Slight saline water irrigation systems for winter wheat

Experiment of slight saline water irrigation was carried out to analyze the impacts of different irrigation quotas on water use efficiency, salt-water transfer and wheat yield at the ecological experiment station of Nanpi in Hebei Province. The results indicated that the suitable quota of saline water irrigation was 120 m³/667 m² considering the water use efficiency, salt balance and crop water requirement as a whole. The study supplies a basis for reasonable exploitation and utilization of underground slight saline water irrigation.
