Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, and in particular to an aeroponic system and its aeroponic factory. Background Technology

[0002] Aeroponics, also known as mist culture or aeroponics, is the soilless cultivation technology that best solves the root water-air contradiction among all soilless cultivation technologies. It is easy to automate and carry out three-dimensional cultivation, which can improve the utilization rate of plant factories or greenhouse space.

[0003] Hydroponics can be divided into two types based on whether the plant roots are partially submerged in the nutrient solution layer: hydroponics and semi-hydroponics. Hydroponics refers to a soilless cultivation technique in which the roots grow entirely in the atomized nutrient solution environment; while semi-hydroponics refers to a soilless cultivation technique in which some roots are submerged in the nutrient solution layer at the bottom of the planting trough, while the other part of the roots grows in the atomized nutrient solution environment.

[0004] The advantages of aeroponics technology are: it can solve the problem of oxygen supply to the roots, and there will be almost no poor growth due to root hypoxia; it has high nutrient and water utilization rate, and the nutrient supply is fast and effective; it can make full use of the space in greenhouses or plant factories, increase the planting quantity and yield per unit area, and its space utilization rate is 2 to 3 times higher than that of traditional planar cultivation, and it is also easy to automate cultivation management.

[0005] Existing aeroponic growing beds are often configured as vertical structures to fully utilize vertical space, or the aeroponic growing bed and nutrient supply system are combined with a moving structure to ensure the uniformity and efficiency of aerosol application to the plant roots. The moving structure can be configured as a reciprocating or circulating structure, thereby achieving uniformity of light, aerosol, and other nutrient conditions received by the plants based on the relative reciprocating or circulating motion between the aeroponic growing bed and the nutrient supply system.

[0006] For example, patent CN103563679B discloses an automated seedling bed. This invention uses "W"-shaped seedling trays arranged in a chain to ensure and vary light exposure, resulting in a uniform light-receiving area without mutual shading, thus providing a uniform growth environment for the seedlings. However, the chain-loop structure of this invention cannot effectively divide the planting space into functional zones to accommodate targeted nutrient or intervention equipment. Furthermore, the aerosol nozzles in this design are located at the top of the seedbed, with the aerosol outlets being far from the seedlings receiving the aerosol. This makes the aerosol easily dispersed throughout the cultivation space due to inertia and gravity, potentially obstructing light exposure and making it difficult to ensure the targeted application of the aerosol and the economic efficiency of the aerosol cultivation process.

[0007] Patent CN115777517A discloses an automated aeroponic planting rack with a conveyor belt structure. This solution arranges the mist nozzles close to the plant roots, but the mist is still diffused throughout the cultivation space and cannot be concentrated and effectively applied to the plant roots. In particular, it cannot overcome the problem of the outer part of the plant roots blocking the interior and thus preventing the problem of external moisture and internal dryness.

[0008] Based on the above, existing planting equipment using aeroponic technology cannot effectively meet the requirements of concentrated aeroponic action range, accurate aeroponic action parameters, and uniform aeroponic action in aeroponic culture. In particular, when the outer part of the plant root system blocks the internal root system, or when the plant root system is stuck together, making it difficult for the aeroponic system to penetrate the interior, the aeroponic system mainly contacts the outside of the plant root system and has difficulty entering the interior of the root system. Or, when crop cultivation requires the use of a culture medium layer, so that part or all of the plant root system is not directly exposed to the culture space, the aeroponic system contacts the surface of the culture medium layer and has difficulty entering the interior of the culture medium layer to effectively wet the plant root system. Some roots protruding from the culture medium layer will further block the path of the aeroponic system to move towards the culture medium layer.

[0009] In addition, a large coverage area of ​​the aerosol nozzle or aerosol nozzle placed far away from the plant roots will cause the aerosol to diffuse. The process of the aerosol moving from the aerosol nozzle to the plant will also be affected by gravity, spray direction and airflow interference, resulting in uneven distribution of aerosol effect, thus causing uneven distribution of aerosol nutrients and affecting the uniformity of plant growth rate.

[0010] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventors studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0011] To address at least some of the shortcomings of the prior art, this application provides an aeroponic system. The aeroponic system includes a conveying module for driving plants to move along a set path and an aeroponic module for misting the plants. The conveying module is connected to a planting unit for carrying the plants via a moving track arranged along the set path, so that the planting unit for carrying the plants moves relative to the aeroponic module in at least a portion of the set path. The aeroponic module includes at least a number of functional units for intervening in the plants and at least a number of atomizing units for misting the plants under the intervention of the functional units.

[0012] To address the problem that existing aeroponic systems lack effective functional zoning of the cultured workpiece, making it difficult to ensure the targeted and uniform effect of diffused mist on the plant roots and the effectiveness of parameter control, the aeroponic system of this application divides the cultivation space into several functional zones according to functional requirements. The functional zones are set according to the relative positional relationship between the movement path of the motion module carrying the plant and the associated equipment to meet the corresponding functional requirements. The associated equipment may include lighting equipment, aeroponic equipment, and other intervention equipment. The corresponding functional requirements include light exposure, misting, and intervention operations such as planting and harvesting.

[0013] For example, in light-based cultivation spaces, the movement paths of lighting equipment and conveyor belts can be designed to fully utilize vertical space and the range of light irradiation. Specifically, for aeroponic cultivation, it is necessary to ensure the targeted and economical effects of the aeroponic system. Targetedness means that the aeroponic mist can effectively penetrate the plant's root system to prevent external moisture absorption while internal dryness occurs. Economic efficiency means concentrating the aeroponic mist's effect on the plant rather than allowing it to diffuse, thereby conserving nutrient solution and enhancing the effectiveness of aeroponic cultivation within a defined space.

[0014] The targeted and economical nature of the aforementioned aerosol effect is achieved through several functional units that intervene in the plants, and at least several atomizing units for aerosolizing the plants under the intervention of these functional units. For example, aerosol culture is implemented to intervene and adjust the plant root system, and the range of action of the aerosol on the plant roots and leaf area is limited. While ensuring the relative independence of the aerosol effect, the above setup overcomes defects such as external obstruction and root adhesion by using a conveyor module to carry plant movement in conjunction with the intervention settings and parameter adjustments implemented by the aerosol module. This allows the aerosol to penetrate the plant root system and achieve full contact, thereby improving the targeted and economical nature of aerosol culture in the three-dimensional aerosol farm of this application.

[0015] Preferably, the intervention performed by several functional units on the plant includes at least altering the root distribution and / or limiting the aerosol application range. Altering the root distribution is achieved by manipulating and organizing the plant roots through relative movement between the plant and the functional units. Limiting the aerosol application range is achieved by changing the cross-sectional size of the aerosol application channel along the direction of plant movement. The aeroponic module selectively invokes several functional units and several atomization units, and adjusts one or more of the aerosol application parameters of the corresponding atomization units to apply aerosols to plants at different cultivation stages.

