Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant cultivation apparatus for growing plants by using a three-wavelength region fluorescent lamp and a far-infrared LED as artificial light sources, and a cultivation method using the same.

[0002]

2. Description of the Related Art In recent years, a method has been studied and developed which incorporates appropriate environmental conditions necessary for growing plants into facilities and efficiently mass-produces the plants without being affected by natural weather. Control items may component, the liquid temperature and the like of the light-day long, temperature, humidity, CO ₂ concentration, nutrient solution. Here, the light source includes a light source using sunlight and a light source using an artificial light source. As a light source, it is necessary to use an artificial light source that can be controlled under conditions necessary for plant growth in order to perform efficient and stable production. Current artificial light sources include high-pressure sodium lamps,
Metal halide lamps, fluorescent lamps and the like are used alone or in combination with sunlight. For example, a plant cultivation apparatus using a fluorescent lamp is disclosed in JP-A-2-60527. This is 400-70
700nm to 800n in the far-infrared region in 3 wavelength regions of 0nm
This is an apparatus for cultivating plants efficiently using fluorescent light having a wavelength range of m.

[0003]

The light source used in the conventional completely artificial light control type plant factory and the plant cultivation apparatus using the artificial light source accounts for a proportion of the electricity cost as light energy in the production cost. There was a problem of being big. In addition, since the wavelength range, irradiation amount, and irradiation time required for growth vary from plant to plant, it is necessary to be able to control for each wavelength in order to perform optimal irradiation, but the wavelength of light emission for high-pressure sodium lamps and metal halide lamps Cannot be limited to only the necessary wavelength range. In particular, during the high temperature period in summer, heat generated by infrared radiation that is inevitably generated beyond necessity has a significant effect on plants, so infrared radiation cut filters are installed and the frequency of operation of air conditioners is increased. Measures will be indispensable. On the other hand, in fluorescent lamps, the emission wavelength range can be selected depending on the composition of the fluorescent substance applied to the inner surface of the lamp bulb.However, the light energy ratio of each wavelength can be changed arbitrarily according to the type of plant and the growth stage. It is not possible to supply an optimum emission spectrum, and it is also difficult to blink only a specific wavelength or to vary the amount of light energy. In particular, a protein called phytochrome is involved in photomorphogenesis such as internode growth, leaf development, and flower bud formation. Phytochrome undergoes a reversible reaction at 650 nm and 730 nm. For example, in leaf vegetables, at 650 nm, petiole growth is suppressed and it becomes dwarf, and at 730 nm, the petiole elongates and becomes suspicious. It also affects germination and flower bud formation, and the morphogenesis is acted on by the light felt before entering the dark period. Germination and flower bud formation are inhibited by irradiating 730 nm light immediately before entering the dark period. In the natural world, there are some which use far-infrared light from a position where the sunlight at dusk is low to suppress branching of fruit and vegetables such as tomato. spinach,
In long-day plants such as chrysanthemum, when the light irradiation time per day is set to 12 hours or more, flower buds differentiate and leaf growth stops. Therefore, there was a problem that it was difficult to forcibly cultivate long-day plant leaf vegetables. Therefore, an object of the present invention is to provide a plant cultivation apparatus that enables forcing cultivation of long-day plants and short-day plants, and a cultivation method using the same.

[0004]

To solve the above-mentioned conventional problems, a plant cultivation apparatus of the present invention uses a fluorescent lamp for irradiating light of red, blue and green wavelengths and a light of far-infrared light wavelength. It has been found that the light is emitted by an emitting diode (hereinafter referred to as an LED). Separating the light source used for photosynthesis from the light source used for photomorphogenesis enables forcing cultivation of long-day plants and short-day plants.

The present invention comprises a fluorescent lamp of three wavelengths of red, blue and green and an LED of far-infrared wavelength, and adjusts the irradiation amount and the irradiation time of the fluorescent lamp and the LED of the three wavelengths according to the type of plant. It is a plant cultivation device that can be changed. In addition, a storage means for storing the growth data of various kinds of plants is provided, the growth conditions are read out from the storage means by selecting the plant to be cultivated, and the type of light, the irradiation amount, the irradiation time and the temperature are determined based on the growth data of the plant to be cultivated. This is a plant cultivation device that can control humidity, carbon dioxide concentration.

