Description

Technical Field

[0001] This invention relates to the field of agricultural cultivation technology, specifically to a rose cultivation system and method oriented towards root oxygen regulation. Background Technology

[0002] In the large-scale cultivation of crops such as modern roses, in order to improve the utilization rate of greenhouse space, connected seedbeds or three-dimensional circulating cultivation structures are usually adopted. In these systems, the cultivation carrier and planting density are usually fixed when the garden is established, and the plants grow for a long period of time in a predetermined spatial location.

[0003] However, due to the physical constraints of fixed planting density and connected structures, as the planting years progress and the plant canopy widens, the plants gradually compete with each other for living space and sunlight and air in the local microenvironment. Coupled with the unavoidable mechanical damage during daily operations, the product quality declines significantly from the second planting year. In the third year, the proportion of high-grade products drops sharply to about 30%, and the proportion of weakened and aging plants reaches as high as 70%. Once this competitive disadvantage is established, it shows an irreversible trend. The limited growth of the above-ground nutrients directly hinders the development of the underground root system, leading to the decline of root function.

[0004] Meanwhile, existing cultivation systems lack effective bottom-level intervention methods to address root weakness caused by spatial competition. For example, in a circulating cultivation structure, water and fertilizer operations are usually carried out only by surface spraying at fixed workstations. This shallow supply applied from the top cannot effectively transport water and oxygen to the deep substrate. This not only leads to a long-term state of insufficient water and oxygen supply for deep roots, but also fails to specifically improve the root zone environment damaged by spatial competition. Ultimately, this results in the continuous accumulation of plant weakness and a continuous deterioration in the overall output quality of the system. Summary of the Invention

[0005] The purpose of this invention is to provide a rose cultivation system for root oxygen regulation, which aims to solve the problem that oxygen-enriched liquid is difficult to achieve uniform diffusion in the deep root region.

[0006] To achieve the above objectives, the present invention provides a rose cultivation system oriented towards root oxygen regulation, the system comprising: A cultivation rack, on which a drive module is provided; A mobile module, comprising a set of mobile wheels and a set of mobile chains, wherein the set of mobile wheels is connected to the output end of a drive module, and the set of mobile chains is movably mounted on the cultivation rack via the set of mobile wheels. A cultivation module is mounted on the moving chain assembly. The cultivation module includes several cultivation trays for cultivating roses. The control module is located on one side of the cultivation rack. The control module includes a root oxygen unit and a control unit. The root oxygen unit contains a cultivation solution. The control unit is used to control the oxygen content of the rose roots in the cultivation tray during the movement of the moving chain assembly. The control unit includes: A parameter acquisition subunit is used to acquire the position parameters of the cultivation tray and the environmental parameters of the rose root system. A logic processing subunit is communicatively connected to the parameter acquisition subunit, and the logic processing subunit is used to acquire root oxygen regulation instructions based on the environmental parameters; A logic control subunit is communicatively connected to the logic processing subunit and electrically connected to the drive module and the root oxygen unit, respectively. The logic control subunit is used to control the start / stop state of the drive module and the working state of the root oxygen unit according to the position parameters and root oxygen regulation commands.

[0007] Optionally, the moving wheel assembly includes a pair of moving gears arranged in parallel and movably disposed on the inner side of the cultivation rack, the moving chain assembly includes a pair of moving chains arranged in parallel, the moving chains being disposed on the outer periphery of the moving gears, and the output end of the drive module being connected to the moving gears.

[0008] Optionally, the cultivation module further includes a movable rod and a pair of fixed plates, the fixed plates being disposed on the movable chain, the movable rod being disposed between the two fixed plates, and the cultivation tray being disposed on the movable rod.

[0009] Optionally, the root oxygen unit includes a liquid tank, a pump set, and several spray sets. The cultivation solution is placed in the liquid tank. One end of the pump set is connected to the liquid tank, and the other end is connected to the spray sets. The spray sets are set on the cultivation rack, and the outlet end of the spray sets matches the highest position of the cultivation tray.

[0010] Optionally, the spray assembly includes a nozzle and a spray pipe, the nozzle and the spray pipe are connected, and several spray pipes are all connected to the output end of the pump assembly. The spray assembly also includes a rotating base, which is rotatably mounted on the cultivation rack, and several spray pipes are all mounted on the rotating base.

[0011] Optionally, the parameter acquisition subunit includes a position sensor and a root system sensor group; The position sensor is installed on the cultivation rack and is used to detect whether the cultivation tray moves with the moving module to the working position that matches the root oxygen unit. The root sensor group is installed in the internal matrix of the cultivation tray. The root sensor group is used to acquire environmental parameters of the rose root system, including root moisture content data and dissolved oxygen data.

