摘要:通过优化现有的烤烟散叶插签烘烤工艺,探讨其对烟叶烘烤用时、耗能、外观质量及烤后经济性状的影响。结果表明,采用优化的干旱烟叶散叶插签烘烤工艺,其烟叶烘烤用时延长,烘烤耗能略有上升,但烤后烟叶以橘黄色为主、色度强、油分多、身份中等、组织疏松、中上等烟叶比例明显上升。总的来说,优化后的散叶插签烘烤工艺大大提高了干旱烟叶的烘烤质量。

Abstract: The tobacco flue-curing time, energy consumption, appearance quality and cured tobacco leaf economic traits were evaluated by optimizing the flue-curing technique of dry loose leaves of flue-cured tobacco inserting bamboo sticks. The results showed that the optimal curing technique of dry loose leaves of flue-cured tobacco inserting bamboo sticks extended the flue-curing time and increased flue-curing energy consumption slightly. Most of the cured leaf were orange with strong chroma, more oil, medium identity, loose tissue. The proportion of fine tobacco was significantly increased. The optimized technique of dry loose leaves of flue-cured tobacco inserting bamboo sticks can greatly improves the quality of tobacco curing.

烤烟是一种既喜水又怕涝的作物[1],干旱的情况下,烟叶水分含量较少、结构较紧密、内含物分布不均匀、干物质积累较充实[2]。提高干旱烟叶的烘烤质量和烤后烟叶化学成分的协调性,对于今后现代烟草农业的发展意义重大。
目前,国内干旱烟叶的研究多集中在栽培生理方面[3-6],其调制工艺的研究还有待深入。散叶插签烘烤工艺[7]能够较好地解决干旱烟叶在其烘烤上变黄难、失水难的问题。近年来,我国云、贵、川、渝等地旱情严重,广大烟区对干旱烟叶的烘烤工艺需求增加,因此本研究对干旱烟叶散叶插签烘烤工艺进行了研究。
1 材料与方法
1.1 试验材料
供试烟叶为云烟97,移栽期相同,除灌溉外,其田间管理按照优质烤烟栽培生产技术规范进行。……
