皖西烟区烤烟新品种适宜栽培技术研究

Study on Suitable Cultivation Technology of New Flue-cured Tobacco Variety in West Anhui

[目的]探索适宜在皖西烟区推广栽培的烤烟品种及栽培技术。[方法]采用裂区设计,以施氮量为主因素,品种为副因素,对3个烤烟品种不同处理的主要农艺性状、经济性状及内在化学成分进行分析。[结果]品种9601表现出明显的早发趋势,较云烟87和云烟85田间长势强。3个品种在当地生态条件下最适宜的施氮水平为97.5 kg/hm2;而在3个处理当中尤以品种9601的综合经济性状表现突出,明显优于其他2个品种,适宜在皖西烟区推广栽培。适当增加钾肥的施入量将更加有利于烟叶内在化学成分的协调。[结论]该研究为皖西烟区烤烟品种的更新换代提供了技术基础。

[Objective] The aim was to explore the flue-cured tobacco variety and the cultivation technology suitable for popularization and cultivation in the tobacco area in west Anhui.[Method] The split plot design was applied and with the nitrogen application amount as main factor and variety as secondary factor,the main agronomic characters,economic characters and intrinsic chemical composition of 3 flue-cured tobacco varieties with different treatments were analyzed.[Result] The variety 9601 showed obvious premature trend and its field growth vigor was stronger than that of Yunyan 87 and Yunyan 85.The most suitable nitrogen level of the 3 varieties was 97.5 kg/hm^2 under the local ecological condition.Among the 3 varieties,the comprehensive economic characters of the variety 9601 were prominent,which was better than that of the other two varieties and was suitable for popularization and cultivation in the tobacco area of west Anhui.Adding proper application amount of potassium fertilize was helpful for coordinating the intrinsic chemical composition of tobacco leaf.[Conclusion] The research provided the technological basis for the renewal of tobacco variety in the tobacco area of west Anhui.
