To provide the construction and a method of a natural farm that gives no stress to an aquatic organism, causes no risk of disturbing an environment due to escape, is safe, and has low costs by installing an escape and hiding place of a juvenile fish, protecting the juvenile fish, improving a survival rate of the juvenile fish, culturing the juvenile fish by natural predation of an organism, employing water quality with natural purification action, and culturing the juvenile fish in the same ecosystem as that in the ambient, and to create a rich fishing place in a coast by discharging deep ocean water onto a front layer of a sea level having poor nutrition.SOLUTION: Proliferation is achieved by protecting a juvenile fish by providing: a surrounding part provided in a land side water area of an offshore breakwater block, having no bottom surface, having a lower end edge portion always contacting a water bottom, and having an upper end edge portion always being over the water level; and a hiding place for a juvenile fish that has entered the place through a clearance part, that is provided in the surrounding part, and to and from which a juvenile fish can enter and exit and an adult fish cannot enter and exit, and by fertilizing the periphery of the surrounding part by a deep water upwelling device.SELECTED DRAWING: Figure 1

The invention discloses an ocean deep water quality evaluation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring ocean deep water data through a preset ocean deep water survey station; extracting test data of the deep ocean water based on the deep ocean water data; constructing evaluation indexes of multiple evaluation aspects of the deep ocean water based on the basic characters of the deep ocean water resources; substituting the test data into the evaluation index to obtain the index score of the single index of each characteristic of the deep ocean water; and in response to the target purpose of the deep ocean water, obtaining a water quality evaluation result based on the index score of the at least one single index. According to the method, comprehensive evaluation can be carried out by selectively combining the scores of the related single indexes according to the specific target purpose of the deep ocean water, so that the evaluation result highly conforms to the actual application requirement, and the water quality evaluation of the deep ocean water can be accurately carried out.

This invention belongs to the field of cosmetic technology, specifically disclosing a deep-sea water mineral powder, its preparation method, and its application. The preparation method includes the following steps: vacuum evaporation and concentration of deep-sea water to obtain a concentrated solution; adding NaOH solution dropwise while stirring to adjust the pH, continuing stirring, centrifuging, discarding the precipitate, and obtaining the reactant; adjusting the pH to acidic, stirring at a certain speed, adding tannic acid solution dropwise, gradient heating, and allowing to stand for aging to obtain the reaction mixture; centrifuging to separate the precipitate, washing, and obtaining a wet filter cake; vacuum drying, pulverizing, and sieving to obtain the deep-sea water mineral powder. This deep-sea water mineral powder exhibits excellent water-holding capacity and oil-controlling properties, as well as excellent antioxidant activity, showing promising application prospects as a cosmetic raw material.

The invention provides a preparation method of a compound mineral concentrated solution of deep sea water, which utilizes an electrodialysis or nanofiltration technology, evaporation concentration, cooling crystallization and the like. A deep sea water concentrated solution mainly containing potassium ions, a deep sea water concentrated solution mainly containing calcium ions, a deep sea water concentrated solution mainly containing sodium ions and a deep sea water concentrated solution mainly containing magnesium ions are prepared. According to the method, a basic method for forming concentrated solutions with different mineral element proportions, baume degrees of different concentrated solutions in the preparation process, cooling temperatures of monovalent ion concentrated solutions and the like are defined, and the food nutrition enhancers with different contents of potassium, calcium, sodium and magnesium can be prepared according to requirements by utilizing the method.

The invention provides a method for producing an enhanced foliar fertilizer by using a deep sea water concentrated solution instead of a hydrosolvent, the deep sea water concentrated solution is produced more efficiently and at lower cost by adopting a magnetofluid seawater desalination separation method, and the concentrated solution produced by the method, an electrodeionization method and other methods is used as a solvent. The traditional water solvent for producing foliar fertilizers and nutrient solutions is replaced, various water-soluble enhanced foliar fertilizers and plant nutrient solutions are produced on the premise of not changing the existing equipment and process, various mineral substances and trace elements can be supplemented, the absorption rate of crops to the mineral substances and the trace elements is improved, and the water-soluble enhanced foliar fertilizers and plant nutrient solutions are obtained. The disease resistance, stress resistance, immunocompetence and growth ability of plants can be enhanced, the yield and quality of crops are improved, the usage amount of chemical fertilizers and pesticides is reduced, pollution and damage to the environment are reduced, and development of deep sea resources and green functional agriculture is greatly promoted.
