In this study, a 2-factor and 5-level quadratic orthogonal rotated composite experimental design was employed to investigate the effects of water fertilizer coupling on yield quality drip irrigated Chinese jujube in an extreme arid region. The results showed that both had significant important influences reasonable effective fertigation could bring high good quality. Insufficient would affect nutrient uptake result decrease yield. Similarly, inadequate nutrients lead maldevelopment finally When irrigation at relatively low level, reasonably increasing application improve biological trails jujube, while over-fertilization inhibit growth when level. Under conditions, pursued economic goal, suitable determined as amount 7800 m³/hm², urea 456.45 kg/hm² potassium dihydrogen phosphate 755.4 kg/hm²; recommended 652.2 1079.25 kg/hm².
