不同烤烟品种农艺性状与经济性状的差异研究

The Differences of Agronomic and Economic Characters in Different Flue-cured Tobacco Cultivars

为了筛选特定生态条件下最适宜种植的烤烟品种,于2014年在湖南芷江对毕纳1号、云烟87、NC71、NC297、红花大金元、0508、K326等7个烤烟品种进行了比较试验。结果表明:供试7个烤烟品种中,K326与云烟87的综合农艺性状表现较好;0508和云烟87两个烤烟品种的主要化学成分含量较适宜;上等烟比例以毕纳1号最高(大于50%)。供试7个烤烟品种的产量依次为云烟87、0508、K326、NC71、毕纳1号、NC297,产值依次为云烟87、毕纳1号、K326、0508、NC297、NC71。综合经济性状各指标以云烟87最好,毕纳1号次之,NC71的最差。综合7个供试烤烟品种各性状分析结果,以云烟87与毕纳1号的表现最好。

To screen the most suitable planting flue-cured tobacco cultivars in specific ecological conditions,seven flue-cured tobacco cultivars,Bina 1,Yunyan87,NC71,NC297,Honghua Dajinyuan,0508,K326,were compared in 2014 in Hu-nan Huaihua Zhijiang County.The main research results are as follows.In the tested 7 flue-cured tobacco cultivars,K326 and Yunyan 87 of flue-cured tobacco cultivars were better comprehensive agronomic performance.The main chemical com-position contents in 0508 and Yunyan 87 of flue-cured tobacco cultivars are appropriate,the that of 1th Bina was the sec-ond,the that of NC71 is not coordinated.The upper tobacco ratio of the 1th Bina is the highest (greater than 50%).The appearance quality of tobacco in the 1th Bina,,NC71 and Yunyan 87 is better.The yields of the tested 7 flue-cured tobacco cultivars was as Yunyan 87 >0508 >K326 >NC71 >the 1th Bina >NC297.The output value was as Yunyan 87 >the 1th Bina >K326 >0508 >NC297 >NC71.The comprehensive economic traits of Yunyan 87 were best,the that of the 1th Bina was the second,the that of NC71 was the lowest.The comprehensive analysis results of different traits in the 7 tested flue-cured tobacco cultivars,the comprehensive performance of Yunyan 87 and the 1th Bina was the best.
