| 摘 要： | 探讨了磁处理棕壤对磷吸附-解吸的影响,结果表明:外加磁场处理棕壤后磷的吸附量降低,促进了磷的解吸。棕壤不同粒级磁化后(0.002~0.005mm除外)吸附量基本都减少,而<0.002mm粒级和0.005~0.01mm粒级对吸附量减少起主要作用。

| Abstract: | This paper studied the effects of magnetic treatment brown soil on phosphate adsorption and desorption.The results showed that adsorptive capacity of magnetic treatment brown soil is down, desorptive capacity is up. Adsorptive capacity of different particle fraction of magnetic brown soil (except 0.002~0.005mm) basically decease, adsorptive capacity of <0.002mm part and 0.005~0.001mm part are major. |
