摘要
采用相关以及多元线性回归分析法,对植烟土壤中的全钾、速效钾、缓效钾与烟叶化学成分及评吸质量的关系进行研究,对烟叶化学成分及评吸质量作用最为显著、贡献率最高的是缓效钾,其次是速效钾,再次是全钾。其中,土壤缓效钾与有机酸、总糖、多酚、施木克值、总还原糖、评吸总分、香气量、余叶等烟叶化学成分及评吸质量呈极显著或显著正相关。
Correlation analysis and multiple linear regression were performed to find the relationship between total potassium,quick-acting potassium and slow-acting potassium in soil and tobacco compositions and smoking quality.The results indicated that slow-acting potassium had the highest contribution to tobacco compositions and smoking quality, followed by quick-acting potassium and total potassium Positive. Correlations between slow-acting potassium and chemical components tobacco leaf such as organic acids,total sugar,polyphenol, the ratio of carbon and nicotine, total reducing sugar, and smokinging qualities such as smoking total scores, regression model of aroma, concentration of aroma, F the aftertaste were found.
