Planting structure for greening and structure for floating island using the same

摘要

PROBLEM TO BE SOLVED: To provide a plant structure and a structure for a floating waterweed which are light (weather) resistant and capable of firmly fixing aquatic plants during use but causing photodegrading decomposition and natural decomposition to readily decompose the plants and supports and easily carrying out recycling or disposal of the plant supports after the use. SOLUTION: This plant structure for greening is obtained by using a three- dimensional netlike structure made of a thermoplastic resin having =90% porosity, 20-100 kg/m3 apparent density and 30-100 mm thickness as the plant supports, vegetating plants having rootlets near the surface layer of the plant supports and making the aquatic plants for greening symbiotic. The structure for the floating waterweed uses the structure for the greening.
