| 农药雾滴信息是评价农药施用质量的主要指标, 农药雾滴采集器的设置对于获取雾滴信息有较大的影响。针对如何科学地设置农药雾滴采集器从而准确地获取真实雾滴信息等问题, 本文以油动单旋翼植保无人飞机和电动六旋翼植保无人飞机为供试药械, 以诱惑红为雾滴示踪剂, 采用将卡罗米特纸卡直接固定在棉花叶片上和使用金属杆固定2种方法采集雾滴信息, 研究2种方法下采集的雾滴信息的差异。结果表明, 油动单旋翼植保无人飞机作业, 在添加助剂情况下, 金属杆固定法在棉花冠层上、中、下层采集的雾滴体积中径分别为(435.4±66.1)、(434.6±68.3)μm和(398.9±66.7)μm显著大于植株固定法在相应部位采集的雾滴体积中径(361.2±93.1)、(351.9±95.7)μm和(338.1±71.1)μm；金属杆固定法采集的雾滴密度在棉花冠层上层为(29.9±13.6)个/cm2, 中层为(13.4±4.5)个/cm2, 下层为(6.7±4.2)个/cm2, 显著大于植株固定法在相应冠层采集的雾滴密度(12.9±5.0)、(8.6±3.4)个/cm2和(1.9±1.3)个/cm2。添加助剂能够提升两种植保无人飞机喷施作业的雾滴覆盖率和雾滴的沉积量, 提高农药的利用率。 |

| Droplet information is the main index for evaluating the quality of pesticide application, and the setting of pesticide droplet collector has a great influence on the droplet information. Plant-protection UAV is characterized by high efficiency, safe operation and strong applicability, which has developed rapidly in recent years and has become one of the main prevention and control methods for pests and diseases. However, there still are some problems during the droplet information collection, such as how to scientifically set up the droplet collector to accurately obtain the real droplet information. In this study, single rotor fuel-powered unmanned aerial vehicle and six rotor electric unmanned aerial vehicle were used as the test equipment, allure red was used as the droplet tracer, and two methods (Kromekote card directly fixed on cotton leaves or fixed by metal rod) were used to collect the droplet information. The difference in the droplet information collected by using the two methods was studied. The results showed that with the addition of adjuvants, the volume median diameter of droplets collected by metal rod fixation method on the upper, middle and lower layers of cotton canopy were (435.4 ± 66.1)μm, (434.6 ± 68.3)μm and (398.9 ± 66.7)μm, respectively, in the operation of single rotor fuel-powered unmanned aerial vehicle, which were significantly higher than those collected by plant fixation method ［(361.2±93.1)μm, (351.9±95.7)μm and (338.1±71.1)μm］. With the addition of adjuvants, the droplet densities collected by the metal rod fixation method on the upper, middle and lower layers of cotton canopy were (29.9±13.6), (13.4±4.5)pcs/cm2 and (6.7±4.2)pcs/cm2, respectively, which were significantly higher than those by the plant fixation method ［(12.9±5.0), (8.6±3.4)pcs/cm2 and (1.9±1.3)pcs/cm2］. The addition of adjuvants can improve the droplet coverage and droplet deposition during the operation of two UAVs and improve the utilization rate of pesticides. |
