摘要
研究了莱阳几种不同土壤磷等温吸附的情况，并对影响土壤等温吸附特性的因素做了初步探讨。研究指出：实测磷吸附曲线与简单的Ｌａｎｇｍｕｉｒ等温吸附方程极为吻合，供试样品的相关系数均达到极为显著水平。土壤物理性粘粒含量显著影响土壤最大吸磷量（Ｘｍ）。
This essay deals with the features of phosphate adsorption isotherm for some topsoilsin Laiyang and the factors affecting these features. The results show that the curves of practical measured phosphate adsorption are identical with the simple Langmuir equation well,and the correlation coefficients of all samples are significantly at the 0.01 probality level.The content of physical clay affected the maximum quantity of phosphate adsorption greatly
