[0002] With the improvement of agricultural planting level, grafting technology has been widely used in various plants, for example, eggplant grafting is one of them. Eggplant grafting is a method in eggplant planting, and eggplant grafted seedlings are a commonly used seedling raising method in eggplant grafting. The yield and quality of eggplant can be improved by planting eggplant grafted seedlings. However, the quality control of eggplant grafted seedlings still mainly relies on manual experience, which lacks scientificity and accuracy. Therefore, it is necessary to provide a quality control system and method for eggplant grafted seedlings.

[0003] The existing grafted seedling quality management system realizes quality management of grafted seedlings by real-time monitoring of the grafted seedlings, analyzing the growth status of the grafted seedlings, clarifying the quality of the grafted seedlings, and performing corresponding management functions.

[0004] For example, the invention patent with announcement number: CN111066509B announces a method for improving the quality of zero-cotyledon grafted seedlings of watermelon rootstocks, including: raising seedlings of rootstocks and raising seedlings of scions; grafting is performed when the rootstock has one leaf and one heart, i.e., about 10 days after sowing, and when the cotyledons of the scion are just flattened, i.e., about 7 days after sowing, and the cotyledons of the rootstock are completely removed, and the grafting site is located about 1 cm below the cotyledons of the rootstock; after the grafting is completed, 0.1mM IAA is sprayed on the rootstock part, 1 ml per plant on average, and then 2% sucrose is used for root irrigation, 4 ml per plant; 0.1mM IAA and 2% sucrose are sprayed on the grafted seedlings every other day, 1 ml per plant, and sprayed three times in succession.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1 As shown, it is a flow chart of a quality control method for grafted eggplant seedlings provided in an embodiment of the present application, the method comprising the following steps: obtaining standard data for eggplant grafting; monitoring the process of eggplant grafting and acquiring data to obtain parameter data affecting eggplant grafting; analyzing the qualification degree of spare rootstocks according to the standard data for eggplant grafting and the parameter data affecting eggplant grafting; analyzing the qualification degree of scion wood according to the standard data for eggplant grafting and the parameter data affecting eggplant grafting; grafting qualified spare rootstocks with qualified scion wood to obtain grafted eggplant seedlings; monitoring the growth process of grafted eggplant seedlings to obtain environmental parameter data for grafted seedlings; and controlling the quality of grafted eggplant seedlings according to the standard data for eggplant grafting and the environmental parameter data for grafted seedlings.

[0033] Furthermore, the specific analysis process for obtaining standard data for eggplant grafting is as follows: historical eggplant grafting data is obtained and the success rate of eggplant grafting is analyzed, the eggplant grafting success rates are arranged in order from large to small to obtain the first eggplant grafting success rate, that is, to obtain the maximum success rate of eggplant grafting, and the environmental parameter data corresponding to the maximum success rate of eggplant grafting is obtained, that is, to obtain standard data for eggplant grafting.

[0034] In this embodiment, there are many methods for eggplant grafting, such as cutting method, plugging method, cleft grafting method, etc. Different grafting methods have different effects on the survival rate of grafting and the growth of plants. In the historical eggplant grafting data, there are grafting survival rates, grafting data and growth trends of eggplant grafted seedlings at various growth stages after survival and corresponding growth environment conditions corresponding to various eggplant grafting methods. The grafting survival rates corresponding to the grafting methods used in the invention under various conditions are obtained, and the survival rates are arranged in order from large to small. The survival rate ranked first is taken as the maximum success rate of eggplant grafting. The grafting data corresponding to the maximum success rate of eggplant grafting and the growth trends of eggplant grafted seedlings at various growth stages after survival and the corresponding growth environment conditions are obtained, so as to obtain the standard data of eggplant grafting.

[0035] Furthermore, the specific analysis process of analyzing the qualification degree of the spare rootstock according to the eggplant grafting standard data and the eggplant grafting influencing parameter data is as follows: obtaining the rootstock suitability parameter data according to the eggplant grafting influencing parameter data; obtaining the rootstock suitability assessment coefficient according to the eggplant grafting standard data and the rootstock suitability parameter data, and the rootstock suitability assessment coefficient is used to reflect the suitability of the spare rootstock for eggplant grafting; analyzing the qualification degree of the spare rootstock according to the rootstock suitability assessment coefficient.

