In recent years, it has been well promoted in saline-alkali lakes in Northwest my country. Spirulina has high nutritional value and is rich in nutrients such as protein, vitamins, calcium, iron, zinc, and a special pigment protein - phycocyanin. It has a high protein content and contains a large number of elements and trace elements necessary for the human body. Spirulina has a strong photosynthetic capacity, and its photosynthetic efficiency is more than three times that of general crops. In addition, spirulina also has many health benefits such as improving immunity, lowering blood lipids, moisturizing the intestines, anti-inflammatory, and anti-oxidation, which has promoted the development of the environment and economy of saline-alkali lakes.
