Description

Technical Field

[0001] This application belongs to the field of facility agriculture technology, specifically, it relates to a method for adjusting the dosage of soil acidification conditioner. Background Technology

[0002] In recent years, the excessive use of chemical fertilizers and the lack of fallow land in my country's crop cultivation have led to soil acidification. Soil acidification, in turn, reduces crop yields, prompting farmers to further increase fertilizer application, creating a vicious cycle. To restore soil fertility, various regions have begun widespread soil acidification treatment programs. Current methods include the application of conditioners and crop rotation with soil acidification-regulating capabilities. The latter requires a longer time frame and often fails to meet the urgent needs of soil acidification treatment. The former, currently relying on continuous, high-volume application, is prone to exceeding the soil's carrying capacity, leading to soil salinization, or insufficient application resulting in low soil acidification regulation capacity. Therefore, both methods are inefficient and ineffective in meeting the requirements for soil acidification treatment.

[0003] Therefore, how to improve the reasonable adjustment of the dosage of soil acidification conditioners to ensure the efficiency and effectiveness of conditioning acidified soil is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0041] Based on the baseline soil acidification conditioner dosage and the duration of the next conditioning cycle, the soil acidification conditioner dosage rate for the next conditioning cycle is obtained to arrive at the baseline dosage rate.

[0042] According to the aforementioned baseline application rate, continue to apply soil acidification conditioner to the transition layer of the next conditioning cycle;

[0043] After the start of the next conditioning cycle, the concentration of acidic substances in the transition layer of the next conditioning cycle is obtained in real time.

[0044] Optionally, the real-time adjustment of the soil conditioner dosage in the severely acidified layer of the next conditioning cycle, so that the acid concentration in the severely acidified layer of the next conditioning cycle is the same as the acid concentration in the transition layer of the next conditioning cycle, includes:

[0048] Optional, also includes:

[0049] After each soil acidification conditioning cycle is completed and the soil is tilled, the concentration of acidic substances in the soil after tilling is obtained.

[0050] Based on the comparison between the concentration of acidic substances in the soil after tilling and the preset concentration of acidic substances in the soil after tilling, the soil acidification conditioner is supplemented and applied based on the comparison results.

[0051] The beneficial effects of this application include:

[0052] 1. Improved soil conditioning efficiency. The technical solution of this application obtains a strongly acidified layer and a filter layer in acidic soil. Different methods of applying soil acidification conditioners are used for the two layers, which improves the conditioning efficiency of the strongly acidified layer. After that, these two layers are tilled. Based on the tilling operation, the total content of acidic substances in the soil above the base layer can be reduced. Under the most ideal conditions, the acidic soil can be thoroughly conditioned within one cycle.

[0053] 2. Improved soil conditioning effect. In the technical solution of this application, the soil to be conditioned is divided into a severely acidified layer and a transitional layer. Different conditioning schemes are adopted for the two layers. The former is conditioned with soil acidification conditioner applied based on actual measurement results, which greatly improves the conditioning effect. For the transitional layer, since the acid content is relatively stable and low, a stable conditioner application scheme can be used for treatment. This ensures that the acid content in the soil of the severely acidified layer decreases at a higher rate and can cope with various possible fluctuations. Ultimately, it ensures that the acid content in the severely acidified layer decreases continuously, stably and effectively. Overall, the soil conditioning effect is improved.

[0054] 3. Improved stability of soil conditioning effects. During soil conditioning, various changes may occur in the natural environment. For example, rainfall may introduce more acidic substances into the soil. Therefore, it is necessary to improve the stability of soil conditioning levels to maintain the conditioning quality of acidic soils. In this application's technical solution, the acid content of the strongly acidified layer is monitored in real time. Based on the real-time monitoring results, the application rate of the soil acidification conditioner can be adjusted in real time to ensure the stability of the soil conditioning effect.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Furthermore, in the embodiments of this application, "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0060] Regarding the application of soil acidification conditioners, both excessive and insufficient application will result in inadequate soil conditioning effects. Therefore, it is crucial to significantly improve the quality of soil acidification conditioner application. Current adjustment methods primarily focus on controlling the spraying volume of the conditioner; that is, ensuring all the conditioner is applied within a given conditioning cycle. While the dosage is calculated, various environmental factors can significantly reduce the effectiveness of soil conditioners in adjusting soil acidification. Some methods limit the application volume per unit time, but these still lack effective adjustments based on fluctuations in acidic levels. In other words, current methods for applying soil acidification conditioners face the challenge of achieving continuous, effective, and efficient dosage adjustments.

[0061] To address the problems existing in the methods for adjusting the dosage of soil acidification conditioners, this application discloses a method for adjusting the dosage of soil acidification conditioners, specifically:

[0062] S110. Obtain the concentration data of acidic substances in the soil and obtain the strongly acidified layer and transition layer.

[0063] S120. Based on the initial acidic substance concentrations of the strongly acidified layer and the transition layer, the initial dosage of the soil acidification conditioner was obtained and applied.

[0064] S130. Real-time acquisition of the measured concentration of acidic substances in the severely acidified layer, and adjustment of the dosage of soil acidification conditioner applied to the severely acidified layer.

[0065] S140. After one soil conditioning cycle, the conditioned strongly acidified layer and transition layer are tilled to obtain the soil for the next conditioning cycle.

