Manual seaweed transplanting method and reef used for transplanting seaweed

Abstract

The invention relates to a manual seaweed transplanting method and a reef used for transplanting seaweeds, and belongs to the technical field of marine ecology. The manual seaweed transplanting method comprises the following steps: firstly manufacturing a reef formed by a reinforcing steel base and a dome-shaped algal reef matrix, wherein the surface of the algal reef matrix is provided with a rough surface beneficial for adhesion of seaweed spores; cultivating small reef blocks adhered with the seaweed spores in a laboratory, wherein the surface of small reef blocks are rough; and then transplanting the small reef blocks to preformed holes in the algal reef matrix, placing the algal reef matrix transplanted with the small reef blocks with a lifting rope to the seabed requiring to be transplanted with seaweeds, and making the seaweeds grow in the natural environment. According to the invention, the dome shape of the algal reef matrix is favorable for preventing sediments in seawater from accumulating on the algal reef to block the adhesion of the seaweed spores, and can efficiently disperse the impact of sea waves so as to enhance the wave resistance of the algal reef matrix and make the transplanting ration of the reef higher. A large scale of reefs, which are transplanted according to the transplanting method provided by the invention, can form a stable and durable algal reef group on the sea bed so as to successfully build a manual seaweed field.

Description

technical field [0001] The invention relates to a seaweed artificial transplantation method and a reef body used for seaweed transplantation, belonging to the technical field of marine ecology. Background technique [0002] In the near-shore rocky bottom sea area, some places have natural seaweed growing, and some places have no natural seaweed growth due to factors such as tide, light, and nutrient distribution. Because seaweed provides habitat for seabed fish, it plays an important role in the marine ecological environment. For this reason, relevant personnel consider artificial seaweed transplantation in places where there is no natural seaweed growth, in order to achieve the purpose of repairing seaweed fields, improving the marine ecological environment, and providing habitats for seabed fish. [0003] At present, there are plug-in algae reefs and their methods of constructing algae fields, which are used to put various shapes of algae reefs on the seabed to realize th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects in the process of transplanting algae reefs in the above-mentioned prior art, and provide a method for artificially transplanting algae reefs, to carry out artificial seaweed transplantation to those places where there is no natural seaweed growth, and use the algae The reef transplanting method makes the algae reef transplant stable, has good wave resistance performance, and has a good transplant effect. It can well repair the seaweed field, increase the seaweed coverage rate, and provide a habitat for seabed fish.