[0012] Optionally, the root oxygen unit further includes a mixing subunit, which is electrically connected to the logic control subunit. The logic processing subunit is configured with a water shortage threshold and an oxygen deficiency threshold. When the logic processing subunit determines that the dissolved oxygen data is lower than the oxygen deficiency threshold, it generates an oxygen enrichment regulation command. The logic control subunit controls the mixing subunit to turn on according to the oxygen enrichment regulation command to increase the dissolved oxygen content of the cultivation solution.

[0013] Optionally, the root oxygen unit further includes a rotating motor electrically connected to the logic control subunit; when the position sensor detects that the cultivation tray has reached the highest position, the logic control subunit controls the drive module to pause or decelerate, and controls the output pressure of the root oxygen unit and the rotation angle of the rotating motor according to the moisture content data and dissolved oxygen data.

[0014] To achieve the above objectives, the present invention also provides a rose cultivation method oriented towards root oxygen regulation, the method comprising the following steps: The control drive module operates, driving the moving module to move cyclically on the cultivation rack, so that each cultivation tray rotates in sequence. Acquire the location parameters of the cultivation tray and the environmental parameters of the rose root system, including moisture content data and dissolved oxygen data; When the cultivation tray is moved to the highest position according to the position parameters, the current physiological state of the root system is determined according to the moisture content data, dissolved oxygen data and preset water shortage threshold and oxygen deficiency threshold, and a corresponding root oxygen regulation command is generated. The start / stop status of the drive module and the working status of the root oxygen unit are controlled according to the position parameters and root oxygen regulation commands.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention solves the technical problems of existing connected seedbeds or three-dimensional structures, which are limited by fixed planting density, leading to systemic physiological decline caused by plants competing for sunlight and air in a fixed space. It also addresses the issue that existing cultivation systems typically use shallow surface spraying, making it difficult for oxygen-rich liquids to diffuse evenly in the deep root zone. This invention achieves an automated, cyclical cultivation mode that decouples dynamic and static elements, promoting the growth of roses in each pot. This results in a more efficient and controlled cultivation process. The invention also addresses the issue of the root oxygen content of roses due to the fixed output of a moving wheel assembly connected to a moving wheel assembly, and the need for centralized regulation of the oxygen content of the rose roots during the movement of the cultivation trays by the moving wheel assembly. The seasonal movement of the rose bushes within the greenhouse space, via the mobile chain assembly, significantly mitigates the spatial disadvantages caused by fixed locations and breaks the vicious cycle of limited above-ground nutrients leading to irreversible decline in the underground root system. Furthermore, by separating the sap supply source and control center from the mobile cultivation trays and centrally fixing them aside, the design eliminates the high risk of leakage associated with laying complex water supply networks on the three-dimensional mobile structure. It also allows for the centralized configuration of high-precision control equipment, enabling precise and centralized dynamic control of the sequentially passing cultivation trays at specific physical spatial nodes. Without increasing the complexity of the system's dynamic network, this effectively improves the long-term water and oxygen supply to the deep roots of the rose bush, providing a solid underlying hardware support for long-term, large-scale cultivation.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0019] In the large-scale greenhouse cultivation of crops such as modern roses, especially in long-cycle cultivation operations using connected seedbeds or three-dimensional structures, high-density arrangement is required to maximize the initial output ratio of greenhouse space.

[0020] However, existing conjoined cultivation techniques typically employ fixed planting densities and cultivation media. As the planting years progress and the plant canopy expands, the plants gradually compete for living space and sunlight and air within their local microenvironments. Furthermore, in traditional cultivation systems, water replenishment usually relies on continuous surface spraying or drip irrigation. This passive regulation not only makes it difficult to evenly deliver water to the deeper layers of the substrate, but also leads to the root system being in a state of chronic water-oxygen antagonism and hypoxia. The limited competition for nutrients above ground and the hypoxic decline of the deep root system intertwine, causing a significant decline in product quality starting from the second planting year. By the third year, the proportion of high-grade products can even drop to around 30%, while the proportion of weakened and aging plants increases. Once weakness is established, it triggers irreversible systemic physiological deterioration.

[0021] As attached Figure 1 and Figure 2 As shown, this embodiment provides a rose cultivation system oriented towards root oxygen regulation, the system comprising: Cultivation rack 1, wherein a drive module 11 is provided on cultivation rack 1; The mobile module 2 includes a mobile wheel set 21 and a mobile chain set 22. The mobile wheel set 21 is connected to the output end of the drive module 11, and the mobile chain set 22 is movably mounted on the cultivation rack 1 via the mobile wheel set 21. Cultivation module 3, which is disposed on the mobile chain group 22, includes a plurality of cultivation trays 33, which are used for cultivating roses; The control module 4 is located on one side of the cultivation rack 1. The control module 4 includes a root oxygen unit 41 and a control unit. The root oxygen unit 41 contains a cultivation solution. The control unit is used to control the oxygen content of the rose roots in the cultivation tray 33 during the movement of the moving chain group 22.

