在粘性土开放性及封闭性单向冻结过程中,盐分向土的正冻部分迁移,从而使土柱的冻结部分盐渍化程度较冻前增高;在水溶液及良渗透性土冻结时,情况正相反。在确定季节冻结区盐渍土地段的灌溉制度时应考虑到这一规律。
During the open and closed unidirectional cohesion of clay, the salt migrated to the part of the soil in the normal freezing so that the frozen part of the soil column became salinized more than before freezing. When the aqueous solution and the well of impervious material froze, On the contrary. This rule should be taken into account in the determination of irrigation regimes in salty soil sections of seasonally frozen areas.
