摘要
土壤对磷的吸附与硅的吸附比较相似，吸附磷量多的土壤吸附硅的量也较多，但不同土壤吸附磷、硅的能力差异较大。两种吸附与Ｌａｎｇｍｕｉｒ等温吸附方程均达极显著相关。土壤吸附硅的能力远高于对磷的吸附能力，对硅的缓冲能力一般也高于对磷的缓冲能力，其对磷、硅的吸附能力主要受土壤物理性粘粒含量及土壤活性铁、活性铝的含量的影响。
Soil adsorption to P and Si was similar except with different soil.They are relevant to Langmuir isotherm adsorption equation.Soil adsorption to Si was far higher than soil adsorption to P. Soil adsorption to P and Si are mainly influenced by content blow 0.01mm Soil particle and the contnt of active iron and active aluminum.
