SEAWEED CULTIVATION METHOD

The present invention relates to a cultivation method of seaweed. The method is mainly to clean the seaweed with sterilized seawater, and then use the thread to connect the backbone of the seaweed and fix it in the cage, and the cage system is set in the culture tank. Then by maintaining the water in the culture tank, and then through the light-emitting unit, the water in the culture tank emits light with a light quantum flux density (PPFD) of 100, 300, 500 [mu]mol m-2s-1 from top to bottom. And the light-emitting unit continues to emit light for 10 to 14 hours a day, and inject air into the water continuously or intermittently for 13 to 24 hours a day, and the air volume of this air is 0.01~0.4 vvm. In this way, through the difference of light quantum flux density, the seaweed will eventually appear bright red, bright yellow-green, or dark yellow. And through the protection of the cage, it can effectively prevent fish or aquatic organisms from eating the seaweed, at the same time, the first thread can not on