[0036] In the present embodiment, stock is the plant part used as basis in grafting, usually has stronger disease resistance and adaptability.In eggplant grafting, selecting suitable stock is most important for the survival of grafting and the growth of plant.From numerous spare stock, select the spare stock that is more suitable for eggplant grafting to carry out eggplant grafting, be conducive to improving survival rate and the quality of eggplant grafted seedlings.

[0037] Before obtaining the rootstock suitability evaluation coefficient based on the eggplant grafting standard data and the rootstock suitability parameter data, the rootstock suitability parameter data is processed, including data cleaning, denoising, filling missing values, removing duplicate records, etc., to ensure the quality of the rootstock suitability parameter data, and data conversion of the rootstock suitability parameter data, converting the rootstock suitability parameter data into a unified format for subsequent analysis. The rootstock suitability evaluation coefficient is obtained by analyzing the rootstock suitability parameter data after data processing, so that the accuracy of the rootstock suitability evaluation coefficient is higher, which is conducive to more accurately analyzing the qualification of the spare rootstock according to the rootstock suitability evaluation coefficient.

[0038] Furthermore, the specific method for obtaining the stock suitability evaluation coefficient is as follows: obtaining the number of spare stock and numbering the spare stock; performing multiple data collection on the spare stock, obtaining the number of data collections, and numbering the number of data collections; obtaining the preset weight ratio of the stock diameter, stock height, and stock hardness from the database; obtaining the eggplant grafting standard data and the stock suitability parameter data; constructing a stock suitability evaluation coefficient calculation formula based on the eggplant grafting standard data and the stock suitability parameter data; the specific stock suitability evaluation coefficient calculation formula is:

[0039]

[0040] In the formula, It is represented as the stock suitability evaluation coefficient of the m0th spare stock, m0=1,2,...,m, m0 represents the number of the spare stock, m represents the total number of spare stock, It is represented by the rootstock diameter of the m0th spare rootstock at the s0th data collection, s0=1,2,...,s, s0 represents the number of data collection times, s represents the total number of data collection times, It is represented by the height of the m0th spare rootstock at the time of the s0th data collection, It is expressed as the rootstock hardness of the m0th spare rootstock at the s0th data collection, TZ is expressed as the reference value of the rootstock diameter, TG is expressed as the reference value of the rootstock height, TH is expressed as the reference value of the rootstock hardness, L1 is expressed as the weight ratio of the rootstock diameter in the rootstock suitability assessment coefficient, L2 is expressed as the weight ratio of the rootstock height in the rootstock suitability assessment coefficient, and L3 is expressed as the weight ratio of the rootstock hardness in the rootstock suitability assessment coefficient.

[0041] In this embodiment, historical tassel wood parameter data is obtained, and the relationship between stock diameter, stock height, stock hardness and stock suitability evaluation coefficient is found by analyzing the historical tassel wood parameter data, and a fitting curve is obtained by using a multiple linear regression method, and the fitting effect of the fitting curve is obtained by analyzing the mean square error of the fitting curve, and the fitting curve corresponding to the minimum mean square error is used as the first fitting curve, and the corresponding weight ratio is obtained by the first fitting curve. The real-time stock diameter, stock height, and stock hardness are brought into the first fitting curve to obtain the weight ratio corresponding to the stock diameter, stock height, and stock hardness.

[0042] In actual operation, factors such as the diameter, hardness and elasticity of the rootstock do need to be considered to ensure the success rate of grafting and the healthy growth of the plant. When grafting eggplant, rootstocks with moderate diameter, tough texture and good growth potential are usually selected. A diameter that is too small may lead to insufficient nutrient supply to the grafted site, while a diameter that is too large may increase the difficulty of grafting and make healing difficult. Excessive hardness of the rootstock makes it difficult for the grafted seedlings to heal, and too low hardness of the rootstock makes it easy for the grafted seedlings to fall over, affecting the growth of the grafted seedlings. The height of the spare rootstock that is too high or too low will have an adverse effect on the healing speed of the grafted part. Only by comprehensively analyzing the three aspects of rootstock diameter, rootstock height and rootstock hardness when selecting the spare rootstock can we more comprehensively analyze the qualification of the spare rootstock for eggplant grafting.

