Method for artificially and rapidly culturing nostoc sphaeroids kutz algae species

The invention discloses a method for artificially and rapidly culturing nostoc sphaeroids kutz algae species, and relates to the technical field of nostoc sphaeroids kutz culture. The method comprises the following steps: step 1, artificially selecting seeds; step 2, solute preparation; step 3, preparation of an algal colonization section and a nutrient solution: an operator puts the screened nostoc sphaeroids kutz seed source into a separation bin arranged above a culture dish, pure water is injected into the separation bin through a pure water tank arranged above the top of the separation bin to submerge nostoc sphaeroids kutz in the separation bin, and the nostoc sphaeroids kutz is soaked and broken; a hydraulic system is arranged at the top of the separation bin, the bottom of the separation bin is communicated with a plurality of liquid drainage holes, an operator starts the hydraulic system to pressurize the separation bin, the nostoc sphaeroides is crushed, and meanwhile, algal colonization sections an
