Description

  The present invention relates to a lighting device for irradiating light for photosynthesis used in a house for plant cultivation (hereinafter referred to as a house).

With regard to light for photosynthesis, it is more efficient to synthesize light by irradiating the plant with light that has been shredded (light with light and dark periods, hereinafter referred to as intermittent light) rather than continuous light. It has been known.
The present applicant pays attention to the good directivity of the light of the LED bulb as equipment for applying the above principle in the practice of house cultivation, and irradiates the plant with intermittent light as intermittent light. The following invention was proposed previously as an illuminating device.
(Japanese Patent Application No. 2010-061487, name “lighting device for plant cultivation by intermittent lighting”, hereinafter referred to as the lighting device according to the previous invention)
The lighting device according to the previous invention has been proposed as a lighting method that can be used with energy saving by a simple device using the light of an LED bulb (light source of a population), and this method is equivalent to sunlight. It is possible to achieve the amount of photosynthesis by the light of strong illuminance at low cost (small amount of electric power) using the light of the LED bulb (light source of the population).

Problems that the device tries to solve

The present invention proposes a more convenient specific mechanism as an embodiment of the method shown in the previous invention.
The problem to be solved by the present invention will be described with reference to FIG.
FIG. 1 shows the contents submitted as FIG. 7 in the application document of the previous invention (the part shown with numbers in FIG. 7 is shown with the numbers changed in FIG. In the description of the reference numerals, the changed part is added).
In FIG. 1, when the three LED bulbs 1w are turned on with the illumination unit 6 stopped, the effective irradiation surface on the ground surface 11 is S1, and the three LED bulbs 1w are turned on. In this state, the effective intermittent light irradiation surface on the ground surface 11 when the lighting unit 6 is rotated once in the rotation direction 5 on the horizontal surface about the center line 4 is S2.
Therefore, the intermittent light obtained by the method exemplified in the above invention has a light / dark cycle number twice as high as the rotation number of the illumination unit 6 (cycle number = 2 × rotation number). : Dark = area of S1: (area of S2−area of S1) Therefore, when using this intermittent light as light for photosynthesis, compared with using the light bulb 1w by direct continuous light irradiation It becomes extremely efficient light.
However, a continuous light portion remains at the center of S1.
In addition, the quality of the intermittent light is different depending on the cultivation temperature and the cultivation time of the cultivated plant, and when used for supplementary light, depending on the time zone and the weather (periods / second (number of periods per hour). (Hereinafter, referred to as the number of periods), a case where intermittent light having a light / dark ratio and light intensity) is required occurs.
Therefore, in the present invention, as one embodiment of the above-described inventive method for obtaining intermittent light by rotating the lighting unit 6 on a horizontal plane around the center line 4, the quality of intermittent light can be improved by a simple method. The problem was to create an intermittent light irradiation device that could be changed.

