摘要 通过田间试验，研究了长春柳河烤烟上部叶不同采收方式对烤后烟叶质量的影响。结果表明，与常规分批采收相比，上部6片叶一次性采收方式下，烟叶产量略有下降，但外观质量、评吸质量、上等烟比例、均价显著提高，化学成分更加协调，烟叶产值效益略有增加。

Abstract The effects of different harvesting methods on the quality of flue-cured tobacco were investigated in the field experiment. Results showed that one time harvesting way was better than divided harvesting way， which could improve tobacco appearance quality， smoking quality， percentage of superior leaves， average price and chemical elements. By using one time harvesting， tobacco yield decreased slightly，but the output value enhanced slightly.
