[Objective] To explore the mechanism of water saving and water control methods to regulate the efficient use efficiency of apple water, and optimize the management methods of water saving, high yield and income increase in Weibei apple main producing area. [Methods] The eight-year-old 'Yanfu 3 /T337' apple tree was selected from the experimental station of Tiefu town, Xian County, Xianyang City, Shaanxi Province Xi 'an Fruit Friends Association, and two irrigation water levels were set: Full irrigation (relative water content of soil after irrigation: 75%) and slight deficit irrigation (relative water content of soil after irrigation: 50%).There were four irrigation modes: full irrigation at both fruits growing and expanding stages (CK), light deficit irrigation at both fruits growing and expanding stages (W1), light deficit irrigation at fruits growing and expanding stages (W2), and light deficit irrigation at fruits growing and expanding stages (W3). Spring shoot growth index, fruit quality index and fruit yield index were determined, to calculate water use efficiency, irrigation water use efficiency and fruit comprehensive evaluation satisfaction to determine the best deficit irrigation method. [Results] (1) There were no significant differences in shoot length and leaf chlorophyll relative content (SPAD) among different irrigation modes, but the diameter of spring shoot decreased significantly under different deficit irrigation. (2) Compared with CK, the single fruit weight was significantly reduced by 10.3% under W1 water deficit irrigation treatment, the titrable acid content of fruit was significantly reduced by 14.7% under W2 treatment, and the fruit shape index and soluble solid content were not significantly changed under the three water deficit treatments. (3) W1 deficit irrigation treatment can significantly increase the peel yellow value b*, W2 irrigation treatment can significantly increase the peel color saturation C*, but deficit irrigation treatment has no significant effect on the peel brightness value L* and red green value a*. (4) Compared with CK, fruit yield decreased by 13.4%-24.7% under each treatment, but only W1 treatment reached a significant level; The fruit tree irrigation water use efficiency increased in different degrees in each deficit irrigation treatment, but only W1 treatment significantly increased by 38.0%. There was no significant difference in water consumption and water use efficiency of fruit trees under each treatment. The satisfaction of fruit comprehensive evaluation was W2 > CK > W3（W1）. [Conclusion] According to the comprehensive evaluation, the comprehensive evaluation satisfaction of apples in Weibei area of Shaanxi province was the highest under mild deficit irrigation in growth period and full irrigation in expansion period (W2). There was no significant change in fruit yield and single fruit weight, but the fruit quality was better and the water use efficiency of fruit trees was higher.