[0022] Based on the above problems, this embodiment provides a rose cultivation system for root oxygen regulation, aiming to solve the long-term physiological decline caused by the fixed spatial layout of connected seedbeds in traditional greenhouses. It is particularly suitable for solving the problem of the difficulty in achieving uniform diffusion of oxygen-enriched liquid in the deep root area. The cultivation system specifically includes a cultivation rack 1, which serves as the physical support base for the entire automated operation. A drive module 11, which provides the core power source, is firmly installed on the rack. It is understood that the drive module 11 is preferably a drive motor with a reducer and other structures. In order to realize the dynamic circulation of the plant population, a moving module 2 is introduced into the system. The moving module 2 includes a moving wheel set 21 and a moving chain set 22. The moving wheel set 21 is directly or indirectly mechanically connected to the power output end of the drive module 11, thereby converting the rotational power into traction force. The moving chain set 22 is movably set on the cultivation rack 1 through the moving wheel set 21, forming a closed three-dimensional circulating rotation path.

[0023] On top of this circulating structure, a cultivation module 3 is set up to support the rose plant. The cultivation module 3 is attached to and fixedly mounted on the moving chain assembly 22. Similarly, the cultivation module 3 is preferably directly and detachably connected to the moving chain assembly 22 by means of hooking, snapping, or other methods. The cultivation module 3 includes several independent cultivation trays 33, and the interior of the cultivation trays 33 is filled with substrate for cultivating rose plants. This structural design allows each potted rose to periodically change position within the three-dimensional space of the greenhouse as the moving chain assembly 22 operates. This greatly alleviates the disadvantage of long-term competition between plants for local sunlight and air caused by fixed planting density, and breaks the vicious cycle of limited above-ground nutrients and irreversible decline of underground root systems. To precisely intervene in the rhizosphere microenvironment of these moving roses, a control module 4 is positioned at a specific location on one side of the cultivation rack 1. The control module 4 includes a root oxygen unit 41 and a control unit. The root oxygen unit 41 contains a nutrient-rich cultivation solution that can be used for subsequent oxygenation. The core function of the control unit is to perform non-contact or piercing-type centralized dynamic control of the oxygen content and moisture status of the rose roots in the cultivation trays 33 at specific physical spatial nodes during the continuous or intermittent movement of the moving chain assembly 22. This decoupling design eliminates the risk of leakage from laying complex water supply networks on the moving parts and allows for the centralized configuration of high-precision control equipment.

[0024] In this embodiment, the movable wheel assembly 21 includes a pair of movable gears 211, which are parallel and movably disposed on the inner side of the cultivation rack 1. The movable chain assembly 22 includes a pair of movable chains 221, which are disposed on the outer periphery of the movable gears 211. The output end of the drive module 11 is connected to the movable gears 211.

[0025] It should be noted that the moving wheel set 21 is further defined as including a pair of moving gears 211, which are parallel and movably arranged on the inner side of the cultivation rack 1, playing a key guiding and power transmission role. In conjunction with this set of gears, the moving chain set 22 is represented as a pair of moving chains 221, which are tightly fitted around the outer periphery of the moving gears 211, forming a meshing transmission. At this time, the power output end of the drive module 11 is directly or through a reduction mechanism connected to the moving gears 211, thereby driving the entire moving chain set 221 to circulate on the three-dimensional track planned on the cultivation rack 1.

[0026] It should also be noted that the meshing transmission of gears and chains inevitably produces a polygonal effect, which in turn causes continuous low-frequency mechanical vibrations during system operation. Normally, efforts are made to eliminate these vibrations to achieve smooth operation; however, in this embodiment, this unavoidable mechanical characteristic is utilized and transformed into a core agronomic method for passively and physically improving the microenvironment of the rose root system. As the cultivation tray 33 circulates on the cultivation rack 1 along with the moving chain 221, the periodic micro-oscillations generated by the meshing of gears and chains are continuously transmitted to the cultivation substrate inside the cultivation tray 33 through the physical structure.

[0027] During long-term rose cultivation, the continuous expansion of the root system and the downward pressure of gravity from frequent irrigation water inevitably lead to the compaction and hardening of the cultivation substrate, resulting in a significant decrease in microporosity. This all-weather low-frequency micro-vibration, generated by the cyclical movement, promotes continuous microscopic relative displacement of the substrate particles, breaking down the dense structure formed by surface tension and adhesion between particles. This continuous physical loosening and substrate mixing not only effectively slows down the substrate hardening process but, more importantly, also promotes the release of numerous micropores within the substrate. This allows oxygen-rich air in the greenhouse to naturally penetrate into the deep root zone through these vibration-expanded pores before the cultivation tray 33 reaches the fixed control module 4, thus achieving a passive increase in basic oxygen content and a significant improvement in soil quality along the circulation path.

[0028] In this embodiment, the cultivation module 3 further includes a movable rod 31 and a pair of fixed plates 32. The fixed plates 32 are disposed on the movable chain 221, the movable rod 31 is disposed between the two fixed plates 32, and the cultivation tray 33 is disposed on the movable rod 31.

