摘　　要：为了节省农药及减少对生态环境的污染,研究喷雾角度、荷电电压、叶片表面性质对静电喷雾施药靶标沉积效果的综合影响,以黄瓜、西红柿、菠菜的叶片作为靶标进行静电喷雾实验,结合实验结果对喷雾角度、荷电电压、叶片表面性质与靶标沉积效果的关系进行分析和讨论。结果表明:随着喷雾角度的增加,荷电雾滴在叶片上的沉积量先升后降,合适的喷雾角度会使3种靶标上的沉积量都增加,对3种叶片最佳喷雾角度都为60°;荷电电压、叶片表面性质对沉积效果影响显著;叶片表面结构是影响作物上药液沉积效果的重要因素。该研究有助于更加合理高效调控静电喷雾系统工况参量,提高雾滴对靶标的有效沉积。In order to save pesticides and reduce environmental pollution, the combined influence of spray angle, charge voltage, and leaf surface proper- ties on the deposition effects of electrostatic spray pesticide was researched with the cucumber, tomato, spinach leaves as the target. According to the test results, with the increasing of spray angle, charged liquid deposition on the leaves first increased and then decreased; Suitable spray angle increased deposition on three kinds of target, and the best spray angle of the three kinds of leaves are 60°; Leaf surface properties and charge voltage have signifi- cant effect on the deposition; Leaf surface structure is an important factor affecting the liquid deposition effects on crops. This study contributes a more rational and effective regulation for the electrostatic spray system parameters, and improves the effective droplet deposition on target.
