摘要
研究结果表明，在NH4+加入量较低时，随着NH4+加入量的增加，土壤对NH4+的吸附量呈线性增加，但NH4+的吸附率呈下降趋势；三种土壤对NH4+吸附量大小顺序为们土＞黄褐土＞水稻土．
The NH4+ adsorption properties of the three kinds of soils were studied. The results showed that soil NH4+ adsorption capacity increased linearly as the NHt added amount, but there was a descent tremd of the rate of NH: adsorption; The NH: adsorption capacity by theree kinds of soils showed the highest on Fluvo-aquic soil, the lowest on Paddy soil.
