【摘要】 针对植保无人机喷雾时药液雾滴在复杂的田间作业环境中极易受到风速，温湿度及无人机等施药设备因素影响导致药液雾滴飘移的问题。对雾滴飘移的特点及影响因素和目前国内外飘移雾滴的检测方法和雾滴飘移检测技术的研究进展进行综述。总结雾滴飘移特点及植保无人机进行施药决策前需要整体考虑各方面因素。针对雾滴飘移检测技术发展提出展望，为提高农药利用效率及保护农业环境提供基础参考。更多还原

【Abstract】 Aiming at the problem that the liquid spray droplets of the chemical liquid in the complex field operation environment are very susceptible to the influence of wind spe-ed, temperature and humidity and the spraying equipment factors such as the UAV, resulting in the drift of the liquid droplets. The characteristics and influencing factors of droplet drift,as well as the current detection methods of drifting droplets at home and abroad and the research progress of droplet drift detection technology are reviewed. Summarize the characteristics of droplet drift and the overall consideration of various factors before the plant protection UAV pesticide application decision. The prospect of fog droplet drift detection technology is proposed, which provides a basic reference for improving the efficiency of pesticide utilization and protecting the agricultural environment.更多还原
