| 摘 要： | 采用无人机开展竹林喷雾施药防治试验，通过设置5个不同无人机作业航速，分析雾滴在竹林中的沉降率、覆盖密度、密度变异系数、有效喷幅和防治效果，明确无人机的作业航速对喷雾雾滴沉积分布及防效的影响，为构建无人机喷雾施药关键技术体系提供技术支撑。结果表明：无人机作业航速对雾滴沉积分布和防效有较大的影响，当无人机作业航速为2.0 m/s时，竹冠水平与垂直方向雾滴的沉积分布最好，可获得较理想的防治效果。

| Abstract: | The spraying pesticide for pest control in bamboo forest is experimented using unmanned aerial vehicle (UAV). The deposition rate, coverage density, density variation coefficient, effective spraying amplitude and control effect of spray droplets in bamboo forest are analyzed by setting 5 different operating speed of UAV, and the influence of UAV operating speed on droplet deposition distribution and control effect is clarified, which provides technical support for the key technology system for UAV's application to spraying. The results show that the operating speed of UAV has a large influence on the deposition distribution of droplets and the control effect. When the operating speed of UAV is 2.0 m/s, the horizontal and vertical deposition distribution of droplets in bamboo canopy is the best, which ensures the ideal control effect. |
