肥水耦合研究一直是节水技术和合理施肥研究的一个重要方面。从根系分区施肥技术、肥水耦合对植物根系影响及其作用机理、局部施有机肥与肥水耦合结合对植物叶片光合特性的影响等方面综述了肥水耦合相关研究。

The research of water-fertilizer coupling is always an import part of water-saving technology and rational fertilization. This paper aim to describe the current situation of water-fertilizer coupling by the analysis of partition fertilization， the influences and mechanism of action that the water-fertilizer coupling， partition fertilization effected on the root of plant， and the photosynthetic characters of leaves effected by the partition organic-fertilization. Meanwhile， this paper looks forward to the future of apple trees partition organic-fertilization.
