| 摘 要： | 为探索安康烟区烤烟物理性状年度间变化规律,对安康烟区2011－2016年不同部位的烤烟物理性状指标进行分析。结果表明,烟叶物理性状在年度间存在差异,下部叶2014-2015年含梗率有所上升,2016年下降；除2013和2016年外,中部叶含梗率较高；上部烟叶2011-2013年含梗率逐年下降,此后至2015年逐年升高,2016年再次下降。下部烟叶单叶重年度间变化不大,2016年中部烟叶单叶重显著升高,上部烟叶单叶重以2011和2016年最高。下部烟叶叶面密度逐年缓慢升高；中部烟叶叶面密度2011-2013年逐年升高,此后至2015年缓慢下降,2016再次升高；上部烟叶叶面密度2011-2012年逐年升高,此后至2015年逐年下降,2016年再次升高。下部烟叶开片度年度间变化不大,中部烟叶开片度2011-2014年总体表现出逐年下降的趋势,此后至2016年逐年快速升高；上部烟叶开片度2011-2014年逐年下降,2015年有所回升,2016年再次下降。中下部烟叶拉力在2011-2012年无明显变化,2013年有所下降,此后至2015年无明显变化,2016年迅速升高；上部烟叶拉力2011-2012年无明显变化,2013年下降,此后至2015年逐年上升,此后至2016年无明显变化。

Changes of physical properties of flue-cured tobacco of different years in Ankang tobacco growing area |

| Abstract: | To explore the change regularity of physical properties of flue-cured tobacco of different years from Ankang tobacco growing area, physical properties of different parts of flue-cured tobacco from 2011 to 2016 were analyzed. Results showed that there were differences in physical properties by years, stem ratio of lower leaves rose in 2014-2015 and declined in 2016. Stem ratio of middle leaves was high except in 2013 and 2016. Stem ratio of upper leaves declined from 2011 to 2013, and then rose year by year till 2015, and declined again in 2016. There were no significant changes in single leaf weight of lower leaves from 2011 to 2016, but single leaf weight of middle leaves significantly increased in 2016. Single leaf weight of upper leaves in 2011 and 2016 was higher than those in other years. Unit leaf area weight of lower leaves rose year by year, unit leaf area weight of middle leaves rose year by year from 2011 to 2013, and then declined slowly till 2015, and rose again in 2016. Unit leaf area weight of upper leaves rose from 2011 to 2012, and then declined year by year till 2015, and rose again in 2016. There were no significant changes in leaf width-length ratio of lower leaves from 2011 to 2016. Leaf width-length ratio of middle leaves declined year by year from 2011 to 2014, and then increased quickly till 2016. Leaf width-length ratio of upper leaves declined year by year from 2011 to 2014, and then increased in 2015, and declined again in 2016. There were no significant changes of leaf tensile strength of lower and middle leaves from 2011 to 2012, but declined in 2013 and then kept the same level till 2015, and rose sharply in 2016. There were no significant changes of leaf tensile strength of upper leaves from 2011 to 2012, but declined in 2013, and increased year by year till 2015, and then kept the same level till 2016. |
