[Effects of salt stress on bacterial community composition and diversity in rhizosphere soil of ].

Salinization environment affects the normal growth and development of plants, as well as the microbial community in the rhizosphere. To explore the succession dynamics of bacterial communities in the rhizosphere soil of under salt stress condition, we performed 16S rRNA high-throughput sequencing to determine the bacterial community composition and diversity of in the rhizosphere under different salt stress concentrations, measured the effects of salt stress on the growth and development of and soil physicochemical pro-perties, and analyzed the correlation between community composition of rhizosphere bacteria and the soil environmental factors. The results showed that compared with the control, salt stress reduced growth rate and health degree of , and significantly decreased the content of soil organic matter, nitrogen and phosphorus.
