Abstract
The invention relates to an artificial sea-grass field which is characterized by comprising a net cage; the net cage is provided with a seashell; an iron mesh is wrapped on the net cage; a fixed cable is arranged outside the iron mesh. During construction, sea-grass seeds are introduced to the seashell or a PE rope and wound on the net cage; the cable is used to levelly lay the net cage and fix the net in the depth of the sea. The price of the construction materials used by the invention is low, the raw materials are easily available, the operation is convenient, and the depth of the prior sea which is not suitable for the sea-grass to grow is improved, so that the depth of the sea is suitable for the sea-grass to be attached and grow. In the construction method, large sea-grass seedlings are introduced artificially, so that the construction success rate of the sea-grass field is high. The artificial sea-grass field can effectively prevent the eutrophication of sea areas, improve the water quality and restore the ecological environment of the sea areas; meanwhile, the sea-grass itself is the bait of marine organisms and the place of activities and egg laying, which can improve the biological diversity index of the sea areas.
Description
Technical field
The present invention relates to a kind of artificial algae field and construction method thereof.
Background technology
In recent years, offshore sea waters eutrophication degree is serious, the ecotope disequilibrium in sea area, and red tide takes place frequently.In addition, overfishing causes the value volume and range of product of coastal region fish to reduce day by day, and fishery resources are subjected to heavy damage.Tangleweed is restoration of the ecosystem person, the person of stablizing of marine environment.But in the coastal waters and culture the sea area, some substrate condition is not suitable for the growth of tangleweed, has influenced marine organisms and has taken the photograph bait and lay eggs.Improving the substrate condition in these sea areas in this case by artificial mode, introduce tangleweed, make up " artificial algae field ", set up the comprehensive ecological cultivation system, is urgent problem.
For natural " oceanic pasture " is provided to marine animal, reach the purpose of repairing the fishery ecotope, need carry out the structure of artificial algae field.And the artificial algae field of people's structure is fairly simple extensive at present, as throwing in stone, cement block or cement plate etc., relies on marine alga self-sow thereon.The structure shortcoming of this artificial algae field is that used raw-material weight is big, the labour intensity height; On the silt in pond covers easily, make marine alga be difficult for growth, even cause marine alga death.Simultaneously, the extract of cement also can cause to a certain degree pollution to water quality, is unfavorable for that tangleweed adheres to, and does not more have specific aim to introduce suitable tangleweed, thereby causes the algae field to make up failure easily.
Summary of the invention
The purpose of this invention is to provide a kind of artificial algae field and construction method thereof, it can remedy the above-mentioned deficiency of prior art effectively.
A kind of artificial algae field is characterized in that having a cylinder mould, and shell is housed in the cylinder mould, cylinder mould external application wire netting parcel, and wire netting has fixedly hawser outward.
The construction method of above-mentioned artificial algae field is characterized in that earlier shell being packed into the cylinder mould the inside, then the marine alga seed is introduced on the cylinder mould, and cylinder mould external application wire netting parcel is fixed in the seabed with hawser with the cylinder mould tiling.
Structure material price used in the present invention is cheap, and raw material is easy to get, and is easy to operate, and can improve the former seabed that is not suitable for marine alga growth, makes it be suitable for marine alga and adheres to and grow.Construction method adopts manually introduces the tangleweed seedling, thus make the algae field be built into the power height.The present invention can prevent and treat the sea area eutrophication effectively, improves water quality, repairs the ecotope in sea area; Sheng Chang marine alga itself is halobiontic bait and movable spawning place simultaneously, can increase the biodiversity index in sea area like this.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Embodiment 3, fill oyster shell 2 in advance in cylinder mould 1, and cylinder mould 1 external application diameter is that 2mm, mesh are that wire netting 3 parcel of 2.0cm is tight.Directly gather the autumn spore seedling of marine alga-undaria pinnitafida on the cylinder mould 1 with wire netting 3 parcels, indoor cultivation one month, the seedling for the treatment of to be become by the undaria pinnitafida spore development was fixed on the seabed with the hawser 4 of cylinder mould 1 usefulness diameter 1.0cm after growth on the cylinder mould 1 is firm.
Embodiment 5, fill scallop shell 2 in cylinder mould 1, and cylinder mould 1 external application diameter is that 2.5mm, mesh are that wire netting 3 parcel of 2.0cm is tight.Marine alga-petrochemical industry dish branch is rived, tightly be wrapped on the 1.5cm polyethylene rope, this polyethylene rope is wrapped on the outer wire netting 3 of scallop cage cylinder mould 1 again, be fixed on the seabed with the hawser 4 of diameter 2.0cm.
Marine alga of the present invention comprises brown alga, red algae and green alga.
