摘要
在农业水资源的日益紧缺下,为了减少水稻的灌溉用水和肥料高效利用以实现水稻稳产高产,综述了国内外水肥耦合的研究进展、水肥耦合的概念及其协同、拮抗、叠加三种效应,水肥耦合的机理、水肥耦合对水稻生长发育及产量品质的影响、水肥耦合对水稻中N素利用效率的影响;展望了中国目前在水肥耦合研究方面可以提升的空间,提出了水肥耦合模式是争取水稻高产优质的有效措施,以及如何根据实际需要,运用"以水促肥、以肥调水",建立合理的水肥耦合模式,提高水肥利用效率,在节约灌溉用水和不增加施肥量的前提下达到既保证作物优质高产又减少环境污染的双重效果,为今后节水农业及水稻的田间栽培和管理提供理论与技术依据。
With the growing shortage of water resources in agriculture, in order to reduce the rice irrigation water and fertilizer usage to achieve the rice stability and high yield, this report reviewed the research progress at home and abroad about the conception of coupling of water and fertilizer and its three effects： synergistic, antagonistic, superposition, as well as the mechanism of water and fertilizer coupling and the effects on rice growth, development, yield, quality of rice, and utilization rate of nitrogen. The paper also forecasted the improvement space in coupling of water and fertilizer and putted forward the coupling model of water and fertilizer, which are the effective measures for high yield and quality of rice, and how to apply the ＂water and fertilizer, water by fertilizer, water and fertilizer coupling mode＂ in practice to establish the reasonable mode to improve water use efficiency, save irrigation water without increasing the amount of fertilizer and ensure the double effect of high-yield crops while reduce environmental pollution, therefore to provide some theory and technology basis on water-saving agriculture and cultivation and management of rice.
