Abstract:: The effects of balanced fertilization and foliar fertilizer spraying on the yield，quality，physiology，tree growth and development of jujube etc were experimented mainly based on the analysis of soil physiochemical properties and nutrient content in the jujube orchid and using four to six years old ‘Tongxinyuanzao’ jujube trees as material in the arid region of central Ningxia.The results indicated that，the soil were seriously short of organic matter，available nitrogen，available phosphorus，the micro-element of iron and manganese in the ‘Tongxinyuanzao’ jujube orchard.Meanwhile the available potassium was also lacking.But the balanced fertilization was an important measure to increase soil nutrition and jujube tree nutrition on dry land.Compared with the control of incomplete fertilization，the single fruit weight of four kinds of balanced fertilization was increased by 3.35-4.35 g，the two-year average yield of individual was increased by 8.23-9.15 times，and the yield of 667 m2 of total row fertilization reached to 247.7 kg in 2015，the leaf area and chlorophyllcontent were respectively increased by 65.7% and 34.4%，by balanced fertilization+foliar fertilizer spraying，under the base of 60 m3 artificial water of 667 m2 per year.In 2014，the yield of jujube tree was increased by 59.2%，based on balanced fertilization with foliar fertilizer spraying.
