Description

Technical Field

[0001] This invention relates to the field of smart agriculture and plant cultivation technology, specifically a method for quality control of edible chrysanthemums based on a smart garden cultivation box. Background Technology

[0002] As a plant used for both food and medicine, the market value of edible chrysanthemum depends not only on its yield but also on its appearance (such as the vibrancy of its flower color) and internal quality (such as the content of flavor compounds and nutrients). Traditional garden cultivation methods rely entirely on personal experience, with an uncontrollable environment, making it impossible to precisely regulate quality.

[0003] While existing greenhouse cultivation technologies offer some degree of environmental control, their complex systems and high costs make them unsuitable for small-scale backyard settings. Existing patent document CN117546709A discloses an intelligent ecological cultivation system and its usage method, comprising a cultivation box (comprising a cultivation substrate, cultivation rack, cultivation container, and diffused glass); a water and fertilizer integration device (comprising a water tank, fertilizer tank, water pump, conduit, drip irrigation pipe, and soil moisture sensor); and a plant light source (comprising LED plant lights and light sensors). System operating data is preset in the controller; data is acquired in real-time from sensors and transmitted back to the controller. The controller analyzes the data and sends control commands to the LED plant lights and / or the water and fertilizer integration device to control their operation. This cultivation technology utilizes a substrate with excellent granular structure and strong water and fertilizer retention capacity; the diffused glass ensures uniform light distribution; the primary lighting scheme, using sunlight supplemented by LED plant lights, effectively reduces carbon emissions; the drip irrigation pipe offers high water-saving efficiency and irrigation uniformity; and it has high potential for widespread application in home gardening.

[0004] While the device offers numerous benefits, it still suffers from the following drawbacks: The system lacks targeted regulatory logic for specific crops (such as edible chrysanthemums) to ensure quality development. It cannot apply specific environmental interventions (such as light quality control and water stress) at the most sensitive growth stages based on different quality objectives (flower appearance, flavor, nutrition), leading to homogenized cultivation results and failing to meet users' personalized needs. Furthermore, existing technologies primarily focus on increasing yield, lacking a refined regulatory method for home users that allows for simple operation and significant improvement of various quality indicators in edible chrysanthemums.

[0005] Therefore, developing a method that is closely integrated with an intelligent cultivation box and can be automatically executed by the system or triggered by a user with a single click, thereby achieving targeted improvement of the quality traits of edible chrysanthemums, has significant application value. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems by providing a method for quality control of edible chrysanthemums based on an intelligent garden cultivation box. This method can automatically regulate the microenvironment within the box according to user needs through a preset program, thereby achieving targeted optimization of the flower color, flower shape, plant shape, and nutrient content of edible chrysanthemums.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: According to one aspect of the present invention, a method for quality control of edible chrysanthemums based on an intelligent garden cultivation box is provided, the method comprising the following steps: S1. Quality control target setting and mode selection: Through the human-computer interaction interface, users set the information of the cultivated edible chrysanthemum variety and the expected quality target, and select the pre-stored control mode. S2. Real-time data monitoring: Real-time monitoring of environmental data within the cultivation box through intelligent cultivation box; S3. Intelligent growth stage recognition: Based on the cumulative effective photoperiod data after planting, the current growth stage of edible chrysanthemum is automatically recognized; S4. Quality-oriented regulation: Based on the regulation mode selected in step S1 and the growth stage identified in step S3, the controller of the intelligent cultivation box calls the pre-stored environmental parameter model to precisely intervene in the environment inside the cultivation box. S5. Feedback and Optimization: During the regulation process, environmental parameters are continuously monitored to ensure they remain stable within the target range. Users can view the regulation progress through the human-computer interaction interface and conduct subjective flavor evaluations after harvesting. Based on historical data and evaluation results, the preset model parameters can be self-learned and optimized.

[0008] Preferably, in step S1, the control mode includes a flower-viewing priority mode, a flavor-priority mode, and a nutrition-priority mode; the flower-viewing priority mode aims to make the flowers brightly colored and large; the flavor-priority mode aims to reduce bitterness and enhance sweetness; and the nutrition-priority mode aims to maximize the content of anthocyanins, total phenols, vitamins, amino acids, trace elements, and other substances in the petals.

