摘　　要：通过对比45d、55d、60d、65d、75d5种不同苗龄的漂浮苗移栽到大田后烟株的生物学性状、根系生理活性指标和产质量等差异，结果表明：苗龄为55-65d的烟苗移栽后，烟株的根系生长、根系活力，田间长相长势及最终产量质量最好。By comparing the differences of biological characteristics of tobacco plant, physiological active indicators of root system, yield and quality of five kinds of floating seedlings transplanted at 45 days, 55 days, 60 days, 65 days and 75 days, the results showed that the root system growth and activity, tobacco plant growth, yield and quality of those transplanted between 55 days and 65 days are the best.
