中文摘要：
为了确定临沧市双江县烟区适宜的烤烟移栽期，提升烟叶品质，在临沧市双江县进行了不同移栽期（5月1日前后2 d、5月7日前后2 d、5月15日前后2 d）对烤烟生长发育、经济性状和品质的影响研究。结果表明：随移栽期推后，烤烟封顶后烟株农艺性状、经济性状与烟叶品质均下降，表现为株高降低，平均叶面积变小，上等烟比例和均价下降；烟叶常规化学成分的综合评价指数变化不明显，上、中、下各部位烟叶感官质量下降。结合当地的生产实际综合分析，在5月1日前后移栽，烟叶产量较高，品质最优。
英文摘要：
To determine the best transplanting time and improve the quality of flue-cured tobacco in Shuangjiang county,Lincang city,the effects of different transplanting time（2 days around May 1,May 7, May 15） on tobacco growth,economic characters and quality were studied. The results showed that the to-bacco botanical characters,economic characters and leaves quality were decreased after topping with the transplanting time delayed. And it behaved dwarf plant,smaller average leaf areas,decreased 1st-class to-bacco proportion and average price. The change of the comprehensive evaluation index of chemical compo-nents was not obvious,and sensory quality of upper,middle and lower leaves were reduced. According to the practical production practice,high yield and good quality of tobacco were got when transplanting time was about May 1 .