[0012] Preferably, for the flavor-priority mode, flavor optimization regulation is performed in the middle and late stages of bud formation: after identifying the 7th to 10th day of the bud formation period, a mild water stress program is initiated: the mild water stress program is to control the precision irrigation system to reduce the volumetric water content of the substrate from the conventional 60%-70% to 40%-50%, and maintain this mild drought state for 5-7 days.

[0013] Preferably, for the nutrient-priority mode, nutrient enhancement regulation is implemented in the early stage of harvest, and a compound stress induction program is initiated 7-10 days before the scheduled harvest date; the compound stress induction is to simultaneously implement light quality regulation and mild water stress.

[0014] Preferably, the light quality modulation is to increase the UV-B band at a dose of 2.5-5 μmol / m² / s for 2-3 hours daily; the mild moisture stress is to reduce the matrix moisture content to 45%-55%.

[0015] Preferably, the intelligent cultivation box includes a box body, a plurality of support frames are provided on the inner wall of the box body, a substrate is provided at the top of the support frames, a loading mechanism is provided between the substrate and the support frames, a door is provided on the outer side of the box body, and an exhaust device is provided at the bottom of the side wall of the box body; and a control mechanism is provided on the inner wall of the box body.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention combines the regulation of the quality traits of edible chrysanthemums, such as shape, color, taste, and nutrition, with the management of specific and programmable environmental factors (light quality, water stress), and precisely targets the most sensitive developmental period, achieving a shift from "relying on nature" to "customized on demand".

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the invention, and these aspects of the invention can be achieved even without these specific details.

[0023] Please see Figure 1 This embodiment of a method for quality control of edible chrysanthemums based on an intelligent garden cultivation box includes the following steps: S1: Goal Setting and Mode Selection Steps Through the human-computer interaction interface, which includes but is not limited to mobile APP, smartwatch / bracelet, and Bluetooth headset, users set information about the edible chrysanthemum variety to be cultivated and the desired quality goals. The system then selects a pre-stored control mode accordingly. The pre-stored control modes include a flower-priority mode, a flavor-priority mode, and a nutrition-priority mode. The flower-priority mode aims to produce bright colors and large flowers. The flavor-priority mode aims to reduce bitterness and enhance sweetness. The nutrition-priority mode aims to maximize the content of anthocyanins, total phenols, vitamins, amino acids, trace elements, and other substances in the petals.

[0024] S2: Real-time Data Monitoring Steps The cultivation box uses a built-in sensor array, such as an ambient temperature and humidity sensor, a substrate volumetric moisture content sensor, a substrate EC value sensor, a light quality and photoperiod integrated sensor, and a plant height monitoring sensor, to monitor and collect the following environmental data in real time: substrate humidity, light intensity / photoperiod, ambient temperature, and air humidity.

[0025] S3: Intelligent Recognition Steps for Growth Stages The intelligent controller automatically identifies the current growth stage of edible chrysanthemums based on the accumulated effective photoperiod data after planting: vegetative growth stage, flower bud differentiation stage, flower bud formation stage, petal color development stage, and pre-harvest stage.

[0026] The cumulative effective photoperiod is achieved by the daily accumulation of the daily light integral (DLI). The formula for calculating DLI is: DLI = PPFD × light hours × 3600 / 10 6 Among them, PPFD is the photosynthetic photon flux density (unit: μmol / m² / s), which is monitored in real time by an integrated light quality and photoperiod sensor; the number of illumination hours is the effective illumination duration (hours) of the day.

[0027] When the cumulative effective photoperiod is 240-280 mol / m², the intelligent controller automatically identifies it as the vegetative growth stage, characterized by rapid growth of roots, stems, and leaves, accumulating nutrients. When the cumulative effective photoperiod is 320-360 mol / m², it is the flower bud differentiation stage, characterized by the growth point transitioning from differentiating leaf buds to differentiating flower buds, beginning to form flower buds. This is a critical period determining the quantity and quality of flowers. When the cumulative effective photoperiod is 400-450 mol / m², it is the flower bud formation stage. When the cumulative effective photoperiod is 460-480 mol / m², it is the petal color development stage, characterized by fully open flowers, entering the viewing period. When the cumulative effective photoperiod is ≥485 mol / m², it is the pre-harvest stage.

