[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] The following description, in conjunction with the accompanying drawings, describes the plant light and temperature regulation method, apparatus, equipment, and storage medium of the present invention.

[0049] Figure 1 This is a schematic flowchart of the plant light and temperature regulation method provided by the present invention, as shown below. Figure 1 As shown, the method includes steps 101 to 104; wherein:

[0050] Step 101: Obtain basic information about the target plant whose light and temperature need to be regulated; wherein, the basic information includes at least one of the following: plant type and plant growth period;

[0051] Step 102: Obtain the target light-temperature coupling curve corresponding to the basic information from the pre-set plant growth light-temperature coupling curve;

[0052] Step 103: Based on the target light-temperature coupling curve, determine the target light control parameters and target temperature control parameters corresponding to the pre-set target demand indicators when the requirements are met;

[0053] Step 104: Based on the target light control parameters and the target temperature control parameters, perform light and temperature regulation on the target plant.

[0054] Specifically, in related technologies, light and temperature for plants are typically controlled to a fixed value, resulting in high costs for supplemental lighting and heating. These costs mainly include hardware investment and energy costs. Generally, for different plants and different growth stages, parameters such as photosynthetic intensity show a certain curvilinear relationship with temperature and light. This means that light and temperature have a certain coupling relationship. If, under a certain light level, the temperature exceeds a certain value, further increasing the temperature will not significantly increase the plant's photosynthesis and may even lead to a decrease in photosynthesis, which will cause a sharp increase in heating costs. Similarly, under a certain temperature level, when the light parameter exceeds a certain value, further increasing the light parameter will no longer significantly increase the plant's photosynthesis, and further increasing the light parameter value will lead to increased energy costs.

[0055] To address the aforementioned problems, this invention proposes a light and temperature regulation method for plants that can both meet the optimal light and temperature conditions for plant growth and minimize the cost of light and temperature regulation.

[0056] In this embodiment of the invention, the basic information of the target plant whose light and temperature are to be regulated is first obtained, so as to obtain the target light and temperature coupling curve corresponding to the basic information of the target plant from the plant growth light and temperature coupling curve. For example, the target light and temperature coupling curve corresponding to the plant type and growth stage of the target plant is obtained. Then, based on the target light and temperature coupling curve, the target light control parameters and target temperature control parameters corresponding to the target demand index when the requirements are met can be determined, and the light and temperature of the target plant can be regulated based on the target light control parameters and target temperature control parameters.

[0057] Optionally, the target requirement indicators may include target light intensity, target supplemental lighting intensity, or photosynthetic capacity.

[0058] In the plant photothermal regulation method provided in this embodiment of the invention, compared with the related technology that regulates the light and temperature of plants to a certain fixed value, this embodiment of the invention considers the influence of basic information such as plant type and plant growth period on plant photothermal regulation, so that the plant photothermal regulation is adapted to the plant growth process, thereby accurately controlling the plant supplemental lighting and heating, avoiding the situation of excessive supplemental lighting and heating with insignificant effect on plant growth, and effectively reducing the cost of supplemental lighting and heating while ensuring that the target requirements are met.

[0059] Optionally, the method of implementing light and temperature regulation of the target plant based on the target light control parameters and the target temperature control parameters may include:

[0060] Based on the target light control parameters and the target temperature control parameters, the target plant is subjected to light and temperature regulation through a pre-set mobile supplemental lighting and heating device.

[0061] Specifically, a mobile supplemental lighting and heating device refers to a movable supplemental lighting and heating device, which may include modules such as supplemental lights and heating tubes.

[0062] Compared to the use of fixed devices to regulate the light and temperature of plants in related technologies, the embodiments of the present invention use a movable supplemental lighting and heating device to regulate the light and temperature of the target plants. This can reduce the density of supplemental lighting and heating devices, increase the frequency of use of supplemental lighting and heating devices, reduce the layout and investment costs of hardware devices, and at the same time greatly reduce the shading effect of the hardware device layout itself on the plants.

