The artificial light plant factory has the advantages of full sealing, low requirement on the surrounding environment, shortened plant harvesting period, water and fertilizer saving, no agricultural production, no waste discharge, etc.

Light is used as an important physical environment factor and plays a key role in regulating and controlling the growth and development and the substance metabolism of plants. It has become a common consensus in the industry that "one of the main features of plant factories is the fully artificial light source and the realization of intelligent regulation of light environment".

CN111174153A discloses a movable plant light supplement device, which comprises a light supplement unit and a guide rail unit, wherein the light supplement unit comprises a movable support, a light supplement lamp mounting rack arranged on the movable support, and a plurality of plant light supplement lamps arranged on the light supplement lamp mounting rack; the guide rail unit comprises a fixed bracket and a guide rail connected with the fixed bracket; the movable bracket is movably connected with the guide rail; the movable support is provided with side supporting legs which are respectively positioned at two sides of the guide rail, the tail ends of the side supporting legs are rotatably connected with walking wheels, and the walking wheels are abutted against the guide rail; one of the road wheels is connected with a driving device. Therefore, the number of required plant illumination lamps is reduced, the cost is reduced, and the plant illumination is flexibly and conveniently adjusted.

CN104302062B discloses an illumination control system and method for an intelligent plant factory using multi-color LEDs, which calculates the light emitting power ratios of multiple colors by detecting the light emitting powers of LED plant lamps with different colors, calculates and emits an illumination control signal according to the light emitting power ratios of the LED plant lamps with multiple colors and a preset reference light emitting power ratio, and the illumination control signal controls the light emitting powers of the LED plant lamps with different colors, so that the light emitting power ratios of multiple colors are matched with the reference light emitting power ratio to meet the illumination requirements of plants at different growth stages. The luminous power of the LED plant lamps with various light colors is continuously detected on line in real time, and the luminous power of the LED plant lamps with various light colors is adjusted by combining the illumination requirements of plants at different growth stages, so that the plants in a plant factory are in the optimal growth state, the energy utilization rate of the plant factory is improved, and energy is saved.

When plants are cultivated in an existing plant factory, a plane framework and a three-dimensional framework are usually adopted for a plant cultivation frame, the plane framework occupies a large amount of space, so that effective space above the plane framework cannot be fully utilized, meanwhile, a large amount of light supplementing equipment for assisting plant growth is usually matched based on the plane framework, the production cost is undoubtedly increased by the large amount of light supplementing equipment, and in order to solve the problem, the movable light supplementing equipment is utilized in the prior art, but the movable light supplementing equipment cannot ensure that plants at various plant positions in a plant cultivation area can receive light rays with proper proportion and intensity and uniform illumination; for the three-dimensional structure, although the space utilization rate can be effectively increased, when the three-dimensional structure is matched with corresponding light supplement equipment for irradiation, a means that light sources are arranged on each planting layer or the light supplement equipment can move in the vertical direction is arranged on the basis of the three-dimensional structure is not used, but the problems that light irradiation has an illumination blind area and the light irradiation provided by the light supplement equipment is not uniform exist. Secondly, when the light supplement device is used for growing and irradiating plants, the light sources are usually designed in a mode that the light sources with different emission wavelengths or light-emitting colors are combined according to a certain gap and can be independently driven through electric power, but the mode that in actual irradiation, the actual illumination which can be received by various planting positions is different based on the distance difference between the various planting positions and the light sources when the light sources with different emission wavelengths are combined and irradiated is ignored, so that the light source arrangement method adopting a similar equidistant mode cannot meet the requirements of the plants at different positions on light, namely, the various planting positions cannot receive the light with effective uniformity, proper intensity and reasonable proportion. Thus, there remains a need in the art for at least one or several aspects of improvement.

In the description of the present invention, it is to be understood that "first direction" refers to a direction parallel to the ground or the X axis, and "second direction" refers to a direction perpendicular to the ground or parallel to the Y axis.

The invention provides a plant factory and a plant cultivation method, which can comprise one of the following components: a plurality of cultivation devices 1 for bearing plants to cultivate plants and a management system 2 for adjusting the cultivation environment of the plant factory in real time based on plant species, growth cycle and development level.

According to a preferred embodiment, the cultivating device 1 at least comprises a plant cultivating frame 10, wherein the plant cultivating frame 10 may comprise a shaft body 101, at least one first track 102 spirally distributed on the circumferential outer side surface of the shaft body 101, and a plurality of second tracks 103 distributed on the circumferential outer side surface of the shaft body 101 and arranged along the axial gap of the shaft body 101. Preferably, the end of the shaft 101 near the ground is defined as a ground proximal end 101a, and the end thereof away from the ground is defined as a ground distal end 101 b.

