Abstract: In order to research the water management rule of winter wheat water-saving irrigation,during 2014-2015 and 2015-2016,the demonstration research on simplified cultivation model of winter wheat with thousand catties by watering once was conducted with soil moisture for seeding technical measures. This experiment was tested in the condition of rainfall in the whole growth period of winter wheat was not significant difference with that of conventional year. Result showed that the average rainfall in the whole growth period of winter wheat was 132.4 mm in Shijiazhuang region in the recent ten years. It only accounted for roughly one-third of the average water requirement. Without considering water active layer from 0 to 40 cm, the soil moisture content under 40 cm was increasing gradually in a trend of soil layer down. The soil moisture content in different layers was over the wilting coefficient before winter wheat jointing time. The average water consumption in the whole growth period of winter wheat under the mode of thousand catties by watering once was 4 404.0 m₃/hm₂. The average water consumption of soil was 1 852.5 m₃/hm₂. Water consumption in the whole growth period was close to that of the conventional irrigation mode. The cultivation model of winter wheat with thousand catties by watering once in the middle and south of Hebei Province realized the unity of water-saving and high-yielding. Winter wheat irrigation water should be over 1 200 m₃ / hm₂. The total water consumption in whole growth period of winter wheat should be more than 4 650 m₃ / hm₂.
