Then, the granule R is guided to the guide plate 9 by the guide plate 8, and the granule R on the guide plate 9 is guided toward the horizontal axis supply roll 11 and is fitted into the supply recess 12 of the horizontal axis supply roll 11. .

The granule R fitted in the feeding recess 12 of the horizontal axis feeding roll 11 rotates together with the rotation of the horizontal axis feeding roll 11, and the extra granule R not fitted in the feeding recess 12 by the rotating brush 13 is fed out by the horizontal axis. The granule R swept back to the roll 11 side and fitted in the feeding recess 12 further rotates together with the horizontal axis feeding roll 11.
Since the chute 16 is provided on the rotation descending side of the horizontal axis feeding roll 11, the granule R fitted in the feeding concave part 12 is released from the feeding concave part 12 under the action of the centrifugal force of the horizontal axis feeding roll 11. It is tricked into shoot 16.

  In this case, the seedling pot P is placed in an even number on the tray T, transferred so that the joint 23 at the edge of the seedling pot P is located in the center, and the shoots 16 are arranged on both the left and right sides of the joint 23. Since the outer shoots 16 are arranged outside the center pair of shoots 16 at a predetermined interval, even if the breeding pots P having different sizes are transferred, the shoots 16 are not separated from each seedling pot P. The granule R is supplied in a strip shape at a predetermined position removed from the center of.

That is, the seedling pot P is evenly placed on the tray T, and the seam 23 of the edge of the seedling pot P is always positioned at the center of the left and right of the tray T.
Next, the center position of the pair of chutes 16 in the center is adjusted so that the intermediate position is positioned above the eye 23.
Next, what is necessary is just to align the position of the outer chute | shoot 16 with respect to this center pair of chute | shoot 16 to the predetermined position in the edge of the outer seedling pot P. FIG.

  With reference to the pair of chutes 16 in the center, the chutes 16 may be positioned outside and above the inside of the edge of the seedling pot P. Once the positions of the pair of chutes 16 in the center are set in advance, Even when the size of the seedling pot P placed on the tray T is changed, the pair of chutes 16 in the center are located above the seedling pot P, the granules R are dropped, and the seedling pot P and the chutes in the center are dropped. 16, and the position of the pair of outer chutes 16 may be adjusted with reference to the pair of chutes 16 at the center, thereby facilitating the adjustment.

Accordingly, since a predetermined amount of the shoot 16 is supplied to a position avoiding the seedling to be transplanted in the center of the seedling pot P, the growth of the transplanted seedling is not hindered by the effect of fertilizers or chemicals. Can be evenly grown and provide good seedlings.
In this case, the feeding concave portion 12 of the horizontal axis feeding roll 11 is formed to be long in the direction of the generatrix and is configured to fit a predetermined amount of the granule R, and the guide portion of the chute 16 is arranged in the lateral width of the feeding concave portion 12. Since the attachment portion 17 is set to a width obtained by adding the movement amount of 18, even if the chute 16 is moved in the left-right direction according to the seedling pot P, the attachment portion 17 of the chute 16 drops from the feeding recess 12. Ensure that agent R is received.
