新型茶园管理机的农药雾滴沉积特性及田间药效评价
Pesticide Deposit Characteristics and Its Field Efficacy Evaluation of A New Type of Tea Management Machine
摘要
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.关键词