Liquid fertilizer control is performed by using the pH, electric conductivity, and liquid temperature information detected by the pH detector 16, the electric conductivity detector 17, and the liquid temperature detector 18 of the liquid fertilizer controller 19 as liquid fertilizer controller 1.
Send to 9. The liquid fertilizer control means 19 compares the control pH, control electric conductivity, and control liquid temperature of the growth information sent from the apparatus control means 24. The operation command of the liquid manure control means 19 is described below. In order to create a liquid fertilizer having a pH of 6.5 ± 0.5 and an electric conductivity of 1.0 ± 0.2 mS / cm in the liquid fertilizer section 23, the water supply section 20 and the liquid fertilizer raw material section 21 are turned on / off. The liquid manure control means 19 detects that the liquid manure part 23 has a small amount of liquid manure, and turns on the water supply part 20. Water supply unit 2
0 supplies tap water or well water to the liquid fertilizer section 23. The water quality of tap water and well water is pH 5.8 or more based on the water supply law and past experience.
It is known that the electric conductivity is 8.5 to 0.5 mS / cm. Simultaneously with the start of water supply, the pH detector 16 and the electric conductivity detector 17 operate. P above
H, the value of the electric conductivity is the value of the control pH and the control electric conductivity. The pH detecting section 16 and the electric conductivity detecting section 17 detect the values of pH and electric conductivity and send information to the liquid manure control means 19. The pH and electric conductivity information sent from the liquid manure control means 19 is compared with the control pH and control electric conductivity. In this case, the pH is in the range but the electrical conductivity is low,
The liquid fertilizer raw material section 21 is turned on. Liquid fertilizer raw materials should be made with high concentration of liquid fertilizer.

If the electric conductivity detecting unit 17 is low, the liquid fertilizer raw material unit 21 is turned on.
Then, the liquid fertilizer raw material is poured into the liquid fertilizer section 23 to increase the electric conductivity. At this time, since the pH decreases, the pH detector 16 also operates. When the pH falls below the control pH, the water supply unit 20 also turns on. The liquid fertilizer raw material section 21 and the water supply section 20 are supplied to the liquid fertilizer section 23 to prepare liquid fertilizer such that the control electric conductivity and the control pH become equal. When the liquid temperature is lower than the control liquid temperature in the growth information, the heater B22 is turned on to increase the liquid temperature. When the liquid temperature rises and the liquid temperature detected by the liquid temperature detecting section 18 becomes higher than the control liquid temperature, the device control means turns off the heater B22. It is known that the temperature of gas and liquid in a temperature-controlled device is generally lower than the temperature of the liquid, and a cooler must be installed because the temperature of the liquid never exceeded the temperature of the gas. Did not.

As described above, the device control means 24 is connected to the input means 2

By controlling the F, it is possible to efficiently forcibly cultivate a plant to be grown.

Next, using the above-described apparatus, the type and irradiation amount of light,
A description will be given of the fact that a suitable environment for each plant can be provided by performing plant cultivation while changing the irradiation time. The experiment was carried out at a constant temperature of 23 ± 5 ° C. from the time of sowing to the time of harvesting. Humidity was 90 ± 10% from sowing to true leaf formation and 75 ± 10% from true leaf formation to harvest. Liquid fertilizer was performed only from water from germination to true leaf formation, and supplied from the true leaf formation.
The liquid temperature of the feed fertilizer is 23 ± 5 ° C, and the pH is 6.5 ± 0.
5. The electric conductivity was 1.0 ± 0.2. These common conditions give the very general conditions found in vegetable and horticulture books. In the experiment, lettuce, salad vegetables, two kinds of spinach, and chrysanthemum were used as cultivated plants for comparison. Light irradiation was first cultivated by irradiating only the three-wavelength fluorescent lamp for 24 hours, and cultivating in the dark after irradiating an LED with a wavelength of 730 nm before entering the dark after irradiation of the three-wavelength fluorescent. An experiment was performed. The results are shown in (Table 1) (a) and (b).

[0023]

[Table 1]

The lettuce and salad vegetables could be cultivated only with fluorescent light and could be grown from sowing to harvest in 30 days. Spinach (Oriental) (Western) and Chrysanthemum are long-day plants. Fluorescent light alone caused flower bud formation and leaf growth stopped. Therefore, an experiment was performed by irradiating a light emitting diode having a wavelength of 730 nm before the dark period after irradiation with the three-wavelength region fluorescent lamp. Irradiation with a fluorescent lamp was performed at 12 hours / day and 15 hours / day, and with a 730 nm wavelength LED, experiments were performed at 15 minutes / day and 30 minutes / day after fluorescent lamp irradiation. The results are shown in (b) of (Table 1). Spinach (Oriental species) was forcibly cultivated by irradiating a fluorescent lamp for 12 hours / day + a light emitting diode for 30 minutes / day. Spinach (Western species) is fluorescent light 15 hours / day + light emitting diode 15-30 minutes /
Forcing cultivation was possible by day irradiation. The chrysanthemum could be forcibly cultivated by irradiation with a fluorescent lamp for 15 hours / day + a light emitting diode for 30 minutes / day. In all cases, the open-field cultivation required a cultivation period of about 70 days, but the cultivation period could be significantly reduced. This means that even in the case of leafy vegetables of a long-day plant, efficient forcing cultivation according to the plant can be achieved by controlling the irradiation time and the irradiation pattern of the three-wavelength region fluorescent light and the light-emitting diode having a wavelength of 730 nm by the light control means 3. it can.

