阳离子交换量 abbr. CEC
[土壤] cation exchange capacity
- 季节雨林土壤为粗骨性赤红壤,水热条件好,有机质等养分含量丰富,阳离子交换量较高。
The soil of seasonal rain forest was skeleton lateritic red earth, with desirable water and heat, and abundant content of organic matter, and high cation exchange capacity. - 研究结果表明,污泥堆肥与滩涂土混配后,土壤声、电导率、阳离子交换量等理化指标得到改善;营养得到补充,肥力提高明显;
Results show that chemical and physical properties of soils such as pH, conductibility , cation exchange capacity as well as the nutrition and fertility are improved when mixed with sludge. - 选择黄土高原地区典型人工林为研究对象,以土壤有机质和阳离子交换量(CEC)等理化特性为评价指标,研究了不同人工林对林地土壤肥力的影响。
With the typical plantations on Loess plateau as the subject, the change of soil fertility was studied in different types of plantations according to soil organic matter, nutrition and CEC.
