[0043] Figure 2 It is a parameter comparison chart of the detection results of the experimental group and the control group of the full-spectrum lighting method for plants in an embodiment. Detailed Embodiments

[0044] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0045] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or indirectly disposed on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.

[0046] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0047] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" and "several" is two or more, unless otherwise specifically defined.

[0048] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the implementable conditions of the present application. Therefore, they do not have a substantial technical meaning. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present application.

[0049] The present invention provides a full-spectrum lighting method for plants to solve the technical problem that the quality of naturally grown cannabis in the prior art cannot meet the requirements of industrial production and processing in large quantities.

[0050] In an exemplary technique, a plant growth lighting device simulates the principle that plants need sunlight for photosynthesis to supplement light for plants or completely replace sunlight. Currently, with the development of photobiomodulation technology, the lighting means for plant growth are no longer single. Different plants, or the same plant at different growth stages, can adopt different regulation measures and be irradiated with different spectra.

[0051] For example: In the early stage of plant growth, a large amount of blue light spectrum is required for the growth of plant roots, stems and leaves in photobiological research. In the later stage, for plants that harvest flowers or fruits, infrared or ultraviolet light is usually applied for short-term induction in photobiological research, which puts forward the requirement of multi-spectrum for plant growth lighting equipment.

[0052] Light quality refers to the composition of wavelengths in light that affect plant photosynthesis and photomorphogenesis. There is approximately 4% ultraviolet light, 52% infrared radiation and 44% visible light in sunlight (Moore et al., 2003). The solar spectrum is a full spectrum.

[0053] Plants mainly sense light of different wavelengths through photoreceptors. Currently, the known photoreceptors in plants can be divided into four categories: phytochromes that sense red and far-red light, cryptochromes and NPH1 (phototropin 1) that sense UV-A and blue light, and one or several unidentified UV-B receptors. These photoreceptors sense different light qualities, and then regulate and interact with each other through their differences to control the growth and development of crops, mainly including seed germination, root growth, stem growth, leaf growth, flowering, etc. Blue light is one of the main bands for plant photosynthesis, and at the same time, blue light plays an important regulatory role in the growth and development of plants. Although far-red light cannot directly act on photosynthesis, it acts as an environmental signal to regulate the growth and development process and metabolism of plants. The two main effects of far-red light on plants are mainly manifested in the shade avoidance effect and flowering induction effect of plants.

[0054] Currently, many research scholars have carried out research on light quality for plant growth and development. The light quality regulation for plant growth and development is mainly achieved by adjusting the ratio of red to blue light (R / B) and the ratio of red to far-red light (R / FR).

[0055] Based on the above exemplary technologies, the present application proposes an embodiment, a full-spectrum lighting method for plants, which is used for the flowering period of plants. The full-spectrum lighting method for plants includes: illuminating the whole life cycle of plants through a combined spectrum, and the functional bands of the combined spectrum include:

[0056] The first spectrum, the band range of the first spectrum is: 360 - 410 nm;

[0057] The second spectrum, the band range of the second spectrum is: 410 - 485 nm;

[0058] The third spectrum, the band range of the third spectrum is: 485 - 625 nm;

[0059] The fourth spectrum, the band range of the fourth spectrum is: 625 - 700 nm;

[0060] The fifth spectrum, and the wavelength range of the fifth spectrum is: 700 - 780 nm.

[0061] By providing the combined light of the above peak wavelength bands during the growth period of plants, the present invention can significantly increase the flower quantity and the quality of active ingredients of plants, is easy to operate, and can be produced on a large scale. The schematic diagram of the effect of the above spectral combination is as Figure 1 shown. By providing the combined light of the above peak wavelengths during the growth period of plants, the present invention can significantly increase the flower quantity and quality of hemp plants. Moreover, by controlling the spectral combination, in practical applications, it can be planted industrially, is easy to operate, and can be produced on a large scale, thereby solving the technical problem that the quality of naturally grown cannabis in the prior art cannot meet the requirements of industrial production and processing in large quantities.

[0062] Optionally, the peak wavelength of each spectrum in the combined spectrum is respectively:

[0063] The first spectrum: The peak wavelength is between 385 nm ± 5 nm;

[0064] The second spectrum: The peak wavelength is between 450 nm ± 5 nm;

[0065] The third spectrum: The peak wavelength is between 585 nm ± 10 nm;

[0066] The fourth spectrum: The peak wavelength is between 660 nm ± 5 nm;

[0067] The fifth spectrum: The peak wavelength is between 730 nm ± 5 nm.