According to a preferred embodiment, as shown in fig. 1, the first track 102 is configured as a spiral track extending in the axial direction of the shaft body 101 and formed in such a manner as to spirally spread in a substantially circular shape starting from the axis of the shaft body 101. Preferably, the shape having the spiral diffusion may include a regular spiral and/or an irregular spiral as long as it is satisfied that each point on the curve extending in the prescribed direction takes a posture in which the perpendicular distance from the shaft body 101 gradually increases or decreases.

According to a preferred embodiment, the first track 102 extends axially around the shaft 101 to form a plurality of cultivation layers with different layer spacing. The range of at least one cultivation layer can be defined as a complete plane, a half plane or other selection formed by the first rail 102 surrounding the shaft 101, which mainly depends on the planting requirement of each cultivation layer, because the plants cultivated by each cultivation layer can be the same or different, and the plants can have at least some difference in appearance based on the growth forms that different plants may have in different growth cycles, and the layer spacing between each cultivation layer and the range defined by the cultivation layer are adjusted based on the type of the plant to be planted in order to adapt to the growth characteristics and growth performance of different plants to promote their growth and development and thus make them show the most excellent growth state. Preferably, not only the plants planted on the respective cultivation layers are maintained in an excellent growth state, but also the limited space between the respective cultivation layers is fully utilized based on the design structure of the first rail 102.

According to a preferred embodiment, the first track 102 is configured to extend along the distal end 101b of the shaft body 101 towards its proximal end 101a in a manner shaped around the shaft body 101 with the shaft body 101 as a centre of rotation, and the first track 102 assumes a geometrically stepped and/or proportionally increasing attitude around the radius or perpendicular distance thereof from the shaft body 101 in a direction along the distal end 101b of the shaft body 101 towards its proximal end 101 a. Alternatively, at least a portion of the first track 102 on the side closer to the distal end 101b may have a smaller radius of curvature or a shorter perpendicular distance from the shaft body 101. While at least a portion of the first track 102 near the ground-proximal end 101a has a larger curve radius or a larger vertical distance from the axis 101, which is considered that the plants at the ground-distal end 101b are closer to the light source and receive more or stronger light than the plants at the bottom. While the plants at the proximal end 101a are further from the light source and receive less or weaker light than the top plants. Preferably, either fancy plants or plants with long lighting periods can be planted in at least a portion of the orbit relatively close to the remote ground end 101b, or plants with smaller sizes can be planted around a radius based on a smaller curve; while plants with low light tolerance or short light cycles are planted in at least a portion of the orbit relatively close to the ground-proximal end 101a, or plants with larger shapes are planted around a radius based on a larger curve. Further, the inner side of the first rail 102 is configured as a first channel 1020 extending along the surrounding direction thereof and matching the shape of the first rail 102, the first channel 1020 being configured for carrying, cultivating plants and transporting nutrient solution.

According to a preferred embodiment, as shown in fig. 3, the circumferential outer side surface of the shaft body 101 may be provided with a plurality of first rails 102. Specifically, the plurality of first tracks 102 may be disposed on the circumferential outer side surface of the shaft body 101 in such a manner as to spirally surround each other in the first direction and/or the second direction with a certain clearance. Alternatively, the gaps between the first rails 102 in the first direction and/or the second direction may be the same or different, depending on the type of plants being cultivated by the plant cultivation shelf 10, and the gaps between the first rails 102 are adjusted to allow the plants at each planting point in each cultivation layer on the first rails 102 to receive suitable light and grow to the maximum extent according to the growth characteristics thereof, in order to adapt to the growth forms of different plants or the requirements for light, as shown in fig. 6. Preferably, the first tracks 102 are arranged in a manner that the whole volume of the first tracks 102 shows geometric progression and/or equal proportion increase in a direction away from the shaft body 101 along the first direction by taking the shaft body 101 as a center, or the curve radius of at least part of the tracks of the first tracks 102 in the same plane shows geometric progression and/or equal proportion increase in posture. And the overall volume of the first rail 102 closer to the shaft 101 is smaller than the overall volume of the first rail 102 farther from the shaft 101, that is, when viewed from above along the second direction, the cultivation layers constructed by the first rails 102 are in a staggered posture, as shown in fig. 6. Preferably, the plants on different cultivation layers of the plurality of first tracks 102 staggered with each other are exposed to the illumination to the maximum extent based on the phototaxis of the plants during the growth, and receive the illumination with reasonable proportion and appropriate intensity, so that the excellent growth state such as the vertical upward growth can be maintained to the maximum extent.

