Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seedling raising tube for raising fruit and vegetable seedlings.

[0002]

[Prior art]

 In order to grow seedlings of fruits such as strawberries and vegetables such as eggplant, various containers for raising seedlings have been conventionally used. Typical examples thereof include a flowerpot-shaped container A as shown in FIG. 4, a cylindrical container B as shown in FIG. 5A, and a box-shaped container as shown in FIG. 5B. There is C. Bed soil D is put in these containers A, B, and C. For example, in the case of strawberry seedling raising, a vine called a runner is put into the bed soil D from a parent strain (not shown), and child seedlings are grown from this. .

[0003]

[Problems to be solved by the device]

 The conventional container for raising seedlings has a relatively large cross-sectional area and has a small hole for draining at the bottom, but it is a substantially closed container. For this reason, the roots of the seedlings grown in the container bend along the bottom wall of the container and become intricately entangled to form a dumpling, which hinders root growth and delays root growth and seedling growth after planting Honda. There was a problem.

It is an object of the present invention to provide a container for raising seedlings, which has less entanglement of roots in the container and obtains a seedling that is well lived after planting.

[0005]

[Means for Solving the Problems]

 The seedling-growing tube of the present invention is a tubular body having a tapered cross-section with a circular, elliptical or polygonal cross section, and the lower end of the tubular body is entirely opened, or the opening is provided with an opening. The earth stop member connected to the tubular body is integrally formed, and the total length of the portion where the earth stop member is connected to the tubular body in the circumferential direction of the tubular body is 1/3 or less of the circumferential length of the tubular body. It is made of synthetic resin.

[0006]

[Action]

 In the seedling raising tube of the present invention, the lower end of the tubular body is entirely open, or the earth retaining member connected horizontally from the inner wall at the lower end extends in the inner circumferential direction of the tubular body at the connection portion with the inner wall. Since the length is short and the opening that extends from the inner wall to the outside of the cylinder is wide, all or most of the roots that have grown along the inner wall exit from the opening to the outside of the cylinder and stop further growth. Promotes root growth. For this reason, there are few roots that are turned upside down or laterally, and there is less entanglement of roots in the cylinder.

Here, when the total length of the portion where the earth retaining member is connected to the tubular body main body in the circumferential direction of the tubular body is more than ⅓ of the circumferential length of the tubular body, the roots that have grown Since the area of the opening for leaving the outside of the cylinder from the lower end of the inner wall becomes small, and the number of roots reversing in the upward or lateral direction increases, the ratio should not exceed 1/3. Is 1/5 or less.

The taper formed in the tubular body helps the roots to extend straight downward, and also facilitates the withdrawal of seedlings from the tubular body.

【Example】

 FIG. 1A is a partially cutaway front view showing a seedling-growing tube according to an embodiment of the present invention, and FIG. 1B is a bottom view of the seedling-growing tube. FIG. 2 is a perspective view showing a state in which a seedling is being raised using the seedling raising tube of FIG.

The seedling-growing tube 1 of this embodiment is for raising strawberries. The tubular body 11 is made of synthetic resin and has a two-step taper with an outer diameter of about 45 mm at the upper end, an outer diameter of about 20 mm at the lower end, a thickness of about 1.5 mm, and a length of about 180 mm. It is.

A flange 12 for holding the seedling-growing cylinder 1 in the holding frame 2 at the time of raising seedlings is formed on the upper end of the tubular body 11, and an earth retaining member 13 is formed on the lower end.

As shown in FIG. 1B, the earth retaining member 13 is formed integrally with the tubular body 11 in a shape in which an annular piece is connected to the inner wall of the tubular body. The connecting portion with the wall has a total length in the circumferential direction of the tubular body that is approximately 1/7 of the circumferential length of the tubular body, and the area of the portion that extends horizontally from the tubular body wall is reduced. The area of the opening 14 communicating with the outside of the cylinder is widened.

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. Or, insert the runner 4 from the parent strain 3 into the nearby soil, and then transfer the roots that have rooted to the bed soil of the seedling raising tube 1 to continue rooting.

