摘　　要：为研究植保无人机在不同飞行速度和飞行高度下对丘陵荔枝冠层雾滴沉积分布的影响,优选作业参数并评估其对荔枝麻点病的防治效果,在丘陵荔枝园使用T50型植保无人机进行了一系列试验。结果表明,当飞行速度为2 m/s且飞行高度为4 m时,上、下冠层的雾滴沉积分布效果最佳。以此作业参数进行3次麻点病防治施药后,人工100%剂量区和植保无人机100%剂量区的防治效果分别为74%和71%,而植保无人机80%剂量区也达到了66%的防效。而使用植保无人机能显著提高荔枝园病虫害防治效率,植保无人机施药用水量仅为人工的14.4%,平均每棵树的施药时间也仅为人工的12%。本研究可为丘陵荔枝园中植保无人机的操作参数选择和实际应用提供参考。To investigate the impact of Plant Protection UAV on droplet deposition distribution within the canopy of lychee trees in hilly areas under different flight speeds and relative flight heights,and to optimize operational parameters while evaluating their effectiveness in controlling lychee anthracnose,this study conducted trials using a T50 UAV in a hilly lychee orchard.The results showed that when the flight speed was set at 2 m/s and the flight height at 4 m,the droplet deposition effect on the canopy was optimal.After three applications for the control of lychee anthracnose using these parameters,the control efficacy in the 100%dosage area by manual spraying and UAV spraying was 74%and 71%,respectively,while the 80%dosage area sprayed by UAV achieved a control efficacy of 66%.Furthermore,the use of the UAV significantly improved the efficiency of pest and disease control in lychee orchards.The water consumption for pesticide application using the UAV was only 14.4%of that required by manual methods,and the average time per tree was reduced to just 12%of manual application time.This study provided valuable reference for the selection of operational parameters and practical application of plant protection UAV in hilly lychee orchards.
