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.
