Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising pot for raising seedlings such as vegetables.

[0002]

2. Description of the Related Art Known seedling raising pots of this type are known, for example, from Japanese Utility Model Laid-Open No. 1-19956 and Japanese Utility Model Registration No. 30202013. This conventional one has a cylindrical side wall terminating at an opening edge at an upper end side, and a bottom wall continuous with an axial lower end side of the side wall and having a drain hole, and the seedlings are grown by the side wall and the bottom wall. It is a seedling raising pot formed as a single pot, which divides a soil storage chamber, and is provided with a plurality of U-shaped ridges extending vertically in the side wall.

[0003]

In the prior art, since the cross-sectional shape of the ridge is a U-shape, when an empty seedling raising pot is to be stacked, the seedling raising seedling pot located below is raised. The cylindrical part of the upper seedling pot could not enter the soil storage room, and was bulky for storage, storage and transportation.

[0004] Further, in the conventional one, a large number of ridges are provided, so that the roots of the seedlings grow over the inner peripheral surface of the adjacent ridge without reaching the inner surface of the side wall, and the "root winding" is formed. It could not be effectively prevented. Therefore, an object of the present invention is to provide a seedling pot that can store an empty seedling pot without being bulky and that can effectively prevent root winding.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, the feature of the present invention is that in a seedling raising pot in which a side wall and a bottom wall form an upwardly open seedling raising chamber and a ridge extending vertically is provided on the side wall, the ridge has a cross section thereof. The shape is a V-shape, and a pair is provided opposite to each other via the center of the nursery room.

According to the present invention having the above-described structure, since the cross-sectional shape of the ridge is V-shaped, the upper seedling room is stored in the lower seedling room even if empty seedling pots are vertically stacked. It will not be bulky. In addition, since a pair of ridges are provided, the root surely grows along the inner surface of the side wall, and grows downward when it reaches the ridge, so that root winding is prevented.

In the present invention, the nursery room preferably has a rectangular cross section, and the ridge is preferably provided on a side of the rectangular shape. However, the ridge may be provided at the rectangular corner portion. Further, the seedling raising pot is mounted on a transplanter, the seedling extraction nail of the transplanter is configured to be removable from an opening of the nursery room, and the ridge is the seedling extraction nail. It is preferably provided at a position that serves as a guide when inserting and removing the.

However, when inserting the above-mentioned seedling removal nail, it may be provided at a position away from the removal nail.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a nursery tray 1
In the tray 1, a large number of seedling raising pots 2 are arranged vertically and horizontally at a predetermined pitch. FIG. 2 is a longitudinal sectional view of the seedling raising pot 2, and FIG. 3 is a transverse sectional view thereof.

The seedling raising pot 2 has a side wall 3 and a bottom wall 4 forming an upwardly opening seedling raising room 5, and a ridge 6 extending in the vertical direction (depth direction) on the side wall 3 is provided in the vertical direction. It is provided over substantially the entire length. The bottom wall 4 is provided with a hole 7 for drainage. The cross-sectional shape of the nursery room 5 is rectangular, and the rectangular corners are connected by an arc.
And the said protrusion 6 is provided in the said rectangular side part.

The ridge 6 has a V-shaped cross section, and a pair of ridges 6 are provided facing each other with the center of the nursery room 5 therebetween. The V-shape is such that when the seedling trays 1 are stacked one on top of the other, the projections 6 are fitted into the lower seedling room 5 so that the outer peripheral surface of the upper seedling raising pot 2 can be tightly fitted. It has a shape that can be done. Therefore, when the trays 1 are stacked, they are not bulky.

According to the above configuration, since the number of the ridges 6 is as small as two, the probability that the roots of the seedlings abut on the side wall 3 when growing will be extremely high. Then, it tends to extend in the circumferential direction along the side wall 3. And it grows further and comes into contact with the ridge 6 to be forced to change direction. At this time, the root is directed downward, and "root winding" is prevented. The seedling pot 2
Is mounted on a transplanter described in, for example, JP-A-9-74831 or the like, and a seedling removal nail of the transplanter is configured to be freely insertable / removable from an opening of the nursery room 5; The ridge 6 is provided at a position serving as a guide when inserting and removing the seedling removal nail. That is, it is provided at a position along the insertion / removal path of the seedling removal nail in sliding contact with the nail.

[0013] By using the projection 6 as a guide for the seedling removal nails, the movement locus of the nails can be stabilized, and the seedlings can be reliably extracted. FIG. 4 shows another embodiment of the present invention. A different point from the one shown in FIG. 1 is that the ridge 6 is provided at a corner of the rectangular seedling raising room 5. The other configuration is the same as that shown in FIG.

[0014] In this case, the projection 6 is provided at a position distant from the picking nail when the picking nail is inserted. The present invention is not limited to the above-described embodiments. For example, the seedling-growing pots may not be provided in a large number on the tray, but may be a single pot-shaped product. Is not limited to a rectangular shape but may be a circular shape.

[0015]

According to the present invention, an empty seedling-growing pot can be stored without being bulky, and root winding can be effectively prevented.
