Description

Technical Field

[0001] This application belongs to the technical field of protected agriculture. Specifically, it relates to a method for improving protected agriculture soil based on biostimulants. Background Art

[0002] In the improvement of saline-alkali land, protected agriculture technology has been widely adopted. On the basis of realizing the improvement of saline-alkali land soil, certain economic benefits are obtained to achieve two-way development. Due to the particularity of protected agriculture, isolation protection of the area and regional application of drugs can be realized, which improves the utilization rate of drugs and resources to a certain extent. However, this also puts forward new requirements for the types of drugs and the drug application plan. In the current development of protected agriculture, especially in the development of protected agriculture in saline-alkali areas, biostimulants have been introduced to adjust the growth state of crops. However, on the one hand, the application of biostimulants relies too much on experience, resulting in a mismatch between the amount of drugs used and the needs of crops, and the effect of fully improving the utilization rate of biostimulants cannot be achieved. On the other hand, in the adjustment and use of biostimulants, even if only one area needs to be formulated, a biostimulant mixture with a unified formula is often used for all areas in the entire protected agriculture. This is likely to cause the planted crops in other normal growth areas to be unable to adapt to the new biostimulant formula, resulting in a negative impact on their growth state. The above two aspects will make it difficult for biostimulants to play their due role in soil improvement in the implementation of protected agriculture technology, and it is even more difficult to improve the growth quality of planted crops based on soil improvement work.

[0003] Therefore, how to reasonably adjust and apply biostimulants to achieve reasonable improvement of the soil in protected agriculture areas is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

Thus, only the biostimulants in the improved areas are adjusted, and the other areas are not adjusted. Moreover, for the improved areas in different regions, personalized biostimulant application is carried out for all areas, achieving personalized soil improvement. Brief Description of the Drawings

[0017] To more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for use in the embodiments of the present application or the prior art. Obviously, the following descriptions are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings. The drawings are used to provide a further understanding of the present disclosure and constitute a part of the specification. Together with the following specific embodiments, they are used to explain the present disclosure, but do not constitute a limitation to the present disclosure. In the drawings: Figure 1 It is a flowchart of a facility agriculture soil improvement method based on biostimulants provided by an embodiment of the present application; Figure 2 It is a schematic diagram of the soil improvement areas of a facility agriculture soil improvement method based on biostimulants provided by an embodiment of the present application; Figure 3 It is a schematic diagram of the control of the biostimulant application areas of a facility agriculture soil improvement method based on biostimulants provided by an embodiment of the present application. Detailed Embodiments

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. Additionally, in the embodiments of the present application, "first", "second", etc. are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0019] In the work of saline-alkali land improvement, facility agriculture technologies have been widely promoted, such as greenhouses, drip irrigation, etc. In the field of facility agriculture technologies, it is supported to apply various drugs, especially biostimulants, to saline-alkali areas based on existing agricultural facilities. However, there is a widespread problem at present. On the one hand, the accuracy of formula adjustment of biostimulants is insufficient, or even formula adjustment is not carried out, and biostimulants are directly configured based on the experience of technicians. This leads to a large deviation between the actual needs and the applied biostimulants during different growth cycles of the planted crops, resulting in poor use effects of biostimulants. On the other hand, the agricultural facilities used are often for the entire area. After the adjustment of biostimulants, it is a plan to adjust all the planted crops. This leads to the adjustment effect that although good adjustment effects are achieved for the poorly growing planted crops, the crops growing normally in other areas are also adjusted, which instead makes their growth poor. These two aspects will both lead to a decline in the growth quality of the planted crops. Especially in saline-alkali land improvement, the planted crops need to play a role in saline-alkali land improvement. Under the combined action of these two problems, due to the poor growth of the planted crops, the quality of the saline-alkali land improvement work will ultimately decline.

[0020] To solve the problems of the prior art, the present application discloses a method for improving facility agriculture soil based on biostimulants, as Figure 1 shown in the flowchart of a method for improving facility agriculture soil based on biostimulants provided by an embodiment of the present application. Specifically: S110. Obtain the planted crops in the coverage area of facility agriculture and establish a biostimulant demand table for different growth stages of the planted crops.

[0021] S120. Obtain the growth state of the planted crops. If it does not meet the preset growth state standard, obtain the planted crops with poor growth.

[0022] S130. Obtain the concentrated distribution area of the planted crops with poor growth to obtain a cluster of poorly growing crops.

[0023] S140. Obtain the number of plants in the cluster of poorly growing crops. If it is not less than the preset number of plants, obtain the soil improvement area.

[0024] S150. Based on the growth state of the planted crops and the biostimulant demand table in the soil improvement area, obtain the biostimulant deviation amount.

[0025] S160. Based on the biostimulant deviation amount, obtain the biostimulant formula for soil improvement to obtain an improved formula.

[0026] S170. Based on the improved formula, apply biostimulants to the soil improvement area.

[0027] The purpose of all the above steps is to reasonably adjust the formula of the growth stimulant, accurately determine the areas of the soil that need to be improved, and then make corresponding adjustments to the soil in the areas to be improved, so as to achieve personalized adjustment for each area and improve the effect of soil improvement.

[0028] Next, the specific content of all the above steps will be described in detail. Specifically: As described in step S110, the purpose of this step is to determine the planted crops, then analyze their requirements for the biostimulant, and at the same time determine the performance of the planted crops when the application amount of the biostimulant is unreasonable, laying a foundation for the subsequent analysis of the biostimulant requirements of the planted crops. Specifically: S111. Obtain the varieties of planted crops within the coverage area of protected agriculture.

