摘　　要：植保无人机作为一种新型的施药机械,在西藏地区应用极少。为探索其对西藏飞蝗的防治效果,本文选用了绿僵菌作为施药药剂,对比了极飞P20与人工背负式智能电动喷雾器对西藏飞蝗的防治效果。结果表明:使用极飞P20进行施药,对西藏飞蝗具有良好的控制作用,且安全无药害。与人工施药相比,使用极飞P20施药,可节约用水96.67%,每667 m^(2)减药20%,大大提高了农药利用率。Plant Protection UAV,as an new sraying machine,is rarely applied in Tibet.To explore its control effect on locusts in Tibet,this paper chose Metarhizium anisopliae as pesticide,and compared the control effect of polar flying P20 with artificial backpack intelligent electric sprayer on locusts migratory in Tibet.The results showed:the application of polar fly P20 had good control effect on Tibet locust migratoria,and it was safe and harmless.Compared with manual application,the application of Jifei P20 could save 96.67% water and reduce 20% pesticide per mu,and greatly improve the utilization rate of pesticide.
