Abstract：Using the chili variety Chicken Claw x Jilin as the material,the effect of microbial agents on the growth and microbial community of chili pepper in continuous cropping plots was studied through hole application method.The re-sults indicate that the microbial agent(SW)promotes the growth of pepper to a certain extent.The plant height,stem diam-eter,fruit length,fruit width and yield of the plant are significantly higher than those of the control(CK).Notably,the yield is the largest,with an increase of 14.76％compared to the control.The application of microbial agent increases the relative species number and OTU number of fungi and bacteria in the soil.Through KEGG metabolic pathway analysis,it is found that metabolism is the pathway with the most significant enrichment of differential functions,with relative abun-dance of nearly 80％.Comprehensive analysis shows that microbial agent can improve the community structure of soil fungi and bacteria,promote the growth of pepper plant,and increase pepper yield.
