Effects of Regulated Deficit Irrigation and Optimized Agronomic Measures of Corn

Under the treatment of regulated deficit irrigation during corn seedling stage, lower transpiration and higher water use efficiency(W_UE) can be obtained. On the combination of adequate fertilization and rational close planting, higher yield and W_UE 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.