[0043] The diameter, height and hardness of the spare rootstock were measured using a digital caliper, an electronic distance meter and a hardness tester to obtain the rootstock diameter, rootstock height and rootstock hardness. The rootstock diameter, height and hardness corresponding to the maximum success rate of eggplant grafting at that moment were extracted from the eggplant grafting standard data to obtain the reference value of rootstock diameter, the reference value of rootstock height and the reference value of rootstock hardness.

[0044] In the algorithm of this embodiment, the eggplant grafting standard data and the stock suitability parameter data are analyzed by using the hyperbolic cotangent function to obtain the stock suitability assessment coefficient, which smoothes the influence of the outliers in the eggplant grafting standard data and the stock suitability parameter data on the stock suitability assessment coefficient, making the stock suitability assessment coefficient more accurate.

[0045] Furthermore, the specific analysis process of analyzing the qualification of the backup rootstock according to the rootstock suitability assessment coefficient is as follows: obtaining the rootstock suitability assessment coefficient, obtaining the first rootstock suitability threshold and the second rootstock suitability threshold; when the rootstock suitability assessment coefficient is greater than the first rootstock suitability threshold and less than the second rootstock suitability threshold, it indicates that the backup rootstock is qualified and can be used for eggplant grafting; when in other situations, it indicates that the backup rootstock is unqualified and cannot be used for eggplant grafting.

[0046] In this embodiment, historical data related to rootstock evaluation is obtained, and historical rootstock suitability evaluation coefficients are analyzed based on the historical data related to rootstock evaluation. A first rootstock suitability threshold and a second rootstock suitability threshold are set in combination with the historical rootstock suitability coefficients and the corresponding rootstock qualification level.

[0047] Get the first and second thresholds of stock suitability. The first and second thresholds of stock suitability are μ1 and μ2 respectively. The value range of μ1 is [1.26, 1.27], and the value range of μ2 is [1.35, 1.36]. When the stock suitability evaluation coefficient is greater than the first threshold of stock suitability and less than the second threshold of stock suitability, that is, When the backup rootstock is qualified, it can be used for eggplant grafting; when it is in other situations, that is, or When it is, it means that the spare rootstock is unqualified and cannot be used for eggplant grafting.

[0048] Furthermore, the specific analysis process of analyzing the qualification degree of scion wood according to the eggplant grafting standard data and the eggplant grafting influencing parameter data is as follows: obtaining the scion wood treatment qualification degree parameter data according to the eggplant grafting influencing parameter data; obtaining the scion wood treatment qualification degree evaluation index according to the eggplant grafting standard data and the scion wood treatment qualification degree parameter data, and the scion wood treatment qualification degree evaluation index is used to reflect the suitability of eggplant scion wood for eggplant grafting; analyzing the qualification degree of eggplant scion wood according to the scion wood treatment qualification degree evaluation index.

[0049] In the present embodiment, the scion is the plant part used as the top in the grafting, which usually has good fruit quality and growth characteristics. In eggplant grafting, selecting a suitable scion can improve the fruit quality and yield of the grafted plant. Eggplant grafting will follow some basic principles to determine the cutting angle: cutting direction: the cutting surface of the scion should usually be oblique, which helps to increase the cut surface area, promote healing and improve the exchange of nutrients. The bevel method refers to beveling the cut surface of the stock and the scion so that the cut surface presents a 45-degree angle; cutting depth: the cutting depth of the scion should be moderate so as to be able to have good contact with the stock; cut surface matching: the cut surface of the stock and the scion should match as much as possible to ensure that the contact area between the scion and the stock is the largest, which is conducive to healing and the transfer of nutrients; cutting quality: the cut surface should be smooth and burr-free during cutting, which can reduce obstacles in the healing process, promote healing and reduce the chance of pathogen invasion. Since there are too many parameters that affect the quality of the eggplant tassel, in this embodiment, the qualification of the eggplant tassel is analyzed in terms of the number of times the eggplant tassel is cut, the maximum cutting angle of the eggplant tassel, and the minimum cutting angle of the eggplant tassel.