According to a preferred embodiment, at least part of the circumferential outer side surface of the shaft body 101 is provided with a substantially annular second lighting assembly 21 b. The distal end 101b of the shaft body 101 is provided with a plurality of movable substantially linear first illumination assemblies 21 a. Specifically, the first illumination assembly 21a may be foldable, which considers that when the plant is irradiated by natural light or sunlight without additional supplementary illumination device, the first illumination assembly 21a located above the first track 102 may shield at least a part of the plant below the first illumination assembly, so as to prevent a part of the sunlight from irradiating the surface of the shielded plant, and thus the plant may show slow growth and the like compared with other plants, and therefore the first illumination assembly 21a may be folded towards the direction close to the shaft 101 manually or based on an external driving manner, so as to reduce the blockage of the illumination light, and thus a plurality of plants located on the first track 102 may receive uniform light to perform normal growth and development. Or the at least one first lighting assembly 21a is folded towards the direction close to the shaft body 101 through a manual mode or an external autonomous driving mode, that is, the first lighting assembly 21a and the shaft body 101 are in a state of being parallel to each other, so that the influence on the growth and development of the plants due to the fact that the first lighting assembly 21a forms irradiation resistance on partial light is eliminated.

According to a preferred embodiment, the second lighting assembly 21b is capable of illuminating the plants on the first track 102 in a complementary manner by emitting a substantially annular light radially outwards of the shaft 101, centered on the shaft. Specifically, when the plants below the first track 102 are subjected to growth illumination by the first illumination assembly 21a above the first track, besides the ideal state, the partial plants inevitably cause light blockage to each other during the growth process, for example, the plants relatively close to the top cause light blockage to the plants below; or due to the rotating and/or swinging illumination of the first illumination assembly 21a, when the plants on the first track 102 are illuminated, at least a part of the illumination blind area exists, for example, at least a part of the first track 102 relatively close to the shaft body 101 may be blocked by the first track 102 at the periphery thereof. Therefore, based on this situation, at least a part of the plants cannot receive effective light by using the leaves thereof to perform photosynthesis required for growth and development, the second lighting assembly 21b can be used to cooperate with the first lighting assembly 21a to perform supplementary lighting on the plants on the first track 102 from the opposite inner side, i.e. when the ideal light full coverage cannot be satisfied by using the first lighting assembly 21a, the plants can be irradiated from multiple angles by cooperating with the second lighting assembly 21 b. Preferably, the illumination intensities of the second illumination module 21b and the first illumination module 21a may be the same or different from each other in consideration of the phototaxis of plant growth, in order to allow the plants on each cultivation layer to grow in the most excellent growth posture, and in addition to providing good quality, to make full use of the planting space on each first rail 102 and the cultivation layer thereof. Further, the ratio of the light intensities of the second lighting assembly 21b and the first lighting assembly 21a can be adjusted according to the real-time growth state of the plants on each cultivation layer. Specifically, the real-time growth state of the plant can be detected by, for example, an image pickup device. For example, when the plant on the first track 102 assumes a growing posture approaching the curvature of the shaft body 101, the ratio of the light intensities of the first lighting assembly 21a and the second lighting assembly 21b may be increased appropriately to keep the plant in a vertically growing posture as much as possible.

According to a preferred embodiment, the first lighting assembly 21a can be used to illuminate the plants on the first track 102 in a substantially parallel position with respect to the ground. Or the plant on the first rail 102 is subjected to growing irradiation in a state of being parallel to a generatrix of a substantially conical structure formed by the first rail 102 being wound, as shown in fig. 9. Preferably, the first illumination assembly 21a is rotatable around the shaft 101 by a rotating assembly disposed at the distal end 101b of the shaft 101 to provide a substantially truncated cone-shaped and/or conical light coverage area to the plants on the first track 102. The specific structure of the rotating assembly is not limited, and a structure that can rotate the second illumination assembly 21b around the shaft body 101, which is commonly used in the related art, may be employed. Preferably, compared with the static light source with a larger light coverage area in the prior art, the first illumination assembly 21a in the embodiment of the present invention is configured as a dynamically movable linear light source, so that the light emitted by the first illumination assembly 21a is more concentrated, and thus the corresponding illumination intensity is improved, and the corresponding illumination blind area is greatly reduced by the dynamic light source, so that more blades can receive the light, and the blocking effect of the cilia on the blade surface on the light is also greatly reduced, so that other parts of the blade, such as the light sensing part on the back side of the blade, can also be irradiated with more light, which is more favorable for the uniform growth of plants.

