DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for forming seaweed seeds and seedlings for use in marine forest development. More specifically, regardless of whether it is a new or existing structure, it is constituted by a structure such as a concrete block, and can be easily attached to a structure capable of functioning as a seaweed-growing substrate (hereinafter referred to as an epiphytic structure). A tool for supporting a seaweed seedling that is flexible with respect to the dimensions of the attachment portion of the settled structure is developed, and the seaweed seedling is pre-supported on the supporting tool, and the seaweed seedling is supported in the loaded state. The present invention relates to a seaweed seed and seedling formation technique for growing by attaching to a structure.

[0002]

2. Description of the Related Art Conventionally, as a method of creating a submerged forest composed of seaweeds such as the family Laminariaceae, a variety of devised cultures are installed in the sea, and the cultures are waited for natural growth of seaweeds. There is a known method of creating
No. 56199, Japanese Utility Model Laid-Open No. 4-71448). However, since these conventional methods are based on natural epiphytes, the growth status of seaweeds, which is particularly important in the early stage of development, is greatly influenced by uncertain natural factors and the development takes time. And there was a fundamental problem in terms of certainty.

[0003] Therefore, the seaweed seedlings are set in advance on a thin twisted yarn called seed seedling, and then wound directly on the set structure made of concrete block or the like and settled in the sea in that state. Attempts have been made to grow seaweed on the surface of the epiphytic structure with the nucleus as a nucleus. However, this conventional method is extremely difficult and unstable in attaching the seedlings to the epiphytic structure, and it is almost impossible to apply the method to an existing epiphytic structure already installed in the sea. Met. In addition, even after the attachment, if there is any problem in the attachment state of the seed and seedlings to the settlement structure, the attachment state is deteriorated from the problem point because it is thin and thread-shaped and unstable in shape. There was a drawback that it easily expanded and leaked. For this reason, this conventional method has not been put into practical use as an epiphytic method for seaweed seeds.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such technical circumstances, and can be easily attached to a newly-installed or existing settlement structure. Developing a flexible and easy-to-use seaweed seed-bearing tool for the dimensions of the attachment portion of the raw structure, the seaweed seed (in the present invention, such as a precursor of a young body, a young body, a mature body, etc.) (Each growth stage is included) by attaching to the above-mentioned epiphytic structure in a state of carrying, thereby simplifying the epiphytic work of seaweed seeds and stabilizing the epiphytic state. It is the purpose.

[0005]

According to the present invention, in order to achieve the above object, a ring-shaped holding tool is formed from end-shaped members, and a seaweed seedling is supported on the holding tool. A technical means was adopted in which seaweed seedlings were grown by attaching to the outer peripheral portion of the columnar portion of the epiphytic structure for use. In addition, a support tool having an appropriate shape such as a straight line is formed from a bendable end-shaped member, and a seaweed seedling is held on the support tool. A technical means was adopted in which seaweed seedlings were grown by attaching to the outer peripheral portion of the columnar portion of the epiphytic structure for use. As described above, since the carrying tool of the present invention is formed in a ring shape from an end-shaped member, the size of the ring shape can be easily adjusted in accordance with the diameter of the columnar portion of the settlement structure. There is a characteristic. When attaching the support tool to the settlement structure, use a support tool that is formed in a ring shape in advance, or is formed into a ring shape at the time of attachment or the like, and the columnar shape of the settlement structure is used. Attachment to the part greatly facilitates the attachment work because of the form of the carrying tool, ie, the ring shape, and the fact that the attachment part is a columnar part. Therefore, since the attaching work can be performed relatively easily even in the sea, it can be applied not only to a newly formed structure but also to an existing structure. Furthermore, since the carrying tool after being attached to the settlement structure itself stably retains a ring shape,
As long as the carrying tool itself does not flow out, it does not easily flow out as in the prior art using seed and seedlings.

