CN111174153A discloses a kind of mobile plant supplementary light device, which includes a supplementary light unit and a guide rail unit. The supplementary light unit includes a mobile bracket, a supplementary light installation frame arranged on the mobile support, and several plants arranged on the supplementary light installation frame. Filling light; the guide rail unit includes a fixed bracket and a guide rail connected with the fixed bracket; the movable bracket is movably connected with the guide rail; the mobile bracket has side legs respectively located on both sides of the guide rail, and the ends of the side legs are rotatably connected with walking wheels, and the walking wheels It abuts against the guide rail; one of the traveling wheels is connected with a driving device.

Plants at various planting points in the planting area can receive light with appropriate proportion, intensity and uniform illumination; for the three-dimensional structure, although it can effectively increase the space utilization rate, when it is irradiated with the corresponding supplementary light equipment , is nothing more than the means of arranging light sources on each planting layer or setting up mobile light supplement equipment that can move in the vertical direction based on a three-dimensional structure, but this also has light irradiation and blind areas of illumination, and the light irradiation it can provide uneven problem. Secondly, when using supplementary light equipment to grow and irradiate plants, the design of the light source often adopts the method of combining light sources with different emission wavelengths or light colors according to a certain gap and independently driven by electricity, but it ignores the In actual irradiation, when light sources with different emission wavelengths are combined for irradiation, based on the distance difference between each planting point and the light source, the actual light that each planting point can receive is different, so a similar equidistant The method of arranging light sources in a different way cannot meet the light requirements of plants in different positions, that is, it cannot make each planting point receive effective and uniform light with appropriate intensity and reasonable proportion.

Preferably, the end of the shaft body 101 close to the ground is defined as the proximal end 101a, and the end far away from the ground is defined as the distal end 101b.

According to a preferred embodiment, as shown in FIG. 1 , the first track 102 is configured as a helical track that extends axially along the shaft body 101 and is formed in a substantially circular spiral manner starting from the axis of the shaft body 101 . Preferably, the shape with spiral diffusion may include regular spirals and/or irregular spirals, as long as the vertical distance between each point on the curve extending in a specified direction and the shaft body 101 presents a gradually increasing or decreasing posture. .

According to a preferred embodiment, the first track 102 extends axially along the shaft body 101 to form a number of cultivation layers with different inter-layer distances. The scope of at least one cultivation layer can be limited to a complete plane formed by the first track 102 around the shaft body 101, a half plane or other options, which mainly depends on the planting requirements of each cultivation layer, because each The plants cultivated in the cultivation layer can be the same or different, and based on the growth forms that different plants may have in different growth cycles, each plant will have at least some differences in appearance and shape, so it is based on the type of plants that actually need to be planted. The purpose of adjusting the layer spacing between the cultivation layers and the limited range of the cultivation layers is to adapt to the growth characteristics and growth performance of different plants, so as to promote their growth and development so that they can show the best growth state. Preferably, based on the design structure of the first track 102, not only can the plants planted on each cultivation layer maintain an excellent growth state, but also make full use of the limited space between each cultivation layer.

According to a preferred embodiment, the first track 102 is configured to take the shaft body 101 as the center of rotation, and extend to the proximal end 101a of the shaft body 101 along the distal end 101b of the shaft body 101 in a manner shaped around the shaft body 101, and the first The radius of the curve of the track 102 extending from the distal end 101b to the proximal end 101a of the shaft 101 or its vertical distance from the shaft 101 increases geometrically and/or proportionally. Optionally, at least a portion of the first track 102 on the side close to the distal end 101 b has a smaller radius around the curve or a shorter vertical distance from the shaft body 101 . And at least part of the first track 102 near the side of the near-ground end 101a has a larger radius around the curve or a longer vertical distance from the shaft body 101, which is considering the distance between the plants at the far-end end 101b The light source is closer, and it receives more or more light than the plants at the bottom. The plants at the nearer end 101a are farther away from the light source, and receive less or weaker light than the plants at the top. Preferably, light-loving plants or plants with a long photoperiod can be planted in at least a part of the orbit relatively close to the far end 101b, or plants with smaller bodies can be planted around a radius based on a smaller curve; Low-light tolerant plants or plants with short photoperiods are planted in at least part of the track of the end 101a, or plants with larger body size are planted around a radius based on a larger curve. Further, the inner side of the first track 102 is configured as a first channel 1020 extending along its surrounding direction and matching the shape of the first track 102, and the first channel 1020 is configured for carrying, cultivating plants and transporting nutrient solution .

