作物非充分灌溉研究进展

Research Progress on Crop Deficit Irrigation

阐述了作物水分生产函数的一些基本原理和典型模型,并对其在非充分灌溉方面应用的状况以及国内外相关研究进展加以阐述。对作物灌溉制度优化模型以及优化灌溉制度设计方法加以探讨,为合理利用有限的水资源,达到作物最大的产量或产值,实现有限水量在作物生长期及作物间的合理配置提供依据。

The basic principles and some representative models of crop water production functions （CWPFs） were discussed,the advantages and disadvantages of deficit irrigation were introduced,along with its research progress in China and worldwide. The optimization model and design methodology were discussed which can provide some foundations for reasonably utilizing water resources in order to reach the maximum crop production or economic value during the growth period.
