中文摘要：
研究了陕西关中地区红油土和淋溶褐土耕层土壤对分离的有机肥提取液中可溶性有机氮、碳（SON和SOC）的吸附特性．结果表明：原始物质吸附等温线方程可以反映土壤对可溶性有机氮、碳的吸附特性，土壤吸附SON、SOC的数量与它们各自加入的量呈极显著线性关系．从原始物质吸附等温线方程的分配系数m看，淋溶褐土对SON、SOC的吸附能力强于红油土．红油土对SON、SOC的平均吸附率分别为24．3％和18．8％，淋溶褐土则分别为38．3％和18．6％：两种类型土壤对SON和SOC的吸附能力较低，说明它们在土壤中具有较强的移动性；土壤对SOC的吸附能力弱于SON，说明SOC更易于从土壤中流失．
英文摘要：
In this paper, soluble organic carbon （SOC） and nitrogen （SON） were extracted from manure, and their adsorption characteristics in Argosols and Anthrosols in Guanzhong region of Shaanxi Province were investigated. The results showed that the adsorption of SON and SOC in the two soils could be fitted by initial mass isotherm model, and the adsorbed amounts of SON and SOC had a significant linear relationship with the initial concentrations of SON and SOC added into soils. The partition coefficient, m of the initial mass isotherm model, indicated that Argosols had a higher adsorbility than Anthrosols. The average adsorption rates of SON and SOC in Anthrosols were 24. 3% and 18.8%, and those in Argosols were 38.3% and 18.6%, respectively. The low adsorption rates of SON and SOC indicated their high mobility in the two soils, and more SON was ad- sorbed than SOC suggested the higher potential of SOC leaching from soil.
