- Abstract:
-
By designing different treatments of water (W) and N under drip irrigation, the coupling influence of water and N on yield and quality of Huizao jujube was studied through the establishment and analysis of model. The results show that it can reduce the single fruit weight to irrigate more water to soil in range of designed level, but it can increase the yield to apply more fertilizer N. If the contents of water and N are all much higher in soil, they can reduce the contents of revertose and vitamin C in fruit of Huizao jujube. But the content of protein is increased with fertilizer N increasing. The role of water and N to yield, contents of revertose, vitamin C and protein in fruit of Huizao jujube is in order of N>W, the interaction effect of water and N is coordination for yield, but there is no interaction effect of water and N for contents of revertose, vitamin C and protein. Taking the yield and quality as optimal composite scheme, the quantity of watering is 4500~5250 m3/hm2, the quantity of N is 225~375 kg/hm2.
