通过 DGPS对葡萄树定位 ,应用气助喷雾器将 Rhodam ine- B染料与水混合的溶液代替农药喷施在葡萄树中 ,取葡萄树高度和深度方向所在区域的葡萄叶片样品 ,以及葡萄树的前、后高度方向和地表面宽度方向的棉织品样品 ,对这些样品的喷雾沉积量进行测定及对葡萄叶片样品的面积进行计算 ,作出了有关分布曲线以及分布图。 The grapevines were positioned by DGPS, and the solution mixed with Rhodam ine-B dye and water was sprayed on the vines instead of the pesticides using the gas-assist atomizer. The grapevine leaf samples in the region where the vines were located in the height and depth direction, , The height direction and the width direction of the ground surface, the spray deposition amount of these samples was measured, and the area of ​​the grape leaf sample was calculated, and the distribution curve and the distribution map were made.