[0029] The purpose of this step is to specifically determine the requirements for the biostimulant based on the determined varieties of planted crops.

[0030] Among them, by determining the varieties of crops planted in this area, the requirements for the biostimulant at different growth stages can be obtained.

[0031] In some embodiments, based on the soil and environmental performance of this area, the varieties of planted crops are determined, and then the varieties of planted crops are directly obtained.

[0032] S112. Obtain the requirements for the biostimulant of the planted crop varieties at different growth stages.

[0033] The purpose of this step is to, when the requirements for the growth stimulant at different stages are determined, in the subsequent growth state analysis, based on this index, determine and effectively solve the total amount problem of the biostimulant applied in the current growth stage.

[0034] Among them, obtain the requirements for the biostimulant of the crop varieties in different growth cycles.

[0035] Among them, it is also necessary to determine the types of requirements for the biostimulant of the crop varieties in different growth cycles.

[0036] Among them, for each type of requirement for the biostimulant, it needs to be determined separately.

[0037] Among them, for the requirement amount, it can be described based on indicators such as the concentration of the biostimulant and the weight of the active ingredient, and this application does not make any limitations.

[0038] S113. Based on the requirements for the biostimulant and the time nodes of the growth stages, obtain the application amount of the growth stimulant at the time nodes.

[0039] The purpose of this step is to obtain the application amount of the biostimulant based on the time node, so that in the subsequent adjustment and application of the biostimulant formula, based on the recorded time node parameters, the deviation amount of the biostimulant can be determined based on the time node.

[0040] Among them, for the determined planted crop, determine the occurrence time of each growth cycle after crop cultivation.

[0041] Among them, for each growth cycle, determine how long it takes to reach the corresponding growth state and the starting time point of the growth cycle under crop planting, so as to establish the corresponding relationship between the growth cycle and the corresponding growth time.

[0042] Among them, establish a corresponding relationship between the growth cycle and the growth time, so as to obtain the corresponding relationship between the growth cycle and the growth.

[0043] S114. When the application amount of the growth stimulant does not match the requirements of the cultivated crop, obtain the growth state of the planted crop to obtain a poor growth performance.

[0044] The purpose of this step is that in the growth of the planted crop, whether the biostimulant applied to the planted crop is higher or lower than the crop requirements, it will have a negative impact on the growth of the planted crop. In order to facilitate the determination of problems with the application amount of the growth stimulant in the future, it is necessary to determine the poor growth performance when there is a mismatch.

[0045] Among them, based on the existing crop planting experiences and knowledge, determine the performance of the planted crop when it grows poorly, and determine the association between this performance and the biostimulant.

[0046] Among them, for the poor growth performance, the specific performances set include all the poor growth performance situations such as leaf shedding of the plant, short plant height, and withered and yellow plant leaves.

[0047] Among them, for all the poor growth performances, it is necessary to establish the association between the current performance and the poor growth performance. For example: short plant height corresponds to too low an application amount of auxin, and early withering and / or leaf shedding of the leaves indicates too much abscisic acid application amount, etc.

[0048] In some embodiments, for each type of poor growth performance, quantitatively describe the poor growth performance, and for each quantitative description, set the corresponding biostimulant addition amount parameter, so as to establish the corresponding relationship between the biostimulant addition amount and the quantitative performance of the growth state.

[0049] S115. Establish the correspondence between the application rate of biostimulants, normal growth performance, poor growth performance, and time nodes, and obtain the growth stimulant demand table.

[0050] The purpose of this step is that for planted crops, by establishing the growth stimulant demand table, in the subsequent adjustment of the growth stimulant formula, the problems of the growth stimulants input during the growth of the current planted crops can be directly queried based on this demand table.

[0051] Among them, for the application rate of growth stimulants, poor growth performance, and growth time nodes of planted crops, one-to-one correspondences are established among them, so as to establish the growth information correspondence for all factors among them.

[0052] Among them, in the establishment of the growth stimulant demand table, based on the growth time of the planted crops generated therein, the growth time nodes can be used as the basic time points, thus forming: growth time - application rate of growth stimulants - normal growth performance - poor growth performance when the application rate of biostimulants does not meet the index. The result obtained is the growth stimulant demand table.

[0053] Among them, there can be various corresponding forms of poor growth performance when the application rate of biostimulants does not meet the index. For each poor growth performance, it needs to be included in this growth stimulant demand table.

[0054] As described in step S120, the purpose of this step is to identify the growth status of the planted crops in the current entire area and determine the planted crops with poor growth from them, thereby laying a foundation for the determination of the soil improvement area. Specifically: S121. Obtain the images of the planted crops to get the crop images.

[0055] The purpose of this step is to directly obtain the growth images of the planted crops. Based on the method of image recognition, all information such as the height of the planted crop plants, the color of the leaves, and the number of leaves can be directly obtained to reduce the analysis difficulty of the plant performance.

[0056] Among them, in the facility agriculture system, multiple cameras are set up, and each camera uses a rotating scanning method to obtain the plant images within the space it can scan.

[0057] Among them, during the shooting of the crops, it is necessary to ensure that the set cameras can cover the entire perspective of all areas within the entire land range to achieve the determination of the growth status of all plants.

[0058] Among them, during the process of obtaining images of planted crops, the obtained images should be selectively processed. For the acquired images, frame images are also obtained, and these frame images are also used as crop images.

[0059] S122. Preprocess the crop image to obtain a preprocessed image.