Means for solving the problem

Next, a means for adding a function for easily changing the quality of intermittent light will be described.
As means 1, the shape of the rectangular irradiation surface S1 shown in FIG. 1 is changed to a sector shape (fan-shaped irradiation surface S4 shown in FIG. 2).
FIG. 2 is a drawing in which a fan-shaped irradiation surface S4 (hereinafter also referred to as irradiation surface S4) is superimposed on the irradiation surface S1 and irradiation surface S2 shown in FIG. 1, and the radius of the irradiation surface S2 and the irradiation surface S4. Since the length L2 of one side coincides, the radius of the irradiation surface S2 is indicated by L2, and the diameter length of the irradiation surface S2 is indicated by L1 = L2 × 2 = L5. (Drawing displayed based on the dimension of the irradiated surface S4)
Hereinafter, the difference between the irradiation surface S1 and the irradiation surface S4 will be described with reference to FIG.
Irradiation surface S4 has a circular arc portion that overlaps a part of the circular arc of irradiation surface S2, the length of two sides is the radius (L5 / 2) of irradiation surface S2, and the vertexes (intersections) of the two sides are circular. Since it is positioned at the center point 14 of the surface S2, when the irradiation surface S4 is rotated on a horizontal plane around the center point 14 to irradiate light, the trace of the light (hereinafter referred to as the light trace). It coincides with the irradiation surface S2.
Therefore, even if the shape of the rectangular irradiation surface S1 is changed to the irradiation surface S4, the same surface S2 can be obtained as a range in which the intermittent light is irradiated.
However, the intermittent light made on the irradiation surface S1 is different from the intermittent light made on the irradiation surface S4, and the intermittent light made on the irradiation surface S1 has a light / dark ratio at a position near the center of the irradiation surface S2. Although the bright portion becomes large, in the case of intermittent light produced on the irradiation surface S4, the ratio of light and dark becomes uniform within the range of the irradiation surface S2, and in this respect, it becomes high-precision intermittent light.
In addition, since the irradiation surface S4 has a fan shape, the central portion does not become continuous light even when arranged radially at equal intervals (with a uniform angle apart) with respect to the center of rotation. By using many irradiation surfaces S4 and rotating while maintaining the relative position, even when the number of periods is changed, there is an advantage that intermittent light with high accuracy can be given to the cultivated plant.
At this time, the quality of the intermittent light received by the irradiation surface S2 is the number of periods of light and dark = (number of rotations / second (hereinafter referred to as the number of rotations) × the number of irradiation surfaces S4), and the light / dark ratio is: Dark = area of irradiation surface S4 × number of installed irradiation surfaces S4: (S2 area−area of irradiation surface S4 × number of installations of irradiation surface S4) It has the same property as intermittent light.
As shown in FIGS. 3 and 4, in the case of the method of installing two irradiation surfaces S4 on the irradiation surface S5 of circular intermittent light obtained by scanning the irradiation surface S4 (hereinafter referred to as irradiation surface S5) and three locations. The example in the case of the installation method was illustrated.
In the case of the method of obtaining the intermittent light by rotating the two irradiation surfaces S4 in FIG. 3, the quality of the intermittent light received by the circular irradiation surface S5 is the number of bright and dark periods = (the number of rotations × 2). The ratio of light and dark has the same property as intermittent light: light: dark = area of S4 × 2: (area of S5−area of irradiated surface S4) 2. (Further, when the light / dark ratio is calculated using the angle β between the two sides of the irradiated surface S4, light: dark = (2 × β) :( 360-2 × β).
In the case of FIG. 4, since the method uses three irradiation surfaces S4, the quality of the intermittent light received by the irradiation surface S5 in this case is bright / dark cycle number = (rotation number × 3). The ratio is the same as that of intermittent light: bright: dark = area of irradiated surface S4 × 3: (area of irradiated surface S5−area of irradiated surface S4).
As described above with reference to FIGS. 3 and 4, a plurality of fan-shaped irradiation surfaces S4 are used by disposing them at an equal angle around the center 14 of the circle of the irradiation surface S5. By changing and using the quantity of the irradiation surface S4 and the angle β between the two sides of the irradiation surface S4, different quality intermittent light can be given to the irradiation surface S5.

As means 2, an LED bulb for obtaining a fan-shaped irradiation surface S4 (hereinafter referred to as a fan-type illumination bulb) and a fan-type illumination bulb are set and rotated to irradiate the ground surface 11, and intermittent light is emitted. An apparatus for obtaining the irradiation surface S5 (hereinafter, an intermittent light irradiation apparatus according to the present invention) will be described.
FIG. 5 is a perspective view showing a fan-type illumination bulb.
The fan-shaped illumination light bulb is different from the LED light bulb used as household illumination in that the light irradiation part is a fan-shaped irradiation surface and the irradiated light creates a fan-shaped irradiation surface S4 on the ground surface 11.
Next, the mechanism of the intermittent light irradiation device according to the present invention, which is used by rotating a fan-type illumination bulb, will be described with reference to FIG.
In FIG. 6, the light bulb installation shade is a circular shade provided with a shelf 22 for setting a power distribution socket and a fan-shaped illumination bulb, a removable shelf 21, and a nut 20 for setting the shelf 21. The upper part is connected to the boss 18 and the rib 19.
The boss is connected to a rotating shaft, and the rotating shaft is connected to the output shaft of a motor (vertical flange motor).
FIG. 6 shows a situation in which two fan-type lighting bulbs are installed on the horizontal plane at 180 ° intervals on the horizontal plane.
In this situation, when the motor is operated, the light bulb installation shade rotates.
In addition, the power supply to the fan-type lighting bulb is supplied from the power cable to the plug of the fan-type lighting bulb through the socket from the slip ring mechanism installed in the middle of the rotating shaft. Regardless, stable power supply is possible.
Therefore, the intermittent light irradiation apparatus according to the present invention shown in FIG. 6 sets a fan-shaped illumination bulb on the shade for installing the bulb, drives the motor, and supplies power to the power cable, thereby intermittent light to the ground surface 11 below. It is an apparatus of the structure which can irradiate.

