Description

  The present invention relates to aquatic aquaculture apparatus, aquatic aquaculture method, water for aquatic aquaculture, a hydroponic cultivation apparatus, a hydroponic cultivation method, and a hydroponic cultivation medium. More specifically, the present invention relates to an aquatic organism aquaculture device, an aquatic organism aquaculture method, and aquatic organism aquaculture water that can enhance the physiological activity function of aquatic organisms, vigorously grow and reproduce, and can be bred at high density. In addition, the present invention relates to a hydroponic cultivation apparatus, a hydroponic cultivation method, and a culture solution for hydroponic cultivation that prevent root rot and the like and are excellent in the growth of flowers and fruits.

Water quality management is necessary to breed and breed aquatic organisms such as seafood, shellfish, seaweed, seaweed, aquatic plants, and aquatic mammals in an aquarium. In particular, expensive seafood and crustaceans are sensitive to changes in the water quality environment.
Conventionally, a method for purifying water in a water tank by filtration is known as means for water quality management. An active carbon is also used for this filtering means. However, satisfactory effects are not obtained only by water purification by filtration.

As a water purification method other than filtration, for example, Patent Document 1 discloses a method of degrading ammonia excreted by fish and shellfish by passing an electric current through water.
In Patent Document 2, the water in the aquarium is pumped up, guided to the electrolysis chamber, electrolyzed in the electrolysis chamber, divided into oxygen and hydrogen, and the separated oxygen is returned to the aquarium to return the feces discharged by the organism. It is disclosed that ammonia contained in urine is oxidized to be converted into nitric acid or nitrous acid, and microorganisms are reduced by the sterilization action of oxygen, thereby deodorizing.
In Patent Document 3, oxygen and hydrogen are burned in high-pressure water in which activated carbon is dispersed, and activated carbon is burned by the combustion to obtain water in which activated carbon ultrafine particles are dispersed. It is described that it is used as an auxiliary water for purifying water for breeding. However, carbon monoxide may be generated in this combustion reaction, and carbon monoxide may be included in the purification auxiliary water, which may adversely affect living organisms.

In addition, a method for sterilization and deodorization by introducing ozone into a water tank, a device for aspirating oxygen-enriched air generated from an oxygen enricher to water in the water tank (Patent Document 4), singlet oxygen (active oxygen) ) Is brought into contact with water to activate the water (Patent Document 5).
However, even with these water purification methods using oxygen or ozone, ammonia, nitrous acid, nitrates, etc. generated from excreta of aquatic organisms cannot be decomposed and purified when they are raised at high density, so they remain in the aquarium and are The water must be changed frequently (for example, once a day). Also, high-density breeding places stress on aquatic organisms, so fighting and bullying can occur and aquatic organisms can die. As described above, in the conventional method, it is not easy and easy to maintain aquatic organisms in a healthy body, raise them at high density, and reproduce them.

Japanese Patent Laid-Open No. 4-150995 Japanese Patent Laid-Open No. 10-165955 JP 2002-66541 A JP 2004-305035 A JP-T-2002-531249

On the other hand, in the cultivation of horticultural crops and the like, it is necessary to manage the soil quality in order to grow the plant body healthily and increase the yield. However, soil management takes time and effort. In recent years, a method of cultivating a plant body using a culture solution containing nutrients and minerals necessary for the growth of the plant body without using soil (generally referred to as hydroponics and hydroponics. Hereinafter, in this specification, It is described as hydroponics).
By the way, in the hydroponics method that grows the roots in water containing nutrient solution (fertilizer), the roots of the plants may grow in the water, causing the roots to lack oxygen and weakening the plants. . Also, the water itself becomes unsanitary and may rot. Thus, oxygen (air) is diffused in water with an air pump or the like to impart movement to the water (Patent Document 6); a method of spraying the culture solution on the roots; A method of flowing down (a small amount) (Patent Document 7); a method of using a solid medium other than soil such as rock wool (rock wool), and the like are performed. However, even with these conventional methods, the propagation of aquatic fungi has become vigorous as the temperature rises, which can weaken the plant body.