Next, it will be described that effective forcing cultivation can be performed by changing the irradiation time of the light emitting diode for each plant. In the experiment, we tried to determine from what point during the growth of the cultivated plant the light-emitting diode irradiation was required. Light irradiation is performed with a three-wavelength range fluorescent lamp for 12 hours a day. The start of light-emitting diode irradiation is at the time of sowing, at the time of young leaf development, at the time of true leaf development, at the time of five true leaves, and at the time of ten true leaves. I shifted it gradually according to the growth of the plant. Irradiation of the light emitting diode was performed for 30 minutes immediately after the three-wavelength region fluorescent lamp was turned off. The results are shown in (c) of (Table 1). From these results, it was possible to suppress flower buds by irradiating from the early growth of long-day plants when young leaves or true leaves develop. The type, irradiation amount, and irradiation time of light for effective forcing cultivation are different for each plant, and it is understood that forcing cultivation can be performed according to this light irradiation method.

Next, an experiment was conducted on carbon dioxide, which is another factor of the photosynthetic reaction. A cultivation experiment was performed using lettuce while varying only the carbon dioxide concentration among the common items. The carbon dioxide concentration is increased only during the light irradiation time, and in the dark period, photosynthesis is not performed.
The information is stored in the carbon dioxide concentration control means 13 so as to stop Step 5. The results are shown in (Table 2).

[0027]

[Table 2]

From these results, it is possible to increase the weight per strain by increasing the concentration of carbon dioxide. From (Table 2), it was confirmed that both the above-ground living body weight and the above-ground part dry weight increased by 50% or more from 600 ppm to 1000 ppm, and the increase rate was 5% from 1000 ppm to 2000 ppm.
From 6% to 6%. If the concentration of carbon dioxide is increased, the weight of the strain increases, but about 1000 ppm is considered to be the most efficient.

The above experiment is repeated for other plants many times, and the conditions under which the morphogenesis of plants can be forcibly cultivated in a normal state are stored in the storage means 26. Input means 2
If a cultivated plant is selected from 5, the growth information of the plant is read from the storage means 26, and the plant environment can be controlled as described above, and forcing cultivation can be performed.

The storage means 26 is realized by a program, and is recorded on a recording medium such as a floppy disk and transferred, so that it can be easily implemented by another independent computer system. FIG. 2 is a diagram for explaining a case where this is carried out using a floppy disk.

FIG. 2A is a diagram showing an example of a physical format of a floppy disk as a recording medium body. A track is formed on the concentric circle from the outer circumference to the inner circumference, and is divided into 16 sectors in the angular direction. The program is recorded according to the allocated area.

FIG. 2B is a view for explaining a case for storing the floppy disk. From the left, a front view of the floppy disk case, a sectional view thereof, and a floppy disk are shown. By storing the floppy disk in the case in this way, the disk can be protected from dust and external impact and can be transported safely.

FIG. 2C is a diagram for explaining the recording and reproduction of a program on a floppy disk. By connecting a floppy disk drive to the computer system as shown in the figure, it becomes possible to record and reproduce programs on the disk. The disk is inserted into the floppy disk drive through the insertion slot and called. When recording, a program is recorded from a computer system to a disk by a floppy disk drive. To play,
A floppy disk drive reads the program from the disk and transfers it to the computer system.

In this embodiment, a description has been given using a floppy disk as a recording medium.
The same can be done using an optical disk. Further, the recording medium is not limited to these, and can be similarly implemented as long as the program can be recorded, such as an IC card or a ROM cassette.

[0035]

As is apparent from the above results, according to the present invention, the cultivation and cultivation of the selected plant can be cultivated under the recorded cultivation conditions, and the cultivation and cultivation of the selected plant can be performed with the artificial light source. Since cultivation is performed using light energy, production costs can be reduced, and the cultivation period can be shortened. In addition, since the size can be reduced, fresh vegetables can be supplied with the plants alive until just before using the vegetables.