[0066] S150. Based on the concentration of acidic substances in the soil in the next conditioning cycle, obtain the baseline soil acidification conditioner dosage for the next conditioning cycle.

[0067] S160. Real-time acquisition of soil acid concentration in the vertical direction for the next conditioning cycle, and acquisition of the strongly acidified layer and transition layer for the next conditioning cycle.

[0068] S170. Based on the baseline soil acidification conditioner dosage, apply soil conditioner to the transition layer of the next conditioning cycle and obtain the acidic substance concentration of the transition layer in the next conditioning cycle.

[0069] S180. Adjust the amount of soil conditioner applied to the severely acidified layer in the next conditioning cycle in real time, so that the concentration of acidic substances in the severely acidified layer in the next conditioning cycle is the same as the concentration of acidic substances in the transition layer in the next conditioning cycle.

[0070] The beneficial effects of the above steps are that they achieve highly efficient and effective conditioning of acidified soil. Furthermore, by reasonably adjusting the dosage of soil conditioner during the conditioning process, the stability of the soil conditioning effect is always maintained, thereby improving the quality of soil conditioning.

[0071] The following will provide a detailed explanation of all the steps above:

[0072] As described in step S110, the purpose of this step is to identify the strongly acidified layer and the transition layer in the soil during the initial or initial cycle of soil conditioning, thereby laying the foundation for determining the dosage and application rate required for the subsequent two layers. Specifically:

[0073] S111. Data on the concentration of acidic substances in the soil is obtained based on an acidic substance monitoring device group, wherein the acidic substance detection group consists of multiple acidic substance detection sensors that are evenly distributed and distributed in the longitudinal direction in the soil.

[0074] The purpose of this step is to determine that the content and concentration of acidic substances in the strongly acidified layer and the transition layer of acidic soil are different, and even have a very obvious stratification effect to a certain extent. In order to determine the specific stratification location, it is necessary to set up detection hardware equipment to determine the concentration data of acidic substances.

[0075] Among them, the acidic substance monitoring device group needs to be installed in the soil in a vertical direction.

[0076] Among them, such as Figure 2 The diagram shows the arrangement of a monitoring device group for a method of adjusting the dosage of soil acidification conditioner provided in this application embodiment. Each monitoring group is equipped with multiple acidic substance detection sensors to obtain the content or concentration of acidic substances in the vertical direction of the soil.

[0077] For the acidic substance monitoring device group, it needs to be evenly deployed throughout the entire area that needs to be conditioned, so as to ensure that the content or concentration of acidic substances in each area of ​​the entire plot can be confirmed.

[0078] In determining the spacing of the acidic substance monitoring device groups, it can be set according to the radiation range of the soil acidification conditioner inserted in the soil along the total longitudinal direction of the soil, that is: ensuring that the spacing between two adjacent monitoring device groups is not greater than the radiation range of the conditioner dispensed by a single soil acidification conditioner dispenser.

[0079] S112. Set up acidic substance monitoring device groups evenly in the soil acidification area and obtain the acidic substance concentration at different depths for each acidic substance monitoring device group.

[0080] The purpose of this step is to address the issue that, during the application of soil acidification conditioners, various environmental factors in the underground soil environment can affect the accumulation of acidic substances, such as groundwater runoff and soil transport rate. This can lead to different thicknesses in the transition layer of the strongly acidified layer. In response to this situation, this application has established a flexible application mechanism. To achieve flexible application, the data obtained by each acidic substance monitoring device group is directly determined to identify the concentration of acidic substances at different depths.

[0081] Among them, based on the set acidic substance monitoring device group, all sensors in each monitoring group acquire the concentration of acidic substances at their depth and location.

[0082] In this process, the validity of the parameters is checked for the concentration of acidic substances measured by each sensor. For example, if the concentration of acidic substances measured by the middle sensor is significantly higher or lower than that measured by the other two sensors out of no fewer than three consecutive sensors, then that data is discarded.

[0083] S113. Obtain the acid concentration difference between adjacent acid detection sensors within each acid substance monitoring device group, and obtain adjacent acid detection sensors whose difference is not lower than a preset difference.

[0084] The purpose of this step is to determine the screening method, given the significant difference in acid concentration between the strongly acidified layer and the transition layer, in order to distinguish between these two layers.

[0085] Among them, the acid substance monitoring device group includes all sensors that are adjacent to each other.

[0086] Among them, the concentrations of the two acidic substances obtained from all adjacent sensors are acquired;

[0087] If the difference in the measured concentrations is not lower than the preset difference, then the two sensors are considered to be sensors at different levels.

[0088] In some embodiments, when two sensors at different levels are acquired, it is also necessary to determine the difference in acidic substance concentration measured by adjacent sensors in the strongly acidified layer and the transition layer, respectively. When the difference is found to be no more than a preset difference, it is considered that the adjacent sensors with a difference not lower than the preset difference belong to different levels. If there are still adjacent sensors with a difference not lower than the preset difference, the data set of the sensors above or below the adjacent sensor is determined, thereby eliminating possible erroneous sensor groups.

[0089] S114. Obtain the midpoint of the adjacent acidic substance detection sensors whose difference is not lower than the preset difference. The area from the midpoint upwards to the soil surface is the strongly acidified layer, and the area from the midpoint downwards to the deep soil layer is the transition layer.

[0090] The purpose of this step is to identify the heavily acidified and transitional layers of the soil.

