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, regional isolation protection and regional drug delivery can be realized, which improves the utilization rate of drugs and resources to a certain extent. However, this also puts forward new requirements for drug types and drug delivery schemes. 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 delivery of biostimulants is too dependent 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 unified formula biostimulant mixture is often used for all areas within 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 deliver 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

The drawings are used to provide a further understanding of the present disclosure and constitute a part of the specification.

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying 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 in 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.

[0069] 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 precision of biostimulant formulation adjustment is insufficient, or even no formulation adjustment is 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 biostimulant is adjusted, the adjustment plan is for all planted crops. This leads to the situation that in the obtained adjustment effects, 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 the 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.

[0070] To solve the problems of the prior art, the present application discloses a facility agriculture soil improvement method based on biostimulants, such as Figure 1 shown in the flowchart of a facility agriculture soil improvement method based on biostimulants provided by an embodiment of the present application. Specifically:

[0071] 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.

[0072] S120. Obtain the growth status of the planted crops. If it does not meet the preset growth status standard, obtain the planted crops with poor growth.

[0073] S130. Obtain the concentrated distribution area of the planted crops with poor growth to obtain a cluster of poorly growing crops.

[0074] 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.

[0075] S150. Based on the growth status of the planted crops and the biostimulant demand table in the soil improvement area, obtain the biostimulant deviation amount.

[0076] S160. Based on the biostimulant deviation amount, obtain the biostimulant formulation for soil improvement to obtain an improved formulation.

[0077] S170. Based on the improved formula, apply biostimulants to the soil improvement area.

[0078] The purpose of all the above steps is to reasonably adjust the formula of the growth stimulant, accurately determine the area of the soil that needs to be transformed, and then make corresponding adjustments to the soil in the area that needs to be improved, so as to achieve personalized adjustment of each area and improve the soil improvement effect.

[0079] Next, the specific content of all the above steps will be described in detail. Specifically:

[0080] As described in step S110, the purpose of this step is to determine the planted crops, then analyze their requirements for biostimulants, and at the same time determine the performance of the planted crops when the application amount of biostimulants is unreasonable, laying a foundation for the subsequent analysis of the biostimulant requirements of the planted crops. Specifically:

[0081] S111. Obtain the varieties of planted crops within the covered area of protected agriculture.

[0082] The purpose of this step is to specifically determine the requirements for biostimulants based on the determined varieties of planted crops.

[0083] Among them, by determining the varieties of crops planted in this area, the requirements for biostimulants at different growth stages can be obtained.

[0084] In some embodiments, based on the soil and environmental performance of this area, determine the varieties of planted crops, and directly obtain the varieties of planted crops.

[0085] S112. Obtain the requirements for biostimulants of the planted crop varieties at different growth stages.

[0086] The purpose of this step is to, in the case of determining the requirements for growth stimulants at different stages, be able to determine and effectively solve the total amount of biostimulants applied in the current growth stage based on this indicator in the subsequent growth state analysis.

[0087] Among them, obtain the requirements for biostimulants of the crop varieties during different growth cycles.

[0088] Among them, it is also necessary to determine the types of requirements for biostimulants of the crop varieties during different growth cycles.

[0089] Among them, for each type of requirement for biostimulants, it needs to be determined separately.

[0090] Among them, for the requirement amount, it can be described based on indicators such as the concentration of biostimulants and the weight of active ingredients. This application does not make any limitations.

[0091] S113. Obtain the application amount of the growth stimulant at the time node based on the biological stimulant requirement and the time node of the growth stage.

[0092] The purpose of this step is to obtain the application amount of the biological stimulant based on the time node, so that in the subsequent adjustment and application of the biological stimulant formula, based on the recorded time node parameters, the deviation amount of the biological stimulant can be determined based on the time node.

[0093] Among them, for the determined planted crop, determine the occurrence time of each growth cycle after crop cultivation.

[0094] 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 after crop planting, so as to establish the corresponding relationship between the growth cycle and the corresponding growth time.

[0095] 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.