[0050] The specific method for obtaining the qualified degree evaluation index of tassel wood treatment is as follows: obtaining the number of eggplant tassel woods that have completed the grafting treatment and numbering the eggplant tassel woods; collecting data on the eggplant tassel woods for multiple times, obtaining the number of data collections, and numbering the number of data collections; obtaining the qualified degree parameter data of tassel wood treatment; obtaining the preset eggplant tassel wood cutting number, the maximum value of the eggplant tassel wood cutting angle, and the minimum value of the eggplant tassel wood cutting angle from the database; constructing a calculation formula according to the qualified degree parameter data of tassel wood treatment; the specific calculation formula for the qualified degree evaluation index of tassel wood treatment is:

[0051]

[0052] In the formula, It is the evaluation index of the qualified degree of the q0th eggplant scion treatment, q0 = 1, 2, ..., q, q0 is the number of the eggplant scion, q is the total number of the eggplant scion, It represents the number of times the q0th arborvitae is cut at the c0th data collection, c0 represents the number of data collection times, c0=1,2,...,c, c represents the total number of data collection times, It is represented by the maximum cutting angle of the q0th eggplant thorn at the c0th data collection. It is represented by the maximum cutting angle of the q0th eggplant thorn at the c0th data collection. It is represented by the minimum cutting angle of the q0th eggplant tassel at the c0th data collection, SQ is represented by the reference cutting times of the eggplant tassel, SA is represented by the maximum reference cutting angle of the eggplant tassel, SC is represented by the minimum reference cutting angle of the eggplant tassel, R1 is represented by the weight ratio of the eggplant tassel cutting times in the tassel treatment qualification evaluation index, R2 is represented by the weight ratio of the maximum cutting angle of the eggplant tassel in the tassel treatment qualification evaluation index, and R3 is represented by the weight ratio of the minimum cutting angle of the eggplant tassel in the tassel treatment qualification evaluation index.

[0053] According to the relevant historical data of tassel wood assessment, the mapping relationship between the number of eggplant tassel wood cutting, the maximum value of the eggplant tassel wood cutting angle, the minimum value of the eggplant tassel wood cutting angle and the evaluation index of the qualified degree of tassel wood treatment is established to obtain a mapping relationship table. According to the real-time number of eggplant tassel wood cutting, the maximum value of the eggplant tassel wood cutting angle and the minimum value of the eggplant tassel wood cutting angle, the mapping relationship table is queried to obtain the weight ratio of the number of eggplant tassel wood cutting, the maximum value of the eggplant tassel wood cutting angle and the minimum value of the eggplant tassel wood cutting angle.

[0054] The number of eggplant scion cuttings refers to the total number of cuttings of the eggplant scion before grafting with the spare rootstock. The total number of cuttings obtained by counting the number of times the eggplant scion is cut is the number of eggplant scion cuttings. The maximum cutting angle of the grafted seedling refers to the maximum angle between the cutting surface and the axis of the eggplant stem. The minimum cutting angle of the eggplant scion refers to the minimum angle between the cutting surface and the axis of the eggplant stem. All cutting angles of the grafted eggplant seedlings are measured by a protractor, an electronic angle meter, and a grafting angle meter. All cutting angles are arranged in order from large to small, and the first and last cutting angles are used as the maximum and minimum cutting angles of the eggplant scion. The number of cuttings, the maximum cutting angle, and the minimum cutting angle corresponding to the maximum success rate of eggplant grafting at this moment are extracted from the eggplant grafting standard data, that is, the number of cuttings of the eggplant scion, the maximum cutting angle of the eggplant scion, and the minimum cutting angle of the eggplant scion.

