Embodiment Construction

[0014] The present invention will be further described in detail by examples below, and these examples are only used to illustrate the present invention, and do not limit the scope of the present invention.

[0015] In the mature period of Gliconia constricta (the period containing fruit sporophytes and tetrad sporophytes), select the seaweed field of Gliconia constricta that has the advantage of growing under natural conditions, and the laying size is 5×20m 2 Lay bamboo piles around the tiled mesh, the bamboo piles are 0.4-0.6 meters, the bottom is sharpened, drive into the seabed every 5m around the mesh, and fix the mesh with polyethylene rope to prevent the net The pieces are washed away or folded by sea water;

[0016] Mature Gracilaria constricta releases spores and subsides, and the released spores will attach to the mesh in large quantities (artificial attachment base). After the spores grow under natural conditions to the stage where discs or erect branches begin to f...

Abstract

The invention relates to a method for restoring a degenerated algae field by using gracilaria macro-algae namely gracilaria salicornia, and belongs to the technical field of marine ecological environment restoration. According to the method, a natural gracilaria salicornia algae field with high-quality growth vigor is selected in the period when gracilaria salicornia are mature and release generative cells, a mesh with a specification of 5*20m<2> is laid at the bottom of the algae field to provide an appropriate adhering substrate for spores, and after collection of the spores and when the spores grow naturally to have discoidal bodies or in the stage of formation of erect branches, and the mesh with gracilaria salicornia seedlings is transplanted to an algae restoration area to ensure that gracilaria salicornia populations can be enlarged in a partially degenerated algae field or stable gracilaria salicornia populations can be reestablished in a completely degenerated algae field, thereby achieving ecological restoration of a gracilaria algae field. By adoption of the method, a germplasm source is provided for a restored area, and a degenerated algae field can be effectively restored.

Description

technical field [0001] The invention relates to a method for repairing a degraded seaweed field, in particular to a method for repairing a degraded seaweed field by a large seaweed of the genus Gracilaria, Gracilaria pendenta, and belongs to the technical field of restoration of the marine ecological environment. Background technique [0002] Seaweed farm is a kind of unique ecosystem formed by macrobenthic seaweed as supporting organisms, which has the characteristics of large biomass, high productivity and long life cycle. It can absorb nitrogen and phosphorus, enrich metal ions, and has a good purification and ecological restoration effect on coastal waters. [0003] In recent years, due to the irrational economic activities of human beings, the rapid development of modern industry and marine aquaculture, the offshore environment has been seriously polluted, and the diversity of aquatic ecosystems has been destroyed. Furthermore, global climate anomalies have also led to...
