遗传算法在节水高效灌溉制度优化中的应用——以冬小麦为例

The Application of Genetic Algorithm in Efficient Irrigation Scheduling Optimization——Using Winter Wheat as Example

利用遗传算法对非充分灌溉条件下冬小麦的最优灌溉制度设计进行求解,并提出了与之对应的约束条件及处理方法。以我国华北地区某试验站为例来说明该算法及处理方法的可行性。结果表明,该方法能够实现对冬小麦整个生育期灌溉水量进行合理分配,使冬小麦在缺水敏感期内得到充分灌溉,从而达到节约灌溉用水,提高水分利用效率的目的。

Genetic algorithm was used in this paper to calculate the optimal irrigation scheduling of winter wheat under the condition of deficit irrigation, and then the corresponding constraint conditions and methods were put forward. The experiment station in north China was used as example to demonstrate the feasibility of this algorithm and method. The results shows that it can be used to distribution the irrigation water during the whole growth period of winter wheat. And the winter wheat can be irrigated sufficiendy in water sensitive period to save irrigation water and improve the efficiency of water.
