不同揭膜时期对福建省南平烟区烟叶品质的影响

目的]探索适宜福建省南平烟区烟叶生长的揭膜时期。方法]采用田间试验研究了不同揭膜时期对南平烟叶农艺性状、经济性状、化学成分的影响,并对烟气质量进行了评吸鉴定。结果]以移栽后40 d揭摸更能促进烟株生长,有利于干物质积累,经济效益也较好;化学成分分析表明,移栽后40 d揭膜烟碱含量有所下降,协调性较好;感官评吸结果表明,移栽后40 d揭膜烤后烟叶较其他处理好。结论]以移栽后40 d揭摸对保障南平烟区烟叶品质较为适宜。

Effects of Durations of Disclosing Plastic Film on th e Quality of Flue-uc red Tobac co in NanpingTo bacco Area

Abstar ct Objective] To research the duration of disclosing plastic film during the tobacco leaf growth in Nanping Tobacco Area in Fujian Prov-ince.Method] Field experiment was conducted to investigate the effects of the duration of disclosing plastic film on the chemical components, economic characters and agronomic characters of flue-cured tobacco.Smoke quality was identified . Result] Uncovering film at the time of 40 days after transplanting could promote the growth of plants, was helpful to the accumulation of dry matter, and increased the economic benefits. Chemical composition analysis indicated that the coordination of chemical composition was better after he plants were transplanted for 40 d and the content of nicotine decreased.Sensory evaluation results also suggested that it was better to uncover the plastic film at 40 d after transplanting. Conclusion] It is proper to uncover the plastic film after transplanting for 40 d in Nanping Tobacco Area.
