Description

  The present invention relates to a facility for mutual cultivation of spinach and mushrooms in which a hydroponic cultivation room for spinach and a cultivation room for mushrooms are in communication.

  Mushrooms are fungi and want high temperature and humidity without light. Moisture absorbs from humidity and grows. Although the conditions differ depending on the mushroom, for example, in the case of a bamboo shoot, the growth is activated when the humidity is around 90% and the temperature is 22 degrees or more. In particular, it is preferable that the oxygen concentration is high (because oxygen respiration is not carried out) and the carbon dioxide concentration is low. Mushrooms are parasitic fungi that grow by absorbing nutrients from parasites without photosynthesis. If there is a nutrient source and high humidity and high temperature, fungi are basically activated.

  On the other hand, since there are many kinds of plants, the cultivation conditions differ depending on the kind, but basically, the cultivation conditions differ between the seed germination time and the germination time for most kinds. At the time of germination, the cultivation conditions are the same as the growth of the mushrooms, but after the cultivation, the cultivation conditions are different between the root part and the leaf part. The leaf part is important for environmental factors such as light quantity and carbon dioxide concentration for photosynthesis, and low humidity, wind, and low pressure, but the root part is nutrient source, water (or high humidity), to absorb nutrients, Pressure is important.

High humidity, oxygen, and high temperature are preferable for mushrooms to promote growth, and many plants (in this case, vegetables) are accelerated under reverse conditions to mushrooms. Especially for winter vegetables, low humidity, carbon dioxide, and low temperature are the cultivation conditions for promoting growth, and the cultivation conditions for promoting growth are completely opposite to mushrooms.
Spinach is difficult to grow as a winter vegetable, and the yield becomes unstable unless the above-described cultivation conditions for promoting growth such as low humidity, carbon dioxide, and low temperature are stably provided.
Conventionally, in order to cultivate mushrooms and vegetables individually, there is a problem that the capital investment for creating the growth environment and running costs such as electricity are increasing.

  Efficient use of cultivation conditions for promoting growth that are completely different between mushrooms and vegetables (characteristics where unnecessary conditions are advantageous to the other party) If the cultivation environment can be circulated mutually, a closed and circulated cultivation environment can be constructed, and significant savings in electricity and water costs can be expected.

  However, conventionally, carbon dioxide exhausted by respiration of fungi cultivated in the first space is consumed for photosynthesis of plants or algae that perform photosynthesis cultivated in the second space connected to the first space. As a closed-loop chain cultivation method for carbon dioxide to be applied to the amount of carbon dioxide, a method of adjusting the amount of carbon dioxide discharged by fungal respiration and the amount of carbon dioxide consumed for photosynthesis of plants or algae under predetermined conditions However, for example, it is disclosed in the following Patent Document 1.

  In Patent Document 1, a large amount of carbon dioxide is required for an artificial cultivation system for plants that performs photosynthesis, which is performed as a proposition for air pollution due to the emission of carbon dioxide (carbon dioxide) to the atmosphere, global warming, and food security. Plants or algae that photosynthesis the carbon dioxide gas discharged by the respiration of fungi, focusing on the problem that it costs cultivation costs to purchase carbon dioxide gas and that separate energy is consumed for carbon dioxide production etc. The idea to be used for artificial cultivation is described.

JP 2012-7

By the way, as mentioned above, mushrooms prefer high humidity, oxygen, and high temperature, while spinach prefers low humidity, carbon dioxide, and low temperature, both of which are under reverse cultivation conditions for promoting growth. It is necessary to set different temperature and humidity conditions for the mushroom cultivation facility and the spinach cultivation facility, respectively.

However, in the cultivation method described in Patent Literature 1, the temperature and humidity in each of the first space for cultivating fungi, the second space for cultivating plants or algae for photosynthesis are suitable for the growth of the cultivation target. Using separate gas temperature control devices and humidifiers (or dehumidifiers) to adjust the temperature and humidity to a certain level will result in energy loss, and the running cost of using electricity and water will be reduced accordingly. It will increase.

