To further optimize the use of weed control equipment in wheat fields,plant protection equipment including multi-rotor drone,self-propelled rod-type sprayer,stretcher-type sprayer and backpack-type electric sprayer were selected to spray diflufenican·flufenacet·flurtamone 33%SC as pre-emergence herbicide,and their working efficiencies and weed control effects were compared in 2022.The results showed that the control effects of the four types of equipment on broadleaf weeds were 96.94%~98.98%and 91.98%~95.92%respectively,and those of multi-rotor drone,self-propelled rod-type sprayer and stretcher-type sprayer on grass weeds were 84.36%~94.40%and 74.00%~84.53%respectively which were significantly higher than in stretcher-type sprayer,at 30 and 100 days after herbicide application.Overall,the self-propelled rod-type sprayer should be used as the main plant protection equipment for herbicide application in large-scale wheat production with the advantages of better control effect,higher crop safety and working efficiency.