[0016] Based on the aforementioned functional zoning and dynamic cultivation arrangement, this application's aeroponic system, to enhance the applicability of aerosolization to different cultivation stages of plants, includes several functional units that intervene in the plants, as well as atomizing units that cooperate with these functional units to perform aerosolization. The intervention of the functional units in the plants includes intervention on the plant itself and changes in the relative state between the plant and the equipment. For example, intervention on the plant itself includes combing and manipulating the plant's root system to obtain a better aerosolization angle and a larger aerosolization area. Changes in the relative state between the plant and the equipment include altering the flow path for the plant to receive the aerosol, such as limiting the size and direction of the flow path to increase the aerosol concentration and aerosolization efficiency. Furthermore, due to the dynamic growth of the plant's root system, the atomizing units can form aerosols with different directions of action, such as from bottom to top, sideways, and from top to bottom, allowing the combined action of the atomizing units to provide uniform and effective aerosolization to the dynamically cultivated plants.

[0017] Preferably, the aeroponic module includes a first functional unit for combing and manipulating the plant roots and a first atomizing unit for atomized cultivation in conjunction with the first functional unit. The atomized cultivation by the first atomizing unit, in conjunction with the first functional unit, involves a combined spraying of mist and / or jets generated by the first atomizing unit onto the plant roots that have been parted by the first functional unit. The first functional unit includes a horizontal bar for combing and manipulating the plant roots, the height of which can be adjusted by several adjusting rods. The first atomizing unit includes at least a first nozzle and a second nozzle that emit mist or jets from two angles for combined spraying. Several first nozzles and several second nozzles are arranged laterally and positioned on either side of the horizontal bar along its longitudinal projection axis.

[0018] The above setup effectively overcomes the defects of excessive root density or entanglement leading to external dampness and internal dryness, as well as insufficient saturation. The atomization effect includes aerosol flow and jets. Aerosol flow refers to the mist-like flow formed by the aggregation of small droplets, while jets refer to the fluid formed by large droplets or continuous liquid. This allows the atomization module to utilize auxiliary structures to solve the problems of root entanglement and external dampness with internal dryness. The first atomization unit can fully utilize the opening space created by the horizontal bar moving the plant roots through aerosol flow or jets in several directions. This allows the aerosol flow or jets to effectively enter the plant root system, and the aerosol flow or jets acting on both sides of the horizontal bar can act on both sides of the same batch of plant roots, thus achieving uniform atomization.

[0019] Preferably, the first functional unit has a baffle plate on one vertical side of the crossbar to expand the range of action of the mist or jet. The mist or jet acting on the baffle plate can form a mist or jet with an expanded range of action by utilizing the reflection effect of the baffle plate and act on the plant roots on both sides of the longitudinal direction of the crossbar. The crossbar of the first functional unit is provided with a comb structure, wherein the crossbar has a number of ridges that protrude radially from the surface of the crossbar on its circumferential surface, and the height of the ridges protruding from the surface of the crossbar gradually changes along the axial direction. The ridges are arranged at intervals along the transverse direction of the crossbar, so that the ridges can be placed between adjacent roots and use the relative movement of the roots to comb through the knotted positions.

[0020] The baffle increases the aerosol application area as the crossbar separates the plant roots. Roots of the same batch of plants sequentially receive aerosol or jet streams reflected by the baffle on both sides of the crossbar, thus improving the uniformity of aerosol application inside and outside the plant roots through the combined action of the first auxiliary unit and the first spraying unit. The comb-like structure of the crossbar effectively solves the problem of the crossbar failing to effectively separate plant roots due to root entanglement. The crossbar's combing action also clears weak and residual roots from within the plant root system, ensuring sufficient growth space for new and healthy roots. This combing process also ensures appropriate root spacing, effectively promoting healthy root development and improving the efficiency of aerosol application.

[0021] Preferably, the aeroponic module includes a second functional unit for defining the range of the aerosol or jet flow channel and a second atomizing unit for aerosol cultivation in conjunction with the second functional unit. The second atomizing unit performs aerosol cultivation in conjunction with the second functional unit by combining aerosol and / or jet streams generated at several locations to spray the flow channel defined by the second functional unit. The second functional unit includes a longitudinally extending and inclined guide plate, which allows the aeroponic module to form a flow channel whose range of action for the aerosol and / or jet stream gradually decreases in the opposite direction to the movement direction of the moving track. The second atomizing unit includes several nozzles arranged at least at the ends and middle of the flow channel, such that the aerosol and / or jet streams generated by the nozzles move at least in the opposite direction to the movement direction of the moving track of the conveyor module.

[0022] The second functional unit and the second atomizing unit can effectively supplement the aerosol effect of the first functional unit and the first atomizing unit. The first auxiliary unit and the first spraying unit can effectively wet the plant roots protruding from the support layer through the bottom-up aerosol flow or jet. However, for the plant roots that have not yet protruded from the support layer or for the plant roots located in the customized layer, the bottom-up aerosol flow or jet can only contact the surface of the customized layer and cannot effectively penetrate into the customized layer. In addition, the action time of the first auxiliary unit and the first spraying unit is limited, making it difficult to achieve a good continuous penetration effect. The second functional unit and the second atomizing unit use inclined guide plates to form a flow channel with a flow range that gradually narrows in the opposite direction to the movement direction of the conveyor belt. This allows the flow channel to overcome the decrease in aerosol concentration caused by the aerosol flow acting on the plant or equipment and maintain the aerosol at a high concentration level. Thus, the continuous and high concentration of the aerosol action enhances the aerosol cultivation effect and can achieve full coverage of the aerosol action on all directions and positions of the plant.

[0023] Preferably, the aeroponic module is provided with a third atomizing unit for atomizing the planting unit carrying the plant from top to bottom. As the planting unit carrying the plant passes through the third atomizing unit along the moving track, the third atomizing unit generates a mist flow and / or jet stream on the plant through a plurality of nozzles arranged laterally at intervals. The planting unit is provided with a planting layer that provides positioning for crop seeds and crop plants using a loose and porous structure, and at least a support layer for supporting the planting layer. The planting layer is provided with a plurality of partition grooves arranged laterally and / or longitudinally at intervals, such that the plurality of partition grooves arranged laterally at intervals are aligned with a plurality of nozzles of the third atomizing unit.

[0024] In conjunction with the top-down aerosol effect of the first atomizing unit and the side aerosol effect of the second atomizing unit, the third atomizing unit can form a top-down aerosol effect to achieve phased, fully enclosed aerosol cultivation of the plants by the aeroculture module. Specifically, the first atomizing unit primarily acts on the plant roots through bottom-up aerosol spray. The second atomizing unit utilizes lateral aerosol spray to act on the plant roots and leaf area. Some aerosol spray can condense in the leaf area and act on the roots located inside the planting layer from top to bottom. This is especially effective when the bottom-up aerosol spray from the first atomizing unit cannot overcome gravity and structural obstruction to effectively act on the plant roots located inside the planting layer. The third atomizing unit enhances the aerosol spray effects of the first and second atomizing units, particularly for roots located within the planting layer or those that have not yet developed to protrude from the planting layer. The top-down aerosol spray can retain the aerosol spray and condensed nutrient solution on the upper surface of the planting layer and gradually penetrate into the planting layer, flowing along the roots to the roots protruding from the planting layer. This allows the third atomizing unit to simultaneously enhance the aerosol spray effects of the first and second atomizing units, ensuring that the plant receives sufficient aerosol spray from the atomizing module.

