Abstract:To study the suitable strategies of saline water irrigation for crops,a field experiment was conducted in Jinghai County of Tianjin City.Data were collected to analyze the effects of saline water irrigation onsalt dynamics and crop yield.The results showed that with saline water irrigation,the application of soilamendment increased soil permeability coefficient,reduced soil pH value and EC(electrical conductivity ofsoil solution),and decreased the salt content.No salt accumulation was found in 0-60cm soil during theexperiment.Meanwhile,the amendment increased wheat shoot number,grain number per shoot of maize andcrop yields significantly.Using saline water with degree of mineralization at 3.7g/L for irrigation with soilamendment is the recommended irrigation mode for crops in this region.
