Description

Technical Field

[0001] The present invention belongs to the technical field of plant cross - latitude transplantation. Specifically, it relates to a temperature control method, medium and system for plant cross - latitude transplantation. Background Art

[0002] In modern agricultural production and the process of plant introduction, plant cross - latitude transplantation is a common and important technical means, aiming to transfer plants from one growth environment to another environment with different climate conditions. This cross - regional transplantation activity is of great significance for improving crop yields, improving varieties, protecting biodiversity, etc. However, due to the obvious differences in climate conditions between different regions, especially the differences in temperature conditions, plants often suffer from varying degrees of stress during the transplantation process, which may lead to transplant failure or poor growth of plants. Existing plant transplantation technologies mainly focus on the adaptive adjustment of growth conditions such as soil, water, and light before and after transplantation, while relatively less research has been done on the problem of temperature adaptation during plant transplantation. In actual operation, when plants are directly transplanted from the original growth place to the destination, they often suffer from a chaotic growth cycle, damaged physiological functions, or even death due to sudden changes in temperature conditions. This is because the growth and development of plants are closely related to the temperature conditions of their growth environment, and sudden changes in temperature will have an adverse impact on the normal physiological activities of plants, such as affecting photosynthesis, respiration, and the absorption and transport of nutrients.

[0003] In the prior art, although there are methods using equipment such as greenhouses and incubators to control the temperature of plants, these methods often lack pertinence because they do not design precise temperature transition schemes based on the temperature differences between the original growth place and the destination, and the temperature control often uses a constant temperature or a simple temperature change mode, resulting in a low transplantation success rate. Summary of the Invention

[0004] In view of this, the present invention provides a temperature control method, medium and system for plant cross - latitude transplantation, which can solve the technical problems in the prior art that during the process of plant cross - latitude transplantation, no precise temperature transition scheme is designed based on the temperature differences between the original growth place and the destination, and the temperature control often uses a constant temperature or a simple temperature change mode, resulting in a low transplantation success rate.

[0005] The present invention is implemented as follows:

[0006] The first aspect of the present invention provides a temperature control method for plant cross - latitude transplantation, which includes the following steps:

[0007] S10. Obtain the temperature data of the original growth place and the destination, including the temperature curve for each day of the whole year;

[0008] S20. Determine the starting temperature curve of the temperature transition period required for transplantation based on the temperature data of the original growth location and the destination. The temperature transition period is the process of gradually changing the temperature from the original growth location to the destination temperature;

[0009] S30. Establish a temperature transition period model, calculate the length of the transition period, and calculate the specific temperature curve for each day during the temperature transition period, which is recorded as the daily temperature curve of the transition period. The daily temperature curves for each day during the temperature transition period are synthesized into a set of daily temperature curves;

[0010] S40. In the set of daily temperature curves, calculate the similarity between two adjacent daily temperature curves, and take the day corresponding to the left curve of the daily temperature curve with the lowest similarity as the transplantation day;

[0011] S50. According to the daily temperature curves before the transplantation day in the set of daily temperature curves, control the temperature control equipment at the original growth location to conduct artificial temperature control cultivation on the plants;

[0012] S60. According to the daily temperature curve of the transplantation day, control the temperature control equipment in the transportation vehicle to conduct artificial temperature control cultivation on the plants;

[0013] S70. According to the daily temperature curves after the transplantation day, control the temperature control equipment at the destination to conduct artificial temperature control cultivation on the plants.

[0014] Based on the above technical solution, a method for controlling the temperature of cross-latitude transplantation of plants according to the present invention can be further improved as follows:

[0015] Among them, the steps of obtaining the temperature data of the original growth location and the destination, including the temperature curve for each day of the whole year, specifically include: obtaining the historical temperature data of the original growth location and the destination through meteorological stations or climate databases, and extracting the temperature curve for each day of the whole year.