According to a preferred embodiment, the specific pose of the first lighting assembly 21a is manually or externally driven when it illuminates the plant located therebelow, and the adjustment of the specific pose is based on the monitoring of the plant growth status or plant growth environment by an external device for external autonomous driving. Further, the monitoring of the plant growth state can be accomplished by detecting the area of the plant leaves and the plant growth height through a camera device, which is commonly used in the prior art; the plant growth environment can be monitored by using sensors to detect air humidity, temperature, illumination intensity, CO in the plant growth area₂Or O₂Concentration, etc.

Preferably, after the image capturing device captures the plant growth state image on the cultivation layer positioned at the upper end of the first rail 102, the external control device or the central control device analyzes the image and compares the image with the standard data in the database, when, for example, the area of the plant leaves reaches a preset growth threshold, the external control device or the central control device may drive the first lighting assembly 21a to be unfolded away from the shaft body 101, and at this time, the plant on the lower cultivation layer may not meet the corresponding growth threshold, since the distance between the rear end of the first illumination module 21a and the lower cultivation layer is increased, the intensity of light is reduced, the light emitting intensity of the light emitting elements of the first illumination assembly 21a on the side away from the shaft body 101 can be enhanced by external driving and the light emitting intensity of the light emitting elements of other sections of the first illumination assembly 21a can be properly adjusted to adapt to the change of the illumination intensity caused by the change of the optical distance.

Or, after the image of the plant growth state on at least part of the cultivation layer of the first track 102 is captured by the camera device, the image is analyzed by the external control device or the central control device and compared with the standard data in the database, when, for example, the area of the plant leaf reaches a preset growth threshold, the external control device or the central control device can drive the first lighting assembly 21a to be folded and/or unfolded in a direction close to and/or away from the shaft body 101, and drive the first lighting assembly 21a to rotate through the rotating assembly, and for plants in other areas which do not meet the corresponding growth threshold, the requirement of the plants in the corresponding area for the growing light can be met by adjusting the light intensity of the light emitting elements in different sections of the first lighting assembly 21a based on the external drive.

Preferably, the sensor detects CO in at least a portion of the area of the first track 102₂Concentration, O₂After the concentration or the concentration ratio, the external control device or the central control device analyzes the numerical value and compares the numerical value with standard data, and when CO is in the condition of concentration or concentration ratio, the numerical value is analyzed by the external control device or the central control device and compared with the standard data₂Concentration, O₂When the concentration or concentration ratio thereof reaches a preset threshold, e.g. when CO₂Concentration below a certain threshold and O₂If the concentration is higher than a certain threshold or the concentration ratio is higher than a certain threshold, the net photosynthesis of the plants in the area can be considered to be stronger, and the folding and/or unfolding of the first lighting assembly 21a can be adjusted based on the driving of the external control device or the central control device, and the first lighting assembly 21a is driven to rotate by the rotating assembly to reduce the illumination corresponding to the area meeting the preset threshold, and/or enhance the illumination not meeting the preset threshold.

According to a preferred embodiment, the first illumination assembly 21a and the second illumination assembly 21b may be formed by a combination of several independently drivable light emitting modules 210. Specifically, each light emitting module 210 is configured to be formed by combining several light emitting units that can be independently driven and have different emission wavelengths or emission colors. Further, each light emitting module 210 is provided therein with a first light emitting unit 210a, a second light emitting unit 210b, and a third light emitting unit 210 c.

Alternatively, the first light emitting unit 210a is configured as a red LED light source having an emission wavelength of 620nm to 760 nm. The second light emitting unit 210b is configured as a blue LED light source having an emission wavelength of 400nm to 450 nm. The third light emitting unit 210c is configured as a green LED light source having an emission wavelength of 492nm to 577 nm.

Preferably, the first light emitting unit 210a, the second light emitting unit 210b and the third light emitting unit 210c with different emission wavelengths are independently driven to provide the plants on the first rail 102 with light required to meet different growth requirements thereof. For example, a blue LED light source having an emission wavelength of 400nm to 450nm may be used to promote the growth of plant leaves and stems, a red LED light source having an emission wavelength of 620nm to 760nm may be used to promote flowering and fruiting of plants, and a green LED light source having an emission wavelength of 492nm to 577nm may be used to delay leaf senescence.

Preferably, a composite light ray similar to a natural light ray may be compositely formed by simultaneously driving the first light emitting unit 210a, the second light emitting unit 210b, and the third light emitting unit 210c, and a light quality of the composite light ray may be changed by adjusting an intensity ratio of each light emitting unit to change an irradiation effect on a plant so that it can represent an optimal growth state based on an excellent irradiation environment. In particular, the red light fraction can be suitably enhanced to reduce the blue light fraction, not only because an excessively high content of blue light may retard or inhibit plant growth, hinder its synthesis of carbohydrates, etc., but also because blue light is somewhat harmful to the human eye. For example, for some leaf vegetables, the red-blue light ratio required in the seedling stage has a certain requirement, and the red-blue light ratio can be properly adjusted to increase the seedling quality of the corresponding leaf vegetables in the seedling stage and prevent the corresponding leaf vegetables from growing in vain.

