Heavy rain occurred frequently in South China during rice growth stages and pollutant from drainage water has caused serious environmental problems.The present controlled drainage methods pay much attention to storing more water in basins and reducing pollutant from basins, however, how to control runoff from basins, ditches, channels and other non cultivated areas are often ignored at present.Coordinated Controlled Drainage(CCD), with basin and ditch was proposed in the paper in order to reduce both runoff and pollutants from basins and ditches.Lower irrigation limit was used while rain water was stored in paddy basins as much as possible according to the waterlogging-tolerant and drought-tolerant ability of rice at first to reduce runoff and concentration of pollutant, surplus rain water from basins, as well as from non cultivated area were retained in ditches once again by a construction at the outlet.Field experiments found controlled drainage at field scale could reduce water consumption by 18% compared with the present model, irrigation and drainage quota declined 28.0% and 60.6%.Total nitrogen (TN) and total phosphorus (TP) loss reduced 58.6% and 58.8%,respectively at field scale.On ditch scale runoff, Tn and TP decreased 58.9%, 59.7% and 66.7%, respectively compared with uncontrolled ditch.TN and TP concentration of the water in basins and ditch at early stage after rainfall were higher and decreased fast with time,indicting that held water in basins and ditches at that time could remove TN and TN more efficiently from water.The experiment also found that runoff from non cultivated area accounted for 27% ~27.0% of the total runoff from ditches, suggested CCD was an effective method to reduce pollutant and runoff in paddy field in South China.
