    摘要:

    为探究植保无人机喷施簕菜（Acanthopanax trifoliatus）叶面肥的可行性以及最佳作业参数组合，使用极飞P20-2019款四旋翼植保无人机开展簕菜叶面肥喷雾试验，设计3因素3水平正交试验，考察喷施含量、飞行速度、作业高度对喷雾质量、簕菜产量及叶片品质的影响。结果显示，飞行速度和作业高度对喷雾质量影响显著，雾滴沉积密度与沉积量呈现极强正相关；此外，喷施含量、飞行速度、作业高度对簕菜产量、簕菜叶片品质的影响显著。喷施含量为推荐含量的5倍、飞行速度为1.0 m/s、作业高度为2.0 m时，雾滴沉积密度为188.212 个/cm2，雾滴沉积量为0.269 μg/cm2。此时，植保无人机喷施簕菜叶面肥施肥效果最好，相较空白对照组簕菜产量提高27.46%、簕菜叶绿素含量提高33.23%。研究表明，使用植保无人机喷施高含量簕菜叶面肥可行。

    Abstract:

    The XAG P20-2019 quadcopter UVA was used to spray foliar fertilizer on Acanthopanax trifoliatus to study the feasibility and optimal combination of working parameters for spraying foliar fertilizer on Acanthopanax trifoliatus with unmanned aerial vehicle （UAV）. The orthogonal experiment with three factors and three levels was designed to investigate the effects of the concentration of spraying， the speed of flight and the height of working on the quality of spraying， the yield of Acanthopanax trifoliatus and the quality of leaf. The results showed that the speed of flight and the height of working had significant effects on the quality of spraying， and the density of droplet deposition had a strong positive correlation with the amount of droplet deposition. The effects of the concentration of spraying， the speed of flight and the height of working on the yield and quality of leaf in Acanthopanax trifoliatus were significant. The density and the amount of droplet deposition was 188.212/cm2 and 0.269 μg/cm2 when the concentration of spraying， the speed of flight and the height of working was 5 times the concentration recommended，1.0 m/s and 2.0 m. At this time， the effect of spraying foliar fertilizer on Acanthopanax trifoliatus with UAV was the best， with a 27.46% increase in the yield of Acanthopanax trifoliatus and a 33.23% increase in the content of chlorophyll in Acanthopanax trifoliatus compared with that of the control. It is indicated that it is feasible to use UAV to spray foliar fertilizer with high concentration on Acanthopanax trifoliatus. It will provide references for using the same type of UVA to spray foliar fertilizer.
