Method for building sargassum bed in artificial riprap shoreline by adopting adhered algal reef

Abstract

The invention discloses a method for building a sargassum bed in an artificial riprap shoreline by adopting an adhered algal reef. The method for building the sargassum bed in the artificial riprap shoreline by adopting the adhered algal reef comprises the following steps: (1) collecting sargassum seedlings, with complete forms, with rhizoid attached onto shells on intertidal zone rock; (2) selecting stone, and fixing the shells to which the sargassum seedlings are attached to surfaces of the stones with an adhesive to produce the algal reef; (3) placing the algal reef in middle and low intertidal zones of the riprap shoreline, making the algal reef fixed among riprap, ensuring that the sargassum seedlings on the algal reef face upwards or are arranged towards waves, and conducting sea area cultivation; and (4) conducting sea area cultivation to make the rhizoid of the sargassum seedlings ramble and attached onto the surfaces of the stone for the second time, and conducting vegetativepropagation to regenerate a large amount of new seedlings to make sargassum reproduce on the riprap shoreline, so as to achieve building of the sargassum bed. According to the method, by adopting theproduction method of the adhered algal reef, the natural sargassum seedlings are transplanted into the artificial riprap shoreline area, the method is easy for large-area application and popularization, and is convenient to operate and low in cost, and the labor intensity is low.

Description

technical field [0001] The invention relates to a method for constructing a seaweed field on an artificial riprap shoreline by using sticky algae reefs, and belongs to the technical field of marine ecological environment restoration. Background technique [0002] Large seaweed farms are restorers and stabilizers of the marine ecological environment, and are habitats, breeding grounds, and feeding grounds for marine organisms. Therefore, constructing a sargassum field on the artificial riprap shoreline can reduce the continuous deterioration of the coastal ecological environment. Many countries in the world have adopted the method of putting a large number of artificial fishing reefs in the intertidal zone to build seaweed farms, and achieved obvious results. However, this construction method requires a huge amount of money and a huge substrate, which is inconvenient and time-consuming. It is labor-intensive and destroys the sea area landscape, and is not suitable for bedroc...

Problems solved by technology

At present, the proliferation and transplantation technology based on the sexual reproduction of seaweed is widely used, but this technology is limited to the reproductive season of the algae, and there is little research on the transplantation technology at the seedling stage, and the quick-setting cement, epoxy glue, silicon Direct sticking methods such as clay brick glue have a certain toxic effect on transplanted seaweed seedlings, resulting in slow growth of transplanted seedlings, low survival rate, and inability to reproduce the population
