Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming seagrass beds of eelgrass of marine flowering plants and an effective eelgrass cultivation tool for cultivating and cultivating eelgrass.

[0002]

2. Description of the Related Art Conventionally, there is an increasing need for creating seaweed beds from coastal fishing ground maintenance, environmental compensation / improvement, and natural environment maintenance. Corresponding to these needs, the construction method is different for the garamo or eelgrass fields, depending on the quality of the seabed. In the eelgrass ground, rock wool mats, colloidal silica, and
Non-cultivation soil-inorganized fiber molded bodies, inorganic fiber mats, and other materials such as cotton linen, nylon, and acrylic are sown and cultivated and laid on the seabed, or rhizomes of growing bodies are included in clay blocks and transplanted. Then it is known to create an eelgrass field.

[0003]

However, these methods have various problems. For example, in the case of the former sowing, it is necessary to fix the seeds and to measure the constant layer on the laid seabed. Regardless of how thick the seeds are, the seeds will be pushed into the inside, so it will take a considerable period of time for the buds to grow on the surface layer after germination and rooting and for the mustache roots to settle on the seabed. In addition, some seeds die during this period, which is not efficient. There is also a method of wrapping sand and seeds in a perforated sheet and binding the upper part with a string and sowing directly on the seabed, but this may also interfere with germination, rooting and its growth depending on the position of the hole. Therefore, it is not a preferable method because the fixation on the seabed becomes unstable.

[0004] Especially, it takes a long time for the growth and rooting of the rhizome to grow depending on the sand-mud ratio of the target seabed, the depth, the ocean current, the waves, the topography, etc., and the formation is delayed accordingly, and it is difficult to fix the seeding material during that time. However, there is a limit to laying sowing materials according to the seabed topography, and there are drawbacks such as uneven planting density due to runaway and the like, which is not practical. In the latter method, in which the rhizome of the mature leaves is wrapped in a mud mass and integrated, the mud state changes subtly depending on the water content and the handling method of the mud used, and cracks due to drying over time after integration. In addition to cutting damage to the mustache root, the seabed changes drastically in terms of bottom sediment, topography, depth, waves, seabed current, etc. It is difficult to maintain the shape of the above, and when it is rolled and solidified into a dumpling in a mud mass, it is possible to handle dozens of mature leaf bases collectively, so that the leaf bases are not damaged such as bending. This is not practically possible, which is not desirable because it weakens the algae, and if the sand-mud ratio causes a large amount of mud quality, it is difficult to land on the ship even if it is dropped on the ship or dug at the bottom of the sea. Fluctuations of seafloor topography in the region Outflow accident from it, which is a normally also not be avoided, there is a drawback that hinder the seaweed beds reclamation.

The present invention is intended to easily eliminate these conventional drawbacks. It ensures the rooting of algae roots and mustache roots to promote healthy growth, and is of good quality and has a good yield as eelgrass. It is an object of the present invention to provide a method and a low-cost eelgrass cultivation tool that enables harvesting, is easy to transplant and set up, and that enables the eelgrass field to be constructed at an extremely early stage.

[0006]

According to the present invention, a fiber comprising a calcium-polyethylene composite resin or the like is prepared by wrapping eelgrass leaf bases and / or rhizomes or eelgrass seeds in a sheet or mat of cellulose sponge and binding them together. The seaweed bed is constructed by connecting the knots of the nets and laying the nets on the seabed by means of fixing means such as metal rods, anchors or blocks. The present invention also provides a sheet-shaped or mat-shaped cellulosic sponge encapsulating material capable of wrapping eelgrass leaf root portions and / or rhizomes, and a binding body for converging and binding the edges of the encapsulating material. And a fiber net of a calcium-polyethylene composite resin for connecting and mounting an encapsulant with the bundle.

[0007]

[Function] The sheet-shaped or mat-shaped cellulosic sponge encapsulating material is used as a single sheet or as a combination of two or more sheets, and is wrapped in a form in which the leaf base and / or rhizome of the eelgrass are held inside. From the above, the edges of the encapsulating material are bundled and tied together with a binding body, which is laid on the seabed of the seaweed bed creation, ideal for landing growth bodies in neighboring waters, and has good vitality,
Protects eelgrass leaf roots and rhizomes against external forces that may be lost due to submarine currents, transported, or submerged in seawater, ensuring reliable and quick rooting in seabed sand mud without damaging algal grass bodies. Can be made. Further, since the encapsulating material is connected and attached to the knot of the fiber net of the calcium-polyethylene composite resin with the above-mentioned binding body, the encapsulating form can be maintained and the encapsulating material is biodegraded by seawater to cause the root stem to grow. The roots and whiskers can be easily rooted without interfering with the growth of the roots, can be fixed to the fiber net, and can easily enter the seabed sand mud to increase the position fixing function, and there is no risk of outflow due to seabed flow. The encapsulant is biodegradable and does not pose a problem to the natural environment. Further, the fiber mat is effective for growing eelgrass by simply laying it with a metal rod, an anchor or a block, and it is easy to relocate and install the seaweed bed, and it can be adapted to the geological condition of the seabed.

However, these methods have various problems. For example, in the case of the former sowing, it is necessary to fix the seeds or to settle the seeds on the laid seabed. However, since the seeds are pushed into the thick ones, it takes a considerable period of time for the shoots to grow on the surface layer after germination and rooting and for the beard roots to settle on the seabed. In the meantime, some seeds die and the efficiency is not good. There is also a method of wrapping sand and seeds in a perforated sheet and binding the upper part with a string and sowing directly on the seabed, but this may also interfere with germination, rooting and its growth depending on the position of the hole.
