摘要
试验表明,在烟叶成熟的过程中,用茎叶夹角的大小能定量地反映烟叶的成熟程度。对品种K326下部叶片,当烟叶的颜色由绿转黄,茎叶夹角达60～70°,表明烟叶已经成熟,此时采收可获得最佳产量和质量;而对K326中、上部叶片,当烟叶的外观颜色达到一定程度,茎叶夹角达80～90°时,可视为适熟的标志,此时采收烟叶易于烘烤,烤后烟叶物理性状适宜,综合化学成分较协调。
The results indicated that the angles between leaf and stem could exactly reflect the ripeness of flue-cured tobacco leaves. The quality and yield was optimal at the harvest time when the colour turned green to yellow and the angles arrived 60-70° for cuhivar K326′s lower leaves. But for cutters and upper leaves, physical characteristics was appropriate and comprehensive chemical component was relatively harmonized when the colour reached specific degree and the angles arrived 80-90°.
