To exhibit an original function of a coating sheet such as weed-proof and properly generate a growth environment of plants.SOLUTION: A coating sheet 11 which is formed into a sheet shape by weaving warps and wefts in a dense state with shading property, and which comprises a coarse part formed by skip stitch of warps and wefts on a plurality of positions and with water permeability and ventilation property, covers a ground surface 13 in a house 12. Coating of the coating sheet 11 is performed on a top face of ridges 13a in which roots of plants are included, and water is sprayed to the coating sheet 11 from a water spray pipe 15 for water spray which is laid on the coating sheet 11.SELECTED DRAWING: Figure 1【課題】防草など被覆シートの本来の機能を発揮させつつ、植物の生育環境の適正化を行う。【解決手段】経糸と緯糸を緻密に織って遮光性を有するシート状に形成されるとともに、複数個所に経糸及び緯糸の目を飛ばして形成され通水性及び通気性を有する粗目部を備えた被覆シート11でハウス12内の地面13を覆う。被覆シート11の被覆は、植物の株元を含めた畝13aの上面に行い、その被覆シート11の上に敷設した散水のための散水管15から、被覆シート11の上に散水する。【選択図】図1
