上部烟叶不同成熟度及采收方式对烤烟烘烤质量的影响

Effects of Maturity and Harvest Mode of Upper Leaves on Baking Quality of Flue-cured Tobacco

为进一步提高烤烟上部烟叶质量和工业可用性,研究了不同成熟度和采收方式对烤烟上部烟叶外观质量、主要化学成分及协调性、经济性状的影响。结果表明,T3处理对于改善上部烟叶外观质量、化学成分协调性、经济性状的效果较为突出,其烤后烟叶成熟度较好,油分多,色度强;淀粉和色素等大分子物质降解较为充分,总糖、还原糖、石油醚提取物含量较高;中上等烟比例高,均价和产值较对照分别增加了2.44元/kg、5325.60元/hm2。

In order to further improve the quality and industrial availability of upper leaves in flue -cured tobacco, the paper studied the effects of different maturities and harvest modes of upper tobacco leaves on their appearance quality , main chemical com-ponents and compatibility, and economic characters.The results showed that T 3 treatment could significantly improve the appearance quality, chemical components compatibility , and economic characters of upper leaves .Through T3 treatment, the baked tobacco leaves had better maturity, more oil content, and stronger chroma;macromolecular materials such as starch and pigment were more sufficiently degraded, and the contents of total sugar, reducing sugar and petroleum ether extract were higher;the proportion of mid-dle-class and superior tobacco leaves was higher;in comparison with the control, the average price and output value were increased by 2.44 yuan/kg, 5325.60 yuan/hm 2 , respectively.
