Embodiment 1

[0024] Using the method of the present invention to carry out the transplantation of eelgrass and the recovery and rebuilding test of seagrass bed in a bay in Shandong. The materials used are as follows: ① Thin cotton rope (2 mm thick, placed in seawater, degraded after three months at 20 ° C); 120 grams), the surface of the stone is relatively rough; ③ fresh and alive eel plants, collected in the natural sea area, cut off the crown of eel, so that the height of eel is 20 cm.

Abstract

The invention relates to seaweed bed restoration and reconstruction techniques, in particular to a simple and convenient zostera marina L. seaweed bed ecological restoration system, which comprises: fixing zostera marina L. on stones of proper sizes by thin ropes; and performing zostera marina L. cultivation and seaweed bed ecological restoration in a proper sea area, wherein the cultivation density of the zostera marina L. is 300 to 500 plants per square meter. When the method is used, the problem that the high water power of an intertidal zone affects the cultivation and survival of seaweeds and the problem that it is difficult to transplant seaweed in the sea area in a subtidal zone are solved, and the restoration or reconstruction of the zostera marina L. seaweed beds in the intertidal zone and the subtidal zone can be performed conveniently and quickly by combining with the simple, convenient and effective zostera marina L. transplanting method provided by the invention. In addition, the materials used in the invention avoid polluting the sea areas.

Description

technical field [0001] The invention relates to seagrass field restoration and reconstruction technology, in particular to a simple method for ecological restoration of eelgrass seagrass beds. Background technique [0002] Seagrass meadows ecosystem, mangrove forest and coral reef ecosystem are considered to be three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. Seagrass is the only angiosperm that submerges in shallow water, and differentiates into organs such as roots, stems, leaves, flowers and seeds. Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass fields are high-productivity areas that can provide good habitats, nursery grounds and shelters for marine organisms such as fish, shrimp, crab, and shellfish,...
