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

Abstract

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. The structural proportion of harmful algae in the seawater pond can be effectively reduced, and no pollution is caused to the environment due to the adoption of the plant preparations.

Description

technical field [0001] The invention relates to the technical field of seawater pond cultivation, in particular to a seawater microalgae regulating agent and a microalgae microalgae regulating method using the regulating agent. Background technique [0002] Microalgae plays an important role in the seawater pond culture ecosystem. It is not only an important bait for fish, shrimp, shellfish, etc., but also an excellent indicator of the environmental conditions of the culture pond and the health of the water body. Its biomass, abundance and Population diversity can well reflect the environmental status of aquaculture ponds. For mariculture organisms, microalgae in seawater can be divided into two categories: harmful algae and beneficial algae. Among them, diatoms are the main algae of beneficial algae. Diatoms are the main bait for fish, shellfish and shrimps, especially their larvae. Together with other plants, diatoms constitute the primary productivity of the ocean. Harm...

Problems solved by technology

At present, in the face of the problem of harmful algal blooms and environmental deterioration in the breeding process, farmers still use promethazine, glyphosate and other herbicides to eliminate algae, but these chemical algae killers will not only cause environmental pollution. Pollution, and will kill beneficial algae such as diatoms in seawater ponds at the same time, and cannot effectively reduce the structural proportion of harmful algae in seawater ponds
