| 摘 要： | 对盐碱土的两种提取液的阴、阳离子的测定值，应用推理计算法，揭示了饱和提取液到５：１提取液之间发生的一系列定量的化学过程和物理化学过程。对这批土样，即ＣａＣＯ３、ＣａＳＯ４、ＭｇＣＯ３的溶解；溶液中的Ｃａ＋Ｍｇ与胶体上的交换性Ｎａ之间的交换反应；还有负吸附效应。

| Abstract: | Measurement values of negative and positive ions from the two extract-ing solutions for the saline-alkali soil,by means of deductive calculation,reviewed a se-ries of quantitative chemical and physi-chemical processes occurred in the solutionranging from saturated extracting solution to a 5:1 diluted solution.The sample soil issolvent CaCO3,CaSO4 and MgCO3. In the solution Ca+Mg cause exchangeable reac-tions with colloidal exchangeable Na. |
