Abstract With the improvement of people's living standard and the maturity of modern agriculture theory, winter wheat production tends to put more emphasis on grain quality and yield, and pay more attention to the efficient use of water and nitrogen. Winter wheat yield and quality is not only influenced by genetic traits, but also affected by cultivation measures and environmental factors. Among them, water is one of the most important factors. This paper reviewed the research progress of the response of winter wheat growth, photosynthetic product formation and distribution, and nitrogen and water absorption, etc. under regulated deficit irrigation. And focused on the status quo of effects of regulated deficit irrigation on winter wheat yield, quality, and water and nitrogen use efficiency worldwide. At the end, the developing trend in the future was briefly discussed. Keywords: Regulated Deficit Irrigation; Winter Wheat; Grain Quality

调亏灌溉对冬小麦产量、品质及 水氮利用影响的研究进展 * 刘晓菲,申孝军†,高阳,孟兆江,宋妮 中国农业科学院农田灌溉研究所 农业部作物需水与调控重点实验室,河南 新乡 453002 摘

要:随着人民生活水平的提高以及现代农业理论的日渐成熟,冬小麦生产趋于籽粒品质和产量并重,且更加重视水

氮的高效利用。冬小麦产量和品质不仅受遗传特性的影响,还受栽培措施及环境因素的影响,其中,水分是影响冬小麦 产量和品质的重要因素之一。该文综述了调亏灌溉条件下冬小麦生长、光合产物形成与分配以及水氮吸收等方面的研究 进展,重点阐述了调亏灌溉对冬小麦产量、品质以及水氮利用效率影响方面的现状,并对未来发展趋势做了简要讨论。 关键词:调亏灌溉;冬小麦;品质

引言 小麦是我国第二大粮食作物,种植面积在 3.5 亿亩左右,同时约有 50%的人口以小麦为主食。随着社会 经济的快速发展和人民生活水平的日益提高,冬小麦生产在重视食物数量的同时,更加注重品质和质量安 全。近年来,国内外众多学者从遗传育种、耕作栽培措施等方面系统研究了影响冬小麦产量和品质的因 素,大量研究表明,作物籽粒产量和品质的形成除受遗传基因控制外,更多的依赖于水分和养分等外界环 境因子[1~3]。因此可以通过改善农田生态环境,协调和改善根系对水肥的吸收和传输能力,控制和优化植物 *
