Description

  The present invention relates to a seedling container for growing plant seedlings such as vegetable seedlings, flower tree seedlings, tea tree seedlings, etc. until transplanted to a breeding place.

  Conventionally, when raising plant seedlings such as vegetable seedlings, flower tree seedlings, tea tree seedlings, etc., soft resin seedling containers called pots and corrosive seedling containers made of paper have been frequently used. In such a seedling container, when the root of a seedling that grows along with the growth of the plant hits the inner wall surface of the seedling container, it grows while rotating along the inner wall surface, and the roots are complicatedly entangled with each other. "Occurs. When root winding occurs, water accumulates in a complicatedly entangled part, causing root rot, or entangled roots being damaged each other, causing death due to entry of various bacteria into the root. In addition, the seedling that has caused the root winding has poor growth after being transplanted to the growing place. It is desirable that the roots of the seedlings grown in the seedling container extend straight.

  For these reasons, seedling containers that can prevent root winding have been demanded, and many seedling containers that have a plurality of protrusions extending in the vertical direction on the inner surface of the side wall have been proposed as means for preventing root winding. (For example, refer to Patent Documents 1, 2, and 3.)
