Problems solved by technology

[0005] However, due to environmental pollution and other issues, seaweed resources are gradually degrading now, and the construction of artificial algae farms is mostly concentrated in the intertidal zone, or areas with a water depth of 3-5m, because the growth of artificially propagated seaweed seedlings requires photosynthesis, so the seawater is too deep Areas where seedlings cannot grow, thus restricting the construction of seaweed farms in deep water areas

Embodiment 1

[0075] A method for constructing a seaweed field, comprising the following steps:

[0076] (1) Algae reef seaweed nursery:

[0077] 19×19cm made of cement, sand, etc., with a thickness of 2cm, and the cement board is used as the algae reef. The algae reefs are soaked in fresh water for 15 days, exposed to sunlight for 5 days, soaked in sea water for 3 days, and rinsed with sea water for 3 to 5 times to remove surface dirt. Vegetable Asparagus collects the tops of vegetative branches with strong growth and dark red algae, and leaves 30-60cm as seedlings. Asparagus collects vegetative shoots as seedlings. 3 days before leaving the pond, strengthen the washing intensity and frequency of the seedling pond to increase the attachment strength of seaweed seedlings; the algae reef nursery pond is drained, and the water surface is 3-5cm higher than the algae reef. Moderately cover with net curtains or blackout curtains, and sprinkle seawater every 20 minutes to keep the algae reefs ...

Embodiment 2

[0082] A method for constructing a seaweed field, comprising the following steps:

[0083] (1) Algae reef seaweed nursery: 19cm×19cm made of cement, sand, etc., with a thickness of 2cm, and the cement board is used as the algae reef. The algae reefs are soaked in fresh water for 15 days, exposed to sunlight for 5 days, soaked in sea water for 3 days, and rinsed with sea water for 3 to 5 times to remove surface dirt. Kelp selects the algae with the sporangia in sheets as the algae. Dry the kelp outdoors in the shade for 2-3 hours to promote ripening. The number of kelp planted vegetables is 1 plant / m2, and the density of kelp attached seedlings under the microscope (10×10 times) is ≥7 gametes, and the attachment time is 12-24h, then the vegetables can be fished out and temporarily raised for 3-5 days. 3 days before leaving the pond, strengthen the washing intensity and frequency of the seedling pond to increase the attachment strength of seaweed seedlings; the algae reef nurs...

Abstract

The invention discloses a method for constructing a seafloor seaweed field. The method comprises the following steps that a plurality of small sample frames are arranged in an algal reef fixing frame, and a plate-shaped algal reef attached with seaweed seedlings is arranged in each small sample frame; then a bottomless seaweed root protection cover covers each small sample frame; and finally, the bottom surface of the algae reef fixing frame is fixed to any surface of a cubic reef through a connecting piece after the algae root protection cover is mounted. When the length of the algae is larger than 5 m, the cubic reef is rotated by 90 degrees, the algae reef fixing frame is arranged from the front face to the side face, the algae are long, the upper half part of the algae can perform photosynthesis, the growth requirement of the algae is met, and therefore the problem that proliferated algae reef seedlings die due to the fact that the water depth is larger than 10 m, and illumination intensity is insufficient is solved. A three-side three-dimensional algae field is finally formed in the same mode, algae groups are formed at different time, and algae have better harmful condition resistance; and the single-sided algae can be split from the three-dimensional algae field to other seawater areas larger than 10 m but smaller than 15 m, and the method can be used for constructing an ecological field with a short construction period.

Description

technical field [0001] The invention relates to a construction method of a seaweed field, which belongs to the technical field of marine ecology. Background technique [0002] Seaweed farm is a near-shore marine ecosystem composed of large brown algae and other marine biological communities that grow on the hard bottom of the continental shelf in the cold temperate zone. A natural algae field is a luxuriant seagrass or seaweed community within a water depth of about 20m. The artificial seaweed farm is a dense seaweed community formed by artificially placing attachment bases to attach seaweed spores to form seedlings in suitable areas in shallow seas or inner bays, or artificially transplanting wild seaweed seedlings to promote the proliferation and growth of various large seaweeds. [0003] As an important ecological type, seaweed farm is an ecosystem with unique functions. It has a prominent position in the development of coastal marine biological resources and environment...
