Restoration method of shallow-sea sea grass bed

Abstract

The invention relates to a restoration method of a shallow-sea sea grass bed, and belongs to the technical field of production of marine plants. The method includes the steps that kieselguhr, attapulgite and the like are mixed and subjected to ball milling, the mixture is dried and then pressed into round sheets, the circle centers of the sheets are perforated, and high-temperature calcination is conducted to obtain sintered carriers; then, the surfaces of the carriers are coated with self-made sphagnum teres homogenate, culture is conducted in a greenhouse, sphagnum teres is wholly scraped after growing and surviving, sea grass seeds are buried under the sphagnum teres, culture is conducted again to enable the sphagnum teres to grow and be immobilized to the surfaces of the carriers, and breeding sheets are obtained; finally, the breeding sheets are immobilized through nylon ropes and sown in a sea grass restoration area, and conventional sea grass culture is conducted. According to the method, the mode of immobilizing and activating the see grass seeds when the sphagnum teres grows and is immobilized on the surfaces of the carriers of a porous structure is fully utilized, so that seed loss occurring after sowing is avoided; meanwhile, nutrients remaining after the sphagnum teres dies at the seabed can effectively increase the survival rate of the sea grass seeds. Thus, the method has broad application prospects.

Description

technical field [0001] The invention relates to a method for restoring shallow sea seagrass beds, and belongs to the technical field of marine plant production. Background technique [0002] Seagrass beds in shallow seas are feeding grounds, habitats, nursery grounds or shelters for many precious marine organisms such as dugongs, green turtles, and seahorses. The functional value of ecological services is comparable to that of typical marine ecosystems such as coral reefs and mangroves. In addition, seagrass beds also play an important ecological role in promoting silt consolidation, improving nearshore water quality, and maintaining the balance of the global carbon cycle. However, this ecosystem is one of the most fragile ecosystems on the planet. It is lost due to direct or indirect human impacts, and the decline of global seagrass is still accelerating. The accelerated degradation of global seagrass has also led to the deterioration of the coastal ecological environment....

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: Aiming at the problem that the recovery process of the traditional shallow sea seagrass bed is long and the seaweed seeds or plants are lost due to difficulty in fixing, resulting in a low survival rate, a recovery method for the shallow sea seagrass bed is provided
