Abstract:
Under the condition of non-irrigation，taking the 9-year-old pear jujube (Ziziphus jujube Mill.) trees which grafted on wild jujube (Ziziphus jujube Mill.var.spinosa (Bunge) Hu ex H.F.Chow.) as test material，different dry farming technologies were set，which included water saving type pruning technology，bamboo type poly ditch technology，and the different effects of each treatment on pear jujube fruitful bearing branchlet，fruit setting and yield were compared.The results showed that water saving pruning and bamboo type contour ditch，either singly or in combination，could increase significantly the number of fruitful bearing branchlet，fruit setting and yield.Compared with the control，water saving pruning (HL) could raise the yield by 83.14%，and bamboo type poly ditch (CJ) could raise by 38.44%，while the treatment (HJ)，combining the HL and CJ technologies，harvested the most and the yield by 155.00% of the control.In Loess Hilly Regions in Northern Shaanxi，under the condition of nonirrigation，the saving water pruning technology could play a main positive role in raising pear jujube yield，especially combining the bamboo type contour ditch technology.
