摘　　要：灰霉病是保护地栽培韭菜的重要病害。选取5种木霉制剂进行韭菜灰霉病的田间防治试验,在苗期进行喷雾处理,结果表明,深绿木霉20111、哈茨木霉C61、哈茨木霉LTR-2、哈茨木霉21990和深绿木霉23617对韭菜灰霉病的防治效果分别为13.62%、68.93%、64.00%、91.72%和87.23%,其中,哈茨木霉21990防效最优。在此基础上进行木霉与枯草芽孢杆菌协同防治试验,结果显示,在韭菜扣棚前随水冲施哈茨木霉21990,待韭菜长到5 cm左右时喷施枯草芽孢杆菌,田间防效可达74.07%。Grey mold is an important disease for leek cultivation in protected fields.Five Trichoderma strains were selected and sprayed on leek seedling and field control experiment was carried out on leek gray mold.The results showed that the control effects of Trichoderma atroviride 20111,T.harzianum C61,T.harzianum LTR-2,T.harzianum 21990 and T.atroviride 23617 were 13.62%,68.93%,64.00%,91.72%and 87.23%,respectively.Among them,T.harzianum 21990 had the best control effect.On this basis,a cooperative control test on Trichoderma sp.and Bacillus subtilis was carried out.The results indicated that spraying T.harzianum 21990 mixed with water before covering the leek planted shelter,then spraying Bacillus subtilis when the leek grew up to about 5 cm in height,the field control effect could reach 74.07%.
