Sargassum horneri seaweed bed human-induced restoration device and restoration method thereof

Abstract

The invention provides a sargassum horneri seaweed bed human-induced restoration device which comprises a secondary reef, an intermediate incubator and a primary reef, wherein the intermediate incubator comprises a protection body and a base; a cylindrical groove is formed in the center of the top surface of a base; the diameter of the protection body is the same as the diameter of the secondary reef and the inner diameter of the groove of the base; the secondary reef is arranged between the protection body and the base by virtue of the intermediate incubator; and the shape of the primary reef refers to two asymmetric triangular inclined surfaces which are connected with each other and are provided with connecting bolts and permeable holes. The invention also provides a sargassum horneri seaweed bed human-induced restoration method. The method comprises the following steps: performing seedling collection on the secondary reef, performing workshop cultivation, then cultivating in the intermediate incubator with a low tidal region between tides, fixing the secondary reef on the primary reef, and throwing into the seabed target restoration position. According to the device and method disclosed by the invention, the healthy and strong degree of seedlings can be enhanced, the probability of seedling removal is effectively reduced after the seedlings are put into the sea, and the survival rate of the seedlings at the seabed is improved; and moreover, the secondary reef is convenient to mount and detach, and even if the secondary reef is put into the seabed along with the primary reef, the secondary reef can be manually taken down, and later tracing observation is conveniently realized.

Description

technical field [0001] The invention belongs to the field of seaweed bed restoration, and in particular relates to a copper alga seaweed bed artificial repair device and a repair method. Background technique [0002] Copper algae is a class of brown algae with economic value. It is not only edible, but also used as raw material for alginate extraction in industry. It is also used in the field of biomedicine because it contains biologically active substances such as fucoidan and polyphenols. Copper algae also has important ecological value. It has strong biosorption capacity for heavy metals (nickel, cadmium, etc.) and eutrophication substances (nitrogen, phosphorus, etc.) in seawater, and can be used as a tool seaweed to restore the offshore ecological environment. In nature, copper algae usually gather in clusters to form nearshore seaweed beds, which are an important part of the offshore marine ecological environment and provide foraging and habitat for offshore economic f...

Problems solved by technology

However, cultivating seedlings in the workshop will lead to weakening of the seedlings' vigor. After being placed on the seabed, they are prone to phenomena such as poor attachment and seedling removal. Moreover, the cultivation in the workshop requires hydropower and manpower, which has high economic costs.

In short, the seabed survival rate of seedlings using the current repair method is not high, so a device and method that is easy to operate and suitable for the seabed proliferation of copper algae is needed
