Description

Technical Field

[0001] This application belongs to the field of facility agriculture technology, specifically, it relates to an environmental adjustment method for the root zone soil of black soil. Background Technology

[0002] Black soil, as an important agricultural resource, is inherently highly fertile. However, due to factors such as climate, improper fertilization, and overcultivation over the years, significant problems of soil clumping and insufficient fertility have emerged in the root zone, leading to reduced crop yields. Furthermore, these clumping and fertility deficiencies are not evenly distributed across the land but are scattered and fragmented, making targeted and quantitative adjustments to the soil environment within the black soil root zone difficult. Current technologies, whether for removing clumping or adjusting fertility in the black soil root zone, employ comprehensive land adjustments, such as large-scale uniform plowing and straw return. The problems with existing technologies are: 1) Inability to achieve personalized control. The areas requiring environmental adjustment in the black soil root zone are often scattered and fragmented. Problematic areas require independent and personalized environmental control, which is difficult to achieve using generalized treatment methods. 2) Difficulty in achieving efficient control. Currently, the commonly used environmental conditioning methods involve adding environmental conditioning agents into sprinkler and drip irrigation systems. These agents need to infiltrate into the soil surface, which reduces their effectiveness and results in excessive losses. This makes it difficult to achieve efficient regulation of the soil environment, especially the internal environment of the soil layer, in the root zone of black soil.

[0003] In summary, how to achieve personalized and efficient regulation of the soil environment in the root zone of black soil is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0047] The new black soil agglomeration improver was applied, and the nutrient application data was adjusted until the volume of black soil agglomerates that were affecting crop growth decreased to a level that did not affect crop growth.

[0048] The beneficial effects of this application include:

[0049] 1. Personalized environmental adjustment is achieved. In the technical solution of this application, the black soil clumps in the root layer of black soil are monitored. Based on the monitoring results, the parameters for the application of the amendment for the black soil clumps are determined, thereby achieving personalized improvement. At the same time, the root layer clump information is also analyzed during the crop cultivation process. Based on the analysis results, further environmental adjustments can be made based on the monitoring results, thereby achieving personalized environmental adjustment throughout the entire process.

[0050] 2. Highly efficient environmental adjustment is achieved. In the technical solution of this application, the adjustment of black soil clumps within the black soil root layer and the nutrient supply process for crops are carried out by directly applying soil conditioners or nutrients to the black soil clumps and crop roots, thereby directly adjusting the environment of the black soil root layer and improving the efficiency of environmental adjustment. In addition, during the nutrient environment adjustment, the nutrient supply and whether and how much soil conditioner is applied are adjusted in real time according to the root distribution of the crops, thus fully improving the efficiency of environmental adjustment of the black soil root layer.

[0051] 3. Environmental adjustment throughout the entire process is achieved.

At the same time, during the crop growth period, soil compaction and fertility parameters, as well as crop growth status, are continuously tracked and analyzed. Based on the tracking and monitoring results, nutrients and black soil compaction improvers are added to the soil, thereby ensuring that environmental adjustment is carried out continuously from before planting to the entire growth period of the crop, thus achieving environmental adjustment of the black soil root layer soil throughout the entire crop planting process.

[0055] Figure 3 The nutrient delivery device arrangement is intended for use in an environmental adjustment method for the root zone soil of black soil provided in this application embodiment. Detailed Implementation

[0056] 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.

[0057] In the environmental adjustment of the root zone soil in black soil, the direct underground adjustment method theoretically has advantages such as reducing wasteful resource consumption and lowering input costs, especially in nutrient supply. However, this method can easily lead to "bad clumps" in the underground soil layer, which can affect crop growth. Therefore, this situation needs to be avoided or treated. Furthermore, various factors can cause clumps to exist in the underground space. These clumps can also be treated by directly applying soil conditioners, but this method may not always resolve the clumping problem. Therefore, the purpose of this application is to address the potential problems while ensuring the advantages of applying nutrients and conditioners underground, thereby fully realizing personalized, efficient, and comprehensive adjustment of the black soil root zone environment.

[0058] To address the problems existing in the prior art, this application discloses a method for environmental adjustment of the root zone soil in black soil, such as... Figure 1 The diagram shown is a flowchart of an environmental adjustment method for the root zone soil of black soil provided in an embodiment of this application. Specifically:

[0059] S110. After tilling, obtain the depth range of the black soil root layer and the state of black soil clods within the depth range.

