| ［目的］ 筛选出适合茶树病虫害防治的新型喷雾器。［方法］ 对4种喷雾器进行额定喷雾压力下喷头流量、喷雾后雾滴在茶树有效沉积量以及地面流失量的比较试验。［结果］ 静电喷雾器3WBJ 16DZ在0.5 MPa喷雾压力喷雾时喷头流量最大，为1 290 mL/min；在不同高度及距施药者不同距离的雾滴沉积分布比较中，在小区内投放相同质量指示剂的情况下，静电喷雾器3WBJ 16DZ喷雾雾滴的沉积量约为其他3种供试喷雾器喷雾雾滴沉积量的2~3倍，而其地面流失率却小于对照背负式手动喷雾器。［结论］ 通过田间试验测定，静电喷雾器3WBJ 16DZ具有施药液量少、药液沉积量高等特点，适合在茶树上推广使用。 |

| ［Objective］ To screen new sprayers for tea pest control. ［Method］ Four different sprayers were evaluated for the deposition of droplets in tea canopy and on the ground. The spray rate of four different sprayers were evaluated. ［Result］ The spray rate of electrostatic sprayer 3WBJ 16DZ was 1 290 mL/min in 0.5 MPa. The droplet deposition of electrostatic sprayer 3WBJ 16DZ was about 2-3 times as that of the other three sprayers at different heights and in different distances. The run off of electrostatic sprayer 3WBJ 16DZ was obviously less than that of the lever operated knapsack sprayer. ［Conclusion］Field experiments showed that the electrostatic sprayer 3WBJ 16DZ was characterized by strong adhesion rate, which was quite feasible for use in the tea garden. |
