韶关烟区外引烤烟品种筛选与评价

Screening and Evaluation of Exotic Flue-cured Tobacco Varieties in Shaoguan Tobacco-growing Areas

为了筛选出适宜韶关烟区种植的优质烤烟后备品种,以K326和粤烟97为对照,对外引的5个品种进行田间比较试验。结果表明,参试品种生育期为115~120 d,田间长势粤烟97和安烟一号最好,其他品种与K326较为接近,可采叶数保持在16~18片之间,粤烟97和NC71经济性状优于K326;安烟一号和NC71中部叶总糖和还原糖含量与K326均较接近,烟碱上部叶含量普遍偏高,总氮、钾和氯含量均较适宜,NC102和K326糖碱比均在10左右,化学成分较为协调。总体来看,以粤烟97综合表现最好,NC71可作为后备品种继续开展小面积生产试验进行验证。

In order to screen out high quality flue-cured tobacco varieties suitable for Shaoguan tobacco-growing area, taking K326 and Yueyan 97 as contrasts, 5 varieties of exotic flue-cured tobacco varieties were compared in the field.The results showed that the growth period of the tested varieties was generally at 115-120 days, the growth trend of Yueyan 97 and Anyan 1 were the best, and the other varieties and K326 were closer.The number of recoverable leaves remained from 16 to 18, and the economic characters of Yueyan 97 and N C71 were better than that of K326.The total sugar and reducing sugar content in the middle leaves of Anyan 1 and NCT1 were close with K326,the nicotine content in the upper leaves were generally high, the content of total nitrogen, potassium and chlorine were more suitable, the ratio of sugar to alkali both NC 102 and K326 were about 10, and the chemical composition was more coordinated.Overall, Yueyan 97 has the best performance, NC71 can be used as a backup variety to continue small area production test.
