【Objective】This study is to understand the current research status of plant growth promo- ting rhizobacteria (PGPR) both domestically and internationally, and to explore the potential applications and development prospects of PGPR in agricultural production and planting, including its potential in promoting plant growth, improving soil quality, and reducing the use of chemical pesticides. 【Method】 Based on the Web of Science core collection database, CiteSpace and other tools were used to visually an- alyze the number of publications and disciplinary distribution, collaboration relationships between pub- lishing countries and institutions, publishing journals, major research hotspots, and development trends. 【Result】The main publishing countries included China, India, the United States, Brazil, and Australia, and their research in the field of plant science was the most prominent. The main publishing journals in- cluded Frontiers in microbiology, Applied Soil Ecology, and Bioresource Technology. In addition, keyword clustering analysis showed that research mainly focused on 10 areas including aerobic stability, microbial biomass, microbial diversity. 【Conclusion】The application of PGPR in plant cultivation had become a hot research topic, and research mainly focuse on the effects of microbial agents on plant rhizosphere communities and microbial communities. In addition, future research trends may include the effects of microbial agents on plant rhizosphere communities, integration with other agricultural technologies, and deeper mechanistic studies to further promote the development of plant cultivation.
