| 摘 要： | A study on the effect of applied magnetic field was performed with six types of soils collected from northeastern China.Magnetic field was found to cause changes of soil physico-chemical properties and soil enzyme activities.An appropriate applied magnetic field could cut down soil zeta-potential,soil specific surface,soil water potential and soil swelling capacity;raise the charge density on soil colloids and the activities of invertase,hydrogen peroxidase and amylase in the soils;enhance soil aggregation and improve soil structural status and soil water-releasing capability.