According to a preferred implementation manner, as shown in FIG. 3 , several first rails 102 may be provided on the circumferential outer surface of the shaft body 101 . Specifically, the plurality of first rails 102 may be arranged on the circumferential outer surface of the shaft body 101 in a manner of spirally encircling each other in the first direction and/or the second direction based on a certain gap. Optionally, the mutual gaps of several first rails 102 in the first direction and/or the second direction may be the same or different, depending on the type of plants cultivated by the plant cultivation frame 10, in order to adapt to the growth of different plants Form or the demand for illumination, by adjusting the gap between several first rails 102 so that the plants located at each planting point in each cultivation layer on multiple first rails 102 can receive appropriate illumination and adapt to According to its own growth characteristics, the maximum growth is carried out, as shown in Figure 6. Preferably, with the shaft body 101 as the center, in the direction away from the shaft body 101 along the first direction, several first rails 102 are arranged in such a way that their overall volume presents a geometric progression and/or proportionally increases , or at least some of the first rails 102 in the same plane have curve radii that increase geometrically and/or proportionally. And the overall volume of the first track 102 that is closer to the shaft body 101 is smaller than the overall volume of the first track 102 that is farther away from the shaft body 101, that is, when viewed from above in the second direction, it is composed of several first tracks 102 Several cultivated layers are presented in a staggered posture, as shown in Figure 6. Preferably, based on the phototaxis when the plants grow, the plants on the different cultivation layers of the several first tracks 102 that are staggered with each other can be exposed to the light to the greatest extent and receive light with a reasonable proportion and appropriate intensity, so that they can The excellent growth state such as vertical upward growth is maintained to the greatest extent.

According to a preferred embodiment, at least part of the peripheral outer surface of the shaft body 101 is provided with a substantially ring-shaped second lighting assembly 21b. The distal end 101b of the shaft body 101 is provided with a plurality of movable and substantially linear first lighting assemblies 21a. Specifically, the first lighting assembly 21a may be foldable, which is to consider that the first lighting assembly 21a located above the first rail 102 needs to use natural light or sunlight to illuminate the growth of plants without additional supplementary light lighting equipment. A lighting assembly 21a will block at least part of the plants below it, thereby preventing a part of the sunlight from shining on the surface of the covered plants, so that compared with other plants, it will show phenomena such as growth retardation, so it can be controlled manually or based on external drive In this way, the first lighting assembly 21a is folded toward the direction close to the shaft body 101, so as to reduce its blocking of the irradiating light so that several plants on the first track 102 can receive uniform light for normal growth and development. . Or make at least one first lighting assembly 21a close to the shaft body 101 manually or based on an external autonomous driving method, that is, the first lighting assembly 21a and the shaft body 101 are in a state parallel to each other, so as to eliminate the The component 21a hinders the irradiation of part of the light so as to affect the growth and development of plants.

According to a preferred embodiment, the second lighting assembly 21b can take the axis body 101 as the center and emit a roughly ring-shaped light outward along its radial direction to perform supplementary light irradiation on the plants on the spiral first track 102 . Specifically, when the first lighting assembly 21a above the first track 102 is used to illuminate the growth of the plants below it, in addition to the ideal state, some plants will inevitably cause light blocking to each other during the growth process, for example, they are relatively close to each other. The plants on the top will block the light of the plants below; or due to the rotation and/or swinging of the first lighting assembly 21a, when the plants on the first track 102 are illuminated, there will be at least a part of the blind area of light, such as relatively At least part of the track of the first track 102 close to the shaft body 101 may be blocked by the first track 102 at its periphery. Therefore, based on this situation, at least a part of plants cannot use their leaves to receive effective light to perform photosynthesis required for growth and development, so the second lighting assembly 21b can be used to cooperate with the first lighting assembly 21a to illuminate the second lighting assembly from the opposite inner side. Plants on a track 102 are illuminated with supplementary light, that is, when the ideal full coverage of light cannot be satisfied by the first lighting assembly 21a, the plants can be irradiated from multiple angles with the second lighting assembly 21b. Preferably, considering the phototaxis of plant growth, the light intensity of the second lighting assembly 21b and the first lighting assembly 21a may be the same or different from each other, the purpose of which is to enable the plants on each cultivation layer to follow the most excellent growth posture To grow, in addition to making it have good quality, it is also to make full use of the planting space on each first track 102 and its cultivation layer. Further, the ratio of the light intensity of the second lighting assembly 21b to that of the first lighting assembly 21a can be adjusted according to the real-time growth status of the plants on each cultivation layer. Specifically, real-time growth status of plants can be detected by means of camera equipment, for example. For example, when the plants on the first track 102 present a growth posture approaching to the bending of the shaft body 101, the ratio of the light intensity of the first lighting assembly 21a to the second lighting assembly 21b can be appropriately increased, so that the plants can keep as much as possible The posture of vertical growth.