[0025] This application also provides an aeroponic factory based on an aeroponic system. The aeroponic factory includes an intelligent module for controlling the aeroponic system to perform aeroponic cultivation. The aeroponic system includes at least a conveyor module for carrying and moving the plants and an aeroponic module for applying aerosols to the plants. The intelligent module is equipped with at least a motion unit for controlling the conveyor module and at least a nutrient unit for controlling the aeroponic module, enabling the motion unit and nutrient unit of the intelligent module to adjust the motion parameters of the conveyor module and the aerosol application parameters of the aeroponic module according to a preset plan and aeroponic cultivation process information. Further, the nutrient unit of the intelligent module adjusts the aerosol application parameters of the aeroponic module by selectively calling several functional units and several atomization units and obtaining the relative positional relationship between the functional units and the conveyor module, as well as the motion parameters of the conveyor module, to adjust one or more of the aerosol application parameters of the corresponding atomization unit.

Detailed Implementation

[0032] Any orientation specified in this application is provided for the convenience of the reader only and does not constitute a limitation on this application. In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] This application provides an aeroponic system and its aeroponic factory, particularly a continuous or intermittent aeroponic system and its aeroponic factory, especially an automated aeroponic system and its aeroponic factory, and further specifically, an aeroponic system and an aeroponic factory based on the aeroponic system. This application establishes an aeroponic system through aeroponic technology and a moving structure, enabling the aeroponic system of this application to serve as a sub-module for building an aeroponic factory, and can be used for the efficient and automated cultivation of crops such as forage, vegetables, and flowers.

[0035] Example 1

[0036] like Figure 2 As shown, the aeroponic system of this application includes a cultivation module 100 for forming a planting space, a conveying module 200 for carrying plants for movement, and an aeroponic module 300 for aeroponic cultivation of plants. The cultivation module 100 forms a plant arrangement and cultivation space through a frame structure. The conveying module 200 arranges a moving structure within the frame structure of the cultivation module 100, so that the moving structure can carry the plants for cyclical or reciprocating movement. The aeroponic module 300 achieves a uniform aeroponic effect by obtaining changes in the spray angle and position of the plants through the conveying module 200.

[0037] To facilitate the description of the structure and orientation of the aeroponic system of this application, the length direction of the plant movement facade is defined as longitudinal, the width direction as vertical, and the direction perpendicular to both longitudinal and vertical as transverse. The plant movement facade refers to the spatial plane formed by the cyclical or reciprocating movement of the plants. In this application, longitudinal and transverse directions are parallel to the horizontal farm plane, vertical is the height direction perpendicular to the farm plane, and the plant movement facade is a vertical plane perpendicular to the farm plane.

[0038] like Figure 2As shown, the cultivation module 100 includes a main frame 101. The main frame 101 forms a frame structure that surrounds and / or supports the conveying module 200 and the aeroponic module 300 through several longitudinal, vertical, and transverse beams. The main frame 101 of the cultivation module 100 utilizes several sealing plates 106 to form physical partitions that at least cover certain areas. Specifically, the cultivation module 100 includes a frame-structured main frame 101, which consists of several vertical beams supported on the ground and extending vertically, longitudinal beams connected to the vertical beams and parallel to the plant movement facade, and transverse beams connected to the longitudinal beams and extending laterally. This frame structure forms or divides the main frame 101 into structural spaces capable of accommodating planting equipment, atomizing equipment, and other equipment. For example, the vertical part of the cultivation module 100 may be a space for arranging lighting equipment, and the vertical part of the cultivation module 100 may be a space for arranging atomizing equipment. The lighting equipment and atomizing equipment can also be arranged on the transverse sides of the cultivation module 100. The cultivation module 100 forms a planting space for arranging plants via a main frame 101. Several planting units 102 are arranged laterally within the planting space. Each planting unit 102 has a customized layer for defining crop seeds or plants and a support layer 104 for supporting the customized layer. A conveying module 200 for moving the plants includes moving tracks 201 arranged on both sides laterally, allowing the moving tracks 201 to act on both sides of the planting unit 102. Several drive shafts 202 and driven shafts 203 are arranged at corner positions where the direction of movement changes on the moving tracks 201. The drive shafts 202 support the moving tracks 201 and provide power to them, while the driven shafts 203 support the moving tracks 201, thus defining a movement path for cyclic or reciprocating movement via the drive shafts 202 and driven shafts 203.

[0039] Preferably, in order to make full use of vertical space to improve the planting efficiency per unit area and to effectively combine the motion structure and aeroponic technology to ensure the targeted and uniform nature of the aeroponic effect, in the case where the aeroponic system of this application is divided into several zones according to the different relative spatial positions between the set path of the conveying module 200 and at least some of the structures of the cultivation module 100 and / or the aeroponic module 300, the conveying module 200 carries the plants and moves back and forth and / or circulates along the set path between the several zones, so that the aeroponic module 300 performs aeroponic cultivation on the plants through the relative movement of at least some of its structures and the plants.

[0040] Specifically, the aeroponic system includes a first zone 204 where the set path of the conveying module 200 extends longitudinally along the culture module 100, a second zone 205 where the set path of the conveying module 200 undulates longitudinally along the culture module 100, and a third zone 206 where the set path of the conveying module 200 extends longitudinally along the aeroponic module 300. The set paths of the conveying module 200 in the first zone 204 to the third zone 206 are interconnected to form a motion path that can move back and forth or cyclically. The first zone 204 has the following layout: the moving track 201 of the conveyor module 200 is arranged in a near-parallel or fixed-angled manner with respect to the farm plane. This serves as an operation or observation plane, suitable for performing operations such as sowing, observation, intervention, and harvesting on plants, and forming an operation and intervention space. The second zone 205 has the moving track 201 of the conveyor module 200 arranged in an undulating manner at different heights to form a wave-shaped movement path that can make full use of vertical space. Combined with a light source, it can produce illumination light with periodic changes in the illumination angle, which can approximately simulate the illumination angle and intensity variation under natural sunlight. This is suitable for performing cultivation operations on plants and forming a light cultivation space. The third zone 206 has the moving track 201 of the conveyor module 200 arranged in a near-parallel or fixed-angled manner with respect to the farm plane. This allows the plants moving along the moving track 201 to move relative to the spray structure of the aeroponic module 300 to obtain uniform and effective aerosol cultivation. This is suitable for performing atomized spraying operations on plants and forming an atomized cultivation space.

