Gulfweed proliferation and transplanting method

The invention relates to a gulfweed proliferation and transplanting method. The method aims at the current conditions that the gulfweed resources seriously decay, and the marine ecology is damaged in the prior art, the proper gulfweed types and the sea region and intertidal zones suitable for the gulfweed to live and grow are screened, a round-table-shaped or trapezoidal cube artificial concrete attaching medium is utilized, sexual reproduction gulfweed juvenile sporophytes are used as seedling sources, the seedling sources are bound onto attaching medium grooves by a seedling clamping rope to be placed into the sea region, or fast curing cement is used for fixing the attaching medium subjected to the seedling attachment onto natural reefs based on the original ecology, the gulfweed proliferation and transplanting is carried out for recovering the natural gulfweed resources and protecting the coastal ecological environment, and the basic resources are provided for the marine ecology recovery. An artificial gulfweed field built by the method can be used for generational population reproduction, and the technical support is provided for the building of large-scale seaweed field and the marine ecology recovery.
