结果表明，从上挂开始到烟叶完全变红初期，烟叶外观特征变化最明显；在不同调制时期烟叶蛋白质与还原糖、总糖的含量呈负相关；热风循环干燥法和远红外线干燥法均可缩短调制时间，减少用工量，且烟叶化学成分保持相对稳定。

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。

The status of carbon metabolism and the harmony with nitrogen metabolism in Flue-cure tobacco correlate to the content of carbohydrate and nitrogenous compounds in Flue-cure tobacco leaf, therefore influencing greatly the production and quality of tobacco leaf.

烟株的碳氮代谢的强弱和协调状况与烟叶的碳水化合物含量及含氮化合物含量关系密切，从而对烟叶产量和品质产生重大影响。

The system is based on geographic information, ecology and tobacco leaf quality, flue-cured tobacco production and infrastructure management, three-dimensional visualization, WEB information composed of 5 sub-systems, with the objective of tobacco-growing areas of Qujing weather, soil, geomorphological features, tobacco production, infrastructure and basic tobacco-related information management, query and spatial statistics to show the application of tobacco-depth analysis of the topic, the establishment of expert decision support system,"the number of tobacco."

In the tobacco production, the measure of only using fertilizers in soil can notimprove the quality of tobacco because soil nutrients releasing is not coincident withthe nutrients absorb rules of tobacco, and the leaf fertilizer with low cost and higheffect can harmonize the nutrients of tobacco leaf and improve the economic benefitof tobacco under assorting with soil fertilizer.

烤烟生产中，由于土壤养分释放状况与烤烟吸肥规律并不一致，单一的土壤施肥并不能达到改善烟叶品质的目的，而成本低、肥效快的叶面肥可以针对烤烟不同生长发育期各异的养分需求特点，配合土壤施肥，协调烟叶自身营养状况，改善烟叶内在品质，进而提高烤烟经济效益。
