Next, the structure of the preliminary seedling storage device (A) will be explained.

The preliminary seedling storage device (A) is equipped with two upper and lower preliminary seedling loading stands (8), (8) for placing and storing large block-shaped seedlings (-) corresponding to the planting rows. , Seedlings (-)
The structure is such that the slides can be transferred in rows. To be more specific, as shown in Fig. 2, each of the preliminary seedling stands (8), (8) has a pair of front and rear support rails (9a), (9b) spaced apart appropriately, so that the support rails (9a), (9b) are oriented horizontally in a side view. They are connected by a letter-shaped connecting frame (10), and the seedlings (-) placed on the seedling scooping board (11) can be slid together with the seedling scooping board (11). The front side support rail (9a) is formed into a cross-sectional shape to receive and support the locking part (lla) of the seedling scooping plate (11), and
The rear side support rail (9b) has an arcuate upper surface and is configured to support the seedling (-) in a slightly upwardly rearward state.

In addition, this preliminary seedling stand (8) is 8 as shown in Figure 4.
It is long enough to form a gap of about 30 CI in the center when the seedlings (-) in the row are placed and stored, and the driver can plant the seedlings through the gap during the planting operation. The planting using the attachment device (2) is done in such a way that the situation can be visually observed.