[0028] Table 1. Photoperiod corresponding to each growth stage of edible chrysanthemum S4: Quality-Oriented Control Steps Based on the control mode selected by S1 and the growth stage identified by S3, the intelligent controller calls the pre-stored environmental parameter model and sends instructions to the actuator to precisely intervene in the environment inside the cultivation box.

[0029] By comparing the real-time collected "data" with the "standards" set by the model, the differences are identified, and the data regulation of the microenvironment is ultimately guided.

[0030] (1) Determine the environmental parameters to be compared 1) Temperature: including daytime temperature and nighttime temperature; 2) Humidity: Relative humidity of the air; 3) Illumination: Illumination intensity, photoperiod; 4) Substrate moisture.

[0031] (2) Establish an environmental parameter model An environmental parameter model was established through literature review and planting records.

[0032] (3) Compare the data Set an "acceptable deviation range" for each environmental parameter. When real-time data exceeds this range, the system will automatically trigger an alarm.

[0033] For the flower-viewing priority mode, color enhancement regulation is implemented during the petal color development period: After recognizing the entry into the petal color development period, a light quality regulation program is initiated: the LED supplemental lighting system is controlled to provide an additional 2-4 hours of specific light quality illumination on top of the daily basic illumination, with the energy ratio of blue light (450-470nm) and ultraviolet A light (320-400nm) increased to 15%-30% of the total light intensity. This operation can significantly stimulate anthocyanin synthesis, making the petal colors more vibrant. After light quality regulation using blue light (450-470nm) and ultraviolet A light (320-400nm), the flowering rate of edible chrysanthemums can be increased to 85%-92%, compared to 65%-70% in the unregulated group (natural light), representing an increase of 20%-27%. The anthocyanin content in the petals can reach 1.2-1.8 mg / gFW (fresh weight), compared to 0.6-0.9 mg / gFW in the unregulated group, representing an increase of 100%-150%. After regulation, the red a value of the petals increased from 15-20 to 25-30, and the color saturation (C) increased from 20-25 to 30-35.

[0034] For the flavor-priority mode, flavor optimization and regulation were implemented in the mid-to-late stages of bud formation: A mild water stress program was initiated 7-10 days after the onset of bud formation. This involved controlling the precise irrigation system to reduce the substrate's volumetric water content from the usual 60%-70% to 40%-50%, maintaining this mild drought state for 5-7 days. This operation induced the production of secondary metabolites in the plants, helping to reduce the accumulation of bitter substances (such as some terpenes) while increasing soluble sugar content and enhancing sweetness. Tests showed that under the flavor-priority mode, the soluble sugar content of edible chrysanthemum after water stress treatment increased from approximately 110-112 mg / gFW in the control group to 165-179 mg / gFW after stress treatment. This 50-60% increase in soluble sugar content directly enhanced the perceived sweetness of edible chrysanthemum, improved its texture, and simultaneously inhibited the synthesis of bitter substances such as terpenes, resulting in a more balanced flavor.

[0035] To address the nutrient-priority model, nutrient enhancement and regulation were implemented in the pre-harvest period: 7-10 days before the scheduled harvest date, a combined stress induction program was initiated, simultaneously implementing light quality regulation (increasing UV-B band dosage to 2.5-5 μmol / m² / s, 2 hours daily) and mild water stress (reducing substrate moisture content to 45%-55%). This combined stress synergistically activated the plant's defense mechanisms, significantly increasing the content of antioxidants such as anthocyanins, total phenols, and flavonoids in the petals. The anthocyanin, total phenolic, and flavonoid contents in edible chrysanthemum petals were detected using HPLC, Folin-Ciocalteu method, and aluminum nitrate colorimetric method, respectively. Three parallel tests were conducted, and the mean results are shown in Table 2.

