Plant protection UAVs have developed rapidly as a new type of orchard pesticide application equipment. This study was conducted to explore the influence of plant protection UAVs' operation parameters on the properties of droplet deposition. The DJI T30 plant protection UAV was used to affect the influences of spray volume (60 L/ha and 90 L/ha), spray height (2m and 2.5m), with or without an adjuvant and spray patterns (Regular pattern and Orchard pattern) on characteristics of droplet deposition. The test results showed that the interaction of multiple factors has no significant difference in most droplet deposition on various layers of fruit trees. The deposition characteristics of droplets were improved at a spray height of 2 m and a spray volume of 90 L/ha in the presence of adjuvants. In the orchard spray pattern, the penetration of droplet deposition is improved, but the impact on droplet density and coverage is different. Overall, the orchard spraying pattern can achieve better coverage, while the droplet density is the opposite. The spray performance is closely related to the spray volume, with or without an adjuvant, spray pattern, and spray height. The research results provide a theoretical basis for selecting appropriate operating parameters and spray patterns for plant protection UAVs in apple orchards.

植保无人机不同喷雾参数对苹果树雾滴沉积特性的影响
植保无人机作为一种新型果园施药设备迅速发展。本研究旨在探讨植保无人机运行参数对雾滴沉积特性的影响。采用大疆T30植保无人机,考察喷雾量(60 L/ha和90 L/ha)、喷雾高度(2m和2.5m)、有无助剂和喷雾模式(常规模式和果园模式)的影响。 )关于液滴沉积的特性。试验结果表明,多因素交互作用下,果树各层大部分液滴沉积情况无显着差异。在助剂存在下,喷雾高度为2 m、喷雾量为90 L/ha时,雾滴沉积特性得到改善。果园喷雾模式下,雾滴沉积的穿透力有所提高,但对雾滴密度和覆盖范围的影响不同。总体而言,果园喷洒模式能够实现较好的覆盖效果,而雾滴密度则相反。喷雾性能与喷雾量、有或没有助剂、喷雾形式和喷雾高度密切相关。研究结果为苹果园植保无人机选择合适的作业参数和喷洒模式提供了理论依据。
