Landscape greening floating bed and application thereof

The invention relates to a landscape greening floating bed and application thereof. The landscape greening floating bed comprises an outer frame (1) and a floating supporting substrate (2), wherein the periphery and the bottom of the outer frame (1) are provided with a plurality of air and water permeable holes; the floating supporting substrate (2) is provided with holes for planting plants; thefloating supporting substrate (2) is arranged on a boss of the outer frame (1); matrixes (5) are arranged in a space between the floating supporting substrate (2) and the outer frame (1); and the floating supporting substrate (2) and the outer frame (1) are fixed by an inserted plate (3) and an inserted bar (4). The application of the landscape greening floating bed comprises that: the inserted plate (3) and the inserted bar (4) can be used to connect the landscape greening floating bed with at least one other floating bed, and also can be used to connect the landscape greening floating bed with a fishing net (6); and various hydroponics flowers, ornamental aquatic plants, economic crops and the like which have high additional value can be planted on the floating supporting substrate (2).The landscape greening floating bed has the advantages of low cost, simpleness and convenience, corrosion prevention and ageing resistance, can be used repeatedly, has long service life, and not onlyincreases landscapes of water surface, but also contributes to improving eutrophication trend of aquaculture water to form a benign ecological system.
