摘要： 1984～1988年在中国水稻研究所实验场排水与其它农业措施相结合，采用节水灌溉措施和高产灌溉制度，综合考虑对田面水、土壤水、地下水和雨水的统一管理利用和合理调节控制，通过大田、小区、测坑试验和生产实践，提出了适合当地条件的节水高产灌排方式、地下水埋深度和排水量。这种水综合运用，既可节约灌溉用水量，减少灌水次数，还可降低排涝水量，减轻排涝能耗费用。

Abstract: A 5-year (1984-1988) research aimed at the optimum drainage-irrigation model that makes the best utilization of rainfall to effectuate a high yield with a least amount of water consumption in irrigation and discharge in drainage, has been carried out on plots at experimental station of CNRRI, Hangzhou. Among the treatments of the test, various water depth over the paddy under irrigation and depth to water within the soil under drainage are specified for the various growth period of the rice plant. The water budget of the irrigation and drainage as an integral is obtained from the unified management of the rainfall, irrigation water applied, soil water and ground water that takes part in the hydraulic cycle.