[0060] The purpose of this step is that through the preprocessing of the crop image, the shape of the currently photographed planted crop can be better recognized, so as to directly determine the growth status of the crop based on this image.

[0061] Among them, considering that biostimulants may cause changes in the color of crops, in specific processing, gray-scale processing cannot be performed during preprocessing, but the color needs to be maintained.

[0062] Among them, the main image preprocessing methods include methods such as enhancing contrast, screening out individual plants from the population based on the leaf edge line, and increasing brightness, which are not limited in this application.

[0063] Among them, for the preprocessing measures, it also includes zooming in and out of the image to ensure that in the subsequent analysis of the growth status performance, the plants in the image can be directly compared with the plants in the growth stimulant requirement table.

[0064] S123. Based on the preprocessed image, obtain the growth status performance of the planted crop.

[0065] The purpose of this step is that after obtaining the preprocessed image, directly based on the adopted preprocessed image, analyze the growth status performance of the planted crop, so as to determine the growth problems of the planted crop.

[0066] Among them, after obtaining the preprocessed image, directly compare the plant growth status shown in this image with the normal growth performance in the biostimulant requirement table to determine whether the current planted crop is in a normal growth state.

[0067] In some embodiments, for the actual performance of the planted crop, it is directly compared with the poor growth state. When it is found that the characteristics of the obtained plant image match the poor growth state, it is considered that the current planted crop plant shows a poor growth state.

[0068] In some embodiments, when the preprocessed image is obtained, the state of the plants in the image is directly described, including plant height, number of leaves, leaf color, etc. For example: Plant 112 - 32 cm - 24 - light yellow (56%), light green (26%), dark green (18%), which means: the plant number is 112, the plant height is 32 cm, the number of leaves is 24, and the color performance is that the area ratio of light yellow is 56%, the area ratio of light green is 26%, and the area ratio of dark green is 18%.

[0069] Among them, for all the obtained performance data, they are compared with the relevant parameters in the set normal growth state or poor growth state. In this case, data intervals are set for the performance data in the biological stimulant demand table. When the actually detected value falls into the corresponding data interval, it is considered that the currently obtained crop image corresponds to the normal growth state or the poor growth state.

[0070] S124. Compare all the growth state performances with the normal growth state performance or the poor growth performance of the planted crops. If any one of the growth state performances does not conform to the corresponding normal growth state, then the planted crop is a poorly growing planted crop.

[0071] The purpose of this step is to determine the poorly growing planted crops that can be monitored currently after obtaining the growth state performance of the planted crops.

[0072] Among them, the growth state performance of the obtained planted crops is represented with the information in the growth stimulant demand table.

[0073] Among them, compare the growth state performance with the obtained normal growth state performance or the poor growth performance, and determine the growth problems existing in the plant in the obtained image information.

[0074] Among them, if any one of the growth state performances of the obtained plants does not conform to the normal growth state, or any one of the growth state performances conforms to the poor growth performance, then the plant needs to be determined as a poorly growing planted crop.

[0075] As described in step S130, the purpose of this step is to, based on the obtained poorly growing planted crops, determine the cluster of poorly growing crops existing in the space where they are located, so that the soil improvement area can be determined based on this cluster. Specifically: S131. Obtain the positions of the poorly growing planted crops to obtain the coordinates of the poorly growing crops.

[0076] The purpose of this step is that after determining the positions of the poorly growing planted crops and expressing them in coordinates, it is easier to determine the adjacent plants, so as to find the adjacent plants of the poorly growing planted crops.

[0077] Among them, after obtaining the poorly growing planted crops, the crop positions can be directly determined based on the images or the labels of the plants.

[0078] Among them, for the obtained plant positions, they are directly quantitatively expressed based on the set coordinate system. The determination of the coordinate system is not limited in this application.

[0079] In some embodiments, it is not necessary to determine the positions of the poorly growing planted crops, and only the association relationship needs to be established based on the plant labels and the corresponding coordinates.

[0080] S132. Based on the coordinates of the poorly growing crops, obtain the growth states of the adjacent planted crops to obtain the growth states of the first adjacent plants.

[0081] The purpose of this step is that in some cases, the poor growth state of the plants is not caused by the unreasonable application amount of the biostimulant in the whole area, but due to the combined action of various factors, resulting in only one or a few plants growing poorly. This reason is mostly caused by accidental reasons. Therefore, in order to determine the soil improvement area, it is necessary to determine the growth states of the plants at the adjacent coordinates after finding the coordinates of the poorly growing crops.

[0082] Among them, based on the coordinates of the poorly growing crops, determine their adjacent plants. For example, if the coordinates are found to be (3, 5), the coordinates of the adjacent plants are (2, 5), (3, 4), (3, 6), and (4, 5).

[0083] In some embodiments, the plants at 8 coordinates within the square range around the coordinates of the poorly growing crops can also be determined as adjacent plants with the coordinates of the poorly growing crops as the center.

[0084] Among them, the adjacent plants directly adjacent to the poorly growing planted crops are determined as the first adjacent plants.

[0085] Among them, determine the growth states of all the first adjacent plants. The specific method for determining the growth states is the same as the content in steps S121 - S123, and will not be elaborated here.

[0086] S133. Compare the growth states of the first adjacent plants with the preset growth state standard to obtain the first adjacent plants with poor growth.

[0087] The purpose of this step is to determine whether the poorly growing planted crops found exist independently. If not, analyze the growth conditions of the surrounding cultivated crops, identify adjacent poorly growing planted crops, and obtain the soil improvement scope. If so, this area is not considered an area where the biostimulant formula needs to be adjusted.

