摘要
以临沧烟区烤烟样品为材料,研究了上部叶的采收方式(分次采收和一次性采收)对烟叶物理性状、化学成分和经济性状的影响。结果显示,一次性采收方式收获的顶部1～3片叶的单叶重、叶质重高于分次采收处理,而采用两种采收方式收获的顶部1～3片叶的拉力、填充值、含梗率间的差异不显著,一次采收方式收获的顶部4～6片叶的单叶重、叶质重、叶片厚度、拉力低于分次采收;一次性采收的烟叶总糖和还原糖含量提高,烟碱、总氮和氯含量降低,烤后烟叶的化学成分较协调,评吸质量较好,但产量和产值有所下降。
Flue-cured tobacco samples from Lincang tobacco growing area was used to investigate the effects of harvesting methods（upper leaves harvest completed by two primings at regular interval and by one priming） on physical character,chemical composition and economic character of the upper leaf.The results showed that single leaf weight and weight per leaf area of the top 1st-3rd leaves by one-priming were higher than those by two-priming.No significant difference was observed in the tensile strength,filling value and stem content of the top 1st-3rd leaves between the two methods.The single leaf weight,weight per leaf area,leaf thickness,tensile strength of the top 4th-6th leaves by one-priming were lower than those by two-priming.Comparing with two-priming,the leaves harvested by one-priming contained more total sugar and reducing sugar,but less nicotine,total nitrogen and Cl,the chemical composition in cured leaves was more harmonious,offered better smoking quality,but slightly lower yield and output value.