[0060] S120. Based on the black soil agglomeration state, prepare a black soil agglomeration improver.

[0061] S130. Based on the black soil clotting agent dispenser, inject the black soil clotting agent into the root zone of the black soil. S140. Set up a nutrient dispenser in the root zone of the black soil and apply base fertilizer.

[0062] S150: Monitors crop status in real time throughout the crop growth cycle and determines crop nutrient requirements.

[0063] S160. Based on the root distribution of the crop, nutrients are delivered to different root depths.

[0064] S170. Monitor the soil root layer compaction status during crop growth and apply soil compaction improver during crop growth.

[0065] The beneficial effect of the above steps is that, by using the measured data on the clumping and nutrients in the black soil root layer, corresponding agents can be provided into the soil layer, thereby directly adjusting and treating the environment of the black soil root layer, so as to achieve personalized, efficient and whole-process adjustment of the black soil root layer environment.

[0066] The following will provide a detailed explanation of all the steps above:

[0067] As described in step S110, the purpose of this step is to identify all black soil clumps within the entire black soil root layer during the adjustment process. While tilling can largely eliminate soil compaction, it cannot guarantee the removal of all clumps. Furthermore, these black soil clumps in the root layer can easily disturb planted crops. Therefore, it is necessary to identify all black soil clumps within the entire depth range of the black soil root layer. Specifically:

[0068] S111. Obtain the tillage depth of the black soil root layer to obtain the depth range of the black soil root layer.

[0069] The purpose of this step is to comprehensively promote the adjustment and protection of black soil resources, in order to repair the problems caused by abnormal use of black soil over the past years, such as acidification of the black soil subsoil and shallowing of the topsoil. During the repair process, it may include breaking up the plow pan and returning straw to the field in multiple layers. Although these operations are effective and are adjusted according to the actual condition of the soil, they will result in different depth ranges of the black soil root system. In order to ensure the effect, it is necessary to determine the depth range of the black soil root system.

[0070] In this process, each region of the black soil root system is tested, and the test results obtained represent the depth range of the black soil root system.

[0071] In determining the depth range of the root system layer in black soil, various detection devices can be used, such as rigid rod insertion into the soil for detection, radar or ultrasonic detection, etc. The specific method is not limited in this application.

[0072] In the detection of the depth range of the root system layer in black soil, all depth range detection results need to be labeled, and this detection needs to cover all land areas to achieve full-range detection.

[0073] If detection points with similar root depths in the black soil are all set up in the same plot area, then crop varieties can be selected within the plot based on the root depth of the black soil and the root depth of various crops.

[0074] In some embodiments, the soil depth that can be directly determined can be used as the depth range data of the black soil root layer.

[0075] S112. Test the soil within the depth range of the root layer to obtain the state of black soil clotting within the depth range of the black soil root layer.

[0076] The purpose of this step is to detect the clumps in the root layer of black soil in different plots and areas, and then to perform preliminary processing based on the detected clump information.

[0077] Specifically, for each plot within the depth range of the black soil root system layer, the black soil clumps within it are detected.

[0078] Among them, ultrasonic testing, radar testing, and observation of clumps during the tillage process can be used to detect black soil clumps.

[0079] In the detection of the clod state, it is also necessary to detect various factors such as the hardness, size, and volume of the black soil clods in order to obtain all the information on the state of the black soil clods.

[0080] In addition to recording the location information of the black soil clumps within the black soil root layer that have been detected, it is also necessary to determine the location of the black soil clumps that need to be treated.

[0081] The beneficial effect of step S110 is that by determining the depth range of the black soil root layer, the plot can be identified, and the state information of the black soil clumps can be accurately determined. In this case, in the subsequent specific preliminary treatment of black soil clumps, fixed-point and quantitative treatment can be carried out to improve the preliminary treatment level of black soil clumps.

[0082] As described in step S120, the purpose of this step is to address the differences in soil conditioners used for different types of black soil clumps during the treatment of black soil clumps within the root zone. For example, the soil conditioners used to dissolve black soil clumps differ depending on whether the clumps are caused by clay soil or water and fertilizer imbalance. Therefore, it is necessary to adjust the black soil clump conditioner accordingly. Specifically:

[0083] S121. Based on the state of black soil caking, obtain the caking blocks that need to be processed.

