Abstract: The vegetable production in Bashang Area of Hebei is facing the problem of low water use efficiency caused by extensive irrigation management. It is urgent to build a high-yield, high-quality and water-saving collaborative precision irrigation mode. In this study, the Chinese cabbage in this area was taken as the research object, and different irrigation thresholds were set at seedling stage, rosette stage and heading stage: Among them, the total irrigation volume of W1 80%−95% field capacity (FC) at seedling stage, 80%−95% FC at rosette stage, and 80%−90% FC at heading stage is 170.5 mm. The total irrigation volume of W2 (80%−90% FC at seedling stage, 70%−90% FC at rosette stage, 70%−85% FC at heading stage) is 135.1 mm. The total irrigation volume of W3 (80%−100% FC at seedling stage, 60%−100% FC at rosette stage, 60%−100% FC at heading stage) is 210.4 mm, to explore the effects of soil water threshold regulation of drip irrigation under film on crop water consumption, yield and quality. The results indicated that, compared with W3 (the highest irrigation amount), the irrigation amount and evapotranspiration of W2 decreased by 35.7% and 18.1%, respectively, with no significant reduction in the yields of untrimmed and trimmed vegetables; The irrigation and evapotranspiration of W1 decreased by 39.8 mm and 25.3 mm, respectively, resulting in a 10.0% decrease in trimmed vegetable yield. Compared with the three irrigation schemes, the water use efficiency of W2 increased by 25.2% and 20.1% respectively compared to W1 and W3, and the irrigation water use efficiency increased by 40.8% and 53% respectively compared to W1 and W3. Moreover, W2 had the best quality (nitrate content 1422.7 mg/kg, vitamin C 250.5 mg/kg). In general, the W2 model can meet the soil water demand of different growth stages of Chinese cabbage, which is consistent with the water demand law of crops. By selecting the appropriate soil water threshold and irrigation amount through precise water control, the evapotranspiration water consumption is reduced under the premise of ensuring the yield and quality of pure vegetables and vegetables, and the synergistic improvement of water use efficiency WUE and irrigation water use efficiency IWUE is realized. The results of this study provide an important theoretical basis and technical support for the construction of efficient water-saving production system of Chinese cabbage in Bashang Plateau in cold and arid regions.