[0055] When cutting, the cut surface should be smooth and burr-free, which can reduce obstacles in the healing process, promote healing and reduce the chance of pathogen invasion. Therefore, the number of cuttings of eggplant thorn wood should not be too many. The maximum cutting angle of eggplant thorn wood should not be too large, otherwise it may lead to insufficient nutrient supply at the grafting site and affect the survival rate. The minimum cutting angle of eggplant thorn wood should not be too small, otherwise it may cause the grafting site to be unstable and easy to fall off. By comprehensively analyzing the number of cuttings of eggplant thorn wood, the maximum cutting angle of eggplant thorn wood and the minimum cutting angle of eggplant thorn wood, the evaluation index of the qualified degree of thorn wood treatment can be obtained, which can more accurately analyze the qualified degree of wife thorn wood.

[0056] The algorithm of this embodiment uses the inverse tangent function to smooth out the outliers in the tassel wood treatment qualification parameter data, thereby reducing the impact of outliers on the tassel wood treatment qualification evaluation index, which is conducive to obtaining a more accurate tassel wood treatment qualification evaluation index, and facilitates a more accurate comprehensive analysis of the suitability of the eggplant tassel wood for grafting from three aspects: the number of times the eggplant tassel wood is cut, the maximum cutting angle of the eggplant tassel wood, and the minimum cutting angle of the eggplant tassel wood.

[0057] Furthermore, the specific analysis process of analyzing the qualification degree of eggplant fringe wood according to the fringe wood qualification degree evaluation index is as follows: obtaining the fringe wood qualification degree evaluation index, obtaining the first fringe wood qualification threshold and the second fringe wood qualification threshold, comparing the fringe wood qualification degree evaluation index with the first fringe wood qualification threshold and the second fringe wood qualification threshold; when the fringe wood qualification degree evaluation index is greater than the first fringe wood qualification threshold and less than the second fringe wood qualification threshold, it indicates that the eggplant fringe wood is qualified and can be used for eggplant grafting; when it is in other situations, it indicates that the eggplant fringe wood is unqualified and cannot be used for eggplant grafting.

[0058] In this embodiment, historical spicate processing related data are obtained, and historical spicate processing qualification evaluation indicators are analyzed based on the historical spicate processing related data. The qualification of the spicate corresponding to the analysis of the historical spicate processing qualification evaluation indicators is determined and the first threshold value for qualified spicate processing and the second threshold value for qualified spicate processing are set.

[0059] Obtain the first qualified threshold for spicate wood treatment and the second qualified threshold for spicate wood treatment, which are ω1 and ω2 respectively, and compare the qualified degree evaluation index of spicate wood treatment with the first qualified threshold for spicate wood treatment and the second qualified threshold for spicate wood treatment. When the qualified degree evaluation index of spicate wood treatment is greater than the first qualified threshold for spicate wood treatment and less than the second qualified threshold for spicate wood treatment, that is, When it is, it means that the eggplant scion wood is qualified and can be used for eggplant grafting; when it is in other situations, that is, or When it is, it means that the eggplant scion wood is unqualified and cannot be used for eggplant grafting.

[0060] Furthermore, the specific analysis process for controlling the quality of grafted eggplant seedlings based on the eggplant grafting standard data and the grafted seedling environmental parameter data is as follows: obtaining the grafted seedling environment qualification degree assessment index based on the eggplant grafting standard data and the grafted seedling environmental parameter data, and the grafted seedling environment qualification degree assessment index is used to reflect the qualification degree of the eggplant grafted seedling environment; analyzing the quality of the grafted eggplant seedlings and controlling them based on the grafted seedling environment qualification degree assessment index.

[0061] In this embodiment, the management measures after grafting are crucial to the survival of the graft and the growth of the plant. It is necessary to properly control the temperature, humidity and light, apply fertilizers and water in time, and pay attention to the prevention and control of diseases and insect pests. Therefore, managing the environment of the grafted seedlings is one of the key points to improve the quality of the grafted seedlings.