[0084] The purpose of this step is to specifically determine the state of black soil clumps within the black soil root layer. Then, based on these parameters, it is necessary to select the black soil clumps that need to be treated.

[0085] Among these steps, the information on the state of black soil clogging is determined, and then it is analyzed whether this information will have a negative impact on crop growth.

[0086] The negative impacts include the hardness of the clumps, the pH level of the clumps, and the effect of the clumps on the root system's coverage area.

[0087] Among them, black soil clumps that can cause an impact are identified as clumps that need to be treated, while other black soil clumps do not need to be treated.

[0088] Specifically, the location of each black soil block that needs to be treated is marked, and the specific state of the black soil block is determined, including the cause of the black soil block, the size of the black soil block, the depth of the black soil block, etc., so as to mark the state information of the block object that needs to be treated.

[0089] S122. Based on the formation cause and structure of the object to be processed, configure a black soil agglomeration improver.

[0090] The purpose of this step is to adjust the black soil clumps in the root layer of black soil that needs to be treated, and to select the appropriate black soil clump improver based on the actual state parameters of these clump formations. Then, the improver can be used to dissolve the black soil clumps.

[0091] This involves obtaining the causes and structure of agglomerates, analyzing the particle types, internal strength, and structural stratification information of black soil agglomerates, in order to determine the specific causes and structure of the agglomerates.

[0092] In this process, based on the ion type of black soil agglomerates, the ion type of the amendment used in the black soil agglomeration treatment process is determined, and the black soil agglomeration amendment is prepared accordingly.

[0093] In the use of soil conditioners, microbial resources that can treat black soil caking can be placed in the conditioner, and then black soil caking can be treated based on these microorganisms.

[0094] In this application, both the nutrient configuration and the treatment of black soil clotting are based on the application of a liquid dispensing device buried in the root layer of black soil. Therefore, it is necessary to ensure that the concentration of the black soil clotting improver is low in order to avoid the formation of clotting in the root layer of black soil when a high concentration of improver is applied.

[0095] The specific configuration of the black soil agglomeration improver is determined and configured based on the types of black soil agglomeration improvers already recorded in the information system, in order to process the agglomeration objects.

[0096] The beneficial effect of step S122 is that, before the specific cultivation of black soil, the black soil clumps that need to be eliminated in the root layer of black soil are screened and the amendment is prepared. Then, the black soil clumps can be specifically treated according to the selected amendment to avoid the black soil clumps causing significant negative impact on crop growth.

[0097] As described in step S130, after identifying the black soil clotting improver, it needs to be applied to the root zone of the soil before planting to pre-treat black soil clotting within the root zone. Specifically:

[0098] S131. The black soil agglomerate improver dispenser is inserted into the soil layer and comes into contact with the agglomerates that need to be treated.

[0099] The purpose of this step is that after obtaining the black soil clotting amendment, a special black soil clotting amendment dispenser is needed to apply the amendment underground. Therefore, the device needs to be able to be inserted into the root layer of the black soil.

[0100] Once the black soil clumps are identified and their status information is determined, the soil is directly inserted into the soil.

[0101] This process involves marking the locations of all black soil clumps, inserting a dispenser into the soil, and then using the device to apply the soil conditioner.

[0102] Specifically, the black soil agglomerate dispenser needs to be inserted vertically into the soil, with the outlet in direct contact with the black soil clumps. If necessary, the black soil clumps can be inserted directly into the soil. For example... Figure 2 The diagram shows the arrangement of a black soil clotting amendment dispenser for an environmental adjustment method of black soil root zone provided in this application embodiment. The elliptical part represents a large volume of black soil clods. The black soil clotting amendment dispenser structure has multiple openings. A filter screen is provided at the top opening of the part inserted into the black soil clod to prevent soil from entering and clogging. An opening is provided on the side wall of the tip structure inserted into the black soil clod, and a filter screen is also provided inside it. The amendment can be released by the outward permeation of the black soil clotting amendment through these openings.