JP 2007-75054 A JP 2007-89489 A

  An object of the present invention is to improve the physiological activity function of aquatic organisms, to increase the growth and reproduction ability, and to be bred at high density, and to aquatic organism aquaculture apparatus, aquatic organism cultivation method and aquatic organism cultivation water, and An object of the present invention is to provide a hydroponic cultivation apparatus, a hydroponic cultivation method, and a hydroponic cultivation culture solution that prevent root rot and the like and are excellent in the growth of flowers and fruits.

As a result of intensive studies to solve the above-described problems, the present inventors have found that radical oxygen (so-called active oxygen) is converted into aquatic organisms when only oxygen is supplied in aquatic organism cultivation or terrestrial plant hydroponics. I noticed that it adversely affects plants and plants, causes dysfunction and cell death, and accelerates aging.
Therefore, as a result of further investigation, the present inventors have diffused hydrogen-oxygen mixed gas into the aquaculture water, and cultivated aquatic organisms in the water, thereby increasing the physiological activity function of the aquatic organisms, and vigorous reproduction ability. It was also found that a healthy body can be maintained even if reared at high density.
Further, the present inventors diffused hydrogen-oxygen mixed gas into a culture solution, brought the plant root into contact with the culture solution, and hydroponically cultivated the plant body, whereby the flower color of the plant body was vivid. It was also found that it is excellent in fruit growth.
The present invention has been further studied and completed based on these findings.

That is, according to the present invention, an aquatic aquaculture apparatus comprising means for storing aquaculture water, means for producing a hydrogen-oxygen mixed gas, and means for dissolving the gas in the aquaculture water,
A method of cultivating aquatic organisms inhabiting in the aquaculture water area by disposing an aeration means in the aquaculture water area, supplying a hydrogen-oxygen mixed gas to the aeration means, diffusing the gas into the aquaculture water area, and hydrogen oxygen Aquatic aquaculture water obtained by dissolving mixed gas in aquaculture water is provided.
Further, according to the present invention, a hydroponic cultivation apparatus comprising means for storing a culture solution, means for producing a hydrogen-oxygen hybrid gas, and means for dissolving the gas in the culture solution,
Hydroponic cultivation method for growing a plant body by bringing the root of the plant body into contact with a solution obtained by dissolving a hydrogen-oxygen mixed gas in a culture solution, and hydroponic cultivation in which a hydrogen-oxygen mixed gas is dissolved in a culture solution A culture broth is provided.

(Aquatic aquaculture equipment)
The aquatic aquaculture apparatus of the present invention comprises means for storing aquaculture water, means for producing a hydrogen-oxygen mixed gas, and means for dissolving the gas in the aquaculture water. In this specification, aquaculture means artificially raising aquatic organisms. The means for storing the aquaculture water used in the apparatus of the present invention is not particularly limited, and examples thereof include a water tank, a ginger, a pipe, and a septic tank.

  Examples of the hydrogen-oxygen mixed gas used in the present invention include a gas in which hydrogen and oxygen are mixed; water described in JP 2004-204347 A, JP 3130014 A, JP 10-266900 A, and the like. And mixed gas obtained by electrolysis of.

  The gas in which hydrogen and oxygen are mixed, which is one embodiment of the hydrogen-oxygen mixed gas, may be a gas supplied and mixed from, for example, a hydrogen gas cylinder and an oxygen (or air) gas cylinder. The ratio of hydrogen and oxygen in the gas in which hydrogen and oxygen are mixed can be appropriately selected depending on the type of aquatic organisms, the shape of means for inhabiting aquatic organisms, etc., and is not particularly limited, but usually 1 mol: 99 mol-99 mol: 1 mol is preferable, 5 mol: 95 mol-95 mol: 5 mol is more preferable, 1.5 mol: 1 mol-3 mol: 1 mol is especially preferable. When a gas in which hydrogen and oxygen are mixed is used as the hydrogen-oxygen mixed gas, the hydrogen and oxygen may be mixed before being dissolved in the aquaculture water, or the hydrogen gas and oxygen may be added to the aquaculture water. Gas may be supplied separately and performed in aquaculture water.

