摘要
利用质量法和电导率法对30个土壤样品水溶性全盐量进行测定,结果表明,两种测定方法建立的土壤全盐量回归方程,线性关系明显,精确度高,重演性好。可通过回归方程直接将电导率测试值转换为土壤水溶性全盐量实现速测。
The soil samples for 30 total salt of water-soluble were determined by use the method of quality and conductivity, the result showed that regression equation with full water-soluble build by two kind of method. There are features like the linear relationship, high precision and good reproducibility, a higher total salt content of water-soluble soil. Therefore, by contrasting and analyzing of the two test methods, the author established a regression equation between the general method of testing quality and the conductivity testing method.