Prior to the description of the embodiments, the operational effects of the present invention will be described.
The mutual cultivation equipment for spinach and mushrooms of the present invention includes a spinach hydroponic cultivation room covered with a thermal barrier, a mushroom cultivation room covered with a thermal barrier, a spinach hydroponic cultivation room, and a mushroom cultivation room. Is supplied between the two and the air that is rich in oxygen generated in the spinach hydroponic cultivation room, and the air that is rich in carbon dioxide generated in the mushroom cultivation room is supplied with spinach hydroponics A predetermined temperature difference is provided so that the temperature in the spinach hydroponic cultivation room is higher than the temperature in the spinach hydroponic cultivation room and the air exchange / decompression means for supplying pressure to the room and depressurizing the spinach hydroponic cultivation room The first gas temperature adjusting device, the second gas temperature adjusting device for lowering the temperature of the spinach hydroponics chamber provided in the spinach hydroponics chamber, and the mushroom cultivation chamber Furthermore, the temperature t1 in the spinach hydroponics chamber is lower than the desired temperature by driving only the third gas temperature adjustment device for raising the temperature in the mushroom cultivation chamber and the first gas temperature adjustment device, and the mushroom When the temperature t2 in the orchid cultivation room is equal to or higher than a desired temperature, only the first gas temperature adjusting device is driven, and the second gas temperature adjusting device and the third gas temperature adjusting device are stopped.

And the first gas temperature adjusting device, the second gas temperature adjusting device, and the third gas in any one of the third drive control patterns for stopping the second gas temperature adjusting device. Spinach hydroponics that occurs when adjusting the temperature difference between the mushroom cultivation room and the spinach hydroponics room by controlling each drive of the temperature regulation device and at least the first gas temperature regulation device. A dehumidifying water supply device that supplies dehumidified water in the cultivation room to the mushroom cultivation room, and a humidifying device that humidifies the mushroom cultivation room using the dehumidified water supplied to the mushroom cultivation room by the dehumidification water supply device. And.

  A first gas temperature control device that provides a predetermined temperature difference so that the temperature in the mushroom cultivation room is higher than the temperature in the spinach hydroponics room, as in the mutual cultivation facility for spinach and mushrooms of the present invention. The second gas temperature control device for lowering the temperature in the spinach hydroponics room provided in the spinach hydroponic cultivation room, and the temperature in the mushroom cultivation room provided in the mushroom cultivation room By driving only the third gas temperature adjusting device and the first gas temperature adjusting device, the temperature t1 in the spinach hydroponic cultivation room is lower than the desired temperature, and the temperature t2 in the mushroom cultivation room is higher than the desired temperature. A first drive control pattern for driving only the first gas temperature adjusting device and stopping the second gas temperature adjusting device and the third gas temperature adjusting device. When the temperature t1 in the spinach hydroponics chamber exceeds the desired temperature by driving only the device, the temperature t1 in the spinach hydroponics chamber is driven by driving the first gas temperature adjusting device and the second gas temperature adjusting device. The temperature t2 in the mushroom cultivation room is desired by driving only the first gas temperature adjusting device, the second drive control pattern for stopping the third gas temperature adjusting device, When the temperature falls below the temperature, the first gas temperature adjusting device and the third gas temperature adjusting device are driven so that the temperature t2 in the mushroom cultivation room is equal to or higher than the desired temperature, and the second gas temperature The drive of each of the first gas temperature adjustment device, the second gas temperature adjustment device, and the third gas temperature adjustment device is controlled by any one of the third drive control patterns for stopping the adjustment device. If Sonaere control device, the following effects can be obtained.

