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...