[0091] Among them, when it is determined that the difference in the measured concentration is not lower than the preset difference between adjacent sensors, the focus of these two sensors is the boundary between the strongly acidified layer and the transition layer.

[0092] In typical acidic soils, the strongly acidified layer is located in the surface area, while the transition layer is located in the middle layer of the soil. Therefore, the area above the dividing point is the strongly acidified layer, and the area below it is the transition layer.

[0093] The preset difference can be set based on the experience of technicians, or determined based on the fluctuation of multiple differences calculated between adjacent sensors, or determined by other methods. This application does not limit the method.

[0094] The beneficial effect of step S110 is that, through the set acid substance monitoring device group, the concentration data of acid substances in the longitudinal direction of the soil can be distinguished, thereby obtaining the concentration data of acid substances at different depths in the area where each acid substance monitoring device group is located, and then determining the strongly acidified layer and the transition layer, thereby fully realizing the decomposition of the strongly acidified layer and the transition layer at the location of each acid substance monitoring device group, so as to achieve flexible regulation of each small area in the plot.

[0095] As described in step S120, the purpose of this step is to first determine the basic dosage data of the soil acidification conditioner during the conditioning of acidified soil. Only then can subsequent adjustments be made based on this data; that is, to lay the foundation for real-time adjustment of the dosage of the soil acidification conditioner. Specifically:

[0096] S121. Before applying the soil acidification conditioner, the average concentration of acidic substances in the strongly acidified layer and the transition layer is obtained based on the acidic substance monitoring device group, so as to obtain the initial concentration of acidic substances in the strongly acidified layer and the transition layer.

[0097] The purpose of this step is to obtain the concentration parameters of acidic substances in the strongly acidified layer and the transition layer. Then, based on this data, the dosage of soil acidification conditioner for the two benchmark layers can be directly determined.

[0098] Specifically, for the strongly acidified layer and the transition layer, the concentration data of acidic substances obtained by each sensor in different layers are acquired, and the average value is calculated to obtain the concentration data of acidic substances in that layer.

[0099] In some embodiments, if sensor data in the strongly acidified layer and transition layer is found to be obviously erroneous, the data is discarded and replaced with data measured by the surrounding sensors.

[0100] S122. Based on the initial acidic substance concentration of the strongly acidified layer and the transition layer and the target soil acidic substance concentration after the current soil conditioning cycle is completed, obtain the dosage of soil acidification conditioner for the strongly acidified layer and the transition layer.

[0101] The purpose of this step is to determine the amount of soil acidification conditioner to be applied to the severely acidified layer and the transition layer after obtaining the initial concentration of acidic substances. This will determine the total amount of soil acidification conditioner to be applied to the severely acidified layer and the transition layer within a certain period.

[0102] Among them, the soil volume of the strongly acidified layer or transition layer within the radiation range of the acid substance monitoring device group is obtained.

[0103] After determining the soil acidification conditioner concentrations in the strongly acidified layer and the transition layer, the current soil acid concentrations in the strongly acidified layer and the transition layer are calculated directly based on the soil volume of the strongly acidified layer and the transition layer.

[0104] Specifically, the target concentration of soil acidic substances after the conditioning work is completed within the current conditioning cycle is determined, and based on this target parameter, the total consumption of soil acidic substances within the obtained strata during the current conditioning cycle is obtained. The equation is as follows:

[0105] ,

[0106] Among them, M f V represents the total consumption of soil acidic substances in the strongly acidified layer or transition layer during the current conditioning cycle; C0 represents the soil volume within the radiation range of the selective substance monitoring device group in the strongly acidified layer or transition layer; C1 represents the target soil acidic substance concentration in the strongly acidified layer and transition layer after the completion of the current soil conditioning cycle.

[0107] After determining the total consumption of soil acidic substances in different layers, it is necessary to determine the dosage of soil acidification conditioner. The specific dosage equation is as follows:

[0108] ,

[0109] Among them, M t This indicates the baseline dosage of soil acidification conditioner within the current soil conditioning cycle; δ represents the amount of soil acidification conditioner required to eliminate 1 unit of soil acidic substances, i.e., the dosage ratio of soil acidification conditioner to soil acidic substances.

[0110] S123. Based on the dosage of soil acidification conditioner in the strongly acidified layer and the transition layer and the current soil conditioning cycle length, obtain the application rate of soil acidification conditioner in the strongly acidified layer and the transition layer.

[0111] The purpose of this step is that, after determining the dosage of soil acidification conditioner for the severely acidified layer and the transition layer, it is clear that the conditioner cannot be directly applied in its entirety. Instead, it needs to be applied continuously to maintain the effect. In addition, in order to ensure the conditioning effect, it is also necessary to eliminate the fluctuations in the amount of soil acidity. Therefore, it is also necessary to obtain parameters that can eliminate fluctuations based on the dosage of soil acidification conditioner for the severely acidified layer and the transition layer.

[0112] Among them, the duration of the current soil conditioning cycle is obtained, which is determined by the conditioning work plan.

[0113] The dosage of soil acidification conditioner in the severely acidified layer and transition layer is obtained to determine the application rate. The specific equation is as follows:

[0114] ,

[0115] Among them, v t This indicates the application rate of soil acidification conditioner in the strongly acidified layer and the transition layer; t indicates the duration of the current soil conditioning cycle.

[0116] It should be noted that this step obviously does not take into account various possible fluctuation factors. Therefore, this delivery speed value can be considered as a benchmark speed value.