According to a preferred embodiment, the plurality of first tracks 102 are configured to extend from the distal end 101b of the shaft body 101 to the proximal end 101a thereof in a manner of being formed around the shaft body 101 with the shaft body 101 as a rotation center, and the curve of the first tracks 102 in the direction along the distal end 101b of the shaft body 101 to the proximal end 101a thereof presents a geometric progression and/or an equal proportional increasing posture around the radius or the perpendicular distance between the radius and the shaft body 101, so that, in order to adapt to the illumination requirement generated based on the design structure of the first tracks 102, the light emitting module 210 formed by a combination of a plurality of light emitting units which can be driven independently and have different emission wavelengths or emission colors in the first illumination assembly 21a is configured to: the mounting gaps of the first light emitting unit 210a, the second light emitting unit 210b and the third light emitting unit 210c in each light emitting module 210 are increased or decreased in equal proportion to each other as viewed in the arrangement direction of the substantially linear first lighting assembly 21a, as shown in fig. 8. That is, the mounting gap between the first light emitting unit 210a, the second light emitting unit 210b, and the third light emitting unit 210c in the light emitting module 210 relatively close to the shaft body 101 is larger than the mounting gap between the first light emitting unit 210a, the second light emitting unit 210b, and the third light emitting unit 210c in the light emitting module 210 relatively far from the shaft body 101. Preferably, the specific installation gap can be obtained by calculating parameters such as a suitable photon flux and a photon flux density according to a specific design structure of the first track 102 through a formula.

According to a preferred embodiment, the mounting gaps between the light emitting elements in the light emitting modules 210 are different from each other in consideration of the illumination effect of the light quality combination, ratio and intensity of the first lighting assembly 21a on the plants on the first rail 102 located therebelow. Specifically, when the light emitting elements with different emission wavelengths are alternately arranged and emit light simultaneously, at least a portion of the light generated by the light emitting elements is overlapped, and similarly, at least a portion of the light generated by the light emitting module 210 composed of the light emitting elements is also overlapped, so that the light in the overlapped region has a higher light quantum flux, and the light in the other non-overlapped region has a lower light quantum flux, and the non-uniform emitted light is not favorable for plant growth, especially corresponding to the spiral multilayer structure of the first track 102 in the present invention.

According to a preferred embodiment, when the first lighting assembly 21a illuminates the plants on the cultivation layers of the first track 102 below the first lighting assembly based on the horizontal posture of the first lighting assembly, if the plants are illuminated by the same installation gap and light illumination intensity, the effective illumination available to the plants on each cultivation layer is different based on the light distance of the plants on each cultivation layer and the first lighting assembly 21a in the second direction, and particularly, the illumination which can be received by the plants on the cultivation layer at the bottom of the first track 102 is more limited. Further, since the first track 102 in the present invention presents a geometric progression and/or an equal proportion of increasing posture around the radius of the curve in the extending direction from the far end 101b to the near end 101a of the shaft 101 or the vertical distance between the first track 102 and the shaft 101, in order to adapt to the change of the first track 102 around the radius to satisfy the uniform illumination of the plants in each cultivation layer, the installation gap between the light emitting elements in the first lighting assembly 21a is gradually reduced along the geometric progression and/or the equal proportion of increasing radius around the curve in the extending direction from the far end 101b to the near end 101a of the shaft 101, that is, the effective illumination received by at least a part of the plants closer to the far end 101b of the first track 102 is stronger than the first lighting assembly 21a, so the installation gap between the light emitting elements corresponding thereto is larger, the light source device can reduce the higher light quantum flux generated by partial light superposition, avoid the plants at the position from receiving too strong illumination, prevent the waste caused by the redundant light at the position from causing the waste to ensure that the light cannot be effectively utilized, also prevent the inhibition effect of the too strong illumination on the growth of the plants, simultaneously reduce the superposed light generated by each light-emitting element based on the radiation diffusion of the light and enlarge the range which can be covered by the light.