According to a preferred implementation manner, the first lighting assembly 21a can illuminate the growth of the plants on the first track 102 in a state approximately parallel to the ground. Alternatively, the plants on the first track 102 are irradiated for growth in a state parallel to the generatrix of the roughly conical structure formed around the first track 102 , as shown in FIG. 9 . Preferably, the first lighting assembly 21a can provide a generally frustum-shaped and/or conical light coverage area to the first illumination assembly 21a by rotating around the shaft body 101 through a rotating assembly disposed at the distal end 101b of the shaft body 101. Plants on track 102. There is no limitation on the specific structure of the rotating assembly, and a structure commonly used in the prior art that enables the second lighting assembly 21b to rotate around the shaft body 101 can be used. Preferably, compared with the static light source with a larger light coverage area in the prior art, the first lighting assembly 21a in the embodiment of the present invention is configured as a dynamically movable linear light source, that is, through the first lighting assembly 21a The emitted light is more concentrated to increase the corresponding irradiation intensity, and the dynamic light source greatly reduces the corresponding blind area of irradiation, so that more leaves can receive the light, and at the same time, the blocking effect of the cilia on the surface of the leaf is also greatly weakened, thus Other parts of the leaves, such as the light-receiving parts on the back side of the leaves, can also receive more light irradiation, which is more conducive to the uniform growth of plants.

According to a preferred embodiment, when the first lighting assembly 21a illuminates the plants below it, its specific posture is completed manually or by external autonomous drive, and for external autonomous drive, its The adjustment of the specific posture is based on the monitoring of the plant growth state or the plant growth environment by the external equipment. Further, the monitoring of the plant growth state can be accomplished by means of detecting the plant leaf area and plant growth height commonly used in the prior art, such as camera equipment; the monitoring of the plant growth environment can be performed by using sensors to detect the plant growth area It can be done by means of parameters such as air humidity, temperature, light intensity, CO ₂ or O ₂ concentration.

Preferably, after the camera equipment captures the image of the plant growth state on the cultivation layer at the upper end of the first track 102, 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 When the plant leaf area reaches the preset growth threshold, the external control device or the central control device can drive the first lighting assembly 21a to expand in a direction away from the shaft body 101, and at this time the plants on the lower cultivation layer may not meet the corresponding requirements. Since the distance between the tail end of the first lighting assembly 21a and the cultivation layer at the lower end increases, the light intensity will decrease, and the light on the side of the first lighting assembly 21a away from the shaft body 101 can be enhanced by external driving. The luminous intensity of the light emitting elements and the luminous intensity of the light emitting elements in other sections of the first lighting assembly 21a are properly adjusted to adapt to the change of the light intensity caused by the change of the light distance.

Or, after the camera equipment collects the image of the plant growth state on at least part of the cultivation layer of the first track 102, the external control device or the central control device analyzes the image and compares it with the standard data in the database, when for example the plant leaf area When the preset growth threshold is reached, the external control device or the central control device can drive the first lighting assembly 21a to close and/or expand in a direction approaching and/or away from the shaft body 101, and drive the first lighting assembly 21a by rotating the assembly. For plants in other areas that do not meet the corresponding growth threshold, the luminous intensity of the light-emitting elements in different sections of the first lighting assembly 21a can be adjusted based on external driving to meet the requirements of the plants in the corresponding area. Grow light needs.

