摘要
根据相关文献,从农田水肥耦合的定义、水分及养分相互作用的机理、水肥耦合效应对作物生长的影响、水肥对作物产量的耦合效应、水肥耦合对水分利用率和肥料利用率的影响、水肥耦合对作物品质的影响等方面对农田水肥耦合机理与技术研究进行了综述。
Based on the relative literature,the definition of couple effect of water and fertilizer,the mechanism of water and fertilizer interactive effect,and from the water and fertilizer couple effect on crop development,yield,water and fertilizer use efficiency,and grain quality aspects,the theoretic and technological couple effect of water and fertilizer are reviewed in this article.
