[0014] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0016] Figure 1The flowchart of the lily seedling environment control method according to an embodiment of the present invention is exemplarily shown, and the method comprises: step S101, at multiple moments in the current monitoring cycle, respectively detecting the temperature and light intensity of the lily seedling environment; step S102, at the start moment and the end moment of the current monitoring cycle, respectively detecting the soil moisture, and detecting the content information of multiple fertilizer elements in the soil of the lily seedling environment by a spectrometer; step S103, in the soil of the lily seedling environment, selecting multiple test points; step S104, using a probe to insert the test point at a preset speed, and at multiple moments during the insertion process , respectively detecting the resistance data received by the probe; step S105, determining the external condition suitability score of the lily seedling raising environment according to the temperature and light intensity of the lily seedling raising environment; step S106, determining the soil condition suitability score of the lily seedling raising environment according to the soil moisture, the resistance data and the content information of the plurality of fertilizer elements; step S107, determining the lily seedling raising environment suitability score according to the external condition suitability score and the soil condition suitability score; step S108, adjusting the lily seedling raising environment for the next monitoring cycle according to the lily seedling raising environment suitability score.

[0017] According to the lily seedling environment control method of the embodiment of the present invention, the seedling environment when soil is used as the culture matrix can be monitored. In addition to monitoring the external environment such as temperature and light intensity, the soil breeding conditions can also be monitored based on data such as soil moisture, resistance data and fertilizer element content information, so as to timely discover and adjust and control unsuitable conditions, thereby improving the breeding success rate using soil as the culture matrix, and is easy to popularize and produce.

[0018] According to one embodiment of the present invention, in step S101, each monitoring cycle can be one day or more days, and the interval between adjacent moments can be 15 minutes, 30 minutes, 60 minutes, etc. The present invention does not limit the duration of the monitoring cycle and the time interval between adjacent moments. At each moment of the current monitoring cycle, the temperature and light intensity of the lily seedling raising environment can be monitored to determine whether the external environment is suitable for lily seedling raising.

[0019] According to one embodiment of the present invention, in step S102, at the start and end of the current monitoring cycle, soil moisture can be detected, and the content information of various fertilizer elements in the soil of the lily seedling raising environment can be detected by a spectrometer. The soil moisture and the content information of various fertilizer elements detected at the end of the previous monitoring cycle can be used as the soil moisture and the content information of various fertilizer elements at the start of the current monitoring cycle, and the soil moisture and the content information of various fertilizer elements detected at the end of the current monitoring cycle can also be used as the soil moisture and the content information of various fertilizer elements at the start of the next monitoring cycle.

[0020] According to one embodiment of the present invention, in step S103, multiple test points can be selected in the soil of the lily seedling environment. For example, the placement position of the bulbs used for lily seedling cultivation can be used as the center of the circle, and the radius of the lily growth range can be set. Test points are selected at multiple positions within the circular area corresponding to the center and the radius. The distances between each test point and the center of the circle are different, so that information about the soil at more positions can be obtained, such as information related to the looseness of the soil.

[0021] According to one embodiment of the present invention, in step S104, the soil suitable for lily breeding should have an appropriate degree of looseness, so as to have good air permeability and drainage, and facilitate the lily to absorb nutrients and grow and develop. In order to detect whether the soil has a good degree of looseness, a probe can be used to insert a test point at a preset speed, and the test point is a test point selected on a plane circular area. When inserting the probe, the probe can be inserted in a vertical direction, and the insertion speed is a preset speed. When the insertion speed is a uniform preset speed, the resistance data received by the probe during insertion is related to the looseness of the soil, that is, the greater the resistance data received by the probe, the more compact the soil is and the lower the looseness is. On the contrary, the smaller the resistance data received by the probe, the more loose the soil is.

[0022] According to an embodiment of the present invention, in step S105, it can be determined whether the external conditions are suitable for lily seedling cultivation based on the temperature and light intensity of the lily seedling cultivation environment detected above. Determining the suitability score of the external conditions of the lily seedling cultivation environment according to the temperature and light intensity of the lily seedling cultivation environment includes: setting a suitable light intensity range; setting a suitable temperature range; determining the suitability score of the external conditions of the lily seedling cultivation environment according to the light intensity range, the suitable temperature range, the temperature and the light intensity.