[0036] Table 2 As shown in Table 2, under the nutrient priority mode of edible chrysanthemum, the use of a compound stress induction program (UV-B 2.5-5 μmol / m² / s for 2 hours daily + matrix moisture content of 45%-55%) can increase the content of anthocyanins, total phenols and flavonoids in petals by 100%, 63.6% and 59.1% respectively, significantly enhancing its nutritional value and antioxidant function.

[0037] S5: Feedback and Optimization Steps During the regulation process, the system continuously monitors environmental parameters to ensure they remain stable within the target range. Users can view the regulation progress through the app and conduct subjective flavor evaluations after harvest. The system can self-learn and optimize preset model parameters based on historical data and evaluation results.

[0038] See Figures 2-9 The intelligent cultivation box for edible chrysanthemums in the garden according to this embodiment includes: two support frames 2 slidably connected to the inner wall of the box body 1. In this embodiment, the box body 1 is made of glass and can be divided into three layers. A substrate 3 is provided at the top of the support frame 2. A loading mechanism 200 is provided between the substrate 3 and the support frame 2. A door 4 is provided on the outside of the box body 1. An exhaust device 5 is provided at the bottom of the side wall of the box body 1. The adjustment mechanism 100 is located between the two support frames 2 and the inner wall of the housing 1, and can adjust the spacing between the support frames 2; The control mechanism 300 is located on the inner wall of the housing 1 and can control the components on the inner wall of the housing 1.

[0039] It is worth noting that, in order to adjust the spacing of the support frame 2, the adjustment mechanism 100 specifically includes: a base plate 101 welded to the top of the inner wall of the housing 1, a rotating groove a102 opened at the top of the base plate 101, a screw a103 rotatably connected to the inner wall of the rotating groove a102, an external thread a104 opened on the outer periphery of the screw a103, a handle a105 welded to the outer periphery of the screw a103, and a limit block a106 welded to the top of the screw a103. In order to prevent the screw a103 from rotating too flexibly, which would cause the support frame 2 to move unstablely, silicone oil is applied to the inner wall of the rotating groove a102, which can limit the rotation of the screw a103 and prevent the support frame 2 from pressing the screw a103, causing the screw a103 to rotate on its own. The rotating groove b107 is located at the top of the support frame 2, and the top of the screw a103 is threaded to the inner wall of the rotating groove b107. The space of the lowest layer can be adjusted by rotating the screw a103.

[0040] Next, to adjust the space of the three layers, specifically, the adjustment mechanism 100 also includes: multiple rotating grooves c111 formed at the top of the two support frames 2; screws b112 threadedly connected to the inner walls of the multiple rotating grooves c111; multiple external threads b113 formed on the outer periphery of the screws b112; some external threads b113 and others having opposite helical directions; a handle b114 welded to the outer periphery of the screws b112; and multiple limiting blocks b115 welded to both ends of the screws b112. Multiple limit blocks b115 are placed at the outer end of the rotating groove c111, which can simultaneously control the movement of the two support frames 2; simultaneously controlling handle a105 and handle b114 can adjust the distance of the three layers; when handle b114 is controlled alone, due to the limitation of screw a103, it is difficult for the user to rotate screw b112, which can prevent accidental contact; the anti-spiral structure is self-locking, which can prevent the support frame 2 from moving; when handle a105 is controlled alone, due to screw b112, the two support frames 2 can move in unison.

[0041] Meanwhile, in order to limit the maximum spacing of the support frame 2, specifically, the top of the two support frames 2 are provided with limit grooves 121, the inner walls of multiple limit grooves 121 are slidably connected with limit rods 122, the two ends of the limit rods 122 are welded with limit blocks c123, and multiple limit blocks c123 are placed at the outer end of the limit grooves 121 to prevent the middle layer spacing from being too large.

