摘　　要：为提升丽江烟叶成熟度与品质,开展不同起垄高度和移栽时间双因素试验,分析烟株的生长指标、生理指标和碳氮转化过程,揭示起垄高度与移栽时间对丽江烟烤烟大田生长、烟叶成熟进程及烟叶成熟度的影响。结果表明,在丽江烟区气候环境下,垄高35 cm处理烟株碳氮转化时间早于垄高25 cm处理,有利于烟叶生长、成熟。5月10日移栽田间长势、干物质积累量、产量高于4月30日移栽。垄高35 cm、5月10日移栽组合(T4处理)均价和产值最高,中、上部烟叶成熟度提升,烟叶外观品质最好。In order to improve the maturity and quality of Lijiang tobacco leaves,double factor experiment of different ridge height and transplanting time was carried out.The growth index,physiological index and carbon and nitrogen transformation process of tobacco plant were analyzed,so as to reveal the effects of ridge height and transplanting time on field growth,leaf maturity and maturity of flue-cured tobacco in Lijiang.The results showed that in the climate environment of Lijiang,the C/N transformation time of tobacco plants treated with ridge height 35 cm was earlier than that of tobacco plants treated with ridge height 25 cm,which was conducive to the growth and maturity of tobacco leaves.The field growth,dry matter accumulation and yield of transplanting on May 10 were higher than those of transplanting on April 30.The T4 treatment had the highest average price and output value,the maturity of middle and upper tobacco leaves increased,and the appearance quality of tobacco leaves was the best.
