Each has a double structure, and the inner plate is connected to the receiving portion 1c of the seedling.
And a water supply section 2 between the receiving section 1c and the outer claws 1a and 1b.
It is what constituted .

[0006]

The operation of the present invention configured as described above will be described. When the transplanted nail is lowered onto the ridge, the multi-hole opening heater attached to the outside of the transplanted nail opens holes for transplantation in the multi-film laid on the ridge, and at the same time, the seedlings in the transplanted nail are removed. It is implanted in the hole.

Further, while the pot seedling is in the transplanting nail, the heat of the transplanting hole opening heater is cooled by the water supply section provided between the transplanting nail and the receiving section, and the seedling is damaged by the heat of the heater. It is preventing.