Roller balls 204 are rolledly connected to the inner wall of the bottom of the multiple loading boxes 203. The side walls of the roller balls 204 are rolledly connected to the inner wall of the chute 202. Handles c205 are welded to the side walls of the multiple loading boxes 203. Multiple drainage holes 206 are opened at the bottom of the multiple loading boxes 203. In order to prevent excessive water leakage, a filter screen can be installed in the drainage hole 206. A baffle 207 is welded to the inner wall of the multiple loading boxes 203. An observation window 208 is opened on the side wall of the multiple loading boxes 203. The baffle 207 can ensure that the substrate 3 is far away from the bottom of the observation window 208 and can reduce the bottom area of ​​the loading box 203, which facilitates the rapid accumulation of moisture and makes it easier to observe.

[0043] Meanwhile, to supplement the lighting, specifically, multiple loading boxes 203 are bolted to the top of electric push rods b21, and multiple electric push rods b21 are bolted to the bottom of LED light holders 22, with LED lights installed on the LED light holders.

[0044] Meanwhile, in order to replenish water, specifically, the inner wall of the loading box 203 is laid with multiple seepage pipes 31, the water inlet end of the multiple seepage pipes 31 is connected to a water pipe 32, the water inlet end of the water pipe 32 is bolted to a pump 33, the pump 33 is bolted to the top of the box 1, and the top of the box 1 is bolted to a motor 34.

[0045] Furthermore, in order to rotate the stop door 4, specifically, a magnet 41 and a rotating sleeve 43 are welded to the side wall of the housing 1, a metal block 42 and a mating sleeve 44 are welded to the inner wall of the stop door 4, the rotating sleeve 43 and the mating sleeve 44 are rotatably connected, and a handle d45 is welded to the outer wall of the stop door 4.

[0046] It is worth noting that, specifically, for the purpose of exhaust, the exhaust device 5 includes: an exhaust port 51 is opened at the bottom end of the side wall of the housing 1; The exhaust vent 52 is located at the bottom of the inner wall of the housing 1; Filter plate 53 is welded to the inner wall of exhaust port 51; The electric push rod a54 is bolted to the inner wall of the exhaust groove 52, and the telescopic end of the electric push rod a54 is bolted to a baffle 55.

[0047] Finally, in order to control each component, specifically, the control mechanism 300 includes: multiple ambient temperature and humidity sensors 301 bolted to the top of the support frame 2 and the base plate 101; Multiple matrix volumetric water content sensors 302 are inserted inside the matrix 3; Multiple matrix EC value sensors 303 are inserted inside the matrix 3; Multiple integrated light quality and light cycle sensors are bolted to the bottom of the LED lamp holder 22; Multiple plant height monitoring sensors are bolted to the bottom of the LED light fixture 22 using 305 bolts. The control box 306 is bolted to the side wall of the box 1. The signal input terminal of the control box 306 is connected to the signal output terminals of multiple environmental temperature and humidity sensors 301, substrate volumetric water content sensor 302, substrate EC value sensor 303, light quality and photoperiod integrated sensor 304, and plant height monitoring sensor 305. The signal output terminal of the control box 306 is connected to the signal input terminals of electric push rod a54, electric push rod b21, LED lamp holder 22, and pump 33.

