Effects of Effective Microorganisms on the Yield, Quality and the Incidence Rate of Verticillium wilt of Continuous Cropping Eggplant in Facility

Taking facility-cultivated eggplant as test materials,the effects of four commonly used microbial inoculants on the yield,quality,incidence rate and disease index of Verticillium wilt in facilities with high incidence of Verticillium wilt were studied with artificial watering method,in order to provide reference for the biological control of Verticillium wilt in continuous cultivation of eggplant.The results showed that the four microbial preparations could significantly increase eggplant yield,quality,rhizosphere soil enzyme activity,improve rhizosphere microflora,and reduce the incidence and disease index of Verticillium wilt.EM inoculants had the best effect,followed by Bacillus subtilis,Trichoderma,and Arbuscular mycorrhizal fungi.This study confirmed that in areas with high incidence of eggplant Verticillium wilt,effective microbial preparations can be used to treat seedling substrate and field soil,which can significantly reduce the incidence and disease index of eggplant Verticillium wilt,and improve eggplant yield and quality.
