The control treatment(irrigation with fresh water,CK),irrigation with saline water(SW),irrigation with saline water ice(MI),and irrigation with saline water ice and wheat straw mulch(MI+SW) was conducted to study the mechanism of soil water,salt and ion movement using soil column modeling experiment based on the melting process.The results showed that compared to irrigation with fresh water,soil salinity was more under the saline water treatment with the salt aggregation in the surface.However,irrigation wi...