  For example, when the temperature difference between the outside air and the cultivation room in spring or autumn is relatively small, the temperature of the spinach hydroponic cultivation room and the mushroom cultivation room is driven only by the first gas temperature adjustment device via the control device. The difference can be set to a predetermined temperature difference or more, and the temperature in the spinach hydroponic cultivation room and the temperature in the mushroom cultivation room can be adjusted to the desired growth conditions. In addition, for example, since the temperature of the outside air becomes high as in summer, the temperature difference between the spinach hydroponic cultivation room and the mushroom cultivation room can be determined only by driving only the first gas temperature adjusting device via the control device. If the temperature in the spinach hydroponics room becomes higher than the temperature suitable for the desired growth conditions even when the temperature difference is equal to or greater than the predetermined temperature difference, the second gas temperature control device is driven to run the spinach hydroponics room. By cooling, the temperature in the spinach hydroponics room can be adapted to the desired growth conditions. Further, for example, since the temperature of the outside air becomes low as in winter, the temperature difference between the spinach hydroponic cultivation room and the mushroom cultivation room can be determined only by driving only the first gas temperature adjustment device via the control device. If the temperature in the mushroom cultivation room becomes lower than the temperature suitable for the desired growth conditions even if the temperature difference is greater than or equal to the predetermined temperature difference, the third gas temperature control device is driven to cool the mushroom cultivation room. Thus, the temperature in the mushroom cultivation room can be adapted to the desired growth conditions. As described above, when the temperature of the outside air is relatively gentle, the driving of the gas temperature adjusting device is adapted to the growing conditions in the spinach hydroponics chamber and the mushroom cultivation chamber by driving only one gas temperature adjusting device. Since it is only necessary to drive two gas temperature control devices when the temperature of the outside air is biased to either high or low, the two cultivation rooms with different conventional growth conditions In order to obtain a desired temperature for each, the amount of electricity used can be reduced as compared with a configuration in which separate gas temperature adjusting devices are always driven.

Further, when the spinach hydroponics chamber is cooled via the indoor unit of the first gas temperature adjusting device and the indoor unit of the second gas temperature adjusting device, dehumidified water is generated.
However, it occurs when adjusting the temperature difference between the mushroom cultivation room and the spinach hydroponic cultivation room by driving at least the first gas temperature adjusting device as in the mutual cultivation facility for spinach and mushrooms of the present invention. A dehumidifying water supply device that supplies dehumidified water in the spinach hydroponic cultivation room to the mushroom cultivation room, and a humidifying device that humidifies the mushroom cultivation room using the dehumidified water supplied to the mushroom cultivation room by the dehumidifying water supply device. Can effectively utilize the water generated in the spinach hydroponic cultivation room as part of the moisture necessary to increase the humidity of the mushroom cultivation room, and increase the humidity of the mushroom cultivation room accordingly. Therefore, the amount of water used from the external water supply can be reduced.

In the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, the dehumidified water supply device is further generated when the temperature of the spinach hydroponics chamber is lowered by driving the second gas temperature control device. The dehumidified water that is generated when the temperature of the spinach hydroponics room is lowered by driving the second gas temperature control device is configured to supply the dehumidifying water to the mushrooms cultivation room. A second dehumidified water supply device that supplies the water to the mushroom cultivation room using the dehumidified water supplied to the mushroom cultivation room by the second dehumidified water supply device. To do.
If it does in this way, the water generated when lowering the temperature in the spinach hydroponics chamber by driving the second gas temperature control device will also be a part of the moisture necessary for humidifying the mushroom cultivation chamber As a result, the amount of water used from the external water supply can be further reduced in order to increase the humidity of the mushroom cultivation room.

