In order to explore the coupling scheme of water and fertilizer suitable for drip irrigation to improve the quality and efficiency of Jun jujube， 10 a Jun jujube of 224 regiment in Kunyu City， a typical self-pressure irrigation area in Southern Xinjiang was studied.Referring to the local practice， the irrigation amount of 770 mm and the fertilization amount of 1 125 kg / km² were used as the control， a two-factor three-level plot trial was conducted with water（W1，540 mm；W2，630 mm；W3，720 mm）， chemical fertilizer（F1，562.5 kg/hm²；F2，810 kg/hm²；F3，1 080 kg/hm²）.To explore the response law of new shoot， bearing branch， photosynthetic characteristics and yield of Jun jujube under drip irrigation in Southern Xinjiang to water and fertilizer coupling.The results showed that the effects of irrigation， fertilization and water-fertilizer interaction on leaf net photosynthetic rate（P_n）， transpiration rate（T_r）， stomatal conductance（G_s）， intercellular CO₂ concentration（C_i）， new shoots and bearing branch were in the order of irrigation>fertilization>water-fertilizer interaction.The effects on yield and irrigation water use efficiency（IWUE）were water and fertilizer interaction>irrigation>fertilization.The effect on fertilizer partial factor productivity（PFP） was water and fertilizer interaction>fertilization>irrigation.The single fruit weight， vertical and horizontal diameter of Jun jujube showed fertilization>irrigation>water and fertilizer interaction.The effect on fruit shape index was fertilization>water and fertilizer interaction>irrigation.The results showed that W3F2 was the best treatment for shoot and bearing， W2F3 was the best treatment for yield and IWUE， W2F2 was the best treatment for P_n， T_r， G_s， single fruit weight， vertical and horizontal diameter， W3F1 was the best treatment for PFP.This study can provide scientific basis for water and fertilizer management of dripper Jun jujube in Southern Xinjiang.