[0117] S124. Based on the soil acidification conditioner dispenser, the soil acidification conditioner is continuously dispensed according to the dispensing rate of the obtained strongly acidified layer and transition layer.

[0118] The purpose of this step is to ensure that, after obtaining the application rate, the soil acidification conditioner is continuously applied, and the application parameters are determined based on the obtained application rate.

[0119] Among them, the soil acidification conditioner dispenser needs to be set up synchronously with the acidic substance monitoring device group, that is, it is configured as a group with the acidic substance monitoring device group.

[0120] The soil acidification conditioner dispenser is inserted vertically into the soil and includes multiple independent openings to independently adjust the dispensing rate of the soil acidification conditioner in the strongly acidified layer and the transition layer based on these independent openings. Figure 3 The diagram shown is a schematic of the arrangement of the soil acidification conditioner dispenser in a method for adjusting the dosage of soil acidification conditioner provided in this application embodiment. The so-called acidic substance monitoring device group and soil acidification conditioner dispenser integration group refers to a combination device that combines the acidic substance monitoring device group and the soil acidification conditioner dispenser.

[0121] In the case of the set up dispenser and monitoring device group, if the number of openings and sensors in the dispenser is the same, it is necessary to ensure that the opening is located below the sensor and the distance from the next sensor is much greater than that from the previous sensor, so as to avoid the soil acidification conditioner dispensed by the dispenser being detected by the sensor, which would cause serious interference to the values ​​measured by the sensor.

[0122] The beneficial effect of step S120 is that it enables the determination of the application rate of soil acidification conditioner, allowing for continuous application to the soil according to this value. Furthermore, different application rates of soil acidification conditioner can be used for strongly acidified layers and transitional layers, thus enabling different conditioning measures to be adopted for different soil layers.

[0123] As described in step S130, the purpose of this step is to reduce resource consumption in the control process, considering that almost all farmland has a higher degree of surface acidification and a relatively stable transition layer. Therefore, there is no need to adjust the transition layer; only stabilization adjustment is required. This also effectively eliminates fluctuations in the content or concentration of acidic substances present in the strongly acidified layer. Specifically:

[0124] S131. Obtain the acid substance detection sensor in each acid substance monitoring device group located in the strongly acidified layer, so as to obtain the sensor in the strongly acidified layer.

[0125] The purpose of this step is that, for the severely acidified soil layer, the content and concentration of acidic substances are more easily affected by various factors, such as precipitation and fertilization. Each fluctuation makes it difficult to effectively regulate the acidified soil according to the baseline application rate. Therefore, it is necessary to identify specific sensors within the severely acidified layer to lay the foundation for determining the fluctuation parameters.

[0126] Among them, sensors for detecting acidic substances within a strongly acidified layer are identified; these sensors are known as sensors within a strongly acidified layer.

[0127] S132. Obtain the depth of the sensor within the strongly acidified layer and obtain the measured concentration of acidic substances within the strongly acidified layer in real time to obtain the real-time concentration of acidic substances.

[0128] The purpose of this step is that, once the sensors within the strongly acidified layer are identified, the real-time concentration of acidic substances in the strongly acidified layer can be obtained based on these sensors. Based on this concentration, the dosage or rate of conditioner can be adjusted according to the fluctuation data of the acidic substance concentration.

[0129] Among these methods, the depth velocity of the sensor within each strongly acidified layer can be obtained, which can cope with the fluctuations in the concentration of acidic substances at different depths within the strongly acidified layer.

[0130] For each sensor within the strongly acidified layer, it is necessary to determine the concentration of acidic substances at the sensor's location.

[0131] For each sensor within the strongly acidified layer, it is necessary to obtain the concentration of acidic substances at different depths within the strongly acidified layer in real time in order to obtain the real-time concentration of acidic substances.

[0132] S133. Obtain the depth of the sensor in the severely acidified layer when the real-time concentration change rate of acidic substances is not lower than the preset change rate, and determine the area in the severely acidified layer where the application rate of soil acidification conditioner needs to be adjusted.

[0133] The purpose of this step is to determine whether fluctuations are small after obtaining the real-time concentration of acidic substances. These fluctuations do not need to be adjusted by changing the application rate of the soil acidification conditioner. Instead, they can be handled according to the baseline application rate. In other words, whether the fluctuations need to be adjusted requires additional analysis.

[0134] The preset change rate can be based on the experience of technicians or the average change rate of acidic substances in all sensors within the strongly acidified layer.

[0135] Once the sensor depth within the severely acidified layer and the preset change rate are determined, the sensor depth within the severely acidified layer where the concentration change rate is not lower than the preset change rate can be determined. This is equivalent to determining the depth of the severely acidified layer where the soil acidification conditioner application rate needs to be adjusted.

[0136] For all sensors within the severely acidified layer, it is necessary to identify all sensors whose real-time concentration change rate is not lower than the preset change rate. This directly yields all the areas where the application rate of soil acidification conditioner needs to be adjusted.

[0137] S134. Based on the real-time concentration change rate of the acidic substances, obtain the adjusted dosage of the soil acidification conditioner during the period of eliminating the concentration fluctuation of acidic substances in the severely acidified layer.

[0138] The purpose of this step is to determine the dosage of soil acidification conditioner during the elimination of acidity fluctuations.

