| Abstract: |
| Field experiment of border irrigation was conducted, have researched the water requirement of winter wheat during the major growing periods, and analyzed the effect of different border irrigation methods to the soil water and water use efficiency of winter wheat, evaluated the irrigation quality and the benefits under different treatment of border irrigation. The results indicated that: The maximal water requirement was at the filling stage of winter wheat. In contrast with the flood irrigation treatment (as CK), the irrigation uniformity and irrigation efficiency of winter wheat by the border irrigation with the plot of 30 m×3 m was the highest, reached 93.33% and 84.46%, respectively. The water consumtion was decreased 5.96%, the yield was increased 25.03%, water use efficiency was increased 33.24%, and the added profit was 1561.61 yuan·hm-2. Therefore, according to the local production situation of the winter wheat boundary irrigation area, the appropriate border irrigation method was recommended that the inflow rate per unit width and border width and length are 5 L·m-1·s-1， 3 m and 30 m。 |
