摘要:
A seedling growing and handling device is provided and includes a tray-like structure consisting of a continuous sheet of material formed into a multiplicity of seed growth zones; each of the zones comprising a single confining wall defined by a hollow open ended truncated cone; and a web of the material of the sheet joining the lower larger diameter ends thereof into a continuous structure such that seedlings grown in the zone may be readily removed from the lower larger diameter ends with a minimum disturbance of the plants. The invention also contemplates the automatic transplanting of the seedlings from the device.
