Subtidal zone eel grass sowing and planting method

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 ...

Problems solved by technology

At present, the sowing and planting technology of seabed algae in the deep waters of the subtidal zone is still weak, and there is a lack of simple and effective sowing and planting methods.
