Description

  The present invention relates to a laver seed seeding method for laver net seeding (land seedling seedling) with a laver seed on land, and a laver net seeding device used in the method.

  As a conventional method for seeding seaweed (land seedling seedling) on a laver net on land, a method using a waterwheel-like rotating frame (commonly referred to as “waterwheel”) described in Non-Patent Document 1 or Non-Patent Document 2 is used. Are known. This conventional method for seeding a seaweed net is to prepare a seeded water tank for seeding (hereinafter also referred to as a water tank) and a large curing water tank for curing, and a diameter of about 1.6 to 3 m on the water tank. A waterwheel-like rotating frame (commonly called “waterwheel”) is provided so that it can rotate, and around September-October when the water temperature falls, generally around 18m (called a 10-nosed laver net) ) Repeatedly wrapping a long laver net with a length of about 2-4 turns from one end to the end while winding the required number of sheets, for example about 150, on the outer periphery of the rotating frame. Prepare.

  Next, put the oyster shell thread into the aquarium, and the drive motor with the rotating frame immersed in the seawater in the aquarium in the time zone (morning) when the shell spores emerge from the oyster shell filament The shell spores (nori species) floating on the seawater surface are attached to the fiber surface of the laver net by repeatedly rotating. The rotation frame is rotated for a required time, for example, about 10 minutes. When the number of shell spores adhering to the laver net is observed with a microscope and the number reaches a desired number, for example, about 50 under a microscope with a 100 × field of view, , And unwind and remove the required number of laver nets, for example, about 10 to 12 on the outside, and carry the removed laver nets to a large curing aquarium separately installed, and the curing aquarium The shell spore adhering to the laver net is cured and fixed on the laver net. In addition, after the nori mesh is removed, the rotating frame is rotated again to attach shell spores to the nori net on the outer periphery of the next rotating frame. Thereafter, the same operation is repeated, and all the nori nets wound around the rotating frame are applied. After attaching the shell spores, the shell spores are fixed on the laver net in the curing tank.

  In a conventional method for seeding a laver net in a land-based seedling, for example, about 30 m while a long laver net with a length of about 18 m is wound about 2 to 4 times around the outer periphery of a rotating frame with a diameter of about 1.6 to 3 m. ~ 100 sheets of nori mesh are wound around a rotating frame, and the rotating frame is rotated so that shell spores (nori seeds) are attached to the fiber surface of the nori mesh, so one sheet wound around the rotating frame In the laver net, the outer peripheral layer of the shell spores (seaweed species) that are relatively easy to adhere and the inner peripheral layer that is relatively difficult to adhere occur, and the shell spores (nori seeds) adhere to the single laver net There is a problem that spots are produced in the degree, and the laver seedling and plucking workability in the later process is deteriorated. Also, if the desired number of shell spores adhere to the fiber surface of the laver net by rotating the rotating frame, the required number of laver nets outside the shell spores are unwound and removed, and the removed laver net is installed separately. The shell spore is placed in the seawater of a large curing tank for a long time (generally about 5 hours) to fix the shell spore. When transporting the net to the curing tank, the shell spores attached to the laver net fall due to rubbing the laver net, and the number of settled shell spores on the laver net decreases, resulting in poor laver productivity, There is a problem that spots occur in the colonized state of shell spores. In addition, the laver net removed from the rotating frame is put in the seawater of a large curing tank for several hours to fix the shell spores to the laver net, so if sunlight hits the laver net being cured in the curing tank only from above. However, since the spots appear on the curing, it is necessary to turn the laver net upside down, and it takes a lot of manpower and time to cure the laver, and the work time is increased, and a large curing tank is installed. There is a problem that needs to be large and expensive.