Effect of device

The previous invention makes use of the characteristics of the light reaction and dark reaction in the photoreaction, uses the irradiation surface S1 by a small light source, and moves it with a fast rotation, so that the cultivated plant in the wide irradiation surface S2 is light This is a method of obtaining the efficiency of intermittent light in photosynthesis by a method of artificially supplying light to a time zone that requires light.
In this method, compared to the case where continuous light or intermittent light is simultaneously irradiated on the entire surface of the wide surface S2, the light bulb and the lighting device as the light source become smaller, the energy consumption necessary for illumination is reduced, and strong light is economical. It can be used effectively, and it is an effective method.
However, in order to use intermittent light more effectively as a cultivation technique, appropriate intermittent light quality is required.
In the case of the mechanism using the intermittent light irradiation device according to the present invention shown in FIG. 6, there are the following characteristics in addition to the fact that the number of cycles can be changed by the number of rotations of the motor.
(1) The light / dark ratio of intermittent light can be changed by changing the specifications of the fan-type illumination bulb (by changing the angle β of the irradiation surface S4).
(2) It is possible to change the number of periods and the number of cycles of intermittent light by using a plurality of fan-type illumination bulbs set in a lamp installation shade.
This feature is a device that can irradiate the intended intermittent light by preparing several types of fan-type lighting bulbs and setting the required number of fan-type lighting bulbs to the shade for installing the bulb. is there.
As for the quality of intermittent light for efficient photosynthesis, the light intensity (illuminance) necessary for the bright reaction is required to be the same as that of natural sunlight. The above is necessary (the number of rotations is the same as the number of revolutions of a 2-pole motor using a 50 Hz power supply), but the intensity of light can increase the illuminance by narrowing the angle β of the irradiation surface S4. It is. (Due to changes in fan-type lighting bulb specifications)
In addition, since the number of cycles can be dealt with by the number of fan-type lighting bulbs installed, the intermittent light irradiation device according to the present invention shown in FIG. 6 can perform intermittent light with optimum qualitative conditions with energy-saving and simple operation. It is an effective device that can be applied to cultivation techniques.
On the other hand, when the light irradiated from the intermittent light irradiation device according to the present invention is used within a range where the afterimage effect can be applied, there is an advantage that it can be used for lighting of a house.

As for the shades for installing the bulbs, FIG. 6 shows an example in which two fan-type illumination bulbs are installed in contrast, but in actual use, there are many fan-type illumination bulbs installed in the shades for bulb installation. Design with possible locations.
In addition, when rotating the bulb installation shade with the rotating shaft, in order to reduce the load on the rotating shaft due to load imbalance (overhang load), install a load such as an unused fan-shaped lighting bulb, Balance and rotate.
In addition, it is convenient to add shift control to the motor as rotational power.

On the other hand, the kind of light used for plant cultivation is to mix and use red light (wavelength: light of about 650 to 750 nm) and blue light (wavelength: light of about 650 nm) as light for photosynthesis. However, since the slip ring mechanism shown in FIG. 6 allows a plurality of sockets attached to the shade for installing the bulb to be supplied with a plurality of electric powers having different voltages through the slip ring mechanism. There are many types of light bulbs, such as red light, blue light, and white light, and they are arranged in different colors depending on the type of plant, the state of growth, the brightness of the lighting, etc. Since an intermittent light irradiation device according to the present invention can be used with a fan-shaped illumination bulb of an illumination color, it is an effective usage method.
Next, the necessity of controlling the irradiation amount of the irradiation light and the mechanism for controlling the irradiation amount of the intermittent light irradiation apparatus according to the present invention will be described.

