【摘要】 本文采用数理统计的方法,系统分析了烤烟中烟碱含量与总氮、总糖、钾的相关关系。研究表明:烤烟中烟碱含量存在明显的阈值;以烟碱阈值为界,烤烟中烟碱含量与总氮、总糖、钾的含量存在两种相反的相关关系,当烟碱含量大于阈值时,烟碱与总氮呈正相关关系,与总糖、钾呈负相关关系,当烟碱含量小于阈值时,烟碱与总氮呈负相关关系,与总糖、钾呈正相关关系。更多还原

【Abstract】 Correlations between nicotine content and total nitrogen,total sugar,K2O in flue-cured tobacco were studied in this article.The results were as follows.There was a threshold of nicotine content in flue-cured tobacco leaf.When nicotine content was higher than the threshold of nicotine content there were positive correlations between nicotine content and total nitrogen,negative correlations between nicotine content and total sugar,potassium;When nicotine content was lower than the threshold of nicotine content there were negative correlations between nicotine content and total nitrogen,positive correlations between nicotine content and total sugar,potassium.更多还原
