Rhizosphere bacteria play an important and important role in plant health and growth by helping plants withstand adverse effects such as soil salinity. Plastic film mulch is an important way to control soil properties and improve yields, especially in saline soils. However, whether and to what extent there is a relationship between these improvements and rhizosphere bacteria remains unclear. Here, field studies and greenhouse mesocosm experiments show that mulching plastic sheets with saline-alkaline soils enhances soybean growth outdoors. It was shown to grow better in unsterilized saline-alkali soil than in sterilized saline-alkali soil. By detecting changes in soil properties and analyzing high-throughput sequencing data, we found that the effect of film mulching effectively maintained soil water content, clearly reduced soil salinity, and reduced bacterial and fungal communities in the rhizosphere was found to reduce I have found it makes a big difference. Then the correlation analysis method was applied. Optimizing soil properties improved the survival conditions for soil microbes and promoted increased relative abundance of potentially beneficial microbes contributing to soybean growth. In addition, a taxonomy of potentially important rhizosphere microbial OTUs was identified. In conclusion, our study suggests an important influence of soil properties as a driver of changes in rhizosphere microbial communities, suggesting that rhizosphere bacteria in promoting plant performance in saline-alkaline soils under plastic sheet mulching shows the important role of it shows.
