无人机雾化喷头对雾滴在竹林中沉降分布及害虫防效的影响

为明确不同喷头型号对无人机喷雾雾滴在竹林中沉积分布和防效的影响,揭示无人机喷雾的关键技术，研究选用不同型号雾化喷头，开展无人机喷雾雾滴检测和林间防治试验，分析不同喷头型号对雾滴的覆盖密度、沉降率、有效喷幅、密度变异系数和防治效果的影响。结果表明：无人机喷洒系统的雾化喷头对雾滴沉积分布的影响较大，在竹林喷雾中，无人机雾化喷头以SX110015VS型号为宜，其雾滴在竹林中的沉积分布状况最佳，雾滴穿透性最强，防治效果最理想。

Effects of UAV Spray Nozzles on Droplet Deposition Distribution and Pest Control Effect in Bamboo Forest

In order to know the influence of different spray nozzles on the deposition distribution and pest control effect of UAV spraying droplets in bamboo forests, and to reveal the key technology of UAV spraying, spray nozzles of different types are selected and the testing of spraying droplets and the experiment on its pest control effect are carried out to study the effects of spray nozzles of different types on droplet coverage density, deposition rate, effective spray amplitude, coefficient of variation of droplet density and control effect. The results show that the UAV spray nozzle has larger influences on spraying droplet deposition distribution, and SX110015VS is the best atomizer for UAV in bamboo forest spray, with the droplets having the best deposition distribution in the bamboo forest, the strongest penetration and the best pest control effect.
