[Objective]The research aimed to study the effects of different amount of molybdenum on chemical composition and economic character of flue-cured tobacco. [Method] Wide field Comparative experiment with Yunyan 87 was carried out. [Result] Yield, output value and proportion of superior grade tobacco leaves were the highest at molybdenum application amount of 80 ml/plant. Molybdenum application a-mount of 80 ml/plant was benefit to improve the content of total sugar and reduce sugar content. Molybdenum application amount of 40 ml/ plant was benefit to improve potassium content,reduce total nitrogen, nicotine, chlorine content,consort sugar nicotine ratio, nitrogen base ratio and potassium chloride ratio of tobacco. [ Conclusion] The optimum molybdenum application amount was 40-80 ml/plant.%[目的]研究不同施钼量对烤烟化学成分含量和经济性状的影响.[方法]采用大区对比试验,对云烟87进行不同施钼量处理.[结果]施钼量80ml/株烟叶产量、产值、上等烟比例最高,且有利于提高烟叶总糖、还原糖含量；施钼量40ml/株有利于提高烟叶钾含量,降低烟叶总氮、烟碱、氯含量,并协调烟叶糖碱比、氮碱比和钾氯比.[结论]施钼量宜选择40～80ml/株.
