In order to clarify the influences of transplanting date on the yield and quality of flue — cured tobacco, the experiment on the seeding and transplanting date was conducted in Jianyang, Fujian province. The results showed that: along with the deferring of seeding and transplanting date, tobacco growth was quickened, tobacco growth duration was shortened, and the biomass was decreased. There were better economic characters of flue - cured tobacco leaves and better smoking quality of lower and middle leaves when transplanting date was on 8th, February; but upper leaves got better smoking quality when transplanting date was on 19th, January. Therefore, the optimum seeding date of CB - 1 was from 19th, October to 8th, November, and the optimum transplanting date was from 19th, January to 8th, February in the following year.%为了明确播栽期对烤烟产量和质量的影响,在福建建阳开展了烤烟播栽期试验,结果表明:随播栽期的推迟,烟株生育期明显缩短,生物量积累减少；2月8日移栽处理的烤后烟叶经济性状和中、下部叶评吸质量表现较好,而上部叶评吸质量以1月19日移栽处理较好,因此烤烟翠碧1号在福建建阳的最佳播种时间是当年10月下旬～11月上旬,移栽时间是次年1月下旬～2月上旬.
