ABSTRACT:
Plant seedlings are transplanted from a germination tray to one or more maturation trays by penetrating the soil plug surrounding the plant and its root system in the seedling tray by means of a rotating spirally coiled shaft, withdrawing the seedling, soil plug and shaft as a unit from the germination tray, inserting the plant, soil plug and shaft unit into the maturation container, and penetrating the soil plug with a needle-like holding implement while rotating the coiled shaft in a reverse direction to withdraw the shaft from the plug and deposit the plug and plant within the maturation container. In the preferred embodiment, a plurality of such coiled shafts are provided on a traveling frame controlled by a microprocessor to enable mass transplantation of plural seedlings to be carried out on a rapid automated basis.