[0023] According to one embodiment of the present invention, a suitable light intensity range suitable for lily seedling cultivation can be set, for example, 6000 Lux-8000 Lux. A suitable temperature range suitable for lily seedling cultivation can also be set, for example, 15°C-25°C.

[0024] According to one embodiment of the present invention, the external condition suitability score of the lily seedling raising environment is determined according to the suitable light intensity range, the suitable temperature range, the temperature and the light intensity, including: determining the external condition suitability score of the lily seedling raising environment according to formula (1): ,

[0025] (1), where is the temperature at the i-th moment of the current monitoring cycle, is the suitable temperature range, n is the number of moments in the current monitoring cycle, is the light intensity at the i-th moment of the current monitoring cycle, For the appropriate light intensity range, For the preset suitable light duration, is the time interval between adjacent moments, is the conditional function, and is the preset weight, i≤n, and both i and n are positive integers.

[0026] According to one embodiment of the present invention, in formula (1), the conditional function It means that when the temperature at the i-th moment is within the suitable temperature range, the conditional function value is 1, otherwise it is 0. Therefore, is the total number of times the temperature detected is within the appropriate temperature range in the current monitoring cycle. The ratio of the total number of moments that fall within the suitable temperature range to the number of moments can be used to indicate the temperature suitability of the lily seedling raising environment during the current monitoring period.

[0027] According to one embodiment of the present invention, in formula (1), It means that when the light intensity at the i-th moment belongs to the appropriate light intensity range, the conditional function value is 1, otherwise it is 0. Therefore, It is the total number of moments in the current monitoring cycle when the detected light intensity belongs to the suitable light intensity range. Further, in the lily seedling raising process, it is not necessary to make the lily bulbs in the suitable light intensity range at all times, but to make the lily bulbs in the suitable light intensity range within a certain time range. Therefore, the suitable light duration can be set, and the time that the lily bulbs are in the suitable light intensity range in each monitoring cycle is the suitable light duration. For example, if the duration of each monitoring cycle is 1 day, the suitable light duration can be set to 12 hours, that is, the lily bulbs are in the suitable light intensity range for 12 hours every day, so as to meet the lighting conditions for lily seedling raising. That is, the number of moments corresponding to the appropriate light duration. is the relative deviation between the total number of moments when the detected light intensity falls within the appropriate light intensity range and the number of moments corresponding to the appropriate light duration. It can represent the similarity between the total number of moments when the detected light intensity falls within the suitable light intensity range and the number of moments corresponding to the suitable light duration, and can be used to indicate the light suitability of the lily seedling environment in the current monitoring period.

[0028] According to one embodiment of the present invention, the above-mentioned item representing the temperature suitability of the lily seedling environment in the current monitoring period and the item representing the light suitability of the lily seedling environment in the current monitoring period can be weighted and summed to obtain a suitability score for the external conditions of the lily seedling environment, which can be used to represent the suitability of the external conditions of the lily seedling environment.

[0029] In this way, the temperature suitability of the lily seedling environment can be determined by counting the total number of moments within the suitable temperature range in the current monitoring period and the ratio of the number of moments, and the light suitability of the lily seedling environment can be determined by counting the relative deviation between the total number of moments within the suitable light intensity range and the number of moments corresponding to the suitable light duration in the current monitoring period, thereby determining the external condition suitability score, so that the external condition suitability score can accurately and objectively describe the suitability of the external conditions of the lily seedling environment.

[0030] According to an embodiment of the present invention, in step S106, in addition to monitoring the suitability of the above external conditions, the suitability of the soil condition for lily seedling cultivation can also be monitored. According to the soil moisture, the resistance data and the content information of the multiple fertilizer elements, the soil condition suitability score of the lily seedling cultivation environment is determined, including: determining the soil cultivation suitability score according to the soil moisture and the content information of the multiple fertilizer elements; determining the soil looseness suitability score according to the soil moisture and the resistance data; determining the soil condition suitability score of the lily seedling cultivation environment according to the soil cultivation suitability score and the soil looseness suitability score.