[0068] The schematic diagram of the above spectral combination is as Figure 1 shown. By providing the combined light of the above peak wavelengths during the growth period of plants, the present invention can significantly increase the flower quantity and quality of hemp plants. Moreover, by controlling the spectral combination, in practical applications, it can be planted industrially, is easy to operate, and can be produced on a large scale, thereby solving the technical problem that the quality of naturally grown cannabis in the prior art cannot meet the requirements of industrial production and processing in large quantities.

[0069] In addition, by further determining other planting conditions matched with light through laboratory experiments, such as factors such as required water supply, soil, fertilization, etc., it can ensure that the spectral combination at this time fully maximally acts on the growth period of plants, achieving the purpose of optimally improving the quality of the planted plants.

[0070] Taking the flowering plant cannabis as an example to illustrate the beneficial effects of the present application:

[0071] Based on laboratory measurement data:

[0072] Control example

[0073] 1. Experimental materials:

[0074] Plant materials: Healthy cuttings of medicinal cannabis. Under consistent conditions,

[0075] Growth to plant type: Initial state, control 4 primary branches and 8 - 10 secondary branches, with a difference in plant height of less than 2 cm and a difference in stem diameter of less than 0.5 mm; after obvious inflorescence differentiation, no further trimming of the plant type is carried out.

[0076] The cultivation substrate is coconut coir: vermiculite = 1:1.

[0077] Environmental control: Temperature: 20 ± 2°C, relative humidity: 50 - 70%.

[0078] Comparative lighting: 1. Sodium lamp, 2. Fluorescent lamp, 3. LED lamp. It should be noted that the LED lamp is proportioned using the spectral combination claimed in this application for lighting.

[0079] Flowering stage: Flowering stage spectrum, 600 - 800 umol / m2, irradiated for 12 hours.

[0080] Nutrient solution: Flowering stage nutrient solution: EC = 2.5 ms / cm; pH = 5.5 - 6.0

[0081] 2. Experimental methods:

[0082] 2.1. During the flowering stage, illumination is carried out using a traditional plant growth sodium lamp, a fluorescent lamp, and an LED plant lamp with the above - mentioned spectral combination respectively. Obvious flower bud differentiation occurs about 1 - 2 weeks later.

[0083] 2.2. Pollen harvesting criteria:

[0084] 2.2.1. In the main branch inflorescence, when most male flowers are cracked and 1 - 2 are fully open, the male flowers can be harvested.

[0085] 2.2.2. Sampling: Continuously sample 10 cm of inflorescence starting from the top, 3 samples per plant. Manually separate the male flowers, place them in a sulfuric acid paper bag, seal it, and dry them in an oven at 25 ± 1°C.

[0086] 2.2.3. Sieve the dried male flowers through a 50 - mesh sieve to separate the pollen.

[0087] 2.2.4. Note: After harvesting the male flowers of each plant or separating a certain type of pollen, it is necessary to change gloves, pass through the air shower room, and disinfect with alcohol.

[0088] 3. Result comparison and analysis:

[0089] After each irradiation treatment, the pollen weight is as Figure 2 shown: Figure 2 The unit inflorescence refers to the continuously 10 - cm inflorescence starting from the top, specifically with a length of 10 cm;

[0090] Figure 2 It can be seen that during the flowering period of cannabis, the planting results are inconsistent in response to different irradiation environments. For fluorescent lamp irradiation, there is relatively less pollen amount, and there are obvious differences among other groups; for sodium lamp irradiation, there is relatively more pollen amount, and there are significant differences in pollen amount among groups; for LED irradiation with the above spectral combination, the relatively largest amount of pollen is produced, and there is basically no obvious difference among groups. From the perspective of the obtained pollen quality, LED irradiation with the above spectral combination has the best effect.

[0091] In one embodiment, the photon number ratio of the functional bands of the combined spectrum is as follows: the photon value ratio of the second spectrum to the first spectrum is 3.1, with a tolerance range of ±0.2; the photon value ratio of the fourth spectrum to the first spectrum is 5.4, with a tolerance range of ±0.2; the photon value ratio of the fifth spectrum to the first spectrum is 1.0, with a tolerance range of ±0.2.

