摘要
在农业生产中,水分和肥料是不可或缺的两大基本要素。水肥耦合将水、肥有机结合,通过二者的协同效应实现作物高产优质目的。在分析水资源紧缺和肥料施用不合理的现状基础上,回顾了水肥耦合的发展历程、定义及水肥耦合灌溉模式,阐述了水肥耦合对茄子生长形态、光合特性、产量和品质等影响的研究进展。结果表明,水肥耦合是节约水肥资源,降低环境污染,实现茄子高效优质增产的有效措施。深入探究茄子水肥耦合机制,构建多因素水肥耦合模型,寻求最佳水肥配比实现精准化灌溉,可为指导茄子合理的水肥管理并使茄子达到高效优质生长提供参考。
In agricultural production,water and fertilizer are two essential elements.Water and fertilizer coupling organically com-bines water and fertilizer,and achieves goal of high yield and high quality of crops through their synergistic effect.Based on analysis of current situation of water resources shortage and unreasonable fertilizer application,development process,definition and irrigation mode of water and fertilizer coupling were reviewed,and research progress of effects of water and fertilizer coupling on eggplant growth mor-phology,photosynthetic characteristics,yield and quality were elaborated,which indicated that water and fertilizer coupling was an ef-fective measure to save water and fertilizer resources,reduce environmental pollution,and achieve high-efficiency and high-quality yield of eggplant.Exploring coupling mechanism of water and fertilizer for eggplant,constructing a multi-factor coupling model of wa-ter and fertilizer,and seeking the best ratio of water and fertilizer to achieve precise irrigation could provide reference for guiding rational management of water and fertilizer for eggplant and making it grow efficiently and with high quality.
