Embodiment 1

[0023] A sowing and planting test of subtidal eel algae was carried out by using the method of the present invention in a certain bay in Shandong.

[0024] The production of the mud box: the mud box is hollow cuboid, made of clay and fine sand, of which clay (taken from the muddy sediment in the natural sea area) accounts for 65%, fine sand (20-40 mesh; taken from the beach) Accounting for 35%, the wall thickness of the mud box is 25 mm, the inner chamber of the mud box is 200 mm long, 100 mm wide, and 25 mm high; the middle of the outer wall of the mud box is tied tightly with a 2 mm thick hemp rope. When making mud boxes and lids, mix clay and fine sand, add appropriate amount of seawater and mix well, and make mud boxes and mud box lids with the help of molds. The mud boxes and mud box lids can be used after drying.

[0025] Other materials used are as follows: ① Thin hemp rope (2 mm thick); ② The seeds of Zelpium cerevisiae were collected from July to August and stored in ...

Abstract

The invention relates to sea grass bed restoration and reconstruction technologies, in particular to a subtidal zone eel grass sowing and planting method. The method includes: using clay and fine sand to make a mud box, well mixing the seeds of eel grass with appropriate amount of fine sand and placing the mixture into the inner cavity of the mud box, sealing the opening of the mud box, throwing the mud box filled with the seeds of the eel grass into the sea of appropriate sea areas so as to perform eel grass bed ecological restoration, wherein the sowing density of the seeds of the eel grass is 1-1.5 kilograms per mu. By the eel grass sowing method simple and efficient, the problem that sea grass sowing at seabed of deep subtidal zone water areas is difficult is solved, eel grass bed restoration or reconstruction of deep subtidal zone water areas can be performed conveniently and fast, and the materials used by the method cause no sea area pollution.

Description

technical field [0001] The invention relates to seagrass field restoration and reconstruction technology, in particular to a method for sowing and planting subtidal eel algae. 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. The "seaweed" mentioned here refers to the only angiosperm submerged in shallow sea water, which differentiates into organs such as roots, stems, leaves, flowers and seeds, and "seaweed" as lower plants (such as kelp, enteromorpha, etc.) very different. [0003] 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 ...
