基于DGPS的农药喷施分布质量的研究

Study on the Quality of Pesticide Spraying Distribution Based on DGPS Technology

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。

A solution of Rhodamine B dye and water instead of pesticide was used to spray over the vine trees located using DGPS technology. The samples of cotton fabrics positioned vertically and horizontally before and behind a tree and the vine leaf samples representing different height and horizontal distance respectively were collected to measure the quantity of spray deposit and calculate the area of vine leaf samples. As a result, a series of distribution curves and maps were plotted. The results had great positive significance in choosing and adjusting a vine spray instrument, and in the guidance of pesticide accurate spray in precision viticulture.
