| Abstract: | Under the treatment of regulated deficit irrigation during corn seedling stage, lower transpiration and higher water use efficiency(WUE) can be obtained. On the combination of adequate fertilization and rational close planting, higher yield and WUE can be gained. Two mathematical models were established based on the results of experiment and simulation. Various optimal schemes for two objectives were worked out. |

| Keywords: | regulated deficit irrigation(RDI) water saving mathematical model optimized scheme |
