Study on Water-saving Potential and Incentive Systems in Southern Water-lifting Irrigation Districts

Abstract

It is of immense significance for agricultural water-saving work to stimulate the initiative of water users and enhance their water-saving awareness. Focusing on the southern water-lifting irrigation districts, this paper employs various water-saving potential analysis methods(water quota method and Irrigation test method) to calculate the water-saving potential of irrigation districts. The irrigation control indexes of the single-season rice trial in the experimental station adopt conventional irrigation mode. Based on irrigation test results, different water-saving grades are determined, and then, water-saving rewards are granted accordingly. The establishment of water-saving incentive systems shows positive effects on promoting water and energy conservation at pump stations, facilitating the benign operation of agricultural water conservancy projects.
