The same fertilization strategy was adopted in all the treatments. The local rotten chicken manure was applied to the roots of jujubes with the dose of 1200kg/666.7m2 as organic Fertilizer. Inorganic fertilizers, including urea, diammonium phosphate and potassium chloride, were applied separately at each growth stage. Basal application with the dose of 40kg/666.7m2 was adopted to all the phosphate fertilizer triple superphosphate. 50% of potassium sulfate was used as basal application, while the other was topdressed under drip irrigation with the dose of 60kg/666.7m2. Salt accumulation around roots of jujubes caused by drip irrigation with saline water was relieved by desalination irrigation after the jujube's harvest time in autumn, among which 40% of the niitrogen fertilizer urea was used as basal application, while the other was topdressed under drip irrigation with the dose of 70kg/666.7m2.
