JP 2003-111530 A

  According to the above method, if the seedlings of sea eels are transplanted together with biodegradable pots in a sand transplanting site, the seeds will grow and the roots and rhizomes will grow until the pots biodegrade in the sea. I can't go out. Therefore, the root of the eel was poor and the rhizome could not extend to the surroundings, so the flounder was insufficient. In addition, it was necessary to secure such a water area when trying to grow sea eel seedlings in a calm water area.

The purpose of the present invention is to enable easy growth of eelgrass seedlings in containers, and when the larvae seedlings are placed on the seabed and the seedlings grow and the roots and rhizomes grow, the containers will grow. It is to provide a method for nurturing eelgrass seedlings and eelgrass farms that will not hinder them.

According to the first aspect of the present invention, there is provided a method for nurturing eelgrass seedlings and creating eelgrass fields by sewing a woven fabric, a knitted fabric, or a nonwoven fabric made of one of biodegradable fibers and natural fibers into a box-shaped or bag-shaped body. A hanging string made of the above fibers is attached to the container, and in the case of a woven fabric, the texture of the knitted fabric, in the case of a knitted fabric, the stitches of the whole, and in the case of a non-woven fabric, the voids that are present throughout the root of the ammo and the rhizome, respectively. Distribute any number of containers for breeding sea cucumber seedlings and cultivating sea urchin farms to multiple households, in each household, put a predetermined amount of sand in the container, sow seeds of sea eel, and then saturate the container with seawater Put in a bottle filled with water, submerge it in seawater in the bottle, detachably fasten the upper end of the hanging strap on the back of the lid, apply the lid to the bottle, and when the eel seeds germinate and seedlings grow, Open and hang from lid Remove the hanging strap, hang the container from the bottle with the hanging strap, collect the eelgrass seedling raising and eelgrass seedling raising containers taken out of the jar from each household, and keep them in the eelgrass site creation sea area as they are It is transported and distributed on the sea floor to create an ammo field .

  In the invention of claim 1, the woven fabric is preferably a plain fabric or a twill fabric. As the knitting, both lace knitting and knitted knitting can be used. Moreover, 0.1-4 mm is suitable for the thickness of a container. If the thickness is less than 0.1, the container is too thin, which is not preferable in terms of shape retention. If the thickness exceeds 4 mm, the root of the eel and the rhizome are difficult to go out of the container.

According to the second aspect of the present invention, there is provided a method for cultivating eelgrass seedlings and creating an eelgrass field, wherein any one of a biodegradable fiber, a biodegradable synthetic resin, and a natural fiber is used as a molding material and is molded into a pot-shaped container. multiple holes are drilled capable through at least a bottom wall and body wall height roots and rhizomes of seagrass in the middle below of the total volume body, and hanging strap is attached made of the fibers in this condition eelgrass Distribute an arbitrary number of seedling-growing and eelgrass farm containers to multiple households. At each household, put a predetermined amount of sand in the container and seed seeds of eel, and then place the container in a jar filled with seawater. Then sunk into the water in the bottle, and the top of the hanging string is removably attached to the back of the lid, and the lid is applied to the bottle. When the eel seeds germinate and the seedlings grow, the lid is opened and the hanging string is pulled from the lid. And remove it with a hanging strap. The container for raising sea cucumber seedlings and the eel stock farm construction that has been taken out from the jar is collected from each household, transported as it is to the sea shore construction ground area, and distributed on the sea floor, Is to create .

In the invention of claim 2, the shape of the hole may be round or square, but in the case of a round hole, the diameter is preferably 6 to 8 mm. If the rhizomes from the roots becomes thick, but the thickness of the Ru 6mm about der.

In the above SL claims 1 and 2, specific examples of the biodegradable fibers can be cited polylactic acid, polybutylene succinate adipate, polyvinyl alcohol, polycaprolactone and fatty acid polyesters and the like. Further, specific examples of natural fibers, coconut, hemp, Ru can be mentioned cotton and wool.

