本试验通过H饱和树脂模拟根系吸钾过程，探索黄土性土壤非交换钾的释放动力学特征，并用暗棕壤和风砂土作参照，旨在为了解黄土性土壤非交换性钾释放动力学特征和评价供钾特性提供科学依据。

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 average level of the soil available potassium was 119.96 mg/kg, which decreased 18.94 mg/kg and 1.05 mg/kg one year averagely. But the decreasing trend alleviated in recent years. There were 39.5 kg/hm^2 nitrogen and 30.9 kg/hm^2 phosphorus (P2O5) more than needed averagely, and 150.0 kg/hm^2 potassium (K2O) in deficiency. Though the fertilizer application was high and the rate of fertilizer was 647.96 kg/hm^2 in nutrient, the ratio of organic to inorganic was still unreasonable. The ratio of the chemical fertilizer nitrogen phosphorus (P2O5) and potassium (K2O) was 1:0.42:0.14. The nitrogen application was enough and even higher than that was needed. The phosphorus was proper elementarily and potassium was in deficiency. The yield of wheat which was the main crop increased slightly and that of other autumn harvest crops was stable.

土壤速效钾7年平均值119.96 mg/kg，比第二次土壤普查时下降了18.94 mg/kg，平均每年以1.05 mg/kg的速度下降，但近年来下降趋势变缓；养分平衡中氮素平均盈余39.5 kg/hm^2，磷素(P2O5)盈余30.9 kg/hm^2，钾素(K2O)亏缺150.0 kg/hm2；全省施肥水平较高，每公顷总施肥量折纯养分647.96 kg，但有机无机比仍不合理，化肥氮、磷、钾投入比例1：0.42：0.17，氮肥充足，部分地区用量偏高，磷肥基本合理，钾肥不足；主要农作物小麦产量略有上升，其它主要秋收作物产量基本稳定。

A Potassium ion transfer and electron transfer between potassium ferricyanide in the aqueous phase and ferrocene in nitrobenzene are observed using potassium ferricyanide/potassium ferrocyanide as the redox couple. Meanwhile, the transfer reactions of some hydrophilic ions (Li〓, Na〓, H〓, K〓 and NH〓〓) are obtained using ferric sulfate/ferrous sulfate as the redox couple.