[0063] Optionally, before adjusting the light and temperature of the target plant using a pre-set mobile supplemental lighting and heating device based on the target light control parameters and the target temperature control parameters, the number of mobile supplemental lighting and heating devices can be determined first.

[0064] The minimum number of mobile supplementary lighting and heating devices, X, is calculated using formula (1):

[0065] X=(Y*Z) / 24 (1)

[0066] Where Y represents the number of supplemental lighting devices under full deployment conditions, and Z represents the target supplemental lighting time for the target plant within 24 hours;

[0067] Based on the minimum number X, the target number of the mobile supplementary lighting and heating device is determined.

[0068] Specifically, by utilizing the supplemental lighting and heating cycles of the target plant and setting up mobile supplemental lighting and heating systems, the density of plant supplemental lighting and heating devices can be reduced.

[0069] Optionally, technicians can set the target number of mobile supplementary lighting and heating devices between X and Y according to the actual situation. It should be noted that the specific setting of the target number needs to be obtained by combining the setting position and movement strategy of the mobile supplementary lighting and heating devices.

[0070] For example, if the supplemental lighting and heating device is fixed and does not move, 1,000 supplemental lights are needed per acre. If a mobile supplemental lighting and heating device is used for mobile supplemental lighting, only 200 supplemental lights may be needed. The above formula calculates the X value, and it is necessary to ensure that the light time and intensity received by the plants under this X value are consistent with the Y value.

[0071] Optionally, the mobile supplemental lighting and heating device may include a supplemental lighting module and a heating module.

[0072] If the current temperature of the target plant is detected to be lower than the preset start-up temperature value of the heating module, the heating module is activated.

[0073] If the current temperature of the target plant is detected to be higher than the preset activation temperature value of the supplemental lighting module, the supplemental lighting module is activated.

[0074] Specifically, if the current temperature of the target plant is detected to be lower than the preset activation temperature of the heating module, the heating module can be activated to provide heating; if the current temperature of the target plant is detected to be higher than the preset activation temperature of the supplemental lighting module, the supplemental lighting module can be activated to provide supplemental lighting.

[0075] It should be noted that when the current temperature of the target plant is detected to be higher than the preset activation temperature of the supplemental lighting module, the supplemental lighting module is activated in order to further improve productivity. This can be understood as follows: at the current temperature, when the light intensity is increased by the same proportion, parameters such as the photosynthetic rate increase significantly, which can effectively improve the productivity of the target plant.

[0076] It should also be noted that supplemental lighting and heating are both intended to enhance the photosynthesis of plants, assimilate products, and thus increase yield. The photosynthetic rate is related to both light and temperature. Within a certain range, increasing temperature can increase the photosynthetic rate, and increasing light can also increase the photosynthetic rate.

[0077] Optionally, the heating module may be, for example, a hot water or hot air heating pipe, or an electric heating wire circuit; the supplementary lighting module may be, for example, a supplementary light.

[0078] Optionally, if the current light intensity of the target plant is detected to be lower than the preset light intensity value for activating the supplementary lighting module, the supplementary lighting module is activated;

[0079] If the current light intensity of the target plant is detected to be higher than the preset light intensity value for the heating module to start, the heating module is activated.

[0080] Specifically, if the current light intensity of the target plant is detected to be lower than the preset light intensity value for the supplementary lighting module, the supplementary lighting module can be activated to provide supplementary lighting; if the current light intensity of the target plant is detected to be higher than the preset light intensity value for the heating module, the heating module can be activated to provide heating.

[0081] It should be noted that if the current light intensity of the target plant is detected to be higher than the preset light intensity value for the heating module to start, the heating module will be activated in order to further increase production capacity.

[0082] Optionally, the mobile supplementary lighting and heating device is equipped with a blowing circulation device, which is used to blow air according to preset blowing parameters.

