不同烤烟品种适宜留叶数研究进展

分析了部分国内烤烟主栽品种及新品种的适宜留叶数研究进展,结果表明:综合产量、均价、产值以及中上等烟比例来看,主栽烤烟品种的适宜留叶数基本集中在18～23片/株,部分新品种达到24片;地区不同、烤烟品种不同,具体适宜留叶数不同;在适宜留叶数的基础上,各烟区应根据自身不同的气候和品种特性,通过小面积试验研究在有效留叶数基础上进一步摘除下部发育不良烟叶和顶叶的片数及时机,以达到真正优化烟叶等级结构的目的。

Research Progress of the Appropriate Number of Remained Leaves for Different Tobacco Varieties

The research progress of appropriate number of remained leaves of the important domestic varieties and new varieties flue-cured tobacco was analyzed.The results showed that： seeing from total yield,mean price,output value and above-average tobacco percentage,the appropriate number of remained leaves of main flue-cured tobacco mainly are 18-23 leaves per plant,several new varieties are up to 24.The specific appropriate number of remained leaves is different in different regions and varieties.On the basis of appropriate number of remained leaves,according to different climates and variety features,the lower part underdeveloped tobacco leaves and tip leaves were removed,so as to optimize tobacco leaves grade structure.
