伏旱烟叶采收成熟度研究

Study on Harvesting Maturity of Flue-Cured Tobacco

为了探索伏旱的烟叶合适的采收成熟度,设置了中部鲜烟叶50%、60%、70%、80%四个不同成熟度的处理。通过烤后烟叶等级质量、化学成分、评吸质量测定,结果表明,高温伏旱采收成熟度达70%,即叶尖黄5~7 cm,靠叶尖部叶缘黄2~3 cm,勾尖明显的,烤后烟叶内在质量最佳;伏旱烟叶采收成熟度达80%,即叶尖黄8~10 cm,靠叶尖部叶缘黄3~4 cm,勾尖明显,叶尖泛白或略有干枯的,烤后烟叶等级质量最佳。兼顾外观和内在质量,则以鲜烟叶成熟度在70%~80%时采收较为适宜。

In order to explore the appropriate harvest maturity of tobacco leaves in summer drought, four different maturity treatments of 50%, 60%, 70% and 80% of fresh tobacco leaves in central China were set up. The results showed that the leaf tip was 5~7 cm yellow and the leaf edge was 2~3 cm yellow at high temperature and drought, and the internal quality of cured tobacco leaf was the best. When the harvest maturity reaches 80%, that is, the leaf tip is yellow 8~10 cm, the leaf edge is yellow 3~4 cm, the hook tip is obvious, the leaf tip is white or slightly dry, and the grade quality of tobacco leaves after baking is the best. Considering the appearance and internal quality, it is more suitable to harvest fresh tobacco leaves with maturity of 70%~80%.