[0031] According to one embodiment of the present invention, whether the content of nutrients required for lily seedling cultivation in the soil is appropriate can be determined based on soil moisture and content information of multiple fertilizer elements. The multiple fertilizer elements may include nitrogen, phosphorus, potassium and other elements, and the present invention does not limit the types of the multiple fertilizer elements.

[0032] According to an embodiment of the present invention, the soil cultivation suitability score is determined based on the soil moisture and the content information of the multiple fertilizer elements, including: setting a suitable humidity range; setting a suitable content range of various fertilizer elements; and determining the soil cultivation suitability score according to formula (2). , (2), where is the soil moisture at the beginning of the current monitoring period, is the soil moisture at the end of the current monitoring period, For the suitable humidity range, is the content information of the jth fertilizer element at the beginning of the current monitoring cycle, is the content information of the jth fertilizer element at the end of the current monitoring cycle, is the suitable content range of the jth fertilizer element, is the conditional function, and is the preset weight, m ​​is the number of fertilizer elements, j≤m, and both j and m are positive integers.

[0033] According to one embodiment of the present invention, since the change rules of soil moisture and the content information of various fertilizer elements are different from the above-mentioned external conditions such as light intensity and temperature, the change speed is slow and the change is more uniform. Therefore, the soil moisture and the content information of various fertilizer elements at the start and end of the current monitoring cycle can be detected, and the average value of the soil moisture at the start and end time is used to represent the average soil moisture in the current monitoring cycle, and the average value of the content information of various fertilizer elements at the start and end time is used as the average content information of various fertilizer elements in the current monitoring cycle. And the appropriate humidity range can be set to determine whether the average soil moisture belongs to the appropriate humidity range, and the appropriate content range of various fertilizer elements can be set, and it can be determined whether the average value of the content information of various fertilizer elements belongs to the appropriate content range, so as to determine whether the nutrients in the soil are suitable for lily seedling cultivation.

[0034] According to one embodiment of the present invention, in formula (2), the conditional function It means that when the average soil moisture is within the suitable humidity range, the conditional function value is 1, otherwise it is 0. It can be used to indicate whether the average soil moisture in the current monitoring period is suitable for lily seedling cultivation. Indicates that when the average value of the content information of the jth fertilizer element is suitable for the appropriate content range, the conditional function value is 1, otherwise it is 0, which can be used to indicate whether the average value of the content information of the jth fertilizer element in the current monitoring period is suitable for lily seedling cultivation. The function value of the conditional function corresponding to the average value of the content information of various fertilizer elements and the function value of the conditional function corresponding to the average soil moisture can be weighted and summed to obtain the soil cultivation suitability score, which is used to describe whether the nutrients in the soil are suitable for lily seedling cultivation, where The closer the soil cultivation suitability score is to 1, the more suitable the soil nutrients are for lily seedling cultivation; the closer the soil cultivation suitability score is to 0, the less suitable the soil nutrients are for lily seedling cultivation.

[0035] In this way, the conditional function can be used to determine whether the average content information of nutrients such as moisture and various fertilizer elements in the soil is within the appropriate content range to solve the soil cultivation suitability score. The soil cultivation suitability score can then be used to accurately describe whether the nutrients contained in the soil are suitable for lily seedling cultivation, thereby improving the accuracy and objectivity of the soil cultivation suitability score.

[0036] According to one embodiment of the present invention, in addition to determining whether the content information of various nutrients is suitable for lily seedling cultivation, it is also possible to determine whether the looseness of the soil is suitable for lily seedling cultivation. Whether the soil is loose and whether the looseness of the soil is suitable for lily seedling cultivation can be determined based on the resistance data and soil moisture obtained above.

[0037] According to one embodiment of the present invention, a soil looseness suitability score is determined based on the soil moisture and the resistance data, including: sampling from the soil of a lily seedling raising environment as a test sample; changing the soil moisture of some of the test samples; after the soil moisture of some of the test samples is changed, detecting the test soil moisture and initial volume of each test sample; inserting the test sample at a preset speed using a probe, and detecting the test resistance data of the probe at multiple moments during the insertion process; placing the test sample on a hydraulic device, and using the hydraulic device to squeeze the test sample with a preset force, and after the squeezing time reaches a preset time, detecting the compressed volume of the squeezed test sample; determining a soil looseness function based on the test soil moisture, initial volume, compressed volume and test resistance data of multiple test samples; determining the soil looseness suitability score based on the soil looseness function, the soil moisture, the resistance data, and the location of the test point.