[0139] Specifically, the real-time concentration change rate of acidic substances is obtained, and the real-time concentration change rate of acidic substances in the strongly acidified layer is obtained to determine the adjusted dosage within that layer depth. The equation is as follows:

[0140] ,

[0141] Among them, M hThis indicates the adjusted dosage of soil acidification conditioner within this depth level; M hs This indicates the initial dosage of soil acidification conditioner within this depth level; r h This represents the real-time concentration change rate of acidic substances.

[0142] The formula for determining the dosage of soil acidification conditioner within the specified depth is as follows:

[0143] ,

[0144] Where n represents the number of sensors within the strongly acidified layer.

[0145] The beneficial effect of step S130 is that it can fully determine the concentration fluctuation of acidic substances in the strongly acidified layer and adjust the dosage of soil acidification conditioner based on the fluctuation, thereby adjusting the concentration fluctuation of soil acidification conditioner in the strongly acidified layer to avoid insufficient soil conditioning effect caused by the fluctuation of soil acidification conditioner.

[0146] As described in step S140, the purpose of this step is that after a period of conditioning, the acid content of both the strongly acidified layer and the transition layer of the acidified soil will decrease. However, due to the differences in the physicochemical characteristics of the strongly acidified layer and the transition layer, such as differences in density, porosity, and microbial clusters, and although the acid content of the strongly acidified layer has decreased, it may still exceed the requirements for the crops to be planted. Therefore, it is necessary to use appropriate methods to dilute the acidic substances in the strongly acidified layer. The method used in this application is tillage. Specifically:

[0147] S141. After a soil conditioning cycle, the soil in the strongly acidified layer and the transition layer is tilled to obtain the mixed soil.

[0148] The purpose of this step is to simultaneously till the heavily acidified layer and the transition layer after a soil conditioning cycle, ensuring soil mixing.

[0149] The tillage depth can be set based on the total depth of the strongly acidified layer and the transition layer.

[0150] In some embodiments, after tilling the strongly acidified layer and the transition layer, other equipment is used to further homogenize the soil in both layers.

[0151] For land with a significant fallow period, such as the eastern mountainous area of ​​Northeast China, in order to improve the conditioning effect of acidified soil, especially when crop cultivation and acidified soil conditioning are carried out at the same time, and in plots that may involve straw returning to the field, it is necessary to plow after crop harvest. At this time, the strongly acidified layer and transition layer can be eliminated, and the content of acidic substances in the soil can be reduced from the root.

[0152] S142. Real-time acquisition of the concentration of acidic substances in the mixed soil to obtain the fluctuation amount of acidic substances in the mixed soil and the fluctuating soil layer.

[0153] The purpose of this step is that in many regions, in order to make better use of land resources, soil acidification conditioning and crop planting are carried out simultaneously. After the crops are harvested, the land is left fallow until the next farming season, when the land can be treated. During this process, various factors may cause the soil acidity to increase. Therefore, it is necessary to consolidate the acidification effect of the soil conditioning through concentration monitoring.

[0154] The concentration of acidic substances in the mixed soil is obtained in real time. The specific method for obtaining this concentration is the same as that mentioned in S110, and will not be repeated here.

[0155] Specifically, based on the sensor deployment depth in the acidic substance monitoring device group, the soil layer corresponding to the depth where fluctuations occurred, and the amount of acidic substance fluctuations in that soil layer are obtained.

[0156] S143. Obtain the amount of soil acidification conditioner required to eliminate the fluctuation of acidic substances in the mixed soil, and apply it to the fluctuating soil layer.

[0157] The purpose of this step is to eliminate the fluctuations in the total amount of acidic substances in the soil during that period, in order to maintain the conditioning effect on acidified soil, once it is determined that there have been fluctuations.

[0158] This requires continuous monitoring of the land even during the off-season, such as monitoring during the fallow period in the eastern mountainous areas of Northeast China, and eliminating fluctuations in acidic substances to ensure that the concentration of acidic substances in the soil does not increase during this period, thereby further improving the conditioning level.

[0159] The method for determining the dosage of soil acidification conditioner to be further applied within the fluctuating soil layer is the same as that for steps S120 to S130, and will not be repeated here.

[0160] The beneficial effect of step S140 is that it can ensure that after a soil acidification conditioning cycle, the soil is tilled and mixed evenly, and the concentration of acidic substances in the soil after tilling is monitored, thereby eliminating the fluctuations in the concentration of acidic substances, so as to continuously guarantee and consolidate the soil acidification conditioning effect achieved within a cycle.

[0161] As described in step S150, the purpose of this step is that, since the technical solution constructed in this application utilizes continuous soil acidification conditioning operations to comprehensively ensure the conditioning effect of acidified soil, in actual treatment, after one conditioning cycle, the acidified soil conditioning benchmark for the next cycle is determined. Specifically:

[0162] S151. Before the start of the next conditioning cycle, obtain the concentration of acidic substances in the soil for the next conditioning cycle.

[0163] The purpose of this step is to prepare the soil for the next conditioning cycle, which usually means the start of a new round of farming. Typically, this involves tilling the land, which further eliminates the difference in acid concentration between the strongly acidified layer and the transition layer in the soil. Therefore, soil conditioning is necessary based on this data.

[0164] Before the start of the next conditioning cycle, and after tilling, the concentration of acidic substances in the soil for the next conditioning cycle is obtained by directly using the acidic substance monitoring device group, which is set up, and the average value is calculated.

