河南烤烟主产区烟叶物理特性的差异性分析

摘要

通过对河南烟叶4个主产区(许昌市、漯河市、商丘市、平顶山市)9个县区内的380个样品(C3F、B2F各190个)作了各项物理特性指标的测定,并进行统计分析,以确定河南主产区烟叶在物理特性上存在的差异和相似性.结果表明,不同烟区的烟叶物理特性存在不同程度的差异,河南主产区烟叶厚度和叶面密度总体偏高,含梗率适中,抗张力适宜,许昌市和漯河市的烟叶填充值较为适宜,平顶山市和商丘市的烟叶填充值较高,许昌市、漯河市、商丘市3个烟区之间烟叶的含水率较为接近.%The physical characteristics of 380 samples (C3F,B2F 190,respectively) in nine counties of Henan tobacco leaf (four main producing areas of Xuchang city,Luohe city,Shangqiu city and Pingdingshan city) were measured. Statistical anal-ysis was conducted to determine the differences and similarities in the physical properties of tobacco leaves in the main pro-ducing areas of Henan. The results showed that the physical characteristics of tobacco leaves in different tobacco areas were different,and the leaf thickness and leaf density of the main producing areas in Henan were higher than those in the main areas. The filling value of Xuchang and Luohe was suitable,Pingdingshan and Shangqiu tobacco filling value is higher, Xuchang,Luohe,Shangqiu tobacco between the three tobacco areas are relatively close.
