Embodiment 1

[0024] In a bay in Shandong, the method of the present invention was used to carry out the transplantation of large leaf algae and the restoration and reconstruction of seagrass beds. The materials used are as follows: ① Thin cotton rope (2 mm thick, placed in sea water, degraded at 20 ℃ for three months); ② Elliptical to long stones collected by the sea (weight range 80- 120g), the surface of the stone is relatively rough; ③The fresh leaf algae plants are collected in natural sea areas, and the crown of the leaf algae is cut off to make the height of the leaf algae 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 a seagrass field restoration and reconstruction technology, in particular to a simple and convenient method for ecological restoration of a large leaf alga seagrass bed. Background technique [0002] The Seagrass meadows ecosystem, along with mangroves and coral reef ecosystems, are considered to be the three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass is significantly higher than that of mangroves and coral reefs. Seagrass is the only angiosperm submerged in shallow water, and it differentiates into organs such as roots, stems, leaves, flowers and seeds. Like forests on land, lush seagrass fields are an important symbol of a healthy marine environment and are precious "submarine grasslands" or "submarine forests." The seagrass field is a high-productivity area, which can provide a good habitat, nursery and refuge for fish, shrimp, crabs and shellfish an...
