Spraying Mode Optimization of Multi-rotor Plant Protection UAV for Precision Prevention and Control in Differentiated Orchards
摘要
Abstract
Aiming to address the poor adaptability of plant protection UAV spraying modes,uneven canopy deposition,and increased ground loss risk caused by complex terrain and heterogeneous canopy structures in orchard pest and disease control,spraying mode decision-making and parameter optimization for precision orchard plant protection were investigated.Plain high-spindle orchards and mountainous open-center orchards were selected as typical application scenarios.Multi-source information,including terrain type,canopy structure,flight mode,droplet coverage,droplet density,deposition uniformity,and ground deposition,was integrated to establish an operation-mode evaluation and decision-making method for the spraying execution layer.The effects of intra-row,inter-row,and spiral flight modes on canopy droplet deposition and ground loss were systematically analyzed.The results showed that in plain high-spindle orchards,the inter-row flight mode enhanced droplet penetration into the canopy,with an average droplet density of 32.52 droplets/cm2 and a coefficient of variation of 14.64％,outperforming the intra-row and spiral modes.Therefore,it was recommended as the preferred spraying mode for pest and disease control in dense plain orchards.In mountainous open-center orchards,the spiral flight pattern achieved higher droplet deposition and superior coverage performance.The droplet density on the adaxial and abaxial leaf surfaces ranged from 56.42 droplets/cm2 to 88.18 droplets/cm2 and 25.29 droplets/cm2 to 67.38 droplets/cm2,making it more suitable for improving pesticide coverage in open-center structures.Although the inter-row and spiral modes improved canopy deposition,they also increased ground deposition to some extent.The research findings can provide theoretical guidance and technical support for pesticide application decisions on the intelligent pest and disease management platform for orchards.关键词
