[目的]确定信阳烟区适宜的烤烟移栽期,为提高信阳烤烟产量及质量提供依据。[方法]于2012年在信阳市平桥区采用随机区组设计,进行田间不同移栽期试验。[结果]在移栽后45、75 d时,株高以处理T4最高,但其其他指标较低,成熟期以处理T2、T3农艺性状综合最优;烟叶烤后外观质量以处理T3最优,处理T2次之;总糖、还原糖、淀粉含量以处理T4表现最低,但其全氮、烟碱含量偏高;感官评吸质量以处理T3得分最高,处理T4得分最低。[结论]信阳烟区最适合的移栽期是4月20日~4月30日。
[Objective] The research aimed to determine the suitable transplanting period of flue-cured tobacco in Xinyang tobacco-growing area and provide the basis for improving the yield and quality of flue-cured tobacco in Xinyang. [Method] In 2012, a randomized block design was conducted in Pingqiao District, Xinyang City to test the field transplanting period. [Result] At 45 and 75 d after transplanting, the plant height was the highest in treatment T4, but the other indexes were lower, and the agronomic traits were the most suitable in treatment of T2 and T3 in mature stage. , Followed by T2. The content of total sugar, reducing sugar and starch in treatment T4 was the lowest, but the content of total nitrogen and nicotine was high. The sensory evaluation of smoking quality was the highest in treatment T3 and the lowest in treatment T4. [Conclusion] The most suitable transplanting period in Xinyang tobacco-growing area was from April 20 to April 30.
