摘　　要：为了研究植保无人飞机在苹果果树雾滴分布的情况,选用韦加JF01-20电动八旋翼四轴植保无人机作为测试平台,探讨飞行速度和喷雾助剂对于苹果果树雾滴分布的影响。试验设定了6组试验处理,以水敏纸为雾滴分布测试工具,分别布置在果树的上中下冠层,统计果树立体冠层的雾滴分布数据。研究结果表明:果树相同冠层水平面的雾滴分布差异性较大,雾滴分布的变异系数值范围在49.1%~227.6%之间变化;雾滴的分布数值结果在果树冠层从上至下逐步降低,雾滴分布的数值结果随着飞行速度的增加而降低,各雾滴测试指标的变化趋势相同;添加助剂后,各个试验处理以及冠层间的雾滴分布结果具有显著的提升。研究结果可为植保无人飞机应用于苹果果树的喷洒提供数据支持。In order to study the distribution of droplets of plant protection drones in apple fruit trees,the JF01-20 electric octa-rotor four-axis plant protection drone was selected as the test platform to explore the effects of flight speed and spray adjuvant on the distribution of droplets in apple fruit trees.The experiment set up six groups of experimental treatments,using water-sensitive paper(WSP)as a test tool for distributing droplets.The WSPs were respectively arranged on the upper,middle,and lower canopy layers of apple trees.The distribution data of droplets in the canopy layer of apple trees were counted.The research results show that the distribution of droplets on the same canopy level of fruit trees is quite different,and the variation coefficient of droplet distribution varies from 49.1%to 227.6%;the numerical results of the distribution of droplets gradually decrease from top to bottom in the canopy of fruit trees.The numerical results of droplet distribution decrease with the increase in flight speed,and the changing trend of each droplet test index is the same.After adding the adjuvant,the results of the droplet distribution between each experimental treatment and canopy were significantly improved.The research provides data support for the spraying application of plant protection drones on apple orchards.
