摘　　要：评价了飞防弥雾机不同喷液量和助剂种类在山地板栗树冠层的雾滴分布情况,并比较了其对栗大蚜和红蜘蛛的防治效果,旨在为板栗害虫化学防治提供技术支持。结果表明,在一定范围内提高喷液量,并添加喷雾助剂,对喷雾质量有一定的增益效果。在5.0 L/667m^2喷液量条件下,添加1%倍达通喷雾助剂处理的雾滴中径为121.7μm,显著高于无助剂处理的96.0μm;同时,雾滴密度、覆盖度、沉积量及对栗大蚜和红蜘蛛的防效均显著提高。In this experiment,we evaluated the droplets distribution in chestnut canopy of mist sprayer with different spray volume and adjuvant types,and the control effects on Lachnus tropicalis and spider mites were compared,to provide technical support for chestnut pest chemical control.The results show that,the increase of spray volume and the addition of adjuvant in a certain range have a certain gain effect on spray quality.With spray volume 5.0 L/667m^2,DV50 of droplets treated with 1%Beidatong adjuvant were 121.7μm,which were significantly higher than 96.0μm of no auxiliary treatment.At the same time,the droplet density,coverage rate,deposition and the control effect on Lachnus tropicalis and spider mites were all significantly improved.
