Preliminary Study on the Effects of Transplanting Date on the Growth and Yield and Quality of Flue-cured Tobacco

结果表明，泌阳县烤烟在４月底至５月上旬移栽，烟株大田长势旺盛，叶多株高，叶片扩展好，身份厚薄适中，产量、上等烟比例、均价及产值较高。推迟或提前移栽，烟叶的产量、上等烟比例、均价及产值均下降，尤以推迟移栽下降幅度较大。

A study was carried out on the effects of transplanting date on the growth,yield and quality of flue cured tobacco.
