Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kelp cultivation, in particular to a seed rope kelp cultivation raft and a cultivation method thereof. BACKGROUND

[0002] Kelp cultivation, as an important marine aquaculture industry, has been developed in China for many years. The existing kelp cultivation raft is mainly composed of buoyancy ropes, cultivation seed ropes and positioning ropes. The working principle is to provide buoyancy by the floating ball on the buoyancy rope, so that the whole cultivation raft can float on the sea surface, and the cultivation seed rope is used to fix the kelp seed, and the positioning rope is used to keep the stability of the whole cultivation raft. However, the existing kelp cultivation raft has some problems in actual use.

[0003] At present, the Chinese patent publication shows that the traditional kelp cultivation raft mainly relies on the fixed floating ball, which is difficult to flexibly adjust the buoyancy according to the growth needs of kelp. For example, the document with the application number CN108012917A proposes a long seed rope kelp cultivation raft, which solves the problem of inconsistent water layer of kelp cultivation by setting foam small floaters on the seed rope, but the buoyancy of the floating ball still cannot be automatically adjusted according to the real-time needs of kelp growth. At the same time, the document with the application number CN102085306B also provides a kelp cultivation raft, but it does not involve the automatic design of buoyancy adjustment. This shows that the existing technology has deficiencies in buoyancy adjustment. On the one hand, the traditional floating ball is mostly made of plastic, which is easy to age and break down due to natural factors such as wind and wave impact, ultraviolet radiation, etc., and the buoyancy decreases. On the other hand, the existing technology lacks the function of automatically adjusting the buoyancy, and usually needs manual adjustment of the buoyancy device, which cannot respond to the changes of kelp growth needs in time. In addition, the existing floating ball does not have the slow-release function, and cannot slowly release carbon dioxide and other gases to adjust the buoyancy and water environment. SUMMARY
