Abstract
A field experiment with different drip irrigation patterns was conducted in Heilonggang region,Hebei Province,China in the 2010–2011 and 2011–2012 winter wheat growing seasons to develop suitable drip irrigation schedule in this region.The yields and water use efficiencies(WUE) of wheat in different drip irrigation treatments with flood irrigation as control were compared under total water supplies of 225,180,150,and 120 mm,respectively.Under the condition of 225 mm irrigation,drip irrigation and irrigation frequency(1–3 times) had no significant difference in effect on yield and WUE.Drip irrigation resulted in 45–105 mm reduction of irrigation amount as compared to the control,with no significant yield loss,and a significant increase of WUE.Correlation analysis indicated that the contribution of yield components showed a sequence of spike number1000-grain weightgrain number per spike.These results showed that drip irrigation technique should have potentials of water saving and yield stability in wheat production of the experimental region.
