摘要

在现场进行了研究,以测量不同应用(喷嘴/液滴大小和臂架高度)和气象条件下喷雾剂的脱靶喷雾沉积率。对结果进行了分析,探讨了喷雾质量、臂架高度和风速对喷雾沉积速率的影响。所呈现的曲线表明,细喷雾的沉积速率大于中至超粗喷雾,并且悬臂高度较大。沉积速率和风速之间没有很强的相关性。这可能主要是由于第一个采样位置距离应用区域边缘25英尺(7.5米)相对较远,并且研究中的大多数风速大于<10英里/小时(<16公里/小时),风速影响最有可能最明显。

Analyses of Equipment, Meteorology and Other Factors Affecting Drift from Applications of Sprays by Ground Rig Sprayers
Studies were conducted in the field to measure off-target spray deposition rates from applications of sprays under different application (nozzle/droplet size and boom height) and meteorological conditions. The results were analyzed to investigate the effects of spray quality, boom height and wind speed on spray deposition rates. Curves are presented showing that deposition rates were greater for fine sprays than medium to extra coarse sprays, and for greater boom heights. There was not a strong correlation between deposition rates and wind speed. This was probably due mainly to the relatively far distance of the first sampling location at 25 ft (7.5 m) from the edge of the application area, and to the fact that most of the wind speeds in the studies were greater than the <10 mph (<16 km/hr) where wind speed effects would be most likely to be most evident.
