摘　　要：目的：明确枯草芽孢杆菌生物拌种剂对玉米病虫害的防病和增产效果,为推广应用提供科学依据。方法：将2种杀虫剂分别加入枯草芽孢杆菌生物拌种剂中充分摇匀后,按肥种比1∶50比例均匀混拌玉米种子,阴干后播种。结果：枯草芽孢杆菌生物拌种剂对玉米根腐病防效达80.1%-96.7%,对玉米黑穗病的防效达74.6%-83.3%,对地下害虫防效达66.7%-77.8%,增产率达8.7%-15.7%。结论：该生物拌种剂可以大面积示范推广使用。Objective：The control efficiency and yield-increasing effect of Bacillus subtilis seed dressing agent against maize diseases and pests was studied,which enables to provide scientific basis for popularization and application. Method：Two kinds of insecticide was added to Bacillus subtilis seed dressing agent respectively.Afterbeing mixed completely,maize seeds were mixed with the agent in the proportion of 1∶50 evenly.The dressing seeds were then dried and sowed.Result：The control efficiency of Bacillus subtilis seed dressing agents on the maize root rot disease reached up to 80.1%-96.7%,maize smut 74.6%-83.3%,and underground pests 66.7%～77.8%.The increasing rate of yield was up to 8.7%-15.7%.Conclusion：This agent is suitable for large-scale demonstration and further popularization.
