| 摘 要： | 以丽春红S为示踪剂研究毒死蜱药液在甘蓝叶片上的沉积特性。结果表明,用直径(VMD)为157.3μm的雾滴喷雾较有利于药液在甘蓝叶片上沉积。在雾滴直径149.5μm与每667m~2施药液量12.8L条件下喷雾毒死蜱的沉积量最多,是雾滴直径233.7μm与施药液量46.3L条件下喷雾的1.36倍。每667m~2施药液量25.5L时,毒死蜱在甘蓝叶片上的沉积量达到最大值。

| Abstract: | The retention characteristics of chlorpyrifos droplets on cabbage leaves were detected by using the tracer of ponceau S. The results indicated that the chlorpyrifos droplets were apt to deposit when the droplet size (VMD) was 157. 3 μm. The retention of chlorpyrifos treated with the droplet size of 149.5μm and spray volume 192 L·hm-2 was 1. 36 times more than that treated with droplet size 233.7μm and spray volume 695 L·hm-2. The deposition on cabbage leaves was maximum when the spray volume was 383 L·hm -2... |