[0038] According to one embodiment of the present invention, the looseness of soil is related to multiple aspects of soil, for example, the type of soil, the sand content of soil, soil moisture, whether soil is compressed by pressure, etc. The looseness of soil of a specific type of soil (the type of soil is determined and its sand content is determined) used for lily seedling cultivation can be described using a soil looseness function. Sampling can be performed in the soil of the lily seedling cultivation environment as a test sample, so that the looseness of the test sample under various humidity conditions is tested, thereby determining the looseness of the soil of this type under various conditions. Multiple sampling can be performed to obtain multiple test samples, and the humidity of some of the samples can be changed, for example, by spraying water mist on the test sample, or by water droplets to increase the soil moisture of the test sample, and the change amplitude of the soil moisture of different test samples is different from each other. After changing the soil moisture, the soil becomes more compact due to the increase in soil moisture, which may cause the gaps between soil particles to become smaller, thereby reducing the volume of the test sample and reducing the looseness. Furthermore, after the soil moisture of some test samples changes, the initial volume of each test sample can be measured without being squeezed (for example, the test sample is placed in a measuring cylinder to measure the initial volume), and the soil moisture can be tested. In addition, in this case, a probe can be used to insert each test sample. Since the change in soil moisture of some test samples causes the looseness of the soil to change, when the probe is inserted into different test samples at the same speed (i.e., the preset speed), the resistance it encounters is also different. This resistance can be used to describe the looseness of test samples with different moisture levels without being squeezed.

[0039] According to one embodiment of the present invention, in order to further test the looseness of each test sample, the same hydraulic equipment is used to squeeze each test sample according to the same preset force (for example, the piston of the hydraulic equipment is directly allowed to enter the above-mentioned measuring cylinder for squeezing, so that the compressed volume after squeezing can be directly measured after the squeezing is completed), and the time for which each test sample is squeezed is also the same. In other words, each test sample is squeezed in exactly the same way, so that the gaps between particles in the soil are further reduced and the looseness of the test sample is further reduced. After the squeezing is completed, a plurality of squeezed test samples are obtained, and the compressed volume of the squeezed test samples can be monitored.

[0040] According to one embodiment of the present invention, the difference between the initial volume before squeezing and the compressed volume after squeezing may indicate the looseness of the test sample before squeezing. The larger the difference between the two, the higher the looseness of the test sample before squeezing.

[0041] According to one embodiment of the present invention, a soil loosening function is determined based on test soil moisture, initial volume, compression volume and test resistance data of a plurality of test samples, including: determining an undetermined coefficient equation of the soil loosening function according to formula (3), (3), where is the initial volume of the test sample, is the compressed volume of the test sample, To test the soil moisture of the test sample, is the test resistance data at the kth moment in the insertion process, M is the number of moments in the insertion process, , , and are all undetermined coefficients, k≤M, and k and M are both positive integers; according to the test soil moisture, initial volume, compression volume and test resistance data of multiple test samples, the undetermined coefficients are solved to obtain the solution values ​​of the undetermined coefficients; according to the solution values ​​of the undetermined coefficients and the undetermined coefficient equations, the soil loosening function is obtained.

[0042] According to one embodiment of the present invention, in formula (3), It is the ratio between the initial volume and the compressed volume of the test sample. The larger the ratio is, the greater the difference between the initial volume and the compressed volume is, and the looseness of the test sample before compression is higher. Therefore, the ratio is inversely correlated with the test soil moisture, that is, the higher the test soil moisture is, the lower the looseness of the test sample before compression is. In addition, the ratio is also related to the average resistance of the probe at multiple moments during the insertion of the test sample. Inverse correlation, that is, the higher the looseness of the test sample before squeezing, the smaller the average resistance of the probe at multiple moments during the process of inserting the test sample. Based on the above analysis, an equation of undetermined coefficients can be set. Based on the inverse correlation between the average resistance and the test soil moisture and the looseness of the test sample before squeezing, the average resistance and the test soil moisture can be set in the denominator, and the undetermined coefficients can be used to calculate the average resistance and the test soil moisture. and As the coefficients of the two, we can also use the unknown coefficients As the unknown constant term in the denominator, and through the unknown coefficient As the residual term to be determined, the error in the fitting process is reduced.

