China originally did not produce kelp, 1927 and 1930 by the introduction of Japan, the first in Dalian culture, and then the mass kelp aquaculture industry flourished. Due to the natural light low-temperature nursery and kelp all artificial raft culture technology of the thick foundation.

In the 1950s, the "Autumn Seedling Method" was improved to Summer Seedling Method, which greatly increased the yield. 60-70s, new varieties of kelp were obtained by genetic breeding, and then with the deepening of the research technology of kelp gametophyte cloning and breeding, the kelp seed preservation, the cultivation of new varieties, and the seedling production have made great progress, which has greatly promoted the development of kelp aquaculture industry. The development of kelp aquaculture industry has played a great role in promoting the development of kelp.
