Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container for raising seedlings for raising seedlings of fruits and vegetables.

[0002]

[Prior Art]

 As a container for growing seedlings of fruits such as strawberries and vegetables such as eggplant, the upper parts of a plurality of cylindrical or box-shaped unit containers A as shown in (a) and (b) of FIG. There is a synthetic resin container for raising seedlings. Bed soil B is put into each unit container A of these seedling raising containers. For example, in the case of strawberry seedling raising, a vine called a runner is put into the bed soil B from a parent strain (not shown) to grow child seedlings.

[0003]

[Problems to be solved by the device]

 In the conventional container for raising seedlings as shown in FIG. 6, the cross-sectional area of the unit container A is relatively large, and the bottom has a small hole for draining water 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 are intricately entangled to form a dumpling, which hinders the root growth and prevents the root growth and seedling growth after planting Honda. There was a problem of slowing down the growth of.

Further, since the entire container has a small wall thickness and a low strength, it is used by placing it on the floor board C as shown in FIG. Therefore, when a large number of seedling raising containers are used, a large number of large-sized floorboards C are required.

An object of the present invention is to provide a container for raising seedlings which has less entanglement of roots of seedlings in a unit container, can obtain a child seedling with good survival after planting, and has sufficient strength. It is in.

[0006]

[Means for Solving the Problems]

 In the container for raising seedlings of the present invention, an inclined portion of an inverted truncated cone shape or an inverted truncated pyramid shape having an opening at the center is formed inside the flat portion of each of the divided sections in a plane. A container for raising seedlings made of synthetic resin is provided with a through hole having a circular or polygonal cross section having a tapered taper following the opening.

Foamed synthetic resin or dense synthetic resin can be used as the material of the container for raising seedlings. When foamed synthetic resin is used, the overall shape is roughly rectangular and the inclined part and the through hole are integrally molded, or the through hole part is cylindrical and integrally molded with the inclined part. be able to. When a dense synthetic resin is used, the through hole portion can be formed into a tubular shape and integrally molded with the inclined portion.

The thickness of the flat part and the sloped part of the upper part of the container for raising seedlings is 10 mm or more when the foamed synthetic resin is used, and 0.5 mm or more when the dense synthetic resin is used to ensure strength. The parts may be provided with hooking parts for engagement at opposite side edges.

The size of the through holes and the number of seedlings per seedling growing container are not particularly limited, but the entanglement of the roots of the seedlings during growing is reduced and the required amount of floor soil per throughhole is increased. From the viewpoints of reduction and ease of handling the container for raising seedlings, the size of the through hole is at least twice the diameter of the circular diameter or the diameter of the inscribed circle of the quadrangle, and the internal volume is 100 to 200 cm. The number of through holes is preferably within the range of ³ , and the number of through holes is preferably as large as possible within the range where the maximum dimension of one side when viewed from the plane of the whole seedling-growing container is 1200 mm or less.

[0010]

[Action]

 In the container for raising seedlings of the present invention, the through hole having the tapered taper corresponds to an individual unit container for raising seedlings. All or most of the roots that have grown from above in this through hole exit from the opening at the lower end, stopping further growth and promoting the growth of new roots. As a result, there are few roots that flip upward or laterally, and there is less entanglement of roots in the holes. Also, the taper of the through holes facilitates the withdrawal of seedlings from the holes.

Further, since the upper part of the container is thick and has sufficient strength, it can be locked to an appropriate holding device by utilizing the locking hooks on the side edges.

Further, when water or liquid fertilizer is applied to the seedlings being raised, the water or liquid fertilizer is likely to flow along the inclined portion above the through hole.

[Effect of the device]

 The container for raising seedlings of the present invention has the following effects.

Since the lower end of the through hole is open, all or most of the roots extending from above go out of the opening and come into contact with the outside air, and stop growing further, and new roots grow one after another. Encourage growth.

At the lower end of the through hole, the number of roots that are flipped upward or laterally is reduced, the number of root entanglements in the hole is reduced, and the root grows soundly.

The taper of the through holes helps the roots to grow straight down and also facilitates withdrawal of the seedlings from the through holes.

There is little entanglement of roots, primary roots tend to emerge from the inside to the outside after planting Honda, and a seedling with good growth after planting can be obtained.

Since the container for raising seedlings can be locked to the holding device by using the locking hook, the conventional floor plate is not required.

When water or liquid fertilizer is applied to the seedlings being raised, the water or liquid fertilizer is likely to flow along the upper inclined portion of the through hole, and wasteful consumption of water or liquid fertilizer can be prevented.

In the case of summer seedlings, roots in a container are protected from high temperature damage, and in the case of strawberries, for example, a flower bud differentiation effect similar to that in highland cultivation can be obtained.
