ABSTRACT:
The present invention relates to a method wherein seedlings, raised in a paper tube assembly connected together by means of connecting portions having a separating line forming the separation course in each, are continuously pulled out while separating the tubes one by one and planting them in the field. In the separation of seedling tubes, a transplanter is provided with rollers for pulling out continuous seedling tubes and other rollers for separating the pulled out seedling tubes into individual seedling tubes. The latter has a faster rotating speed than that of the former and has a cone-like shape or is mounted so as to incline with respect to the former, thereby separating paper tubes into individual pot bodies at the connecting portions, one by one, while moving the separation acting points progressively. The separating-line in each connecting portion has an unjoined separation-guiding-portion extending from one end to 20-70% of the height of the connecting portion. Joined and unjoined portions are distributed over the remainder of the height.
