【Abstract】 To improve use ratio of water in protected agriculture, the system of purification and recycling uses of irrigation water was designed in the flat broad irrigation system. The paper introduced the constitution, the principle of water-saving irrigation and working process of the system in details. It was resulted from theoretic analysis that the system has high use ratios of input water, irrigation water and precipitation. So it 憇 a new effective approach of agricultural water-saving irrigation.更多还原