[0016] Among them, the steps of determining the starting temperature curve of the temperature transition period required for transplantation based on the temperature data of the original growth location and the destination specifically include:

[0017] Cluster the temperature curves for each day of the whole year at the original growth location to obtain the average daily temperature curve of the original growth location;

[0018] Obtain the similarity between the actual daily temperature curve of the plant at the original growth location and the average daily temperature curve of the original growth location, and take the actual daily temperature curve with the maximum similarity as the starting temperature curve of the transition period.

[0019] Furthermore, the steps of establishing a temperature transition period model, calculating the length of the transition period, and calculating the specific temperature curve for each day during the temperature transition period, which is recorded as the daily temperature curve of the transition period, specifically include:

[0020] According to the obtained starting temperature curve of the transition period and the temperature data of the original growth location and the destination, a temperature transition period model is constructed to simulate the smooth transition of temperature from the original growth location to the destination;

[0021] Define the length of the transition period through the temperature transition period model, and calculate the expected temperature for each day during this process to form a daily temperature curve for the transition period.

[0022] Among them, the step of calculating the similarity between two adjacent daily temperature curves in the set of daily temperature curves and taking the day corresponding to the left curve of the daily temperature curve with the lowest similarity as the transplantation day specifically includes:

[0023] For each day in the established temperature transition period model, calculate the temperature distribution characteristics of the daily temperature curve;

[0024] Use the similarity calculation formula to evaluate the similarity between two adjacent daily temperature curves;

[0025] Sort the similarities of all adjacent daily temperature curves and find the point with the lowest similarity;

[0026] Take the day corresponding to the left curve of the lowest similarity point as the optimal transplantation day.

[0027] Furthermore, in the step of obtaining the similarity between the actual daily temperature curve of the plant at the original growth location and the average daily temperature curve of the original growth location, the calculation method of the similarity is the cosine similarity.

[0028] Furthermore, for the method of the temperature transition period model, the linear interpolation method is adopted.

[0029] Among them, in the step of using the similarity calculation formula to evaluate the similarity between two adjacent daily temperature curves, the formula for calculating the similarity adopts the cosine similarity formula.

[0030] The second aspect of the present invention provides a computer-readable storage medium, wherein program instructions are stored in the computer-readable storage medium, and when the program instructions run, they are used to execute the above-mentioned temperature control method for plant cross-latitude transplantation.

[0031] The third aspect of the present invention provides a temperature control system for plant cross-latitude transplantation, which includes the above-mentioned computer-readable storage medium.

[0032] Compared with the prior art, the beneficial effects of a temperature control method, medium and system for cross-latitude transplantation of plants provided by the present invention are as follows: A temperature transition model is established to calculate the length of the transition period and the transplantation date, and a temperature curve for each day can be established to form an accurate temperature transition plan, solving the technical problem in the prior art that during the cross-latitude transplantation of plants, an accurate temperature transition plan is not designed according to the temperature difference between the original growth place and the destination, and the temperature control often adopts a constant temperature or a simple temperature change mode, resulting in a low transplantation success rate.

[0042] S20. Determine the starting temperature curve of the temperature transition period required for transplantation according to the temperature data of the original growth location and the destination.

[0047] S70. According to the daily temperature curves after the transplantation day, control the temperature control equipment at the destination and conduct artificial temperature control cultivation on the plants.

[0048] The specific implementation manners of the above steps are described in detail as follows:

[0049] Specific implementation manner of step S10:

[0050] The purpose of implementing step S10 is to collect historical temperature data of the original growth place and the destination, providing basic information for the determination of the temperature transition period and the establishment of the model later. This step can be achieved through the following sub-steps:

[0051] First, determine the data source. Select a suitable meteorological data provider or platform, which can usually provide accurate historical temperature data.

[0052] Next, collect data. Call the API of the data provider or download the temperature curve data of each day of the whole year at the original growth place and the destination through other means, including the maximum temperature, the minimum temperature, and the average temperature, etc.

[0053] Then, preprocess the data. Clean the obtained temperature data, including removing outliers, filling missing values, data formatting, etc., to ensure the data quality.