[0088] Among them, the method for comparing the growth status is the same as that in step S124 and will not be elaborated here.

[0089] Among them, the preset growth status standard in this step is the normal growth status performance or the poorly growing performance.

[0090] S134. Obtain the growth status of the adjacent plants of the first adjacent plant with poor growth to obtain the growth status of the second adjacent plants.

[0091] The purpose of this step is to, after discovering the growth status of the first adjacent plant, take this plant as a reference to obtain the growth status of its adjacent plants.

[0092] Among them, the method of this step is the same as that of step S132 and will not be elaborated here.

[0093] S135. Compare the growth status of the second adjacent plants with the preset growth status standard to obtain the second adjacent plants with poor growth.

[0094] The purpose of this step is to analyze the growth status of the second adjacent plants to determine whether there are planted crops with poor growth among the currently obtained second adjacent plants.

[0095] Among them, the method of this step is the same as that of S133 and will not be elaborated here.

[0096] S136. Obtain the growth status of the adjacent plants of all the planted crops with poor growth until the adjacent plants meet the preset growth status standard.

[0097] The purpose of this step is to determine all the obtained planted crops with poor growth to determine the edge of the planted crops with poor growth in the entire area.

[0098] Among them, when it is found that the growth status of the adjacent plants of a certain planted crop with poor growth is in a normal state, it is considered that this planted crop with poor growth is the outermost planted crop with poor growth in the entire area.

[0099] Among them, in order to avoid repetitive problems in analyzing the growth status of plants, after discovering a planted crop with poor growth, mark this plant, and in subsequent analyses of the growth status of adjacent plants, do not analyze the growth status of the already marked plants.

[0100] In some embodiments, other methods can also be adopted to avoid duplicate analysis work, and the present application does not limit this technical solution.

[0101] S137. Configure all the poorly growing planted crops into the same group of planted crops to obtain a cluster of poorly growing crops.

[0102] The purpose of this step is that for all the obtained poorly growing planted crops, their worlds need to be set in the same group of planted crops. Then, in subsequent operations, the areas that need soil improvement can be determined based on the distribution positions of this cluster.

[0103] Among them, determine the areas of all the poorly growing planted crops among them, and set all the plants included in this area as a cluster of poorly growing crops.

[0104] Among them, for the poorly growing planted crops in this cluster of poorly growing crops, determine the outermost poorly growing plants among them and connect them. The planted crops within the coverage area of this connection are the cluster of poorly growing crops.

[0105] In some embodiments, the number of plants of the poorly growing planted crops and the plant coordinates can also be directly recorded. Then, based on these two parameters, the distribution position of the cluster of poorly growing crops is obtained. After that, the areas for soil improvement are determined based on this range.

[0106] Among them, as Figure 2 shown, it is a schematic diagram of the area for soil improvement of a method for soil improvement in protected agriculture based on biostimulants provided by an embodiment of the present application. Specifically, as Figure 2 shown in (a), the dotted line part is the planting area of all the planted crops, and all the small rectangular areas inside are the plots of each cluster of planted crops. Among them, the "×" inside represents the planted crops in the normal growth state, and the "○" represents the poorly growing planted crops. Among them, the "○" numbered 1 represents the position of the first poorly growing crop. Through the analysis of it, the cluster of poorly growing crops in the entire area can be determined, and the area where this cluster is located is the area for soil optimization.

[0107] As described in step S140, the purpose of this step is that on the one hand, the positions for soil improvement can be directly obtained based on the cluster of poorly growing crops, and on the other hand, it can be determined whether the current poor growth of the crops is caused by accidental factors even if there is a clustering performance of the poorly growing crops, so as to accurately determine the areas for soil improvement. Specifically: S141. Obtain the number of planted crops in the cluster of poorly growing crops to get the number of plants.

[0108] The purpose of not being able to cover is that in the analysis of the cluster scale, the parameter that can most reflect the cluster scale is obviously the number of plants. Therefore, in the processing, after obtaining the number of plants, it can be used for the subsequent cluster scale judgment process.

[0109] Among them, analyze the number of medium crops in the entire poor crop cluster and count the number of poorly growing planted crops among them.

[0110] In some embodiments, directly obtain the number of coordinate points of the poorly growing planted crops in the poor crop cluster, and this number is the number of plants.

[0111] S142. Compare the number of plants with the preset number of plants. If it is not less than the preset number of plants, obtain the outermost poorly growing planted crops in the poorly growing crop cluster.

[0112] The purpose of this step is that the ultimate purpose of this application is to adjust the biostimulant in the land area to achieve the purpose of personalized soil improvement. Therefore, in the processing, it is also necessary to determine the soil improvement area based on the distribution location of the poorly growing cluster. By determining the outermost poorly growing crops in the poorly growing crop cluster, the outermost planted crops in the soil improvement area can be determined.

[0113] Among them, obtain the outermost poorly growing planted crops in the poorly growing crop cluster and connect them.

[0114] In some embodiments, in the poorly growing crop cluster, obtain the coordinates of each poorly growing planted crop, and just obtain the outermost coordinates. The planted crop corresponding to this coordinate point is the outermost poorly growing planted crop.

[0115] Among them, for all the obtained outermost poorly growing planted crops, just connect their coordinates.

[0116] S143. Obtain the biostimulant absorption range of the outermost poorly growing planted crops to obtain the outer edge of the absorption range.

[0117] The purpose of this step is to consider that the absorption range of the planted crops for the applied biostimulant is likely to be larger than the plant coverage range in the soil. Therefore, it is also necessary to determine the edge of the absorption range to lay a foundation for the subsequent soil improvement range.