In addition, in vegetables, leaf growth and root growth interact (positive correlation), and in order for a leaf to grow, the root needs to grow, and for the root to grow, the leaf grows. Must. Photosynthesis is necessary for the growth of leaves, but light alone is insufficient for photosynthesis, and nutrients necessary for synthesis must be given to the leaves from the roots. However, plants do not have a part corresponding to the heart of a living organism, and basically use the force of an osmotic pressure difference utilizing ions or the like to suck up moisture against gravity. Nutrients are dissolved in the water, and the water is evaporated in the leaves and used for photosynthesis.
However, in the case of tomatoes etc., by avoiding water to the roots, sugar is produced in the living body and sweet berries are produced in an attempt to increase the osmotic pressure. There is a disadvantage that it takes. On the other hand, since many leafy vegetables do not need to be sweet, basically it is desirable to give the roots moisture and grow efficiently, and spinach also needs to enlarge its leaves in that way. is there.

  When growing spinach, the problem is that its growth is slow (basically the area of leaves that can be photosynthetic is small), the temperature rises, and the sunshine time exceeds 12 hours. ) Standing and trying to bloom. In such a state, the growth of the leaf stops and becomes hard and the commercial value decreases. For this reason, it is necessary not to hit the bag. For this purpose, it is necessary to set the light irradiation time to 12 hours or less without increasing the temperature. However, if the light irradiation time is set to 12 hours or less, the photosynthesis is insufficient and leaves are difficult to grow. Therefore, in the cultivation of spinach, it is important to increase the osmotic pressure difference, and for that purpose, it is important to activate the evaporation of moisture from the leaves.

  However, like the spinach and mushroom mutual cultivation equipment of the present invention, it is provided between the spinach hydroponic cultivation room and the mushroom cultivation room, and contains air containing a lot of oxygen generated in the spinach hydroponic cultivation room. Air supply / decompression means is provided for supplying the mushroom cultivation room with air containing a large amount of carbon dioxide generated in the mushroom cultivation room to the spinach hydroponic cultivation room, and depressurizing the spinach hydroponic cultivation room. As a result, the oxygen generated in the spinach hydroponic cultivation room can be easily exchanged with the carbon dioxide generated in the mushroom cultivation room, and the pressure in the spinach hydroponic cultivation room decreases, so that the leaves in the spinach hydroponic cultivation room It becomes easy to evaporate the water from the water and facilitates the growth of spinach.

  In the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, the air exchange / depressurization means is connected to the upper position in the spinach hydroponic cultivation room and communicates with the mushroom cultivation room. An oxygen supply pipe for sending air containing a large amount of oxygen generated in the room to the mushroom cultivation room and a lower position in the mushroom cultivation room, having an inner diameter of about one quarter of the inner diameter of the oxygen supply pipe A carbon dioxide supply pipe for sending air containing a large amount of carbon dioxide generated in the mushroom cultivation room to the spinach hydroponics room, and an oxygen supply pipe in the spinach hydroponics room It is provided with a ventilation fan that is provided in the vicinity of the connecting portion and feeds air from the spinach hydroponic cultivation room to the mushroom cultivation room.

This makes it easy to exchange the oxygen-rich air generated in the spinach hydroponics room and the air rich in carbon dioxide generated in the mushrooms culture room, and the spinach hydroponic room is depressurized. Thus, the water content of spinach leaves can be easily evaporated, and the effect of promoting the growth of spinach in the hydroponic cultivation room can be realized.
Specifically, since oxygen generated from spinach in the spinach hydroponics room is lighter than carbon dioxide, it moves upward in the spinach hydroponic room. The oxygen-covered air that has moved upward in the spinach hydroponic cultivation room is sucked out through the ventilation fan and supplied to the mushroom cultivation room through the oxygen supply pipe. Moreover, since carbon dioxide generated from mushrooms in the mushroom cultivation room is heavier than oxygen, it moves downward in the mushroom cultivation room. At this time, the inner diameter of the carbon dioxide supply pipe is only about ¼ of the inner diameter of the oxygen supply pipe, and as described above, the oxygen-covered air generated in the spinach hydroponics chamber is sucked out through the ventilation fan. Therefore, the spinach hydroponics chamber is in a reduced pressure state. Moreover, as a result of the spinach hydroponic cultivation room being in a reduced pressure state, carbon dioxide is supplied to the spinach hydroponic cultivation room via the carbon dioxide supply pipe.

