  The photosynthesis effective photon flux density detected by the sunlight measuring photon sensor 37 and the cultivation photon sensor 39 is input to the light quantity control device 40 provided in the control room 15 or the like.

  The light quantity control device 40 drives the take-up type reflection device 34 to adjust the light environment of the genetically modified rice P based on the detection values of the solar light measurement photon sensor 37 and the photon photon sensor 39 for cultivation. While transmitting or blocking sunlight S, the inverter device 32 controls the amount of artificial light from the luminaire 31.

The situation and the like are input, and an optimum reference photon flux density value and a lower limit photon flux density value can be set according to the growth time of the transgenic rice P. Moreover, the cultivation management apparatus 42 integrates the detection values of the sunlight measurement photon sensor 37 and the cultivation photon sensor 39 input from the light quantity control unit 40 over time, and sunlight received by the growing genetically modified rice P.

Based on the detection value of the photon quantum sensor 39, the transmission and shielding of the reflecting material 35 by the winding type reflection device 34 and the light quantity (complementary light quantity) by the lighting fixture 31 are controlled.

  Below, adjustment of the light environment by the cultivation management apparatus 42 and the light quantity control apparatus 40 is demonstrated.

  First, the light environment is one of the most important elements for plants, and green plants grow by photosynthesis in the light environment and carbon assimilation using light energy. The effects of the light environment on plants can be broadly divided into two categories, one is the amount of light that affects the rate of photosynthesis (growth), and the other is the wavelength range that affects morphogenesis such as germination, flowering, and rooting. The light quality.

  In general, rice farming (one-phase cropping) is a cycle of seedling and raising seedlings from March to April, planting rice around May, heading, flowering and fruiting from June to July, and harvesting in September. The quantity is closely related.

  The wavelength range of solar radiation from the sun is about 300 to 2500 nm, the wavelength of 380 nm or less is ultraviolet, 380 to 780 nm is visible, and 780 nm or more is infrared. In relation to plant growth, a wavelength range of 400 to 700 nm is involved in photosynthesis with photosynthesis effective radiation, and 700 to 780 nm is involved in morphogenesis such as germination, flowering and rooting of plants with far infrared radiation.

  Then, when cultivating genetically modified rice P using sunlight, the relationship between the prediction of the total solar radiation amount that can be used in the cultivation room 11 and the necessary supplementary light amount (total solar radiation amount) was examined.

Total solar radiation by month:
As shown in FIG. 4, the monthly total solar radiation amount in Japan used the average value for 29 years from 1972 to 2000 in the statistical data of the Japan Meteorological Agency. Here, the total solar radiation amount is a solar radiation amount having a wavelength of about 300 to 2500 nm incident on a horizontal surface of a unit area, and the unit is represented by [MJ / m ² ].

The amount of solar radiation necessary for rice cultivation is 1000 [μmolm ⁻² s ⁻¹ ] with a PPFD (Photosynthesis Photoflux Density) proven in the PF-PJ test, and a light period of 12 hours is good. The PPFD was converted from the total solar radiation.

Cultivation conditions: Photosynthesis effective photon flux density on the cultivation bed surface PPFD = 1,000 μmolm ⁻² s ⁻¹ 12 hours light period PPFD to global solar radiation (instantaneous value) Conversion formula from I _global :
PPFD [μmolm ⁻² s ⁻¹ ] = 1.89888 × I _global [Wm ⁻² ]
Relationship between instantaneous value of total solar radiation and integrated value 1W = 1J / s
Calculation:
Total solar radiation (daily integrated value) = 1,000 μmolm ⁻² s ⁻¹ /1.8988×3,600 s / h × 12 h
= 22.8 MJ / m ²
Total solar radiation (time integrated value) = 1.9 MJ / m ²

  The relationship between the monthly total solar radiation amount and the solar radiation amount during rice cultivation is shown in FIG.

  FIG. 4 shows the monthly average of the daily solar radiation in Naha, Sapporo and Tokyo from 1972 to 2000, and shows the monthly change in the daily solar radiation.

In this FIG. 4, PPFD = 1000, rice cultivation in the case of 12 hours light season is 22.8 MJ / m ² , and considering 12 hours dark period, from March to October, Naha to Sapporo, The total amount of solar radiation is basically sufficient. In FIG. 4, the total solar radiation amount in Tokyo is lower than the total solar radiation amount in Sapporo.

  Thus, FIG. 5 shows the time variation of global solar radiation for four days with different seasons in Tokyo in 2009.

  FIG. 5 shows the time variation of the total solar radiation for four days showing the average values in March, August, September, and December in different seasons in Tokyo in 2009.

From FIG. 5, when PPFD = 1000, the amount of solar radiation for the 12-hour light period is 1.9 MJ / m ^{2. From} 8 o'clock to 16 o'clock, the total solar radiation amount exceeds PPFD = 1000. ing.

  However, in the genetically modified plant factory, as described with reference to FIGS. 2 and 3, a double structure of the cultivation room 11 and the daylighting room 12 is necessary to prevent gene diffusion. Here, it is composed of two rooms: a glass daylighting room 12 on the outside and a cultivation room 11 having a glass ceiling that transmits sunlight on the inside, and the amount of solar radiation that can be used in the cultivation room 11 is reduced by the sky factor. It is necessary to add correction to the total solar radiation in FIGS.

  Therefore, FIG. 6 shows the monthly total solar radiation amount when the sky rate is 50% in the cultivation room 11 when the sky rate is 50%.

