When RN was 25%∶75%,N and amylum were lowest,and volatile base were highest.With 100% ammonium,reducing sugar,Cl and amylum were highest,and K/Cl,nicotin and K were lowest.With 100% nitrate,the content and uptake of N,K and Cl were the lowest;3 Any RN,the content of nicotin,N,K,Cl and amylum satisfied the demand of high quality tobacco,reducing sugar was on the other way round.

RN为25%∶75%时，挥发碱含量最高，总氮、淀粉含量最低。100%铵态氮时，还原糖、氯含量、淀粉的含量最高，碱、钾、钾氯比最低，同时显著地降低烤烟的等级结构。100%硝态氮时，总氮、钾、氯在烟叶中的含量最低，吸收总量也最少，同时产量、产值、均价也处于最低水平；3本试验的任何RN下，烟碱、总氮、钾、氯、淀粉的含量均符合优质烟叶要求，而还原糖相反。

The analysis of correlation indicated that tobacco breeding with higher potassium content has the characteristics of higher stalk height, wider stalk circumference, longer leaf and more leaf number comparatively. The correlations between potassium content and nicotin among top, middle and bottom tobacco leaves were all negative. The correlation among potassium content and malondialdehyde,superoxide dismutase, conductance ratio; and protein, solubility sugar, chlorophyl and free water/bondage water were all attained marked level, however, the essence of correlation was different: the former was negative but the latter was positive. 4.The analysis of heterosis demonstrated there were different degree heterosis in the potassium content of tobacco leaf and other correlated characters, including agriculture, physiology and biochemistry.

相关分析表明，烟叶钾含量性状与株高、茎围和最大叶长的相关性达到了显著和极显著的水平，与叶数的相关虽未达到显著水平，但相关程度相对较高；烟叶钾含量与烟碱在上、中、下三部位叶之间均呈负相关关系，中部叶烟碱与烟叶钾含量的相关达到了极显著水平；烟叶钾含量性状与丙二醛、SOD和电导率以及与蛋白质、可溶性糖、叶绿素和自由水/束缚水之间的相关性均未达显著水平，但相关性质不同，烟叶钾含量性状与前三者之间表现负相关关系，而与后四者之间呈正相关关系；4。

The results showed: 1 RN didn't the leaf width,leaf long,leaf area,yield,productive value and average price of flue-cured tobacco,but had significant effect on grad composing,content of chemical component and the accumulation of N,K and Cl.Within limited rang of RN,the relations between yield,average price,yield of high grad tobacco,yield of low grad tobacco,nicotin,N,reducing sugar,Cl,amylum,volatile base and the quotient of ammonium would been described by significant quadratic polynomial,and the relations between K and the quotient of ammonium conformed to negative linear equation;2With a RN of 75%∶25%,the value of proportion of high and middle grad tobacco,content of nicotin,N,K,uptake of N and K/Cl were the highest,volatile base was lowest.

结果表明：1RN对烤烟的农艺性状、产量、产值、均价等没有明显影响，而对烤烟的等级结构、内在化学成分含量、氮、钾、氯的吸收量有着显著影响，可以用显著的二次多项式模型或直线相关方程描述产值、均价、上等烟产量、下等烟产量等经济性状以及烟碱、总氮、钾、还原糖、氯、淀粉、挥发碱等内在化学成分的含量与铵态氮份额之间的关系；2RN为75%∶25%时，中上等烟比例、烟碱、总氮、钾、钾氯比、氮吸收量最高，挥发碱含量最低。
