Field Test Study on Salt Water Irrigation Systems in the High Yielding Cultivation of Winter Wheat

A salt water irrigation test was carried out to study soil salt water dynamics and its effect on crop yields under conditions of different salt water irrigation schedule and to further study the suitable schedule of salt water irrigation in the Huqu irrigation area of Yuncheng Basin. The results showed that the suitable quota of salt water irrigation ranged from 825 to 975 m³/hm², the suitable irrigation was 4 times in the area with a mineralization degree changing from 1 to 3 g/L, 2～3 times in the area with a mineralization degree ranging from 3 to 5 g/L, and 1 times in the area with a mineralization degree ranging from 5 to 7 g/L.