  On the other hand, a mixed gas obtained by electrolysis of water, which is another aspect of the hydrogen-oxygen mixed gas (hereinafter, sometimes referred to as SHG (super hybrid gas) for the sake of simplicity) usually contains hydrogen and oxygen. Although it is contained in a ratio of 2 mol: 1 mol, when SHG is dissolved in the aquaculture water, the ratio of hydrogen and oxygen can be arbitrarily changed by adjusting the supply amount on the hydrogen side or oxygen side. For example, the ratio of hydrogen and oxygen in SHG can be 1 mol: 99 mol to 99 mol: 1 mol.

  Although details are unknown, it is thought that SHG contains active oxygen (or nascent oxygen) and active hydrogen (or nascent hydrogen). SHG is also considered that hydrogen and oxygen each carrying a charge are directly bonded to water molecules. Active oxygen (or nascent oxygen) and active hydrogen (or nascent hydrogen) have a negative (negative) charge and a positive (positive) charge, respectively. It is assumed that this active oxygen contributes to the oxidation of the components in the aquaculture water, and active hydrogen contributes to the reduction of the components in the aquaculture water, and the aquaculture water is purified, sterilized and activated by the balance between this oxidation and reduction. Is done. Therefore, in the present invention, it is preferable to use SHG among the hydrogen-oxygen hybrid gas.

  SHG can be obtained by the method or apparatus described in JP-A-2004-204347, JP-A-3130014, JP-A-10-266900, and the like. For example, in a substantially cylindrical electrolysis tank whose top and bottom are sealed, water in which a conductive substance such as potassium hydroxide is dissolved is placed, and a plurality of cylindrical sheets alternately arranged at regular intervals in the tank are formed. Electricity is passed through the anode and cathode to electrolyze water. There is no partition between the anode on the oxygen generation side and the cathode on the hydrogen generation side, and SHG can be obtained by immediately mixing oxygen and hydrogen generated immediately after electrolysis. In addition, SHG generators are commercially available, and examples thereof include a brown gas generator (BEST KOREA) and an E & E gas generator (Best World).

  Next, the hydrogen-oxygen mixed gas obtained by the above method is dissolved in the aquaculture water. Aquaculture water can be appropriately selected according to the type of aquatic organisms, and examples include seawater, brackish water, and fresh water. The aquaculture water may or may not contain a mineral content.

The method for dissolving the hydrogen-oxygen mixed gas is not particularly limited. For example, an air diffuser (diffuser) with a large number of fine ventilation holes is placed in an aquaculture area such as an aquarium or ginger, or in a stock tank for replacement aquaculture water. Examples include a method of supplying a hybrid gas and diffusing the culture water as fine bubbles from a vent hole; and a method of entraining the hydrogen-oxygen hybrid gas using a pump for circulating the culture water.
The air diffuser tube is not particularly limited as long as the air hole is perforated, but from the viewpoint that fine bubbles can be diffused, the cylindrical air tube formed with the air hole and the outer peripheral surface of the air vent tube And a porous body in which particles such as ceramics are integrated and formed along the surface.

The supply amount of the hydrogen-oxygen mixed gas can be appropriately selected depending on the kind of aquatic organisms, the shape of means for inhabiting aquatic organisms, and the like, and is not particularly limited, but is preferably about 0.1 per hour per 1 m ^{3 of} aquaculture water. It is 1-1000 liters, More preferably, it is 10-500 liters, Most preferably, it is 50-500 liters on average. Supply may be performed continuously or intermittently. For example, 300 liters may be supplied to 1 m ³ aquaculture water over 1 hour, then the supply of gas may be stopped for 1 hour, and 300 liters may be supplied again over 1 hour.

  The means for transporting the hydrogen-oxygen mixed gas is not particularly limited. When transported with hydrogen gas alone, hydrogen embrittlement occurs and metal parts such as pipes and connections become brittle. When transporting oxygen gas alone, the pipes and connecting parts are oxidized, resulting in reduced strength or brittleness. Further, when transporting a mixed gas of hydrogen and oxygen, the above-described action of each gas extends to the pipes and connecting parts, and normal gas pipes may not be able to withstand long-term use. In addition, a mixed gas of hydrogen and oxygen may cause an explosive reaction triggered by external electromagnetic induction or electrostatic induction depending on the mixing conditions.