[0048] Example 1, combined with Figures 2-9 In this embodiment, an intelligent garden cultivation box is provided: First, the user sets the information of the edible chrysanthemum variety to be cultivated and the expected quality target through a mobile APP connected to the control box 306. The system then automatically selects the pre-stored "flowering priority", "flavor priority" or "nutrition priority" control mode accordingly. Example 2, combined with Figures 2-9 This embodiment of an intelligent garden cultivation box includes the following: During cultivation, various sensors inside the box 1 continuously collect data; a light quality and photoperiod integrated sensor 304 monitors in real time the light intensity, spectral composition (especially the proportion of blue light, ultraviolet light UV-A and UV-B), and cumulative light exposure time received by each layer of plants; an environmental temperature and humidity sensor 301 monitors the air temperature and humidity of each layer; a substrate volumetric water content sensor 302 and a substrate EC value sensor 303 monitor the water and nutrient status of the root zone, respectively; and a plant height monitoring sensor 305 continuously tracks changes in plant height. Example 3, combined with Figures 2-9 In this embodiment, an intelligent garden cultivation box is provided: the intelligent control box 306 serves as the core of the system, receiving and analyzing all sensor data; it first automatically determines the current growth stage of the edible chrysanthemum based on the accumulated effective photoperiod data, such as the vegetative growth period, flower bud differentiation period, flower bud formation period, petal color development period, or pre-harvest period; Example 4, combined with Figures 2-9 In this embodiment, an intelligent garden cultivation box is provided: Subsequently, the control box 306 calls the pre-stored control model and sends instructions to the actuator according to the mode selected by the user and the identified growth stage. If the flower viewing priority mode is selected and the petals are in the color-developing period, the control box 306 will activate the light quality control program, instructing the LED light stand 22 to supplement the daily basic light with a specific ratio of blue light and ultraviolet UV-A light to significantly stimulate anthocyanin synthesis and make the petals more vibrant. If the flavor-priority mode is in effect and the buds are forming in the middle to late stages, the control box 306 will initiate a mild water stress program, instructing the pump 33 to reduce the water supply through the seepage pipe 31, reducing the volumetric water content of the substrate 3 to the target range, thereby inducing the plant to produce secondary metabolites, enhancing the sweet flavor and reducing the bitterness. If the nutrient priority mode is in place and it is in the early stage of harvest, the control box 306 will start the compound stress induction program, simultaneously instruct the LED lamp holder 22 to supplement low dose of ultraviolet light UV-B, and instruct the pump 33 to control the seepage pipe 31 to implement mild water stress, so as to synergistically and significantly increase the content of antioxidant substances such as anthocyanins and total phenols in the petals. Example 5, combined with Figures 2-9 This embodiment provides an intelligent garden cultivation box: users can visually monitor the moisture content of the substrate 3 through the observation window 208; when it is necessary to manage the plants or replace the substrate 3, the loading box 203 can be easily pulled out of the box along the guide rail 201 using the handle c205; when the environmental monitoring indicates that ventilation is required, the control box 306 can instruct the electric push rod a54 to move, causing the baffle 55 to open or close for ventilation. Example 6, combined with Figures 2-9 This embodiment of an intelligent garden cultivation box allows users to provide subjective flavor feedback via an app after harvesting. The system can then learn and optimize preset model parameters based on historical data and evaluation results, making the next cultivation more in line with the user's personalized preferences.

[0049] Combination Figures 2-9 The specific usage process of this embodiment of an intelligent garden cultivation box is as follows: 1: Depending on the actual use, the user can simultaneously rotate the handle a105 located at the top and the handle b114 located on the side of the support frame 2; handle a105 drives the screw a103 to rotate, and handle b114 drives the screw b112 to rotate. At this time, the two support frames 2 and the bottom plate 101 at the top will rise and fall synchronously as a whole, thereby quickly changing the internal space layout of the entire cultivation box. 2: If only the spacing between the middle and bottom support frames 2 needs to be adjusted, the user can turn the handle b114 separately; since the screw b112 is designed with external threads b113 in opposite directions, when rotated, it will drive the two support frames 2 to move towards or away from each other, thereby expanding or shrinking the spacing between layers, while the top bottom plate 101 remains stationary; this design has self-locking properties, which can effectively prevent misoperation. 3: If only the height of the bottom layer needs to be changed, the user can turn the handle a105 alone; at this time, the rotation of the screw a103 will drive the bottom support frame 2 to rise and fall independently, while the upper structure will move as a whole under the linkage of the screw b112. 4: Open the door 4 and grasp the handle c205 on the side of the target loading box 203; gently pull it outward in a straight line; at this time, the ball 204 at the bottom of the loading box 203 will roll smoothly in the groove 202 of the guide rail 201, greatly reducing friction, so that even the loading box 203 filled with moist substrate 3 can be easily and smoothly pulled out of the box 1; after the loading box 203 is completely pulled out, the user can comfortably carry out various gardening management outside the box; after the operation is completed, push the loading box 203 back to its original position along the guide rail 201 again by using the handle c205, and close the door 4.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
