磁场对土壤理化性质的影响

 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。

EFFECT OF MAGNETIC TREATMENT ON SOIL PHYSICO-CHEMICAL PROPERTIES

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.
