Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper nursery container used for growing paper pot seedlings for rice transplanters.

[0002]

2. Description of the Related Art The above paper nursery container is disclosed in, for example, JP-A-56
As disclosed in Japanese Patent Publication No. 144017, a large number of seedling-growing pots which are provided with openings for growing seedlings at the upper end and which are opened downward are integrally connected and are stored and loaded in a seedling-raising box. Used. This paper-made seedling raising container is formed by attaching melted paper fibers to a net-shaped male frame, as disclosed in, for example, JP-A-63-79540.

[0003]

Since this paper nursery container is made of paper fibers, it is difficult to obtain high dimensional accuracy, and the dimensions are likely to change due to expansion and contraction due to moisture absorption. In addition, the size of the nursery box itself was not uniform, so that when it was stored and loaded in the nursery box, it sometimes moved internally. The seedling raising box used here has a standard specification used for growing mat-like seedlings, and its inner dimension is about 30 × 60 cm. If the paper-made seedling raising container is integrally molded to such a size, it becomes difficult to remove the mold, or the deformation such as warpage becomes large. Therefore, as shown in Japanese Patent Laid-Open No. 1-277429, in reality, two containers are used. Paper nursery containers are used side by side in the longitudinal direction of the nursery box.
In this case, each paper-made seedling container has a substantially square shape, but the number of rows of seedling-raising pots may differ by about one row between the front and rear and right and left. In this case, two paper-made seedling containers are aligned in the same direction. By storing the pots in a row in a row, the pots are correctly aligned in the entire area of the nursery box. However, since each paper nursery container is almost square and the number of pot rows is slightly different between the front and rear and the left and right, it is not possible to distinguish the front, rear, left and right of the container at a glance, and it is often the case. Then, the two paper nursery containers were stored and loaded in different directions, and the misalignment was noticed by looking at the misalignment of the pot rows. It is an object of the present invention to eliminate such a problem that a paper-made nursery container has.

[0004]

The characteristic structure of the present invention for achieving the above object comprises an opening for growing seedlings at the upper end, and a group of seedling pots opened downward are arranged in vertical and horizontal directions to form a seedling raising box. In a paper-made seedling raising container to be stored and loaded inside, the size is set so that two pieces can be arranged in the longitudinal direction in the rectangular shaped seedling raising box, and the long side of the seedling raising box in a state of being loaded in the seedling raising box is set. A plurality of small protrusions are integrally provided at predetermined intervals around the corresponding outer periphery of the container, and the action and effect thereof are as follows.

[0005]

As shown in FIG. 3, when the paper nursery container is small in size or the nursery box is large, the small projections face the inner wall surface of the nursery box in such a posture that the paper nursery box is made of paper. The movement of the nursery container is suppressed. When the paper nursery container has a large size or the nursery box is small, as shown in FIG. 4, the small protrusions are deformed according to the dimensional difference, and the paper nursery container is positioned. In this case, two paper nursery containers 1
When the seedlings are correctly stored and loaded in the seedling raising box 4, the small projections 5 are aligned with the long side of the seedling growing box 1 as shown in FIG.
Is a guide for checking the container storage orientation. In addition, when the small protrusions 5 are provided on the side corresponding to the short side of the seedling raising box 4, when the paper pot seedlings that have grown and are connected in series are loaded on the seedling stand of the rice transplanter in a vertical position, the front and rear papers are placed. Since the problem of poor continuity of pot seedlings occurs, small protrusions are provided only on the side corresponding to the long side of the nursery box.

[0006]

As described above, by using the paper-made seedling-growing container of the present invention, it is possible to suppress the displacement of the container when the paper-made seedling-growing container is stored and loaded in the seedling-raising box, and to make sure that the two paper-made seedling-growing containers have the correct posture. It was able to be stored and loaded in a nursery box with, and the function and handleability could be improved by a simple modification by simply providing small protrusions.

[0007]

EXAMPLE FIG. 2 shows the appearance of a paper-made nursery container 1 according to the present invention. This paper-made seedling-growing container 1 is a paper fiber paper product in which an opening 2 for growing seedlings is provided at the upper end, and a pyramidal-shaped seedling-raising pot 3 with a downward opening is connected vertically and horizontally, as shown in FIG. In addition, the two paper-made seedling-growing containers 1 are arranged and stored in the seedling-growing box 4 used for mat seedling growth in the longitudinal direction thereof. In one paper nursery container 1, the number of pots in the row parallel to the short side of the nursery box 4 and the number of pots in the vertical example parallel to the long side of the nursery box 4 are slightly different (1-2 And a pair of small projections 5 are provided at a predetermined pitch around the container a corresponding to the long side of the nursery box 4, and the two paper-made seedling containers 1 are oriented in the same direction with the small projections 5 as a guide. It can be stored and loaded in the nursery box 4. In addition, the small protrusions 5 have a projection amount set in advance in accordance with the inner size of the seedling-growing box 4 having a wide width, and when loaded into the seedling-growing box 4 having a wide width, as shown in FIG. Is less horizontal displacement,
Alternatively, it can be stored without lateral displacement, and when loaded in a seedling-raising box 1 having a small width, the small protrusions 5 are deformed as shown in FIG. 4, and the paper-made seedling-growing container 1 can be positioned and stored in the center of the width. Note that the seeding process step after the paper seedling raising container 1 is housed and loaded in this way is shown in FIG. 5, and the processing procedure will be described below. (A) First, the bed soil is fed into the seedling raising box 4 from above to fill the soil inside the seedling raising pots 3 and the joints between the pots. (B) Next, the upper soil is scraped off by the rotating brush 6 to form a recess in each upper end opening 2 of the seedling raising pot 3. (C) Next, the seeding guide plate 7 is mounted on the seedling raising box 4, and seed rice is supplied into the openings 2 of the seedling raising pots 3 in a predetermined number. (D) After that, cover soil is supplied from above and appropriate irrigation is performed, and this is transferred to the germination stage.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
