Description

The present invention relates to a seaweed reef equipped with a seaweed growing tool capable of effectively transplanting seedlings of seaweed, particularly Honda walla.

  Conventionally, as a seedling transplanting method of perennial seaweed, using a string-like body for growing a seedling, fertilizing, germinating and raising a seedling, and a wooden plate for fixing the string-like body, The string-like body on which the seedlings grew after the growing period is fixed to a wooden plate, and the wooden plate on which the string-like body is fixed is attached to a concrete block and set in the sea or attached to a bedrock in the sea. It is known that the roots of seedlings can be fixed on a concrete block or a bedrock beyond a wooden flat plate (see, for example, Patent Document 1).

JP 2002-171854 A

  However, the conventional seedling transplanting method has a problem that seedlings are overcrowded on the string-like body and growth is likely to be suppressed. In addition, depending on the growth stage of the seedlings to be transplanted, the expected effects may not be obtained due to feeding damage from herbivorous animals.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to make it possible to effectively perform seedling seedling transplantation in particular.

For the above-mentioned purpose, the present invention is attached to the cylindrical net with the central axis lying sideways and a seedling seedling of seaweed attached to the upper part, with an interval from the upper part of the cylindrical net , A seaweed breeding tool having a fixed substrate for fixing a root of seaweed attached as a seedling to the upper part of the cylindrical net, crushes a portion protruding below the fixed substrate of the cylindrical net, and the fixed substrate Ru der provides a seaweed reefs, characterized in that attached to algal礁本body through.

The seaweed breeding tool used in the present invention is used by attaching seedlings to a tubular net, and by attaching seedlings at appropriate intervals, it is possible to prevent poor growth due to the seedlings becoming overcrowded, By making the seedlings to be attached to the cylindrical net up to an appropriate state, it is possible to suppress feeding damage from herbivorous animals.

The seaweed breeding tool used in the present invention has a fixed substrate in the cylindrical net or at the bottom of the cylindrical net, so that the roots extending from the seedlings attached to the cylindrical net are fixed on the fixed substrate, and then stable. Can promote growth.

Mojo礁 of the present invention, the seaweed growing device, for example, those that were attached to the algae礁本body such as a concrete structure, can be fixed by extending seedlings roots from the fixed substrate to further algae礁本body , Can form a stable seaweed bed. Moreover, the fixed substrate in the seaweed breeding tool used in the present invention can be used as an attachment member at the time of attachment to the alga reef body, and attachment work is facilitated and a firm attachment state is easily obtained.

  Hereinafter, the present invention will be further described with reference to the drawings.

FIG. 1 is a perspective view showing an example of a seaweed breeding tool used in the present invention , and FIG. 2 is a side view of a state in which seedlings are attached to the seaweed breeding tool of FIG.

  As shown in FIG. 1, the seaweed breeding tool 1a of this example includes a cylindrical net 2 having a central axis and a fixed substrate 3 that is inserted into the cylindrical net 2 and attached substantially horizontally. It has become a preparation.

  The cylindrical net 2 is a cylindrical net or bowl-like material, and can be formed of, for example, fiber reinforced plastic. More specifically, the fiber bundle impregnated with the synthetic resin can be wound around the mandrel in an appropriate net or cage shape, the impregnated synthetic resin is cured, and then extracted from the mandrel.

  The illustrated cylindrical net 2 is cylindrical, but may be a rectangular cylinder or an elliptic cylinder. In addition, the cylindrical net 2 can be elastically deformed so that the portion protruding below the fixed substrate 3 can be crushed and stabilized when attached to the alga reef body 4 (see FIG. 5) described later. Is preferred.

  The fixed substrate 3 is in the form of a flat plate having fine irregularities on the surface so that the roots of hondawala can be easily fixed. Specifically, a concrete board or a synthetic resin board whose surface is roughened can be used.

  The fixing substrate 3 is attached to the cylindrical net 2 by, for example, forming a hole in advance or attaching a metal fitting to the side edge of the fixing substrate 3, and using this hole or metal fitting, a wire, a string, a rope, etc. It can carry out by fixing to the cylindrical net | network 2 with the fastening means of. Further, the fixed substrate 3 shown in the figure is provided at substantially the center of the cylindrical net 2 so as to bisect the cylindrical net 2 substantially vertically. It can also be attached.

  As shown in FIG. 2, the seaweed breeding tool 1 a of this example is used with a seedling 5 attached to a portion above the fixed substrate 3 of the cylindrical net 2. The seedling 5 can be attached with a string or a band. As the seedlings 5, Honda straw is most suitable. In particular, in the case of this example, since the fixed substrate 3 is provided immediately below the attachment portion of the seedling 5, the root 6 extending from the seedling 5 can be easily fixed on the fixed substrate 3.

Figure 3 is a perspective view showing a reference example of sea algae farming tool, Fig 4 is a side view of the state of attaching the seedling seaweed growing device of Figure 3.

The seaweed breeding tool 1b of this reference example is basically the same as the seaweed breeding tool 1a shown in FIG. 1, as shown in FIG. 1 is different from the seaweed breeding tool 1a in FIG.

As shown in FIG. 4, the seaweed breeding tool 1 b of the present reference example is used with a seedling 5 attached to a cylindrical net 2 on a fixed substrate 3. In particular, the seaweed breeding tool 1b of the present reference example has the advantage that it is easy to stabilize when attached to the alga reef body 4 (see FIG. 6) and the like, which will be described later, because the fixed substrate 3 is exposed on the lower side. In addition, as compared with the seaweed breeding tool 1a of FIG. 1, the interval between the seedling 5 and the fixed substrate 3 is likely to be large. For example, the interval is fixed to the short diameter side of the cylindrical net 2 having an elliptical cylindrical shape. It can also be adjusted by attaching the substrate 3 or the like.

  FIG. 5 is a perspective view showing an example of the seaweed reef according to the present invention.

  The seaweed reef 7a of this example has the seaweed breeding tool 1a of FIG. The seaweed breeding tool 1a is attached by crushing the portion of the cylindrical net 2 protruding below the fixed substrate 3 and pressing the fixed substrate 3 against the surface of the algal reef body 4. The seaweed breeding tool 1a can be attached to the algal reef body 4 by using bolts or metal fittings embedded in the algal reef body 4 in advance, or tied with a wire, rope, string, or the like. Further, by connecting the seaweed breeding tool 1a to the algal reef body 4 through the fixed substrate 3, the attachment to the algal reef body 4 can be easily and strengthened.

  The algae reef body 4 is not particularly limited as long as it can hold the seaweed breeding tool 1a and can be stably deposited on the sea floor, and for example, a concrete structure can be used.

  As described with reference to FIG. 2, the seaweed reef 7a is formed by attaching seedlings 5 to the tubular net 2 of the seaweed breeding tool 1a and sinking the seedlings 5 to the seabed. It extends to the surface of the reef body 4 and firmly settles and grows.
