  • Planting device for planting a seedling-growing tape in the field
    Patent number: 6595149
    Abstract: A seedling-growing sheet (1) is in the form of a laminate body (2) consisting of a band-like support member (3) and a porous sheet body (4) laminated on the support member (3). A large number of receptacles (6) for housing rice seeds (15) are formed in the sheet body (4) of the laminate body (2). These receptacles (6) are arranged apart from each other in the longitudinal direction of the support member (3). Formed in the laminate body (2) are cutting perforations (8) consisting of a large number of cut lines (9) along which planting pieces (10) each having at least one receptacle (6) are cut away from the laminate body (2). These cutting perforations (8) are arranged apart from each other in the longitudinal direction of the laminate body (2).

  • Seedling raising sheet, method of manufacturing same, seedling raising method, culturing method, and transplanter
    Patent number: 6240674
    Abstract: A seed top of foamed cells is constructed such that a porous sheet having open cells is affixed to one surface of a thin support band extending in a band-like configuration with its widthwise direction being an up-and-down direction, and accommodation recesses for accommodating seedling seeds are provided in the porous sheet. It is possible to reduce the size and weight of the seedling raising sheet used for raising seedlings and to eliminate the need for soil in raising seedling, thereby enabling an industrial mass-production of the seedling raising sheet.