[0041] Preferably, to ensure that the system can achieve effective functional zoning and avoid mutual interference, especially to prevent the mist used for aeroponics from spreading throughout the cultivation space and affecting light or damaging the equipment, the cultivation module 100 is provided with sealing plates 106 for physical separation between each zone, such as... Figure 2 and Figure 4As shown, the sealing plate 106 includes at least a first sealing plate arranged on the main frame 101 on both sides of the culture module 100. The first sealing plate is used to separate the culture space where the planting unit 102 is arranged and the equipment space where the drive shaft 202 and the driven shaft 203 are arranged. That is, the first sealing plate can physically isolate the moving track 201 of the conveying module 200 and the drive equipment, which can prevent the excessive humidity and impurities in the culture space from affecting the operating status and service life of the equipment. It can also wrap and protect the rotating equipment to avoid unexpected failures or accidents caused by impurities being accidentally drawn in. The sealing plate 106 also includes a second sealing plate arranged on both vertical sides of the cultivation module 100. The second sealing plate is used to isolate the lighting equipment and aeroponic equipment from the conveying cultivation equipment. The lighting equipment has a circuit and electronic structure. The second partition can isolate the high humidity environment of the cultivation space to avoid affecting the operation of the circuit and electronic equipment. The aeroponic equipment is used to generate mist and act on the plants. In order to ensure the targeted effect of the mist, it should be avoided that the mist is diffused throughout the entire cultivation space. Therefore, the second partition can be used to separate the light cultivation space and the mist cultivation space. While improving the targeted effect of the mist, it can also avoid the adverse effects of the mist on the light. A third sealing plate is also arranged on the outside of the space of the sealing plate 106. The third sealing plate is used to form a relatively closed aeroponic cultivation space, thereby limiting the mist diffusion range to the third zone 206 as much as possible to achieve targeted aeroponic cultivation. The first sealing plate has openings symmetrically distributed along the longitudinal axis in the transverse direction for connecting the drive shaft 202 and the driven shaft 203 to control the movement of the moving track 201; the second sealing plate has an opening for the movement of the planting unit 102 and the moving track 201, so that the moving track 201 carrying the planting unit 102 can move back and forth or circulate between the operation intervention space, the lighting cultivation space and the atomization cultivation space.

[0042] Preferably, the conveying module 200 is provided with a moving track 201 extending along a predetermined path. The moving track 201 is arranged on both sides of the main frame 101 laterally, so that the moving track 201 can carry the planting unit 102 along the predetermined path by connecting the two ends of the planting unit 102 arranged laterally. The planting unit 102 for arranging crop seeds and crop plants is provided with a planting layer 103 that provides positioning for the crop seeds and crop plants using a loose and porous structure, and at least a support layer 104 for supporting the planting layer 103. Specifically, the planting unit 102 for arranging crop seeds and crop plants is arranged laterally, such that both ends of the planting unit 102 are connected to the moving track 201 of the conveying module 200 and move with the moving track 201. To effectively fix crop seeds or plants, planting unit 102 is provided with a planting layer 103. The planting layer 103 can be made of lightweight, loose, and porous organic or inorganic materials, such as asbestos or organic polymer materials. This allows the planting layer 103 to provide a relatively stable surface environment for sowing and crop growth. The loose and porous shape of the planting layer 103 can also provide attachment guidance for crop root development, promote the root development speed under aeroponic conditions, and facilitate the growth and reproduction of aerial roots. Compared with pit-type planting layers, it can increase the number of roots propagated under the same conditions by at least 20%. The planting layer 103 is provided with a support layer 104 in the vertical direction. The support layer 104 can be a mesh structure made of metal or other materials. Without affecting the vertical development of the plant roots, the support layer 104 can support the weight of the planting layer 103 and the plant and transfer it to the planting unit 102 connected to the moving track 201. Crop seeds are sown in the planting layer 103. As the growth process progresses, the seed roots gradually protrude from the supporting layer 104 below the planting layer 103 and form roots that are directly exposed to the air.

[0043] Preferably, such as Figure 2As shown, within the first zone 204, the moving track 201 of the conveying module 200 extends along a set path, allowing the planting unit 102 carrying the plants to move relative to external sowing, harvesting, and other intervention equipment along the moving track 201. Specifically, the moving track 201 of the conveying module 200 extends longitudinally to form a movement path approximately parallel to or at a fixed angle to the farm plane. The planting unit 102 and plants carried by the moving track 201 move relative to external sowing, harvesting, and other intervention equipment. Crop seeds can be sown regularly within the planting unit 102. Regular sowing is suitable for crops with independent plant types and requirements for plant spacing, such as some varieties of forage, vegetables, and flowers. Compared to random sowing, regular sowing is carried out through additionally arranged sowing equipment. The sowing equipment controls the sowing parameters and performs sowing operations in the first zone 204. The sowing equipment can be stationary relative to the aeroponic system. The aeroponic system controls the regular movement of the moving track 201, allowing the moving track 201 to move relative to the sowing equipment to achieve regular sowing, which can significantly reduce the difficulty of controlling the sowing parameters of the sowing equipment. For example, in the case of alfalfa, the aeroponic system of this application sets the horizontal dimension of the planting unit 102 to 3 meters and the vertical dimension to 0.5 meters. The plants are sown in rows in the vertical direction with a row spacing of 6 centimeters. The plant spacing in the horizontal direction is controlled at 6 centimeters. This can achieve a yield of more than 2 kilograms of alfalfa per square meter, and the cultivation cycle is shortened by more than 3 times compared with land planting.

[0044] Preferably, within the second zone 205, the moving track 201 of the conveyor module 200 receives light in an undulating motion between a first height and a second height, allowing crops in the planting unit 102 connected to the moving track 201 to undergo photocultivation through periodic changes in the light illumination angle. Specifically, the moving track 201 of the conveyor module 200 is arranged longitudinally in an undulating manner to form a wave-like movement path at an angle to the farm plane. The planting unit 102 and plants carried by the moving track 201 move relative to the lighting equipment and receive light for cultivation. The lighting equipment is arranged at the top vertically, and the moving track 201 of the conveyor module 200 carries the planting unit 102, which receives light from the lighting equipment in an undulating motion between a first height and a second height, allowing crops in the planting unit 102 to undergo photocultivation through periodic changes in the light illumination angle. Specifically, within the second zone 205, the conveying module 200 arranges drive shafts 202 or driven shafts 203 at a first height and a second height, respectively. The drive shafts 202 or driven shafts 203 at the first and second heights are spaced apart longitudinally, causing the moving track 201 connecting adjacent drive shafts 202 or driven shafts 203 to exhibit a wave-like undulating motion path. The first height is a position close to the lighting equipment, and the second height is a position far from the lighting equipment. The conveying module 200 arranges driven shafts 203 at the first height and a mixed arrangement of driven shafts 203 and drive shafts 202 at the second height. For example, at the second height, a group of drive shafts 202 is arranged at intervals of several groups of driven shafts 203, ensuring that the drive shafts 202 are evenly arranged longitudinally, allowing the moving track 201 to obtain a stable and continuous driving force. Adjust the arrangement interval of the driven shaft 203 and the drive shaft 202 in the first height and the second height so that the tilt angle of the moving track 201 relative to the vertical is controlled between 10 degrees and 70 degrees. For example, for crops with large leaf canopy and plant shape, the angle between the moving track 201 and the vertical can be appropriately increased to reduce the slope of the moving track 201, thereby ensuring that the lighting equipment can effectively illuminate the edge area of ​​the planting unit 102.