According to a preferred embodiment, the light intensity of at least a part of the plants irradiated on the far end 101b of the first track 102 by the composite overlapping of the light emitting elements 21a and the light emitting elements in the light emitting module 210 close to the shaft 101 is reduced, and the light generated by the light emitting elements can be more irradiated on the plants on the rest cultivation layers, for example, the plants on the cultivation layers far away from the far end 101b, so as to reduce the proportion of redundant light irradiated on at least a part of the plants on the far end 101b and increase the proportion of effective light irradiated on at least a part of the plants on the rest cultivation layers. On the other hand, the mounting gap of each light emitting element in the light emitting module 210 at the end of the first lighting assembly 21a far away from the shaft 101 is the smallest, and similarly, at least a part of the plants closer to the ground end 101a of the first track 102 are farther from the first lighting assembly 21a, the effective light which can be received by the LED is weak, so that the installation gap of the light-emitting elements corresponding to the position is small, so as to increase the higher light quantum flux generated by the superposition of partial light rays, avoid the overlow composite light received by the plant, increase the light required by the plant to increase the utilization rate of the plant to the light rays, and also avoid the inhibition effect of the overlow light intensity on the growth of the plant, meanwhile, the radiation diffusion based on light increases the amount of overlapped light generated by each light emitting element to reduce the dispersion of light so that more light can be concentrated at the position to provide stronger illumination.

According to a preferred embodiment, the light intensity of at least a part of the plants irradiated on the far end 101b of the first track 102 by the composite overlapping of the light emitting elements 21a and the light emitting elements in the light emitting module 210 close to the shaft 101 is reduced, and the light generated by the light emitting elements can be more irradiated on the plants on the rest cultivation layers, for example, the plants on the cultivation layers far away from the far end 101b, so as to reduce the proportion of redundant light irradiated on at least a part of the plants on the far end 101b and increase the proportion of effective light irradiated on at least a part of the plants on the rest cultivation layers. Preferably, based on the arrangement manner of the installation gaps of the light emitting elements in the first lighting assembly 21a, when the plants on the first track 102 are grown and irradiated by adjusting the placing posture of the first lighting assembly 21a, the variation of the illumination intensity caused by the variation of the light distance can be adapted by adjusting the light source ratio and the intensity of the light emitting elements in different sections of the first lighting assembly 21a based on the distance between the first lighting assembly 21a and the plants on the cultivation layers. For example, when the light emitting module 210 at the tail end of the first lighting assembly 21a is close to the plant on the bottom cultivation layer of the first track 102, the light emitting intensity of each light emitting element in the light emitting module 210 in the area can be correspondingly reduced to provide a suitable illumination intensity, or the ratio of each light emitting element can be appropriately adjusted to provide a suitable light source ratio based on the growth characteristics of the plant on the bottom cultivation layer.

According to a preferred embodiment, the mounting gaps between the light emitting units in the light emitting modules 210 of the second lighting assembly 21b are arranged in the same manner as the first lighting assembly 21 a. Specifically, in the extending direction along the distal end 101b of the shaft body 101 toward the proximal end 101a, the mounting gaps between the light emitting units in the light emitting modules 210 of the second lighting assembly 21b are reduced in order. In this way, the mounting gap of each light emitting element in the light emitting module 210 of the second illumination unit 21b on the side close to the distal end 101b in the axial direction of the shaft body 101 is large, and the mounting gap of each light emitting element in the light emitting module 210 of the second illumination unit 21b on the side close to the proximal end 101a in the axial direction of the shaft body 101 is small.

Preferably, the radius of the portion of the track on the side of the first track 102 close to the far end 101b of the shaft 101 is smaller or the portion of the track is closer to the shaft 101, so that the effective light received by the portion of the track is greater or stronger than the effective light received by the portion of the track below the portion of the track, and therefore, in order to reduce the overlapped light irradiated to the portion of the track, reduce the overall irradiation intensity, and improve the overall utilization rate of the light, the light emitting elements in the light emitting module 210 corresponding to the portion of the track have a larger installation gap therebetween, and the light generated by the light emitting module 210 can be more irradiated to the plants on the rest of the cultivation layers, so as to reduce the proportion of the redundant light irradiated to the at least part of the plants at the far end 101b and improve the proportion of the effective light irradiated to the at least part of the plants on the rest of the cultivation layers.

Preferably, the mounting gap of each light emitting element in the light emitting module 210 on the side of the second lighting assembly 21b along the axial direction of the shaft body 101 and near the ground end 101a thereof is smaller, and similarly, at least a part of the plants closer to the ground end 101a of the first track 102 is farther from the second lighting assembly 21b, the effective light which can be received by the LED is weak, so that the installation gap of the light-emitting elements corresponding to the position is small, so as to increase the higher light quantum flux generated by the superposition of partial light rays, avoid the overlow composite light received by the plant, increase the light required by the plant to increase the utilization rate of the plant to the light rays, and also avoid the inhibition effect of the overlow light intensity on the growth of the plant, meanwhile, the radiation diffusion based on light increases the amount of overlapped light generated by each light emitting element to reduce the dispersion of light so that more light can be concentrated at the position to provide stronger illumination. Further, the specific installation gap can be obtained by calculating parameters such as a suitable photon flux and a photon flux density according to a specific design structure of the first rail 102 by a formula.

