Spirulina is a kind of the most ancient pronucleus photosynthetic living things. Through many years of multiple points indoor and outdoor experiments and research, it has been proved the application technology of the TA emulsion powder for the promotion of superior quality and high yield of spirulina . In the factory mode of production of spirulina, 0.01〜0.02 mg/L emulsion powder is added into the culture pool. It cannot onlg promote the cell fission of spirulina , the proliferation and growth of spirulina thread, the raise of pure rate of photosynthesis and accumulation of dry substance, but also strengthen the activity of nitric reductase and respiratory intensity of spirulina ,and remarkably increase the content of protein, amino acid, pheophytin β-carotene, chlorophyll and carotenoid. At the same time, it significantly improve the quality and the biological yield of Spirulina. The amount of yield increase can be up to 1.19〜1.76 g/d·m², the yield increase rate is 20%〜30 % . To apply TA emulsion powder as the cultivation regulator and the cultivation technology is a new creation and the prospect of the application is cheerful.
