Thereinto, drip irrigation is divided into three treatments of different ration. Tectorial and untectorial treatment are adopted to semifixation spray irrigation. At the same time, seepage-preventing trial is done. By study of one growth season, it shows that the indexes, Comparing with flood irrigation, water-saving technique has the effect of increasing production and harvest, economizing water, energy sources and field, saving work, time and power. It has best significance difference among unit yield of using different irrigation ways. The highest yield is in irrigation treatment of 80% field moisture capacity, it is secondary in seepage-preventing ditch irrigation treatment and is the lowest in spray irrigation treatment. Drip irrigation increase yield 4.0%~25.9%,Seepage-preventing ditch irrigation increase yield 17.5%, and spray irrigation decrease yield 22.4～37.8% comparing with flood irrigation.