According to a preferred embodiment, as shown in fig. 2 and 5, a plurality of second tracks 103 having different lengths are distributed on the circumferential outer side surface of the shaft body 101 at intervals along the axial direction thereof. Specifically, the second rail 103 is inclined to the ground approximately at a certain angle. Preferably, the inclined state facilitates the liquid to fall down by gravity. Further, the inner side of the second track 103 is configured as a second channel 1030, the first channel 1020 being configured for carrying the first track 102 and for transporting a nutrient solution. The first track 102 and the second track 103 are coaxially arranged. And the plurality of first rails 102 and the plurality of second rails 103 construct a plurality of planting sections P for plant cultivation on each cultivation layer of the first rails 102 in such a manner that their respective channels intersect with each other, as shown in fig. 6. In particular, the planting sections P on adjacent planting layers are arranged offset from each other with a certain gap when viewed from above in the second direction, in order to increase the utilization of the planting gaps in the first and second directions.

According to a preferred embodiment, the lengths of the plurality of second tracks 103, as viewed from above in the second direction, assume successively increasing positions in a direction from the distal end 101b to the proximal end 101b of the shaft 101, as shown in fig. 2 and 5. Specifically, the length of the second track 103 proximate to the distal end 101b of the shaft body 101 is the shortest, and the length of the second track 103 proximate to the proximal end 101b of the shaft body 101 is the longest. Further, the length difference of the second rails 103 in the axial direction of the shaft body 101 is set according to the structure of the first rail 102. Since the curve surrounding radius of the first track 102 in the direction extending along the distal end 101b of the shaft body 101 toward the proximal end 101a thereof or the vertical distance therebetween from the shaft body 101 is in a geometrically and/or equally proportionally increased posture, the second track 103 relatively close to the distal end 101b needs to carry the first track 102 having a smaller or smaller number of curve surrounding radii, while the second track 103 relatively close to the proximal end 101a needs to carry the first track 102 having a larger or smaller number of curve surrounding radii.

According to a preferred embodiment, the first tracks 102 and the second tracks 103 form planting sections P for plant cultivation on the respective cultivation layers of the first track 102 in such a manner that their respective channels intersect each other. Preferably, the gaps between the planting areas P in each cultivation layer of the first track 102 may be the same or different, which mainly depends on the type of plants cultivated in each cultivation layer and enables the limited space to be fully utilized, and while adjusting the number of the first tracks 102, the distance between the first tracks and the layer distance between each cultivation layer, the number of the second tracks 103 and the distance between the second tracks can be adjusted to change the number of the planting areas P and the distance between the second tracks and the layer distance between each cultivation layer, so as to fully utilize the planting space in each cultivation layer of the first track 102 and enable the plants in each cultivation layer to receive more light.

According to a preferred embodiment, the invention can be adapted to known hydroponic and/or aeroponic plant cultivation methods. Preferably, in the case of hydroponics, when plants in a plurality of planting areas P formed by the arrangement of the first rail 102 and the second rail 103 are cultivated, the nutrient solution can flow downwards along the first channel 1020 of the first rail 102 due to gravity and wet the roots of the plants when reaching the corresponding planting areas P, so that the plants in each planting area P can absorb the nutrient supplied by the nutrient solution to promote the growth thereof.

According to a preferred embodiment, as shown in fig. 1 to 6, the shaft body 101 is a plurality of planes perpendicular to the first track 102, which are distributed along the axial direction of the shaft body 101 and formed in a circular, elliptical or spiral shape by the first track 102 rotating around them. Preferably, the inside of the shaft body 101 is configured as a hollow passage 1010 extending in the axial direction thereof. Further, a pipe 1011 for delivering a nutrient solution is disposed in the hollow passage 1010. The outer circumferential surface of the pipe 1011 is formed with a plurality of outlet holes 1012 arranged at intervals along the axial direction thereof, as shown in fig. 7.

According to a preferred embodiment, each lead-out hole 1012 is connected to an end of the second rail 103 extending into the shaft body 101. Preferably, a liquid extraction device of a centrifugal pump or the like may be provided in the pipe 1011 to extract the nutrient solution flowing to the bottom of the pipe 1011 to the top of the pipe 1011 along the extending direction of the pipe 1011, and the nutrient solution can flow into the second channel 1030 of the corresponding second rail 103 through each of the guide holes 1012 and flow downward based on the gravity caused by the inclined state of the second rail 103 when being sucked to each of the guide holes 1012. Further, both ends of the pipe 1011, which are close to the proximal end 101a and the distal end 101b of the shaft body 101, respectively, are connected to both ends of the first rail 102 extending into the shaft body 101, so that the nutrient solution flowing along the first channel 1020 of the first rail 102 can finally flow into the pipe 1011, and can flow into the first channel 1020 of the first rail 102 again when being pumped to the top of the pipe 1011, thereby repeating the above-mentioned nutrient solution irrigation process.