[0096] S114. When the application amount of the growth stimulant does not match the requirement of the cultivated crop, obtain the growth state of the planted crop to obtain a poor growth performance.

[0097] The purpose of this step is that in the growth of the planted crop, whether the biological stimulant applied to the planted crop is higher or lower than the crop requirement, 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.

[0098] Among them, based on the existing crop planting experience, determine the performance of the planted crop when it grows poorly, and determine the association between the performance and the biological stimulant.

[0099] Among them, for the poor growth performance, the specific performance settings include all poor growth performance situations such as leaf shedding of the plant, short plant height, and withered yellow plant leaves.

[0100] Among them, for all 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 indicate too much application amount of abscisic acid, etc.

[0101] In some embodiments, for each poor growth performance, the poor growth performance is quantitatively described, and for each quantitative description, a corresponding biological stimulant addition amount parameter is set, so as to establish a correspondence between the biological stimulant addition amount and the quantitative performance of the growth state.

[0102] S115. Establish the correspondence between the application amount of the biological stimulant, normal growth performance, poor growth performance and time nodes, and obtain the growth stimulant demand table.

[0103] The purpose of this step is that for the planted crops, by establishing the growth stimulant demand table, in the subsequent adjustment of the growth stimulant formula, the problems of the growth stimulant input in the growth of the current planted crops can be directly queried based on this demand table.

[0104] Among them, for the application amount of the growth stimulant, poor growth performance and growth time nodes of the planted crops, a one-to-one correspondence is established among them, so as to establish the growth information correspondence for all the factors among them.

[0105] 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 node can be used as the basic time point, and then: growth time - application amount of the growth stimulant - normal growth performance - poor growth performance when the application amount of the biological stimulant does not meet the index. The obtained result is the growth stimulant demand table.

[0106] Among them, there can be various corresponding forms of poor growth performance when the application amount of the biological stimulant does not meet the index. For each poor growth performance, it needs to be included in this growth stimulant demand table.

[0107] As described in step S120, the purpose of this step is to identify the growth state of the planted crops in the current entire area, and determine the planted crops with poor growth from them, so as to lay a foundation for the determination of the soil improvement area. Specifically:

[0108] S121. Obtain the image of the planted crops to get the crop image.

[0109] The purpose of this step is to directly obtain the growth image of the planted crops. Based on the image recognition method, 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, so as to reduce the analysis difficulty of the plant performance.

[0110] Among them, in the facility agriculture system, a plurality of cameras are set therein, and each camera uses a rotating scan method to obtain the plant images in the space it can scan.

[0111] Among them, during the shooting of crops, it is necessary to ensure that the set camera can cover all areas within the entire land range in terms of perspective, so as to determine the growth status of all plants.

[0112] Among them, during the process of obtaining images of planted crops, it is necessary to be able to separately select the obtained images. For the obtained images, frame images are also obtained from them, and these frame images are also used as crop images.

[0113] S122. Preprocess the crop image to obtain a preprocessed image.

[0114] The purpose of this step is that for the preprocessing of crop images, the shape performance of the currently photographed planted crops can be better recognized, so as to directly determine the growth status of the crops based on this image. [[ID=##]] [[ID=##]]

[0115] Among them, considering that biostimulants may cause changes in the color of crops, therefore, in specific processing, grayscale processing cannot be performed during preprocessing, but the color needs to be maintained.

[0116] Among them, the main image preprocessing methods include ways such as increasing contrast, screening out individual plants from the group based on the leaf edge line, and increasing brightness, which are not limited in this application.

[0117] Among them, for the preprocessing measures, it also includes the enlargement and reduction processing 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 demand table.

[0118] S123. Based on the preprocessed image, obtain the growth status performance of the planted crops.

[0119] The purpose of this step is that after obtaining the preprocessed image, directly analyze the growth status performance of the planted crops based on the adopted preprocessed image, so as to determine the growth problems of the planted crops.

[0120] Among them, after obtaining the preprocessed image, directly compare the growth status of the plants shown in this image with the normal growth performance in the biostimulant demand table to determine whether the currently planted crops are in a normal growth state.

