摘要
烟叶品质与生产环境的关系是烟叶标准化生产首要考虑的问题之一,为探明烤烟主要化学成分与土壤养分间的关系,对湖南主产烟区62份烤烟样品主要化学成分与对应的土壤样品养分进行了数理统计分析。结果表明:烤烟品种G80总糖、还原糖、钾含量显著高于其他3个品种;烟碱与总氮含量在品种间差异不显著。湖南烟区烤烟化学成分含量适中,糖含量以衡阳最高,张家界最低;烟碱含量以怀化最高,邵阳最低;总氮含量以永州最高,邵阳最低;钾含量以长沙最高,张家界最低;土壤有机质含量丰富,全氮和碱解氮含量处于中等水平,全磷含量偏低,有效磷含量处于中等水平,全钾与速效钾含量处于较低水平。土壤全磷和全氮含量对各烤烟化学成分的影响均较强。湖南省在烤烟标准体系的制定过程中要注意运用已有的定量认识,并综合运用经济因素,制定科学、成本节约的标准。可以按区域的不同制定相应的烟叶内控和工商交接质量标准,特别是在制定种植技术规程时要充分考虑当地环境状况。
The relationship between tobacco quality and the plant environment is one of the key questions in tobacco standardization production. In order to clarify the relationship of the major chemical composition in flue-cured tobacco leaf and soil nutrient, the major chemical composition of 62 tobacco samples and nutrient of the soil samples were analyzed by statistics analysis. The results indicated that the contents of total sugar, reducing sugar and potassium in GSO were higher than the other tobacco varieties significantly; the contents of nicotine and total nitrogen were no significant difference among tobacco varieties. The contents of flue-cured tobacco chemical composition were moderate in tobacco-growing area of Hunan. The contents of sugar were highest in Hengyang, lowest in Zhangjiajie. The content of nicotine was highest in Huaihua, lowest in Shaoyang. The total nitrogen was highest in Yongzhou, lowest in Shaoyang. The content of potassium was highest in Changsha, lowest in Zhangjiajie. The content of soil organic matter was richer. The contents of total nitrogen and alkalined-nitrogen were in the medium level. The content of total phosphorus was lower and the phosphorus available was in the medium. The contents of total potassium and quick-acting potassium were in the lower level. The effects of total phosphorus and nitrogen content in soil on flue-cured tobacco＇s chemical composition were stronger. We could pay attention to establish the standard for internal quality control and change for industry and commerce with the tobacco vary from the production base, especially, planting standard should consider its planting environment plenty. We could establish scientific and economical flue-cured tobacco standard system combined by existing technology quantitatively and economic factors comprehensively.
