易门县不同烤烟品种适应性研究

Study on Adaptability of Different Flue-Cured Tobacco Varieties in Yimen County

摘要: 为改善易门烟区因长期种植单一烤烟品种导致的品种退化、产质量下降等问题，以K326为对照，云烟116、云烟100、云烟97及云烟121这4个烤烟品种为研究对象，采用对比分析法，从植物学性状、大田生育期、农艺性状、初烤烟叶外观品质及经济性状等方面研究了4个品种在易门烟区的适应性。结果表明4个烤烟品种的植物学性状、农艺性状、初烤烟叶外观质量和经济性状均优于当地主栽品种K326，可以在易门烟区进一步示范验证，其中云烟121的综合表现最好，田间表现较佳，烟叶产量和产值高。

Abstract: In order to improve the variety degradation and yield quality decline caused by long-term planting of single flue-cured tobacco variety in Yimen tobacco-growing area, K326 was taken as the control, Yunyan 116, Yunyan 100, Yunyan 97 and Yunyan 121 were taken as the research objects by comparative analysis method. The adaptability of four varieties in Yimen tobacco-growing area was studied from the aspects of botanical characters, field growth period, agronomic characters, appearance quality and economic characters. The results showed that the botanical characters, agronomic characters, appearance quality and economic characters of the four flue-cured tobacco varieties were better than that of the local main variety K326, which could be further demonstrated in Yimen tobacco-growing area. Yunyan 121 had the best comprehensive performance, better field performance and higher tobacco yield and output value.
