| 摘 要： | 根据霍泉灌区田间试验资料,考虑水分亏缺的后效性,以冠层叶面积指数修正后的作物-水模型作为目标函数,建立二雏动态规划模型,计算冬小麦节水高效优化灌溉制度。结果显示,该模型充分反映了灌水时间、灌水定额和灌溉水量产生的冬小麦的产量效应,所建模型和参数确定较合理,在实践中更有实用性。

| Abstract: | Two-dimension dynamic programming model was established based on the model of crop responses to water modified by introducing of crop canopy leaf area index with consideration of the after-effect of water deficit. Optimal irrigation scheduling of winter wheat was obtained according to the experimental data in Huo Quan Irrigation Area. The simulated results indicated that the model could well reflect the effects of irrigation time,each irrigating amount and total irrigation amount on winter wheat yieldsl, which showed the model and the parameters were reasonable and practical. |
