the strain can generate volatile organic compounds with a growth promoting function under salt treatment, and can be used for preparing plant growth promoters, microbial fertilizers, soil amendments and the like; good application prospects are realized. 本发明公开了一株来源于红树林生态系统具有促生耐盐功能的菌株及其应用。所述菌株于2022年7月13日保藏在广东省微生物菌种保藏中心，分类学名称为Pantoeastewartii，保藏编号为：GDMCC No：62620；该菌株能够固氮、解钾、溶磷、促进植物生长、提高缓解植物盐胁迫；与已报道菌株相比，其在盐处理下，可以产生具有促生功能的挥发性有机物，可以用于制备植物促生剂、微生物肥料、土壤改良剂等等；具有很好的应用前景。
