Water infiltration under water supply of negative hydraulic heads is suited to irrigation in the deserts around Qinghai lake. According to water infiltration principle, one kind of water economizer is designed. Considering the water consumption of the plant, the water delivery of cotton, property of water capillary conductivity in sand, water conductivity magnitude and the position where water infiltration will begin from the water economizer are designed.
