| 摘 要： | 目的]为了明确毕节地区各烟区的烟叶物理特性。方法]通过对2005年毕节地区8县(市)烟叶主要物理性状的测定,分析了不同地点、颜色和等次间烟叶物理性状的差异,并对不同地点间烟叶物理性状进行聚类分析,研究了烟叶物理性状间及其与海拔间的相关性。结果]毕节地区各区烟叶物理性状均在较适中范围,综合物理性状表现较好;不同县(市)烟叶的物理性状差异达到1%显著水平;桔色烟的物理性状表现均优于柠色烟;不同等次间除含梗率外其余物理性状差异显著;主要物理性状间显著相关,海拔与单位叶面积重显著正相关;对不同区域烟叶综合物理性状聚类分析,可将毕节地区划为3个类型烟区。结论]该研究为改进毕节地区的烟叶生产技术提供了理论依据。

| Abstract: | Objective] The research was constructed to confirm the physical characteristics of tobacco leaves in different regions of Bijie prefecture.Method] The differences in physical characteristics of tobacco leaves in various spots,colors and grades were analyzed by determining major physical characteristics of tobacco leaves in 8 counties(cities) of Bijie prefecture in 2005.The clustering analysis was conducted on physical characteristics of different sites and the correlations between physical characteristics of tobacco leaves and that with altitude were studied.Result] Physical characteristics of tobacco leaves in Bijie district were at the middle level and with better comprehensive characteristics.The differences among physical characteristics of different counties(cities) reached at 1% extremely significant level.Physical characteristics of orange tobacco leaves exhibited better than that of lemon leaves.Except stalk content,all physical characteristics had significant differences among different grades of tobacco leaves.There existed significant correlation among phisical characteristics and significantly positive correlation between the altitude and weight per unit leaf area.Bijie prefecture was divided into 3 types of tobacco regions according to the results of clustering analysis on comprehensive physical characteristics of tobacco-leaves in different regions.Conclusion] The research provided the scientific basis for improving the production technology of tobacco leaves in Bijie prefecture. |