  On the other hand, mixed gas (SHG) obtained by electrolysis of water is very stable, and even when transported using a normal gas pipe, hydrogen gas alone, oxygen gas alone, or a mixed gas of hydrogen and oxygen is used. Since there is no effect on the pipes and connections as occurs when transporting, normal gas pipes can be used. Also, SHG is unlikely to cause an explosive reaction triggered by external electromagnetic induction or electrostatic induction. This is because SHG is a gas having a structure in which hydrogen molecules or oxygen molecules are directly bonded to water molecules. It is considered that the water molecules in the hybrid gas (SHG) have a large latent heat of vaporization due to their large hydrogen bonds, and thus naturally suppress explosive reactions. It is also a feature of the present invention that the hydrogen-oxygen mixed gas (SHG) can be transported to the apparatus by a normal metal, plastic material pipe or the like.

  The aquatic aquaculture device of the present invention further includes instruments and devices conventionally used for breeding aquatic organisms such as filtration devices, water thermometers and water temperature controllers, pH measuring devices, lighting devices, pumps, and piping. It may be included.

  The aquatic organisms to which the aquatic organism aquaculture apparatus and culture method and aquatic aquaculture water of the present invention can be applied are not particularly limited. For example, edible fish such as tuna, salmon, cod, flounder, flounder, Thailand, skipjack, eel, puffer, trout; shellfish such as lobster, tiger prawn, king crab, king crab, snow crab; Shellfish such as clams and clams; ornamental fish such as angelfish, neon tetra, coral and goldfish; tropical fish such as discus, arowana and corydoras; aquatic mammals such as dolphins, orca, sea lions, sea lions and sea otters; And seaweeds such as seaweed, kombu, asao, hijiki, sugi nori, mozuku; seaweeds such as sea bream and sea bream.

(Hydroculture device)
The hydroponic cultivation apparatus of the present invention comprises means for storing a culture solution, means for producing a hydrogen-oxygen mixed gas, and means for dissolving the gas in the culture solution.
What is necessary is just to select the culture solution used for this invention suitably from the culture solutions used for the conventional hydroponics according to the plant to be cultivated. The culture solution contains raw water and, if necessary, organic fertilizers and inorganic fertilizers that become plant nutrients. Furthermore, a bactericide, an insecticide, a rooting agent, etc. may be contained in the culture solution as needed. The raw material water used for the culture solution is not particularly limited as long as it does not impair the growth of the plant body. In the present invention, components other than the raw material water in the culture solution may be added after dissolving the hydrogen-oxygen mixed gas.

  The means for storing the culture solution used in the present invention can be appropriately selected according to the form of hydroponics. For example, in submerged hydroponics, the cultivation bed itself is used as a means for storing the culture solution. In thin film hydroponics, a tank or the like storing a culture solution to be supplied to the inclined surface can be used.

The means for producing the hydrogen-oxygen mixed gas and the means for dissolving the hydrogen-oxygen mixed gas in the culture solution are the same as those described in the aquatic aquaculture apparatus except that the culture water is replaced with the culture solution. The supply amount of the hydrogen-oxygen mixed gas, the kind of the plant, can be appropriately selected depending on the shape or the like means to store the culture solution is not particularly limited, per culture 1 m ^3, per hour, preferably having an average 0.1 to 1000 Liters, more preferably an average of 10 to 500 liters, particularly preferably an average of 50 to 500 liters. Supply may be performed continuously or intermittently. For example, it may be supplied intermittently by repeating the supply of 15 minutes and stopping the supply for 45 minutes, or the supply method of supplying only during the daytime and stopping the supply at night. When a gas in which hydrogen and oxygen are mixed is used as the hydrogen-oxygen mixed gas, the hydrogen and oxygen may be mixed before being dissolved in the culture solution, or the hydrogen gas and oxygen may be added to the culture solution. Gas may be supplied separately and performed in a culture solution.

