摘要
作物对水分胁迫的响应及水分利用效率的研究是节水农业的重要方面,为此,对水分胁迫下作物形态、生理生化响应,作物水分利用效率的内涵、测定计算方法及提高作物水分利用效率途径等国内外的相关研究进行了回顾,并在此基础上,提出了我国目前在该领域研究和应用中存在的问题。
Researches on responses of crops to water stress and water use efficiency are both important aspects for Water-Saving agriculture. This paper presents a review of the studies on responses of crops morphology and physiological chemistry under water stress, introduces the connotation and calculating methods of crop water use efficiency, and discusses the approach of improving WUE. Based on the above work, problems still existing in the research and application of the domain in China are presented.
