狭缝式喷头中间有一条狭窄的狭隙与出水孔相连。计有10种型号,适用于手动喷雾器的有4、5、6、7号四种。 1983年秋播期间,我们在付安、三仑两镇作了狭缝式喷头喷洒除草剂的试验示范,取得了满意的结果。实践证明,它比常规喷头(孔径1—1.3mm)具有如下优点: 1.施药质量高,防效好。狭缝式喷头喷出的药液,液滴大而集中,沉降快,受风力影响较小,使药剂能均匀地在喷幅内分布。在相同药量水量下,防除杂草的效果,比常规喷头提
A narrow slot in the middle of the slit nozzle connects to the outlet. There are 10 kinds of models, suitable for manual sprayer are 4, 5, 6, 7, four. During the autumn broadcast in 1983, we piloted the demonstration of spraying the herbicide with slit nozzle at Fu’an and Sanlun towns and achieved satisfactory results. Practice has proved that it has the following advantages over the conventional nozzle (aperture 1-1.3mm): 1. High-quality application, good control effect. Slit nozzle spray liquid, large and concentrated droplets, rapid settlement, less affected by the wind, so that agents can be evenly distributed within the spray width. In the same amount of water under the amount of weed control effect than conventional nozzle mention
