摘　　要：[目的]明确无人机不同喷液量对大豆一年生禾本科杂草的防治效果。[方法]以背负式静电喷雾器常量喷雾为对照,研究植保无人机喷施不同喷液量5%精喹禾灵EC对大豆一年生禾本科杂草的防治效果。[结果]5%精喹禾灵EC制剂用药量为1 050 m L/hm2,植保无人机喷液量为7 500~12 000 m L/hm^2时对大豆安全,植保无人机喷液量为9 000、10 500 m L/hm^2时对夏大豆田一年生禾本科杂草的防治效果较好,与背负式静电喷药450 kg/hm^2时效果相当。[结论]试验结果为无人机的大面积推广应用提供了理论依据。[ Objective ] The aim was to study control effect of different spray amounts of unmanned aerial vehicle on annual gramineous weeds in soybean field. [ Method ] Taking constant spray of knapsack electrostatic sprayer as control,we studied control effect of different spray amounts of 5% quizalofop-PEC sprayed by unmanned aerial vehicle on annual gramineous weeds in soybean field. [Result] The dosage of 5% quizalofopPEC was 1 050 mL/hm2 ,the unmanned aerial vehicle at spray amount of 7 500 -12 000 mL/hm2 was safe to soybean,and the unmanned aerial vehicle at spray amount of 9 000 and 10 500 mL/hm2 had good control effect on control effect of knapsack electrostatic sprayer at spray amount of 450 kg/hm2 application of unmanned aerial vehicle. annual gramineous weeds in soybean field ,which was equal to the [ Conclusion] The results provide theoretical basis for extensive
