China is one of coffee-producing areas in Asia and the yield of coffee in Yunnan province occupies 98% of China. Arabica coffee in Yunnan has special quality character of mellow but not bitter, fragrant but not strong and slight fruit acid taste. Shade cultivation and water-saving irrigation are two important factors affecting the growth of coffee, while there are randomness and blindness in the shade cultivation and irrigation of Arabica coffee in dry-hot valley of Yunnan Province. In this paper, the research progresses in the effects of water-saving irrigation and shade cultivation on the physiology ecology, yield and quality of Arabica coffee are discussed. Finally, several scientific problems need to be urgently studied: the physiological and ecological response mechanism, the quantitative relationship between physiology ecology and canopy micro environment, water consumption law, efficient use of water and quality and high yield mechanism as well as the coupling models of irrigation and shade cultivation of Arabica coffee under different irrigation and shade cultivation strategies.