Preferably, when the sensor detects the _CO2 concentration, _O2 concentration or its concentration ratio in at least a part of the first track 102, the external control device or the central control device analyzes the value and compares it with the standard data, when the CO ₂ concentration, _O2 concentration or its concentration ratio reaches a preset threshold, for example, when the _CO2 concentration is lower than a certain threshold and the _O2 concentration is higher than a certain threshold or its concentration ratio is higher than a certain threshold, it can be considered that the If the net photosynthesis of the plant is strong, the first lighting assembly 21a can be adjusted based on the driving of the external control device or the central control device to draw and/or expand, and the rotation of the first lighting assembly 21a can be driven by the rotating assembly to reduce the corresponding Lighting of preset threshold areas, and/or enhancing lighting of areas not meeting preset thresholds.

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

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

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 driven independently to provide the plants on the first track 102 with the light required to meet their different growth requirements. For example, a blue LED light source with an emission wavelength of 400nm to 450nm can be used to promote the growth of plant leaves and stems, a red LED light source with an emission wavelength of 620nm to 760nm can be used to promote flowering and fruiting of plants, and a green LED light source with an emission wavelength of 492nm to 577nm Can be used to delay leaf senescence.

Preferably, the first light-emitting unit 210a, the second light-emitting unit 210b, and the third light-emitting unit 210c can be driven simultaneously to form composite light similar to natural light, and the intensity ratio of each light-emitting unit can be changed to change the composite light. Light quality can change the irradiation effect on plants so that it can show the best growth state based on the excellent irradiation environment. Specifically, the proportion of red light can be appropriately increased to reduce the proportion of blue light. This is not only because excessive blue light may delay or inhibit plant growth, hinder its synthesis of carbohydrates, etc., but also because blue light has a certain effect on the human eye. harm. For example, for some leafy vegetables, there are certain requirements for the ratio of red and blue light at the seedling stage. In order to increase the seedling quality of the corresponding leafy vegetables at the seedling stage and prevent them from growing excessively, the ratio of red and blue light can be appropriately lowered.

According to a preferred embodiment, several first rails 102 are configured to take the shaft body 101 as the center of rotation, extending from the distal end 101b of the shaft body 101 to its proximal end 101a in a manner shaped around the shaft body 101, and the first The radius of a track 102 along the direction extending from the distal end 101b of the shaft body 101 to the proximal end 101a of the curve around the radius or the vertical distance between the shaft body 101 presents a gesture of geometric progression and/or proportional increase Therefore, in order to adapt to the lighting requirements based on the design structure of the first track 102, the light emitting module 210 formed by a combination of several light emitting units that can be independently driven and have different emission wavelengths or light colors in the first lighting assembly 21a is configured. In other words, when viewed along the substantially linear arrangement direction of the first lighting components 21a, the installation gaps between 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 in equal proportions. increased or decreased, as shown in Figure 8. That is, the installation 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 on the side closer to the shaft body 101 is larger than that of the light-emitting module 210 on the side farther from the shaft body 101. The installation gaps between the first light-emitting unit 210a, the second light-emitting unit 210b and the third light-emitting unit 210c inside are determined. Preferably, the specific installation gap can be obtained according to the specific design structure of the first track 102 and by calculating parameters such as suitable light quantum flux and light quantum flux density through formulas.

According to a preferred embodiment, the installation gaps between the light emitting elements in each light emitting module 210 are different from each other because the light quality combination, ratio and intensity of the first lighting assembly 21a are located on the first track 102 below it. The effect of irradiation on the plants. Specifically, when the light-emitting elements with different emission wavelengths are arranged alternately and emit light simultaneously, at least a part of the light generated by them is coincident. , so the light rays in the overlapping parts of the area have a high photon flux, while the light rays in other non-overlapping parts of the region have a lower photon flux. is a spiral multilayer structure corresponding to the first track 102 in the present invention.

