| Abstract: | Based on different water deficit treatments, water sensitivity indexes for spring wheat were established. The means and steps of accomplishing optimum distribution of limited water during crop development stage using dynamic programming were introduced. Then taking spring wheat in western Liaoning province for example, the optimum distribution decision of dynamic programming model was made under the conditions of available irrigation water during different development stage. |
| Keywords: | spring wheat water sensitivity index Jensen model dynamic programming |
