A strips peeling off apparatus and a carrying conveyor are disposed on a body of a machine for transplanting seedlings. A series of pots is taken out from a multiple series of pots 1 placed on the body through a pair of guide plates by pulling two strips with a pair of taking-out rollers through the pair of guide members toward the front side of the body to expose the seedlings with soil exposed from the pots of the series of pots. The seedlings with soil are carried toward the rear end side at the same velocity as the velocity of the body by clamping the root block portion of the seedling with a first conveyor, and subsequently, with a second conveyor, by clamping the leaf portions of the seedlings to carry the seedlings toward the rear side of the body into a planting groove formed by an opener mounted below the body.

A continuous assemblage of pots for raising and transplanting seedlings and a method of manufacturing the assemblage is provided, in which it is possible to extend the length of a link piece without folding an extension portion or arranging a slit, thereby making it possible to handle enlargement of the interval between the planted seedlings stably and reliably. A link piece is formed by folding back both ends of a strip-shaped thin film in the length direction, such that approximately one-fourth of the length of the thin film is folded back onto the same face of the thin film at each end, then attaching the folded-back portions to the same face of the thin film with a water-soluble adhesive. The link pieces are disposed in two rows in a staggered arrangement in which the folded-back portions are oriented such that they face the folded-back portions of the opposing link pieces. Continuous pieces are formed by using a non-water-soluble adhesive to attach both ends in the length direction of each link piece to the opposing link pieces. Individual pots are formed between the opposing link pieces. Therefore, it is possible to extend the length of the link piece without folding an extension portion or arranging a slit, as in the conventional continuous assemblage of pots, thereby making it possible to handle enlargement of the interval between the planted seedlings stably and reliably.
