Chinese cabbage, also known as Ziying, Zizai and Suocai, belongs to Cruciferae. Porphyra is distributed all over the world and grows on rocks in shallow intertidal zone. The growing period is 65438+February to May of the following year. There are many kinds of laver, and more than 70 kinds have been found. The seaweed in China is Undaria pinnatifida, a kind of seaweed that grows in the sea. Cabbage is an alga of Ulva pertusa. So China seaweed is not sea cabbage.
Seaweed application
Because of the single species of seagrass, which lives on the seabed invisible to the naked eye for a long time, the relationship between seagrass and human beings is not close in history, but with the recent 100 years, researchers have paid more and more attention to these oldest species on the earth, and seagrass has gradually entered the public's field of vision and is closely related to human life.
First of all, seaweed has been used in fishery production. Because seaweed contains a lot of edible alginic acid, starch, mannitol, potassium, sodium, chlorine, magnesium, manganese, iron, cobalt and a lot of iodine, compound fertilizer with kelp as the main component has become an irreplaceable bait for sea urchins and sea cucumbers.
Seaweed hay, especially seaweed hay belonging to Zoysia and Shrimp Algae, has the characteristics of corrosion resistance, heat preservation and durability, and is often processed into weaving, sound insulation and heat preservation materials. In northern China, coastal fishermen often use seaweed as roof building materials, which can play an excellent role in heat preservation and rain protection.