[0118] Among them, the determination of the absorption range edge can be based on the root coverage range of the planted crops.

[0119] In some embodiments, use the agricultural facilities adjacent to the outside of the outer edge of the poorly growing planted crops as the biostimulant absorption range, and the obtained result is the outer edge of the absorption range.

[0120] In some embodiments, it can also be determined based on the coverage range of the plant, wherein the projection of the coverage range of the plant on the ground is the outer edge of the absorption range.

[0121] S144. Connect the outer edges of all the absorption ranges to obtain the soil improvement area.

[0122] The purpose of this step is that in the analysis of the soil improvement area, since the planted crops will absorb the biostimulants in the soil, connecting the outer edges of all the absorption ranges, the corresponding area is the soil improvement area.

[0123] Among them, for the connected line of the obtained absorption outer edges, directly based on the intersection or tangency points of the outer edges of the absorption range, connect the outer intersection points to obtain the soil improvement area.

[0124] In some embodiments, for the obtained outer edge of the absorption range, since there are multiple planted crop plants with poor growth at the outermost edge, a rectangle with the maximum length and width can be established based on the maximum value of all the outermost edges, and the soil area included in this rectangle is the soil improvement area.

[0125] In some embodiments, if the biostimulant absorption range is determined based on the coverage range of the plant, then in the drawing of the connected line of the outer edge of the absorption range, connect the lines based on the projected area on the ground to obtain the soil improvement area.

[0126] In some embodiments, connect the lines based on the positions or coordinates of the planted crops with poor growth at the outermost edge to obtain the plant coverage range, and then integrate the area of the biostimulant absorption range into this plant coverage range to obtain the soil improvement area.

[0127] It should be noted that in the facility agriculture system, among the soil improvement areas obtained in all the above steps, although the plants all show poor growth, it is very likely that the planted crops with poor growth in two or more of these areas are caused by unreasonable application amounts of different biostimulants. Obviously, for this situation, only applying a biostimulant mixture with the same formula in this area cannot ensure that the soil in the entire area has been correctly improved. Therefore, in order to improve the improvement effect, it is also necessary to determine the areas with poor growth caused by unreasonable application of biostimulants in the soil improvement area, so as to further adjust the soil improvement area. Specifically: S145. Obtain the growth states of all the planted crops with poor growth in the soil improvement area to obtain the state of each plant in the area.

[0128] The purpose of this step is to lay a foundation for determining the demand deviation of biostimulants required for all plants by determining the growth status of all poorly growing planted crops in the soil improvement area.

[0129] Among them, obtain images of all plants in the entire soil improvement area and establish each individual image.

[0130] Among them, for each individual image of a plant, determine the plant status. The specific determination method and steps S121 - S123 are the same and will not be elaborated here.

[0131] S146. Compare the status of each plant in the area with the preset growth status standard to obtain the defects of poorly growing cultivated crops.

[0132] The purpose of this step is to compare the specific plant status with the preset growth status standard that has been set, so as to determine different status performances and thus determine the association between this status performance and the incorrect application amount of biostimulants.

[0133] Among them, for the defects of poorly growing cultivated crops, for the preset growth status standard, it can be directly set based on the established biostimulant demand table.

[0134] Among them, for the confirmation of all defects of poorly growing cultivated crops, the method is the same as that in step S124 and will not be elaborated here.

[0135] S147. Obtain the aggregation space of the poorly growing planted crops with the same defects of the poorly growing cultivated crops. Among the divided areas of the soil improvement area, the poorly growing planted crops have the same defects of the poorly growing cultivated crops.

[0136] The purpose of this step is to determine the aggregation space of all types of poorly growing cultivated crops. After that, based on this aggregation space, the soil improvement area can be further adjusted.

[0137] Among them, determine the status of all plants therein and identify the specific performance of this plant status.

[0138] Among them, mark the specific performance of the plant status and determine the location of plants with the same poorly growing performance.

[0139] Among them, determine whether the plants marked with the poorly growing performance are adjacent. If adjacent, set these two plants in the same aggregation space.

[0140] Among them, it is necessary to ensure that all plants with the same poor growth performance within the same aggregation space must be adjacent, and delimit the aggregation space, so as to further divide the soil improvement area.

[0141] S148. Based on the aggregation space, divide the soil improvement area to obtain the divided area of the soil improvement area.

[0142] The purpose of this step is to directly divide the aggregation space of all planted crops with the same poor growth state, so as to obtain the divided area of the soil improvement area.

[0143] Among them, obtain the outermost planted crops of the planted crops with the same poor growth state for area division.

[0144] In some embodiments, obtain the coordinates of the planted crops with the same poor growth state, and then connect the coordinates to obtain the edge of the aggregation space within the soil improvement area.

[0145] In some embodiments, the method for determining the divided area is similar to step S137. It is necessary to delimit the absorption range of the biostimulant therein and then perform area division.

[0146] In some embodiments, considering that the absorption ranges of two different planted crops with poor growth states may have an intersection area, for the division methods of these two and multiple aggregation holes, the obtained intersection points can be directly connected, and the enclosed space obtained after connection is the aggregation space. It should be noted that for all the planted crops with poor growth in each aggregation space, the poor growth performance of the plants therein must be the same.

[0147] Among them, as Figure 2 shown in (b), among them, the poor growth performances in the left and right regions are different, and based on the poor growth performances in the two obtained regions, the soil optimization area is further decomposed to obtain the area division result.