[0045] Preferably, within the third zone 206, the moving track 201 of the conveying module 200 extends along a predetermined path and moves relative to several functional units and several atomizing units of the aeroponic module 300. This allows the aeroponic module to perform aeroponic cultivation on the plants carried by the planting unit 102 connected to the moving track 201 through at least a phased aeroponic action. The aeroponic action includes at least an aeroponic flow and a jet. The aeroponic flow refers to a mist-like flow formed by the aggregation of small droplets, while the jet refers to a fluid formed by large droplets and continuous liquid. Specifically, the moving track 201 of the conveying module 200 extends longitudinally to form a movement path that is approximately parallel to or at a fixed angle to the farm plane. The planting unit 102 and plants carried by the moving track 201 move relative to the aeroponic equipment to receive aeroponic cultivation. The moving track 201 in the third zone 206, together with the moving tracks 201 connecting the first space and the second space, forms a movement path that can move back and forth or cyclically. When the moving track 201 of the conveyor module 200 carries the plants in a cyclical motion from the first zone 204 to the second zone 205 to the third zone 206 and back to the first zone 204, the transmission belt of the third zone 206 can carry the plants to interact with several auxiliary devices and spraying devices of the aeroponic module 300 in sequence to achieve a uniform and effective wetting effect of the mist on the plants.

[0046] To overcome the defects of excessively dense or entangled roots causing external dampness and internal dryness, as well as insufficient saturation, the aeroponic module 300 is equipped with a first functional unit 301 for combing and manipulating the plant roots and a first atomizing unit 302 for atomization cultivation in conjunction with the first functional unit. The atomization cultivation by the first atomizing unit 302 in conjunction with the first functional unit 301 is carried out by a combination of spraying the plant roots that have been separated by the first functional unit 301 with atomized mist flow and / or jet generated by the first atomizing unit 302 in several directions. The first functional unit 301 is provided with a horizontal bar 3011 for combing and stirring the plant roots. The horizontal bar 3011 can be adjusted in height by several adjusting rods. The first atomizing unit 302 is provided with at least a first nozzle 3021 and a second nozzle 3022 that emit mist or jets from two angles for combined spraying. Several first nozzles 3021 and several second nozzles 3022 are arranged in a transverse direction and are placed on both sides of the horizontal bar 3011 located on the longitudinal projection axis.

[0047] Specifically, the aeroponic module 300 is provided with a first functional unit 301 for combing and manipulating the plant roots. The first functional unit 301 is arranged in a way that allows for adjustable working height, so that the first functional unit 301 can perform combing operations on different crop roots or different growth stages of the same crop roots. In conjunction with the root-grooming operation of the first functional unit 301, the aeroponic module 300 is equipped with a first atomizing unit 302 for atomizing the plant roots that have been intervened by the first functional unit 301. The first atomizing unit 302 atomizes the plant roots through jets and / or mist flows at several angles. That is, the first functional unit 301 is used to comb and disperse the plant roots, while the first atomizing unit 302 atomizes the plant roots during the combing process. The atomizing effect includes mist flow and jet. Mist flow refers to the mist-like flow formed by the aggregation of small droplets, and jet refers to the fluid formed by large-sized droplets or continuous liquid. This allows the aeroponic module 300 to use auxiliary structures to solve the problems of plant root entanglement and external wetness and internal dryness.

[0048] Furthermore, the first functional unit 301 and the first atomizing unit 302 utilize structural arrangement and operational coordination to implement aerosol cultivation, for example, as... Figure 3As shown, the first functional unit 301 is located at the connection between the third zone 206 and the second zone 205, that is, the first functional unit 301 is located at one longitudinal end of the aeroponic module 300, so that the first auxiliary module can perform a sorting operation on the plants that have just entered the third zone 206. The first functional unit 301 includes a horizontal bar 3011 that directly contacts the plant roots and extends laterally. The two ends of the horizontal bar 3011 are connected to the second adjusting rods 3014 that are placed on both sides of the aeroponic module 300 laterally. The second adjusting rods 3014 are connected to the first adjusting rods 3013 arranged on the main frame 101. The first adjusting rods 3013 and the second adjusting rods 3014 are used to adjust the arrangement position of the horizontal bar 3011, and the arrangement position includes at least the arrangement height. When the crossbar 3011 approaches the planting unit 102 supported by the moving track 201, the crossbar 3011 can comb through the plant roots protruding from the support layer 104. The plant moves longitudinally under the action of the moving track 201, so that the plant roots move relative to the crossbar 3011. The height of the crossbar 3011 is located at the lower part of the support layer 104 of the planting unit 102, so that the height of the crossbar 3011 is greater than the height of the lower end of the plant roots. Then the plant roots of the planting unit 102 sweep across the crossbar 3011 in sequence and use the pushing action of the crossbar 3011 to open the inside of the plant roots. While improving the distribution of the plant roots, it can also provide conditions for the aerosol to act on the inside of the plant roots. The first atomizing unit 302 is arranged on the lower longitudinal side of the first functional unit 301. In order to ensure that the first atomizing unit 302 can more fully wet the plant roots that are disturbed by the first functional unit 301, the first atomizing unit 302 includes at least a number of first nozzles 3021 and a number of second nozzles 3022 that can emit mist or jets from two angles. The number of first nozzles 3021 and the number of second nozzles 3022 are arranged to extend laterally. For example, the first nozzle 3021 is located on one side of the longitudinal projection axis of the crossbar 3011, and is used to generate an aerosol flow or jet in the first direction to act on the plant roots located on one side of the longitudinal direction of the crossbar 3011. The second nozzle 3022 is located on the other side of the longitudinal projection axis of the crossbar 3011, and is used to generate an aerosol flow or jet in the second direction to act on the plant roots located on the other side of the longitudinal direction of the crossbar 3011. Then the first atomizing unit 302 can make full use of the opening space created by the crossbar 3011 moving the plant roots through the aerosol flow or jet in the first and second directions, so that the aerosol flow or jet can effectively enter the plant roots. Moreover, the aerosol flow or jet acting on both sides of the crossbar 3011 can act on both sides of the same batch of plant roots, thereby achieving uniformity of aerosol action.

