PROBLEM TO BE SOLVED: To obtain a mat or block for plant culturing, capable of improving resistance to environmental contamination, rooting property, growing property of root without discharging applied water and fertilizer by molding materials for mat with a binder not containing a surfactant. SOLUTION: Materials for mat are molded by using a binder (e.g. epoxy- based resin or urethane-based resin) such as a thermoplastic and thermosetting and room temperature-curable binder and/or solvent-solubilized binder, without containing a surfactant such as a surfactant having surface tension lowering by >=10 dyne cm<-1> in 0.1% aqueous solution or suspension at 20 deg.C. Furthermore, one or more materials selected from natural bark, peat-moss and mineral substance having short fiber-like or granular shape are preferably used as main materials for mat. |
