Problems solved by technology

[0004] The existing artificial algae field construction method mainly adopts the transplanting of wild algae bodies, such as binding with nylon cable ties. This kind of algae reefs has certain damage to natural resources and cannot be widely promoted, and the survival rate of damaged seedlings is low. high

Embodiment 1

[0036] The specific method of constructing the Sargassum artificial algae field is as follows:

[0037] 1. Design and treatment of artificial algal reefs

[0038] In order to ensure the effectiveness of the construction of the algae field and the convenience and quickness of the operation, the design of the artificial algae reef is as follows: figure 1 as shown, figure 1 Among them, 1 is an artificial algae reef, 2 is a groove, and 3 is a brick attachment base.

[0039] The cuboid artificial algae reef is built according to the mass ratio of water: cement: sand: stone = 0.5:1:1.8:3. The dimensions of the cuboid are: length 60 cm, width 50 cm, height 30 cm. On the upper surface of the cuboid artificial algae reef (50 cm × 60 cm), there are 6 inlaid grooves left during casting. The dimensions of the grooves are 13 cm long, 7 cm wide and 13 cm deep.

[0040] 2. Treatment of artificial algal reefs

[0041] Select the low tide level of the hard intertidal zone suitable for the...

Embodiment 2

[0057] With long 80 cm, wide 45 cm, the reef base of high 35 cm, adopt half-leaved Sargassum seedlings as an example to further illustrate the present invention:

[0058] 1. Design and treatment of artificial algal reefs

[0059] The reef is a concrete algal reef with a length of 80 cm, a width of 45 cm and a height of 35 cm. On the upper surface of the cuboid artificial algae reef (30 cm × 80 cm), there is a long mosaic groove during casting. The size of the groove is 15 cm long, 7 cm wide and 13 cm deep.

[0060] 2. Treatment of artificial algal reefs

[0061] Select a low-tidal zone with a hard substrate suitable for the natural growth of Sargassum half-leaf, put the newly constructed artificial algae reef into the selected restoration sea area two weeks in advance, and use seawater soaking to remove the alkaline substances in the cement.

[0062] 3. Selection of Sargassum attachment base

[0063] The selection specifications of the Sargassum attachment base are: 22 cm i...

Embodiment 3

[0071] With long 60 cm, wide 50 cm, the artificial algae reef of high 30 cm, adopt half-leaved Sargassum seedlings as an example to further illustrate the present invention:

[0072] 1. Design and treatment of artificial algal reefs

[0073] The dimensions of the artificial algae reef are: length 60 cm, width 50 cm, height 30 cm. On the upper surface of the cuboid artificial algae reef (60 cm × 50 cm), there are three inlaid grooves left during casting. The dimensions of the grooves are 14 cm long, 9 cm wide, and 18 cm deep.

[0074] 2. Treatment of artificial algal reefs

[0075] Select a low-tidal zone with a hard substrate suitable for the natural growth of Sargassum half-leaf, put the newly constructed artificial algae reef in the selected algae farm construction area two weeks in advance, and use seawater soaking to remove the alkaline substances in the cement.

[0076] 3. Selection of Sargassum attachment base

[0077] Similarly, the specification of the attachment ba...

Abstract

The invention relates to a method for constructing a sargassum artificial algal field through an inlay method. The method comprises the following steps that S1, an artificial algal reef is constructed, and the top end face of the artificial algal reef is provided with grooves matched with bricks in shape; S2, by the adoption of an artificial seedling breeding mode, the bricks are adopted as substrata, seedlings are attached to the bricks in an artificial room for semi-flowing water cultivation, and then flowing water is adopted for cultivating fry; S3, a low-tide zone just breaking the surface of water when a spring tide ebbs is selected to serve as a restoration zone, and the artificial algal reef constructed in S1 is put in sea water in a to-be-restored area to be soaked for two weeks or more; S4, the brick substrata obtained in S2 are vertically inlaid in the artificial algal reef treated in S3 in the long-axis direction, the sides with the seedlings are outward, and accelerated cement is poured in gaps. According to the method for constructing the algal field, the seedling substrata and the artificial algal reef are operated separately, and the survival rate of sargassum is raised beneficially; moreover, the artificially cultivated seedlings are adopted as a seedling source for restoration of the algal field, and accordingly original natural algal resources cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of sargassum artificial proliferation and marine ecology, and in particular relates to a method for constructing a sargassum artificial algae field by a mosaic method. Background technique [0002] Due to the interference of human activities, sea area pollution, water eutrophication, coastal land reclamation and the implementation of coastal projects, the ecological environment of algae has changed, and a large number of natural algae fields have degraded and disappeared. The coastal environment and sea water quality, and the restoration of large seaweed algae fields have received attention and attention from all sides. [0003] Sargassum is a large economical algae, which can extract a variety of active ingredients and is an important raw material for the production of seaweed fertilizer. The extracted alginate is an important raw material for the food industry. The sargassum algae field can be a place for...
