“烟博士”活性制剂对烤烟上部烟叶生长及其品质的影响

Effects of "Yanboshi" active agent on growth and smoking quality of the upper leaves of flue-cured tabacco

通过大田对比试验,研究了"烟博士"活性制剂对烤烟上部叶片生长及品质的影响.结果表明,喷施一定量的"烟博士"活性制剂明显促进烤烟上部叶叶长、叶宽.使叶面积增加,以15 g"烟博士"活性制剂兑水14 kg,于打顶期间隔7 d喷施2次效果最好.喷施"烟博士"活性制剂后上部叶烟碱含量降低,钾含量增加;化学成分更协调,烟叶评吸质量得到了提高.

Field experiment was conducted to study the effects of ＂Yanboshi＂ （YBS） active agents on the growth and smoking quality of the upper tobacco leaves. The result showed that spraying ＂Yan- boshi＂ could significantly increase the length,the width and the area of leaves. The treatment had the best effect when spraying 15 g ＂Yanboshi＂ active agents, adding water 14 kg and re-spraying on the 7th day. After spraying ＂Yanboshi＂ active agents, the upper leaves nicotine content was reduced, K content was increased; the chemical composition of tobacco content was more coordinated, and the smoking quality was increased.