[0121] In some embodiments, for the actual performance of the planted crops, directly compare it 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 currently planted crop plants show a poor growth state.

[0122] In some embodiments, when the pre - processed image is obtained, the plant performance in the image is directly described in terms of its status, including plant height, number of leaves, leaf color, etc. For example: Plant 112 - 32cm - 24 - light yellow (56%), light green (26%), dark green (18%), which means: the plant number is 112, the plant height is 32cm, the number of leaves is 24, and the color performance shows that the area proportion of light yellow is 56%, the area proportion of light green is 26%, and the area proportion of dark green is 18%.

[0123] Among them, for all the obtained performance data, they are compared with the relevant parameters in the already set normal growth state or poor growth state. In this case, data intervals are set for the performance data in the biostimulant requirement 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.

[0124] S124. Compare all the growth state performances with the normal growth state performance or the poor growth performance of the planted crops. If any of the growth state performances does not conform to the corresponding normal growth state, then the planted crop is a poorly growing planted crop.

[0125] The purpose of this step is to determine the poorly growing planted crops that can be currently monitored after obtaining the growth state performance of the planted crops.

[0126] Among them, the growth state performance of the obtained planted crops is represented together with the information in the growth stimulant requirement table.

[0127] Among them, compare the growth state performance with the already obtained normal growth state performance or the poor growth performance to determine the growth problems existing in the plant in the obtained image information.

[0128] Among them, if any of the growth state performances of the obtained plants does not conform to the normal growth state, or any of the growth state performances conforms to the poor growth performance, then the plant needs to be determined as a poorly growing planted crop.

[0129] As described in step S130, the purpose of this step is to, based on the obtained poorly growing planted crops, determine the clusters 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:

[0130] S131. Obtain the positions of the poorly growing planted crops to get the coordinates of the poorly growing crops.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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 kind of 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.

[0137] 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).

[0138] In some embodiments, the plants at 8 coordinates within the surrounding square range centered on the coordinates of the poorly growing crops can also be determined as adjacent plants.

[0139] Among them, the plants directly adjacent to the poorly growing planted crops are determined as the first adjacent plants.

[0140] 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 of steps S121 to S123, and will not be elaborated here.

[0141] 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.

[0142] 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.

[0143] Among them, the method for comparing the growth states is the same as that in step S124 and will not be elaborated here.

[0144] Among them, the preset growth state standard in this step is the normal growth state performance or the poorly growing performance.

[0145] S134. Obtain the growth state of the adjacent plants of the first adjacent plant with poor growth to obtain the growth state of the second adjacent plants.

[0146] The purpose of this step is to, after discovering the growth state of the first adjacent plant, use this plant as a reference to obtain the growth state of its adjacent plants.

[0147] Among them, the method of this step is the same as that of step S132 and will not be elaborated here.

[0148] S135. Compare the growth state of the second adjacent plants with the preset growth state standard to obtain the second adjacent plants with poor growth.

[0149] The purpose of this step is to analyze the growth state of the second adjacent plants to determine whether there are any planted crops with poor growth among the currently obtained second adjacent plants.

[0150] Among them, the method of this step is the same as that of S133 and will not be elaborated here.

[0151] S136. Obtain the growth states of the adjacent plants of all the planted crops with poor growth until the adjacent plants meet the preset growth state standard.

[0152] 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.

[0153] Among them, when it is found that the growth states of the adjacent plants of a certain planted crop with poor growth are all in the normal state, it is considered that this planted crop with poor growth is the outermost planted crop with poor growth in the entire area.

[0154] Among them, in order to avoid repetitive problems in analyzing the growth states of plants, after discovering a planted crop with poor growth, mark this plant, and in subsequent analyses of the growth states of adjacent plants, do not analyze the growth state of the already marked plants.

[0155] In some embodiments, other methods can also be used to avoid duplicate analysis work, and the present application does not limit this technical solution.

[0156] S137. Configure all the poorly growing planted crops into the same group of planted crops to obtain a cluster of poorly growing crops.