[0054] Finally, store the data. Store the preprocessed temperature data in a database or other suitable data storage system for convenient calling and analysis in subsequent steps.

[0055] Specific implementation manner of step S20:

[0056] Determine the starting temperature curve of the temperature transition period required for transplantation according to the temperature data of the original growth place and the destination. The temperature transition period is the process of the gradual change of the temperature from the original growth place to the destination.

[0057] Specific implementation manner of step S30:

[0058] First, format the obtained temperature data of each day of the whole year at the original growth place and the destination;

[0059] Use statistical analysis methods to evaluate the periodicity and change trend of the temperature data.

[0060] Determine the key feature points of the temperature data of the original growth place and the destination;

[0061] Use interpolation or regression analysis methods to construct a temperature transition period model for simulating the smooth transition of the temperature from the original growth place to the destination;

[0062] Define the length of the transition period through the temperature transition period model and calculate the expected temperature of each day in this process to form the daily temperature curve of the transition period.

[0063] Specific implementation manner of step S40:

[0064] For each day in the established temperature transition period model, calculate the temperature distribution characteristics of the daily temperature curve;

[0065] Use the similarity calculation formula to evaluate the similarity of adjacent daily temperature curves;

[0066] Sort the similarities of all adjacent daily temperature curves and find the point with the lowest similarity;

[0067] Take the day corresponding to the curve on the left side of the lowest similarity point as the optimal transplantation day.

[0068] Specific implementation of step S50:

[0069] Step S50 involves, before the transplantation day, using the temperature control equipment in the original growth location to conduct artificial temperature-controlled cultivation of the plant. Implementing this step requires the following sub-steps:

[0070] According to the set of daily temperature curves, extract the daily temperature curve for each day before the transplantation day.

[0071] Set the parameters of the temperature control equipment to simulate the daily temperature curve for each day.

[0072] Monitor the growth status of the plant and adjust the settings of the temperature control equipment as needed to ensure that the plant grows in a suitable temperature environment.

[0073] Repeat this process until the transplantation day is reached to ensure that the plant gradually adapts to the temperature conditions at the destination.

[0074] The key factors to be considered in this step include temperature control accuracy, the adaptability of the plant, and possible environmental changes.

[0075] Specific implementation of step S60:

[0076] Step S60 focuses on how to control the temperature control equipment in the transportation vehicle to maintain the optimal growth state of the plant on the transplantation day. Implementing this step requires the following sub-steps:

[0077] Determine the daily temperature curve for the transplantation day and set the parameters of the temperature control equipment in the transportation vehicle to simulate this curve.

[0078] Monitor the status of the plant during transportation to ensure it is in a stable temperature environment.

[0079] According to the real-time monitoring data, timely adjust the settings of the temperature control equipment to cope with possible temperature fluctuations.

[0080] Ensure that the plant is in good growth condition at the end of transportation to provide guarantee for its adaptation after arriving at the destination.

[0081] The key factors to be considered in this step include temperature stability during transportation, the stress response of plants, and the reliability of equipment.

[0082] Specific implementation of step S70:

[0083] Step S70 involves how to use the temperature control equipment at the destination to artificially regulate the temperature cultivation of plants after the transplantation date. The implementation of this step requires the following sub-steps:

[0084] Extract the daily temperature curve after the transplantation date and set the parameters of the destination temperature control equipment.

[0085] Monitor the adaptation of plants in the new environment and adjust the settings of the temperature control equipment according to the growth conditions of the plants.

[0086] Gradually reduce the artificial temperature control intervention to allow the plants to adapt to the natural environmental conditions.

[0087] Record the process of plants adapting to the new environment for future improvement of temperature control strategies.

[0088] The key factors to be considered in this step include the variability of the destination climate, the speed at which plants adapt to the new environment, and the feasibility of long-term temperature control management.

