摘要
针对篱壁式种植葡萄缺乏病虫害防治专业施药机具,农药利用率低等问题,设计了能够将未沉积在靶标上的农药雾滴截留回收再利用的"Π"型循环喷雾机,并测试了该喷雾机的药液回收率与冠层中药液沉积分布状态。结果显示:两侧喷杆交错喷雾和喷头上仰能够提高药液回收率44.0%和18.4%,并能够增加冠层内部与叶片背面药液沉积量。栅格端面罩盖能够有效改变气流方向,提高药液回收率10%以上。
Aiming at the shortcomings of specialized plant protection machinery for trellised vine and the low-level efficiency of pesticide application,a Π-type recycling tunnel sprayer for the liquid that was not retained by the leaves was developed.Spray recycling and deposit in canopy were measured.Results showed that it could increase chemical recovery rate up to 44.0% and 18.4% respectively and increase the deposition on the underside of leaves and leaved inside canopy by assembling booms interlaced and turning nozzles upward.Grid end shield could deflect air direction effectively to increase chemical recovery rate more than 10%.
