摘要
水肥耦合可有效发挥水、肥协同效应,通过水分与养分间的最佳配比供给作物吸收同化利用,从而实现节水省肥、调质增产的目的。概述了水肥耦合的发展历程、定义及效应分类,分别阐述了水肥耦合在西瓜生长发育、生理特征、产量和品质等方面的相应研究进展,表明水肥耦合是西瓜高效优质生产的有效途径。深入研究探索西瓜水肥耦合机理,揭示农田系统水分和养分优化管理模式,可为指导西瓜水肥综合调控和节水节肥优质高产栽培提供理论依据。
Water and fertilizer coupling can effectively exert synergistic effect of water and fertilizer,and supply crops for absorption,assimilation and utilization through the best ratio of water and nutrients,so as to achieve purpose of saving water and fertilizer,adjusting quality and increasing production.Water and fertilizer coupling were summarized from development process,definition and effect classification.Then research progress of watermelon growth and development,physiological characteristics,yield and quality in response to the technology were separately described,indicating that coupling of water and fertilizer was an effective way to produce watermelon with high efficiency and high quality.Therefore,through in-depth research and exploration of water and fertilizer coupling mechanism of watermelon to reveal optimal management mode of water and nutrient in farmland system,which could provide a theoretical basis for guiding comprehensive regulation of water and fertilizer,as well as water-saving,fertilizer-saving,high-quality and high-yielding cultivation of watermelon.