[0165] In some embodiments, the next conditioning cycle is during a fallow period, meaning that no tillage is carried out during a cultivation period. In this case, the next conditioning cycle simply represents the next fallow period, in which case tillage will obviously not be carried out. The concentration of acidic substances in the soil in the next conditioning cycle is equal to the concentration of acidic substances in the soil measured after the previous cycle.

[0166] S152. Based on the concentration of acidic substances in the soil during the next conditioning cycle and the target concentration of acidic substances after the end of the next conditioning cycle, obtain the total amount of soil acidification conditioner applied during the next conditioning cycle to obtain the baseline amount of soil acidification conditioner applied.

[0167] The purpose of this step is to determine the dosage of soil acidification conditioner for the next conditioning cycle based on the concentration of acidic substances in the soil after obtaining this information, and then to apply the conditioner accordingly.

[0168] The total amount of soil acidification conditioner to be applied was determined based on the entire soil layer.

[0169] In this process, the concentration of acidic substances in the soil during the next conditioning cycle is uniformly distributed. Therefore, by multiplying the average concentration of acidic substances in the soil before the start of the next conditioning cycle by the volume of soil within the coverage area of ​​the acidic substance monitoring device group, the content of acidic substances in the soil before the official start of the next conditioning cycle can be obtained.

[0170] The target concentration of acidic substances after the next conditioning cycle is obtained is multiplied by the soil volume within the coverage area of ​​the acidic substance monitoring device group to obtain the allowable content of acidic substances in the soil after the next conditioning cycle is completed.

[0171] Specifically, the difference between the acid content in the soil before the start of the next conditioning cycle and the allowable acid content in the soil after the completion of the next conditioning cycle is obtained, and the dosage of the benchmark soil acidification conditioner is determined based on this difference. The specific dosage equation is the same as the equation in step S122, and will not be repeated here.

[0172] The beneficial effect of step S150 is that, after a conditioning cycle of acidified soil, the amount of soil acidification conditioner to be applied in the next conditioning cycle can be obtained based on the concentration of acidic substances after soil conditioning.

[0173] As described in step S160, the purpose of this step is to address the fact that in many regions, soil is affected by fertilizers, pesticides, and natural rainfall during a single farming season, leading to the rapid formation of acidic substances on the soil surface. This creates a new cycle of intense acidification, and conversely, a new cycle of transitional layer is also formed. The changes in acidity, conditioning methods, and conditioning priorities of these two layers are clearly different; therefore, it is necessary to remeasure both the intense acidification layer and the transitional layer within the new cycle. Specifically:

[0174] S161. Based on the acidic substance monitoring device group, obtain the concentration of acidic substances in the soil in the vertical direction during the next conditioning cycle.

[0175] The purpose of this step is to obtain the concentration of acidic substances in the soil in the vertical direction during the next conditioning cycle, and to lay the foundation for the subsequent identification of the strongly acidified layer and transition layer based on the changes in concentration.

[0176] Among them, the acid substance monitoring device group is used to continuously and in real time obtain the concentration of acid substances obtained by each sensor in the next conditioning cycle.

[0177] Obviously, in measuring the concentration of acidic substances, it is also necessary to simultaneously obtain the depth of the sensor, which is equivalent to obtaining the real-time concentration of acidic substances at different depths.

[0178] S162. Obtain adjacent sensors in the acid substance monitoring device group whose acid substance concentration difference is not lower than the preset difference for the next conditioning cycle, so as to obtain the strong acidification layer and transition layer for the next conditioning cycle.

[0179] The purpose of this step is to obtain information on the strongly acidified layer and transition layer within a new conditioning cycle based on the concentration of acidic substances in the soil in the vertical direction after obtaining the data.

[0180] The method for obtaining the strongly acidified layer and transition layer in the next conditioning cycle is the same as the method disclosed in step S110, and will not be repeated here.

[0181] In some embodiments, considering that the concentration of acidic substances in a strongly acidified layer will produce a greater fluctuation effect, while the concentration of acidic substances in a transition layer hardly fluctuates or is in a state of continuous, slow and stable decrease in acidic substance concentration, the strongly acidified layer and the transition layer can be decomposed according to the fluctuation effect of acidic substance concentration. That is, soil layers that can produce a greater fluctuation effect are directly identified as strongly acidified layers, and soil layers that hardly fluctuate or are in a state of continuous, slow and stable decrease in acidic substance concentration are identified as transition layers.

[0182] Furthermore, the reason for re-evaluating the strongly acidified layer and the transition layer is that the soil porosity, moisture content, and other properties change after tillage and a new round of land cultivation, and the thickness of the two layers may also change, thus requiring re-evaluation.

[0183] The beneficial effect of step S160 is that it fully considers the strong acidification layer and transition layer that may be generated in the soil during the cultivation period under the influence of various activities in the natural environment or agricultural production. In other words, it fully considers the actual changes in the soil to ensure that the strong acidification layer can be conditioned at a high level in the subsequent soil conditioning process, while the transition layer does not need to be adjusted at high frequency, thereby reducing the energy consumption of the control system during the conditioning process.

[0184] As described in step S170, the purpose of this step is to ensure that, in the next conditioning cycle, the concentration of acidic substances in the transition layer will steadily decrease as the amount of soil acidification conditioner applied increases, and that the amount of soil acidification conditioner applied to the transition layer can be stable and continuous. Therefore, in specific treatments, it is necessary to determine the measured concentration of acidic substances in the transition layer during the next conditioning cycle, and use this data as the basis for comparison of specific conditioning states. Specifically:

[0185] S171. Based on the baseline soil acidification conditioner dosage and the duration of the next conditioning cycle, obtain the soil acidification conditioner dosage rate for the next conditioning cycle to obtain the baseline dosage rate.

