两种喷撒技术雾滴在花椰菜上的沉积分布研究

在花椰菜莲座后期，测定了低容量吹雾法和高容量喷雾法雾滴在花椰菜上的沉积分布。结果表明，两种喷撒技术形成的雾滴在叶片上的单位面积沉积量均以中层叶较高，内层与外层叶上较低；但吹雾法雾滴在内层和中层叶上的沉积量明显比喷雾法高，在中层叶背面的沉积机率亦比后者大。

The Deposit and Distribution of Droplets on Cauliflower Leaves by Two Kinds of Spraying Techniques

The deposit and distribution of droplets emlnitted from low volume sprayer(LVS)and high volutne sprayer(HVS)on cauliflower leaves were determined at later rosette stage,The results showed that both high deposit rat(μg/cm2)on the leaves at middle strata and low at inner and outer strata. The droplets emmitted from LVS had compared with those emmitted from HVS.The deposit rate of LVS on the leaves at inner and middle strata,were obviously higher and relatively easier than HVS’deposited on the back of the leaves at middle strata.