[0148] As described in step S150, the purpose of this step is to determine the problem of the biostimulant to be applied to the currently obtained planted crops with poor growth, and then based on this problem, adjust the formula of the biostimulant. Specifically: S151. Obtain the growth state of the planted crops in the soil improvement area to obtain the plant performance.

[0149] The purpose of this step is that for the soil improvement area where the planted crops are all in a poor growth state and their growth states are the same, which means that all the crops in this area have the same problem of the application rate of biostimulants. Therefore, in order to determine the problem of biostimulant application, it is necessary to further analyze the plant performance.

[0150] Among them, for the plant performance, all the performance data that can be collected need to be obtained, including plant height, number of leaves, number of fruits, number of flowers, leaf color, etc.

[0151] Among them, for all the plant performances, they need to be recorded, and all the parameters are used as the basis for the subsequent judgment process.

[0152] In some embodiments, the mean values of all the performance data are calculated respectively to obtain the normalization result.

[0153] S152. Compare the obtained plant performance with the poor growth performance in the biostimulant requirement table to obtain the application rate of growth stimulants.

[0154] The purpose of this step is that for all the obtained plant performance parameters, they need to be compared with the corresponding poor growth performance, and then the relationship between each poor growth performance and the application rate of biostimulants can be determined to identify the problems existing in the current biostimulant application.

[0155] Among them, in the biostimulant requirement table, the poor growth performance corresponding to the unreasonable application rate of biostimulants has been set for comparison. For example: during the filling period of a certain crop, it is found that the leaves turn yellow and wither. At this time, the biostimulant requirement table states the degree of leaf yellowing and withering for different concentrations of abscisic acid application, and then the deviation amount of the current abscisic acid application rate is directly determined based on this performance.

[0156] Among them, for all the performances of the planted crops caused by the deviation of the application rate of growth stimulants, all the generated performances need to be compared with the corresponding poor growth performance. That is to say, it is necessary to compare all the growth performances on the plants separately to determine whether the current growth state performance of the planted crops is caused by the application problems of multiple biostimulants in the current biostimulant application.

[0157] In some embodiments, for each performance state of the plant, the mean value is calculated, and then the mean value is directly compared with the poor growth performance to determine the current application rate of biostimulants.

[0158] Among them, for the case where the mean is not calculated, each plant is compared, and the amount of biostimulant applied to the planted crops in this area is determined, and then the mean is calculated.

[0159] S153. Obtain the difference between the growth stimulant application amount and the requirements of the cultivated crops to obtain the growth stimulant deviation amount.

[0160] The purpose of this step is that based on the determination of the deviation amount, in subsequent formula adjustments, according to the size of the deviation amount, the increase or decrease amounts of all substances in the corresponding growth stimulant formula can be adjusted accordingly, and the biostimulant application ratio in the formula can be set.

[0161] Among them, for the actually obtained biostimulant application amount, the deviation amount can be obtained by directly calculating the difference from the normal biostimulant content in the biostimulant requirement table.

[0162] As described in step S160, the purpose of this step is that after it has been determined that the planted crops have the same growth state problems and the deviation amount has been determined, for this deviation amount, the biostimulant formula needs to be improved, and then the growth state of the planted crops can be adjusted based on this improved formula. Specifically: S161. Based on the growth state of the planted crops, obtain the types of various biostimulants applied to the soil improvement area.

[0163] The purpose of this step is that for the growth state of the planted crops that has been obtained, the unreasonable biostimulant application types in the current crop growth can already be known, and then the biostimulant can be adjusted accordingly, that is, the adjustment type of the biostimulant is obtained.

[0164] Among them, according to the growth state of the planted crops and the comparison result with the biostimulant requirement table, the unreasonable application amount types of the biostimulant are determined.

[0165] Among them, for the obtained biostimulant types, according to the comparison results, the biostimulant types that need to be adjusted subsequently are marked.

[0166] S162. Based on the biostimulant deviation amount, obtain the weights of the active ingredients of various biostimulants applied to the soil improvement area.

[0167] The purpose of this step is that in the determination of the biostimulant deviation amount, the possible deviation amounts include concentration, proportion of active ingredients, weight of active ingredients, etc. In any case, a standard needs to be set. Among them, the determination of the weight of the active ingredient is obviously the best way to determine the standard.

[0168] Among them, in the determination of the concentration deviation amount, based on the concentration difference, the weight value of the active ingredient currently put is directly determined.

[0169] Among them, if it is determined based on the weight of the active ingredient, the difference can be directly calculated.

[0170] Among them, for other deviation amounts, the weight of the active ingredient can be determined according to the corresponding processing methods.

[0171] S163. Obtain the application amount of the biostimulant based on the weight of the active ingredient of each type of biostimulant and the concentration of the active ingredient of each type of biostimulant.

[0172] The purpose of this step is that for the biostimulants that need to be adjusted, the application amount of the biostimulants that need to be adjusted needs to be processed according to their types and the weight of the active ingredient that has been obtained. It should be noted that this application is processed based on objects such as solutions and aerosols of biostimulants, and in the application of biostimulants, it may be necessary to apply based on a mixture. In this case, the application amount of the biostimulant therein refers to the determination of the application amount to objects such as solutions or aerosols.

[0173] Among them, for the processing of the application amount, it can be directly determined based on the concentration of the raw material.

[0174] Among them, the concentration of the raw material is significantly higher than the concentration of the active ingredient in the biostimulant that needs to be actually applied.

