| 本研究旨在探究3类植保机械在马铃薯作物上的喷雾效果, 测定其农药利用率以及喷施相同药剂对马铃薯晚疫病防治效果的差异。结果表明, 3种植保机械喷雾雾滴在马铃薯叶片上的密度、覆盖率和沉积量总体表现为上层＞下层, 地面施药机械＞T40植保无人飞机, 农药利用率表现为担架式机动喷雾器(59.37%)＞T40植保无人飞机(25.23%)＞背负式电动喷雾器(23.66%), 3类植保机械喷施相同药剂对马铃薯晚疫病的防效均达到80%以上, 植保无人飞机喷施药剂的作业效率分别是担架式机动喷雾器和背负式电动喷雾器的17.24倍和35.71倍。以上结果表明, 植保无人飞机和担架式机动喷雾器效果较佳, 可根据实际情况优先选择, 该研究为不同植保机械防治马铃薯晚疫病的选择提供科学依据和指导。 |
| 英文摘要: |
| The purpose of this study was to explore the spraying effect of three types of plant protection machinery on potato crops, to determine their pesticide utilization rate, and to assess in their efficacy for controlling potato late blight when applying the same pesticide. The results showed that the density, coverage, and deposition of spray droplets on potato leaves followed the pattern: upper layer>lower layer, ground-based application machinery>T40 plant protection unmanned aerial vehicle (UAV). The pesticide utilization rates were stretcher-type motorized sprayer (59.37%)>T40 plant protection UAV (25.23%)>knapsack electric sprayer (23.66%). The control effects of the same pesticide on potato late blight using the three types of machinery were all above 80%. The operational efficiency of the T40 plant protection UAV was 17.24 times and 35.71 times higher than that of the stretcher-type motorized sprayer and the knapsack electric sprayer, respectively. These results indicate that the T40 plant protection UAV and the stretcher-type motorized sprayer demonstrated better performance and can be prioritized based on practical needs. This study provides a scientific basis and guidance for selecting plant protection machinery to control potato late blight effectively. |
