摘要
为探究土壤微量元素与烟叶常规化学成分的关联程度,及为提高烟叶质量提供理论依据,运用描述统计、简单相关和典型相关统计分析方法,研究了湖南省桃源县烟区植烟土壤微量元素与烟叶常规化学成分的关系。结果表明,桃源县烟区土壤中铁、锰、锌、铜、硼和钼含量平均值均在适宜范围及以上水平;土壤有效铜含量与烟叶中钾含量呈极显著负相关;土壤有效硼含量与烟叶中还原糖、总糖、氯含量和糖碱比呈极显著正相关,与总氮、蛋白质含量和钾氯比呈极显著负相关;土壤有效钼含量与还原糖含量、总糖含量和糖碱比呈极显著负相关,与总氮和蛋白质含量呈极显著正相关;土壤微量元素含量对烟叶常规化学成分的影响为有效硼>有效钼>有效锰>有效锌>有效铁>有效铜。通过典型相关分析表明,随着桃源县土壤有效锰和有效硼含量的减少或者有效钼含量的增加,能够引起烤后烟叶烟碱、总氮、蛋白质含量和钾氯比的增加以及还原糖、总糖、氯含量和糖碱比的降低。
In order to explore the relationship between soil micronutrient and conventional chemical components of tobacco leaves, and to provide theoretical basis for stabilizing and improving the quality of tobacco leaves, descriptive statistics, simple correlation and typical correlation statistical analysis methods were used, and the relationship between soil micronutrient and chemical components of flue-cured tobacco leaves in Taoyuan county tobacco growing areas was studied. The results showed that the average contents of Fe, Mn, Zn, Cu, B and Mo in soil of tobacco-growing areas in Taoyuan county were all in the suitable range or above. Soil available Cu was negatively correlated with K of flue-cured tobacco leaves. Soil available B was positively correlated with reducing sugar, total sugar, chlorine, sugar to alkali ratio, and negatively correlated with total nitrogen, protein, potassium to chlorine ratio. Soil available Mo was negatively correlated with reducing sugar, total sugar, and sugar to alkai ratio, and positively correlated with total nitrogen, protein. The effect of soil micronutrient on the chemical composition of flue-cured tobacco were as follows: available B > available Mo > available Mn > available Zn > available Fe > available Cu. The results of canonical correlation analysis showed that nicotine, total nitrogen, protein, potassium to chlorine ratio increased with the decrease of available Mn and B or the increase of available Mo of soil in Taoyuan county, and decreased reducing sugar, total sugar, chlorine and sugar to alkali ratio.