  In the mutual cultivation facility for spinach and mushrooms according to the present invention, preferably, the first gas temperature adjusting device includes an outdoor unit provided in the vicinity of the connection portion with the oxygen supply pipe in the mushroom cultivation room, and spinach. It consists of an indoor unit provided in the vicinity of the connection with the carbon dioxide supply pipe in the hydroponic cultivation room.

  In this way, if the first gas temperature adjusting device is composed of an outdoor unit provided in the mushroom cultivation room and an indoor unit provided in the spinach hydroponics room, only one gas temperature adjusting device is provided. It is possible to implement a temperature difference between the two rooms so that the temperature of the spinach hydroponic cultivation room and the mushroom cultivation room is adjusted to the growth conditions. Moreover, while providing the outdoor unit in the 1st gas temperature control apparatus near the connection part with the oxygen supply pipe in a mushroom cultivation room, the carbon dioxide supply in the spinach hydroponic cultivation room is the indoor unit in the 1st gas temperature control apparatus. If it is provided in the vicinity of the connecting portion with the pipe, it becomes easy to make the temperatures in the mushroom cultivation room and the spinach hydroponics room most uniform.

In the mutual cultivation facility for spinach and mushrooms according to the present invention, the predetermined temperature difference between the mushroom cultivation room and the spinach hydroponics room is preferably 6 degrees or more.
The temperature suitable for growing spinach is relatively low, and the temperature suitable for growing mushrooms is relatively high. If the predetermined temperature difference between the mushroom cultivation room and the spinach hydroponics room is 6 degrees or more, each cultivation room is easily brought to a temperature that satisfies the cultivation conditions for promoting growth.

Moreover, in the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, an evaporation promoting device that promotes evaporation of moisture in the leaves by sending a breeze to the spinach leaves during cultivation in the spinach hydroponics chamber. I have.
In this way, the amount of water evaporation from the spinach leaves increases, and the osmotic pressure difference between the spinach root part and the leaf part can be increased, and it is easy to suck water into the leaf part through the roots. As a result, many nutrients necessary for photosynthesis contained in moisture can be supplied to the leaves. Therefore, leaf growth is promoted.

Further, in the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, the spinach hydroponics room has a spinach above the nutrient solution supplied to the hydroponics tray and hydroponics tray that form the nutrient solution tank. Has a hydroponics panel for mounting or holding the hydroponic culture panel, and the hydroponics panel includes an evaporation preventing member that prevents evaporation of water supplied from below.
If the water content of the spinach root is insufficient, it will be difficult to supply water from the root to the leaves.
However, if the hydroponics panel is provided with an evaporation preventing member that prevents evaporation of moisture supplied from the lower portion as in the present invention, the moisture from the nutrient solution tank can be sufficiently supplied from the roots to the leaves. .

In the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, the hydroponics panel is provided with a sponge for holding the spinach provided with a notch for guiding the roots of the growing spinach. The evaporation preventing member is made of a resin film that covers the upper surface of the sponge.
If it does in this way, it can be realized that the moisture from the nutrient solution tank by the evaporation preventing member is sufficiently supplied from the roots to the leaves.

In the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, a hydroponic cultivation tray has a mesh-like fiber member that supports spinach roots extending from a sponge into a lower nutrient solution.
The roots of spinach during hydroponics grow downward and extend from the sponge provided in the hydroponics panel into the nutrient solution below.
However, if the extended roots are likely to swing in the nutrient solution due to the flow of the nutrient solution, the roots are finely spread in the lateral direction and the leaves are likely to spread in the lateral direction accordingly.
However, as in the present invention, if there is a mesh-like fiber member that supports the roots of spinach extending into the nutrient solution, the nutrient solution is applied to the roots while maintaining the root in a stable state in the nutrient solution. Because it can supply enough, the roots will grow straight and the leaves will grow straight.

