摘　　要：植保无人机飞行参数对雾滴分布和作物保护效果有着重要影响。通过选取无人机喷洒高度、飞行速度、喷雾器角度等参数进行正交试验,探讨三种飞行参数对雾滴覆盖均匀性和作物表面覆盖率的影响。响应面结果表明,喷雾器角度和飞行速度对雾滴覆盖均匀性具有显著影响(p<0.05),适当调整喷洒高度和飞行速度可以改善雾滴覆盖均匀性和作物表面覆盖率。植保无人机最优飞行参数为喷洒高度30 m、飞行速度10 m/s、喷雾器角度45°,可显著改善雾滴覆盖均匀性和作物表面覆盖率,从而提高作物的保护和治理效果,研究结果可对植保无人机实际作业提供指导意义。The flight parameters of plant protection UAVs have an important influence on the fog droplet distribution and crop protection effect.Orthogonal tests were conducted by selecting the parameters of UAV spraying height,flight speed and sprayer angle to explore the effects of the three flight parameters on droplet coverage uniformity and crop surface coverage.The response surface results showed that the sprayer angle and flight speed had a significant effect on droplet coverage uniformity(p<0.05),and appropriate adjustment of spraying height and flight speed could improve droplet coverage uniformity and crop surface coverage.The optimal plant protection UAV flight parameters are spray height 30 m,flight speed 10 m/s,and sprayer angle 45°,which can significantly improve the droplet coverage uniformity and crop surface coverage,and thus improve the crop protection and management effects,and the results of the study can provide guidance for the actual operation of plant protection UAVs.
