Vegetation sheet

A vegetation sheet comprising:

• a main body having a surface layer in which Sunagoke grown seedlings are laid and a core layer which allows rhizoids of the Sunagoke grown seedlings extending with growth to enter therein;
• and
• a non-adhesive retaining member disposed in contact with a lower surface of the core layer of the main body, wherein
• the core layer has a netlike structure therein having spaces of an aperture size equal to or larger than the thickness of each rhizoid to allow the rhizoids to enter therein, wherein the spaces of the core layer communicate between the upper and lower surfaces so that the rhizoids entering the spaces project from the lower surface of the core layer, and wherein ends of the rhizoids projecting from the lower surface of the core layer are guided to extend and held between the core layer and the retaining member in the non-adhesive state.