が発生する可能性も大きいことから、照射量の制御は光の効率的な利用の他、光呼吸の対策上の栽培技術としても、光の照射量の制御は必要な技術であり、本考案による間欠光照射装置においても、さらに利便性の高い装置となすために、照射量の制御を行う装備を付加することを提案するものである。
続いて、本考案の光の照射量の制御の方法について記述する。The amount of photosynthesis in conventional house cultivation (house using sunlight) is the same in the same house in the same type of cultivation plant and cultivation environment (CO2 concentration of outside air, intensity of sunlight, etc.) However, the amount of photosynthesis per unit time of plants varies greatly during the same day, even during the same day, generally in the morning and in the afternoon. Get smaller.
The cause of this change in photosynthetic efficiency is also due to the physiology of the plant, such as the required amount (required amount) of the receiver (fruits, roots, flowers, etc.) of the photosynthetic product (carbohydrate). Objectively, the decrease in the photosynthetic capacity seems to be due to the amount of photosynthetic products produced by the leaves exceeding the appropriate amount of translocation and excessive retention in the leaves.
In addition, the excessive accumulation of photosynthetic products in the leaves leads to an excessive leaf area (overgrowth), which is a bad result in cultivating plants for the purpose of harvesting fruits. In addition, in photosynthesis in an environment where the CO2 concentration in the vicinity of the leaves is low and the supply of CO2 is delayed, excessive light is used and there is an excess of the bright reaction regenerated product regenerated by the light reaction. The light reaction regenerated product reacts with oxygen to inhibit photosynthesis, causes light respiration, reduces the efficiency of photosynthesis, and is harmful to plant growth.
Therefore, the light for plant cultivation has a light reaction balanced with the dark reaction according to the appropriate amount of photosynthesis required by the plant, regardless of whether it is sunlight or artificial light, depending on the conditions of cultivation and cultivation. The method of adjusting the intensity and amount of light so that it can be applied and irradiating the cultivated plant is an efficient method of using light energy.
On the other hand, the intensity of the irradiation light of the intermittent light irradiation device according to the present invention needs to have the ability to irradiate light with intensity close to the illuminance in the house in fine weather in order to perform bright reaction efficiently and sufficiently. The house has no wind, so even if the CO2 concentration in the natural ventilation of the atmosphere (about 350-400 ppm) is maintained, the CO2 is taken in from the pores.

Therefore, it is necessary to control the irradiation amount of light as well as the efficient use of light as well as the cultivation technique for light respiration countermeasures. In order to make the intermittent light irradiation device according to, even more convenient, it is proposed to add equipment for controlling the irradiation amount.
Next, the method of controlling the light irradiation amount according to the present invention will be described.

The required amount of photosynthetic products and the photosynthetic capacity of cultivated plants change every moment depending on the type of cultivated plant, the state of growth, and the cultivation environment including light. Although it is difficult to change the intensity of the intermittent light emitted by the light irradiation device, in the present invention, focusing on the matters described in the following (1) and (2), the intermittent light irradiation according to the present invention is performed. The intermittent light emitted by the device is irradiated to the plant by repeating the operation in intermittent operation time of several minutes to several tens of long irradiation time zones, and the amount of light irradiated is integrated (time interval) It is solved by the method of controlling (by the average value of the integrated amount).
(1) In the photosynthesis, the leaves that undergo photosynthesis are objectively observed when the physiological phenomena of the plant such as the situation below the CO2 compensation point and the recovery situation, the photorespiration situation and the recovery situation, the situation due to the smooth photosynthesis, etc. The reaction of the photosynthetic products (light and dark) storage tanks and buffer tanks is adjusted and the reaction proceeds, and the photosynthesis products also have the same function in the flow path. Since it can be expected, when using this function, a certain amount of time delay is allowed in the control of the amount of light.
(2) Agricultural personnel have accumulated a lot of data such as the required amount of photosynthetic products and photosynthetic capacity of cultivated plants, depending on the intensity of light, the temperature in the house and the CO2 concentration, depending on the type and growth state of the cultivated plants. In addition, since it is possible to obtain information on the optimum control range of the light to be irradiated by tests in an actual house, it is possible to create highly utilized software relating to the integral control of the amount of light. What you can do.
Subsequently, a mechanism for intermittently irradiating the irradiation light of the intermittent light irradiation apparatus according to the present invention will be described.

