紫菜(Porphyra)是人们喜爱的一种富有营养的食品,其中蛋白质和氨基酸的含量在海藻中是比较高的,它们在紫菜的生理代谢过程中起着相当重要的作用。如在紫菜中约占2％的色素蛋白大部分由氨基酸构成。 近年来,在我国北方和南方都进行着紫菜的大规模全人工采苗和养殖,同时对其进行了广泛的生态学研究。从生产实践的经验得知,紫菜的质量随养殖地区、季节、水质肥 Porphyra is a kind of nutritious food that people like. The content of protein and amino acid in seaweed is relatively high. They play a very important role in the physiological metabolism of seaweed. For example, about 2% of the pigment protein in seaweed is composed of amino acids. In recent years, large-scale full-scale seedling and breeding of seaweed have been carried out in the northern and southern parts of China. At the same time, extensive ecological research has been conducted on the laver. From the experience of production practice that the quality of seaweed breeding area, season, water quality and fertilizer