[0083] Specifically, the mobile supplemental lighting and heating device can be equipped with a blowing and circulation device. The blowing and circulation device can remove dust from the leaf surface and increase transpiration and the uniformity of air temperature and carbon dioxide concentration around the leaves, thereby greatly improving the effect of supplemental lighting and heating.

[0084] Optionally, a blower can be installed on both sides of the supplemental light of the mobile supplemental lighting and heating device, with the fan of the blower pointing towards the plant.

[0085] Optionally, before obtaining the target light-temperature coupling curve corresponding to the basic information from the pre-set plant growth light-temperature coupling curve, the plant growth light-temperature coupling curve can be generated first through the following steps:

[0086] Within a pre-set temperature parameter range, N constant temperature parameter values ​​are selected sequentially according to the gradient, where N is an integer greater than 1;

[0087] Obtain the curve of the target plant's target requirement index as a function of light parameter values ​​under the N constant temperature parameter values, and use it as the first curve.

[0088] Within a pre-set range of optical parameters, M constant optical parameter values ​​are selected sequentially according to the gradient, where M is an integer greater than 1;

[0089] Obtain the curve of the target plant's target requirement index as a function of temperature parameter values ​​under the M constant light parameter values, and use it as the second variation curve;

[0090] The light-temperature coupling curve for plant growth is generated based on the first change curve and / or the second change curve.

[0091] Specifically, a range of temperature or light parameter values ​​can be set, and then a constant temperature or light parameter value can be selected within the range according to the gradient. The change curve of the plant growth target requirement index under the change of the other parameter value can be measured. The target requirement index is, for example, the amount of photosynthesis.

[0092] Then, within the range, select different constant temperature values ​​or light parameter values ​​according to the gradient, and measure the change curve of the plant growth target requirement index under the change of another parameter value, and so on;

[0093] For each curve, the temperature and light parameter values ​​corresponding to the optimal values ​​of the plant growth target requirements are obtained. The temperature and light parameter values ​​of this data set are fitted into a curve, which is used as the light-temperature coupling curve for plant growth.

[0094] Optionally, different light-temperature coupling curves for plant growth can be obtained from experiments based on different species and different growth stages of the target plant.

[0095] The following example illustrates the light and temperature regulation method for plants provided in the embodiments of the present invention.

[0096] I. The plant light and temperature regulation method of the present invention can be implemented by the following parts:

[0097] 1. Mobile supplemental lighting and heating device: Arc-shaped and planar mobile supplemental lighting and heating devices can be installed above the elevated plant cultivation rack and the planar plant cultivation rack, respectively. The supplemental lighting device is generally a supplemental light lamp, and the heating device is generally a hot water or hot air heating pipe, or an electric heating wire circuit. The mobile supplemental lighting and heating device can be controlled by a control system to control its moving direction and moving speed. The supplemental light lamp can move horizontally and vertically.

[0098] 2. Arrangement of Supplemental Lights and Heating Devices: The placement of supplemental lights can be calculated based on target requirements using the formula X1 = (Y1 * Z1) / 24. The minimum number of supplemental lights (X1) is calculated, where Y1 represents the number of lights at full capacity, and Z1 represents the target supplemental lighting time for the target plant within 24 hours. Z1 is greater than 0 and less than 24. Heating devices can be fixedly placed on top of the plant or within the root cultivation medium, or they can be moved along with the supplemental lights as needed.

[0099] 3. Anti-interference air circulation device: Circulating fans are added at intervals on both sides of the supplemental light. When the plant supplemental light reaches the top of the plant, the air circulation device can remove suspended dust from the leaves, increase leaf transpiration, and at the same time make the air temperature between the leaves uniform. This can reduce the impact of dust and low transpiration on the achievement of the goal of increasing photosynthesis by supplemental light, increase the heating effect, and also achieve the purpose of increasing the leaves to better improve photosynthesis.