The mechanism for intermittently irradiating the irradiation light of the intermittent light irradiation device according to the present invention is provided with a timer (hereinafter referred to as flicker function timer) that supplies intermittent power to the intermittent light irradiation device according to the present invention. Then, intermittent power supply is performed to perform intermittent operation.
FIG. 7 shows a mechanism for obtaining DC and AC intermittent outputs using two general-purpose flicker function timers.
In FIG. 7, the timer DC is in the range of the intermittent operation time T2 (intermittent operation time period T1 (total operation time, operation start time ta to operation stop time tb)). The timer has a function of intermittently supplying the same power as the input side to the load side only during the time period from the start time tc to the intermittent operation stop time td). Flicker function timer that can set time (tc, td) to an arbitrary time, and can also be set in units of hours, minutes, and seconds when setting energization time T4 and power failure time T3 as intermittent power It is.
The function of the timer AC is the same as that of the timer DC except that the power source to be used is an AC power source. (The general-purpose flicker function timer has a sufficiently large contact capacity on the output side and can supply power directly to the load side.
In the intermittent light irradiation apparatus according to the present invention shown in FIG. 6, when the timer DC and the timer AC are provided and used, the necessary DC power is supplied to the fan-shaped illumination bulb by the DC power from the external converter. Is input to the timer DC, and the output of the timer DC is connected to the power cable and the slip ring mechanism is energized to intermittently turn on / off the fan-shaped illumination bulb. Motor (in the case of an AC motor) The power is supplied to the vehicle by using the output power of the timer AC in synchronism with the intermittent operation of the fan-type lighting bulb.
Hereinafter, the example of the light irradiation which changed the operating condition of the morning and the afternoon by the intermittent light irradiation apparatus by this invention is shown. (In parentheses indicate timer operations)
Example of operation conditions and operation 1.1 The irradiation time of the day is assumed to be 10 hours of operation from 6:00 am to 4:00 pm.
(Operation from ta to tb, power supply for timer DC and timer AC, DC and AC are controlled by ON and OF)
Example 2.1 Within the irradiation time zone of the day, 4 hours from 0:00 pm to 4:00 pm is intermittent operation, and the period of intermittent operation is 15 minutes for energization time T5 and 5 minutes for power failure time T3. The operation is performed by setting the intermittent light irradiation time: irradiation stop time = 3: 1 and reducing the average irradiation amount of the intermittent light by 25%.
(Timer DC and timer AC are set, tc is set to 0:00 pm, td is set to 4:00 pm, energization time T4 is set to 15 minutes, and power failure time T3 is set to 5 minutes)
Above, Example 2. After setting, Example 1. The purpose can be achieved by operating the intermittent light irradiation device according to the present invention for a predetermined time. However, as in the above example, the intermittent irradiation light with a short period of several tens of seconds or less is further required as a condition. When the intermittent operation is performed only for 4 hours out of 10 hours, the amount of power required for the irradiation light is calculated to save about 10% of energy compared to the full-time operation.
In Japanese house cultivation for the purpose of harvesting fruits such as tomatoes, cucumbers and melons, 70-80% of the daily photosynthetic amount of cultivated plants is performed in the morning, and in the afternoon, the synthetic ability is reduced. When the amount of photosynthesis from the afternoon is large, the photosynthesis is poorly commutated, resulting in overgrowth of leaves and the like, resulting in a decrease in yield.
Therefore, in the case of healthy cultivated plants that give light and CO2 appropriately, it is more appropriate in terms of cultivation technology to reduce the dose of light from the afternoon, and light energy can be saved.

