中文摘要：

用连续液流法研究水处理土样对K^＋的吸附动力学特性，并采用5种动力学方程模拟土样中K^＋吸附过程，结果表明：一级动力学模型对土壤中K^＋吸附过程模拟效果最好，长期定位施肥对土壤中钾素的吸附过程动力学影响显著；不同施肥处理中，土壤对K^＋的吸附平衡时间及平衡吸附量差异显著，单施有机肥或有机肥与氮肥配施能增加土壤对钾素的吸附量。

英文摘要：

The characteristics of K^＋ adsorbing kinetics of soil treated by water on long - term fertilization were studied by the liquid flow technique. After simulating by 5 kinds of kinetic equations, it was indicated that first - order kinetic equation was the best model for K^＋ adsorption in soil. The results shown that there were great effects of long - term located fertilization on soil potassium adsorption kinetics, great differences on the time and capacity of K^＋ e-quilibrium adsorption in different treatments, also that the quantity of potassium equilibrium adsorption increased in the treatment of organic manure or the treatment of organic manure and nitrogen fertilizer.