[0029] Understandably, the pairs of fixed plates 32 are securely mounted on the parallel moving chains 221 on both sides. These fixed plates 32 are typically made of galvanized steel plates treated for corrosion and rust prevention, or high-strength industrial-grade nylon injection molded parts. They are fixed at equal intervals to specific outer links of the moving chains 221 using high-strength bolts, riveting, or direct welding, allowing the fixed plates 32 to tightly engage with the chain and move in a completely synchronized cycle as the chain rotates. Between the two corresponding fixed plates 32, a movable rod 31 is suspended, and the cultivation tray 33 is securely mounted on this movable rod 31. In actual mechanical construction, the two ends of the movable rod 31 are typically nested within pre-drilled holes in the two fixed plates 32 via damping flange bearings, universal joints, or highly wear-resistant hinge pins. This allows for free rotation at multiple angles between the two fixed plates 32, with the connection points at both ends as the horizontal axis.

[0030] It is also understandable that, since the cultivation tray 33 itself, as well as the substrate, water, and rose plant inside it, are physically positioned directly below the rotation axis of the movable rod 31, the movable rod 31 will, like a pendulum, overcome the slight frictional resistance of the bearings at both ends under the natural vertical force of gravity, and always maintain a vertically downward posture, thus keeping the cultivation tray 33 on a relatively horizontal working surface at all times. This is because the center of gravity of the cultivation tray 33, as well as the center of gravity of the substrate, water, and rose plant, is specially positioned directly below the rotation axis of the movable rod 31.

[0031] This gravity-adaptive leveling mechanism of the movable rod 31 eliminates the risk of tipping over that may occur when the cultivation tray 33 travels through the three-dimensional space. It ensures that the bulk substrate, oxygen-enriched nutrient solution, and fragile rose capillary roots in the cultivation tray 33 will not spill when crossing dead angles of the chain drive. At the same time, it ensures that the stems of the rose plants can maintain an upward natural phototropic growth trend without being disturbed by the operating posture of the equipment, thus avoiding the plants consuming unnecessary physiological repair energy due to frequent changes in gravity direction.

[0032] More importantly, during system operation, the rigid meshing of the moving gear 211 and the moving chain 221 inevitably produces a polygonal effect, which in turn triggers low-frequency mechanical micro-vibrations. These continuous vibration waves travel along the fixed plate 32 fastened to the chain, through the bearing structures at both ends of the movable rod 31, and along this rigid or semi-rigid physical transmission path, continuously transmitting to the cultivation tray 33 placed on it. In long-term rose cultivation scenarios, the substrate often becomes dense and compacted due to the vigorous growth of the root system and the gravitational pressure of repeated irrigation, resulting in a severe imbalance in the air-water ratio. However, it is precisely through this continuous physical micro-oscillation caused by the system's circulation and transmitted at high frequency through the movable rod 31 that continuous microscopic relative displacement and friction occur between the substrate particles inside the cultivation tray 33.

[0033] This sustained transfer of physical kinetic energy, without contacting the plant surface, breaks down the hardened crust formed between particles due to surface tension and binders from within the substrate. This causes the substrate to release a large number of micropores, essentially performing a continuous loosening of the substrate along the entire assembly line circulation path. This allows natural air from the greenhouse environment to penetrate into the deep root zone ahead of time through these micropores widened by physical vibration. Thus, before the cultivation tray 33 reaches the fixed control module 4 for active high-pressure water-air penetration, this ingenious mechanical linkage has already completed the physical improvement and passive oxygenation of the underlying soil. This significantly reduces the difficulty of breaking the crust and the fluid resistance during the subsequent active spraying by the control unit, constructing a robust technical barrier for this cultivation system to maintain the vitality of the rhizosphere micropores through a purely mechanical structure in long-term, high-density agricultural production.

[0034] In this embodiment, the root oxygen unit 41 includes a liquid tank 411, a pump set 412, and several spray sets. The cultivation liquid is placed in the liquid tank 411. One end of the pump set 412 is connected to the liquid tank 411, and the other end is connected to the spray sets. The spray sets are set on the cultivation rack 1, and the outlet end of the spray sets matches the highest position of the cultivation tray 33.

[0035] Understandably, the liquid tank 411 serves as the physical source of water, fertilizer, and oxygen supply for the entire system. It contains a pre-mixed cultivation solution rich in nutrients and dissolved oxygen required for rose growth. This liquid tank 411 is typically made of food-grade high-density polyethylene storage tank with good light-proof and corrosion-resistant properties, or a large-capacity rust-proof stainless steel mother liquor tank. This ensures that the physicochemical properties of the cultivation solution remain absolutely stable during long-term storage, effectively preventing the growth of internal algae and the corrosion and precipitation of fertilizer salts caused by external light.