The intermittent light irradiation device according to the present invention is provided by providing a timer with a flicker function to the intermittent light irradiation device according to the present invention and supplying intermittent power to the intermittent light irradiation device according to the present invention. In all time periods that require irradiation in one day, according to the physiological situation of cultivated plants, periodic intermittent operation adapted to the divided time periods is performed, and in each section The mechanism for changing the irradiation amount of intermittent light to cultivated plants is an application that can exert energy-saving effects even when the type of artificial light for plant cultivation is continuous light (hereinafter referred to as continuous light for cultivation) Is possible.
FIG. 8 is a drawing showing a photosynthesis product of a plant cultivated in a house to a photosynthesis product by photosynthesis, and a flow showing the concept of its flow.
The chemical reaction from the product of photosynthesis to the production of sugar in the leaves to the distribution by the translocation of sugar is complex and has many unknown fields, but the actual results of plant cultivation have confirmed the photosynthesis to sugar translocation. If the process up to the flow is simply summarized as a conceptual virtual factory production, it can be represented approximately by the flow sheet shown in FIG. 8, so the concept of photosynthesis in house cultivation is explained with FIG. A-ku.
A. Photosynthesis is carried out in the chloroplast, but the reaction is a reaction that synthesizes carbohydrates by a light reaction that requires light energy and a dark reaction that requires CO ₂ (two reactions called the Calvin cycle). .
B) The light reaction receives a part of the dark reaction product synthesized by absorbing CO ₂ from the outside air in the dark reaction apparatus as a raw material, and reacts with the light reaction apparatus by the energy of light to react with the light reaction product. Then, it is supplied to the dark reaction apparatus.
C) The dark reaction uses the bright reaction product supplied from the bright reaction device and CO ₂ absorbed from the outside air as raw materials to produce a dark reaction product by reacting in the dark reaction device, and part of the dark reaction product is The raw material is supplied to the light reaction device and used as a raw material for the light reaction, and the remaining part is supplied as a raw material to the starch production device and saccharide production device in the chloroplast or the saccharide production device in the leaf.
D Sugars produced in the leaves (partially in chloroplasts) are transferred to roots, stems, flowers, fruits, etc. depending on the growth of the plant, and become nutrients.
The translocation of sugar to the roots, stems, flowers, fruits, etc. is carried out at night, etc., and this is a storage tank (light reaction shown in Fig. 8) due to accumulation in leaves, stems, etc. It works like a storage tank for starch, a storage tank for starch, and a storage tank for sugar.
However, once the ambient CO ₂ concentration drops to near the CO ₂ compensation point and the starch storage tank falls below the lower limit, the effect is so great that it takes a long time (several times) to restore the photosynthesis efficiency to normal. (Such as time).
G. If the balance between dark reaction and light reaction is lost, the light reaction product becomes excessive, and the light reaction storage tank overflows, photosynthesis is inhibited by photorespiration, which is an inhibitory factor in plant cultivation. It becomes.
In the current house, the amount of production by photosynthesis using sunlight and CO ₂ increases approximately proportionally to the intensity of light and the concentration of CO ₂ within the saturation range of light and CO _2. However, the practical saturation state is 30,000 lx by sunlight, and the CO ₂ concentration is about 1,500 ppm. However, the required amount of the product by photosynthesis of cultivated plants is set on the same day on a sunny day. by also physiological changes, since it comes to vary with time of day, not always all day also light and CO ₂ for cultivation, necessary to perform the cultivation while maintaining the concentration of strength and CO ₂ of light close to saturation without in accordance with the physiological requirements of cultivated plants to the product of photosynthesis can be supplied to without trouble smoothly, artificially control the light and CO ₂ (shown in FIG. 8, a light reaction tank, starch for storage tank, It is carried out quantitative control for maintaining the inventory of the kind for the reservoir to the proper value), a method of achieving efficient production of high quality with energy-saving.
With the above, the explanation using FIG. 8 is finished, but with the physiological change of the cultivated plant as the light administration method for photosynthesis, the entire time zone of the light administration target is divided for each passage of time, Technology that appropriately changes the dose of light corresponding to each section (within the time within the section, the irradiation apparatus is appropriately turned ON / OF to perform intermittent operation periodically to change the dose of light. ) Is an integral long time zone (minutes, units of time), so it is not limited to using the intermittent light for cultivation described above, and continuously irradiates cultivated plants. Even in the case of a functional continuous light plant cultivation irradiation device or in the case of using sunlight, it can be used as a method for achieving energy-saving, high-quality and efficient production as a house cultivation technique.
In addition, as a method of changing the dose of light for photosynthesis according to the administration time zone, the intermittent ratio and cycle when performing the intermittent operation of the light irradiation device are set in the light reaction tank by stopping for a long time. In order to eliminate the hindrance for cultivation such as loss due to a decrease in level, it is efficient to carry out in a short cycle (finely) of about several minutes to several tens of minutes.
In the current state of house cultivation, many of them are agriculture using primary hybrid (F1 species) seeds, and since it is an era that can be dedicated to the optimal cultivation for the physiological state of F1 species to be used for the time being, As for the administration of light for photosynthesis, the mechanism of the present invention that follows the physiological changes of back-cultivated plants (technology that appropriately changes the dose of light by dividing each time zone) is a first-generation hybrid (F1 species). ) Is fully utilized.
