摘要
通过对青海主要土壤类型剖面的有机质、机械组成、阳离子交换量三者之间的关系分析。结果表明:土壤阳离子交换量与土壤有机质和土壤机械组成有着密切的关系。随深度的增加有机质与交换量的相关性增强。土壤粘粒含量越高,阳离子交换量越大。
The relationship was analysised between organic matter,soil granular composition and cation exchange capacity(CEC) in Qinghai major soil types.The results showed,there were relationship closely between them.The correlation were strengthened between organic matter and CEC with soil depth.The higher content of clay the more CEC in soil.
