摘要
为探究植保无人机对园林植物黄山栾喷雾的最优作业参数,使用四旋翼植保无人机开展园区内喷雾试验,调查喷雾作业后黄山栾上的雾滴沉积分布情况.经比较得出,试验机型对黄山栾喷雾较优的作业参数为喷液量750 mL/株、作业高度3.5 m、作业速度 1m/s.调查发现,黄山栾不同冠层的雾滴覆盖密度和沉积量多数呈现为上层＞中层＞下层.极差分析结果显示,影响飞防作业中雾滴覆盖密度与沉积量的主要因素是作业速度,其次是喷液量和作业高度.研究结果可为植保无人机在高冠乔木上的推广应用提供依据,并为园林病虫害统防统治提供技术参考.
Abstract
This study aimed to determine the optimal operating parameters of the plant protection UAV for spraying the garden plants Koelreuteria bipinnata.A small quadrotor UAV was used to carry out the spraying tests and the deposition of droplets in the canopy of K.bipinnata was investigated.The results showed that the best operating parameters were a spray liquid volume of 750 mUplant,an operation height of 3.5 m,and an operating speed of 1 m/s.The droplet coverage density and deposition amount varied across different layers of the canopy of K.bipinnata,with the upper layer showing the highest coverage and deposition,followed by the middle and lower layers.The results of range analysis showed that the deposition density and droplet amount were primarily influenced by the operating speed,followed by the amount of spray liquid and operating height.The result of this study could provide a theoretical foundation for the popularization and application of plant protection UAVs on tall trees,and provide technical references for large-scale,rapid,and unified control of garden diseases and pests.