[0089] The following is a specific embodiment of step S30 and step S40:

[0090] Step S30: Establish a temperature transition period model

[0091] In step S30, our goal is to establish a mathematical model for calculating the length of the temperature transition period for plants transplanted from the original growth location to the destination and obtaining the specific temperature curve for each day during the transition period.

[0092] Variable definitions:

[0093] T o (d): The temperature curve function of the original growth location on the d-th day.

[0094] T d (d): The temperature curve function of the destination on the d-th day.

[0095] D trans : The length of the temperature transition period, expressed in days.

[0096] T trans (d,t): The daily temperature curve function during the transition period at the d-th day and time t.

[0097] ΔT(d): The function of the temperature difference between the original growth location and the destination on the d-th day.

[0098] Process description:

[0099] Calculate the temperature difference between the original growth location and the destination. We define the temperature difference function ΔT(d) = T o (d) - Td ( d), which is used to represent the temperature difference between the original growth location and the destination on the d-th day.

[0100] By analyzing ΔT(d), determine the temperature transition period D trans . The transition period should be a time period during which the plant can gradually adapt to the temperature conditions of the destination. We can determine D by observing the change trend of ΔT(d) over time trans .

[0101] Establish a temperature transition period model T trans (d, t), which is used to calculate the specific temperature curve for each day during the transition period. This can be achieved through interpolation or regression analysis, such as using linear interpolation or polynomial interpolation methods.

[0102]

[0103] The above formula indicates that at the time point t on the d-th day, the temperature during the transition period is the weighted average of the temperature at the original growth location and the destination temperature. As time goes by, d increases from 0 to D trans , indicating that the plant gradually adapts to the temperature of the destination.

[0104] Calculate D trans For each day within D, calculate the daily temperature curve T trans (d, t), and synthesize them into a set of daily temperature curves.

[0105] Step S40: Calculate the similarity of the daily temperature curves

[0106] In step S40, we need to calculate the similarity between the daily temperature curves of adjacent days, and take the day corresponding to the left curve of the daily temperature curve with the lowest similarity as the transplantation day.

[0107] Variable definition:

[0108] Sim(d): The similarity function between the daily temperature curves of the d-th day and the (d + 1)-th day.

[0109] d opt : The day corresponding to the left curve of the daily temperature curve with the lowest similarity, that is, the transplantation day.

[0110] Process description:

[0111] Define a similarity measurement function Sim(d) to calculate the similarity between the daily temperature curves of adjacent days. The similarity can be calculated by various methods, such as Euclidean distance, Pearson correlation coefficient, or cosine similarity, etc.

[0112]

[0113] The above formula is a similarity calculation method, where the numerator represents the integral of the absolute difference between the daily temperature curves on the d-th day and the (d + 1)-th day, and the denominator represents the integral of the maximum absolute value in the two-day temperature curves. The lower the similarity, the greater the difference between the daily temperature curves of the two days.

[0114] Traverse all daily temperature curves, calculate the similarity Sim(d) between adjacent two days, and find the pair of daily temperature curves with the lowest similarity.

[0115] Determine the transplantation day d opt , that is, the day corresponding to the left curve of the daily temperature curve with the lowest similarity.

[0116] Use the daily temperature curve with the lowest similarity as the basis for the transplantation day.

[0117] Through the above steps, we can accurately calculate the optimal time point for plant transplantation and the ideal temperature curve for each day during the transplantation process, so as to provide the most suitable temperature conditions for the plants and ensure that the plants can successfully adapt to the new environment.

[0118] Specifically, the principle of the present invention is as follows:

[0119] 1. Temperature adaptability principle: Plants have a certain adaptability when facing environmental temperature changes. By setting the temperature transition period, the present invention simulates the process of plants naturally adapting to the environment, enabling plants to gradually adapt to the temperature conditions at the destination.

[0120] 2. Mathematical modeling principle: The present invention establishes a temperature transition period model and uses mathematical methods to analyze the temperature data of the original growth place and the destination, calculates the appropriate temperature transition period and the specific daily temperature curve, and realizes the scientific planning of the temperature control process.

[0121] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
