摘　　要：[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 ] To study the optimal transplant date in Xinyang flue-cured tobacco area, provide reference for improving flue-cured tobacco quality. [ Method] The field experiment of transplant date with randomized block was conducted in Pingqiao area, Xinyang City in 2012. [ Result] The result showed that, plant height of T4 treatment was highest but other index were lower in days after transplant date of 45 and 75, but the agronomic trait of T2 and T3 were better than T1 and T4 in mature period ; appearance quality of tobacco leaf of T3 after curing was best, meanwhile, T2 was second; total sugar, reducing sugar and starch content of T4 were lowest but total nitrogen and nicotine were higher; sensory evaluation quality of tobacco leaf of T3 was best,T4 was worst. [ Conclusion ] The optimal transplant date for flue-cured tobacco in Xinyang is during April 20 -30.
