摘　　要：通过大田对比试验,研究了打顶后喷施不同浓度的叶面活性物质"烟博士"对烤烟上部叶的影响。结果表明,喷施一定浓度的"烟博士"会明显促进烤烟上部叶叶长、叶宽、叶面积的增加,并降低上部叶烟碱含量,使化学成分更加协调,产值和中上等烟比例增加。以喷施"烟博士"1000倍稀释液的效果最好。The effects of spraying different concentrations of active substance ＂cigarette doctor＂ on leaves after topping on the upper leaves of flue-cured tobacco were studied through comparative tests conducted in the field.The results indicated that spraying a certain concentration of ＂cigarette doctor＂ could markedly promote the increase of length,width and area of upper leaves,decrease the nicotine content in the upper leaves,make the chemical compositions in the upper leaves more coordinative,and enhance the output value and the proportion of medium and first -class leaves. Among different concentration treatments, spraying the 1000 times diluent of ＂cigarette doctor＂ had the best comprehensive effects.
