从湖南省武陵山区4个茶叶种植基地采集茶轮斑病病叶,采用组织分离法对病原菌进行分离,通过致病性、形态学、分子生物学鉴定,确定病原菌为茶拟盘多毛孢(Pseudopestalotiopsis theae)。以病原菌为指示菌,采...展开更多 从湖南省武陵山区4个茶叶种植基地采集茶轮斑病病叶,采用组织分离法对病原菌进行分离,通过致病性、形态学、分子生物学鉴定,确定病原菌为茶拟盘多毛孢(Pseudopestalotiopsis theae)。以病原菌为指示菌,采用平板对峙法从病叶中筛选得到效果最佳的拮抗菌kc-6,抑菌率为79.86%,经鉴定为解淀粉芽孢杆菌(Bacillus amyloliquefaciens)。分析拮抗菌对病原菌菌丝生长的抑制效果,对茶树离体叶...