  In FIG. 6, the total solar radiation amount in FIG. 4 is multiplied by 0.5 with a sky rate of 50%.

  Further, FIG. 7 shows a change with time of the total solar radiation amount (daily integration) obtained by multiplying the total solar radiation amount of FIG. 5 by 0.5.

  It can be seen that with this total solar radiation amount of 50% in Tokyo, there is no time for the total solar radiation amount to exceed PPFD = 1000, and supplementary light by artificial light is required in addition to sunlight.

  Here, the sky rate can be obtained by dividing the detection value of the cultivation photon sensor 39 by the detection value of the sunlight measurement photon sensor 37, and when the glass of the cultivation room 11 and the daylighting room 12 is soiled. In addition, the degree of dirt is also known from the sky rate obtained by these sensors 37 and 39.

  PPFD = 1000 is a reference photon flux density value when rice is cultivated with artificial light, but this reference photon flux density value is not constant from rice seedling to heading, flowering and fruiting. According to growth, PPFD = 1000 is required, and PPFD = 600 is sufficient for flowering and fruiting.

  Therefore, the cultivation management device 42 sets an appropriate reference photon flux density value and a lower limit photon flux density value according to the growth of the transgenic rice P, and the photon flux density detected by the sunlight measuring photon sensor 37 is lower limit photon. When the value is lower than the bundle density value, a shielding instruction is output to the light amount control device 40, and the winding type reflector 34 is driven to control the glass ceilings 30 and 29 to be shielded by the reflecting portion 35r of the reflector 35 and illumination. The instrument 31 is turned on, and the output voltage of the inverter device 32 is set via the light amount control device 40 so that the photon flux density value in the cultivation room 11 is equal to or higher than the reference photon flux density value from the detected value of the photon sensor 39 for cultivation. adjust.

  Moreover, the cultivation management apparatus 42 positions the transmission part 35s of the reflector 35 on the glass ceilings 30 and 29 of the cultivation room 11 when the photon flux density detected by the sunlight measurement photon sensor 37 is equal to or higher than the lower limit photon flux density value. The solar light S is taken into the cultivation room 11, and when the photon flux density value in the cultivation room 11 is equal to or higher than the reference photon flux density value from the detection value of the cultivation photon sensor 39, the lighting fixture 31 is turned off. When the reference photon flux density value is less than or equal to the lower limit photon flux density value, the supplementary light amount is controlled by the lighting fixture 31 for the shortage of sunlight S. At this time, the output voltage of the inverter device 32 is adjusted, and the lighting number control of the lighting fixture 31 to be lit is performed simultaneously.

  Although omitted in detail, the cultivation management device 42 controls the air conditioners 23E and 23W shown in FIG. 1, controls the temperature environment of the cultivation room 11, and supplies the cultivation shelf 27 with the cultivation. The liquid circulation amount is also controlled.

  In this way, the photon flux density is detected by the sunlight measuring photon sensor 37 and the cultivation photon sensor 39 so that the sunlight S is taken into the cultivation room 11 as much as possible during the growth of the genetically modified rice P, and the deficiency. By supplementing the light with the lighting fixture 31, the power consumption can be reduced to substantially half.

  Therefore, brown rice cultivated and harvested with normal artificial light costs about 80,000 yen per kg, but it can be made about 40,000 yen per kg by using sunlight together.

  The cultivation management device 42 stores date and time data, weather data (monthly and daily temperature and total solar radiation amount), temperature and solar radiation data according to growth, and genetically modified rice P during cultivation. From these, the reference photon flux density value and the lower limit photon flux density value are set, and the light environment of the transgenic rice P being grown is controlled based on the reference photon flux density value. By integrating the detected values of the photon sensor 37 and the photon sensor 39 for cultivation over time, it is possible to integrate the amount of sunlight and artificial light received by the transgenic rice P during growth. The reference photon flux density value and lower limit photon that can further reduce power consumption by evaluating the set value of the reference photon flux density value set by determining the relationship between the amount of light and the yield of brown rice harvested from genetically modified rice P Bundle density It is also possible to seek.

  As described above, in relation to the growth of rice, the wavelength range of 400 to 700 nm is involved in photosynthesis with photosynthesis effective radiation, and the wavelength range and spectral intensity of sunlight S are high in spectral intensity in the 400 to 700 nm band involved in photosynthesis. Has a distribution.

  The metal halide lamp used as the lighting fixture 31 has a spectral intensity distribution that varies depending on the halogen metal to be enclosed, but is preferably one in which sodium iodide, scandium iodide or the like having a spectral intensity peak in the 400 to 700 nm band is encapsulated. The light involved in morphogenesis, such as flowering and rooting of rice, is far-infrared radiation of 700 to 780 nm, and the light source of the luminaire 31 has a wavelength of 700 to 780 nm according to the flowering time of rice. More efficient illumination can be achieved by irradiating with a radiating sodium lamp, halogen lamp, LED or the like.

  Therefore, when adjusting the light environment with the lighting fixture 31, the cultivation management device 42 selects and turns on the lighting fixture 31 of the light source having various output radiation wavelengths according to the growth of the genetically modified rice P. Therefore, more efficient lighting can be performed.

  Thus, the present invention enables cultivation of genetically modified rice P in a short period of time by adjusting the optimal light environment and temperature environment according to the cultivation of genetically modified rice P. Thousands of seasons are possible.
