a movement robot for moving on a path in the cargo transport container; seedling growing tray racks including a multi-shelf germination rack for holding, until germination, a seedling growing tray on which seeds are sown, a multi-shelf seedling growing rack for holding a seedling growing tray on which seedlings have germinated, and a multi-shelf shipment rack for holding a seedling growing tray for shipping grown seedlings; and an arm or table provided to the movement robot and capable of transferring each seedling growing tray between the movement robot and each of the multi-shelf germination rack, multi-shelf seedling growing rack, and the multi-shelf shipment rack. ## Claims ### Claim 1 A seedling growing system comprising: a) a storage provided with heat insulating treatment; b) a movement means configured to move on a predetermined path in the storage; c) seedling growing tray racks including: a multi-shelf germination rack configured to hold, until germination, a seedling growing tray on which seeds are sown, a multi-shelf seedling growing rack configured to hold a seedling growing tray on which seedlings have germinated, and a multi-shelf shipment rack configured to hold a seedling growing tray for shipping grown seedlings, the multi-shelf germination rack, the multi-shelf seedling growing rack, and the multi-shelf shipment rack being disposed side by side on a side or sides of the path in the storage; and d) a transfer means provided to the movement means, including: a holding unit; a pinion gear capable of meshing with steps on a bottom of the seedling growing tray and provided at a leading end of the holding unit; and an auxiliary movement means comprising an arm including, at a leading tip thereof, steps capable of meshing with the steps on the bottom of the seedling growing tray, the auxiliary movement means being configured to move the leading tip from below a position where the seedling growing tray is placed on the multi-shelf germination rack, the multi-shelf seedling growing rack, or the multi-shelf shipment rack toward the holding unit and from the holding unit toward below the position, wherein the steps on the bottom of the seedling growing tray are aligned in a movement direction of the leading tip. ### Claim 2 (depends on 1) The seedling growing system according to claim 1, further comprising an environment control means configured to control an environmental factor in the storage in accordance with a plant being grown. ### Claim 3 (depends on 1) The seedling growing system according to claim 1, wherein the multi-shelf shipment rack is placed closer to a door of the storage than the multi-shelf germination rack and the multi-shelf seedling growing rack. ### Claim 4 (depends on 1) The seedling growing system according to claim 1, wherein the path is placed to a center in the storage to extend inward from a door of the storage, and the seedling growing tray racks are arranged on both sides of the path. ### Claim 5 (depends on 1) The seedling growing system according to claim 1, wherein the storage is a cargo transport container. ### Claim 6 (depends on 1) The seedling growing system according to claim 1, wherein the seedling growing tray racks include shelves having different pitches between the seedling growing tray racks. ### Claim 7 (depends on 6) The seedling growing system according to claim 6, wherein the seedling growing tray racks each include a plurality of shelves having different pitches between the shelves. ### Claim 8 A seedling growing system comprising: a) a storage provided with heat insulating treatment; b) a movement means including a mounting part for mounting a seedling growing tray and configured to move on a predetermined path in the storage; c) seedling growing tray racks including: a multi-shelf germination rack configured to hold, until germination, a seedling growing tray on which seeds are sown, a multi-shelf seedling growing rack configured to hold a seedling growing tray on which seedlings have germinated, and a multi-shelf shipment rack configured to hold a seedling growing tray for shipping grown seedlings, the multi-shelf germination rack, the multi-shelf seedling growing rack, and the multi-shelf shipment rack being disposed side by side on a side or sides of the path in the storage; and d) a transfer means provided to the movement means, including: d-1) an arm including a leading tip that is movable from below a position where a seedling growing tray is placed on one of the seedling growing tray racks toward the mounting part; and d-2) steps fixed to the leading tip and capable of meshing with steps on a bottom of a seedling growing tray, the steps on the bottom of the seedling growing tray being aligned in a movement direction of the arm when the seedling growing tray is placed on one of the seedling growing tray racks, the transfer means being configured to transfer each seedling growing tray between the mounting part and each of the multi-shelf germination rack, the multi-shelf seedling growing rack, and the multi-shelf shipment rack.
