Title: Primary Report on Study of Irrigation Pattern for Water-saving and High-yield in Winter Wheat
Abstract: In this paper,study on water-saving irrigation experiment of winter wheat in arid oasis area of Xinjiang was conducted.The impact of different water supply treatments on yield and water utilized efficiency(WUE) of winter,wheat was analyzed in order to provide a basis for establishing optimum irrigation mode which could increase the yield and improve water utilized efficiency.The experiment results indicated that the ratio of soil water to total water consumption was at 27.8% ~ 91.2%;the ratio of water volume irrigation to total water consumption was at 28.5% ~ 68.0%;the ratio of the precipitation to total water consumption was at 4.2%~8.8%.Along with the increase of times and water volume of irrigation,the water obsorbed by winter wheat was gradually decreased.The best irrigation combination pattern at pilot area was that(1)At the beginning of spring,when the jointing and flowering stages started,two-irrigation was made,yield obtained by combination treatment was 6 813 kg/hm~2,water utilized efficiency was 1.47 kg/m~3;(2)At the beginning of spring,when jointing,booting and filling stages started,three-irrigation was made,yield obtained by combination treatment was 7 393.5 kg/hm~2,water utilized efficieney was 1.40 kg/m~3.
