Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plant cultivation support tool that supports a stem portion of a plant to be cultivated.

[0002]

[Prior art]

 Conventionally, when cultivating horticultural plants, etc., the upper surface of a flowerpot containing soil or a container containing a growing solution for hydroponic cultivation is covered with a lid to keep the root part of the cultivated plant warm and to block the sun's rays. The technology to do is known.

In particular, a lid used for hydroponic cultivation needs to have a supporting function for preventing the upper part from the stem of the plant from inclining or the plant falling into the cultivation container. , Was molded using plastic having the required rigidity.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional support for plant cultivation does not sufficiently correspond to the outer shape of the plant stem, and has a slight gap between the stem and the support, and insects and slugs can be seen from this gap. There is a problem that plants cannot be cultivated hygienically as upholstery because relatively small organisms such as species and dust invade.

Further, since the inside of the cultivation container can be seen through the gap, there is a problem that it does not look good as a plant cultivation tool indoors.

[0006] Therefore, the present invention solves the above-mentioned problems and provides a support for plant cultivation between the stem of the plant to be cultivated and the support so that small organisms such as insects do not enter the soil or the growing solution. The goal is to make it possible to cultivate plants in a hygienic manner with no gaps between them, and to make them look good in the state of display of cultivated plants.

[0007]

[Means for Solving the Problems] In order to solve the above problems, in the present invention, a hole that allows the stem of a plant to be cultivated to be inserted is formed in a lid that covers the upper surface of a cultivation container, and the edge of this hole is formed. Adopted a structure in which a gap filler made of a super absorbent polymer was molded into an annular shape.

[0008]

[Action]

 The support for plant cultivation according to the present invention, when water is absorbed by the gap filling material attached to the edge of the hole formed in the lid covering the upper surface of the cultivation container, it expands and adheres to the periphery of the stem of the plant to be cultivated. Then, the gap between the hole formed in the lid and the stem of the plant to be cultivated is sealed, and the stem is supported by an appropriate elastic force.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1 and FIG. 2, in the embodiment, a hole 3 through which a stem portion a of a plant A to be cultivated can be inserted into a disk-shaped lid 2 that covers the upper surface of a circular hydroponic cultivation container 1 made of plastic. And a gap filling material 5 formed by annularly molding a highly water-absorbent resin is attached to the edge of the hole 3 via an elastic bush 4 made of synthetic rubber.

The plants to be raised in this invention may be fruit trees for general horticulture, edible vegetables, ornamental flowers and the like. In addition, in addition to nitrogen, phosphoric acid, and potassium, which are required for such plants, trace elements such as iron, manganese, and boron, and vitamins are prepared and used as the growing solution.

Here, the plastic lid 2 is not particularly limited in its material, and may be foamed or non-foamed. However, in the one used for hydroponic cultivation, It is preferable to add a coloring material to have a light-shielding property.

The shape of the hole 3 through which the stem portion a can be inserted is not limited to the illustrated circular shape, but may be an elliptical shape, a polygonal shape such as a triangular shape or a square shape, or a well-known shape such as a fan shape.

As shown in FIG. 1, a peripheral groove 6 is formed on the outer periphery of the elastic bush 4, and the peripheral groove 6 is engaged with the peripheral portion of the hole 3. Further, the inner peripheral portion of the elastic bush 4 is formed to be thicker than the outer peripheral portion, and a wide peripheral groove 7 is formed on the inner peripheral surface, and the gap filling material 5 is fitted therein. The elastic bush 4 and the gap filling material 5 have cut surfaces 4a and 5a obtained by axially cutting a part of the ring, and the ring diameter is reduced so that the fitting work can be easily performed. .

The elastic bush 4 is preferably made of synthetic rubber having excellent water resistance, chemical resistance, and weather resistance, but the material is not particularly limited, and natural rubber can also be used. .

The highly water-absorbent resin, which is a molding material for the above-mentioned gap filling material 5, is a highly water-absorbent polymer and other thermoplastic resins having a property that water is not easily discharged even if an external pressure is applied after absorbing water. And the superabsorbent polymer is a water-insoluble three-dimensional network-like structure obtained by slightly bridging a polyelectrolyte having an ionic group. When water is absorbed, the polymer electrolyte of the superabsorbent polymer expands the polymer chain of the ionic group (hydrophilic group), and repulsion between the ions of the polymer electrolyte tends to expand the network. On the other hand, the bridging structure not only suppresses the force of expanding the mesh, but also prevents the water taken in the mesh from escaping.

Examples of the super absorbent polymer include a polyvinyl alcohol crosslinked product, a sodium acrylate-vinyl alcohol copolymer, a sodium polyacrylate crosslinked product, and an N-substituted acrylamide crosslinked product.

As the thermoplastic resin mixed with the superabsorbent polymer, polyethylene, polyvinyl chloride or the like can be used as long as it can be adjusted to have a hardness (JIS A) of about 50 degrees. When the mixing ratio at the time of mixing is thermoplastic resin: highly water-absorbing polymer in the range of 95: 5 to 80:20 (weight ratio), the volume change after water absorption is preferably 120 to 180%.

Here, if the volume change rate of the gap filling material 5 is less than 120%, the tightening of the stem portion of the plant becomes insufficient and the liquid tightness becomes low, which is not preferable. In addition, a high swelling property of more than 180% is not preferable because the plant is damaged by the tightening pressure.

As shown in FIG. 3, in order to use the above-described embodiment, the lid 2 is locked to the opening edge of the container for hydroponic cultivation, and a hole from the root of the plant A to be cultivated to the stem a is opened. 3 and then the elastic bushing 4 is screwed into the hole 3 in such a manner that the cut surfaces 4a are twisted so that the cut surfaces 4a are separated from each other, and the ring diameter is reduced. Make sure it fits in the circumferential groove 7. Then, it suffices that the gap filling material 5 in the mounted state is made to absorb water by spraying water or the like and swells so as to have a volume of 120 to 180% of the volume before absorption.

By doing so, the gap filling material 5 expands and elastically adheres to the periphery of the stalk of the plant to be cultivated, and the gap between the hole 3 formed in the lid 2 and the stem a of the plant to be cultivated A. The stalk is hermetically closed and the stem is supported with an appropriate elastic force. Therefore, it can be applied even when a cultivation method is adopted in which the cultivation container is designed to have pressure resistance and the growing liquid is pressurized.

Alternatively, as shown in FIG. 4, in order to use the above-described embodiment in the plant pot 8 containing soil, the lid 2 is locked to the opening edge of the plant pot 8 and the gap filling material 5 is attached as described above. Then, the plant A may be supported.

In addition, in the above-described embodiment, when the light shielding property is enhanced by adding a pigment to the lid 2, the elastic bush 4, and the gap filling material 5, it is possible to prevent discoloration due to light when the root vegetables are cultivated. It enables the cultivation of vegetables with higher commercial value.

[0023]

【effect】

 As described above, this device seals the gap between the hole formed in the lid and the stem of the plant to be cultivated, so that small organisms such as insects do not enter the soil or the growing solution. This makes it possible to cultivate plants in a hygienic manner, and the soil inside the cultivation container cannot be seen from the outside through the gap between the hole in the lid and the stem of the plant to be cultivated. There are advantages to be.