[0036] To transform the static cultivation solution in the liquid tank 411 into a regulating medium with directional penetrating kinetic energy, the system introduces a pump unit 412 as the power center for fluid transport. One end of the pump unit 412's inlet is tightly connected to the bottom or lower side of the liquid tank 411 via a high-pressure resistant industrial corrugated pipe or rigid PVC pipe, while the other end of its high-pressure output is connected to the subsequent spray unit via a main pipeline and a branch manifold system. To support the system's subsequent high-intensity intervention logic for deep root systems, the pump unit 412 is not a common low-pressure agricultural self-priming pump, but rather preferably a multi-stage centrifugal pump or a high-frequency plunger pump with an intelligent frequency converter. This high-specification power source configuration allows the system to output a wide range of pressure changes from gentle low-pressure penetration to high-pressure pulse jets within a millisecond time window, based on the underlying control commands, providing sufficient fluid power to thoroughly break up the substrate compaction layer.

[0037] Extending along the fluid pipeline, the spray assembly, serving as the output terminal for performing operations, is mounted on the fixed cultivation rack 1. When the moving chain assembly 22 drives the cultivation tray 33 to circulate along the three-dimensional track of the cultivation rack 1 and gradually climbs to the physical top of the vertical rotation trajectory, this area not only has the largest unobstructed operating clearance, but also, when the cultivation tray 33 crosses the top moving gear 211 here, its linear velocity in the vertical component undergoes a natural extreme value transition, forming a brief relative pause or gentle deceleration period. At this time, the spray assembly (which can be in the form of a high-pressure direct-fire nozzle or an anti-drip atomizing nozzle 4131 array made of corrosion-resistant alloy) fixed at a specific position at the top of the cultivation rack 1 has its outlet end directly facing the substrate surface of the cultivation tray 33 at the highest position.

[0038] In this embodiment, the spray assembly includes a nozzle 4131 and a spray pipe 4132. The nozzle 4131 and the spray pipe 4132 are connected. Several spray pipes 4132 are connected to the output end of the pump assembly 412. The spray assembly also includes a rotating base. The rotating base is rotatably mounted on the cultivation rack 1. Several spray pipes 4132 are mounted on the rotating base.

[0039] In some preferred embodiments, the rotating seat is movably and rotatably mounted on the crossbeam or fixed bracket at the highest position of the cultivation rack 1 via a high-precision flange bearing or a seated spherical bearing with waterproof and dustproof seals. The aforementioned nozzles 4132 are securely arranged side by side or in an array on the bearing surface of the rotating seat by customized fixing clamps or direct welding. When the system needs to intervene in the root zone microenvironment of the cultivation tray 33 that has been rotated to the highest position, the external servo motor or high-precision stepper motor will receive the angle adjustment command issued by the underlying control logic, thereby driving the rotating seat to perform precise pitch or lateral oscillation within a preset angle range (e.g., from 0 degrees vertically downward to 45 degrees left and right). At this time, all the nozzles 4132 and nozzles 4131 fixed on the rotating seat will also change their spatial orientation accordingly, realizing real-time stepless adjustment of the fluid spray angle.

[0040] In this embodiment, the control unit includes: A parameter acquisition subunit is used to acquire the position parameters of the cultivation tray 33 and the environmental parameters of the rose root system. A logic processing subunit is communicatively connected to the parameter acquisition subunit, and the logic processing subunit is used to acquire root oxygen regulation instructions based on the environmental parameters; The logic control subunit is communicatively connected to the logic processing subunit and electrically connected to the drive module 11 and the root oxygen unit 41, respectively. The logic control subunit is used to control the start / stop state of the drive module 11 and the working state of the root oxygen unit 41 according to the position parameters and root oxygen regulation commands.

[0041] In actual long-cycle agricultural cultivation scenarios, if the control unit uses a single and fixed high-pressure water flow or airflow to forcibly inject into the cultivation tray 33 based solely on the simple oxygen deficiency signal transmitted by the sensor, it will inevitably cause severe substrate splashing and loss on the dry and loose substrate surface. This problem also occurs in hydroponics. If the substrate is already in a dense and compacted state with high water content, the fixed high-pressure fluid will forcibly flush out fixed water short-circuit channels along the gaps of least resistance, resulting in a severe flow channel effect. This physical impact not only fails to allow the nutrient solution to penetrate evenly into the deep root system, but also fails to effectively expel harmful metabolic waste gases that have accumulated in the micropores at the bottom layer. Ultimately, this makes it difficult to substantially repair the so-called high-level weakened plant rhizosphere microenvironment. Therefore, this embodiment also provides a set of mathematical operation logic that can adapt to the current physical blockage state of the substrate and the physiological hypoxia depth of the plant, so that the fluid dynamics output by the control unit can just penetrate the compacted layer and replace the waste gas each time, without damaging the fragile capillary root system. Based on this, this embodiment incorporates the following targeted injection pressure adaptive control formula in the logic processing program of the control unit: ;

