Abstract
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 3 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 in 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 3 are disposed in two rows in a staggered arrangement in which the folded-back portions 6 are oriented such that they face the folded-back portions 6 of the opposing link pieces 3. Continuous pieces 8 are formed by using a non-water-soluble adhesive to attach both ends in the length direction of each link piece 3 to the opposing link pieces 3. Individual pots 2 are formed between the opposing link pieces 3. Therefore, it is possible to extend the length of the link piece 3 witho…
