Abstract

The invention discloses a preparation method of spirulina culture solution, which comprises the steps : using natural trona bittern as basic material, determining natural trona bittern of nitrogen, phosphor, potassium content, employing spectrophotometric method or colorimetric estimation, then adding into HNO#-[3]solution, HCl solution, K#-[2]SO#-[4] and H#-[3]PO#-[4]solution to make containing 0.4-0.8g / L nitrogen, 0.07-0.1g / L phosphor, 0.3-1g / L potassium, adjusting PH to 8.5-10 using acid. The invention lowers the breeding cost dramatically due to the main fertilizer natural trona bittern and keeps the original nutrients of spirulina.

Description

technical field [0001] The invention relates to a formulation of a culture solution of algae plants, and to be precise, the invention relates to a preparation method of a culture solution of spirulina. The invention belongs to the technical field of algae cultivation. Background technique [0002] Spirulina belongs to a genus of Oscillatoriaceae of Phylum Cyanophyta. Spirulina is the highest protein content found so far, which can reach 55% to 70%. The amino acid composition of protein is uniform and excellent. In addition, it also contains many A variety of vitamins, unsaturated fatty acids such as γ-linolenic acid, various trace elements and algal polysaccharides. Spirulina not only has high nutritional value, but also has excellent health care effects. Its market demand is expanding day by day, thus promoting the development of spirulina farming industry. [0003] Because spirulina has high requirements on surrounding survival and reproduction conditions, the preparati...
