Description

Technical Field

[0001] The utility model relates to the technical field, and in particular to a device for cultivating kelp seedlings at sea. Background Art

[0002] Kelp (Laminaria japonica) is a perennial large edible algae. The spore body is large, brown, flat and ribbon-shaped. It is divided into blades, petioles and holdfasts, and the holdfasts are rhizoid-shaped. The blades are composed of epidermis, cortex and medullary tissues, and there are spore sacs at the bottom of the blades. It has a mucus cavity that can secrete slippery substances. The holdfasts are tree-like branches used to attach to the rocks on the seabed, and grow in the sea with lower water temperatures. Kelp is low-cost and nutritious, and is an important marine resource.

[0003] Kelp is a subarctic algae, a species endemic to the North Pacific Ocean, with some kelp distributed in the Atlantic Ocean. Most kelp is distributed in the Northern Hemisphere, while a small amount is also distributed in the Southern Hemisphere. It generally grows on the rocks on the seabed in the subtidal zone. The growth of kelp is mainly affected by factors such as temperature, light, nutrients and plant hormones.

[0004] my country has been cultivating kelp since the 1950s. Since the artificial raft culture of kelp was started, autumn seedlings, summer seedlings, early autumn seedlings, summer seedlings, spring seedlings and two-year seedlings have been tested and produced, and the seedling production has been deeply explored. It is mainly divided into conventional seedling raising technology and kelp gamete seedling technology.