  In the hydroponic cultivation apparatus of the present invention, a solid medium other than soil may be provided according to the type of plant body. Examples of the solid medium include rock wool; gravel such as vermiculite, sand, and the like. Furthermore, the hydroponic cultivation apparatus of the present invention is conventionally used for hydroponic cultivation such as lighting devices, water thermometers and water temperature controllers, pH measuring devices, thermometers, hygrometers, pumps, piping, anti-frost fans, greenhouses, and filtration devices. An instrument or device used from

  The plant body to which the hydroponics apparatus and method of the present invention and the culture medium for hydroponics can be applied is not particularly limited. For example, peppers, paprika, melon, bitter gourd, watermelon, pumpkin, blueberries, strawberries, eggplant, tomatoes, grapes and other fruit vegetables; lettuce, rhubarb, mizuna, herbs, radish vegetables, wasabi vegetables, green vegetables, green pepper, Leafy vegetables such as Pakchoi, cabbage, rape, spring chrysanthemum, empty core vegetables, komatsuna, Chinese cabbage, Celtas, tarsai, honey bee, Nozawana, spinach, leek; flower vegetables such as broccoli, cauliflower, cypress; flower coconuts, beans; Cereals such as rice and wheat; root vegetables such as lotus root; bulbs such as hyacinth, crocus and tulip.

  In the hydroponic cultivation method of the present invention, the plant body is grown by bringing the root of the plant body into contact with a solution obtained by dissolving a hydrogen-oxygen hybrid gas in a culture solution. Examples of the method of bringing the liquid into contact with the root include, for example, a method in which the root is immersed in the liquid; a method in which the liquid is sprayed on the root; a method in which the root is stretched on a solid medium surface or an inclined surface; There is a method of supplying the liquid around the root using the capillary action of a solid medium such as Iwako).

  EXAMPLES The present invention will be specifically described below with reference to examples, but the present invention is not limited to the following examples.

Example 1
A diffuser tube was placed at the bottom of a water tank with a filter (1200 mm × 600 mm × 600 mm), and one end of the diffuser tube was connected to the SHG generator with a vent tube. About 0.4 m ³ of water was placed in the water tank, and the water temperature was controlled in the range of 26-30 ° C. A hydrogen-oxygen mixed gas is produced by an SHG generator comprising an electrolysis tank of water, and the gas is intermittently supplied by repeating the supply of 120 liters over 1 hour and the supply stop for 1 hour, and diffused into water. It was. Then, two 10-month-old angelfish (one male and one female) were placed in this tank and breeding was started. Frozen red caterpillar was given as food.

As a result of breeding for about 3 years, eggs were laid at a frequency of about once every two weeks, and about 50% of the eggs were hatched. Angelfish is said to generally take 10 to 12 months after birth to become an adult fish, but in this example, it was possible to breed from the first generation (first generation) parent fish to the seventh generation. That is, the average period from hatching to adult fish was 6 months on average, based on simple calculations based on the breeding period and the number of generations.
The first parent fish used in this example, which is about 4 years old, has not yet lost its fertility, and is still laying eggs.

  In general, when angelfish are raised at high density, fighting and bullying due to stress occur and most of them die. However, in this example, the aquarium became overcrowded with angel fish due to its vigorous reproductive power, but most angel fish were able to maintain a healthy body.

  According to the present invention, the stress applied to the eggs is greatly reduced, and the hatching rate is significantly higher than that of the conventional method. Furthermore, according to the present invention, eggs can be easily hatched, and anyone can easily grow fry.

Example 2
Each of the marine life shrimp and the bandits were cultured by aeration of hydrogen-oxygen mixed gas in seawater in the same manner as in Example 1. Compared to those cultivated by a method in which air was diffused, those cultivated by the method of the present invention grew well, lived well and were tight.

  The deterioration of water quality due to excrement of aquatic organisms occurs in the same way regardless of the species of aquatic organisms. The deterioration of water quality has the same adverse effect even if there is a difference in aquatic organisms. Therefore, even when the present invention is applied to aquatic organisms other than the aquatic organisms performed in Examples 1 and 2, Therefore, the quality of the aquaculture water will be improved and the same effect will be brought about.

