2. Description of the Related Art In this type of seedling planting apparatus, the seedling feeding belt is fed by friction, or a protrusion provided on the belt is bitten into a mat-shaped seedling or the like for feeding. If the roots of the seedlings are hard, the protrusions may not bite well. Further, in recent years, from the need to add a sufficient feeding action to the seedling take-out port, there are those that take a long stretch length of the seedling feeding belt, but in this case, the belt may hang under its own weight, On the contrary, sometimes the belt feeding was not enough. Therefore, the applicant of the present application proposed in Japanese Patent Application No. 3-3124 to provide a guide member for supporting the conveying surface of the seedling feeding belt from the back side and suppressing the slack of the belt.
