摘　　要：以大叶女贞为研究对象,选用植保无人机大疆T30喷施5%萘乙酸1.5 L/hm^(2),分析植保无人机不同喷施量(96.5、171.5 L/hm^(2))和飞行速度(1.9、1.0 m/s)下大叶女贞雾滴沉积密度、沉积量及均匀性、穿透性和疏果率,为植保无人机施药技术在园林植物上的应用提供参考。结果表明,植保无人机在大叶女贞盛花期喷施5%萘乙酸1.5 L/hm^(2),当喷施量171.5 L/hm^(2)、飞行速度1.0 m/s(处理2)时,雾滴沉积量高于处理1(喷施量96.5 L/hm^(2)、飞行速度1.9 m/s),分布均匀性和穿透性好于处理1。其中,特征树2总体上表现最佳,其上、中、下层的雾滴沉积密度分别为32.40、51.75、39.13个/cm^(2),均匀性分别为39.1%、44.3%、51.4%,雾滴沉积量分别为0.52、0.54、0.30μL/cm^(2),穿透性为64.9%,施药后30 d对大叶女贞的最大疏果率达58.5%。Taking Ligustrum lucidum as the research object,plant protection unmanned aerial vehicle(UAV)Dajiang T30 was selected to spray 5%naphthylacetic acid(NAA)of 1.5 L/ha.The deposition density,deposition amount,uniformity,penetration of spraying droplet on Ligustrum lucidum by plant protection UAV and fruit thinning rate were analyzed under different spraying amounts(96.5,171.5 L/ha)and flight speeds(1.9,1.0 m/s),so as to provide reference for the application of UAV pesticide application technology in garden plants.The results showed that when the plant protection UAV sprayed 5%NAA of 1.5 L/ha with spray amount of 171.5 L/ha and flight speed of 1.0 m/s(treatment 2)at full flowering stage of Ligustrum lucidum,the deposition amount of droplets was higher than that of treatment 1(spray amount of 96.5 L/ha and flight speed of 1.9 m/s),and uniformity and penetration were better than those of treatment 1.Among them,feature tree 2 showed the best performance in general.The deposition densities of droplets in the upper,middle and lower layers were 32.40,51.75 and 39.13 droplets/cm^(2),the homogeneities were 39.1%,44.3%and 51.4%,the deposition amounts were 0.52,0.54 and 0.30μL/cm^(2),respectively,and the penetration was 64.9%.The maximum fruit thinning rate was 58.5%at 30 d after application.
