Abstract：A total of 183 endophytic bacteria strains and 55 rhizosphere bacteria strains were isolated by tissue separation and dilution separation methods from strawberry root，stem，leaf and rhizosphere soil．Among them，9 strains showing broad-spectrum antagonistic effects against 4 strawberry fungal pathogens，including Pilidium concavum，Botrytis cinerea，Fusarium oxysporum and Alternaria alternate．Combining the results of morphological trait，physiology and biochemistry character，and molecular identification，strains G3-23，J3-20 and G3-29 were identified as Bacillus velezensis；J6-1，J1-4，G2-12，G3-K2，and J1-11 were identified as B. subtilis；G3-20 was identified as B. halotolerans；and G3-17 was identified as B. cereus．Strain G3-23 could secrete protease and cellulase，and had a good control effect on strawberry tan-brown leaf spot caused by P. concavum．Besides，this strain could successfully colonize on strawberry leaf，showing a good biocontrol potential．
