摘要
为了研究果园轴流风机风送喷雾机喷雾技术参数对雾滴沉积分布的影响,分别设置了4种喷雾压力、风机出口风速和行驶速度,3种采样高度,对稀疏靶标(沉积架)和仿真树靶标进行了喷雾试验并进行回归分析。试验结果表明,喷雾压力对雾滴沉积无明显影响,减小行驶速度可增加枝叶正反面雾滴的沉积,增大风机出口风速可有效增加雾滴在枝叶反面的沉积;各喷雾技术参数均对冠层内的雾滴沉积覆盖率有显著性影响,其影响程度由强到弱依次为采样高度、行驶速度、风机出口风速、喷雾压力。
In order to research on influence of spray operating parameters on droplet deposition,four kinds of spray pressure,air-blast velocity,travel speed,and three kinds of sampling height,were set to testing droplet coverage in artificial tree canopy and deposition shelf（sparse canopy）,using orchard axial-fan air-assisted sprayer.Results showed that spray pressure had no significant effect on droplet deposition.To reduce travel speed could increase droplet deposition on leaves frontside and backside.To increase air-blast velocity could increase droplet deposition effectively on leaves backside.According to the regression analysis,all the spraying parameters had significant effect on droplets deposition.But influence degree was different,the parameters order from strong to weak by influence degree were sample height,speed,air-blast velocity and spraying pressure.
