石柱县烤烟新品种适应性评价

Adaptability Evaluation of New Flue-cured Tobacco Varieties in Shizhu County

为筛选出适宜石柱县的烤烟品种,对遵烟6号、湘烟5号、CF8704、改良K326和云烟87(对照)在生育期、植物学性状、农艺性状、经济性状等方面进行比较。结果表明,CF8704具有早生快发的优势,前期生长势强,农艺性状整体表现相对适宜,经济性状指标显著高于其他品种,具有在石柱县进一步推广的价值。遵烟6号、湘烟5号叶片数多,经济性状也好于云烟87(CK),但上部叶不易成熟落黄,烤后杂色烟较多,建议进一步考证观察。改良K326不太适宜石柱高海拔地区气候特征,不建议在石柱高海拔地区推广。

In order to screen out suitable flue-cured tobacco varieties in Shizhu County,we compared growth period,agronomic traits,botanical traits,economic characters of Zunyan 6,Xiangyan 5,CF8704,improved K326 and Yunyan 87.Results showed that CF8704 had the value of further promotion in Shizhu County due to the advantages of rapid growth,the strong growth potential in the early stage,relatively suitable agronomic characters and the significantly higher economic character indexes.Zunyan 6 and Xiangyan 5 had more leaves,and better economic characters than Yunyan 87(CK),but the upper leaves were not easy to mature and turn yellow,and there were more motley leaves.Therefore,further research and observation were suggested.The improved K326 was not suitable for the climatic characteristics of the high altitude area of Shizhu County,so it was not recommended to be popularized in the high altitude area of Shizhu County.
