| 摘 要： | 研究结果表明,在磁场作用下,土壤比表面减小,渗透系数增加;<0.001mm的微团聚体数量减小,0.001～0.005mm的微团聚体数量增加;速效氮释放能力提高,磁处理后的(土娄)土粘化层水势提高,膨胀度下降,耕作层水势降低,膨胀度上升;土壤物理性质得到改善。

| Abstract: | Research results showed as follows: magnetic energy can make the soil specific surface reduce, permeability coefficient and fast netrogen of soil increase;microaggregate analysis showed that the amount of soil particles below 0.001 mm reduced and greater perticles 0.001~0.005 mm increased certainly under magnetic treatment. By contrast to the tilled horizon. Water potential of cohesive horizon increased and swelling capecity reduced under magnetic treatment. Improvement of the soil physico-chemical properties. |
