Study on the quality of pesticide spraying distribution based on DGPS technology
Etude de la qualité de la distribution de la pulvérisation à partir de technologies DGPS
Résumé
A solution of rhodamine B dye and water instead of pesticide was used to spray vine trees located using DGPS technologies. Samples of cotton fabrics positioned vertically and horizontally before and behind a tree and the vine leaf samples representing different heights and horizontal distances 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 choosong and adjusting the vine sprayer and in the guidance of accurate spray in precision viticulture;