According to a preferred embodiment, when the first lighting assembly 21a is irradiating the plants below it on several cultivation layers of the first track 102 based on its own horizontal posture, if the same installation gap and light intensity are used to illuminate the plants Illumination, based on the different light distances between the plants on each cultivation layer and the first lighting assembly 21a along the second direction, the effective illumination available to the plants on each cultivation layer is different, especially, especially The light received by the plants on the cultivation layer at the bottom of the first track 102 is more limited. Further, since the radius of the curve of the first track 102 in the present invention extends from the distal end 101b of the shaft body 101 to the proximal end 101a of the shaft body 101, or the vertical distance between it and the shaft body 101 is geometrically Therefore, in order to adapt to the change of the surrounding radius of the first track 102 to meet the uniform illumination of the plants on each cultivation layer, the installation gaps between the light emitting elements in the first lighting assembly 21a As the first track 102 extends along the direction from the distal end 101b of the shaft body 101 to its proximal end 101a, the radius of the curve that presents a geometric progression and/or proportionally increases gradually decreases, that is, At least some of the plants closer to the far end 101b of the first rail 102 are closer to the first lighting assembly 21a, and the effective light they can receive is stronger, so the installation gap between the light emitting elements corresponding to this position is relatively large. , in order to reduce the higher photon flux produced by partial light overlap, and avoid the plants receiving too strong light. In addition to preventing the redundant light at this place from causing waste and making it impossible to be effectively used, it can also prevent too strong At the same time, based on the radiation diffusion of light, the coincident light generated by each light-emitting element is reduced, and the area covered by its light is expanded.

According to a preferred embodiment, the installation gap of each light-emitting element in the light-emitting module 210 on the side of the first lighting assembly 21a close to the shaft body 101 is relatively large, so that the light-emitting elements of the first lighting assembly 21a overlap and illuminate at least the far end 101b of the first rail 102. The light intensity of some plants is reduced, and the light generated by the light-emitting element at this place can also irradiate more plants on the other cultivation layers, for example, the plants on the cultivation layer relatively far away from the remote end 101b, so as to reducing the proportion of redundant light irradiated to at least some of the plants at the remote end 101b and increasing the proportion of effective light irradiated to at least some of the plants on the rest of the cultivation layer. On the other hand, the light-emitting elements in the light-emitting module 210 at the tail end of the first lighting assembly 21a away from the shaft body 101 have the smallest installation gap. The plant is far away from the first lighting assembly 21a, and the effective light it can receive is relatively weak, so the installation gap between the light emitting elements corresponding to this place is relatively small, so as to increase the high light quantum flux generated by the overlapping of some light rays. In order to prevent the complex light received by the plants at this place from being too low, increase the light required by the plants at this place to increase the utilization rate of light, and also avoid the inhibition of plant growth caused by too low light intensity. At the same time, based on light Radiation diffusion increases the coincident light generated by each light-emitting element, so as to reduce the dispersion of the light so that more light can be concentrated there to provide stronger illumination.

According to a preferred embodiment, the installation gap of each light-emitting element in the light-emitting module 210 on the side of the first lighting assembly 21a close to the shaft body 101 is relatively large, so that the light-emitting elements of the first lighting assembly 21a overlap and illuminate at least the far end 101b of the first rail 102. The light intensity of some plants is reduced, and the light generated by the light-emitting element at this place can also irradiate more plants on the other cultivation layers, for example, the plants on the cultivation layer relatively far away from the remote end 101b, so as to reducing the proportion of redundant light irradiated to at least some of the plants at the remote end 101b and increasing the proportion of effective light irradiated to at least some of the plants on the rest of the cultivation layer. Preferably, based on the arrangement of the installation gaps of the light-emitting elements in the first lighting assembly 21a, when the plants on the first track 102 are irradiated by adjusting the posture of the first lighting assembly 21a, it can be based on The distance between the first lighting assembly 21a and the plants on each cultivation layer is adapted to the light intensity caused by the change of the light distance by adjusting the ratio and intensity of the light sources of the light emitting elements in different sections of the first lighting assembly 21a The change. For example, when the light-emitting module 210 at the tail end of the first lighting assembly 21a is close to the plants on the cultivation layer at the bottom of the first track 102, the luminous intensity of each light-emitting element in the light-emitting module 210 in this area can be correspondingly reduced to provide a suitable light intensity, or Based on the growth characteristics of the plants on the bottom cultivation layer, the ratio of each light emitting element is properly adjusted to provide a suitable ratio of light sources.

