摘 要：为探索不同移栽期对烤烟品种云烟87产量和品质的影响，在皖南鄂皖、沪皖2个试验点开展了不同移栽时期试验。结果表明，在鄂皖试点，不同移栽期对云烟87的农艺性状、经济性状及烤后烟叶质量影响均不大;在沪皖试点，移栽期比当前生产推迟后，叶片数增多，茎围和节距减小，烤后烟叶上等烟比例降低，外观质量变差。综合2个试验点来看，云烟87在皖南3月19日左右（皖南当前生产移栽期）进行移栽，综合性状表现较好。

Abstract： In order to explore the effects of different transplanting time on the yield and quality of flue-cured tobacco variety Yunyan 87， experimental studies at different transplanting time were carried out in two experimental sites in Ewan and Huwan of southern Anhui. According to the experimental results of Ewan Demonstration Park， different transplanting periods had little effect on the agronomic and economic traits of Yunyan 87 and the quality of tobacco leaves after curing. From the test results of Huwan Demonstration Park， the number of leaves increased， the stem circumference and pitch decreased， the proportion of high-quality tobacco leaves decreased and the appearance quality became worse after the delay of transplanting period compared with the current production. On the whole， Yunyan 87 was transplanted in the current transplanting time （around March 19） in southern Anhui Province， and its comprehensive characters showed good performance.

移栽期是优质烟叶生产的关键因素之一，同一区域同一品种，不同移栽期的温度、光照、降水等气象条件不同时，烟草的生长发育及品质均会受到影响[1-5]。皖南烟区是安徽烟叶生产主产区，当前主栽的烤烟品种主要为云烟97，种植品种比较单一、结构性矛盾突出，急需对烤烟生产品种进行优化升级。近几年来，通过烤烟新品种（系）的生产示范对比试验，初步筛选出云烟87、中川208等综合性状较好的几个品种，拟提供皖南生产进一步研究利用[6]。其中，云烟87在云烟97之前曾在皖南推广种植，该品种抗黑胫病、中抗青枯病、综合经济性状较好，化学成分协调性较好，适应性广，抗逆力强，是一个好栽易烤的品种[7]。近两年在皖南恢复性种植试验表明，云烟87在病毒病低发区种植，综合性状仍然表现较好。因此，为探索云烟87在当前皖南……
