摘　　要：以草莓品种‘章姬’为试验材料,设置不同化肥减施量,并根施生防菌剂,研究不同化肥减施比例配施复合生防菌剂对草莓产量、品质以及病害防治的影响。结果表明:在不同化肥减施量处理下,施用生防菌剂均可促进草莓品质和产量的提高,减少炭疽病、白粉病和灰霉病等病害的发生。在减肥5%和10%的基础上(处理A、处理B),施用生防菌剂对草莓增产及病害防治效果较佳。与对照相比,处理A和B的草莓平均单果重分别增加14.6%和12.1%,可溶性固形物含量分别提高6.8%和9.4%,产量分别提高11.7%和10.0%,对草莓炭疽病、白粉病和灰霉病的平均防效分别为59.5%、51.3%、58.4%和52.4%、50.7%、55.9%。Taking the strawberry variety‘Akihime’as test material,different fertilizer reduction rates were set up and biocontrol agents were apply to the root to study the effects of different fertilizer reduction rates combined with composite biocontrol agents on strawberry yield,quality,and disease control.The results showed that under different fertilizer reduction treatments,the application of biocontrol agents could promote the improvement of strawberry quality and yield,and reduce the occurrence of diseases such as anthracnose,powdery mildew,and gray mold.Among them,on the basis of reducing fertilizer application by 5%(treatment A)and 10%(treatment B),the application of biocontrol agents had better effects on increasing yield and disease control of strawberries.Compared with the control,the strawberry average single fruit weight of treatment A and B increased by 14.6%and 12.1%,the soluble solid content increased by 6.8%and 9.4%,and the yield increased by 11.7%and 10.0%,respectively;The average control effects on strawberry anthracnose,powdery mildew,and gray mold were 59.5%,51.3%,58.4%and 52.4%,50.7%,55.9%,respectively.