Example 3
Three baskets are placed in a cultivation tank consisting of a plastic body container and a lid (planting stand) with three holes for placing baskets, and each hyacinth bulb is placed in the basket. Placed.
The culture solution (raw water and fertilizer) was put in the cultivation tank so that it touched the bottom of the bulb. It was left in the dark until rooting. When the roots grew, the amount of the culture solution was adjusted so that half of the roots were immersed, and the plants were cultivated using only fluorescent lights. The raw material water used for the culture solution was obtained by diffusing a hydrogen-oxygen mixed gas produced by an SHG generator into tap water through an aeration tube.
For comparison, hydroponic cultivation was performed under the same climatic environment at the same time using tap water as it was as raw material water for the culture solution and using well water as it was. In addition, the culture solution was periodically replaced at the same time.

  After about 3 months, hyacinths flowered at almost the same time by three cultivation methods. Hyacinth flowers cultivated with tap water and well water were light purple (mauve). On the other hand, the hyacinth cultivated by the method of the present invention had a deep purple flower. It has been found that the physiological function of hyacinth is activated by the method of the present invention, and the flower color becomes dark and vivid. In addition, the hyacinth cultivated by the method of the present invention has a period of time from flowering to flower wilt about twice as long as that of hyacinth cultivated with tap water or well water.

Example 4
In the same manner as in Example 3, three baskets were placed in a cultivation tank consisting of a plastic main body container and a lid (planting stand) with three holes for placing the baskets. One hyacinth bulb was placed.
The culture solution (tap water and fertilizer) was placed in the cultivation tank so that it touched the bottom of the bulb. It was left in the dark until rooting. When the roots grew, the amount of the culture solution was adjusted so that half of the roots were immersed, and the plants were cultivated using only fluorescent lights. During this time, the hydrogen-oxygen hybrid gas produced by the SHG generator was intermittently diffused through the aeration tube into the culture solution. The culture broth and root rot did not occur. Similar to Example 3, bright dark purple flowers bloomed.

  Oxygen depletion and root rot of plant bodies due to the decay of the culture solution occur in the same manner regardless of the species of the plant, but have similar adverse effects on the plant body. Therefore, even when the present invention is applied to plants other than the plants performed in Examples 3 and 4, it is considered that the water quality of the culture solution is improved as in this Example, and the same effect is brought about.

Aquatic organisms grown using the aquatic organism culture device of the present invention are less susceptible to diseases and have a strong breeding ability. According to the aquatic organism culture method of the present invention, a healthy body can be maintained even if aquatic organisms are bred at high density. When the water for aquatic organism culture of the present invention is used, the frequency of water change can be reduced, so that the stress applied to the aquatic organisms can be reduced and the hatching rate can be increased.
Plants cultivated using the hydroponics apparatus or hydroponics culture solution of the present invention do not cause root rot and the like, and are excellent in the growth of flowers and fruits. Moreover, the lifetime of a flower can be lengthened.

  The reason why such an excellent effect is exhibited by the aquatic organism cultivation method and hydroponics method of the present invention is not clear, but the following mechanism of action is presumed. Mitochondria exist in organisms that breathe oxygen. The mitochondria are intracellular organelles that convert oxygen taken by respiration into energy. Hydrogen is required to convert oxygen into energy, and it is said that electron transfer by ATP synthase is involved in the reaction between oxygen and hydrogen. When only oxygen (air) is supplied as in the prior art, electrons are directly transmitted to oxygen, and as a result, active oxygen is generated. This active oxygen is said to destroy cells and DNA. When oxygen and hydrogen are supplied as in the present invention, electron transfer to oxygen is via hydrogen, so that the reaction becomes mild. In addition, a recent study (Ohta etal. "Hydrogen acts as a therapeutic antioxidant by selectively reducing cytotoxic oxygen radicals" Nature medicine 2007.5.7 published, URL: http://www.nature.com/nm/journal/vaop/ncurrent/ abs / nm1577.html) has shown that hydrogen reduces oxygen radicals in rats and exhibits therapeutic antioxidant activity. It is presumed that such an action mechanism prevents aging (reduced vitality) of aquatic organisms and terrestrial plants, and the effects of the present invention are exhibited.