[0175] Among them, in the preparation of the mixture, it is necessary to screen and determine the concentration of the biostimulant with the highest requirement for the concentration of the biostimulant by the planted crops.

[0176] Among them, in the case of a biostimulant mixture, it is necessary to determine the concentration of the raw materials of all the biostimulants that need to be applied, and then determine the concentration of each biostimulant. The equation is: ; Among them, represents the concentration of the i th biostimulant, represents the application amount of the i th biostimulant, i represents the category index of the biostimulant, j represents the total amount of the category index of the biostimulant, represents the iThe concentration deviation of a biological stimulant. For this step, its function is to compare the concentrations of all the obtained biological stimulants with the concentration of the correctly dispensed biological stimulant. That is to say, Equation (1) is an equation for verification. If it is found that the concentration of one of the biological stimulants is different from the correctly dispensed concentration, the weight parameter therein needs to be adjusted accordingly.

[0177] Among them, for all biological stimulants, it is necessary to calculate their concentrations to obtain the application amount of the finally dispensed biological stimulant.

[0178] Among them, for the obtained application amount, its calculation equation is: ; Among them, represents the application amount of the raw material of the i th biological stimulant, represents the raw material concentration of the i th biological stimulant.

[0179] Among them, for the concentration of the i th biological stimulant obtained, the calculation result is obtained, and the effective ingredient concentration of each biological stimulant and the required application amount are respectively analyzed to obtain various concentration results therein.

[0180] Among them, when it is found that the effective ingredient concentration therein does not meet the requirements, the formula needs to be further adjusted.

[0181] S154. Obtain the application amounts of all the biological stimulants, and obtain the effective ingredient concentrations of all the biological stimulants in the biological stimulant mixture to obtain an improved formula.

[0182] The purpose of this step is that for the effective ingredient concentration of the biological stimulant, there may be a situation where the concentration of a certain biological stimulant does not meet the application amount requirements. In order to ensure to the greatest extent that the concentrations of all biological stimulants meet the requirements of the effective ingredient concentration, the formula needs to be further adjusted.

[0183] Among them, for determining the types of various biological stimulants and the weights of the effective ingredients, corresponding treatments are all carried out. Among them, it is necessary to determine the proportion of the weights of all the effective ingredients, so as to obtain the application proportions of various biological stimulants in the formula. The specific calculation equation is: ; Among them, represents the weight of the effective ingredient in the application amount of the p th biological stimulant, p represents the effective ingredient weight index in the application amount of the biological stimulant, qRepresents the total weight index of the active ingredients in the application amount of the biostimulant, Represents the p proportion of the active ingredients in the application amount of the

[0184] th biostimulant. Among them, it is necessary to obtain the proportion of the application amount of each biostimulant, and its calculation equation is: ; Among them, represents the p weight of the application amount of the

[0185] th biostimulant. Among them, after considering the proportion of the active ingredients, the raw material application amount of each type of biostimulant is obtained, and its equation is: ; Among them, in this equation and in equation (2) are exactly the same, only the label indexes are replaced. The meaning of this equation is that for each biostimulant, the raw material application weight of the biostimulant is determined based on the weight.

[0186] Among them, after determining each raw material application amount parameter, it is configured based on the application amount.

[0187] Among them, when it is found that after the application amount configuration, the concentration of the active ingredients of the biostimulant in it does not meet the correct application standard, water resources are added to the mixture. Among them, equation (1) is modified to: ; Among them, represents the quality of the added water resources.

[0188] Among them, based on equation (6), the correct application concentration of each biostimulant is determined, and multiple water resource quality data can be obtained. Select the water resource quality parameter that can meet the concentration requirements of all biostimulants to determine the water resource quality in the formula.

[0189] Among them, if it is found that there is no water resource quality that can meet the correct application concentration of all biostimulants, based on the influence of each type of biostimulant on the plant growth state, select the water resource quality input amount parameter that has the least impact on the overall formula for application.

[0190] After obtaining the improved formula, in fact, only the bio - stimulant mixture to be applied is determined. However, in some cases, in order to improve the growth level of the planted crops in a short time, other bio - stimulants need to be introduced. These bio - stimulants do not play a role in subsequent soil improvement and are even only applied for a very short time. Therefore, in the technical solution of this application, the following technical content is also included: S155. Based on the growth status of the planted crops in the soil improvement area, obtain the types of auxiliary bio - stimulants.

[0191] The purpose of this step is that for the crops in the soil improvement area, other types of bio - stimulants that may need to introduce bio - stimulants used in the improvement may be required, so as to determine other types of bio - stimulants to be input, in order to adjust the growth status of the planted crops in a short time.

[0192] Among them, determine the growth status of the planted crops.

[0193] Among them, based on the determination of the parameters of the growth status, determine other types of bio - stimulants that need to be configured, so as to obtain auxiliary bio - stimulants. For example, if it is found that there is a problem of excessive leaf shedding, in addition to reducing the dosage of abscisic acid, auxin also needs to be applied in the improvement stage to improve the leaf recovery speed.

[0194] Among them, for all types of auxiliary bio - stimulants, they are determined based on the rapid adjustment requirements of the growth status of the planted crops.

[0195] S156. Based on the growth status of the planted crops in the soil improvement area, obtain the demand for the active ingredients of the auxiliary bio - stimulants.

[0196] The purpose of this step is to determine the demand for the active ingredients on the basis of determining the types of auxiliary bio - stimulants, so as to determine the demand for the active ingredients.

[0197] Among them, during the adjustment of the growth status of the planted crops, according to the types of growth status to be adjusted, determine the demand for the active ingredients of the auxiliary bio - stimulants.