It is practical to provide a plurality of rotating frames corresponding to each water tank so that the lower part thereof faces the water tank so that the plurality of rotating frames are stably rotated by the rotating base frame. For example, a total of six aquariums are arranged side by side on the left and right, and a rotating base frame lying above each of the left and right aquarium groups is rotatably provided, and the outer peripheries of these rotating base frames correspond to the respective water tanks. Three rotating frames may be provided so that the lower part faces the corresponding water tank. In addition, the length of the laver net used in the seaweed aquaculture industry is generally about 18-19m (it is said to be between 10), so the diameter of the rotating frame should be about 6-8m. It can cope with general laver nets.

The laver net seeding device 1 includes a rectangular water tank 2 for containing seawater and oyster shell filaments. The aquarium 2 is fixedly installed with concrete or the like by opening an installation space 3 in the center and separating the water tank 3 from left to right. The water tank 2 may be configured by a box such as a metal plate. On one end side of the water tank 2, a net attachment / detachment work table (work floor) 4 higher than the upper end of the water tank 2 is provided. Each water tank 2 is provided with a cold water supply device, a cold / hot water supply device, a tank temperature indicating controller and a drainage device, which are not shown in the figure, and automatically detects the seawater temperature in each water tank 2 to supply cold water and hot water. By controlling the discharge of seawater and seawater, the seawater temperature in each tank 2 can be automatically managed automatically. A support base 7 is installed in an installation space 3 between the water tank groups 2 </ b> A of the water tanks 2 provided on the left and right, and a bearing frame 8 is fixed to the support base 7. In addition, bearing frames 9 are erected on the left and right side positions of the two water tank groups 2A.

Above each water tank 2, a rotating frame 10 for winding a laver net is rotatably arranged with its lower end facing the water tank 2. The three rotation frames 3 corresponding to the three water tanks 2 on the left side and the three water tanks 2 on the right side are provided on the outer periphery of the rotation base frame 13 fixed to one rotation shaft 12, respectively. A forward and reverse rotation is integrally performed by a later-described transmission motor 40 installed on the base 7.
The pair of left and right rotating base frames 13 includes a pair of left and right square boss members 15 fixed to a rotating cylinder 14 having a large diameter (for example, about 270 mm) fitted to the rotating shaft 12, and each side portion of both boss members 15. 4 pairs of rim members 16 that are joined together so that the base portion is fixed to the end portion and the tip portion forms a triangle, and the tip portion of each rim member 16 so that the rotation shaft 12 is at the center. A pair of left and right annular base frames 17 fixed to each other, and a connecting frame fixed in a bridging manner to the pair of left and right annular base frames 17 at positions that equally divide the circumference of the annular base frame 17 into a large number (16 in the figure) The annular base frame 17 is connected between a position where the periphery of the annular base frame 17 is equally divided into a plurality (4 in the figure) and a mounting plate 19 fixed to the middle part of the length of the rotary cylinder 14. And a plurality of turnbuckle members 20 that are supported so as not to move left and right. There. The boss member 15 is composed of a stainless steel flat plate, and the rim member 16, the annular base frame 17, and the connecting frame 18 are firmly composed of stainless steel pipe members having a relatively large diameter (for example, a diameter of 60 mm). Each boss member 15, rim member 16, and annular base frame 17 may be provided at an intermediate portion of the rotating cylinder 14 as needed to reinforce the intermediate portion of the connecting frame 18.

