【摘要】In order to evade effectively adverse weather conditions in the actual production of flue-cured tobacco, such as low temperature stress in the early phase and heat forced maturity in the later, the field experiment was conducted to study the effects of different transplanting period and cold-resistant agent on tobacco growth and yield. The result showed that the tobacco leaf number was much more, and the leaf area was moderate when transplanting seedling under plastic film mulching 5 days in advance, while the leaf number was slightly less, the leaf area was the largest when transplanting under the plastic film mulching 10 days in advance.Spraying cold-resistant agent alone could cause slender leaves. It was pro-pitious to enhance the proportion of better-than -average tobacco and the yield when transplanting earlier.and spraying cold-resistant agent.%为有效规避烤烟生产中前期低温胁迫、后期高温逼熟的不利气候条件，在大田条件下，开展了不同移栽期及抗寒剂使用对烤烟生长发育和产量及其构成的影响。结果表明，提前5d膜下移栽，烟株叶片数较多，叶面积适中；提前10 d膜下移栽，烟株叶片数略少，但叶面积最大；单独使用抗寒剂会出现叶片细长现象，而配合提前膜下移栽，更有利于烤烟上中等烟比例和产量的提高。
