Drought stress has a significant negative impact on plant growth and development, which seriously affects agricultural production and ecosystem stability. In recent years, plant-microorganism interaction has become an important research direction to improve plant stress resistance. The purpose of this study was to investigate the effects of microorganisms on the growth, photosynthesis and nutrient absorption of Salvia miltiorrhiza under drought stress. The results showed that under drought stress, microbial inoculation significantly increased the biomass of S.miltiorrhiza, which was about 3.61 times that of uninoculated treatment. The chlorophyll content increased by about 85.45%, and the contents of N and K increased by about 27.77% and 33.27%, respectively. In addition, the inoculation of microorganisms also optimized the root morphology of S.miltiorrhiza. Drought stress changed the microbial community composition. The relative abundance of Enterobacteriaceae increased by 5.50%, and the relative abundance of Brucellaceae decreased by about 2.76%. The above results indicate that microorganisms enhance the drought resistance of plants through multiple mechanisms and have the potential to be used as a biological control method for drought resistance. This study provides a new theoretical basis and practical basis for the future research and application of plant resistance under drought stress.