[0186] The purpose of this step is to ensure that, for the formed strongly acidified layer and transition layer, the latter is stabilized and continuously adjusted by soil acidification conditioners, and the transition layer is usually not greatly affected by changes in the concentration of acidic substances in the strongly acidified layer. Therefore, the application rate of the benchmark soil acidifier can be directly used as the application rate of the transition layer.

[0187] The ratio between the baseline soil acidification conditioner dosage and the duration of the next conditioning cycle is used to obtain the baseline dosage rate.

[0188] The benchmark application rate can be directly used as the application rate of the soil acidification conditioner in the transition layer during the next conditioning cycle.

[0189] S172. According to the benchmark application rate, continue to apply soil acidification conditioner to the transition layer of the next conditioning cycle.

[0190] The purpose of this step is to continuously apply soil acidification conditioner into the transition layer during the next conditioning cycle in order to condition the acidified soil in the transition layer.

[0191] The obtained baseline application rate can be directly used as the rate at which soil acidification conditioner is continuously applied in the transition layer of the next conditioning cycle.

[0192] S173. After the start of the next conditioning cycle, obtain the concentration of acidic substances in the transition layer of the next conditioning cycle in real time.

[0193] The purpose of this step is to monitor the concentration of acidic substances in the transition layer in real time once the transition layer has been conditioned, so as to use the target value for adjusting the strongly acidified layer.

[0194] In the transition layer based on the next conditioning cycle, the sensors in the acidic substance monitoring device group detect the concentration of acidic substances.

[0195] To obtain the concentration of acidic substances, the average value of the concentrations obtained from multiple sensors can be calculated.

[0196] In some embodiments, the soil acidification conditioner used in the transition layer may also differ in cost or type from the soil acidification conditioner used in the strongly acidified layer.

[0197] The beneficial effect of step S170 is to stabilize and continuously condition the transition layer of acidified soil in the next conditioning cycle, and at the same time obtain the concentration of acidic substances, so as to obtain the concentration of acidic substances in the transition layer of soil in the next conditioning cycle, and thus obtain the baseline value of the concentration of acidic substances in the strongly acidified layer in each conditioning cycle.

[0198] As described in step S180, the purpose of this step is to condition the acidified soil in the strongly acidified layer during the next conditioning cycle. Specifically:

[0199] S181. Real-time acquisition of the measured concentration of acidic substances in the strongly acidified layer during the next conditioning cycle.

[0200] The purpose of this step is to continuously and in real-time obtain the concentration of acidic substances in the strongly acidified layer during the next conditioning cycle. Based on the numerical values, the fluctuation of acidic substance concentration within this cycle can be determined. Furthermore, the dosage of soil acidification conditioner per unit time can be adjusted based on the fluctuation. In other words, based on the measured acidic substance concentration, the foundation is laid for subsequent dosage adjustment work.

[0201] In the case of a strongly acidified layer, all sensors in the strongly acidified layer are acquired for the next conditioning cycle, and the average concentration of acidic substances is obtained. Then, based on this average, the amount of acidic substances that need to be adjusted in the next time period is obtained, which can be directly obtained by multiplying the average concentration and the soil volume.

[0202] In some embodiments, the measured concentration of acidic substances obtained by each sensor in the strongly acidified layer is obtained to obtain the concentration of acidic substances at the depth of each sensor, and the soil acidification conditioner dispenser hole position at the depth of the sensor is determined, and then the hole position of the strongly acidified layer at that depth is adjusted based on the hole position.

[0203] S182. Obtain the concentration of acidic substances in the transition layer during the next conditioning cycle when applying soil acidification conditioner based on the benchmark application rate.

[0204] The purpose of this step is to determine the baseline value for the concentration of acidic substances in the strongly acidified layer based on the concentration of acidic substances in the transition layer during the next conditioning cycle.

[0205] Specifically, the concentration of acidic substances in the transition layer of each acidic substance monitoring device group within the next conditioning cycle is obtained by acquiring the sensor and the concentration of acidic substances acquired by the sensor in the transition layer, and the average value is calculated to obtain the concentration of acidic substances in the transition layer within the next conditioning cycle.

[0206] Specifically, regarding the concentration of acidic substances in the strongly acidified layer and the transition layer, it is necessary to ensure that the concentrations of acidic substances obtained in these two layers are acquired at the same point in time.

[0207] S183. Based on the difference between the measured concentration of acidic substances and the concentration of acidic substances in the transition layer during the next conditioning cycle, the amount of soil conditioner applied in the severely acidified layer during the next conditioning cycle is adjusted in real time, so that the concentration of acidic substances in the severely acidified layer during the next conditioning cycle is the same as the concentration of acidic substances in the transition layer during the next conditioning cycle.

[0208] The purpose of this step is to measure the concentration of acidic substances in the severely acidified layer in real time, and, once the baseline concentration to be achieved in the severely acidified layer is determined, the amount of soil acidification conditioner to be applied in the severely acidified layer can be adjusted based on the difference in the concentration of acidic substances between the two soil layers.

