摘　　要：采用土壤改良剂(YCB-Ⅲ)与农药配施,在减施农药总用量的同时不降低(或提升)对烤烟病毒病的防治效果,且改善烤烟的农艺性状,提高烤烟的产量与品质。从不同处理对烤烟旺长期农艺性状的影响看,T4和T5对烤烟的株高、茎围、有效叶片数、鲜叶重和开片度均达到显著水平。相对于T1,T2、T3、T4和T5的YCB-Ⅲ施用量分别增加了25%、50%、75%和100%,农药施用量分别减少了0.00%、25%、50%和50%,但是防治效果均大于74%,处于同一水平。研究表明,YCB-Ⅲ的施用量525 kg/hm~2、4%嘧肽霉素水剂(KV_1)有效成分施用量120 g/hm~2、0.5%香菇多糖水剂(KV_2)有效成分施用量12.5 g/hm~2为最佳推荐量。In this study,soil conditioner(YCB-Ⅲ)was applied in combination with pesticides to reduce the total amount of pesticides while not reducing or improving the control effect of flue-cured tobacco virus disease,improving the agronomic properties of flue-cured tobacco,and improving the yield and quality of flue-cured tobacco.According to the effects of different treatments on the long-term agronomic traits of flue-cured tobacco,the plant height,stem girth,effective leaf number,fresh leaf weight and slice opening of T4 and T5 reached significant levels,and the YCB-Ⅲ application amount increased by 25%,50%,75% and 100% compared with T1,T2,T3,T4 and T5,respectively.The pesticide application amount was reduced by 0.00%,25%,50% and 50% respectively,but the control effect was greater than 74%,at the same level.The study showed that the application dosage of YCB-Ⅲ was 525 kg/hm^(2),the effective component of 4%Cytosinpeptidemycin SL(KV 1)was 120 g/hm^(2),and the effective component of 0.5% Lentinan SL(KV 2)was 12.5 g/hm^(2).
