| 摘 要： | 采用大疆MG-1P型电动四旋翼植保无人飞机在棉花生长中期进行喷雾施药处理,探讨了喷雾参数及添加的助剂类型对农药雾滴在棉花植株叶片上沉积分布的影响。以22%氟啶虫胺腈悬浮剂及3种飞防助剂(倍达通、ND-800和G-2801)为试验药剂,在不同喷雾参数及飞防助剂条件下在棉花生长中期进行喷雾处理,以诱惑红作为药剂沉积指示剂,采用雾滴测试卡和滤纸检测雾滴沉积分布情况,利用分光光度计测定滤纸洗脱溶液的吸光度值,计算单位面积的药液沉积量,利用DepositScan软件分析雾滴密度。结果显示:植保无人飞机的飞行速度对雾滴沉积分布的影响最大,而飞行高度则对其无显著影响。添加不同助剂对棉花植株叶片正反面的雾滴沉积分布影响不同:3种助剂均可使棉花冠层上、中、下部叶片正面的雾滴密度显著提高;而对于叶片反面,则仅添加ND-800后棉花冠层上、中、下部叶片反面的雾滴密度分别增长688.9%、590.9%和327.5%,而添加G-2801与倍达通助剂则无显著影响。

| Abstract: | The DJI MG1-P electric four-rotor plant protection unmanned aerial vehicle was used for spraying in the mid-growth-cotton. And the effects of spray parameters and adjuvant type on the deposition and distribution of pesticide mist droplets on cotton plant leaves were discussed. 22% flonicamidonitrile SC and three kinds of spray adjuvants (Beidatong, ND-800, G-2801) were used as test agents, which were sprayed under different spray parameters and different aerial spray adjuvants. As a tracer of pesticide deposition, allura red was employed to detect the distribution of droplet deposition using water sensitive paper and filter paper. The absorbance value of the filter paper elution solution was measured by a spectrophotometer. The absorbance value of the filter paper elution solution is measured by a spectrophotometer in order to calculate the amount of drug solution deposited per unit area, and the droplet density was analyzed by DepositScan software. The test results showed that the flight speed of unmanned aerial vehicle had the greatest influence on the droplet deposition distribution, and the flight height had no significant effect on the experiments using the middle of cotton growth. The adjuvant had a significant effect on the spray deposition distribution. After adding the spray adjuvants, the droplet densities on the upper, middle and lower parts of the cotton canopy were all significantly improved. After adding ND-800 adjuvant, the droplet density on the back of the upper, middle and lower leaves of the cotton canopy increased by 688.9%, 590.9% and 327.5%, respectively. However, the addition of G-2801 and Bidatong adjuvant had no significant effect on the droplet density on the back of cotton leaves. |
