摘　　要：通过田间试验,研究了于烤烟打顶当天进行钼、锌单独及混合叶面喷施对烤烟上部叶开片、内在化学成分和中性致香物质含量的影响。结果表明,叶面喷施钼或锌能有效促进上部叶的生长,叶面积显著高于清水对照;叶面喷施钼或锌能显著提高烤后上部叶的叶长、叶宽、叶质重、填充值和抗张力,降低含梗率;叶面喷施钼或锌不同程度地提高上部叶两糖、总氮和钾含量,增大糖碱比、钾氯比,降低烟叶烟碱和氯含量,有效改善烟叶化学成分的协调性;喷施钼或锌可显著增加上部叶中性致香物质总量、各类致香物质含量;钼和锌混合喷施的上部叶叶面积、化学成分协调性和中性致香物质总量均高于钼或锌的单独施用,对烤烟上部叶开片、物理性状、内在品质的改善作用效果最佳。A field experiment was conducted to study the effect of Mo or Zn alone and mixed foliar sprayingon the leaf opening,internal chemicalcomposition and neutral aroma content of upper leaves in flue-cured tobacco. The results showed that spraying of Mo or Zn could promote the growth ofthe upper leaves and the leaf area was significantly higher than that of the control.Spraying Mo or Zn could significantly improve the leaf length,leafwidth,leaf weight,filling value and anti-tension of the upper leaves after baking. Spraying Mo or Zn could increase the content of total sugar,totalnitrogen and potassium in the upper leaves,increase the ratio of sugar to nicotine,potassium to chlorine,reduce the nicotine and chlorine content oftobacco leaves,and improve the coordination of chemical composition of tobacco leaves;Spraying Mo or Zn could significantly increase the total amountof neutral fragrant substances in the upper leaves and all kinds of fragrant substances;Mixed spraying of Mo or Zn was higher than the separate sprayingof Mo or Zn,and the effect of improving the quality of the upper leaves of flue-cured tobacco was the best.