[0092] Since different photon values represent different selected spectra, therefore, the spectral combination can also be determined according to the photon values, which can significantly improve the flower quantity and quality of hemp plants, is easy to operate, and can be produced on a large scale. It should be noted that there is no requirement for the photon value of the third spectrum, and any value can be taken without affecting the technical effect of this solution.

[0093] In one embodiment, the ratio of the peak value of the first spectrum, the peak value of the second spectrum, the peak value of the fourth spectrum, and the peak value of the fifth spectrum is: 9:20:20:3.

[0094] Among them, there is no requirement for the peak value of the third spectrum, and any value can be taken without affecting the technical effect of this solution. It should be noted that the above ratio can also be expressed as a percentage and can fluctuate within a range of ±5%.

[0095] Optionally, when the flowering plant is cannabis, the illumination time of the combination of spectra with the preset ratio is 12 - 16 hours.

[0096] By ensuring the above illumination time, it can ensure that the influence of the combined spectrum on the plant reaches the critical value within a certain time, achieving the best illumination effect. Further improving the growth of the parts of the plant that can be used for industrialization.

[0097] In one embodiment, the first spectrum is constructed by a single 385nm UVA LED light source;

[0098] The peak values of the second spectrum and the third spectrum are constructed by white LED lights with a specific color temperature, where the white light is generated by exciting phosphors with 450nm blue light;

[0099] The fourth spectrum is constructed by a single 660 nm red LED light source;

[0100] The fifth spectrum is constructed by a single 730 nm red LED light source.

[0101] Through the combination of the above LED light sources to form the spectrum combination scheme in this application, a certain continuous spectrum is finally formed to replace sunlight for irradiating plants. Compared with sunlight illumination, the LED light source combination has more photosynthesis spectra, and spectra that are not conducive to plant growth can be eliminated. Compared with traditional HID (High Intensity Discharge, high-pressure gas discharge lamp, mercury, sodium, gold, xenon lamp), its spectral distribution is more reasonable and effective, and the central temperature of the lamp is greatly reduced, which is beneficial to the growth and development of plants and helps to increase the content of active ingredients per unit time and per unit area of flower plants in plant factory production.

[0102] The present invention also provides an illumination device for flowering plants, including a memory and a processor. The memory stores a full-spectrum illumination program for plants. When the full-spectrum illumination program for plants is executed by the processor, the processor executes the steps of the full-spectrum illumination method for plants as described above.

[0103] It should be noted that since the illumination device for flowering plants in this application includes all the steps of the above full-spectrum illumination method for plants, the illumination device for flowering plants can also implement all the schemes of the full-spectrum illumination method for plants and has the same beneficial effects, which will not be elaborated here.

[0106] The UVA LED, the 660 nm red LED, and the 730 nm red LED respectively implement the first spectrum, the fourth spectrum, and the fifth spectrum;

[0107] The white LED implements the second spectrum and the third spectrum.

[0108] By combining the above LED light sources to form the spectral combination scheme in this application, a certain continuous spectrum is finally formed to replace sunlight for irradiating plants. Compared with sunlight illumination, the lighting device for flowering plants formed by the combination of LED light sources has more photosynthesis spectra and can eliminate the spectra that are not conducive to plant growth. Compared with traditional HID, its spectral distribution is more reasonable and effective, and the central temperature of the lamp is greatly reduced, which is beneficial to the growth and development of plants and helps to increase the content of active ingredients of flower plants per unit area per unit time in plant factory production.

The charging interface is connected to the power supply, and the power supply is respectively connected to the UVA LED, the 660nm red light LED, the 730nm red light LED, and the white light LED.

[0111] Through the above solution, the lighting can be guaranteed for a period of time after a power outage, avoiding the impact of sudden power outages or line failures on the growth of flowering plants.

[0113] Among them, the optical device can be designed according to the area that the actual lighting device needs to irradiate, so that the illumination is uniform, ensuring that the plants in the irradiation area can all achieve uniform illumination. In addition, the hoisting component can be used for hoisting the main body. Specifically, it can be a fixing member arranged at both ends or both sides of the main body, and the main body can be fixed through a hook, a rope, or a pull rope through the fixing member, so that the lighting device for flowering plants can be installed according to needs.