[0043] According to one embodiment of the present invention, the data obtained during the test of multiple test samples can be used to solve the above four undetermined coefficients. Since there are four undetermined coefficients, the data obtained during the test of at least four test samples (test soil moisture, initial volume, compression volume and test resistance data) are required to solve the undetermined coefficients. If the number of test samples is more than four, the above undetermined coefficients can be solved by fitting to obtain the solution values ​​of the undetermined coefficients, and the solution values ​​of the undetermined coefficients are substituted into the above-mentioned undetermined coefficient equations to obtain a soil looseness function, so that in subsequent detection processes, the looseness of the soil can be determined by the soil moisture and the average resistance data of the probe, without the need to perform complex steps such as multiple sampling, squeezing, and detecting the data in the test process each time the looseness of the soil is detected. That is, the easily obtained soil moisture and resistance data are used to replace the data such as the compression volume and initial volume that need to be obtained through complex steps, and the looseness of the soil can be accurately represented.

[0044] In this way, the equation with unknown coefficients can be determined based on the relationship between the test soil moisture and the average resistance encountered at multiple moments during the process of inserting the probe into the test sample and the looseness of the test sample, thereby solving the soil looseness function. The soil looseness can then be represented by easily obtained soil moisture and resistance data and the calculation of the soil looseness function. There is no need to go through complicated steps to detect the soil looseness, thereby improving the convenience and accuracy of detecting the soil looseness.

[0045] According to one embodiment of the present invention, the soil looseness suitability score is determined according to the soil looseness function, the soil moisture, the resistance data, and the location of the test point, including: determining the distance between the test point and the placement position of the bulb used for lily seedling cultivation according to the location of the test point; determining the soil looseness suitability score according to formula (4). , (4), where is the radius of the preset lily growth range, is the distance between the tth test point and the location where the bulbs used for lily seedling cultivation are placed, is the soil moisture at the beginning of the current monitoring period, is the soil moisture at the end of the current monitoring period, is the resistance data of the probe at the t-th test point at the k-th moment during the insertion process, is the preset ratio, N is the number of test points, for The solution value of for The solution value of for The solution value of for The solution value of , t≤N, and t and N are both positive integers.

[0046] According to one embodiment of the present invention, in formula (4), Indicated in When , the conditional function value is 1, otherwise it is 0, where It means that the average soil moisture in the current monitoring period and the average resistance data of the probe at the t-th test point during the insertion process are substituted into the soil looseness function for calculation to obtain the soil looseness at the t-th test point. If the soil looseness at the t-th test point is greater than or equal to the preset ratio (for example, 1.2), it means that the soil looseness at the t-th test point meets the requirements, and its conditional function value is 1. Otherwise, it means that the soil looseness at the t-th test point is low and does not meet the requirements, and its conditional function value is 0.

[0047] According to one embodiment of the present invention, although the locations of the test points are all within the lily growth range (with the placement position of the bulbs used for lily seedling cultivation as the center and the As the radius of the circular range), but the distance between each test point and the placement of the bulb is different. After the lily seedlings take root, the time for the roots to reach the location of each test point is also different. Therefore, the importance of each test point is also different. For example, the root system arrives at the location of the test point closer to the placement location earlier, and the lily seedlings are less developed and more susceptible to the looseness of the soil (for example, it is more difficult to obtain nutrients and air in soil with low looseness, and it is also more difficult for the root system to develop further). Therefore, the importance of the test point closer to the location of the bulb is higher, and a higher weight can be set for it. In formula (4), it can be used As the weight of the conditional function corresponding to the t-th test point, the conditional functions of each test point are weighted summed. The ratio of the weighted summation result to the sum of the weights of each test point is solved to obtain the weighted average of the conditional functions of each test point, which can be used as the soil looseness suitability score and used to describe the suitability of the looseness of the soil for lily seedling cultivation. The higher the soil looseness suitability score, the more locations within the lily growth range that meet the soil looseness requirements, and the higher the importance of the locations with soil looseness requirements, the more conducive to lily seedling cultivation.

