Description

[Detailed description of the invention] [Industrial application field] The present invention is a seedling transplantation method that can be used from raising plant seedlings to planting, and allows seedlings, etc., to be planted by burying them in the ground with their containers at the time of planting. This relates to containers for use.

[Prior Art] Conventionally, when planting plants such as trees, if the container for raising seedlings is made of clay, it is necessary to take out the seedlings from the container when transplanting to a planting site.
Because the work is troublesome and can easily damage the roots,
It can be used throughout the process from sowing and raising seedlings to planting.
There have been proposals for seedling raising containers that can be buried in the ground without removing the seedlings from the container during planting (for example, Japanese Utility Model Publication No. 53-3170, Publication of Japanese Utility Model Publication No. 58-91266). ).

[Problem to be invented or solved] In the former case, it is a container made of a particle foam molded product, and the roots of plants can penetrate through the fused parts between the particles of the peripheral wall and extend. Although it is made to be able to be planted, it is necessary to grow each seedling individually, and because the inner surface of the container has a circular cross section, it cannot be made from a particle foam molded product such as expanded polystyrene. For example, as shown in FIG.
It bends easily along the inner circumferential surface of the foam and cannot penetrate between the particles, and cannot sufficiently break through the fused parts between the foamed particles. This will result in poor adhesion.

In the latter case as well, it is possible to raise a large number of seedlings, but since the seeding hole has a circular cross section, if the seedling is made of a particulate foam such as Styrofoam, the roots will not be able to grow. It becomes difficult to break through the fused portions between the particles of the foam, causing the same problem as above.

The present invention was developed in view of the above, and takes advantage of the ability of roots to break through the fused portions between particles of a foamed particle molded product, by burying the seedlings together with their containers in the ground at the time of planting. It is an object of the present invention to provide a container for raising and transplanting seedlings which can be used for planting, in which the above-mentioned root penetration action can be reliably performed and the rooting can be achieved well during transplantation.

[Means for Solving the Problem] The present invention consists of a plurality of pots for raising seedlings, which are made of a synthetic resin particle foam molding and have an opening on the top surface and a drainage hole at the bottom, which are arranged in parallel in at least one direction vertically and horizontally and placed in the upper part. In order to solve the above problem, the inner peripheral surface of each pot part is bent inward and outward alternately at required intervals in the circumferential direction, so that each of the surfaces forms a corner part. It is characterized by being formed into a continuous uneven shape.

[Function] The above-mentioned container for raising and transplanting seedlings is used for raising seedlings by filling each square pot with seedling soil, sowing seeds or planting young seedlings, and transplanting after the seedlings of the plant have grown to a certain extent. At this time, each pot part can be separated by being broken between each pot part, and this can be directly buried and planted in a planting area such as an open field.

In particular, in the case of the present invention, the inner circumferential surface of each pot for raising seedlings is bent inward and outward alternately at required intervals in the circumferential direction, and each surface forms a unique uneven shape that is continuous through the corners. Therefore, when a root trying to extend outward hits the surrounding wall surface, it follows that surface to the outer corner, where it bends inward along the next adjacent surface and escapes. Instead, the tip of the root can easily sink into the fusion between the particles at the corner, thus breaking through the peripheral wall and extending to the outer periphery. If the angle of refraction of the outer corner is acute, the root penetration effect will be even better. Additionally, as plants such as trees grow further and their roots develop, the pot made of foamed particles breaks down, and its fragments and foamed particles get mixed into the soil, inhibiting the growth of plants such as trees. Never.

[Example] Next, an example of the present invention will be described based on the drawings.

In the figure, A indicates a container for raising and transplanting seedlings according to the present invention, which is mainly made of a closed-cell foam molded article of synthetic resin such as expanded polystyrene, and a large number of pots 1 for raising seedlings with openings on the upper surface are arranged in both vertical and horizontal directions or in one direction. They are arranged in parallel in the direction and connected at the upper part, and the lower part of each pot part 1 is formed separately so as to protrude downward from the connecting part 2. The number of pots 1 is determined depending on the usage mode.

The inner circumferential surface of each pot portion 1 is bent inward and outward alternately at each required time in the circumferential direction, and each surface is bent at the corner portion 3.
It is formed into a concave and convex shape that is continuous through the corners a and 3b, and as shown in the figure, the inscribed circle of each inner corner 3a and the circumscribed circle of each outer corner 3b are the lower part of the peripheral wall 4 of the pot part 1. It is formed so as to form a substantially concentric circle with the outer circumferential surface, and in the case of the figure, it is formed in a slightly tapered shape upward and downward. The uneven shape of the inner peripheral surface can be implemented by variously changing the number and angle of each corner 3a, 3b, but it can be implemented by setting the refraction angle at the outer corner 3b to be an acute angle. It is desirable to do so.

