ている。 The culture bed of the present invention is a mixture of the artificial soil described above and the three-dimensionally crimped composite type synthetic fibers, or, if desired, other types of fiber materials or granular materials are added to these materials. A composite is obtained by dispersing the ingredients in an amount within a range that achieves the purpose of the present invention. Such a composite is formed into a desired shape by, for example, depositing and filling these materials into a mold surrounded by a mesh plate, etc., and then molding the material into a desired shape. It is obtained by softening the surface layer of three-dimensionally crimped composite synthetic fibers by placing them under hot air, etc., and then fusing them at mutual contact points. The composite of artificial soil and fibers etc. obtained in this way forms a three-dimensional network structure, and the particles of the artificial soil are held between the meshes of this network, and some of them are It has a structure in which it is fused and fixed with three-dimensionally crimped composite synthetic fibers.