[0049] Furthermore, in order to enable the horizontal bar 3011 to effectively comb through the root system during the process of parting the plant roots to increase the area of ​​aerosol application, the first functional unit 301 is provided with a baffle 3012 on one vertical side of the horizontal bar 3011 to expand the range of aerosol flow or jet application. The aerosol flow or jet acting on the baffle 3012 can form an aerosol flow or jet with an expanded application range by utilizing the reflection effect of the baffle 3012 and act on the plant roots on both longitudinal sides of the horizontal bar 3011. Specifically, the first functional unit 301 has a baffle plate 3012 for expanding the range of action of the mist or jet at the vertical part of the crossbar 3011. The baffle plate 3012 is arranged to extend laterally, so that the longitudinal projection axis of the baffle plate 3012 is located between the first nozzle 3021 and the second nozzle 3022 of the first atomizing unit 302. Then, the mist or jet generated by the first atomizing unit 302 in the first direction points from the first nozzle 3021 to the baffle plate 3012 on the side closer to the first nozzle 3021. The mist or jet acting on the baffle plate 3012 can form a mist or jet with an expanded range of action by the reflection effect of the baffle plate 3012 and act on one side of the plant root system supported by the crossbar 3011. The second direction of the mist or jet generated by the first atomizing unit 302 is directed by the second nozzle 3022 towards the side of the baffle 3012 near the second nozzle 3022. The mist or jet acting on the baffle 3012 can form a mist or jet with an expanded range of action by the reflection effect of the baffle 3012 and act on the other side of the plant roots that have passed the crossbar 3011. This allows the plant roots of the planting unit 102 to pass over the crossbar 3011 in batches, and the plant roots of the same batch to receive the mist or jet reflected by the baffle 3012 on both sides of the crossbar 3011 in turn. Thus, the uniformity of the mist effect received by the plant roots inside and outside the plant is improved by the combined action of the first functional unit 301 and the first atomizing unit 302.

[0050] Preferably, to effectively solve the problem that the crossbar 3011 cannot effectively separate plant roots into several batches due to root entanglement, the crossbar 3011 of the first functional unit 301 can be structurally designed. The crossbar 3011 of the first functional unit 301 is provided with a comb-like structure, wherein the crossbar 3011 has several radially protruding ridges on its circumferential surface, and the height of the ridges protruding from the surface of the crossbar 3011 gradually changes along the axial direction. The ridges are arranged laterally at intervals along the crossbar 3011, so that the ridges can be placed between adjacent roots and use the relative movement of the roots to comb through the knotted positions. For example, the crossbar 3011 of the first functional unit 301 has several radially protruding ridges on its circumferential surface, and the height of the ridges protruding from the surface of the crossbar 3011 gradually changes along the axial direction. The ridges are arranged laterally at intervals along the crossbar 3011, so that the ridges can serve as a comb structure inserted between adjacent roots and used to comb through knots by the relative movement of the roots. Furthermore, the movement of the crossbar 3011 relative to the plant roots can be achieved by the longitudinal movement of the plant carried by the moving track 201. The crossbar 3011 can also be configured to actively rotate under the action of the second adjusting rod 3014. The linear velocity generated by its rotation is opposite to the direction of movement of the moving track 201, so that the crossbar 3011 can increase the relative movement speed between the comb structure of the crossbar 3011 and the plant roots by actively rotating, thereby enhancing the combing effect of the crossbar 3011 without interfering with the speed of movement of the plant carried by the moving track 201. In addition, the combing effect of the crossbar 3011 on the plant root system will also clear away the weak and residual roots inside the plant root system, ensuring the growth space of the new and healthy roots, and using the combing process to ensure appropriate root spacing, thereby effectively promoting the development of the plant root system and improving the aerosol efficiency of the plant root system.

[0051] Preferably, the first functional unit 301 and the first atomizing unit 302 can effectively wet the plant roots protruding from the support layer 104 through the upward airflow or jet. However, for plant roots that have not yet protruded from the support layer 104 or for plant roots located within the custom layer, the upward airflow or jet can only contact the surface of the custom layer and cannot effectively penetrate into the interior of the custom layer. Furthermore, the action time of the first functional unit 301 and the first atomizing unit 302 is limited, making it difficult to achieve a good and continuous penetration effect. Therefore, the atomization module 300 is provided with a second functional unit 303 for defining the action channel range of the airflow or jet and a second atomizing unit 304 for atomization cultivation in conjunction with the second functional unit 303. The atomization cultivation by the second atomizing unit 304 in conjunction with the second functional unit 303 is carried out by the second atomizing unit 304 spraying the action channel defined by the second functional unit 303 through a combination of airflow and / or jet generated at several positions. The second functional unit 303 is provided with a guide plate 3031 that extends longitudinally and is arranged at an angle, so that the atomizing module 300 uses the guide plate 3031 to form an aerosol flow and / or jet whose effective range gradually decreases in the opposite direction to the moving direction of the moving track 201. The second atomizing unit 304 is provided with a plurality of nozzles arranged at least at the ends and middle of the effective flow channel, so that the aerosol flow and / or jet generated by the plurality of nozzles moves at least in the opposite direction to the movement direction of the moving track 201 of the conveying module 200.

[0052] like Figure 3As shown, the aeroponic module 300 of this application is provided with a second functional unit 303 extending longitudinally along the aeroponic module 300. The second functional unit 303 is used to form a flow channel that limits the range of aerosol flow, thereby improving the targeting of the aerosol effect. The aeroponic module 300 is also provided with a second atomizing unit 304 in conjunction with the second functional unit 303 for generating an aerosol flow or jet into the flow channel formed by the second functional unit 303. Specifically, the second functional unit 303 is arranged downstream of the first functional unit 301. In order to narrow the range of the aerosol flow channel and improve the targeting of the aerosol effect, the second functional unit 303 is provided with a guide plate 3031 extending longitudinally along the aeroponic module 300. The guide plate 3031 is inclined to the farm plane, so that the second functional unit 303 uses the inclined guide plate 3031 to form a flow channel whose flow range gradually narrows in the opposite direction to the moving direction of the moving track 201. This allows the flow channel to overcome the decrease in aerosol concentration caused by the aerosol flow acting on the plants or equipment and maintain the aerosol at a high concentration level. The second atomizing unit 304, configured in conjunction with the second functional unit 303, is equipped with a third nozzle 3041 and a fourth nozzle 3042. The third nozzle 3041 generates an aerosol flow at the inlet of the flow channel formed by the guide plate 3031, while the fourth nozzle 3042 generates an aerosol flow in the middle of the flow channel. This allows the aerosol flow generated by the fourth nozzle 3042 to supplement the aerosol flow generated by the third nozzle 3041, thus ensuring the aerosol concentration within the flow channel in conjunction with the structural design of the second functional unit 303. When the moving track 201 carries the plant and moves longitudinally within the flow channel, the aerosol concentration is... The airflow moving in the opposite direction to the movement of the moving track 201 is generated by the third nozzle 3041 and the fourth nozzle 3042 of the second atomizing unit 304 and continuously flows through the flow channel. The relative movement between the plant and the airflow promotes the wetting effect of the airflow on the plant roots. The airflow contacts the plant leaf area and the equipment, condenses and flows into the planting layer 103, and is stored by utilizing the loose and porous structure of the planting layer 103. This allows the second functional unit 303 and the second atomizing unit 304 to promote the full penetration of the airflow into the planting layer 103 and provide sufficient nutrition to the roots within the planting layer 103. The aeroponic module 300 is also equipped with a nutrient solution recovery and treatment tank. The remaining part of the airflow or jet generated by the first atomizing unit 302 and the second atomizing unit 304 after acting on the plant condenses and drips. The inclined arrangement of the guide plate 3031 of the second functional unit 303 collects the condensed and dripped nutrient solution into the recovery and treatment tank.

