摘要
综述了调亏灌溉方式对小麦产量和水分利用率的影响,从生理生态角度阐述了调亏灌溉增加小麦产量的机理,并从叶片水平、群体水平和大田水平论述了调亏灌溉的节水机理,分析了影响调亏灌溉效果的主要因素,如灌溉时期、调亏程度和其他农艺措施等,探讨了小麦调亏灌溉研究中存在的问题,并对小麦调亏灌溉理论与技术的应用前景进行了展望。
The effect of regulated deficit irrigation（RDI） on wheat grain yield and water use efficiency was introduced.The mechanism of RDI to increase the wheat output was expounded based on the eco-physiology.The reason of RDI to save water was explained from the leaf level,population level and field level.The main influencing factors,such as irrigating time,regulated deficit extent and other cultivation techniques,were analyzed.The problems present in the study of RDI was discussed.The status of the theory and technique of RDI for wheat was looked forward.
