PROBLEM TO BE SOLVED: To provide a method for cultivating plants using pulp soil by which plants can be cultivated on everything in indoor greening in vegetable factories or the like, outdoor greening or the like utilizing pulp growth material having water retainability and air permeability, free from dispersion due to wind or the like and outflow due to rain or the like and also functioning as nutrients (fertilizer) for plants.SOLUTION: The method for cultivating plants comprises: mechanically and/or chemically treating botanical plant bodies (only fibrillating when using a pulp product such as waste paper) to take out cellulose fiber 2 which is a major component of cell walls and fibers produced via carbon dioxide assimilation and forming the plant body, in a form of simple substance, to be directly paved over asphalt, concrete, metal, net, stone, gravel, sand, soil, wood board, resin or rubber in the thickness of &ge50 mm to make pulp soil P (growth floor material made of pulp) function as a new source of nutrition for the plant body to cultivate the plant 5.COPYRIGHT: (C)2011,JPO&INPIT【課題】保水性と通気性がよいと共に、風等による飛散や雨等の水で流れ出ず、植物の養分(肥料)にもなるパルプ生育材で野菜工場などの屋内や屋外の緑化等において万物上に植物栽培することができるパルプ土壌による植物の栽培方法を提供する。【解決手段】草木の植物体を機械的または/或いは化学的に処理して(古紙等のパルプ製品の場合は解繊するのみ)、炭酸同化作用で生産されて植物体を構成している細胞壁および繊維の主要成分であるセルロース繊維2を単体で取出し、アスファルト、コンクリート、金属、網、石、砂利、砂、土、木板、樹脂、ゴムの上に50ミリ以上の厚さで直接敷き詰めて、新植物体の栄養源になって植物5が栽培できるパルプ土壌P(パルプ生育床材)とした。【選択図】図3
