摘　　要：农药作为农业生产中不可或缺的生产资料,对全球粮食安全具有重要意义.提高农药利用率的关键在于增强农药与叶片表面间的亲和力、提高在叶片表面沉积和附着能力.本文对农药液滴在植物叶片上的润湿性影响因素进行了分析,综述了农药液滴自身特性(如表面张力和接触角)对其在叶片上形成均匀附着或局部浸润以及沉积率产生的影响,探讨了叶片表面形态(包括微观结构、蜡质层、叶片形状和表面自由能)对其润湿性的影响和纳米农药在植物叶片表面沉积的应用研究.The significance of pesticides to global food security cannot be overstated,as they serve as an indispensable means of production in agricultural practices.The key to enhancing the utilization rate of pesticides lies in optimizing the affinity between pesticides and leaf surfaces,as well as improving their deposition and adhesion capabilities on the leaf surface.Based on this,the factors influencing the wettability of pesticide droplets on plant leaves were analyzed in this paper,and the impact of pesticide droplet characteristics(including surface tension and contact angle)on their uniform adhesion or localized infiltration on leaves and deposition rate were reviewed.Furthermore,the effects of leaf surface morphology,including microstructure,waxy layer,leaf shape,and surface free energy on its wettability were further discussed.Lastly,a comprehensive investigation was conducted on the application of nanopesticides on the plant leaf surface.