[0100] 4. Plant supplemental lighting and heating linkage control: By setting temperature and light parameter gradient values ​​for different plants, the supplemental lighting and temperature control parameter curves of the plants are obtained. As a decision model for the linkage control of plant light and temperature, the model can be implanted into the control system. In production, arbitrary parameter values ​​for supplemental lighting and temperature control can be set to achieve the purpose of linkage control of plant light and temperature.

[0101] two, Figure 2 This is a schematic diagram of the plant light and root temperature linkage regulation system provided by the present invention, as shown below. Figure 2 As shown, supplemental lighting and temperature control devices can be placed on top of plants, between plants, or at the base of plants, depending on the needs.

[0102] Plant heating methods can generally be arranged in two ways depending on the needs: one is root heating, where the heating pipes are directly fixed inside the plant root cultivation medium. Figure 3 This is a side view (root heating) of the planar plant mobile supplemental lighting and heating device provided by the present invention, as shown. Figure 3 As shown, the planar plant mobile supplemental lighting and heating device includes: 1-substrate heating pipe, 2-cultivation system, 3-supplemental lighting system, 4-fan system, 5-longitudinal sliding mechanism, 6-supplemental lighting rod and 7-lateral sliding mechanism;

[0103] Secondly, it can be fixed in place or placed on top of the plants along with the supplemental lighting. Heating can be achieved using hot water pipes, hot air pipes, or electric heating wires. Figure 4 This is a side view (top heating) of the planar plant mobile supplemental lighting and heating device provided by the present invention, as shown. Figure 4As shown, the planar plant mobile supplemental lighting and heating device includes: 1-cultivation system, 2-suspended heating system, 3-heating system hanging mechanism, 4-horizontal sliding mechanism, 5-supplemental lighting hanging mechanism, 6-supplemental lighting longitudinal sliding mechanism, 7-supplemental lighting system, 8-fan system and 9-substrate heating pipeline;

[0104] For flat cultivation of plants, mobile supplemental lighting devices are generally designed in a planar form, with the lights typically positioned at least 20 centimeters above the plant's growing point. Figure 3 or Figure 4 As shown; for multi-layered elevated cultivation of plants, the grow lights are generally set in an arc shape along the outline of the plant support, and are also generally positioned at least 20 centimeters above the plant's growing point. Figure 5 This is a side view of the mobile supplemental lighting and heating device for elevated plants provided by the present invention, as shown in the figure. Figure 5 As shown, the elevated plant mobile supplemental lighting and heating device includes: 1-ring track support, 2-cultivation system, 3-supplemental lighting system and 4-longitudinal sliding mechanism.

[0105] The supplementary lighting device and the temperature control device are connected to the programmable controller, which is connected to the main power supply. The programmable controller can set the light density, light quality, supplementary lighting time, temperature setting, and temperature control time setting.

[0106] The programmable controller is connected to light and temperature sensors for monitoring plant light and temperature parameters.

[0107] The supplementary lighting device can be configured to have adjustable light quality and light density according to requirements;

[0108] The supplementary lighting device can also be set with a moving direction and a moving speed;

[0109] The temperature control device can be configured to both heat up and cool down as needed.

[0110] III. The plant photothermal regulation method of the present invention requires fitting a plant growth photothermal coupling curve:

[0111] First, set a range of temperature or light parameter values. Within the range, select a constant temperature or light parameter value according to a gradient. Measure the change curve of the plant growth target requirement index, such as the amount of photosynthesis, under the change of the other parameter value.

[0112] Then, within the range, select different constant temperature values ​​or light parameter values ​​according to the gradient, and measure the change curve of the plant growth target requirement index under the change of another parameter value, and so on;

[0113] For each curve, the temperature and light parameter values ​​corresponding to the optimal values ​​of the plant growth target requirements are obtained. The temperature and light parameter values ​​of this data set are fitted into a curve to serve as a regulatory strategy model for the linkage between light and temperature.

[0114] Different regulatory strategy models can be obtained from experiments based on different plant species and different growth stages;

[0115] The obtained control strategy model program is programmed into the control system controller, which can automatically adjust the light and temperature to the optimal combination value based on the sensor parameters.