According to a preferred embodiment, the arrangement of the installation gaps between the light emitting units in the light emitting modules 210 of the second lighting assembly 21b is the same as that of the first lighting assembly 21a. Specifically, in the direction extending from the distal end 101b to the proximal end 101a of the shaft body 101, the installation gaps between the light emitting units in the light emitting modules 210 of the second lighting assembly 21b decrease sequentially. From this point of view, the second lighting assembly 21b has a larger installation gap of the light emitting elements in the light emitting module 210 on the axial direction of the shaft body 101 and near the side of the distal end 101b, while the second lighting assembly 21b The installation gap of each light emitting element in the light emitting module 210 on the axial direction of the body 101 and on the side close to the near end 101a thereof is relatively small.

Preferably, the part of the first track 102 that is close to the side of the distal end 101b of the shaft body 101 has a smaller radius around it or its distance from the shaft body 101 is closer, then the effective illumination that this part of the track can receive is compared to The lower part of the track is more or stronger. Therefore, in order to reduce the overlapping light irradiated to this part of the track, reduce the overall illumination intensity and improve the comprehensive utilization of light, each light-emitting element in the light-emitting module 210 corresponding to this part of the track There is a large installation gap between each other, and at the same time, the light generated by the light emitting module 210 can be more irradiated to the plants on the other cultivation layers, so as to reduce the redundancy of irradiating at least some plants on the remote end 101b. The ratio of the remaining light and the ratio of increasing the effective light irradiated to at least part of the plants on the rest of the cultivation layer.

Preferably, the installation gap of each light emitting element in the light emitting module 210 of the second lighting assembly 21b on the axial direction of the shaft body 101 and close to the side near the ground end 101a is relatively small. 102 At least some of the plants near the ground end 101a are far away from the second lighting assembly 21b, and the effective light they can receive is weak, so the installation gaps between the light emitting elements corresponding to this place are small to increase the amount of light caused by part of the light. The higher light quantum flux generated by the coincidence can avoid the low composite light received by the plants at this place, increase the light required by the plants at this place to increase the utilization rate of light, and also avoid the damage caused by the low light intensity on plant growth. At the same time, based on the radiation diffusion of light, the coincident light generated by each light-emitting element increases to reduce the dispersion of the light so that more light can be concentrated there to provide stronger illumination. Further, the specific installation gap can be obtained according to the specific design structure of the first track 102 and by calculating parameters such as suitable photon flux and photon flux density through formulas.

According to a preferred embodiment, as shown in FIG. 2 and FIG. 5 , a plurality of second rails 103 with different lengths are arranged at intervals along the axial direction of the shaft body 101 on the outer peripheral surface of the shaft body 101 . Specifically, the second track 103 is roughly inclined to the ground, forming a certain angle with the ground. Preferably, the tilted state is favorable for the liquid to fall down with the help of gravity. Further, the inner side of the second track 103 is configured as a second channel 1030, and the first channel 1020 is configured to carry the first track 102 and transport the nutrient solution.

According to a preferred embodiment, when viewed from above along the second direction, the lengths of several second rails 103 present a posture that increases sequentially along the direction of arrangement from the distal end 101b to the proximal end 101b of the shaft body 101 , as shown in Figure 2 and Figure 5. Specifically, the length of the second rail 103 near the distal end 101b of the shaft body 101 is the shortest, and the length of the second rail 103 near the proximal end 101b of the shaft body 101 is the longest. Further, the length difference of each second track 103 in the axial direction of the shaft body 101 is set according to the structure of the first track 102 . Because the radius of the curve of the first rail 102 in the direction extending from the distal end 101b of the shaft body 101 to its near-earth end 101a or the vertical distance between it and the shaft body 101 presents a geometric progression and/or proportional increase Large posture, so the second track 103 relatively closer to the distal end 101b needs to carry a curve around the first track 102 with a smaller radius or fewer numbers, while the second track 103 relatively closer to the proximal end 101a needs to bear a curve Around the first track 102 with a larger radius or a smaller number.