[0042] In the formula, The target spray pressure that should be applied to the designated cultivation tray 33, calculated by the control unit, is directly sent as a control command to the execution end of the root oxygen unit 41 and obtained in real time by the logic processing program inside the control unit. This represents the preset basic shell-breaking pressure constant of the cultivation substrate used in the cultivation tray 33. This constant is derived from the empirical fixed value manually entered during system initialization for the inherent physical compactness of different substrates such as peat or coconut coir. The oxygen deficiency compensation coefficient is a proportional constant used to adjust the weight of the dissolved oxygen difference on the overall injection pressure of the system. It is derived from the calibration data fitted by multiple greenhouse live calibration experiments before the system leaves the factory. This indicates the optimal dissolved oxygen threshold preset for the rose root system at the current growth stage. This data comes from the standard physiological requirements database of roses pre-stored inside the control unit. This indicates that the control unit obtains the current dissolved oxygen data in real time through the environmental sensor pre-embedded in the cultivation tray 33. This data directly reflects the real hypoxia predicament of the root microenvironment at this time, and comes from the real-time sampling feedback of the sensor. It represents the water resistance surge coefficient, used to quantify the weight of the physical repulsion force generated by the forced injection of external fluid due to the overload of water inside the matrix. It is derived from matrix physical property testing and fluid dynamics calibration experiments. The factor representing the decline in plant root density is a compensating variable that increases dynamically with the number of years of planting. It is used to characterize the dense physical barrier layer formed inside the substrate by the declining and aging roots after long-term planting in connected seedbeds. It is derived from the extrapolated data automatically accumulated by the system based on the planting cycle ledger. This indicates that the control unit synchronously acquires the current moisture content data inside the matrix in real time through the deep environment sensor, which comes from the real-time high-frequency sampling feedback of the moisture sensor; This represents the preset optimal moisture content threshold of the cultivation substrate under conditions of maintaining a good air-water ratio. This threshold is also derived from the optimal water-holding characteristic data entered for a specific substrate during system initialization.

[0043] Based on the above expression, it can be understood that the target spray pressure is equal to the base pressure, plus a linear proportional compensation term based on the degree of hypoxia, plus an exponential compensation term based on the degree of moisture content exceeding the standard and the degree of root aging. It can also be understood that the physical blocking characteristics of the rhizosphere microenvironment are not constant. The second term of the formula establishes a direct hypoxia-dynamic feedback mapping by introducing the ratio of the relative deviation between the current dissolved oxygen data and the optimal dissolved oxygen threshold. This means that when the hypoxia of the deep roots is more severe, the system will aggressively increase the target spray pressure proportionally, thereby giving the sprayed oxygen-enriched cultivation solution stronger physical penetration kinetic energy in order to break through the anaerobic layer that has hardened due to long-term hypoxia.

[0044] However, linear compensation alone is far from sufficient. The above expression also introduces an exponential resistance compensation mechanism based on the natural constant. In real long-term cultivation scenarios, when the current moisture content of the substrate exceeds the preset optimal moisture content threshold, the capillary pores inside the substrate will be completely sealed by liquid water. Furthermore, as the root density decay factor of the plant continues to increase, the aging roots will lock in this moisture like a dense filter. If a fluid carrying fresh oxygen is forcibly injected into the deep layers at this point, the physical resistance it faces will not increase linearly, but rather exhibit an extremely steep exponential surge. By multiplying the moisture difference by the root decline factor and using it as an exponent, the system enables the control unit to instantly calculate an extremely high target injection pressure with strong pulse characteristics when it detects extreme conditions of high humidity and severely aged and intertwined roots. This design, which relies purely on the underlying mathematical logic to link the hardware execution unit, gives the system physical breaking capabilities, allowing the high-speed oxygen-rich jet to squeeze into the deep pores blocked by water. Utilizing the principle of fluid mechanics incompressibility, it pushes the harmful metabolic waste gas trapped at the bottom upwards to the matrix surface as if driven by a piston. This dynamic composite logic not only avoids the inherent contradictions of low pressure ineffectiveness and high pressure causing flow channel effects, but also achieves unexpected technical effects—completely renovating the deep rhizosphere microenvironment of high-grade weakened plants and restoring the air-water ratio to balance—without using any additional chemical soil loosening agents, relying solely on the system's own intelligent fluid pressure pulse intervention.

[0045] In this embodiment, the parameter acquisition subunit includes a position sensor and a root system sensor group; The position sensor is installed on the cultivation rack 1, and the position sensor is used to detect whether the cultivation tray 33 moves with the moving module 2 to the working position that matches the root oxygen unit 41; The root sensor group is installed in the internal matrix of the cultivation tray 33. The root sensor group is used to acquire environmental parameters of the rose root system, including root moisture content data and dissolved oxygen data.