[0103] Among them, the top structure of the black soil agglomerate dispenser has various types. The simplest is a single hole, and an anti-clogging mesh is installed in the hole to prevent clogging. The more complex type has multiple holes in the top part, and an anti-clogging mesh is installed in each hole. This complex black soil agglomerate dispenser is suitable for direct insertion into large-volume black soil agglomerates.

[0104] S132. Based on the state parameters of the agglomerates that need to be treated, obtain the dosage and application pressure of the corresponding black soil agglomerate improver.

[0105] The purpose of this step is, after determining the state parameters requiring treatment of agglomerates, to adjust the application pressure of the amendment, and if necessary, use water pressure to impact and break up the agglomerates of black soil; otherwise, agglomeration treatment is performed solely based on the amendment. Specifically:

[0106] S1321. Based on the state parameters of the agglomerates that need to be treated, obtain the placement location of the corresponding black soil agglomerate amendment within the agglomerates that need to be treated.

[0107] The purpose of this step is to understand that different black soil clumps have different characteristics, and the optimal placement of the clump improver also varies depending on the type of clump. Therefore, this information needs to be considered when making the decision.

[0108] The so-called state parameters that need to be addressed for soil clumping include various information such as the hardness, volume, density, and liquid absorption capacity of the soil clumps.

[0109] The so-called placement location of the black soil clod amendment within the clods to be treated refers to the position of the agent placement hole of the black soil clod amendment dispenser during the application process. This includes situations such as merely contacting the black soil clods, shallowly inserting into the black soil clods, and inserting into the center of the black soil clods. Essentially, this corresponds to the relative position of the amendment placement hole and the black soil clods.

[0110] The process involves determining the location of the amendment injection hole in the black soil agglomerate dispenser based on obtained state parameters such as hardness and liquid absorption capacity. This process can be based on specific standard plans or technical requirements, or it can be based on the experience of professional technicians. For example, if a black soil agglomerate is large in volume, has high hardness and density, and low liquid absorption capacity, simply relying on external application of the amendment and slow dissolution of the agglomerate is unlikely to be effective. Therefore, the amendment injection hole of the black soil agglomerate dispenser needs to be deeply inserted into the black soil agglomerate, and high pressure applied to impact and break up the agglomerate. However, for black soil agglomerates that are soft and small in volume, high-pressure impact breaking should not be used to avoid spraying too much amendment, which could cause the amendment to become a new catalyst for the formation of black soil agglomerates. In essence, determining the injection location can be done based on reasonable rules or requirements.

[0111] S1322. Based on the application location, obtain the application pressure of the black soil agglomeration improver.

[0112] The purpose of this step is to break up black soil clumps by impact if the material is hard. However, if the material is not hard, this method will deteriorate the soil environment. Therefore, it is necessary to determine the appropriate method for applying the soil amendment.

[0113] Once the placement location has been determined, the state of the black soil clumps can be determined, i.e., whether pressure is needed to break up the structure.

[0114] When the application location is found to be inside a black soil clump, the application pressure of the amendment needs to be set to a pressure that can cause the black soil clump to be broken by impact.

[0115] In determining the injection pressure of the modifier, a pulse injection method should be used, that is, the modifier should be injected in one or more impacts to improve the impact effect.

[0116] The specific process for determining the impact pressure can be based on a record table generated after laboratory testing, and then the pressure can be determined based on the data recorded in the record table.

[0117] When the application location is not inside the black soil clumps, the application pressure of the black soil clump improver does not need to be too high. It is sufficient to ensure that the improver can seep out from the dispenser and penetrate into the black soil clumps.

[0118] S1323. Obtain the volume of the clumps that need to be treated and obtain the dosage of the corresponding soil clump amendment.

[0119] The purpose of this step is to address the fact that if the amount of soil amendment applied is excessive, especially if it exceeds the soil's carrying capacity, the amendment itself becomes a significant cause of black soil clumping. Therefore, the amount of soil amendment applied needs to be controlled during the treatment process.

[0120] The specific dosage can be determined based on the experience of professionals and laboratory tests, to determine the amount of amendment required to dissolve black soil clumps during treatment with the corresponding amendments for different types of black soil clumps.

[0121] Among them, the volume of the clumps that need to be processed is actually a kind of state parameter. All state parameters can be obtained by means of ultrasonic waves, radar, rigid rod drilling, etc. For example, for volume, black soil clumps can be identified as spherical structures instead of non-uniform structures. After the diameter is measured, the volume is calculated.