[0053] Based on the above, this application uses several functional units and several atomization units of the aeroponic module 300 to perform aeroponic cultivation under intervention. The intervention includes combing and moving the plant roots that protrude from the support layer 104 and limiting the flow channel of the aeroponics. However, as the plant roots develop, they gradually fill the holes of the support layer 104, making it difficult for the aeroponics in contact with the support layer 104 to penetrate into the planting layer 103 above the support layer 104. That is, the blocking effect of the plant roots and gravity will further hinder the aeroponics from penetrating into the planting layer 103 from bottom to top. The aeroponics acting from the side is also difficult to break through the side structure of the planting unit 102 and penetrate into the planting layer 103. Therefore, for crops whose entire root system is located within the planting layer 103, or for crops in the early stages of root development where the roots have not yet protruded from the support layer 104, the aerosol flow and jets acting from the bottom or sides are unlikely to effectively penetrate the surface barrier of the planting unit 102 and penetrate into the planting layer 103 in large quantities. The surface barrier includes the obstruction of solid structures and the surface water film. For specific varieties and in the early stages of growth where all or most of the roots are located within the planting layer 103, the aeroponic system of this application also includes an aerosol unit for top-down aerosol cultivation. This overcomes the defect that the aerosol flow and jets acting from the bottom or sides are unlikely to effectively penetrate the surface barrier of the planting unit 102 and penetrate into the planting layer 103 in large quantities, ensuring that the aeroponic system of this application is also well-suited for situations where, due to variety factors or the early stages of crop growth, all or most of the plant's roots are located within the planting layer 103.

[0054] Preferably, such as Figures 2 to 4As shown, the aeroponic module 300 is equipped with a third atomizing unit 305 for emitting a mist or jet from top to bottom. The third atomizing unit 305 can be arranged in the first zone 204 near the second zone 205, so that the crop after being treated by the third atomizing unit 305 can enter the second zone 205 to receive light cultivation. Thus, the aeroponic cultivation of the plant by the third atomizing unit 305 can avoid the adverse effects of the mist and jet on light irradiation, while ensuring the nutrient supply for the crop to carry out light cultivation in the second zone 205, thereby improving the coordination and consistency of aeroponic cultivation and light cultivation. To provide sufficient space for intervention in the first zone 204, the third atomizing unit 305 can also be arranged in the third zone 206 near the first zone 204. After the action of the first atomizing unit 302 and the second atomizing unit 304, the plant roots located outside the planting layer 103 can obtain better aerosol cultivation. Thus, the third atomizing unit can act on the plant roots located within the planting layer 103, especially for cases where all or most of the plant roots are located within the planting layer 103. Specifically, the third atomizing unit 305 is arranged on the vertical side of the conveyor track, so that the planting units 102 moving along the conveyor track pass sequentially on the vertical side of the third atomizing unit 305. The third atomizing unit 305 includes several fifth nozzles 3051 arranged at intervals in the horizontal direction. The fifth nozzles 3051 are connected to pipes arranged in the horizontal direction, so that the several fifth nozzles 3051 can collaboratively or independently emit aerosol streams and / or jets to the planting units 102 distributed in the horizontal direction. To ensure that the mist or jet stream is concentrated on the planting unit 102 and avoids diffusion that leads to a dispersed effect, the fifth nozzle 3051 should be positioned close to the planting layer 103. However, this would hinder plant growth. Therefore, the planting layer 103 of the planting unit 102 is provided with several horizontally spaced dividing grooves 105, such that the center lines of the dividing grooves 105 are aligned with the projections of the fifth nozzles 3051 of the third atomizing unit 305 onto the planting layer 103. In other words, the positions of the dividing grooves 105 leave space for the mist to act on the fifth nozzles 3051. The dividing grooves 105 extend longitudinally along the planting layer 103, allowing the planting unit 102 to move longitudinally along the moving track 201 while maintaining alignment between the dividing grooves 105 and the fifth nozzles 3051. This allows the third atomizing unit 305 to mist the moving planting unit 102 without disturbing the plants.

[0055] Preferably, the third atomizing unit 305 acts on the planting layer 103 from top to bottom. The dividing groove 105 on the planting layer 103 provides aerosol space for the fifth nozzle 3051 of the third atomizing unit 305, allowing the fifth nozzle 3051 to apply aerosols, including aerosol flow and jets, to the dividing groove 105 and both sides of it. The dividing groove 105 can also temporarily store the nutrient solution generated by the aerosol flow and jets acting on the planting layer 103, allowing the nutrient solution to gradually penetrate into the planting layer 103 and act on the plant roots. The dividing groove 105 on the planting layer 103 can also provide operational space for intervention. Since no plants are placed at the dividing groove 105 location, the plant is divided into several areas laterally. Therefore, the location of the dividing groove 105 is not only used for aerosol culture but also for observing and intervening in the development or disease status of the plant's leaf areas. To increase the uniformity of the aerosol effect of the third aerosol unit on the planting unit 102, the planting layer 103 may also be provided with a number of longitudinally spaced partition grooves 105, so that the longitudinally spaced partition grooves 105 and the transversely spaced partition grooves 105 are connected. The longitudinally spaced partition grooves 105 serve as auxiliary flow channels to promote the flow efficiency of nutrient solution on the surface of the planting layer 103, so that the nutrient solution generated by the aerosol effect of the third aerosol unit 305 can evenly cover the planting layer 103 and penetrate into the interior of the planting layer 103.

[0056] Example 2

[0057] This embodiment provides an aeroponic factory based on an aeroponic system. The aeroponic system of this application can be used as a sub-module of an aeroponic factory for the efficient and automated cultivation of crops such as forage, vegetables, and flowers. Figure 1As shown, to achieve automated cultivation in an aeroponic factory based on the aeroponic system of this application, the system includes an intelligent module 400 for adjusting the automated aeroponic cultivation process, at least a motion unit 401 for controlling the transmission module 200, at least a nutrient unit 402 for controlling the aeroponic module 300, at least a monitoring unit 403 for detecting the aeroponic process, and an interactive device 404 for information input and output. The intelligent module 400 uses a chip processor as its hardware carrier and is data-connected to the motion unit 401, nutrient unit 402, monitoring unit 403, and interactive device 404, making the intelligent module 400 the information center of the aeroponic system and aeroponic factory to coordinate and control the automated aeroponic process. The motion unit 401 is used to control the motion parameters of the transmission module 200, including motion state, motion cycle, motion speed, etc.; the nutrient unit 402 is used to control several functional units and atomization units of the aeroponic module 300 to carry out aeroponic cultivation, and the nutrient unit 402 can also be used to control lighting equipment; the monitoring unit 403 obtains aeroponic process parameters through several sensors arranged in the system to assist the intelligent module 400 in issuing instructions to the motion unit 401, the nutrient unit 402, and the interactive device 404.