According to a preferred embodiment, the curvature of any point on the second rail 103 in the shape of an arc decreases as the distance from the shaft 101 increases. In other words, the curvature of the second track 103 has a decreasing trend along its extension. Preferably, based on the gravity, the nutrient solution will flow along the extending direction of the second channel 1030, during the flowing process, the plants in the top planting area P of the second track 103 are firstly contacted with the nutrient solution, and then the nutrient solution is firstly contacted with the plants in the planting area P below the second track 103, because the curvature of the second track 103 is continuously reduced, the residence time of the nutrient solution in the top planting area P of the second track 103 is longer, because the larger curvature has a certain temporary effect on the flowing of the nutrient solution, so that the contact time of the nutrient solution with the plants in the top planting area P is longer, the effective absorption of the nutrient substance in the nutrient solution by the corresponding plants is increased, and along with the continuous reduction of the curvature in the extending direction of the second track 103, the flowing speed of the nutrient solution is gradually increased, and the contact time of the nutrient solution with the plants in the bottom planting area P of the second track 103 is gradually reduced, this is to consider that the nutrient solution in the top planting area P of the second track 103 is limited in the nutrient solution retention space provided by the top planting area P, or limited in the suspension effect provided by the curvature characteristics, so that the nutrient solution in the top planting area P continues to flow downward, thereby supplementing the nutrient solution in the bottom planting area P, and meanwhile, to prevent the plants in the bottom planting area P from being burned due to too high concentration of the nutrient solution.

According to a preferred embodiment, a phosphor-coated light emitting plate may also be provided near the plant root system in the planting region P, preferably, for example, above the plant roots, to provide a lightless growing environment to the plant root system, and receive light and be excited to emit light of a certain wavelength while at least a portion of the light emitted by the first and/or

second lighting assemblies

21a, 21b passes through the plant leaves.

According to a preferred embodiment, after the phosphor luminescent material on the light emitting plate is excited and emits light with a certain wavelength and intensity, the light emitted by the light emitting plate can be detected by the optical detection element for determining the growth state or progress of the plant leaves, for example, the amount of light that can be received and/or transmitted by the leaves in different growth states is different, which reflects to a certain extent the growth cycle of the plant, the current growth rate of the plant, and the like. Preferably, the position of the optical detection element is not particularly limited as long as the light receiving and detecting can be completed, and in this embodiment, for example, the optical detection element can be disposed at the bottom of the cultivation layer above the plant to emit light below the cultivation layerThe light emitted from the plate is received and detected. Further, the growth condition of the plant is judged by the difference and change of the emitted light, and other parameters such as temperature, moisture and CO in the growth environment of the plant can be further judged according to the growth condition of the plant₂Concentration, etc. is supplied in sufficient or excessive amounts. Preferably, photosynthesis of the plant is accompanied by CO for at least part of the time, for example when the light intensity is constant₂Increased in concentration and in CO₂When the concentration reaches a threshold value, CO₂The concentration has little effect on photosynthesis, but causes a continuous decrease in respiration, and a decrease in net photosynthetic rate of the plant affects the growth and development of the plant.

According to a preferred embodiment, different types of plants and their corresponding growth cycles, as well as the types of light required by different plants in different growth cycles, the illumination times and their intensities, etc. can be correlated with each other to build a light recipe database suitable for a plant factory, so that suitable growth recipes can be set for different types of plants on the basis of the light recipe database, so that when different plants are grown, only the growth recipes correlated with them need to be called. For example, for lettuce, the irradiation light with the duration of 2h and the intensity of 100% is needed in the seedling raising period; for cauliflower, it requires irradiation light with an intensity of 60% for a period of 2h during the quality-forming period. Preferably, the illumination duration and illumination intensity in different plant growth schemes are customizable, i.e. the light intensity and duration can be combined differently from each other in order to meet the optimal conditions for plant growth. Further, the optical prescription database can keep a continuously updated state according to the change of the data such as the plant species, the environmental parameters and the like, so that the plants planted in the plant factory are correspondingly provided with growth schemes meeting different planting requirements.

According to a preferred embodiment, the first communication means 202 are used to establish a communication link between the management means 201, which are set up outside the plant factory, and the second communication means 203, which are set up inside the plant factory. Preferably, the first communication device 202 includes a wired/wireless form.
