Composite medium for cultivating Spirulina platensis

The invention belongs to the technical field of alga cultivation, and discloses a composite medium for cultivating Spirulina platensis. The composite medium comprises sodium nitrate, sodium bicarbonate, sodium chloride, ammonium ferric citrate, sodium molybdate, zinc sulfate, propionamide, wheat bran extract and rice straw extract. The medium uses a large amount of agricultural wastes, and the quantity of raw material components is small, so the cost is saved. 本发明属于藻类培养技术领域，公开了种用于培养钝顶螺旋藻的复合培养基，其包括如下原料，硝酸钠，碳酸氢钠，氯化钠，柠檬酸铁铵，钼酸钠，硫酸锌，丙酰胺，麦麸提取液，水稻秸秆提取液。本发明培养基使用了大量农业废弃物，原料组分相对较少，节约了成本。