Each rotating frame 10 is fixed to a large number of U-shaped support frames 21 fixed to the respective connecting frames 18 of the annular base frame 17, and to the inner sides of both corners of these U-shaped support frames 21, respectively. A pair of left and right annular frames 23 supported on the outer peripheral side of 17 and a bridging shape between the pair of left and right annular frames 23 at positions where the periphery of the annular frame 23 is equally divided into a large number (32 in the figure). The connecting rod 25 is used for winding the seaweed net, and a plurality of positioning members 26 for restricting the net position that are fixed to both ends of each connecting rod 25 and project to the outer peripheral side. The connecting rod 25 is constituted by a connecting member 25a fixed in a bridging manner to a pair of left and right annular frames 23 between the connecting portion 21a of the U-shaped support frame 21 and each connecting portion 21a. The U-shaped support frame 21, the annular frame 23, the connecting rod 25, and the positioning member 26 of the rotating frame 10 are made of stainless steel relatively small diameter rods (for example, 16 mm in diameter), and nori to be wound around the rotating frame 10. Sunlight is not cut off from the net W as much as possible. The diameter of the annular frame 23 of the rotating frame 10 that determines the outer peripheral length of the rotating frame 10, that is, the outer peripheral length of the annular frame 23, is such that the outer peripheral length of the annular frame 23 is larger than the length of the laver net W to be wound. It is set much larger than the conventional device. In general, the length of the laver net W used in the seaweed culture industry is about 18 to 19 m (which is said to be between 10), so the diameter of the annular frame 23 of the rotary frame 10 is about 6 m or more. Is set to For example, when the length of the laver net W used for nori cultivation is about 19 m, the diameter of the annular frame 4 of the rotary frame 3 is set to about 6 m. Although the upper limit of the diameter of the annular frame 23 is not limited, practically, if the length is about 8 m, it is sufficient because the length of the laver net W is about 25 m.
The rotary shaft 12 is rotatably supported by a pair of bearings 30 and 31 that are attached to the bearing frames 8 and 9, respectively. A chain wheel 33 is wedged on the rotary shaft 12, and the chain wheel 33 is rotated via a drive wheel 34 and a chain 35 by a speed-reversible motor 40 installed on the support base 7. Yes.

Next, the seeding method to the laver net W which seeds shell spores on the fiber surface of the laver net W using the laver net seeding device 1 will be described.
The seeding (seedling) on the laver net W is generally performed from September to October when the seawater temperature falls. In addition, shell spores are released from the oyster shell filaments for about two hours in the morning when sunlight begins to hit, so they are concentrated in the morning with good seeding conditions. Therefore, by the morning of the seeding day, the oyster shell filaments are managed so as to easily release shell spores, and the conditions suitable for seeding in each tank 2 (for example, temperature 18 degrees C to 23 degrees C, specific gravity 18 or more) , PH 7.5 to 8.3) seawater is put in and managed so as to maintain the state, and oyster shell filaments are put in the seawater of the water tank 2. Further, on the day before the seeding date, a required number of laver nets W, for example, about 50 sheets are wound around the outer periphery of each connecting rod 25 row that is the outer periphery of each rotary frame 10. In the winding of the laver net W, the diameter of the annular frame 23 of the rotary frame 10 is set to about 6 m so that the outer circumference of the rotary frame 10 is longer than about 18 m of the length of the laver net W. The nori net W is wound around the outer periphery of the rotating frame in a single layer without overlapping, and about 50 sheets of nori net W are sequentially wound around the outer periphery of the rotating frame 10 (the portion where the nori net W is not wound). Wrap in a single line while shifting in the outer circumferential direction. Since the lower end of the rotating frame 10 faces the water tank 2, the lower part of the laver net W wound around the outer periphery of the rotating frame 10 is immersed in the seawater in the water tank 2.

  After confirming that sunlight has started to hit and spore spores have started to emerge from the oyster shell filaments, or before that, the rotating shaft 12 is rotated in one direction (the laver net winding direction) by the speed change motor 40 and left and right 3 The rotating frames 10 are simultaneously rotated. The laver net W wound around the rotary frame 10 by the rotation of the rotary frame 10 is rotated with the lower part immersed in the aquarium 2, and as a result, the shell spores floating in the seawater in the aquarium 2 are One after another adheres to the surface. In this case, since each laver net W is wound around the outer periphery of the rotary frame 10, spore spores are uniformly attached to each laver net W under the same conditions, and the total length of the laver net W is increased. The adhesion spots of the shell spores can be eliminated. Moreover, since each rotation frame 10 is provided in the outer periphery of the strong rotation base frame 13, each rotation frame 10 with a large diameter can be rotated stably.