In the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, an oxygen supply device for supplying oxygen to the roots of spinach is provided in the nutrient solution tank.
In this way, oxygen necessary for root growth can be reliably supplied, and leaf growth is promoted accordingly.

In the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, the spinach hydroponic cultivation room has an LED lighting device for illuminating the spinach being cultivated.
In the mutual cultivation facility for spinach and mushrooms of the present invention, preferably, the spinach hydroponic cultivation room illuminates the hydroponic cultivation tray, the hydroponic cultivation panel, and the spinach in the hydroponic cultivation panel. The artificial light type cultivation equipment having the LED lighting apparatus is provided in a state where a plurality of stages are stacked in the vertical direction.

At present, almost all spinach hydroponics in Japan is in a solar power plant. Since the solar power plant is large, it is cultivated in a place away from the city center, which is a mass consumption area. However, spinach grows quickly after harvesting, so it is desirable to cultivate in the suburbs, especially when considering harvesting in the summer.
In addition, as described above, spinach needs to have a small leaf surface so that the sunshine time does not exceed 12 hours in order to give value as a product, and the leaf area per strain is small. The yield is very bad compared to other vegetables. However, in a solar power plant, it is difficult to cultivate by controlling the light irradiation time of spinach in the summertime with long sunshine hours, and the harvest tends to be unstable.

However, like the spinach and mushroom mutual cultivation equipment of the present invention, in the spinach hydroponic cultivation room, if the LED lighting apparatus is used for lighting spinach, the time to irradiate spinach can be controlled, even in summer It can be harvested stably. In addition, spinach cultivation with artificial light by LED illumination can grow spinach at a rate several times faster than spinach cultivation with sunlight.
In addition, like the spinach and mushroom mutual cultivation facility of the present invention, the spinach hydroponic cultivation room has a hydroponic tray, a hydroponic cultivation panel, and an LED lighting device that illuminates the spinach in the hydroponic cultivation panel. If the artificial light-type cultivation equipment is stacked in a vertical direction, the cultivation amount of spinach per installation area of the cultivation equipment in the spinach hydroponics room can be increased several times. It becomes possible to increase the yield of spinach even in a small space nearby.
In addition, in a spinach hydroponic cultivation room, when an LED lighting fixture is used for illumination of spinach during cultivation, the light source of the LED lighting fixture and the spinach approach each other. And the heat | fever of the light source of LED lighting fixture acts so that the temperature of the cultivation space of a spinach may be raised. However, in the mutual cultivation equipment for spinach and mushrooms of the present invention, the control device for controlling the driving of the first gas temperature adjusting device, the second gas temperature adjusting device, and the third gas temperature adjusting device, In order to control the temperature t1 in the spinach hydroponics chamber to be equal to or lower than the desired temperature by driving the gas temperature control device 1 or the second gas temperature control device, the spinach is cultivated by the heat of the light source of the LED lighting apparatus. Will not be adversely affected.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Exchange of oxygen and carbon dioxide and adjustment of pressure Spinach leaves cultivated in the spinach hydroponics section 11 in the spinach hydroponics chamber 10 absorb carbon dioxide and discharge oxygen during photosynthesis. For this reason, the air in the spinach hydroponics chamber 10 contains a lot of oxygen. Since oxygen is lighter than carbon dioxide, it moves to the upper part of the spinach hydroponics chamber 10.
On the other hand, mushrooms cultivated in the mushroom cultivation unit 21 in the mushroom cultivation room 20 absorb oxygen and discharge carbon dioxide during growth. For this reason, the air in the mushroom cultivation room 20 contains a lot of carbon dioxide. Since carbon dioxide is heavier than oxygen, it moves to the lower part of the mushroom cultivation room 20.
Air containing a large amount of oxygen moved to the upper part of the spinach hydroponic cultivation room 10 is sucked out from the spinach hydroponic cultivation room 10 by the ventilation fan 33, passes through the oxygen supply pipe 31, and is sent into the mushroom cultivation room 20.