[0122] Specifically, the volume of the clumps to be treated is determined, the corresponding amount of soil clump amendment to be applied is calculated, and the amendment is applied accordingly.

[0123] S133. Based on the dosage and application pressure of the corresponding black soil caking amendment, inject the black soil caking amendment into the root zone soil of the black soil.

[0124] The purpose of this step is to execute the action after obtaining the numerical information on the dosage of the improver.

[0125] Among them, based on Figure 2The black soil agglomerate dispensing device shown dispenses the calculated black soil agglomerate dispensing agent to perform impact crushing of black soil agglomerates and direct dissolution based on the dispensing agent.

[0126] Considering that the dissolution process of the soil conditioner in black soil requires a certain amount of time, the application time of the soil conditioner should be determined according to the crop planting time and the dissolution time of the black soil clumps.

[0127] The dosage of black soil agglomerate improver is defined as the total amount of black soil agglomerate improver that needs to be applied to the black soil agglomerate within a black soil agglomerate dissolution cycle.

[0128] The beneficial effect of step S130 is that the black soil clumps can be identified before the black soil is cultivated, and the amount and pressure of the black soil clump improver can be determined based on the characteristics of the black soil clumps. The black soil clumps can be dissolved before cultivation based on these two values.

[0129] As described in step S140, the purpose of this step is to prepare the black soil for crop planting. An important task at this stage is to apply base fertilizer to the root zone of the black soil to adjust the environment and provide nutrients. Specifically:

[0130] S141. After applying the black soil clotting improver, conduct real-time monitoring of the black soil root layer.

[0131] The purpose of this step is to monitor the actual effects achieved after the application of the black soil caking improver to determine whether the current treatment effect can be directly applied to crop planting.

[0132] After applying the black soil clotting improver, it is necessary to monitor the state of black soil clotting within the root zone in real time, or periodically or irregularly.

[0133] In particular, after applying the black soil compaction improver, it is necessary to ensure that the black soil compaction will not affect crop growth before planting crops on the land.

[0134] This requires recording the black soil clumping information after each measurement and comparing it with the standard values.

[0135] When the black soil clods are found to be inconsistent with the preset standards, the application parameters of the black soil clod amendment need to be adjusted. The adjustment process is carried out in accordance with the methods in steps S120 to S130, so as to adjust the application parameters such as the type of soil amendment, application pressure and application amount accordingly, so as to improve the treatment quality.

[0136] S142. When the black soil clumps in the root zone meet the requirements for farming, a nutrient delivery device is installed in the black soil root zone.

[0137] The purpose of this step is to improve the quality of nutrient supply, especially to enhance the nutrient absorption efficiency of the root system. It is necessary to set up a corresponding nutrient delivery device to supply nutrients to the root layer of black soil.

[0138] Among these, the obtained information on the root system of black soil needs to be analyzed to determine whether the state of black soil clotting affects crop planting.

[0139] To determine whether black soil clumps meet agricultural requirements, it is necessary to analyze the size, hardness, and types of ions contained in the black soil clumps.

[0140] This process involves treating the black soil clumps, measuring their condition, and determining whether the land is suitable for crop cultivation only when all condition parameters meet the requirements for farming.

[0141] When it is determined that the black soil clumping meets the requirements for farming, nutrient delivery devices need to be installed in the root zone of the black soil, such as... Figure 3The diagram illustrates the intended use of a nutrient dispenser in a method for environmental adjustment of the root zone soil in black soil, as provided in this application embodiment. Multiple nutrient supply pipes are included, each transporting different types of nutrients, such as water-based nitrogen fertilizer, water-based phosphorus fertilizer, water-based potassium fertilizer, and micronutrient fertilizer. Water pipes are also included. Each pipe is connected to a nutrient input pipe, which in turn inputs nutrients from each nutrient supply pipe into the nutrient dispenser. A nutrient flow controller is installed between the nutrient dispenser and the nutrient supply pipes. This controller includes a flow valve and a flow valve opening angle adjustment system. The former adjusts the nutrient flow rate from the supply pipes to the dispenser, while the latter adjusts the flow rate by adjusting the flow valve. Each nutrient input pipe can also be connected to a water pipe to adjust the nutrient concentration. For the nutrient dispenser, its direct... Inserted into the root layer of black soil, the nutrient dispenser has multiple nutrient dispensing holes. The exterior of each hole is directly embedded in the soil, while the interior connects to all nutrient input pipes. This means that each nutrient dispensing hole can supply all nutrient types included in the entire nutrient supply pipeline group. The nutrient flow controller can directly receive the crop's nutrient requirements and automatically adjust the nutrient dispensing value. Furthermore, soil layer division needs to be based on the crop's root density, which places higher demands on the type of nutrient dispenser. If this type of dispenser is not supported, division can be based directly on the depth of the nutrient dispensing holes, assuming all roots within that soil layer require nutrient supply. It should be noted that each nutrient dispenser is adjacent to a crop plant, or multiple dispensers are evenly distributed around each crop plant to form a nutrient dispenser group surrounding the plant, ensuring uniform nutrient supply.