[0058] Preferably, the intelligent module 400 and the motion unit 401 control the transmission module 200 to move via external commands or preset schemes obtained from the interactive unit 404 and aeroponic cultivation process information obtained from the monitoring unit 403. External commands include control commands directly input by the administrator or externally transmitted control commands. The preset scheme is an optimized cultivation scheme set for the plants. The aeroponic cultivation process information includes plant growth status information, plant environment information, and equipment status information. To be applicable to different stages of aeroponic cultivation, which include at least a sowing stage, several cultivation stages, an intervention stage, and a harvesting stage, the transmission module 200 is equipped with at least several movement modes applicable to different stages based on at least one of the movement state, movement speed, or movement direction. The movement state includes the start / stop state of the conveyor belt and the duration of start / stop, i.e., the transmission module 200 can move continuously or intermittently. Continuous movement ensures the uniformity and continuity of light received by the plants, but is not conducive to sowing, harvesting, and intervention. Intermittent movement ensures that each planting unit 102 stays in the first zone 204 for a sufficient time to obtain sufficient time for sowing, harvesting, and intervention. The movement speed is mainly determined by the relative movement of the plant and several functional units and atomizing units of the aeroponic module 300, ensuring that the plant receives uniform and effective aerosol treatment. The movement direction is mainly the direction of reciprocating and cyclical movement of the conveyor module 200, such as the longitudinal direction on both sides in reciprocating movement and the clockwise or counterclockwise direction in cyclic movement.

[0059] Preferably, the aeroponic module 300 mainly functions in several cultivation stages of aeroponic cultivation. However, since the atomizing units of the aeroponic module 300 have different directions and parameters of aerosol action on the plants, the aeroponic module 300 calls upon several atomizing units to perform aerosol action at different cultivation stages. The directions of aerosol action include upward, lateral, and downward, corresponding to the directions of aerosol action of the first atomizing unit 302 to the third atomizing unit 305, respectively. This allows the directions of aerosol action of the first atomizing unit 302 to the third atomizing unit 305 to be applicable to different cultivation stages and combined to form a three-dimensional aeroponic cultivation. The aerosol action parameters include action interval, action angle, action pressure, action flow rate, and action ratio. The action interval refers to the time interval between two actions; the action angle refers to the specific action angle of the nozzle; the action pressure is the nozzle spray pressure, which determines the movement speed of the aerosol flow and jet; and the action ratio is the ratio of the action flow rate of the aerosol flow to the action flow rate of the jet. For example, the cultivation stages may include a primary growth stage, an intermediate growth stage, and a high-level growth stage. For the initial growth stage where crop seeds and plant roots are entirely within the planting layer 103, the aeroponic module 300 mainly uses aerosols through the second aerosol unit 304 and the third aerosol unit 305. For the intermediate growth stage where plant roots are partially located within the planting layer 103 but protrude beyond it, the aeroponic module 300 uses aerosols through the first aerosol unit 302 to the third aerosol unit 305. For the advanced growth stage where most of the plant roots protrude beyond the planting layer 103, the aeroponic module 300 mainly uses aerosols through the first aerosol unit 302 and the third aerosol unit 305.

[0060] Preferably, the intelligent module 400 and the nutrient unit 402 control the aeroponic module 300 to perform aerosol spraying through external instructions or preset schemes obtained by the interactive unit 404 and aeroponic planting process information obtained by the monitoring unit 403. The aeroponic module 300 performs aerosol spraying by selectively calling several functional units and several atomizing units, and adjusting one or more of the aerosol spraying parameters of the corresponding atomizing units. For example, when the aeroponic module 300 calls the first functional unit 301 and the first atomizing unit 302 to perform aerosol spraying, the crossbar 3011 of the first functional unit 301 combs and moves the plant roots, so that the nozzle of the first atomizing unit 302 can perform aerosol spraying on the plant roots under the action of the crossbar 3011. To achieve both economy and targeted application of the aerosol effect, the nozzle of the first atomizing unit 302 employs intermittent aerosol application. Because the plant roots are divided into several batches by the combing and guiding action of the crossbar 3011 and pass through it sequentially, the plant roots do not pass through the crossbar 3011 continuously. The current batch of plant roots is gradually lifted by the crossbar 3011, changing from a drooping state to an inclined state, and then returning to a drooping state after reaching a certain height. In the inclined state, the aerosol acts on the side of the plant roots closest to the crossbar 3011; when returning to the drooping state, the aerosol acts on the other side, ensuring that the aerosol application of the first atomizing unit 302 covers both sides of the plant roots and guarantees uniformity of the aerosol application. During the process of the plant roots changing from a drooping state to an inclined state and then back to a drooping state, the nozzles in the first atomizing unit 302 emit mist and jets that simultaneously act on different batches of plant roots located on both sides of the crossbar 3011. The continuous plant movement process can be transformed into a discontinuous movement process by the first functional unit 301, coordinating with the discontinuous spraying of the first atomizing unit 302 to achieve a misting effect. The action interval of the nozzles in the first atomizing unit 302 is determined based on the time interval between batches of plant roots passing the crossbar 3011. The time interval between batches of plant roots passing the crossbar 3011 is determined by the movement speed of the moving track 201, the length of the plant roots, and the arrangement height of the crossbar 3011. The length of the plant roots is obtained by the monitoring unit 403. The action angle of the nozzles in the first atomizing unit 302 is determined based on the arrangement height of the crossbar 3011, ensuring that the mist or jet emitted by the nozzles can act on the spoiler 3012 and be reflected to the maximum extent. The operating pressure and flow rate of the first atomizing unit 302 can be determined according to a preset scheme. The operating ratio within the first atomizing unit 302 is set differently according to the plant cultivation stage and adjusted according to the root length of the plant.In the initial growth stage, the plant roots have not yet protruded beyond the planting layer 103, so a first ratio is used, where the effective flow rate of the aerosol stream is greater than that of the jet stream, for example, 80% for the aerosol stream and 20% for the jet stream. In the intermediate growth stage, the plant roots partially protrude beyond the planting layer 103 and are relatively fragile, so a second ratio is used, where the effective flow rate of the aerosol stream is greater than or equal to that of the jet stream, for example, 60% for the aerosol stream and 40% for the jet stream. In the advanced growth stage, most of the plant roots protrude beyond the planting layer 103 and are relatively long, so a third ratio is used, where the effective flow rate of the aerosol stream is less than that of the jet stream, for example, 30% for the aerosol stream and 70% for the jet stream. This ensures that the effective ratio within the first atomization unit 302 is suitable for the plant root length at the current cultivation stage.