[0198] Among them, for the determination of the demand, it can be determined based on the actual demand and adjustment target of the planted crops, as well as the growth characteristics of the crops.

[0199] S157. Based on the demand for the active ingredients of the auxiliary bio - stimulants and the concentration of the active ingredients of the auxiliary bio - stimulants, obtain the concentration of the active ingredients in the auxiliary bio - stimulant mixture.

[0200] The purpose of this step is to lay a foundation for the subsequent determination of the application amount after the concentration of the active ingredient is determined.

[0201] Among them, in the determination of the concentration of the active ingredient, it can be determined based on the actual needs of the planted crops.

[0202] S158. When the concentration of the active ingredient in the auxiliary biostimulant mixture is lower than the preset active ingredient concentration, increase the application amount of the corresponding auxiliary biostimulant.

[0203] The purpose of this step is to directly determine the application amount of the auxiliary biostimulant based on the concentration of the active ingredient, and then determine the mixture formula of the auxiliary biostimulant.

[0204] Among them, regarding the application amount of the auxiliary biostimulant mixture and the application amount of each component therein, the determination method is the same as that of steps S151 - S154, and will not be elaborated here.

[0205] As described in step S160, the purpose of this step is to put the biostimulant mixture in the area where soil improvement is required, so as to adjust the growth state of the planted crops. Specifically: S161. Prepare the biostimulant mixture based on the improvement formula.

[0206] The purpose of this step is that for the obtained improvement formula, in which the application amounts of various biostimulant raw materials and the application amount of water resources have been determined, it can be directly determined based on this method.

[0207] Among them, for various biostimulant raw materials, only adjust the quality of the application amount according to the formula, and then obtain the mixture of this formula.

[0208] Among them, after determining the input amount of water resources, mix the water resources and various raw materials therein to obtain the biostimulant mixture.

[0209] Among them, in the facility agriculture technology, a high-level mixing adjustment of the mixture can be achieved, so as to realize the preparation of the mixture in the obtained data results.

[0210] S161. Based on the location of the soil improvement area, obtain the facilities for putting the biostimulant into the soil improvement area to obtain regional application equipment.

[0211] The purpose of this step is to determine the mixture application equipment in facility agriculture after obtaining the formula, so that in the specific treatment, directly based on the location of the soil improvement area, determine the area of the application equipment therein.

[0212] Among them, when it is found that the crops planted in the entire regional area in the soil improvement area grow poorly, it is inevitable that there is a correlation between the soil improvement area and the regional delivery device. Therefore, after determining the soil improvement area, the corresponding regional delivery device is directly determined based on the location of this area.

[0213] Among them, the switch structures of all the regional delivery devices are adjusted, and the biological stimulant mixture is delivered therein.

[0214] S163. Based on the regional delivery device, deliver the biological stimulant mixture to the soil improvement area.

[0215] The purpose of this step is that for the obtained biological stimulant mixture and the regional delivery device, the biological stimulant mixture can be directly delivered to the soil improvement area.

[0216] Among them, in the regional delivery device, the adjusted biological stimulant mixture is delivered therein.

[0217] Among them, in the regional delivery device, a corresponding mixture introduction switch is set in each regional delivery device. Through the switch adjustment, the biological stimulant mixture delivered by it can be adjusted.

[0218] In some embodiments, each regional delivery device is connected to all the biological stimulant raw materials and water resource input pipelines, and a flow valve is set on each pipeline. Then, in the specific soil improvement, by adjusting the opening and closing angle of the flow valve, the biological stimulant mixture is configured in the regional delivery device without prior configuration.

[0219] Among them, as Figure 3 shown, it is a schematic diagram of the control of the biological stimulant delivery area of a facility agriculture soil improvement method based on biological stimulants provided by an embodiment of the present application. Among them, the rectangular part is the soil improvement area, and two sets of regional delivery devices are set in each soil improvement area, and both have an input end and an output end. Especially for the drip irrigation device, these two sets of regional delivery devices can respectively introduce the biological stimulant mixtures with corresponding formulas. Among them, in the input end, the biological stimulant mixture that has been adjusted in formula is input therein to respectively deliver different biological stimulant mixtures to the soil improvement area, so as to achieve the effect of respectively improving the soil.

[0220] The beneficial effects of the present application include: 1. The precise delineation of the areas where soil improvement is needed is achieved. By determining the areas where the planted crops grow poorly, the concentrated areas of the poorly growing crops are analyzed. At the same time, by analyzing the growth status of the adjacent crops of the poorly growing crops, it is determined whether the problem occurs in a single plant or the entire cluster of crops. Based on the determination criteria, the areas where soil improvement is needed are determined to ensure that there is no inaccurate delineation of the areas where soil improvement is needed.

[0221] 2. The rationality of determining the formula of biostimulants is improved. In the analysis of the biological formula, based on the determined weight of the active ingredients required in the growth formula of the planted crops, the types of biostimulants are further determined. Then, based on the concentration of the active ingredients of the biostimulants, the mixture is analyzed to ensure that the concentration of each ingredient meets the growth requirements of the planted crops and ensure the rationality of the formula.

[0222] 3. The personalized improvement of the soil in the improved areas is achieved. After determining the division of the soil improvement areas, based on agricultural equipment, only the biostimulant mixture prepared based on the biostimulant formula is applied to the improved areas among them, so that only the biostimulants in the improved areas are adjusted and not in other areas. And for the improved areas in different regions, personalized biostimulant application is carried out for all regions, achieving the personalized improvement of the soil.
