| 摘 要： | 目的]研究不同品种、栽培土壤及海拔条件下的烤烟化学特性。方法]分析不同品种(K326、云烟87和G80)、栽培土壤(水稻田和旱地)和海拔(0～300、300～800和>800 m)对烤烟烟叶的总糖、还原糖、总氮、烟碱、钾、氯含量以及两糖差、糖碱比、氮碱比、钾氯比的影响,并对烟叶化学特性与海拔的相关性进行分析。结果]研究的3个品种烤烟化学特性存在一定差异,且K326和云烟87化学品质比G80好;水稻田和旱地2种植烟土壤种植的烤烟烟叶化学成分存在较大差异,其中水稻田烟叶总氮、钾和氯含量显著高于旱地;不同海拔种植的烤烟烟叶总糖、还原糖、烟碱、钾和氯含量有显著差异,总糖、还原糖含量以及氮碱比与海拔呈显著正相关,烟碱和氯含量与海拔呈显著负相关。结论]该研究可为制定湖南烟草种植区划、调整栽培技术以及卷烟工业选择原料提供参考。

| Abstract: | Objective] The aim was to study the chemical characteristics of tobacco under different varieties,cultivating soils and altitudes.Method] The contents of total sugar,reducing sugar,total nitrogen,nitrogen,potassium,chlorine,and the difference between total sugar and reducing sugar,sugar-nicotine ratio,nitrogen-nicotine ratio,potassium-chlorine ratio in tobacco leaves from different varieties(K326,Yunyan87 and G80),cultivating soils(paddy and dry land) and altitudes(0-300,300-800 and above 800 m),as well as correlation between altitude and chemical characteristics were researched.Result] The results indicated that there were some differences of chemical characteristics among three tobacco varieties,and K326 and yun87 were better than G80.There was a great difference of the chemical constituents of tobacco in paddy and dry land,and the contents of total nitrogen,potassium and chlorine of tobacco planting in paddy were higher than dry land.There was a great difference of total sugar,reducing sugar,nitrogen,potassium,chlorine content in tobacco planting in different altitude,and there was a significant positively correlation between the total sugar content,reducing sugar content,nitrogen-nicotine ratio and altitude,a significant negatively correlation between the nitrogen content,chlorine content and altitude.Conclusion] The study provides a reference for drawing up tobacco planting division,adjusting cultivation technology and choosing raw materials for cigarette industry of Hunan Province. |
