摘要
采用相关以及多元线性回归分析法,对植烟土壤中的有机氮、碱解氮、铵态氮、硝态氮等氮形态与烟叶化学成分及评吸质量的关系进行研究,结果表明:对烟叶化学成分及评吸质量作用最为显著、贡献率最高的是有机氮,其次是碱解氮,再次是铵态氮和硝态氮。
Correlation analysis and multiple linear regression were performed to find the relationship between organic nitrogen, alkali dispelled nitrogen, ammonium nitrogen and nitrate nitrogen of soils and tobacco compositions, smoking quality. The results indicated that organic nitrogen had the highest contribution ; alkali dispelled nitrogen had the second highest contribution and nitrate nitrogen had the lowest contribution.