[0157] The purpose of this step is that for all the obtained poorly growing planted crops, their worlds need to be set into the same group of planted crops. Then, in subsequent operations, the areas that need soil improvement can be determined based on the distribution location of this cluster.

[0158] Among them, determine the areas of all the poorly growing planted crops, and set all the plants included in this area as a cluster of poorly growing crops.

[0159] Among them, for the poorly growing planted crops in this cluster of poorly growing crops, determine the outermost poorly growing plants and connect them. The planted crops within the coverage area of this connection are the cluster of poorly growing crops.

[0160] 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 location of the cluster of poorly growing crops is obtained. After that, the areas for soil improvement are determined based on this range.

[0161] Among them, as Figure 2 shown, it is a schematic diagram of the area for soil improvement of a method for improving facility agriculture soil 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 whole area can be determined, and the area where this cluster is located is the area for soil optimization.

[0162] As described in step S140, the purpose of this step is that on the one hand, the soil improvement location can be directly obtained based on the cluster of poorly growing crops, and on the other hand, it can be determined whether the current poorly growing crops show clustering due to accidental factors, so as to accurately determine the area for soil improvement. Specifically:

[0163] S141. Obtain the number of planted crops in the cluster of poorly growing crops to get the number of plants.

[0164] 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 process, after obtaining the number of plants, it can be used for the subsequent cluster scale judgment process.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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 process, 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, it is possible to determine the outermost planted crops in the soil improvement area.

[0169] Among them, obtain the outermost poorly growing planted crops in the poorly growing crop cluster and connect them.

[0170] 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.

[0171] Among them, for all the obtained outermost poorly growing planted crops, just connect their coordinates.

[0172] S143. Obtain the biostimulant absorption range of the outermost poorly growing planted crops to obtain the outer edge of the absorption range.

[0173] 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.

[0174] Among them, the determination of the edge of the absorption range can be based on the root coverage range of the planted crops.

[0175] In some embodiments, the agricultural facilities adjacent to the outer edge of the poorly growing planted crops are taken as the bio-stimulant absorption range, and the obtained result is the outer edge of the absorption range.

[0176] In some embodiments, it can also be determined based on the coverage range of the plant, and the projection of the coverage range of the plant on the ground is the outer edge of the absorption range.

[0177] S144. Connect the outer edges of all the absorption ranges to obtain the soil improvement area.

[0178] The purpose of this step is that in the analysis of the soil improvement area, since the planted crops will absorb the bio-stimulants in the soil, connecting all the outer edges of the absorption ranges, the corresponding area is the soil improvement area.

[0179] Among them, for the connected lines of the obtained absorption outer edges, directly connect the outer intersection points based on the intersection or tangent points of the outer edges of the absorption ranges to obtain the soil improvement area.

[0180] In some embodiments, for the obtained outer edges of the absorption ranges, since there are multiple middle crop plants with poor growth at the outermost edges, 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.

[0181] In some embodiments, if the bio-stimulant absorption range is determined based on the coverage range of the plant, then in the drawing of the connected lines of the outer edges of the absorption range, connect the lines based on the projected area on the ground to obtain the soil improvement area.

[0182] In some embodiments, connect the lines based on the positions or coordinates of the planted crops with poor growth at the outermost edges to obtain the plant coverage range, and then integrate the area of the bio-stimulant absorption range into this plant coverage range to obtain the soil improvement area.

[0183] It should be noted that in the facility agriculture system, in 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 bio-stimulants. Obviously, for this situation, only applying a bio-stimulant 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 bio-stimulants in the soil improvement areas, so as to further adjust the soil improvement areas. Specifically:

[0184] S145. Obtain the growth status of all the poorly growing planted crops within the soil improvement area to obtain the status of each plant within the area.

[0185] The purpose of this step is to lay a foundation for determining the demand deviation of the biological stimulant required for all the plants by determining the growth status of all the poorly growing planted crops within the soil improvement area.

[0186] Among them, obtain the images of all the plants within the entire soil improvement area and establish each individual image.

