摘要: 为评估3CG-45型茶园管理机的喷雾性能,本试验利用水敏纸测试了该机器的雾滴雾化效果,利用诱惑红水溶液作为示踪剂研究该机器的雾滴沉积分布,并进行了田间药效评价试验。结果表明,3CG-45型茶园管理机的雾滴细,单位面积内雾滴数多于常规背负式喷雾器,茶树1/2高度正面45°处,3CG-45型茶园管理机的雾滴在水敏纸上印痕直径为(300.24±157.23)μm,雾滴密度为(141.25±23.85)个·cm-2。雾滴在茶树上部、中部、下部及地表的诱惑红沉积量分别为(0.64±0.14)μg·cm-2、(0.20±0.05)μg·cm-2、(0.18±0.03)μg·cm-2和(0.14±0.02)μg·cm-2。田间药效试验结果显示,3CG-45型茶园管理机在农药剂量减少的情况下,防治效果仍然高于常规背负式喷雾器,适用于茶园病虫害喷雾防治。

Abstract: To evaluate the spray performance of 3CG-45 management machine, we used water sensitive paper test the droplets atomization effect and used allure red solution as tracer to investigate droplets deposit and distribution, finally, 3CG-45 management machine’s field efficacy trial was evaluated. The results showed the droplets of 3CG-45 management machine were smaller than Nongbang WBS-16 manual sprayer and the number of droplets were more than Nongbang WBS-16 manual sprayer in the same unit area. The droplet diameter on 45o front in half height of tea plant is (300.24±157.23) μm, droplets density is 141.25±23.85 per square centimeter. The deposition of allure red solution on upper, middle, lower and bottom is respectively (0.64±0.14) μg·cm-2, (0.20±0.05) μg·cm-2, (0.18±0.03) μg·cm-2 and (0.14±0.02) μg·cm-2. The result of field efficacy trial showed 3CG-45 management machine possesses good control effect even pesticide dose was reduced. In conclusion, 3CG-45 management machine showed good spray function to control tea diseases and insect pests.
