茶树;小绿叶蝉;吹雾法;喷雾法;防效
摘  要：
吹雾法雾滴平均粒径为77.5微米,雾滴数多,均匀度好,VMD/NMD为1.3,农药在茶树上沉积率高达72.8％,比常规喷雾法高1.4倍,地面流失率和空中飘移率比常规法减少1.5倍。吹雾法对防治茶树小绿叶蝉比常规法节省农药40～50％,省水90％以上,提高施药工效2～3倍。

摘  要：
Atomization by a new atomizer could maie fine chemical droplets with a diameter of 77.5μm, the result of more droplets and higher homogeneous degree. The ratio of VMD/NMD was 1.3. The deposition ratio of chemicals on tea bush was as high as 72.8%, and 1.4 times higher than that by deneral spraying. The seeping ratio on the ground and drifting ratio in the air were 1.5 times less than that by normal spraying. The way saved chemical 40-50% and water 90% for control Empoasca flavescns Fabricius, and raised efficiency of applying chemical.
