Study on the Response to Growing-power of the European Oak to the Change in Exchangeable Cation in Topsoil

土壤阳离子交换量的变化与欧洲栎生长势的研究

The composition of exchangeable cation and the soil nutrient content can be used as the indexes to evaluate soil chemical fertility evolution, especially the former is more important.

交换性阳离子组成、养分全量及速效含量可作为评价红粘土红壤化学肥力演化的指标。

From the results of cation exchange of four components, the exchangeable cation of the red clay is mainly Ca2+, and the total amount of exchangeable cations is lower or much lower than the cation exchange capacity.

从四个盐基的交换结果组成来看，红色黏土的交换性阳离子以交换性Ca2+为主，而且交换性阳离子盐基总量低于或远低于阳离子交换量。

However, the low exchangeable caution of cation is one of the reason about spruce death.

但是土壤阳离子代换量低可能是云杉死亡的一个因子.

The contents of total nitrogen, total phosphorus, content of exchangeable cation ( CEC) and C/ N specific ratio were all improved.

施用有机肥的土壤全氮、全磷、重组磷及C/N比均呈提高趋势，pH值降低，其原土和重组复合体的阳离子交换量较高。

Many factors lead the clay mineral to swell and disperse, it is not only determined the composition and structure of glues on the mineral but also related to the factors of particle surface exchangeable cation ingredient, the dispersion medium nature and son on.

引起粘土矿物膨胀、分散的因素较多，除取决于组成粘上矿物的组分和结构外，还与颗粒表面交换阳离子成分、分散介质性质等有关。
