作物调亏灌溉理论与技术研究进展

Research Advance in the Theory and Technology of Crop Regulated Deficit Irrigation

介绍了作物调亏灌溉的概念,并从节水机理、增产机理两个方面来说明其生物学基础;从调亏灌溉的时间、程度、灌溉方式、施肥状况4个方面论述了调亏灌溉效应影响因素的研究状况;分析了调亏灌溉研究中存在的问题;对作物调亏灌溉理论与技术的发展趋势进行了展望。

Up to now,the regulated deficit irrigation（TDI） has been studied thoroughly and many excellent achievements have been accomplished.In the paper,the concept of regulated deficit irrigation was briefly presented.In the article the accent which owes the irrigation physiological mechanism and the production increase mechanism was introduced and the irrigation influence factors such as RDI degree,RDItime,fertilization,irrigated mode and so on were analyzed.The problems existing in the research on the regulated deficit irrigation were discussed as well.At the end,the development trend of the theory and technology of regulated deficit irrigation were prospected.
