Primary Studies on Optimal Application Parameters for UAV to Spray the Growth Regulator of Pueraria Lobata
摘要
Abstract
The optimal operation parameters combination of unmanned aerial vehicle(UAV)in the growth regulation ap-plication of Pueraria lobata was explored to promote the application of UAV in Pueraria lobata plant protection operation,and raise the mechanized operation level of Pueraria lobata planting industry.The droplet deposition on the Pueraria loba-ta leaf and the growth regulation effect on the main vine stem of Pueraria lobata after UAV spraying paclobutrazol under different operation parameter combinations were studied using four factors(flight speed,flight height,spray volume,spray concentration)and three levels orthogonal tests.The results showed that the primary and secondary factors affecting the droplet deposition were flight speed,spray volume,spray concentration and flight height in turn,and a larger droplet deposition could be obtained when the flight speed was 3 m/s,spray volume was 17.91 L/hm2,spray concentration was 0.6％,and the flight height was selected at the lowest level.From the perspective of the growth regulation effect on the main vine stem of Pueraria lobata,the spray concentration and flight height had a greater impact on the growth regulating effect of the third day after spraying,while the spray concentration,spray volume and flight height had a greater impact on the eighth and fifteenth days,and the effect of the spray concentration was always at a very significant level.The actu-al efficacy of paclobutrazol showed an overall strengthening trend with the passage of time within 15 days after spraying.On the fifteenth day after spraying,the elongation of main stems and vines in the treatment group with the spray concen-tration of 1.2％decreased by more than 60％compared with the blank control group.When the flight height was 2.3 m,the spray concentration was 1.2％,the spray volume was 17.91 L/hm2 and the lowest flight speed was selected,a better growth regulation effect was obtained.Integrated the droplet deposition and the growth regulation effect on the main vine stem of Pueraria lobata,the optimal operation parameters combination was preliminarily found out as follows:flight speed of 3 m/s,flight height of 2.3 m,spray volume of 17.91 L/hm2,and the spray concentration of 1.2％.The results of this study can provide reference and guidance for the rational setting of UAV operating parameters during the growth regu-lating applications of Pueraria lobata.关键词
