摘要
可在不同检测地区利用春季返盐季节刮取盐皮,精制烘干,配制系列标准溶液用电导法测定,做出效应方程,以此计算待测样品含盐量。其结果较接近于田间状况,且方法简便、快捷。
By scraping salts in spring in different districts,refining,oven drying and compounding a series of standard solutions,salt contents of those standard solutions were measured by the electric conductivity method and effect equation was made, by which sample's salt content needing measurement was computed.The measurement results are colse to field situation.This method is simple,convenient,rapid and is fit for measuring soluble salts in soil of Tianjin district.
