为评价超低容量静电喷雾器施药对贵州省湄潭县茶树主要病虫害的防效,分别使用超低容量静电喷雾器、机动喷雾器、背负式手动喷雾器喷施5.7%甲氨基阿维菌素苯甲酸盐水分散粒剂+15%茚虫威乳油+5%多抗霉素水剂,进行了防治茶树病虫害作业。超低容量静电喷雾器施药后7 d对茶饼病的防效为89.11%,药后15 d对茶假眼小绿叶蝉、茶棍蓟马、茶黑刺粉虱、茶蚜和茶黄螨的防效分别为93.99%、91.44%、91.12%、90.61%和90.00%,均显著高于其他处理的防效。与机动喷雾器、手动喷雾器相比较,静电喷雾器作业效率分别提高了1.67倍、7.00倍,用水量也大幅降低。
To evaluate the control effect of ultra-low-volume electrostatic sprayers on the main pests and diseases of tea plantation in Meitan County, Guizhou Province, the super-low-capacity electrostatic sprayers, mobile sprayers and knapsack sprayers were sprayed with 5.7% emamectin benzoate Dispersible granules + 15% indoxacarb EC + 5% polyoxin antibacterial agent, carried out prevention and control of tea plant diseases and insect pests operations. The anti-caking effect of the ultra-low-capacity electrostatic atomizer on cakes was 89.11% at 7 days after spraying. After 15 days of spraying, the effects of spraying on green tea leafhopper, green tea leaf thrips, The control effects were 93.99%, 91.44%, 91.12%, 90.61% and 90.00%, respectively, which were significantly higher than those of other treatments. Compared with the mobile sprayer and the manual sprayer, the operating efficiency of the electrostatic sprayer increased by 1.67 times and 7.00 times, respectively, and the water consumption also dropped significantly.
