摘要
对土壤磁效应的研究表明,磁场可引起土壤理化性质,机械物理性质变化,在适宜的外加磁场作用下,土壤电位,土壤比表面,土水势,膨胀量,剪切力下降;土壤胶体电荷密度升高,土壤微团聚化作用增强,土壤结构状况有所改善。
The effects of magnetic field on some soil were studied systematically. The results indicated that magnetic field can made soil physico-chemical properties and soil mechanical physical properties change. Under treated with appropriate magnetic field intensity, the soil Zeta-potential, soil specific surface, soil water holding power, soil swelling capacity and soil shearing strenth reduced. Aggregation increased. Soil structure can be improved in some way.