[0116] IV. Example 1: Adjustable plant supplemental lighting and heating device and light-temperature linkage control method.

[0117] The device includes: a plant cultivation trough, plants, supplemental lighting, a flat movable device, a heating device, a blowing device, a light sensor, an air temperature sensor, and a control system.

[0118] The plants are planted in flat plant cultivation troughs. A flat movable device is fixed above the plants. A supplemental light, a heating element, and a blower are fixed on the movable device. The supplemental light is set more than 20 cm above the plants, the heating element is set on both sides of the supplemental light, and the blower is set diagonally behind or above the heating element.

[0119] The movable device allows the supplementary light, heating tube, and blower to move longitudinally, laterally, or cyclically, and the moving speed of the movable device is adjustable.

[0120] The light quality and formula of the fill light are adjustable, the temperature of the heating element is adjustable, and the airflow speed of the blower fan is adjustable.

[0121] Light and temperature sensors are installed above the plant. The sensors are connected to a programmable logic controller (PLC) control system, which is connected to a movable device, supplemental lighting, a fan, and a heating element.

[0122] Arrange the appropriate number of supplemental lights according to the different plant species, and set the light quality, light formula, supplemental lighting time, heating tube temperature, fan speed, and the moving speed of the supplemental lights and heating tubes.

[0123] When plants are being cultivated, a mobile device can be used to circulate and move the top of the plant to provide supplemental lighting. During supplemental lighting, heating pipes and air blowers can be used to clean the leaf surface and increase the temperature and air circulation around the leaves, thus better achieving the goal of increasing photosynthesis and yield.

[0124] The system can also be set to activate the blower and adjust the wind speed. When the blade surface or air temperature is higher than a certain value, the blower can be forcibly activated to reduce the blade temperature.

[0125] Optionally, the heating element activation temperature and supplemental lighting activation parameters for the plant can be set. The temperature parameter has two values: a heating element activation temperature (activating when the temperature is below this value) and a supplemental lighting activation temperature (activating when the temperature is above this value). The lighting parameter can also have two values: a supplemental lighting activation light intensity value (activating when the light intensity is below this value) and a heating element activation light intensity value (activating when the light intensity is above this value).

[0126] V. Comparative Example 1: This comparative example uses the same method as Example 1 above for plant cultivation and management, with strawberry plants as the object. The only difference is that no supplemental lighting and heating device or air blowing device is set up.

[0127] Comparative Example 2: This comparative example uses the same method as Example 1 above for plant cultivation and management, with strawberry plants as the object, and the light and temperature management system is the same, the only difference being that the supplemental lights and heating tubes are arranged and fixed in a fully fixed manner.

[0128] Comparative Example 3: This comparative example uses the same method as Example 1 above for plant cultivation and management, with strawberry plants as the object, and the light and temperature management system is the same, the only difference being that: no blower device or blower treatment is set up.

[0129] Experimental Example 1: This experimental example statistically analyzes the strawberry planting results of Example 1 and Comparative Examples 1-3 above. The planting area is 500 square meters, with a total of 20 rows, each row being 20 meters long, for a total of 4000 strawberry plants. The lamp tubes are 1 meter long, and the target supplemental lighting time is 4 hours / day. Specific results are shown in Table 1.

[0130] Table 1 Detailed Results

[0131]

[0132] As shown in Table 1, the number of lamps used in Example 1 is significantly less than that in Comparative Example 2, and the strawberry yield is significantly greater than that in Comparative Example 1 and Comparative Example 3, and almost the same as that in Comparative Example 2. This is more conducive to reducing investment costs and ensuring yield.

[0133] VI. Example 2: Adjustable plant supplemental lighting and heating device and light-temperature linkage control method.

[0134] The device includes: a plant cultivation trough, plants, supplemental lighting, an arc-shaped movable device, a heating device, a blower device, a light sensor, an air temperature sensor, a root temperature sensor, and a control system.

