摘要
对2006年湘西2大主产烟区(桑植烟区和龙山烟区)202个烤烟样本的5种常规化学成分进行了分析与评价,并与云南烤烟的常规化学成分进行了对比分析.结果表明:2大主产烟区烤烟总糖含量略高于优质烟叶范围,但均低于云南烟叶总糖含量;烟碱含量大多在适宜水平偏高区域,且大都高于云南烟叶烟碱水平;氯和总氮含量多在优质烟叶化学含量指标范围内,糖碱比和钾氯比大小基本适宜,但糖碱比大都低于云南烟叶糖碱比;氮碱比值低于优质烤烟含量范围.说明要进一步提高湘西地区烟叶的化学品质,需改善生态及栽培条件,运用复烤调制技术,降低总糖及烟碱含量,提高含钾水平.
Five conventional constituents in 202 flue-cured tobacco samples from two tobacco areas(Longshan and Sangzhi) of Xiangxi in 2006 were analyzed and evaluated.By the comparison with that from Yunnan,it was found that the content of total sugar in Xiangxi tobacco was higher than the sugar range of good quality tobacco,but lower than that in Yunnan tobacco.For most tobacco samples in Xiangxi,the content of nicotine was in a suitable but slightly high level and higher than that from Yunnan.The content of Cl-1 an...