A so-called tetrapot (registered trademark) made of a concrete block in which four new or existing truncated conical pillars are formed radially is used as the above-mentioned underwater forest formation epidemic structure. It is also possible to apply the above-mentioned support tool to the truncated cone-shaped column. Further, by connecting the plurality of the carrying tools with each other with a connecting member, it is possible to prevent the supporting tools from flowing out from the columnar portion, to provide a connecting means at an end of the carrying tool, or to provide a connecting means. , The diameter of the ring can be adjusted, or the support tool and the epiphytic structure or one of the surfaces thereof can be coated with an algal coating to promote the growth of the seaweed seeds.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the present invention can be applied to a newly-installed and an existing settlement structure. The epiphytic structure may be any one having a columnar portion to which the above-mentioned ring-shaped support tool can be attached, such as a concrete block such as a so-called Tetrapot (registered trademark), a natural stone, and a rock on the sea floor. It may be composed of Further, a pillar made of natural wood such as thinned wood, concrete, synthetic resin, metal or the like may be erected on a concrete block or the like. Further, the cross-sectional shape of the columnar portion is not necessarily required to be circular, but may be another cross-sectional shape. The columnar portion is not necessarily limited to the one provided in a vertical state, and may be a columnar portion formed in a horizontal direction or the like. In short, it is sufficient that a ring-shaped support tool that can be adapted according to the cross-sectional shape can be formed, and the formation structure has a columnar portion that can be easily attached.

The carrying tool is formed in a ring shape in advance or at the time of attaching the settlement structure to a columnar portion, and the ring shape is formed by the elasticity of the material itself or a hooking means provided at an end portion. Any material can be used as long as it can be held even after attachment, and is formed of a suitable material such as an endless bamboo material, plastic, rubber, metal, or the like, such as a strip or rod having an appropriate length. Specific examples of plastic include:
Examples of materials having elasticity include ethylene-vinyl acetate copolymer, various thermoplastic elastomers, polyarylate, and polyurethane. In addition, if a biodegradable plastic (for example, “Bionole” manufactured by Showa Polymer Co., Ltd.) is used, the supporting tool is decomposed by microorganisms after the formation of seaweed. Since the utensil does not flow away from the set structure, it is of course possible to use a general polymer material such as polypropylene or polyethylene having no biodegradability. Specific examples of the metal include, for example, spring steel such as a piano wire, and other metal wires that can be easily plastically deformed, or these wires are made of synthetic fibers such as Cremona seedlings (trade name). For use as a core material of fibrous materials such as twisted yarn and sashimi rope. In addition,
In the case of zoospores and gamete bands (hereinafter collectively referred to as juvenile precursors) as seaweed seeds and those that cannot be directly attached by hand, such as very small juveniles, Since it is necessary to immerse the supporting tool in a water tank in which the precursor is present and to support it, it is desirable to use these fibrous materials together even when using plastic, rubber, or bamboo. The specific material of the supporting tool is selected in consideration of the elasticity of the material, its degree, rigidity, corrosion resistance, and the like according to the form of the supporting tool.

[0009] The form of the carrying tool is roughly divided into
It is formed in a ring shape in advance, and when attaching to the columnar portion of the above-mentioned settlement structure, both ends are expanded, and the columnar portion is attached through the columnar portion from between the both ends, or the columnar portion is separated from the end. A type A in which the fitting position is adjusted by further expanding the diameter and a suitable shape such as a linear shape from a bendable member. Type B that is used by bending it into a ring shape according to
There is. In both of these types, since the carrying tool is formed from an end-shaped member, not only the mounting method of externally fitting from the end of the columnar portion, but also the mounting at the lateral direction of the columnar portion by expanding both ends. That the mounting position can be adjusted by adjusting the diameter thereof, and that the holding tool retains a ring shape in a state where the mounting tool is attached to the columnar portion of the settlement structure. They are common in that they do. In addition, the number of turns of the ring shape is not limited to one, and may be formed in a coil shape.

