摘要
作物———水模型的选择是制定节水灌溉制度的重要环节,也是实现水资源优化利用的主要依据。本文通过干旱区节水灌溉试验研究,介绍了干旱区作物———水模型的选择过程,并对原始模型进行了修正,从而为干旱区节水灌溉制度的制定提供了依据。
The selection of crop water models is an important step in making water saving systems. It is also the primary indicator in optimizing using of water resources. Based on the test of water saving irrigation systems in rainfed areas, this paper shows the selection process among crop water models and modifies original models. It therefore provides a base for making water saving irrigation systems in rainfed areas.
