Abstract Taking ‘Lameizi’ and ‘Xinyangjiao’ as test material，using pot culture experiment method and high-throughput sequencing technology，this paper studied the effects of applying rhizosphere growthpromoting bacteria on pepper growth and rhizosphere microbial community．The results showed that the effects of P1 Bacillus velezensis（Bacillus velezensis）strain on plant height，dry mass，leaf chlorophyll content，plant total nitrogen and total phosphorus contents of these 2 pepper varieties，Xinyangjiao and Lameizi，were significantly higher than that of by the other 4 strain treatments，and also had changed the structure and composition of rhizosphere soil bacteria and fungi community．After P1 strain treatment，the pepper rhizosphere was significantly enriched in and OTU of Bacillus，Lysobacterium，Flavobacterium．
