摘要
采用水敏纸法分析雾滴分布,利用诱惑红示踪结合分光光度计测定沉积量,并计算农药利用率。结果表明,自走式喷杆喷雾机药滴沉积量和覆盖率分别为3.18μL/cm~2和4.99%,为最高;植保无人机雾滴体积中径为137.12μm,是3种药械中最小。背负式静电喷雾器在白菜苗期、莲座期和结球期的农药利用率分别为26.05%、34.81%和53.60%;自走喷杆喷雾机在白菜莲座期的农药利用率为46.37%;植保无人机在结球期的农药利用率为60.41%。研究表明,在白菜莲座期,自走式喷杆喷雾机比背负式静电喷雾器农药利率提高11.56个百分点;在结球期,植保无人机比背负式静电喷雾器农药利用率提高6.81个百分点。
In this paper,the water sensitive paper method was used to analyze the distribution of droplets,the amount of deposition was determined by allure red tracer combined with spectrophotometer,and the utilization rate of pesticides was calculated.The results show that the droplet deposition rate and coverage rate of self propelled sprayer are 3.18μL/cm~2 and 4.99%respectively,and the maximum diameter of plant protection UAV droplet is 137.12μm,which is the smallest among 3 kinds of The pesticide utilization rate of knapsack electrostatic sprayer in cabbage seedling stage,rosette stage and heading stage was 26.05%,34.81%and 53.60%respectively.The pesticide utilization rate of self propelled sprayer in cabbage rosette stage was 46.37%,and the pesticide utilization rate of plant protection UAV during heading stage was 60.41%.The results showed that in the rosette stage,the self propelled boom sprayer increased by 11.56 percentage points than the backhand electrostatic sprayer,and the pesticide utilization rate of the plant protection UAV was 6.81 percentage points higher than that of the knapsack electrostatic sprayer at the heading stage.
