BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for raising seedlings for growing fruit and vegetable seedlings.

[0002]

2. Description of the Related Art A plurality of cylindrical or box-shaped unit containers as shown in FIGS. 6A and 6B are used as containers for growing fruit seedlings such as strawberries and vegetables and eggplants. There is a container for raising seedlings made of synthetic resin in which the upper portions of A are connected to each other. In each unit container A of these seedling raising containers, floor soil B is put. For example, in the case of strawberry seedling raising, a vine called a runner is inserted into floor soil B from a parent strain (not shown), and seedlings are grown from this.

[0003]

The conventional seedling raising container as shown in FIG. 6 has a relatively large cross-sectional area of the unit container A, and its bottom has a small hole for drainage but is almost closed. For this reason, the roots of the seedlings grown in the unit container A bend along the bottom wall of the unit container A and become entangled in a complicated manner to form a dumpling, hindering the growth of the roots, growing the roots after planting Honda, and growing the seedlings. Had the problem of slowing the growth of

[0004] Further, since the entire container is thin and has low strength, it is mounted on a floor plate C as shown in FIG. Therefore, when a large number of containers for raising seedlings are used, a large number of floor plates C having a large size are required.

[0005] An object of the present invention is to provide a seedling container capable of obtaining seedlings having a small root entanglement in a unit container, having good root survival after planting, and having sufficient strength. is there.

[0006]

The container for raising seedlings according to the present invention comprises:
For each section divided into a plurality of sections in a plane, the upper peripheral portion is a flat portion, and an inverted truncated cone or inverted truncated pyramid shaped inclined portion having an opening in the center is formed inside the flat portion, and the tapered portion is tapered following the opening. have a Jo of the tapered portion and the lower end opening of growth root
Formed a through-hole with an opening area large enough to allow passage
It is characterized by the following.

[0007] As a material for the container for raising seedlings, a foamed synthetic resin or a dense synthetic resin can be used. When using a foamed synthetic resin, the entire shape can be substantially rectangular and the inclined portion and the through-hole can be integrally molded, or the through-hole portion can be cylindrically molded integrally with the inclined portion. . When a dense synthetic resin is used, the through-hole portion can be formed in a tubular shape and integrally formed with the inclined portion.

When the foamed synthetic resin is used, the thickness of the upper flat portion and the inclined portion of the container for seedling raising should be 10 mm or more.
When a dense synthetic resin is used, it is preferable to secure the strength to 0.5 mm or more.

The size of the through hole and the number per seedling container are not particularly limited, but the entanglement of the roots of the seedlings during growth is reduced, and the required amount of floor soil per through hole is reduced. From the viewpoint of reduction and ease of handling of the seedling raising container, the size of the through-hole should be at least twice as long as the diameter of a circular or square inscribed circle, and the internal volume should be 10 or more.
The number of through-holes is preferably in the range of 0 to 200 cm ³ , and the number of through-holes is preferably as large as possible within a range where the maximum dimension of one side viewed from the plane of the entire container for seedling raising is 1200 mm or less.

[0010]

In the seedling raising container of the present invention, the tapered through-holes correspond to individual seedling raising unit containers. All or most of the roots extending from above in the through-hole exit from the opening at the lower end, stop further growth, and encourage new root growth. Therefore, the number of roots that invert upward or laterally is reduced, and the entanglement of the roots in the holes is reduced. Also, the taper of the through-hole facilitates pulling out of the seedling from the hole.

[0011] Also, provided at opposite side edges of the upper portion of the container.
It was by using the locking hook can be locked in a suitable holding device.

In addition, when water or liquid fertilizer is applied to the seedlings being raised,
Water and liquid fertilizer can easily flow along the inclined portion above the through hole.
