| Abstract: | By field experiment on boundary irrigation,water demand and its profit and loss of spring wheat during its growing period were analyzed,the irrigation efficiency and the water-saving effect were appraised on different boundary irrigation modes.Results showed that the water use efficiency of boundary irrigation area of 50m × 2m was 26.78% higher than that of the flooding(CK),the production was 13.08% higher than it.The field experiment on boundary irrigation had water-saving effect.Better economic results should be achieved by reasonable use and promotion based on the actual production. |
