摘  要:
针对滨海地区吹填土的高盐分和质地粘重,从改善物理性状和降低盐分入手,通过添加不同量的脱硫石膏进行不同处理的脱盐试验,结果显示:3个处理都能够改善吹填土粘重的物理性状,有效降低吹填土中有害离子(Cl-和Na+)的含量,脱盐后的吹填土无次生碱化现象。3个处理中5%脱硫石膏和5%有机肥较单纯施用脱硫石膏的处理脱盐显著,且改良后的碱化指标明显低于另两个单纯施用脱硫石膏的处理。

摘  要:
Contraposed to high salinity and viscidity of the dredger fill,incoordination DSG was used speediness desalting,which DSG was 5%,10% and 5% DSG mixed 5% organic fertilizer of the differ treat to desalting.The results indicated that the differerent all improved dredger fill character,which not only reduced the Cl-and Na+ in the dredger fill,but also no desalting alkalization.The mixed organic fertilizer treat for desalting was better than another,further more basification factor under than another.
