PROBLEM TO BE SOLVED: To provide a base for aquatic plant planting, facilitating planting of aquatic plants which can promote greening in a river, a lake or the like, and excellent in water quality purification and environment, and to provide an aquatic plant base for underwater fixation, useful for greening and water quality purification, environmentally excellent and easy to construct.SOLUTION: This base for aquatic plant planting of a mat-like shape contains a wood crushed product, an iron-containing ceramics porous body, and an adhesive. The content ratio of the iron-containing ceramics porous body is a ratio to be a specific gravity allowing the base to sink in water. The aquatic plant base for underwater fixation is obtained by planting aquatic plants or their seedlings on the base for aquatic plant planting, and is usable by placing on the bottom of a river and a lake.COPYRIGHT: (C)2010,JPO&INPIT【課題】河川、湖沼等における緑化を推進しうる水生植物の植栽が容易であり、水質浄化に優れ、かつ環境的にも優れた水生植物植栽用基盤、並びに緑化並びに水質浄化に有用であり、かつ環境的にも優れ、その施工も容易な水中固定用水生植物基盤を提供すること。【解決手段】本発明の水生植物植栽用基盤は、木材破砕物と、鉄含有セラミックス多孔体と、接着剤とを含むマット状のものであって、鉄含有セラミックス多孔体の含有割合が、前記基盤が水中に沈降しうる特定の比重となる割合であることを特徴とし、本発明の水中固定用水性植物基盤は、上記水生植物植栽用基盤に、水生植物又はその苗木を植栽したものであって、河川、湖沼の底に載置して使用できる。【選択図】 図1