[0046] In this embodiment, the root oxygen unit 41 further includes a mixing subunit, which is electrically connected to the logic control subunit. The logic processing subunit is configured with a water shortage threshold and an oxygen shortage threshold. When the logic processing subunit determines that the dissolved oxygen data is lower than the oxygen shortage threshold, it generates an oxygen enrichment regulation command. The logic control subunit controls the mixing subunit to turn on according to the oxygen enrichment regulation command to increase the dissolved oxygen content of the cultivation solution.

[0047] In this embodiment, the root oxygen unit 41 further includes a rotating motor electrically connected to the logic control subunit; when the position sensor detects that the cultivation tray 33 has reached the highest position, the logic control subunit controls the drive module 11 to pause or decelerate, and controls the output pressure of the root oxygen unit 41 and the rotation angle of the rotating motor according to the moisture content data and dissolved oxygen data.

[0048] It should be noted that in the actual three-dimensional structural layout, the position sensor is precisely positioned on the cultivation rack 1. Typically, a high-frequency photoelectric switch or a non-contact Hall sensor is installed at the top crossbeam of the vertical rotation trajectory of the cultivation rack 1. The position sensor is used to detect in real time whether the cultivation tray 33 moves with the chain of the moving module 2 to the highest working position matching the spatial position of the root oxygen unit 41. Simultaneously, the root sensor array is deeply embedded in the internal substrate of the cultivation tray 33 in an array or sampling manner. In the complex agricultural microenvironment, the root sensor array is used to obtain the most accurate environmental parameters of the rose root system. These environmental parameters explicitly include moisture content data reflecting the dryness and wetness of the substrate and dissolved oxygen data reflecting the respiratory distress of the root zone.

[0049] After obtaining accurate underlying data, the system needs corresponding physical execution methods to change the physicochemical properties of the liquid. Therefore, the root oxygen unit 41 is also equipped with a mixing subunit. The mixing subunit is connected to the logic control subunit at high speed. The mixing subunit is usually a Venturi jet or a micro-nano bubble generator installed on the water inlet pipe of the pump group 412. The logic processing subunit is equipped with agronomically proven water shortage threshold and oxygen deficiency threshold. When the system is running, if the logic processing subunit determines by comparison that the dissolved oxygen data transmitted by the sensor is lower than the oxygen deficiency threshold, it will immediately generate a clear oxygen enrichment control command. Then, the logic control subunit will strictly control the mixing subunit to open according to the oxygen enrichment control command, using mechanical shearing or Venturi negative pressure effect to forcibly force greenhouse air or pure oxygen into and cut into the flowing liquid, thereby physically and instantly greatly increasing the dissolved oxygen content of the cultivation solution.

[0050] It should also be noted that when the position sensor accurately detects that the cultivation tray 33 has reached its highest position as it climbs with the chain, the logic control subunit will quickly issue an instruction to control the drive module 11 to pause or decelerate, so that the cultivation tray 33 forms a brief static control window period below the spray group. At this time, the system will not only calculate the output pressure according to the formula in the aforementioned embodiment, but also coordinate the output pressure of the root oxygen unit 41 and the rotation angle of the rotating motor according to the moisture content data and dissolved oxygen data.

[0051] Furthermore, in actual high-pressure intervention scenarios, if pump unit 412 outputs extremely high shell-breaking pressure, but nozzle 4131 maintains a fixed, vertically downward angle for rigid spraying, then this high-pressure jet will not only create a deep pit on the substrate surface, but the single-point high-pressure injection will also easily form a flow channel effect within the substrate. The oxygen-rich water will rapidly flow away along this single channel, making it impossible to achieve uniform lateral and oblique diffusion throughout the entire three-dimensional root space. Therefore, it is necessary to design an angle distribution logic coupled with physical pressure, so that the wetter and more oxygen-deficient the substrate, the wider the sweeping angle of nozzle 4131, thereby evenly distributing the local high-pressure kinetic energy to a wider substrate surface. This achieves multi-point shell breaking while protecting the root system from concentrated impact. Based on this in-depth agronomic and fluid mechanics cross-consideration, this embodiment innovatively incorporates the following dynamic rotation angle calculation formula for the rotating motor in the logic processing program: ;

[0052] In the formula, This indicates the target deflection sweep angle that the rotating motor should currently execute, calculated by the control unit. This value directly determines the physical amplitude of the lateral swing of the nozzle 4132 driven by the rotary table, and the unit is degrees. The preset base coverage angle of the spray unit when the substrate is in an ideal air-water ratio state is derived from the optical calibration value performed on the opening size of the cultivation tray 33 and the atomization cone angle of the nozzle 4131 before the system leaves the factory. This represents the moisture diffusion range compensation coefficient, which is used to quantify the physical resistance weight of the lateral diffusion of fluid when the matrix moisture content exceeds the standard. It is derived from the three-dimensional fluid simulation calibration data of the system based on the specific matrix permeability. The hypoxia tracking dispersion coefficient is a proportional constant used to adjust the weight of the influence of hypoxia depth on the system's spray coverage area. It is derived from the fitting results of multiple greenhouse living root distribution patterns.