[0142] S143. Obtain the environmental conditions at the depth of the dispensing hole in the nutrient dispenser, adjust the output base fertilizer concentration and total amount of the dispensing hole, and dispense the base fertilizer.

[0143] The purpose of this step is to apply base fertilizer after the nutrient dispenser has been set up.

[0144] Among the factors considered in the application of base fertilizer, the main influencing factor is the nutrient supply to the crop from germination to tillering. Therefore, this factor needs to be taken into account when applying nutrients.

[0145] Among them, the type of crop to be planted in the plot is determined based on the nutrient distribution in the root layer of black soil.

[0146] Nutrients are supplied by a nutrient dispenser based on the nutrient requirements of the crop type during its initial growth period.

[0147] Among them, base fertilizer is applied according to the nutritional needs of different black soil root layers during crop growth, especially the top part of the black soil root layer, during the germination and initial growth stages of the crop.

[0148] The concentration of base fertilizer, especially in the top layer of the black soil root system, needs to be determined according to the nutrient requirements of the corresponding crop and the crop's tolerance to nutrient concentration.

[0149] After determining the base fertilizer concentration, it is necessary to determine the nutrient consumption of the crop in different growth stages. Based on the ratio of the two, the nutrient application amount can be obtained.

[0150] Specifically, for all the dispensing holes in the nutrient dispenser, it is necessary to determine the location of the dispensing hole, the root distribution at the depth of the dispensing hole, and analyze the nutrient requirements of the area to determine the dispensing amount for that area.

[0151] In particular, the amount of base fertilizer applied should be carefully controlled to avoid excessive application, which could lead to the formation of new black soil clumps in the soil layer.

[0152] The beneficial effect of step S140 is that after the black soil clumps have been pretreated and the treatment effect is guaranteed to meet the expected effect, base fertilizer is applied to the soil layer. It can also be guaranteed that the base fertilizer will not cause new black soil clumps to form. Therefore, in this case, sufficient nutrients can be provided.

[0153] As described in step S150, the purpose of this step is that the environment of the black soil root layer has a significant impact on the crop's growth status during the crop's growth period. Furthermore, the crop's performance can reflect the root system's condition. Therefore, real-time monitoring of the crop's condition is necessary during the crop's growth period, and real-time adjustments to the soil environment are made based on the monitoring results. Specifically:

[0154] S151. Monitor the crop status in real time during each crop growth cycle after planting.

[0155] The purpose of this step is to ensure that the crop condition is known at each growth stage during the crop's growth period, and that the normal performance of the crop at these growth stages is known over many years of agricultural practice. Therefore, it is necessary to determine whether there are any growth problems based on this monitoring of the crop condition.

[0156] After the crops are planted, their growth status is continuously monitored.

[0157] Each crop is monitored to determine if there are any growth defects in the monitored crop plants.

[0158] Specifically, the growth status of the crop needs to be recorded to determine the specific growth conditions.

[0159] S152. Compare the crop condition during the crop growth cycle with the theoretical condition to obtain crops with abnormal growth.

[0160] The purpose of this step is to monitor the growth status of the planted crops, determine whether the growth status is normal based on the monitoring results, and then judge the growth condition based on the results.

[0161] The process involves comparing the actual growth status of the crop in the current growth cycle with its theoretical status. If a significant difference is found between the two, the monitored crop is determined to be in an abnormal growth state.

