Spring and autumn field experiments were conducted to investigate the impacts of two endophytic strains of Fusarium culmorum（F.c）and Fusarium pseudograminearum（F.p）on yields，rhizospere soil nutrients，microbial populations and bacterial diversity of three cabbage varieties（‘Zhonggan 21’is susceptible to verticillium wilt and black rot，‘Manyue 56’is resistant to wilt，‘Ximei’is resistant to verticillium wilt and black rot）．The results showed that the different fungicides had no significant effect on the spring yields of 3 cabbage varieties，but significantly increased the autumn yield of‘Zhonggan 21’，and had no significant effect on the autumn yield of‘Manyue 56’and‘Ximei’．Particularly，the number of culturable microbial populations in the rhizosphere soil of‘Manyue 56’and‘Ximei’was bigger than that of‘Zhonggan 21’．However，microbial agent applications can significantly increase the number of bacteria，actinomycetes，ammonifying bacteria，and nitrogen fixing bacteria，and improve the community structure of bacteria and fungi in the rhizosphere soil of‘Zhonggan 21’．In general，the two endophytic Fusarium strains could reshape rhizosphere health by regulating the microbial community，diversity，and nutrient indicators in the rhizosphere soil to alleviate the obstacles on continuous cropping in cabbage．In conclusion，Fusarium culmorum and Fusarium pseudograminearum might act as a promising plant probiotics for the preparation of microbial fertilizers．
