Abstract In order to achieve an efficient use of water and fertilizer in saline soil in Xinjiang region, used local "Jun-jujube of the 8 years" as test materials, the effects of water and fertilizer management on soil water-salt movement and photosynthetic characteristic of drip-irrigation jujube were studied by experimented with field. The results showed that irrigation had significant effect on soil moisture merely in the stage of jujube(0-40 cm soil layer),while water-fertilizer coupling had significant effect on jujube soil water content in the whole growth period(0-40 cm and 40-100 cm soil layer). In 0-40 cm, irrigation and water-fertilizer coupling had significant effect on soil salt content in the whole growth period, fertilization had significant effect on soil salt content in the stage of the new tip. In 40-100 cm, water-fertilizer coupling was significant for soil salt content. High irrigation had good effect on the surface soil water holding capacity and water leaching of salinity. Increased fertilization could increase the surface salt.The difference in the soil salt accumulation between the start and end of the experiment indicatied a desalination process during the growth period. Irrigation and water-fertilizer interaction were significant for net photosynthetic rate(Pn), transpiration rate(Tr)and water use efficiency(WUE)in jujube leaves. The net photosynthetic rate and transpiration rate of jujube could achieve a higher level under W2F1 treatment(820 mm,200-100-150 kg/hm2).Water use efficiency was superior under W3F3 treatment(1020 mm,600-300-450 kg/hm2), but the discrepancy in the two treatments had no statistics significance.
