Filled soil block for cultivation, plant cultivation method, and soil block-cultivated plant

A filled soil block for cultivation in which a work hole in opened in an upper surface of a block body formed by compressively molding soil for cultivation, and in which soil for cultivation is filled in work hole. The block body is compressively molded and solidified to a hardness in which deformation is unlikely to occur, the work hole is unlikely to be blocked, and the shape can be self-held. The work hole has a size and depth that facilitates seeding, transplanting, cutting and planting, and other planting work. Filled cultivation soil and the block body have a soil quality and quantity that allow planting work in filled cultivation soil and that allow a cultivated plant to be grown to any stage of growth. Nutrients may be included as required. The soil-filled soil block for cultivation may be a monolithic shape, an integrated shape, or a divided integrated shape.
