为了明确气候因子与烤烟品质之间的关系,对卢氏县2005~2012年度气象数据与当地烤烟常规化学成分含量数据进行了相关性分析。结果表明:平均气温与中部叶氯元素累积、中部叶钾氯比、下部叶糖碱比显著相关;空气相对湿度与上部叶钾元素累积显著相关,降雨量与上部叶钾、氯元素的累积和中部叶还原糖含量显著相关。在今后的烟叶生产中,可有针对性地调整烤烟的播种时间或是采取其他管理措施,来平衡烟叶中的化学成分含量,提高烟叶品质。
In order to clarify the relationship between climatic factors and the quality of flue-cured tobacco, the correlation analysis was made between the ROC data of 2005 ~ 2012 and the conventional chemical composition of local tobacco. The results showed that the mean air temperature was significantly correlated with the accumulation of chlorophyll in the middle part, the ratio of potassium to chloride in the middle part and the proportion of the lower part of leaf in the middle part. The relative humidity of air was significantly correlated with the accumulation of potassium in the upper part. Central leaf reducing sugar content was significantly correlated. In the future of tobacco production, tobacco planting can be targeted to adjust or take other management measures to balance the chemical composition of tobacco leaves, improve tobacco quality.
