摘要
以K326为材料,设置5个移栽期:处理1(3月4日)、处理2(3月9日)、处理3(3月14日)、处理4(3月19日)和处理5(3月24日),研究了移栽期对烟叶化学成分和中性香气成分的影响。结果表明,随着移栽期的推迟,糖碱比、氮碱比均增大,其中以处理5的总糖、还原糖含量最高,极显著地高于其它处理;类西柏烷类和类胡萝卜素类致香物质也随移栽期推迟而呈下降趋势,致香物质总和以处理1最高,处理5最低,处理2处于中等水平,由大到小依次为处理1、处理4、处理2、处理3、处理5。可见,提前移栽有利于浓香型烟叶品质的形成,过晚移栽则烟叶品质较差。抚州市烤烟最佳移栽期在3月4—9日。
In order to study the effects of different transplanting periods on chemical composition and neu- tral aroma components of tobacco, K326 was taken the as material and 5 transplanting dates, namely, treatment 1 （ March 4th ）, treatment 2 （ March 9th）, treatment 3 （ March 14th）, treatment 4 （ March 19th） and treatment 5 （March 24th）.The results showed that,with the delaying of transplanting dates ,both sugar alkali ratio and ni- trogen bases ratio increased,among which treatment 5 possessed the highest total sugar and reduced sugar,it was significantly higher than those of other treatments ; cembratriendiol and carotenoids showed a decrease trend with transplanting dates delayed.Treatment 1 had the highest total aroma content, treatment 5 had the lowest, treatment 2 had the medium, the performance was in the descending order of T1, T4, T2, T3, T5.Obviously, ear- lier transplanting is good for the formation of highly flavored type tobacco, late transplanting causes low quality. The best transplanting date in Fuzhou were from March 4th to March 9th.
