Abstract: Objective To study the deposition distribution law and pest control efficiency of droplet spraying operation of plant protection UAV. Method Using UAV and boom sprayer to carry out spraying test, with Kromekote card and filter paper as sampler to collect droplets, study the deposition law of droplets in cotton canopy, compare the pest control efficiency of two kinds of plant protection machinery. Results The results of test show that in the range of effective spray amplitude, the droplets of UAV spraying operation are mainly concentrated in the upper part of cotton canopy, the deposition and coverage of droplets in the middle and lower of cotton canopy are lower, The droplet drift of UAV spraying on the upper and lower wind direction is significantly different, and the average drift percentage of the upper wind direction is 4.93%, the average drift percentage of lower wind direction is 14.96%, and the fluctuation is large, JT-30 plant protection UAV and 3W-1000Y boom sprayer had better control effect on cotton aphid after 7 days of spraying, and the control effect on cotton leafhopper was better after 15 days of spraying. Conclusion From the operation effect of UAV, the penetration of droplets in cotton canopy is poor, the phenomenon of droplet drift of lower wind direction is more prominent, the control effect of aphids is good, and the research results can provide theoretical basis and technical support for the field operation of plant protection UAV.

摘要: 目的 研究植保无人机喷施作业雾滴的沉积分布规律和病虫害防治效果,为植保无人机田间作业提供理论依据和技术支持。方法 使用无人机和喷杆喷雾机进行喷施试验,以卡罗米特纸卡和滤纸作为取样器采集雾滴,研究雾滴在棉花冠层的沉积规律,比较两种植保机械的病虫害防治效果。结果 在有效喷幅范围内,无人机喷施作业雾滴主要集中在棉花冠层上部,棉花冠层中部和下部雾滴沉积量和覆盖率均较低;无人机施药雾滴在上风向和下风向的飘移量有显著差异,上风向雾滴平均飘移百分比为4.93%,下风向平均飘移百分比为14.96%,且波动较大;JT-30植保无人机和3W-1000Y悬挂式喷杆喷雾机在施药7 d后对棉蚜防治效果较好,在施药后15 d对棉叶螨防治效果较好。结论 雾滴在棉花冠层的穿透性较差,下风向雾滴飘移现象较突出,对蚜虫的防治效果较好。