According to 請 Motomeko 1 and 2 of the eelgrass seedlings grown and eelgrass beds reclamation process according to the invention, since the cord suspended condition of container seagrass seedlings for cultivating and eelgrass beds reclamation are attached, a predetermined amount of sand receptor Put the seedlings in the bottle, then put the container in a bottle filled with seawater and submerge it in the water. Put the upper end of the hanging string on the back of the lid so that it can be removed and put the lid on the bottle. When the seeds germinate and the seedlings are grown, the lid is opened, the hanging string is removed from the lid, the container is suspended from the bottle by the hanging string, and the eelgrass seedling growing and eelgrass farm building container is left as it is. It can be transported to the sea area and distributed on the bottom of the sea to create an ammo field. Moreover, seagrass seedlings for cultivating and eelgrass beds Construction container's condition that definitive to a first aspect of the invention, woven, knitted or nonwoven fabric, brought sewing in a box-like or bag-like, in the case of a woven fabric that texture is, when knitting the stitches, the voids present in the entire case of the nonwoven fabric, respectively are adapted to be passed through the roots and rhizomes of eelgrass, eelgrass seedlings for cultivating and eelgrass beds Construction container for definitive to the second aspect of the present invention Since the body of this plant has a large number of holes that allow the roots and rhizomes to pass through the roots and rhizomes of the whole body, when the seedlings grow and the roots and rhizomes grow on the seabed, the contents become obstacles to their growth. Don't be. Therefore, the roots and rhizomes grow in the ground, and despite the presence of the body, the eels are firmly rooted in the ground and sufficiently thrive with the sprout that grows from the rhizomes. Furthermore, eel grass seedlings for cultivating and eelgrass beds Construction container for definitive to the invention of claim 1 is intended receptor and hanging cord material consisting either of the fibers of biodegradable fibers and natural fibers, claim seagrass seedlings grown for and eelgrass beds Construction container for definitive to the present invention 2, since these biodegradable synthetic resin on the outer can and is used alternatively, the eel grass seedlings for cultivating and eelgrass beds Construction container to the seabed After the dispersive arrangement, this will decompose and disappear over time. Therefore, it does not impair the sea area environment of the Amamo Formation.

In addition, prepare a large number of the above-mentioned containers for raising sea eel seedlings and cultivate them, distribute them to multiple households in an arbitrary number, and cultivate eel seedlings in each household as described above. Eels are taken out of the bottles and collected from each household. It is possible to easily cultivate eel seedlings for creation, and it is also possible for ordinary people to participate in the regeneration of eelgrass fields as volunteer activities.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 shows a container (A) for nurturing eelgrass seedlings and for creating eelgrass beds. This is because a woven fabric made of biodegradable polylactic acid fibers is sewn into a box-like container (1), provided at the mouth (2) of this container (1), and with openings (3 ) And a hanging string (5) made of cotton thread is passed through the hollow part (4) and attached to the container (1), and the woven fabric is a plain weave (see FIG. 4). The weave (6) is woven so that it can pass through the roots (8) and rhizomes (9) of the eel (7). A large number of containers (A) for cultivating eelgrass seedlings and eelgrass farms are prepared and distributed in an arbitrary number to a plurality of households to grow eelgrass seedlings in each household. When distributing the eelgrass seedling breeding container and eelgrass farm building container (A) to multiple households, distribute eelgrass seeds, sand and artificial seawater together.

FIG. 2 shows a state in which the seedlings (7a) of the eelgrass have been grown. Specifically, they are grown as follows. That is, a predetermined amount of sand (10) is put into the container (1), seeded with sea eel seeds, and thinly covered with sand (10). Next, put sea water (12) made under artificial seawater into a transparent empty bottle (11) such as instant coffee. Then, submerged in the sea water in the bottle (11) seeded receptor a (1) placed while suspended by seawater (12) hanging cord to the bottle (11) which are satisfied (5), a lid (14 ) And the upper end (5a) of the hanging string (5) is detachably secured with an adhesive tape (13) and the lid (14) is applied to the bottle (11).

  When the seedlings (7a) are sprouting and the seedlings (7a) are nurtured, collect the eellet seedling-growing and eellet container (A) from each household, open the lid (14), and then suspend the string (5 ) And remove the container (1) from the bottle with the hanging string (5). After the eel breeding, the container (A) for nurturing eelgrass seedlings and carrying the eelgrass yard is transported as it is to the sea area for eelgrass lands, and distributed by the divers on the seabed (15) to create eelgrass beds. At this time, a hole for storing the container (1) is dug in advance in the seabed (15).

  Fig. 3 shows that the roots (8) and rhizomes (9) of the eelgrass (7) from the container for nurturing eelgrass seedlings and eelgrass farms (A) after the eelgrass seedlings placed on the seabed (15) ) Through the weave (6) of the plain weave fabric constituting the material (1) and extending into the ground outside the container (1). FIG. 4 shows the details of the state in which the root (8) of the amamo (7) extends out of the container (1) from the weave (6) of the plain woven fabric.

  The container (1) and the hanging string (5) will decompose and disappear in the sea over time.

FIG. 5 shows another eelgrass seedling growing and eelgrass yard building container (B). This is because a synthetic resin made of biodegradable polybutylene succinate adipate is used as a molding material and molded into a pot-like body (16), and a large number of holes that can pass through the roots and rhizomes of the eel. (17) is opened, and a hanging string (18) is attached to the container (16). The method for using the container for cultivating eelgrass seedlings and eelgrass beds (B) is not different from the case of the container for nurturing eelgrass seedlings and eelgrass beds (A).
