烤烟中川208和湘烟7号在攀枝花烟区的适应性研究

Adaptability Study of Flue-cured Tobacco Varieties Zhongchuan 208 and Xiangyan 7 in Panzhihua Tobacco Region

为研究烤烟品种中川208和湘烟7号在攀枝花烟区的适应性,以云烟87作对照,从生育期、农艺性状、经济性状、烟叶化学品质方面进行对比分析。结果表明:中川208和湘烟7号较对照品种云烟87还苗快,长势强,生长迅速,田间表现较好,但易受到高温干旱胁迫,在生产上需备足抗旱用水。这2个品种可适当扩大试种面积,进一步研究其在攀枝花烟区的生态适应性。

In order to study the adaptability of flue-cured tobacco varieties Zhongchuan 208 and Xiangyan 7 in Panzhihua tobacco region,this study used Yunyan 87 as the control,analyzed growth period,agronomic traits,economic traits and tobacco leaf chemical quality.The results showed that Zhongchuan 208 and Xiangyan 7 had faster seedling recovery,stronger growth,and faster growth compared with the control variety Yunyan 87.They performed well in the field,but were susceptible to high temperature and drought stress.Therefore,water used for drought resistance needs to be prepared for production.These two varieties can be appropriately expanded in the trial planting area to further study their ecological adaptability in the Panzhihua tobacco region.
