以两种元素的研究为例介绍了用层析纸研究原状土壤剖面的方法,其中层析纸复印法能测剖面微区元素的释放速率,层析纸电解法能测剖面微区速效磷的释放容量.
Taking the two elements as an example, the paper introduces the method of studying the original soil profile by using the chromatographic paper, in which the papermaking photocopy method can measure the release rate of the micro-elements in the profile and the paper-paper electrolytic method can measure the available phosphorus Release capacity.