[0187] Among them, for each individual image of a plant, determine the status of the plant. The specific determination method and steps S121 - S123 are the same and will not be elaborated here.

[0188] S146. Compare the status of each plant within the area with the preset growth status standard to obtain the defects of the poorly growing cultivated crops.

[0189] 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 the different status manifestations among them, and thus determine the association between this status manifestation and the incorrect application amount of the biological stimulant.

[0190] Among them, for the defects of the poorly growing cultivated crops, for the preset growth status standard, it can be directly set based on the established biological stimulant demand table.

[0191] Among them, for the confirmation of the defects of all the poorly growing cultivated crops, the method is the same as that in step S124 and will not be elaborated here.

[0192] 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.

[0193] 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.

[0194] Among them, determine the status of all the plants therein and identify the specific manifestations of this plant status.

[0195] Among them, mark the specific manifestations of the plant status and determine the locations of the plants with the same poorly growing manifestations.

[0196] Among them, determine whether the plants marked with the poorly growing manifestations are adjacent. If they are adjacent, set these two plants into the same aggregation space.

[0197] 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.

[0198] S148. Based on the aggregation space, divide the soil improvement area to obtain a divided area of the soil improvement area.

[0199] 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.

[0200] Among them, obtain the outermost planted crops of the planted crops with the same poor growth state for area division.

[0201] 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.

[0202] In some embodiments, the method for determining the divided area is similar to step S137, and it is necessary to delimit the absorption range of the biostimulant therein and then perform area division.

[0203] In some embodiments, considering that the absorption ranges of two kinds of planted crops with different 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 the 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.

[0204] 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.

[0205] 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:

[0206] S151. Obtain the growth state of the planted crops in the soil improvement area to obtain the plant performance.

[0207] The purpose of this step is that for the soil improvement area, the growth states of the planted crops are all in a poor growth state, and their growth state performances are the same. This means that all the crops in this area have the same problem of the application amount of biostimulants. Therefore, in order to determine the problem of biostimulant application, it is necessary to further analyze the plant performances.

[0208] Among them, for the plant performances, 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.

[0209] Among them, for all the plant performances, they all need to be recorded, and all the parameters are used as the basis for the subsequent judgment process.

[0210] In some embodiments, the mean values of all the performance data are respectively calculated to obtain the normalization processing result.

[0211] S152. Compare the obtained plant performances with the poor growth performances in the biostimulant demand table to obtain the application amount of growth stimulants.

[0212] The purpose of this step is that for all the obtained plant performance parameters, they all need to be compared with the corresponding poor growth performances, and then the relationship between each poor growth performance and the application amount of biostimulants can be determined to determine the problems existing in the current biostimulant application.

[0213] Among them, in the biostimulant demand table, the poor growth performances corresponding to the unreasonable application amount of biostimulants have been set for comparison. For example: during the filling period of a certain crop, it is found that the leaves turn yellow. At this time, the biostimulant demand table states the degree of leaf yellowing when different concentrations of abscisic acid are applied, and then the deviation amount of the current abscisic acid application amount is directly determined based on this performance.

[0214] Among them, for all the performances of the planted crops caused by the deviation of the application amount of growth stimulants, all the performances generated need to be compared with the corresponding poor growth performances. 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.

[0215] In some embodiments, for each performance state of the plant, its mean value is calculated, and then the mean value is directly compared with the poor growth performance to determine the current application amount of biostimulants.

[0216] Among them, for the case where the mean value is not obtained, each plant is compared, and the amount of biostimulant applied to the planted crops in this area is determined, and then the mean value is obtained.

[0217] S153. Obtain the difference between the amount of growth stimulant applied and the requirements of the cultivated crops to obtain the growth stimulant deviation amount.

[0218] The purpose of this step is that based on the determination of the deviation amount, in the subsequent formulation adjustment, according to the size of the deviation amount, the increase or decrease amounts of all substances in the corresponding growth stimulant formulation can be adjusted accordingly, and the biostimulant application ratio in the formulation can be set.

