In the case of growing in a plant factory as described above, the cost required for lighting for promoting photosynthesis is not foolish, and in fish farming, the removal of sediment collected at the bottom of the aquaculture pond and its disposal I was forced to have problems. The present invention is based on the combination of a plant factory and an aquaculture pond, so that unnecessary materials discharged by both of them are converted and used as necessary products, thereby reducing the production cost. Provides a new method called “Simultaneous breeding method”.

  According to the present invention, a culture pond and a plant factory are installed as described in claim 1, and the plant factory can prevent free circulation of internal and external air and promotes photosynthesis for plants by lighting for 24 hours. The oxygen generated in the plant factory is diffused into the plant factory by increasing the concentration of oxygen in the plant factory, and the concentrated factory air is led to the bottom of the aquaculture pond and air bubbles. As a result, it is possible to improve the efficiency of oxygen supply based on the dissolution of oxygen-enriched air into the culture pond water. It is related to the method for simultaneously growing plants and fish that are taken out and used as nitrogen raw materials for fertilizers used in plant factories.

  According to the present invention, the sedimentation groove for collecting the bottom sediment mainly composed of the residue of bait, feces, etc. generated in the culture pond according to claim 2 is provided at the bottom of the culture pond. The method for simultaneously growing plants and fish according to claim 1, wherein the sediment collected in said sedimentation groove is sucked out and used as a nitrogen raw material for fertilizer used in a plant factory. Let it be an aspect.

According to the present invention, as described in claim 3, the plant and the fish according to claim 1 or 2, which are formed in a state where the aquaculture pond and the plant factory are vertically stacked, are formed. The method is an embodiment.

  As described in claim 4, the present invention uses, as a plant factory, a plant factory that includes one or more shelves for plant growth and that covers the entire outer peripheral surface thereof with an airtight cover material that can be opened and closed. The method for simultaneously growing plants and fish according to any one of claims 1 to 3 is an embodiment.

  Since the present invention adopts the configuration as described in claim 1, the growth of plants and fish can be achieved reasonably while maintaining a very mutual relationship. In other words, by guiding the oxygen generated based on photosynthesis accompanying plant growth in the pond for growing fish, the high concentration oxygen air in the growth water is melted and the oxygen content in the growth water is increased. Therefore, it is possible to grow a large number of fish, improve the breeding efficiency, and at the same time secure a good aquatic atmosphere for the grown fish.

  At the same time, the bottom sediment mainly made from the residue of bait, feces, etc. generated in the aquaculture pond was taken out and used as a nitrogen raw material for fertilizer used in the plant factory. The use of fertilizer waste can be achieved, and the operation cost can be reduced. Moreover, the exothermic action that occurs during the production of fertilizer using the nitrogen raw material can be used as an element for further cost reduction by utilizing it as a heat source for heating for plant factories and aquaculture.

  The present invention has a structure as described in claim 2, that is, a cultivation of a sedimentation groove for collecting bottom sediment mainly composed of residuals such as bait and feces generated in a culture pond based on natural inflow. By collecting the sediment collected at the bottom of the pond and sucking out the sediment collected in the ditch for use as a nitrogen raw material for fertilizer used in the plant factory, the collection of the sediment is facilitated. The creation of nitrogen fertilizer is facilitated.

  The present invention is configured as described in claim 3, that is, by forming the aquaculture pond and the plant factory in a vertically stacked state, the coexistence establishment of both, ie, the establishment space Streamlining is achieved and the purpose of lowering installation costs is achieved.

  The present invention is configured as described in claim 4, that is, as a plant factory, provided with one or more stages of plant growing shelves, and the entire outer peripheral surface thereof is covered with an airtight cover material so as to be freely opened and closed. By using this, the plant factory can be simplified, and the cost of the implementation of the present invention can be reduced.

It is sectional drawing for description showing one specific Example of the method of this invention. It is an expanded sectional view for explanation showing an example of the cover object used for the method of the present invention.

  In the present invention, an aquaculture pond and a plant factory are installed. The plant factory can prevent free circulation of internal and external air, and promotes photosynthesis for plants by lighting for 24 hours. Oxygen generated based on the photosynthesis Is diffused into the plant factory, the oxygen concentration in the plant factory is enriched, the concentrated factory air is led to the bottom of the culture pond and diffused as bubbles, and the culture pond Increase the rate of oxygen supply based on the dissolution of oxygen-enriched air into the stored water, and take out the bottom sediments mainly composed of residual bait, feces, etc. generated in the aquaculture pond. This relates to a method for simultaneously growing plants and fish that is used as a nitrogen raw material for fertilizers used in Japan.

  FIG. 1 represents one embodiment of the method according to the invention. In the figure, A is a plant factory, in which one or more shelf frames are accommodated in one building, and necessary vegetables and the like are grown thereon. In the present invention, the plant factory A is indispensable to use the lighting device a for lighting for 24 hours, which promotes photosynthesis for plants and free air inside and outside. It is important to have a function that can prevent the flow of air, that is, the internal air from leaking outside. Of course, in the internal management work, the internal / external circulation is not hindered, but it is important to ensure the closeness so that the internal air does not leak to the outside at least during the cultivation.

  B is a cover material provided so as to cover the entire outer surface of the plant factory. As shown in FIG. 2, the cover material B is formed on the outer surface side of the core part 1 formed by connecting the polystyrene foam strips in a bowl shape. The waterproof sheet material 2 such as a rubber sheet is attached, and the exterior protective sheets 3 and 4 formed of a heat insulating material are attached to the entire front and back surfaces.

  When the cover material C as described above is used as a plant factory with one or more shelves for plant growth, the entire outer peripheral surface of the cover material C is covered so as to be openable and closable to ensure airtightness. belongs to. That is, when the plant factory is not a building shape but a simple shelf frame shape, it is mainly used for ensuring the above-mentioned closing property.

  C is an aquaculture pond, and the opening surface of the upper surface is covered with the plant factory A described above. And the pipe flow path 6 provided with the compressor 5 for air intake for guiding the air in the said plant factory A to the bottom part side of the culture pond C and diverging this in water is provided.

  As a result, the air is melted into the water in the pond C. At this time, the air in the plant factory A to be taken in is enriched in the oxygen concentration in the plant factory based on the release of oxygen generated in the plant factory by promoting photosynthesis to the plant by lighting for 24 hours. By introducing the converted factory air to the bottom of the aquaculture pond and diverging it as bubbles, the melting of oxygen components in the water is extremely efficient, and an oxygen concentration atmosphere in water suitable for fish farming is obtained. I can do it.

  7 is a sedimentation groove provided at the bottom of the culture pond C, and is used to collect bottom sediments mainly composed of residuals such as bait and feces generated in the culture pond based on natural inflow. . The sediment collected in the sedimentation groove 7 is sucked to the ground via a pump 8 and used as a nitrogen material for a fertilizer material used in a plant factory. It should be noted that such means for collecting sediment may be any appropriate means, for example, using a suction hose that passes through water and reaches the bottom.

  In addition, although it is the positional relationship of the plant factory A and the culture pond C, it can also be implemented by providing a plant factory in the basement-like state under the culture pond C. That is, since the light source of the plant factory is artificial, it can be implemented in such a form. Eventually, the rationalization of the space can be achieved by forming the culture pond and the plant factory in a vertically stacked state.
