Abstract:As a trend in the development of mosaiculture, prefabricated three-dimensional greening has great exploration value for its advantages of high efficiency, high quality and high standards. This article takes the "Concentric Circles" mosaiculture, the gold award of art garden of the 28th Guangzhou Garden Expo (enterprise exhibition garden) in 2021 as an example, which uses the prefabricated threedimensional greening form. Combined the literature review and the experience of actual participation, the article uses methods such as comparative analysis and inductive summary, to introduce the basic characteristics and advantages in plant application, construction method, process technology and maintenance management, and analyzes the problems and future improvement measures in design ideas, implementation technology, flower selection and application promotion.
