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

Embodiment 1

[0028] A seawater microalgae regulator, comprising 20 to 30 parts of thymol, 20 to 30 parts of wintergreen leaf extract, 20 to 30 parts of perilla leaf extract and 20 to 30 parts Eucalyptus leaf extract; Holly leaf extract is wintergreen leaf oil extracted from wintergreen leaves, Perilla leaf extract is perilla leaf oil extracted from perilla leaves, Eucalyptus leaf extract is eucalyptus leaf oil extracted from eucalyptus leaves .

[0029] Thymol, refers to 5-methyl-2-isopropylphenol, molecular formula is C 10 h 14 O, it is colorless crystal or colorless crystalline powder at room temperature, with the smell of thyme or thyme. Slightly soluble in water, soluble in glacial acetic acid and paraffin oil, also soluble in ethanol, chloroform, ether and olive oil. Thymol naturally exists in the Lamiaceae plants thyme, thyme, oregano, sweet green orchid, Umbelliferae crude parsley seeds.

[0030] The formula contains Wintergreen Leaf Extract, Perilla Leaf Extract and Eucalyptus ...

Abstract

The invention discloses a seawater microalgae regulator and a microalgae algae phase regulation method using the regulator, belonging to the technical field of seawater pond cultivation. 1 to 30 parts of thymol, 20 to 30 parts of wintergreen leaf extract, 20 to 30 parts of perilla leaf extract and 20 to 30 parts of eucalyptus leaf extract; the microalgae phase regulation method includes the steps S1, adding the seawater microalgae regulator to the solvent to make a compound conditioning solution; step S2, adding clay to the compound conditioning solution, and uniformly mixing to form a mixture; step S3, adding the mixture in step S2 to seawater, and The mixture is broken up and stirred to form a suspended liquid without agglomeration; step S4, the suspended liquid formed in step 3 is evenly sprinkled in the seawater pond; the present invention can effectively reduce the structure ratio of harmful algae in the seawater pond, and adopt Plant preparation, no pollution to the environment.

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...
