| 摘 要： | 使用药液沉积变异系数Cv、农药有效利用率、地面药液沉积率和飘失率作为衡量指标,对比常用喷枪、改进喷枪和果园自动对靶喷雾机的施药效果进行研究。研究结果表明:改进喷枪和果园自动对靶喷雾机都能提高药液在果树冠层中的沉积均匀性,减少药液在地面的流失量,果园自动对靶喷雾机效果最佳。改进喷枪比常用喷枪的施药效果略有提高,果园自动对靶喷雾机会显著提高药液沉积均匀性和农药利用率。

| Abstract: | The coefficient of variation (Cv), pesticide efficacy, ground deposition rate and drift rate were used to measure the spraying quality of a normal spraying gun, a modified spraying gun and a automatic target detecting orchard sprayer. Result confirmed that both the modified spraying gun and automatic target detecting orchard sprayer could improve the uniformity droplets deposition in canopy and decrease the volume of the pesticide running to ground. Comparisons among three orchard plant protection equipments showed that the modified spraying gun improved the spraying quality a little and the automatic target detecting orchard sprayer got the best result by significant improving on the uniformity of deposition and pesticide efficacy. |
