摘    要: 研究了磁场对土壤理化性质的影响。结果表明,在磁场作用下,土壤胶体ξ电位降低,电荷密度有所提高,土壤持水力,膨胀量下降;土壤微团聚化作用增强,<0.01毫米粒径的微团聚体数量减少,0.01-0.05毫米粒径的微团聚体数量增加;土壤比表面减少,土壤粘结力降低,土壤物理性质得到改善。

关 键 词:磁处理  土壤磁学

Abstract:This paper deals with the effect of magnetic treatment on Physieo-Chemieal properties of soil. The resutls are summarized as follows:Magnetic energy can make the water retention ability, swelling capacity specific surface, Zeta-potential of colloid and cohesive force of brown earth, cinnamon soil, black soil and chernozem reduce; intensity of electric charge increase. Magnetic treatment can promote aggregation. Microaggregate analysis showed that the amount of soil particles 0.001mm and 0.01mm reduced and greater particles 0.01-0.05mm increased certainly under magnetic treatment. Therefore, this favours soil fertility improvement, tillage resistance dropping and tillage quality improvement. The effect of magnetic treatment on soil Physico-Chemical properties will be kept over one year.
Keywords:Magnetic treatment  Soil magnetism
