DEVICE FOR ASSISTING TRANSPLANTING OF SEEDLINGS, MACHINE INCORPORATING THE DEVICE, AND METHOD USING THE DEVICE

Seedlings are typically grown in trays of soil plugs. Once the seedlings hav e attained a predetermined size, they may be transplanted to the ground for continued seedling growth and development. Several machines are known in the art, which allow automated seedling transplantation. The present invention provides a device that significantly improves the accuracy of automated transplantation of seedlings. The device encompasses, at least in preferred aspects, a ski-like apparatus (12,13) including a defined planting slot (18) for receiving the seedlings to be planted. Furthermore, a blade (19) extendi ng in front of the device cuts open the ground in preparation for plantation. T he configuration of the device enables seedlings to be planted accurately to a desired planting depth. The device is particularly suited for use in connection with coniferous tree seedlings, and enables automated transplantation of such seedlings at high speed. The invention pertains to t he device, to machines adapted to incorporate the device, and also to methods o f seedling transplantation involving the device.