[0162] The so-called theoretical state refers to the normal plant performance based on the recorded crop growth cycle, such as height, number of leaves, leaf color, and stem diameter.

[0163] S153. Based on the specific characteristics of crops with abnormal growth, obtain the nutrient requirements of crops with abnormal growth.

[0164] The purpose of this step is to determine the nutrient requirements of crops with abnormal growth compared to those with normal growth. In some cases, more nutrients may be needed for different types of abnormal growth, while in others, the amount of nutrients should be reduced. In order to save crops with abnormal growth, it is necessary to determine the nutrient requirements of the crops.

[0165] Once abnormal crops are identified, it is necessary to analyze the specific characteristics of these abnormal crops. These characteristics include all data used to evaluate crop growth, such as plant height, number of leaves, leaf color, and diameter of the main stem.

[0166] After identifying the specific characteristics of crops with abnormal growth, it is necessary to determine their nutrient requirements based on their specific characteristics and nutrient needs.

[0167] Among these, the key parameter for determining the required nutrients is the concentration of each type of nutrient applied.

[0168] S154. Based on the crop growth cycle, obtain the nutrient requirements of normally growing crops.

[0169] The purpose of this step is to consider not only crops with abnormal growth but also crops with normal growth in the environmental adjustment of the root zone of black soil, and to analyze the nutrient requirements of these crops in order to ensure that they can always maintain a normal growth state.

[0170] When determining that a crop is in a normal growth state, it is necessary to determine its current growth cycle.

[0171] When normal growth is observed, it is necessary to determine the nutrient requirements of the crop during its current growth cycle in order to provide continuous nutrient support.

[0172] When a normally growing crop is about to end its current growth cycle and enter the next growth cycle, it is necessary to determine the crop's nutrient requirements in advance during the initial period of the next growth cycle and adjust the nutrient requirements accordingly.

[0173] Among the nutrient requirements, the most crucial indicator is the concentration of various nutrients. Of course, other parameters such as the total amount of nutrients can also be set, but this is not a strict requirement. However, the concentration of various nutrients must be determined.

[0174] The beneficial effect of step S150 is that it is necessary to determine the growth status of the nutrient crop in each growth cycle and determine the nutrient requirements of the crop based on its status. Then, the nutrient requirement parameters of the crop growth cycle can be adjusted and supplied according to its requirements. Based on this, the environment can be adjusted, and the adjustment results can be more suitable for the growth status of the crop.

[0175] As described in step S160, the purpose of this step is that crop roots are often not evenly distributed. Applying more nutrients to areas with higher root density allows for more comprehensive nutrient absorption by the crop. Therefore, it is necessary to rationally allocate nutrients to promote crop growth through a more effective nutrient application method. Specifically:

[0176] S161. Obtain the root distribution density and location at different depths within the root layer of black soil.

[0177] The purpose of this step is to understand that the root distribution density varies at different depths within the root layer of black soil, and this is also related to the crop's growth cycle. In order to allocate nutrients according to the root distribution density, it is necessary to analyze the root status.

[0178] The method required for analyzing the root distribution pattern is to perform stratification based on the soil depth data. Of course, considering that the hole positions on the nutrient delivery device are usually fixed, the soil depth can also be set in the range of 1 to 3 cm below each hole. The reason for setting it below is that nutrients usually have a certain tendency to flow from the soil layer downwards.

[0179] After conducting in-depth analysis, testing equipment such as radar and ultrasound can be used to directly detect the root distribution density and location at various depths.

[0180] In some embodiments, the distribution density and location of the root system can be theoretically analyzed directly based on biological performance information from years of crop cultivation experience, and the results of the theoretical analysis can be used as actual data. Of course, this method has lower precision, but it can be used directly in large-scale cultivated land, especially when it is not possible to analyze each plant individually, in order to improve efficiency and reduce working costs.

[0181] Among them, the information of distribution density and distribution location can be matched, and the location with the highest root distribution density in each soil layer can be identified as the distribution location.

[0182] S162. Based on the root distribution and crop growth time, obtain the nutrient absorption rate of crop roots at different depths of the root layer in black soil.

