二种测定土壤全磷含量方法测定效率的比较分析

Analysis and Comparison on Efficiency Determination of Soil Total Phosphorus Content with Two Kinds of Methods

摘要: 土壤中磷的分析是土壤农化分析的主要项目之一。本文介绍了显色方法测定土壤全磷的方法，并用回归曲线法讨论了方法的可行性，结果显示具有较高的测定精度和较高的分析速度，方便了大批量的土壤全磷分析工作，测试结果能够满足对土壤环境样品中磷含量的监测要求。

Abstract: To analyze soil phosphorus is one of the main items to soil in agricultural chemistry. This paper described the technique of determination of total soil phosphorus by colorimetry methods, and discussed the feasibility of the method with regression curve method. It was higher accuracy and rapider speed, and improved work effciency. And this can also enhance the accuracy and precision of the testing result in a certain degree and facilitate a large number of soil phosphorus analysis. It was also simple, sensitive and with good selectivity. It can be widely used for the environmental monitoring of phosphorus content in soil.