[0219] Among them, for the actually obtained biostimulant application amount, the deviation amount can be obtained directly by calculating the difference between the biostimulant content normally applied in the biostimulant requirement table.

[0220] 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 problem and the deviation amount has been determined, it is necessary to improve the biostimulant formulation for this deviation amount, and then the growth state of the planted crops can be adjusted based on this improved formulation. Specifically:

[0221] S161. Based on the growth state of the planted crops, obtain the types of various biostimulants applied to the soil improvement area.

[0222] The purpose of this step is that for the growth state of the planted crops that has been obtained, the types of unreasonable biostimulant applications in the current crop growth can already be known, and then the biostimulant can be adjusted accordingly, that is, the adjustment types of the biostimulant are obtained.

[0223] Among them, according to the growth state of the planted crops and the comparison results between this growth state and the biostimulant requirement table, the types of unreasonable biostimulant application amounts are determined.

[0224] Among them, for the obtained biostimulant types, according to the comparison results, the biostimulant types that need to be adjusted subsequently are marked.

[0225] S162. Based on the biostimulant deviation amount, obtain the weights of the active ingredients of various biostimulants applied to the soil improvement area.

[0226] The purpose of this step is that in the determination of the deviation amount of biostimulants, the possible deviation amounts include concentration, proportion of active ingredient, weight of active ingredient, etc. In any case, a standard needs to be set. Among them, for the determination of the weight of the active ingredient, it is obviously the best way to determine the standard.

[0227] Among them, in the determination of the concentration deviation amount, based on the concentration difference, directly determine the weight value of the active ingredient currently put in.

[0228] Among them, if it is determined based on the weight of the active ingredient, just directly calculate the difference.

[0229] Among them, for other deviation amounts, the weight of the active ingredient can also be determined according to the corresponding processing methods.

[0230] S163. Obtain the application amount of the biostimulant based on the weights of the active ingredients of various biostimulants and the concentrations of the active ingredients of various biostimulants.

[0231] The purpose of this step is that for the biostimulants that need to be adjusted, it is necessary to process the application amount of the biostimulants that need to be adjusted according to their types and the weights of the active ingredients that have been obtained. It should be noted that this application is based on objects such as solutions and aerosols of biostimulants, and in the application of biostimulants, it may be necessary to apply them based on mixtures. In this case, the application amount of the biostimulant among them refers to the determination of the application amount to objects such as solutions or aerosols.

[0232] Among them, for the processing of the application amount, it can be directly determined based on the concentration of the raw material.

[0233] Among them, the concentration of the raw material should be significantly higher than the concentration of the active ingredient in the biostimulant that needs to be actually applied.

[0234] 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 biostimulant concentration among the planted crops.

[0235] Among them, in the case of a biostimulant mixture, it is necessary to determine the concentrations of the raw materials of all the biostimulants that need to be applied, and then determine the concentrations of each biostimulant. The equation is as follows:

[0236] ;

[0237] Among them, represents the concentration of the i th biostimulant, represents the application amount of the i th biostimulant,i Indicates the category index of biostimulants, j Indicates the total amount of category indices of biostimulants, Indicates the i concentration deviation of the

[0238] th biostimulant. For this step, its function is to compare the concentrations of all the obtained biostimulants with the concentration of the correctly applied biostimulant. That is to say, Equation (1) is an equation for verification. If it is found that the concentration of one of the biostimulants is different from the correctly applied concentration, the weight parameter therein needs to be adjusted accordingly.

[0239] Among them, for all biostimulants, it is necessary to calculate their concentrations to obtain the application amount of the finally applied biostimulant.

[0240] ;

[0241] Among them, indicates the application amount of the raw material of the i th biostimulant, indicates the concentration of the raw material of the i th biostimulant.

[0242] Among them, for the concentration of the i th biostimulant obtained, the calculation result is obtained, and the effective ingredient concentration of each biostimulant and the required application amount are respectively analyzed to obtain various concentration results therein.

[0243] Among them, when it is found that the effective ingredient concentration therein does not meet the requirements, the formula needs to be further adjusted.

