When the bottoms 6 are substantially closed, and the partial bottoms of this deformed shape are formed, the degree of contact with each other is weakened when the partial bottoms are bent during the expansion, and the bottoms 6 are formed. Has the advantage of being easier.

[0021]

[Effects of the Invention] When plants are raised and transplanted using the bottomed pots of the present invention, the pots found when using pots made of conventional open-ended, open-ended paper or a thin film like paper are used. The phenomenon of soil escape from the body is completely eliminated, and it is possible to perform good work regardless of soil conditions, and the formation of the bottom part is the polymerization of the first, second and third partial bottoms. Therefore, even if transplanted with the pots attached after raising the seedlings, the roots of the seedlings easily grow out of the pots through the polymerization gaps in the bottoms of these parts that were embrittled in the soil due to the transplantation. It does not cause any hindrance, is highly practical, and can be used for raising and transplanting plants to make a great contribution to farming.