  For example, when the rotation of the rotary frame 10 is performed for about 15 minutes, the number of shell spores attached to the outer peripheral surface of the laver net W wound around the outer periphery of the rotary frame 10 is observed with a microscope, and the number is 100 times. When the desired number is reached, for example, about 50 under the microscope in the field of view, the rotation of the rotary frame 10 by the speed change motor 40 is stopped, and the oyster shell filament is taken out of the water tank 2. In the state where the oyster shell filaments are taken out, a desired number of new laver nets W to be seeded next, for example, about 50 new laver nets W are again seeded on the laver net W on the outer periphery of the rotary frame 10 in the same manner as above. Wrap to be single. After that, with the oyster shell thread or a new oyster shell thread in the water tank 2, the rotating frame 10 is rotated again in the same manner, and a new laver net W wound around the outer periphery of the rotating frame 10 is formed. The number of shell spores adhering to the outer peripheral surface of the laver net W was observed with a microscope when the shell spores were attached to the outer peripheral surface and the rotary frame 10 was rotated for about 10 minutes, for example, and the number was 50 as described above. Then, the rotation of the rotary frame 10 is stopped again, and the oyster shell filament is taken out of the water tank 2 and the desired number of seeds to be seeded next on the laver net W to which the shell spores are adhered, for example, about 50 new ones. The laver net W is wound so that each laver net W becomes a single layer as described above. After that, with the oyster shell thread or a new oyster shell thread in the water tank 2, the rotating frame 10 is rotated again in the same manner, and a new laver net W wound around the outer periphery of the rotating frame 10 is formed. The number of shell spores adhering to the outer peripheral surface of the laver net W was observed with a microscope when the shell spores were attached to the outer peripheral surface and the rotary frame 10 was rotated for about 10 minutes, for example, and the number was 50 as described above. The rotation of the rotary frame 10 is stopped when the degree is reached. As a result, the required number of shell spores are uniformly attached to the surface of the fibers of about 150 laver net W wound around the outer periphery of the rotary frame 10.

Thereafter, the oyster shell filaments immersed in the seawater of the aquarium 2 are taken out of the aquarium 2. In a state where the oyster shell thread-like body is taken out from the water tank 2, the rotary frame around which the laver net W is wound is rotated for a required time, for example, about 2 hours. As a result, the shell spores attached to the laver net W are stimulated by receiving sunlight and seawater alternately, are cured into healthy shell spores, and are fixed to the laver net W. In this case, each laver net W wound around the rotating frame 10 is wound around the outer periphery of the rotating frame 10 of a hollow annular frame formed of a relatively thin rod-shaped material, so that sunlight is nourished. It sufficiently hits both sides from the inside and outside and the side of the net W, so that the shell spores are efficiently cured and the shell spores are fixed on the laver net in a short time. After the spore spores are fixed on the laver net W, the rotating frame 10 is rotated in the reverse direction to remove the laver net W from the rotating frame 10 and drain the water. Save with.
The laver net seeding device 1 shown in the drawing includes a total of 6 rotating frames 10 on the left and right sides, so that it can be seeded on a total of about 1000 laver nets W per day.
Note that the number of laver net W wound around the rotary frame 10 at a time is not limited to about 50, and may be arbitrarily changed as necessary. In addition, the number of times the desired number of laver nets W are wound around the rotating frame 10 and the shell spores are attached is not limited to 3 times, and may be changed to any number. The number of windings of the net W may be different from each other. Further, the laver net seeding device is not limited to a connected type device in which a plurality of rotating frames are rotated by one rotating shaft, but is rotated by one rotating frame by one rotating shaft. Needless to say, it may be constituted by a single device.

It is a front view of the laver net seeding device used for the laver seed seeding method to the laver net. FIG. 2 is a side view showing a part of FIG. 1 in cross section. It is a top view of FIG. It is the IV-IV sectional view taken on the line of FIG.