[0244] S154. Obtain the application amounts of all the biostimulants and obtain the effective ingredient concentrations of all the biostimulants in the biostimulant mixture to obtain an improved formula.

[0245] The purpose of this step is that for the effective ingredient concentration of the biostimulant, it is possible that the concentration of a certain biostimulant does not meet the application amount requirement. In order to ensure to the greatest extent that the concentrations of all biostimulants meet the requirements of the effective ingredient concentration, the formula needs to be further adjusted.

[0246] Among them, corresponding treatments are carried out for determining the types of various biostimulants and the weights of the effective ingredients. Among them, it is necessary to determine the proportion of the weights of all the effective ingredients, so as to obtain the application proportion of various biostimulants in the formula. The specific calculation equation is:

[0247] ;

[0248] Among them, represents the weight of the active ingredient in the application amount of the p th biostimulant, p represents the index of the weight of the active ingredient in the application amount of the biostimulant, q represents the total index of the weight of the active ingredient in the application amount of the biostimulant, represents the proportion of the active ingredient in the application amount of the p th biostimulant.

[0249] Among them, it is necessary to obtain the proportion of the dosage of each biostimulant, and its calculation equation is:

[0250] ;

[0251] Among them, represents the dosage weight of the p th biostimulant.

[0252] Among them, after considering the proportion of the active ingredient, the raw material dosage of various biostimulants is obtained, and its equation is:

[0253] ;

[0254] 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 dosage weight of the biostimulant is determined based on the weight.

[0255] Among them, after determining each raw material dosage parameter, the configuration is carried out based on the dosage.

[0256] Among them, when it is found that after the dosage configuration, the concentration of the active ingredient of the biostimulant in it does not meet the correct dosage standard, water resources are added to the mixture. Among them, equation (1) is modified to:

[0257] ;

[0258] Among them, represents the quality of the added water resources.

[0259] Among them, based on equation (6), the correct dosage concentration of each biostimulant is determined, and multiple water resource quality data can be obtained. Select the water resource quality parameters that can meet the concentration requirements of all biostimulants to determine the water resource quality in the formula.

[0260] Among them, when 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 various biostimulants on the growth state of plants, the input amount parameter of the water resource quality with the least overall impact on the formula is selected for application.

[0261] After obtaining the improved formula, in fact, only the mixture of biostimulants 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 biostimulants need to be introduced. These biostimulants 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:

[0262] S155. Based on the growth state of the planted crops in the soil improvement area, obtain the types of auxiliary biostimulants.

[0263] The purpose of this step is to determine the types of other biostimulants that may need to be introduced for the crops in the soil improvement area, so as to determine the types of other biostimulants that need to be input, in order to adjust the growth state of the planted crops in a short time.

[0264] Among them, the growth state of the planted crops is determined.

[0265] Among them, based on the determination of the parameters of the growth state, the types of other biostimulants that need to be configured are determined, so as to obtain the auxiliary biostimulants. For example, if it is found that there is a problem of excessive leaf shedding, in addition to reducing the application amount of abscisic acid, auxin also needs to be applied during the improvement stage to increase the leaf recovery speed.

[0266] Among them, for all types of auxiliary biostimulants, they are determined based on the rapid adjustment requirements of the growth state of the planted crops.

[0267] S156. Based on the growth state of the planted crops in the soil improvement area, obtain the demand for the active ingredients of the auxiliary biostimulants.

[0268] The purpose of this step is to determine the demand for the active ingredients on the basis of determining the types of auxiliary biostimulants, so as to determine the demand for the active ingredients.

[0269] Among them, according to the types of growth states that need to be adjusted during the adjustment of the growth state of the planted crops, the demand for the active ingredients of the auxiliary biostimulants is determined.

[0270] 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.

[0271] S157. Obtain the active ingredient concentration in the auxiliary biostimulant mixture based on the required amount of the active ingredient of the auxiliary biostimulant and the active ingredient concentration of the auxiliary biostimulant.

[0272] 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.

