In the state shown in FIG. 3B, when the seedling planting device A is set at the lowest position with respect to the traveling machine together with the link mechanism (not shown), the seedling placing surface b, the fertilizer storage hopper 8, and the feeding mechanism The interval between the seedling 9 and the seedling 9 is greatly widened, so that the seedling remaining on the seedling placing surface b can be easily treated.

[Another Embodiment] Not only the fertilizer storage hopper 8 and the feeding mechanism 9 but also the downflow pipe 10 and the groove generator 11 are integrally formed.
The fertilizer applicator B may be configured to move in the vertical direction as a whole. As a mode of moving the fertilizer applicator B in the vertical direction, a link (not shown) may be used instead of the guide column 12. As a mode of providing the stand 23, only when the stand 23 is attached to the storage portion of the riding type traveling body and the operation of moving the fertilizer applicator B to the upper non-working position is fixed, the stand 23 is removed from the storage portion. It may be configured to be detached and used by inserting the stand 23 between the bracket 24 and the ground. In this case, the stand 23 may be of a fixed size instead of a telescopic type. The mechanism for moving the fertilizer applicator B in the up-down direction may be configured to automatically move the fertilizer applicator B using an actuator (not shown) such as a hydraulic cylinder. A configuration in which the feeding mechanism 9 is driven by a dedicated motor (not shown) may be adopted. When this motor is attached to the feeding mechanism 9, a separation device such as a turnbuckle-type connecting tool 22 is not required. As the fertilizer applicator B, besides the side-strip type fertilizer applicator B shown, a deep-layer type fertilizer applicator B and a side-strip deep-layer fertilizer applicator B, or a fertilizer applicator B and a fertilizer spraying apparatus may be arranged in parallel. The stand 23 may be extended by air pressure and contracted when the air pressure is released. In this case, a configuration may be adopted in which a foot-operated air pump is used as the air pressure supply means, and the plug is loosened to release the air pressure. The fertilizer applicator B may be located on the back side of the seedling rest 1. The present invention may be applied to a walking type rice transplanter equipped with the fertilizer application device B.
