摘　　要：采用盆栽试验研究缺钼烟田施钼对烟草光合作用和氮代谢及烟叶品质的影响。结果表明,施钼能明显提高烟草生育前期的光合速率和NR活性,促进烟草生育前期NO3--N的转化,提高烟叶钾含量和改善烟叶油分状况。The effects of molybdenum applying in tobacco field short of molybdenum on the photosynthesis, nitrogen metabolism and quality of tobacco were studied with pot experiment. The results showed that molybdenum applying could significantly enhance photosynthetic rate, NR activity and nitric nitrogen （ NO3- - N） conversion of tobacco during early growth stage, increase potassium content and improve oil status of tobacco leaf.
