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 are few studies on the transplantation technology at the seedling stage

Embodiment Construction

[0036] Such as figure 1 As shown, a method of repairing the Sargassum field, using mesh bags to bind Sargassum seedlings, and placing stones in the mesh bags, throwing them in the sea area of ​​​​the damaged Sargasso field, and the transplanted Sargassum seedlings under natural conditions It grows normally and develops to sexual maturity, realizes the reconstruction of Sargassum populations capable of sexual and asexual reproduction, and promotes the restoration of Sargassum farms.

[0037] The described net bag binding seedling throwing method comprises the following steps:

[0038] (1) Mesh bag preparation: Cut the nylon mesh with a hole diameter of 5cm into 10 pieces of 50cm×100cm, sew it into a mesh bag 3 with one side open with nylon rope, and tie the acrylic digital signage 2 on the mesh bag 3, For future statistics, soak the mesh bag 3 in natural seawater for 1 month;

[0039] (2) Preparation of Sargassum seedlings: During the low tide period in mid-to-late November, ...

Abstract

The invention discloses a method for repairing an intertidal sargasso field. Sargasso seedlings are transplanted and cultivated by adopting a net bag seedling bundling and stone casting method, so that the sargasso seedlings can be subjected to sexual reproduction and asexual reproduction; the net bag seedling bundling and stone casting method comprises the following steps: (a) the sargasso seedlings are fixed in a net bag, and rhizoids of the sargasso seedlings are clung to the net bag; (b) stone is put into the net bag, and the opening of the net bag is fastened and sealed; (c) in a low tide, the net bag obtained in the step b is cast between a low water line of a neap tide and that of a spring tide in an intertidal zone. According to the method, the operation is convenient, a huge matrix does not need to be built, and the consumed fund is little.

Description

technical field [0001] The invention belongs to the technical field of sargassum artificial proliferation and ecological restoration, and in particular relates to a method for repairing a sargassum field in an intertidal zone. Background technique [0002] Large seaweed farms are restorers and stabilizers of the marine ecological environment. Due to environmental pollution and the tense relationship between man and land, the coastline of natural rocky reefs has been severely damaged, and the resources of Sargassum in the lithofacies intertidal zone have been severely depleted, and the ecological functions of Sargassum farms have also been significantly weakened. Many countries in the world have adopted the method of placing a large number of artificial fishing reefs on the seabed to repair seaweed farms, and achieved obvious results, but this repair method requires a huge amount of money and the construction of a huge matrix, which is inconvenient and time-consuming. Force,...
