- Abstract:
-
Water-salt dynamic of five different platform fields by insulating hidden of two layers were researched in coastal argillaceous saline land of Tangshan from the prepared of platform field and the date collection of the water-salt dynamic.Results showed that,the experimental plot is easily lead to salt accumulated which the water table was above the critical depth.There is a close relation between the water content and salt content,from spring to autumn,the ‘down-up’ process of water and salt appears in soil surface layer,it is inversely which water showed ’up-down’ and the salt changed as opposite trend in soil middle and deep layer.After the build of platform field,the soil of platform field which from heavey salinized soil into slinized soil is appropriate to growth by saline-alkali tolerant tree species.The effect of desalination is obvious in the platform field which lying the insulating hidden layers.The best effect of desalination is the layers by grass and gravel which the desalination ratio as high as 30.46%,then load decreased with the order of grass and slag,grass and plastic film,grass and garbage architecture,control platform field.