[0053] In the above expression, the second term of the formula squares the ratio of the current moisture content data to the optimal threshold. When the cultivation tray 33 is in a state of severe waterlogging, all the pores of the substrate are blocked by water. At this time, the natural lateral diffusion ability of the high-pressure oxygen-enriched water after being injected into the substrate is almost reduced to zero. Therefore, once the moisture content is detected to be excessive, this logic will force the motor to rotate and perform a wide-range sweep at an angle that is multiplied, forcing the high-pressure jet to perform forced large-area multi-point puncture in physical space, thereby completely eliminating the flow channel effect that is most likely to be caused in the state of waterlogging.

[0054] Meanwhile, the third term of the formula introduces the logic of a natural logarithmic function that includes the difference between the current dissolved oxygen data and the optimal threshold. When the root microenvironment just shows signs of hypoxia, the initial slope of the logarithmic curve is relatively large, and the system will react quickly by appropriately increasing the sweeping angle of the rotating motor to ensure that fresh oxygen can cover a wider shallow root system as soon as possible. However, when the degree of hypoxia reaches an extremely severe state of deep depletion, the latter part of the logarithmic curve gradually flattens out, which matches the physiological vulnerability of the root system of severely hypoxic plants. It effectively prevents the phenomenon of excessive swing angle of the rotating motor due to the pursuit of extreme oxygen supply, which would cause the high-pressure jet to spray out of the boundary of the cultivation tray 33 and waste resources.

[0055] Through this set of pure mathematical logic to precisely control the hardware, the system can autonomously adjust the high-pressure small-angle or low-pressure large-angle sweeping within a very short pause window according to the actual mud and suffocation level in the pot. This not only pushes the deep and uniform penetration of the oxygen-rich liquid to the extreme, but also uses multi-angle continuous physical flushing to completely expel the harmful waste gas that has been trapped at the bottom of the substrate for a long time from the cultivation tray 33.

[0056] As attached Figure 3 As shown, this embodiment provides a rose cultivation method oriented towards root oxygen regulation, the method including the following steps: The control drive module 11 operates, driving the moving module 2 to move cyclically on the cultivation rack 1, so that each cultivation tray 33 rotates in sequence. Acquire the positional parameters of the cultivation tray 33 and the environmental parameters of the rose root system, including moisture content data and dissolved oxygen data; When the cultivation tray 33 is moved to the highest position according to the position parameters, the current physiological state of the root system is determined according to the moisture content data, dissolved oxygen data and preset water shortage threshold and oxygen deficiency threshold, and a corresponding root oxygen regulation command is generated. The start / stop state of the drive module 11 and the working state of the root oxygen unit 41 are controlled according to the position parameters and root oxygen regulation commands.

[0057] In the above method steps, the underlying cyclic flow scheduling is first executed, that is, the drive module 11 is controlled to operate, driving the moving module 2 to move cyclically on the cultivation rack 1, so that each cultivation tray 33 rotates in sequence. In actual long-term agricultural operation, the control unit will send continuous or intermittent operating pulses to the drive module 11, so that the cultivation tray 33 changes its spatial position in three-dimensional space like an assembly line. This step fundamentally breaks the fixed local microenvironment in the greenhouse connected structure, ensuring that each rose can obtain natural light from the top and air circulation in the greenhouse equally, avoiding physiological decline of plants caused by being in a disadvantaged space for a long time.

[0058] Throughout the entire lifecycle of the cultivation tray 33 as it circulates with the chain, the system synchronously performs high-frequency data monitoring steps, namely acquiring the positional parameters of the cultivation tray 33 and the environmental parameters of the rose root system, including moisture content data and dissolved oxygen data. Through a photoelectric position sensor pre-installed on the top of the cultivation rack 1, the system can accurately track which numbered cultivation tray 33 is about to enter the control position; simultaneously, a sensor network embedded deep in the substrate continuously transmits data back to the main control unit during the movement. This allows the system to grasp the current drought, waterlogging, or suffocation status of each rose root system before any intervention occurs, providing a detailed data foundation for subsequent targeted regulation.

[0059] Based on the acquired underlying data, when the cultivation tray 33 is determined to have moved to its highest position according to the position parameters, the system judges the current physiological state of the root system based on the moisture content data, dissolved oxygen data, and preset water and oxygen deficiency thresholds, and generates corresponding root oxygen regulation instructions. In this judgment process, water and oxygen are cross-referenced. For example, when sufficient water is detected but deep dissolved oxygen is extremely low, the system accurately diagnoses this as a precursor to root rot caused by substrate compaction and water seal. It then calls upon the precisely calculated target spray pressure and target deflection sweep angle from the aforementioned embodiment to package and generate a unique oxygen-enrichment intervention instruction sequence specific to this particular rose bush.
