【摘要】 水稻（Oryza sativa L.）是世界主粮作物之一，同时也是农业第一用水大户。农业灌溉用水的日益短缺严重制约着水稻生产的可持续发展。目前，大部分水稻节水灌溉技术或体系的一个共同特点是稻田要多次经历由水层到适度干旱，再到复水的循环过程。有关水稻植株从土壤适度干旱状态到复水状态转变过程中的响应机制缺乏系统总结。本文系统综述了水稻的主要节水灌溉技术、水稻响应干旱复水过程中的品种间差异、地上部农艺和生理特征、根系形态和生理特征及水稻对干旱复水响应的分子机制等方面的研究进展，提出了目前的挑战和未来的研究趋势，旨在为选育高产节水水稻品种和高效节水栽培技术提供参考。更多还原

【Abstract】 Rice(Oryza sativa L.) is one of the main grain crops in the world, and the largest water user in agriculture. The increasing shortage of agricultural irrigation water seriously restricts the sustainable development of rice production. One common feature of most water-saving irrigation technologies or systems of rice is that rice fields have to experience the cycle process from water layer to moderate drought and then to rehydration. The response mechanism of rice plants during the transition from moderate drought state to is not systematically summarized. This paper systematically reviews the research progress of the main water-saving irrigation techniques, the differences among varieties in the process of rice response to drought rehydration, the aboveground agronomic and physiological characteristics, root morphology and physiological characteristics, and the molecular mechanism of rice response to drought rehydration, proposes the current challenges and future research trends, the aim is to provide reference for breeding high-yield water-saving rice varieties and efficient water-saving cultivation techniques.更多还原
