采用田间小区试验的方法,进行了静电电动喷雾器与普通电动喷雾器防治蔬菜害虫的效果和单位面积药液用量的对比试验。结果显示:1选用5种生物药剂采用叶面喷雾施药防治斜纹夜蛾、小菜蛾和菜青虫3种害虫,静电电动喷雾器施药处理平均死亡率为86.48%,通电动喷雾器施药处理的平均死亡率为83.56%。统计分析表明:静电电动喷雾器施药处理与普通电动喷雾器施药处理之间,害虫死亡率差异不显著。2静电电动喷雾器施药,药液用量为15L/667m~2,采用普通电动喷雾器施药,药液量为60L/667m~2。采用静电电动喷雾器比普通电动喷雾器施药减少药液量45L/667m~2,即节约药液量75%。表明在害虫死亡率相当的前提下,静电电动喷雾器施药处理显著提高了药液和药剂的使用效率,可节省大量人力物力。
The method of field plot test was used to compare the effect of electrostatic atomizer and common electric sprayer in controlling vegetable pests and the dosage of liquid per unit area. The results showed that: 1 Five kinds of biological agents were selected to control three kinds of pests, Spodoptera litura, Plutella xylostella and Pieris rapae by foliar spraying. The average death rate of electrospray sprayer was 86.48% The mortality rate was 83.56%. Statistical analysis shows that there is no significant difference in the mortality rate of pests between the application of electrostatic atomizer and ordinary electric sprayer. 2 Electrostatic sprayer application, the amount of liquid 15L / 667m ~ 2, the use of ordinary electric sprayer application, the amount of liquid 60L / 667m ~ 2. The use of electrostatic electric sprayer to reduce the amount of liquid 45L / 667m ~ 2 than ordinary electric sprayer, which saves 75% of the amount of liquid. The results showed that under the premise of considerable pest mortality, the electrostatic atomizer application treatment significantly improved the efficiency of the liquid and medicament, saving a lot of manpower and material resources.