Reference numeral 5 designates drainage holes formed in all directions at the lower end of the peripheral wall 4 of each pot part 1. As the drainage hole 5, the peripheral wall 4
It is also possible to form it on two sides, or to provide it in one to several places such as the center of the bottom, as long as it has drainage properties necessary for raising seedlings.

6 and 7 are splitting grooves formed on the upper and lower surfaces of the connecting part 2 between the pots 1 and 1 in each row, and each pot part 1 can be divided at the splitting grooves 6 and 7. It's becoming like that. Although the splitting grooves 6 and 7 are not necessarily necessary, in order to facilitate division at the center between each pot part 1, a splitting groove is provided on at least one of the upper and lower surfaces of the connecting part 2. In particular, it is preferable to form a breaking groove on the lower surface side so that the container A can be easily broken by bending the entire container A upward. In particular, the breaking groove 7 on the lower surface side
If it has a V-groove shape as shown in the figure, the folding operation can be performed more easily.

The size of each pot 1 for raising seedlings in the above container A varies depending on the plant to be raised, but for example, the diameter of the inscribed circle of the inner corner 3a is 30 to 100 mm, and the depth is approximately the same as above. The thickness of the peripheral wall 4 is generally a minimum of about 10 mm. Of course, implementation with dimensions other than those described above is also possible.

The constituent materials of the container A include styrene resins such as polystyrene and copolymers mainly composed of styrene, olefin resins such as polyethylene,
Any synthetic resin that can be molded by particle foaming, such as mixed resins or other resins thereof, may be used, and in particular, a particle foamed molded product of a relatively hard closed-cell synthetic resin is particularly preferably used since it can be broken into each pot part. . The diameter of these expanded particles is preferably about 2 to 10 mm.

Container A for raising and transplanting seedlings of the present invention having the above configuration
contains soil such as culture soil in each pot part 1 for raising seedlings,
This is used to sow plants to be raised, or to plant seedlings that have germinated by sowing elsewhere, and to grow seedlings B for transplantation.
Drainage performance at this time is ensured through the drainage hole 5 at the bottom of the pot 1, and since it is made of particle foam, moisture and nutrients in the soil are well retained.

During the seedling raising, when the roots b that grow as the seedlings B etc. grow reach the peripheral wall surface of the pot part 1, the inner peripheral surface of the pot part 1 bends inward and outward alternately at required intervals in the circumferential direction. Because of this shape, the roots b that grow further are located at the corners 3a and 3 as shown in Fig. 5A.
It reaches the outer corner 3b along the slope of the wall surface between b, and since the adjacent wall surface is bent inward at the corner 3b, contrary to the above, the tip of the root b is adjacent to the outer corner 3b. It does not bend inward along the wall surface to be printed, but instead is caught between the foamed particles at the corner portion 3b, and the action of penetrating between the particles is sufficiently and well performed, as shown in Fig. 5 (b). As it grows, it penetrates the fused portion between the particles of the peripheral wall 2 and extends into the peripheral wall 2, and eventually penetrates the peripheral wall 2 and reaches the outer peripheral surface. That is, since the bond between the fused portions of the expanded particles is relatively weak, roots can grow through the fused portion.

In this way, when transplanting seedlings etc. B to a certain extent, the above-mentioned container A of the present invention is divided into individual pot parts 1 by bending them using the characteristics of the particle foam molding, and each seedling etc. The pot part 1
All you have to do is embed it in the ground in the planting area with the . The seedlings grow and grow, which allows for sufficient rooting.

In addition, as plants such as trees grow further and develop their roots, the pot made of foamed particles breaks down, and its fragments and foamed particles become mixed into the soil, causing the growth of trees and other plants. It does not inhibit the growth of plants.

[Effects of the invention] As described above, according to the container for raising and transplanting seedlings of the present invention, the unique uneven shape of the inner circumferential surface of each pot for raising seedlings prevents roots that are trying to extend outward from breaking inward. Without bending, it can reliably penetrate the surrounding wall by breaking through the fused parts between particles on the surrounding wall and extend to the outer periphery, so when transplanted to a planting site, it can be buried in the ground with the pot attached. The roots of this plant have extremely good rooting ability. This, combined with other effects such as lightness and ease of division due to the fact that it is made of particle foam molding, makes this seedling-raising and transplanting container suitable for planting by burying the entire container in the ground during planting. It can be used very suitably.
