BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising tube used for raising seedlings for raising seedlings from a runner extending from a parent strain such as strawberry.

[0002]

2. Description of the Related Art Conventionally, in order to grow seedlings of fruits such as strawberries and vegetables such as eggplant, a pot-shaped container, a cylindrical container or a box-shaped container has been used. Bed soil is placed in this container, and in the case of strawberry seedling raising, for example, a vine called a runner extending from the parent plant is inserted into the bed soil, and roots are grown in the bed soil to grow child seedlings.

As described above, in the method for raising seedlings in which the runner is inserted into the soil and the roots are grown, the tip of the runner needs to be fixed in close contact, and the roots grow when the runner wobbles due to wind or the like. It also interferes with root growth after planting Honda.

As a countermeasure against this, a straw, a wire or the like is deformed into a U shape and embedded in the soil from the upper part of the runner, and thereby the tip end of the runner is pressed to prevent the runner from wobbling.

[0005]

[Problems to be Solved by the Invention] However, when a fixture such as a straw or a wire is used, since the support force of the fixture is obtained on the floor soil in the container, it may be dried by rain or sun. As a result, the supporting force of the fixture is lost, and as a result, it is struck by the wind and escapes, making it difficult to keep the runner stable.

The present invention solves the above problems in fixing the runners, and an object thereof is to prevent the runners from moving with a relatively simple structure and promote the growth of the seedlings in the seedling raising container.

[0007]

[Means for Solving the Problems] The seedling-growing tube of the present invention is a tapered seedling-growing tube having a circular, elliptical or polygonal cross section, and a parent runner is fixed to the upper end of the seedling-growing tube. It is characterized in that a locking means is provided.

[0008]

In the seedling raising tube of the present invention, the runner extending from the parent strain is fixed to the locking means at the upper end of the seedling raising tube.
It is fixed stably regardless of the soil condition.

EXAMPLE FIG. 1 (a) is a partially cutaway front view showing a seedling raising tube according to an example of the present invention, and FIG. 1 (b) is a sectional view taken along the line AA of FIG. 1 (a). It is a figure. FIG. 2 is a perspective view showing a state in which child seedlings are being raised using the seedling raising tube of FIG.

The seedling-growing tube 1 of this embodiment is for raising strawberries, and the tubular body 11 is made of synthetic resin and has an outer diameter of about 4 at the upper end.
0 mm, outer diameter of the lower end is about 20 mm, wall thickness is about 1.5 m
It is a cylindrical body having a two-step taper of m and a length of about 150 mm.

A flange 12 for holding the seedling-growing tube 1 in the holding frame 2 at the time of raising seedlings is formed on the upper end of the tubular body 11.
A hook-shaped hook 13 for fixing the runner is formed on the upper surface of the flange 12. The hook 13 has elasticity and can be bent and used upward. Further, the side wall is provided with narrow openings 14 at four locations in the circumferential direction, and a soil stopper member 15 is formed at the lower end. 16 is a tubular body 11
Is the opening at the lower end of.

The opening range of the narrow opening 14 may be determined according to the length of the tubular body 11 and the type of seedling within the range where the primary roots of the seedling grow in the tubular body 11. Also, the earth stopping member 15
As shown in FIG. 1 (b), is an annular piece connected to the inner wall of the tubular body 11.

As shown in FIG. 2, the seedlings are raised by holding the seedling-growing tube 1 containing the bed soil with the holding frame 2 and inserting the runners 4 from the parent strain 3 into the bed soil of the seedling-growing tube 1. Root.

The rooted root extends downward along the inner wall of the seedling-growing tube 1, and a part of the root goes out of the tube through the narrow opening 14.
Growth is stopped by exposure to the open air, and new roots grow one after another. Most of the roots extending further downwards come out of the cylinder through the opening 16 at the lower end, come into contact with the outside air and stop growing, and new roots grow one after another. Further, since the area of the earth stopping member 15 connected to the inner wall of the tubular body and extending horizontally is small, the number of roots which hit the earth stopping member 15 and are inverted in the upward direction or the lateral direction is small. Thus, the seedlings 5 with less root entanglement and good survival after planting are raised. Further, by forming the soil stopping member 15, it is possible to prevent the outflow of the bed soil due to irrigation or the like.

Further, in this embodiment, as shown in FIG. 3, which is an enlarged view of the use state, a hook 13 is formed on the flange 12, and the runner 4 is fixed by this hook 13.
As a result, the runner 4 can be kept in close contact with the bed soil without being blown by the wind or the like, and the root growth of the seedlings 5 can be promoted.

At the time of planting, the seedlings 5 are extracted from the tubular body 11 together with the bed soil and transplanted to a ridge (not shown) or the like.
At this time, since the hole for transplanting is small, it is easy to dig a hole and backfill.

FIG. 4 is a perspective view showing a second embodiment of the present invention,
FIG. 5 is a perspective view of the rubber band shown in FIG.

The seedling raising tube 20 of this embodiment is provided with a slit 22 in a flange 21 at the upper end, and a rubber band 23 attached to the slit 22. The slit 22 and the rubber band 23 fix the runner 4 to each other. It is used as a locking means. Further, in order to prevent the rubber band 23 from slipping out, fixing portions 23 a having a width wider than the width of the slit 22 are formed at both ends of the rubber band 23.

In use, two slits 2 are formed so that the rubber band 23 is pressed from the upper surface of the runner 4.
Attach to 2. As a result, as in the above-described embodiment, the runner 4 is adhered to the soil without being blown by the wind or the like, so that root growth can be promoted. Particularly, in this embodiment, the runner 4 is attached to the surface of the rubber band 23.
Therefore, the adverse effect on the runner 4 can be reduced.

[0020]

[Effects of the Invention] According to the present invention, the runner can be securely fixed, especially even when the weather changes.
It can promote root growth of seedlings.
