Although coconut dust alone can be molded, it softens due to water absorption and swelling, so that it sinks deeply when stepping pressure is applied, making it unsuitable as a base material such as lawn. On the other hand, only the coconut peel small pieces are hard to be easily deformed by stepping pressure, but the molding itself is difficult. However, as described above, when coco dust and coconut peel pieces are mixed and compression-molded, the coco dust can act as a binder, so that a compact can be easily obtained. The substrate for plant growth of the first invention using this compression-molded product has high strength against stepping pressure on the substrate for plant growth and excellent air permeability due to the mutually supporting interaction of a plurality of small pieces of coconut peel. I have. In addition, the coconut dust has excellent water retention ability due to water absorption and water retention.

Can be. When a coconut fiber net or the like is used as the coating, the coconut fiber itself absorbs water when the base material for plant growth (excluding the coating) absorbs and swells, and the fiber is gradually loosened and stretched. This is preferable because the initial shape of the plant growth substrate main body can be maintained as it is. In addition, this coated body is on the surface side (top surface side) where plants germinate and elongate during construction
By roughening the mesh (hole) of the seedling and making it so large that germination and elongation are possible, the contact between the seedlings and seeds and the body of the plant growth base material is improved, which can have a positive effect on the growth of the plant. it can.
