Study on parameter optimization and stability of UAV-based plant protection and fertilization operations in lotus root fields
摘要
Abstract
In response to the problems of high labor intensity,low operational efficiency,susceptibility to plant damage,and uneven deposition of pesticides and fertilizers associated with traditional plant protection and fertilization methods in lotus root fields,systematic experiments were conducted to optimize operational parameters and evaluate the performance stability of agricultural UAVs for these tasks.For plant protection operations,a DJI T25 UAV was employed,with trials carried out at varying operational heights(5,6,7 m),operational speeds(4,5,6 m/s),and spray flow rates(2.0～4.2 L/min)to measure droplet deposition amount,deposition density,uniformity,and penetration on both the upper and lower surfaces of lotus leaves.The results indicated that under the conditions of a 6 m operational height and a 5 m/s operational speed(Treatment Group 5),the overall performance of droplet deposition and distribution was optimal:the deposition amount on the lower leaf surface reached 1.05 μL/cm2,the penetration rate was 66.04％,and the uniformity on the upper leaf surface was 78.62％.For fertilization,a DJI T60 UAV was used to conduct compound fertilizer spreading tests under different operational heights(5,6,7 m)and operational speeds(6,7,8 m/s).The deviation in the actual fertilizer application rate and the stability of the operational swath width were determined.The findings revealed an average deviation in the actual application rate of-2.0 kg/667 m2,corresponding to an error rate of 9.5％.The average actual operational swath width was 6.82 m,with a deviation of-0.18 m from the theoretical value and a coefficient of variation of only 4.3％.The combination of a 6 m height and a 7 m/s speed demonstrated the best performance.This research demonstrated that UAV operations can significantly enhance the efficiency,precision,and uniformity of plant protection and fertilization in lotus root fields,while also preventing plant damage caused by manual field entry,highlighting their substantial potential for widespread application and promotion.关键词