[0273] Among them, in the determination of the active ingredient concentration, it can be determined based on the actual needs of the planted crops.

[0274] S158. When the active ingredient concentration in the auxiliary biostimulant mixture is lower than the preset active ingredient concentration, increase the application amount of the corresponding auxiliary biostimulant.

[0275] The purpose of this step is to directly determine the application amount of the auxiliary biostimulant based on the active ingredient concentration, and then determine the mixture formula of the auxiliary biostimulant.

[0276] 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.

[0277] 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:

[0278] Sect. 161. Prepare the biostimulant mixture based on the improvement formula.

[0279] The purpose of this step is that for the obtained improvement formula, the application amounts of various biostimulant raw materials and the application amount of water resources have been determined, and it can be directly determined based on this method.

[0280] 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.

[0281] Among them, after determining the input amount of water resources, mix the water resources and various raw materials to obtain the biostimulant mixture.

[0282] Among them, in facility agriculture technology, high-level mixing adjustment of the mixture can be achieved, so as to achieve the preparation of the mixture in the obtained data results.

[0283] 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.

[0284] The purpose of this step is to determine the mixture dispensing equipment in facility agriculture after obtaining the formulated mixture, so that in specific processing, based directly on the location of the soil improvement area, the dispensing equipment therein can be determined for the area.

[0285] Among them, when it is found that the growth of the planted crops in the entire regional area in the soil improvement area is poor, it is found that there must be a correlation between the soil improvement area and the regional dispensing equipment. Therefore, after determining the soil improvement area, based directly on the location of this area, the corresponding regional dispensing equipment is determined.

[0286] Among them, the switch structures of all the regional dispensing equipment are adjusted, and the bio-stimulating mixture is dispensed therein.

[0287] S163. Based on the regional dispensing equipment, dispense the bio-stimulating mixture to the soil improvement area.

[0288] The purpose of this step is that for the obtained bio-stimulating mixture and the regional dispensing equipment, the bio-stimulating mixture can be directly dispensed to the soil improvement area.

[0289] Among them, in the regional dispensing equipment, the adjusted bio-stimulating mixture is dispensed therein.

[0290] Among them, in the regional dispensing equipment, a corresponding mixture introduction switch is set in each regional dispensing equipment, and through the switch adjustment, the bio-stimulating mixture dispensed by it can be adjusted.

[0291] In some embodiments, each regional dispensing equipment is connected to all the bio-stimulating raw material and water resource input pipelines, and a flow valve is set on each pipeline. Then, in specific soil improvement, by adjusting the opening and closing angle of the flow valve, the bio-stimulating mixture is configured in the regional dispensing equipment without prior configuration.

[0292] Among them, as Figure 3 shown, it is a schematic diagram of the control of the bio-stimulating dispensing area of a bio-stimulating-based facility agriculture soil improvement method provided by an embodiment of the present application. Among them, the rectangular part is the soil improvement area, and two sets of regional dispensing equipment are set in each soil improvement area, and both have an input end and an output end. Especially for drip irrigation equipment, these two sets of regional dispensing equipment can respectively introduce the bio-stimulating mixture of the corresponding formula. Among them, in the input end, the bio-stimulating mixture that has been adjusted by the formula is input therein to perform the separate dispensing of different bio-stimulating mixtures to the soil improvement area, so as to achieve the separate improvement effect on the soil.

[0293] The beneficial effects of this application include:

[0294] 1. It realizes the precise delineation of the areas that need soil improvement. 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 that need soil improvement are determined to ensure that there will be no inaccurate delineation of the areas that need soil improvement.

[0295] 2. It improves the rationality of determining the formula of biostimulants. 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.

[0296] 3. It realizes the personalized improvement of the soil in the improved areas. After determining the division of the soil improvement areas, based on agricultural equipment, only the biostimulant mixture formulated based on the biostimulant formula is applied to the improved areas among them, so that only the improved areas are adjusted for biostimulants, and other areas are not adjusted. And for the improved areas in different regions, personalized biostimulant application is carried out for all regions, realizing the personalized improvement of the soil.