[0209] The calculation involves determining the difference in acidic substance concentration between the strongly acidified layer and the transition layer at the same time point. This difference represents the soil conditioning target that the strongly acidified layer needs to achieve.

[0210] After obtaining the difference, the amount of soil acidification conditioner required to eliminate the difference is determined by directly using the soil acidification conditioner value required to eliminate 1 unit of acidic substances in the soil during the elimination of acidic substances. This value indicates the additional amount of soil acidification conditioner required to eliminate the severely acidified layer.

[0211] The beneficial effect of step S180 is that it can ensure that after the next conditioning cycle, in addition to ensuring that the total amount of acidic substances in the soil decreases, it can also ensure that the concentration of acidic substances in the strongly acidified layer and the transition layer is similar to the greatest extent. This will prevent the concentration of acidic substances in the two layers from being too different during subsequent tillage, which would lead to an increase in the concentration of acidic substances in the transition layer after tillage, thereby weakening the conditioning effect of acidified soil.

[0212] After each cycle of soil acidification conditioning is completed, there may be situations where the target is not achieved, such as when rainfall occurs at the end of the conditioning cycle. In such cases, further soil conditioning is required. Specifically:

[0213] S184. After each soil acidification conditioning cycle is completed and the soil is tilled, obtain the concentration of acidic substances in the soil after tilling.

[0214] The purpose of this step is to obtain the concentration of acidic substances in the soil after tilling in order to obtain a baseline value.

[0215] One method involves obtaining the concentration of acidic substances in the soil after tilling.

[0216] For the concentration of acidic substances, the average value of the acidic substance concentration obtained by all the sensors can be directly obtained, and this average value can be used as the concentration of acidic substances in the soil after tilling.

[0217] S185. Based on the comparison between the concentration of acidic substances in the soil after tilling and the preset concentration of acidic substances in the soil after tilling, the dosage of the benchmark soil acidification conditioner for the next conditioning cycle is adjusted according to the comparison results.

[0218] The purpose of this step is to address situations where preset parameters are not met after tilling has been completed, based on the obtained measurement results, so that the concentration of acidic substances in the pattern reaches the standard.

[0219] Among them, the preset acid concentration parameter in the soil after tillage can be equivalent to the acid concentration target during the conditioning cycle.

[0220] When it is found that the concentration of acidic substances in the soil after tillage is higher than the preset concentration of acidic substances in the soil, the difference between the two data is obtained, and then the amount of soil acidification conditioner to be added is obtained. The specific calculation method is the same as that in step S122, and will not be repeated here.

[0221] If the concentration of acidic substances in the soil after tilling is found to be no higher than the preset concentration of acidic substances in the soil, then there is no need to supplement the soil acidification conditioner.

[0222] The technical solution of this application includes the following operational process: Before the first application of soil acidification conditioner, the initial strongly acidified layer and transition layer are determined; based on the initial acidic substance concentration of the strongly acidified layer and transition layer, and the set target for this cycle, the application amount of conditioner for the two layers is determined; during the formal conditioning process, based on the fluctuation of acidic substances in the strongly acidified layer, the application amount is adjusted according to the set application amount of conditioner for the strongly acidified layer; at the end of the soil acidification conditioning cycle, the strongly acidified layer and transition layer are tilled; after tilling, the concentration of acidic substances in the soil is compared with the preset concentration, and soil acidification conditioning is performed; the concentration of acidic substances in the soil is protected after tilling before the start of the next cycle; soil tilling is performed before the formal start of the next cycle; the baseline acidic substance application amount for the next cycle is determined; the strongly acidified layer and transition layer are determined after the start of the next cycle; the application amount of soil acidification conditioner for the strongly acidified layer is adjusted in real time after the start of the next cycle; ensuring that the concentration of acidic substances in the strongly acidified layer and transition layer is the same in the next cycle.

[0223] The beneficial effects of this application include:

[0224] 1. Improved soil conditioning efficiency. The technical solution of this application obtains a strongly acidified layer and a filter layer in acidic soil. Different methods of applying soil acidification conditioners are used for the two layers, which improves the conditioning efficiency of the strongly acidified layer. After that, these two layers are tilled. Based on the tilling operation, the total content of acidic substances in the soil above the base layer can be reduced. Under the most ideal conditions, the acidic soil can be thoroughly conditioned within one cycle.

[0225] 2. Improved soil conditioning effect. In the technical solution of this application, the soil to be conditioned is divided into a severely acidified layer and a transitional layer. Different conditioning schemes are adopted for the two layers. The former is conditioned with soil acidification conditioner applied based on actual measurement results, which greatly improves the conditioning effect. For the transitional layer, since the acid content is relatively stable and low, a stable conditioner application scheme can be used for treatment. This ensures that the acid content in the soil of the severely acidified layer decreases at a higher rate and can cope with various possible fluctuations. Ultimately, it ensures that the acid content in the severely acidified layer decreases continuously, stably and effectively. Overall, the soil conditioning effect is improved.

[0226] 3. Improved stability of soil conditioning effects. During soil conditioning, various changes may occur in the natural environment. For example, rainfall may introduce more acidic substances into the soil. Therefore, it is necessary to improve the stability of soil conditioning levels to maintain the conditioning quality of acidic soils. In this application's technical solution, the acid content of the strongly acidified layer is monitored in real time. Based on the real-time monitoring results, the application rate of the soil acidification conditioner can be adjusted in real time to ensure the stability of the soil conditioning effect.
