| 摘 要： | 本文旨在介绍一种检测土壤中交换性钙镁含量的简便方法。该简化方法采用电感耦合等离子体发射光谱仪(ICP-OES)作为检测手段,以乙酸铵为离子交换剂,用振荡提取的方法提取出土壤中的交换性钙、镁。结果显示：本方法测得的数据具有很高的准确度,因此该方法适用于各种土壤含量中交换性钙镁含量的测定。同时,本方法与已有的检测方法相比,试剂用量减少,步骤简化,更适合大批量检测。

| Abstract: | To introduce a conventional method to detect exchangeable Ca and Mg in soil, the inductively coupled plasma spectrometer( ICP-OES) was used as detection means, and ammonium acetate was used as ion-exchange extractant after the exchangeable Ca and Mg in soil samples were obtained by vibrating extraction. The results show that the data of this method have high degree of accuracy, indicating that the method is suitable for the exchangeable Ca and Mg determination in all kinds of soil. At the same time, compared with existing methods, the new method has the advantage of less reagent amount, simple process, and capacity to handle bulk detection. |