Preferably, the gaps between several planting regions P in each cultivation layer of the first rail 102 may be the same or different, which mainly depends on the types of plants cultivated in each cultivation layer and the limited space can be fully utilized While adjusting the number of the first rails 102, the distance between them and the layer distance of each cultivation layer, the number of the second rails 103 and the distance between them can be adjusted to change the number of planting regions P and the distance between them, so that The planting space in each cultivation layer of the first track 102 is fully utilized, and the plants in each cultivation layer can receive more light.

According to a preferred embodiment, the present invention can be adapted to the known methods of growing plants in hydroponics and/or aeroponics. Preferably, taking the hydroponics method as an example, when cultivating plants in several planting areas P formed by the configuration of the first track 102 and the second track 103, the nutrient solution can flow along the first track 102 based on gravity. The first channel 1020 flows downward and soaks the root system of the plants when it reaches the corresponding planting area P, so that the plants in each planting area P can absorb the nutrients supplied by the nutrient solution to promote their growth.

According to a preferred embodiment, as shown in Figures 1-6, the shaft body 101 is a number of circular, circular, and vertical shafts distributed along the axis of the shaft body 101 perpendicular to the first rail 102 and formed by the rotation of the first rail 102 around it.

According to a preferred implementation manner, each outlet hole 1012 is connected with one end of the second rail 103 extending into the shaft body 101 . Preferably, a liquid pumping device such as a centrifugal pump may be provided in the pipeline 1011 to draw the nutrient solution flowing to the bottom of the pipeline 1011 to the top of the tube body 1011 along the extending direction of the tube body 1011, and the nutrient solution is sucked When arriving at each outlet hole 1012 , it can flow into the second channel 1030 of the corresponding second rail 103 through each outlet hole 1012 , and flow downward based on the gravity effect caused by the inclined state of the second rail 103 . Further, the two ends of the pipeline 1011 which are close to the proximal end 101a and the distal end 101b of the shaft body 101 are connected to the two ends of the first track 102 extending into the shaft body 101, so that the second end along the first track 102 The nutrient solution flowing in a channel 1020 can finally flow into the pipe 1011, and when it is pumped to the top of the pipe 1011, it can flow into the first channel 1020 of the first rail 102 again, thereby repeating the above-mentioned nutrient solution irrigation process.

According to a preferred embodiment, the curvature of any point on the arc-shaped second track 103 decreases continuously in view of the increase of the distance between it and the shaft body 101 . In other words, the curvature of the second track 103 shows a decreasing trend along its extending direction. Preferably, based on the action of gravity, the nutrient solution will flow along the extension direction of the second channel 1030. During the flow, the plants located in the planting area P at the top of the second track 103 will first contact the nutrient solution, and then the nutrient solution will The plants in the planting area P below the second track 103 are first in contact with the nutrient solution, and since the curvature of the second track 103 is constantly decreasing, the residence time of the nutrient solution in the planting area P at the top of the second track 103 is Longer, because the larger curvature has a certain suspending effect on the flow of the nutrient solution, so that it can be in contact with the plants in the top planting part area P for a longer time, thereby increasing the corresponding plants. Effectiveness of nutrients in the nutrient solution absorption, and along with the continuous reduction of the curvature on the extension direction of the second track 103, the flow rate of the nutrient solution is gradually accelerated, and the contact time with the plants in the planting area P at the bottom of the second track 103 is gradually reduced, which is Considering that part of the nutrient solution in the planting area P at the top of the second track 103 will be limited due to the limited nutrient solution retention space that the planting area P can provide, or the limited suspending effect based on the curvature characteristics, it will be located in the top planting area. Part of the nutrient solution in the P will continue to flow downward to supplement the lack of nutrient solution in the bottom planting area P. At the same time, it is also to prevent the burning of the plants in the bottom planting area P caused by the excessive concentration of the nutrient solution. Phenomenon.

Further, the plant growth status can be judged by the difference and change of emitted light, and it can be further judged whether other parameters in the plant growth environment, such as temperature, moisture, _CO2 concentration, etc., are supplied adequately or excessively according to the plant growth status. Preferably, for example, when the light intensity is constant, the photosynthesis of plants is enhanced with the increase of _CO2 concentration at least part of the time, and when the _CO2 concentration reaches a threshold value, the _CO2 concentration has little influence on photosynthesis , but the respiration will continue to weaken, and the net photosynthetic rate of the plant will decrease, which will affect the growth and development of the plant.