[0062] The specific method for obtaining the grafted seedling environment qualification evaluation index is as follows: grafting qualified spare rootstocks with qualified eggplant scion woods to obtain eggplant grafted seedlings, obtaining the number of eggplant grafted seedlings, and numbering the eggplant grafted seedlings; setting a preset time period, obtaining the number of preset time periods, and numbering the preset time periods; acquiring data of the eggplant grafted seedlings multiple times in the preset time period, and numbering the number of data acquisitions; acquiring grafted seedling environment parameter data; acquiring the preset weight ratio of the average temperature value at the first distance of the grafted seedlings and the average humidity value at the first distance of the grafted seedlings from the database; constructing a grafted seedling environment qualification evaluation index calculation formula according to the grafted seedling environment parameter data; the specific grafted seedling environment qualification evaluation index calculation formula is:

[0063]

[0064] In the formula, It is represented by the evaluation index of the grafted seedling environment qualification of the j0th eggplant grafted seedling in the d0th preset time period, j0=1,2,...,j, j0 represents the number of the eggplant grafted seedling, j represents the total number of the eggplant grafted seedlings, d0=1,2,...,d, d0 represents the number of the preset time period, d0 represents the total number of the preset time period, It is represented by the average temperature of the grafted eggplant seedling at the first distance when the data of the j0th grafted eggplant seedling is acquired at the h0th time in the d0th preset time period, h0=1,2,...,h, h0 represents the number of data acquisition times, h represents the total number of data acquisition times, It is represented by the average humidity of the grafted eggplant seedling at the first distance when the data of the j0th grafted eggplant seedling is obtained at the h0th time in the d0th preset time period, It is represented by the reference average temperature of the grafted seedling at the first distance in the d0th preset time period, It is expressed as the reference average humidity value at the first distance of the grafted seedlings in the d0th preset time period, N1 is expressed as the weight ratio of the average temperature value at the first distance of the grafted seedlings in the grafted seedling environment qualification evaluation index, and N2 is expressed as the weight ratio of the average humidity value at the first distance of the grafted seedlings in the grafted seedling environment qualification evaluation index.

[0065] According to the historical data related to the grafted seedling environmental assessment, a mapping relationship is established between the average temperature at the first distance of the grafted seedlings and the average humidity at the first distance of the grafted seedlings and the grafted seedling environmental qualification evaluation index to obtain a mapping relationship table. According to the real-time average temperature at the first distance of the grafted seedlings and the average humidity at the first distance of the grafted seedlings, the mapping relationship table is queried to obtain the weight ratio of the average temperature at the first distance of the grafted seedlings and the average humidity at the first distance of the grafted seedlings.

[0066] The temperature and humidity data at the first distance from the grafted eggplant seedlings are measured using a temperature and humidity sensor, and the average values ​​are taken to obtain the temperature average value and the humidity average value, that is, to obtain the temperature average value at the first distance of the grafted seedlings and the humidity average value at the first distance of the grafted seedlings. The temperature data and humidity data at the first distance corresponding to the grafted seedlings at this moment are extracted from the eggplant grafting standard data, that is, to obtain the temperature reference average value at the first distance of the grafted seedlings and the humidity reference average value at the first distance of the grafted seedlings.

[0067] The greater the deviation between the average temperature at the first distance of the grafted seedlings and the reference average temperature at the first distance of the grafted seedlings, and the greater the deviation between the average humidity at the first distance of the grafted seedlings and the reference average humidity at the first distance of the grafted seedlings, the greater the gap between the environmental conditions of the eggplant grafted seedlings and the standard environmental conditions, the greater the degree of impact on the quality of the eggplant grafted seedlings, and the more likely it is that the quality of the eggplant grafted seedlings will be poor.

[0068] In the algorithm of this embodiment, the abnormal data in the average temperature value at the first distance of the grafted seedlings and the average humidity value at the first distance of the grafted seedlings are smoothed by using a hyperbolic cosine function, so that a more accurate grafted seedling environment qualification evaluation index can be obtained according to the average temperature value at the first distance of the grafted seedlings and the average humidity value at the first distance of the grafted seedlings, which is conducive to more accurate analysis and control of the quality of grafted eggplant seedlings according to the grafted seedling environment qualification evaluation index.