[0010] By further providing a connecting means for connecting the ends of the support tool to each other, it is possible to simplify the work of attaching the epiphytic structure to the columnar portion and to form a stronger ring. it can. Further, by adding a length adjusting function to the connecting means, it is possible to widen the adaptability of the carrying tool. Furthermore, as exemplified in the description of the examples below, by providing a supporting means for supporting the seaweed seeds on an appropriate portion of the supporting tool, the work of supporting the seaweed seeds can be simplified.
In addition, as the seaweed seedling, it is possible to use a seaweed larvae precursor that has settled on Cremona seedling thread (trade name) or the like, or a seaweed larva or mature body that is supported on the above-mentioned holding tool as it is. it can. As the algae coating applied to the supporting tool and / or the epiphytic structure or one of them, a photosynthetic bacterium, a carrier using porous particles, and a water environment improving paint containing a nutrient component of the photosynthetic bacterium (Japanese Patent Application Laid-Open No. HEI 5- -247378
And the like, which are effective in promoting the development of marine forests.

In the case where the seaweed seeds and seedlings are set on the epiphytic structure using the above-mentioned supporting tool, the target for the supporting tool is not affected by any of the above-mentioned types of supporting tool. Seaweed seedlings are preliminarily supported and, depending on the stage of growth of the seedlings, are cured in an aquarium or the like, and in the case of a new construction, the supporting tool supporting the seaweed seedlings is placed on the columnar portion of the epiphytic structure on land or on a barge. It is worn and settled in the creation sea area. Further, in the case of the existing, similarly, the above-mentioned supporting tool supporting the seaweed seeds is attached to the columnar portion of the existing epiphytic structure in the sea. And type A
When using the carrying tool, the supporting tool is attached to the outer periphery of the column by expanding the both ends of the supporting tool as described above and passing the column through the space between the ends, or by externally fitting from the end of the column. . On the other hand, when using a type B carrying tool,
At the time of attachment, the support tool is curved in a ring shape along the outer peripheral surface of the columnar portion of the settlement structure, or is previously curved in a ring shape matching the columnar portion and is attached to the outer peripheral portion of the columnar portion. To wear. In addition, at the time of attachment, the attachment position can be adjusted by adjusting the diameter of those carrying tools as needed. Furthermore, in this case, when the carrying tool itself has elasticity, the carrying tool can be fixed to the columnar portion by its own elastic force.However, a connecting means for connecting both ends of the carrying tool is used. In the case where it is provided, after the attachment position is adjusted, it can be fixed more securely by tightening via the connecting means. In addition, a wedge is struck between the carrying tool and the columnar portion, an adhesive or a hardening material is filled therebetween, an anchor member is struck on the columnar portion side, and the supporting tool is fixed using the anchor member. It is also possible.

FIG. 11 illustrates a specific means for forming an insertion space for supporting the seaweed seed and seedling 2, which can be applied commonly to the above embodiments.
The means shown in (a) is for forming an insertion space by making a cut in the upper and lower portions of the carrying tool itself and curving the intermediate portion 56 thereof, except that the intermediate portion 4 is formed in the carrying tool itself.
This is the same as in the case of No. 6. The means shown in (b) forms an insertion space by previously attaching a member 57 for forming an insertion space to the carrying tool itself in advance. Note that, in this case, a bottomed pocket-like space is formed by the member 57, into which a seaweed seedling composed of a juvenile precursor that has settled on a spongy carrier can be inserted. May be configured. The means shown in (c) forms the insertion hole 58 in the carrying tool itself.

In the embodiments shown in FIGS. 7 to 11, the edges of the supporting portions in contact with the stems of the seaweed seedlings 2 are described as having corners, but they are rounded or warped outward. This is effective in preventing damage to the seaweed seeds 2. Furthermore, for example, when a sponge formed in a tube shape is cut in the longitudinal direction and the sponge is supported in a state where the stem is wrapped from the side, the sponge becomes a cushion material. Or
The seaweed seed and seedling 2 can be effectively protected against the fluctuation caused by the tide. In addition, the seaweed seeds 2 may be sandwiched from both sides by the foamed resin sheet. In this case, if an adhesive layer is provided on the back side of the sheet, it becomes difficult to move when mounted on the carrying tool 30, so that workability is improved. improves. Further, in the above embodiment, the seaweed seeds 2 are carried on the stem portion, but may be carried near the temporary root portion which is lower than the stem portion. In the embodiment shown in FIG. 9, the seaweed seeds 2 are supported outside the middle receiving member 32.