[0135] The plants are grown in elevated cultivation troughs. A movable, arc-shaped device is fixed above the plants. The movable, arc-shaped device is set along the perimeter of the elevated structure. A supplemental light and a fan are fixed on the movable, arc-shaped device. The supplemental light is set at least 20 centimeters away from the plant's growth point. The heating element is placed in the cultivation medium of the elevated plant cultivation trough. The fan is set on both sides of the supplemental light, with the fan direction facing the plant.

[0136] The curved movable device allows the fill light and blower to move longitudinally, laterally, or cyclically, and the moving speed of the curved movable device is adjustable.

[0137] The light quality and formula of the fill light are adjustable, the temperature of the heating element is adjustable, and the airflow speed of the blower fan is adjustable.

[0138] Light and temperature sensors are installed above the plants. The sensors are connected to a PLC control system, which in turn is connected to a movable device, a supplemental light, a fan, and a heating element.

[0139] Fitting the light-temperature coupling curve for plant growth: By setting a range of temperature or light parameter values, a constant temperature or light parameter value is selected within the range according to a gradient, and the change curve of the plant growth target requirement index, such as the amount of photosynthesis, is measured under the change of the other parameter value;

[0140] Among them, different constant temperature values ​​or light parameter values ​​are selected according to the gradient within the range, and the change curve of the plant growth target requirement index is measured under the change of another parameter value, and so on.

[0141] The temperature and light parameter values ​​corresponding to the optimal values ​​of the plant growth target demand index obtained from each curve are fitted into a curve, which serves as a regulatory strategy model for the linkage between light and temperature.

[0142] Different regulatory strategy models can be obtained from experiments based on different plant species and different growth stages;

[0143] The obtained control strategy model program is programmed into the control system controller, which can automatically adjust the light and temperature to the optimal combination value based on the sensor parameters.

[0144] Arrange the appropriate number of grow lights according to different plant species, and set the light quality, light formula, grow light time, fan speed, heating element temperature, and grow light moving speed.

[0145] When the plant is being cultivated, the mobile device can be used to circulate and move the top of the plant to provide supplemental lighting. During supplemental lighting, the air blowing device can clean the leaf surface and increase air circulation around the leaves, thus better achieving the goal of increasing photosynthesis and yield.

[0146] Optionally, the heating element activation of the plant can be controlled by setting the substrate temperature;

[0147] Specifically, the lighting parameters can be adjusted based on air temperature and supplemental lighting. The air temperature is set to the supplemental lighting's activation temperature; when the temperature exceeds this value, the supplemental lighting will activate. The fan activation and wind speed can also be set; when the leaf surface or air temperature exceeds a certain value, the fan can be forcibly activated to lower the leaf temperature.

[0148] Among them, the lighting parameter value can be set to the light intensity value of the fill light. When the light intensity is lower than this value, the fill light will be activated.

[0149] In the embodiments of the present invention, at least the following beneficial effects exist:

[0150] 1) Through calculation formulas and mobile devices, the minimum settings for plant supplemental lighting and heating devices can be achieved, greatly reducing hardware investment costs;

[0151] 2) The plant grow lights are equipped with a blower circulation device on the side to remove dust from the leaf surface and increase transpiration and the uniformity of air temperature and carbon dioxide concentration around the leaves, which greatly improves the effect of supplemental lighting and heating.

[0152] 3) By using a light-temperature linkage control strategy, the supplemental lighting and heating of plants can be precisely controlled by fitting the plant supplemental lighting and heating curve, which greatly reduces ineffective supplemental lighting and heating.

[0153] 4) The connection structure is simple and the control is simple. It can realize the linkage regulation of light and temperature parameters of plant growth environment. At the same time, it can be regulated according to the optimal light and temperature fitting curve of different crops and growth stages, so as to achieve automated light and temperature regulation and realize efficient and low-cost light and temperature management of plant production.