[0069] In a specific embodiment, Figure 2 As shown, it is a curve chart of the grafted seedling environment qualification evaluation index provided in the embodiment of the present application, with the average humidity value at the first distance of the grafted seedling as the independent variable, and the grafted seedling environment qualification evaluation index as the dependent variable. For example, when the fourth eggplant grafted seedling is subjected to data acquisition in the second preset time period, through the increase and decrease analysis of curve one, curve two and curve three, it can be known that when the average humidity value at the first distance of the grafted seedling is larger, the grafted seedling environment qualification evaluation index is larger; when the average humidity value at the first distance of the grafted seedling is smaller, the grafted seedling environment qualification evaluation index is smaller. The statistical table of relevant data of the grafted seedling environment qualification evaluation index is shown in Table 1:

[0070] Table 1 Statistical table of relevant data of evaluation index of environmental qualification of grafted seedlings

[0071]

[0072]

[0073] The suitable temperature range for the second preset time period of grafted eggplant seedlings is 22°C to 28°C. When the temperature reference average values ​​at the first distance of the grafted seedlings of curves one, two and three are 22°C, 24°C and 26°C respectively, and other parameters are consistent, the environmental qualification evaluation indexes of grafted seedlings of curves one, two and three are 1.54, 1.53 and 1.51 respectively. It can be seen that when the humidity average value at the first distance of the grafted seedlings is consistent with other parameters, the larger the temperature reference average value at the first distance of the grafted seedlings, the smaller the environmental qualification evaluation index of the grafted seedlings.

[0074] Furthermore, the specific analysis process of analyzing the quality of grafted eggplant seedlings and conducting management and control based on the grafted seedlings environment qualification evaluation index is as follows: obtaining the grafted seedlings environment qualification evaluation index, obtaining the first threshold value of grafted seedlings environment qualification and the second threshold value of grafted seedlings environment qualification; when the grafted seedlings environment qualification evaluation index is greater than the first threshold value of grafted seedlings environment qualification and less than the second threshold value of grafted seedlings environment qualification, it indicates that the environment of the grafted eggplant seedlings is qualified and no management and control is required; when in other situations, it indicates that the environment of the grafted eggplant seedlings is unqualified, and the environment of the grafted eggplant seedlings is controlled, and the control includes adjusting the environmental temperature and humidity of the grafted eggplant seedlings. After the control and control is completed, the grafted seedlings environment qualification evaluation index of the grafted eggplant seedlings is analyzed until the environment of the grafted eggplant seedlings is analyzed to be qualified, and then the management and control is stopped.

[0075] In this embodiment, historical grafting environment related data is obtained, and a historical grafting seedling environment qualification evaluation index is analyzed based on the historical grafting environment related data. The qualification degree of the eggplant grafting seedling environment corresponding to the analysis of the historical grafting seedling environment qualification evaluation index is determined, and a first threshold value for the grafting seedling environment qualification and a second threshold value for the grafting seedling environment qualification are set.

[0076] The first threshold value of grafted seedling environment qualification and the second threshold value of grafted seedling environment qualification are obtained. The first threshold value of grafted seedling environment qualification and the second threshold value of grafted seedling environment qualification are ρ1 and ρ2 respectively. When the grafted seedling environment qualification evaluation index is greater than the first threshold value of grafted seedling environment qualification and less than the second threshold value of grafted seedling environment qualification, that is, When it is, it means that the environment for grafted eggplant seedlings is qualified and no control is required; when it is in other situations, that is, or When , it means that the environment of the grafted eggplant seedlings is unqualified, and the environment of the grafted eggplant seedlings is controlled, including adjusting the environmental temperature and humidity of the grafted eggplant seedlings. After the control is completed, the grafted seedling environment qualification evaluation index of the grafted eggplant seedlings is analyzed until the environment of the grafted eggplant seedlings is analyzed to be qualified, then the control is stopped.

[0077] By analyzing the grafted seedling environment qualification evaluation index, the qualification of the eggplant grafted seedling environment is clarified, and corresponding control functions are performed. For example, when it is analyzed that the environment of the eggplant grafted seedling is unqualified, the environmental temperature and humidity of the eggplant grafted seedling are adjusted, and the adjustment is stopped until the environmental temperature and humidity are adjusted to a reasonable range, thereby achieving the function of controlling the quality of the eggplant grafted seedlings.
