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。
The effects of magnetic treatment of brown soil on phosphorus adsorption and desorption were discussed. The results showed that phosphorus adsorption decreased after browning treatment and the desorption of phosphorus was promoted. After the different grades of brown earth were magnetized (except for 0.002 ~ 0.005mm), the adsorption amount of brown soil decreased. However, the grain size of <0.002mm and the grain size of 0.005 ~ 0.01mm played a major role in reducing the adsorption amount.
