摘    要:通过对国内外分根区交替灌溉研究成果分析,综述了一种既能满足果树水分需求,又能控制植株长势、减少“奢侈”蒸腾、改善果实品质的果园节水灌溉新技术——果树根系分区交替灌溉,阐明了其理论体系和节水优产机理,概述了与该技术有关的部分根区干燥技术研究现状和存在的问题,提出了几种适合在果园应用的根系分区交替灌溉技术实施模式并对其可行性进行了探讨。分析了果树根系分区交替灌溉技术的应用前景和需要进一步研究的问题。

关 键 词:果树    根系分区交替灌溉    部分根区干燥    节水机理

Abstract:After having investigated references and research data at home and abroad, this paper introduced a new water-saving technique in orchard, which offered water requirement, improved fruit quality, simultaneously controlled vigour and decreased "luxury" transpiration of fruit tree, i.e., alternate partial rootzone irrigation(APRI). Its theory system, water-saving mechanism and difference with regulated deficit irrigation(RDI) were summarized, research status and problems of the related partial rootzone irrigation(PRD) were also discussed. Some application patterns of APRI in orchard were put forward and their feasibilities and applicabilities were analyzed, then the application prospects and problems of this new irrigation technique were reviewed.
Keywords:fruit tree  alternate partial rootzone irrigation  partial rootzone drying  water-saving mechanism