[0048] In this way, the soil looseness function can be used to determine whether the soil at each test point is loose enough to be suitable for lily seedling cultivation, and the importance of each test point can be determined based on the location of the test point, so as to obtain a soil looseness suitability score, which can accurately and objectively describe whether the looseness of the soil is suitable for lily seedling cultivation, thereby improving the convenience and accuracy of soil looseness detection and thus improving the success rate of seedling cultivation.

[0049] According to one embodiment of the present invention, the soil cultivation suitability score and the soil looseness suitability score may be weighted and summed to obtain the soil condition suitability score.

[0050] According to an embodiment of the present invention, in step S107, the external condition suitability score and the soil condition suitability score may be weighted and summed to determine the lily seedling environment suitability score, thereby accurately describing whether the overall environment for lily seedling cultivation is suitable.

[0051] According to an embodiment of the present invention, in step S108, it can be determined whether the suitability score of the lily seedling raising environment is lower than a threshold value (for example, 0.8). If it is lower than the threshold value, the lily seedling raising environment of the next monitoring cycle needs to be adjusted. When adjusting, it can be adjusted based on the external condition suitability score, the soil cultivation suitability score and the soil looseness suitability score respectively. For example, if the soil looseness suitability score is low, it can be determined first whether the average soil moisture is within the suitable humidity range. If the average soil moisture is within the suitable humidity range, the soil can be made looser by turning the soil. If the average soil moisture is higher than the upper limit of the suitable humidity range, the soil moisture can be reduced (for example, the amount of irrigation water can be reduced), and turning the soil can be performed. If the average soil moisture is lower than the lower limit of the humidity range, the soil moisture can be increased, and the soil can be made looser by turning the soil and drilling multiple pores in the soil. The present invention does not limit the specific method of adjusting the looseness of the soil.

[0052] According to the lily seedling environment control method of the embodiment of the present invention, the seedling environment when soil is used as the culture matrix can be monitored. In addition to monitoring the external environment such as temperature and light intensity, the soil breeding conditions can also be monitored based on data such as soil moisture, resistance data and fertilizer element content information, so that when the conditions are not suitable, they can be discovered in time and adjusted and controlled, thereby improving the breeding success rate using soil as the culture matrix, and it is easy to popularize and produce. When determining the external condition suitability score, the temperature suitability of the lily seedling environment can be determined by counting the total number of moments belonging to the suitable temperature range in the current monitoring cycle and the ratio of the number of moments, and the light suitability of the lily seedling environment can be determined by counting the total number of moments in the current monitoring cycle that belong to the suitable light intensity range and the relative deviation between the number of moments corresponding to the suitable light duration, thereby determining the external condition suitability score, so that the external condition suitability score can accurately and objectively describe the suitability of the external conditions of the lily seedling environment. When determining the soil suitability score for cultivation, the conditional function can be used to determine whether the average content information of nutrients such as water content and various fertilizer elements in the soil is within the appropriate content range to solve the soil suitability score for cultivation, thereby accurately describing whether the nutrients contained in the soil are suitable for lily seedling cultivation through the soil suitability score for cultivation, and improving the accuracy and objectivity of the soil suitability score for cultivation. When determining the soil looseness function, the equation for the undetermined coefficient can be determined based on the relationship between the average resistance at multiple moments during the test soil moisture and the insertion of the probe into the test sample and the looseness of the test sample, thereby solving the soil looseness function, and then the soil looseness can be represented by easily obtained soil moisture and resistance data, as well as the calculation of the soil looseness function, without the need to detect the soil looseness through complex steps, thereby improving the convenience and accuracy of detecting the soil looseness. When determining the soil looseness suitability score, the soil looseness function can be used to determine whether the soil at each test point is loose enough to be suitable for lily seedling cultivation, and the importance of each test point can be determined based on the location of the test point, thereby obtaining a soil looseness suitability score to accurately and objectively describe whether the soil looseness is suitable for lily seedling cultivation, thereby improving the convenience and accuracy of soil looseness detection and thus improving the success rate of seedling cultivation.
