Seawater microalgae regulating agent and microalgae algae phase regulating method using same

The invention discloses a seawater microalgae regulating agent and a microalgae phase regulating method using the same, belongs to the technical field of seawater pond culture. According to the technical schemes of the invention, the seawater microalgae regulating agent is prepared from the following components in parts by mass: 20-30 parts of thymol, 20-30 parts of holly leaf extract,20-30 partsof perilla leaf extract, and 20-30 parts of eucalyptus leaf extract. The microalgae algae phase regulating method comprises the following steps of: S1, adding the seawater microalgae regulating agentinto a solvent to prepare a compound regulating solution; S2, adding clay into the compound regulating solution, and uniformly mixing the clay and the compound regulating solution to form a mixture; S3, adding seawater into the mixture obtained in the step S2, and dispersing and stirring the mixture to form a non-caking turbid liquid; S4, uniformly splashing the turbid liquid formed in the step 3into a seawater pond.