The rooted root extends downward along the inner wall of the seedling-growing tube 1. Most of the roots that have grown downward come out of the cylinder through the opening 14 and stop further growth when exposed to the outside air, and new roots grow one after another. Further, since the area of the earth stopping member 13 connected to the inner wall of the tubular body and extending horizontally is small, there are few roots which hit the earth stopping member 13 and are turned upside down or in the lateral direction. In this way, the seedlings 5 with less root entanglement and good survival after planting are grown. Further, by forming the soil stopping member 13, it is possible to prevent outflow of the bed soil due to irrigation or the like.

Further, in this embodiment, since the cross-sectional area of the seedling-growing tube 1 is smaller than that of the conventional one, excessive growth of secondary roots generated from the primary roots is suppressed, and entanglement of the roots is small, After rooting in Honda, the primary roots tend to emerge from the inside to the outside, and a seedling 5 with good growth after planting is obtained. Further, in the case of the present embodiment, the required bed soil is about 130 cc per piece, which is ⅕ or less as compared with about 700 cc of the conventional ordinary seedling raising container. Also, as shown in Fig. 2, even if a large number of seedling-growing cylinders 1 are arranged, a large space is not required, and the area is about 1/4 that of the conventional seedling-growing container.

When 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 holes for transplanting are small, it is easy to dig a hole and backfill, and the work efficiency is about 10 compared with the case of transplanting seedlings grown in a conventional container for raising seedlings. To double. In particular, in the case of diagonal planting where it is said that the root growth is improved and the yield is increased, the seedlings cultivated in the seedling raising tube 1 of this example need only be inserted with the solidified roots. It has good workability.

Since the roots of the transplanted seedlings are not entangled with each other and the growth of the primary roots is good, the seedlings grow smoothly by acclimating to the soil.

[0018] Furthermore, when the seedlings after raising the seedlings are refrigerated for promotion of flower bud differentiation and are transported, it is possible to store approximately four times as many seedling raising cylinders as the seedlings in the same space. And transportation efficiency is good.

FIG. 3A is a partially cutaway front view showing a seedling-growing tube according to another embodiment of the present invention, and FIG. 3B is a bottom view of the seedling-growing tube.

The seedling-growing tube 6 of this embodiment has a tapered tubular shape having a square cross section with an upper side of about 45 mm, a lower side of about 20 mm, a wall thickness of about 1.5 mm, and a length of about 180 mm. It is the body.

A flange 62 is formed on the upper end of the tubular body 61, and an earth stopper 63 is formed on the lower end.

As shown in FIG. 3 (b), the earth retaining member 63 is formed in a cross shape integrally with the tubular body 61, and the connecting portion with the inner wall of the tubular body is formed in the tubular body. The total length in the circumferential direction is set to about ⅙ of the inner circumference of the tubular body, and the area of the part that extends horizontally from the inner wall of the tubular body is made small, and the area of the opening 64 communicating from the inner wall to the outside of the cylinder is made wide. ing.

Similarly to the seedling-growing tube 1 shown in FIG. 1, the seedling-growing tube 6 of the present embodiment also has a small amount of root entanglement, and a child seedling with good survival after planting can be obtained.

Although the above embodiment is an example in which the cross-section of the tubular body is circular or square, the cross-sectional shape is not limited to circular or square, and it may be oval, triangular, rectangular or other polygonal shape. And so on.

The size of the tubular body is not particularly limited, but it is necessary to reduce the entanglement of roots, reduce the amount of floor soil required for each nursery tube, and arrange the nursery tubes. In terms of reduction of area, storage and transportation efficiency, the length is more than twice the diameter of the circular diameter, elliptical long diameter or polygonal inscribed circle, and the internal volume is 100 to 200 cm. ^It is preferably within the range of ³ .

[0026]

[Effect of device]

[Effect of device]

 The seedling raising tube of the present invention has the following effects. Since the opening that extends from the inner wall of the lower end of the tubular body to the outside of the cylinder is wide, all or most of the roots that extend from above exit the outside of the cylinder from the opening and come into contact with the outside air, stopping further growth. , One after another, encourage new root growth. At the lower end of the tubular body, the number of roots that are flipped upward or laterally is reduced, the entanglement of roots in the tube is reduced, and the roots grow soundly. The taper formed in the tubular body helps the roots to extend straight downward, and also facilitates the withdrawal of seedlings from the tubular body. There is little entanglement of roots, and it becomes easier for primary roots to emerge from the inside to the outside after planting Honda, so that a seedling with good growth after planting can be obtained.
