| 摘 要： | 对延边主要种烟地区的气候因子与烤烟叶片化学成分之间的关系进行了分析。结果表明:延边烟区中部烟叶中总糖和烟碱含量相对较高,总氮含量偏低;在烤烟大田期,气温适宜,降雨量季节性明显,日照充足,相对湿度变化幅度小;气候因子与烟叶化学成分间有显著或极显著的相关性,其中降雨量对烟叶化学成分的影响最大,日照时数和平均相对湿度的影响次之,平均气温的影响最小。

| Abstract: | The relationships between main climatic factors and chemical components of flue -cured tobacco leaves in major to-bacco-planting districts of Yanbian city were analyzed .The results showed that：in Yanbian area , the contents of total sugar and nicotine in middle-part tobacco leaves were relatively high , but the content of total nitrogen was slightly low .During the growth of flue-cured tobacco in field , the air temperature was suitable , the rainfall changed obviously and seasonally , the sunshine time was sufficient, and the relative humidity was less changed .There were significant or extremely significant correlations between climatic factors and chemical components of tobacco leaves .The rainfall had the greatest influence on the chemical components of tobacco leaves, followed by the sunshine duration and average relative humidity , while the average air temperature had the weakest influ-ence. |