[0183] The purpose of this step is to address the fact that, for crops grown on black soil, the rate of nutrient absorption varies at different growth stages, and this variation is often related to root volume. Furthermore, considering the need to avoid soil compaction and environmental imbalance caused by excessive nutrient application during crop growth, the core concept of this application is to quantitatively apply nutrients based on the crop's nutrient requirements to ensure that all nutrients are absorbed and do not accumulate. Therefore, it is necessary to determine the nutrient absorption rate of crop roots at different root depths in black soil. Specifically:

[0184] S1621. Based on the crop's growth time, obtain the theoretical root distribution and the theoretical nutrient absorption rate per unit volume of root system for crops with normal growth.

[0185] The purpose of this step is to determine the root density within the root layer of black soil and the nutrient absorption rate per unit root density in the analysis of nutrient absorption rate. Since both parameters are known, especially for crops with normal growth, they can be measured using various methods. Therefore, the desired results can be determined based on these measurable values ​​during the treatment.

[0186] Among them, obtaining the crop's growth time allows us to directly determine the current growth cycle of the crop based on this value. Furthermore, based on the recorded root system research parameters, we can directly determine the theoretical root distribution status of the crop in each root layer of black soil at the current period, as well as the theoretical nutrient absorption rate of the root system at each depth.

[0187] For the theoretical root distribution and theoretical nutrient absorption rate per unit volume of normally growing crops, the theoretical values ​​can be directly used as the actual values ​​without the need for actual measurement.

[0188] For theoretical values, they can be directly measured in the laboratory.

[0189] S1622. Based on the theoretical root distribution, obtain the root distribution volume within different depths of the root layer in black soil.

[0190] The purpose of this step is to obtain the total value once the unit value is determined, and then calculate the final result based on that value.

[0191] In this process, by obtaining the theoretical root distribution parameters, these theoretical values ​​can then be used as the actual root distribution parameters of the crop.

[0192] Among them, based on the current crop growth cycle, the root distribution volume values ​​within different black soil root layer depths can be directly obtained.

[0193] The theoretical root distribution can be obtained directly using laboratory testing methods.

[0194] S1623. Based on the root distribution volume and theoretical nutrient absorption rate per unit volume of root system within different black soil root layer depths, obtain the nutrient absorption rate of normally growing crops within different black soil root layer depths.

[0195] The purpose of this step is to determine the rate of nutrient absorption by the roots at different depths in the black soil root layer of normally growing crops, so that specific analysis can be carried out.

[0196] Considering that crop roots are usually radial, nutrient dispensers can be installed around a single plant to distribute nutrients evenly to the roots.

[0197] In the analysis of the root system per unit volume, the root distribution volume and the theoretical nutrient absorption rate of the root system per unit volume need to be multiplied to obtain the nutrient absorption rate of the root system within the root layer depth of the black soil.

[0198] If multiple nutrient dispensers are set up simultaneously in a uniform and surrounding manner to distribute nutrients, the volume range that each nutrient dispenser can cover needs to be determined, thereby determining the nutrient dispensing speed of each nutrient dispenser branch.

[0199] Among them, for the nutrient delivery speed of the nutrient dispenser, there is another known condition: the nutrient concentration. Within the range of this concentration, the upper limit is the range that will cause seedling burn, and the lower limit is the range of nutrients that the roots can absorb. The selection should be made within this range.

[0200] S1624. Obtain the measured root distribution of crops with abnormal growth, the nutrient absorption rate per unit volume of roots corresponding to the behavior of crops with abnormal growth, and obtain the nutrient absorption rate of crops with abnormal growth in different black soil root layers.

[0201] The purpose of this step is to identify another type of crop to be regulated: crops with abnormal growth. These crops often have unevenly distributed root systems, and their nutrient absorption rates are often different from those of crops with normal growth. Therefore, a separate analysis is needed for this type of crop.

[0202] For crops with abnormal growth, and considering that the number of such crops is very small, it is possible to conduct on-site measurements of the root system of these crops. Therefore, in the specific analysis, on-site measurements of the root system of these crops with abnormal growth should be carried out. These measurements can be processed using radar and ultrasonic equipment.

[0203] In this approach, considering that the root systems of crops with abnormal growth are often unevenly distributed, it is necessary to determine the location of areas with high root density. In other words, these areas are where nutrients need to be applied. The core idea of ​​this approach is to make full use of the root systems in areas with higher root density, while areas with low root density can be discarded.

[0204] For crops exhibiting abnormal growth, the nutrient absorption rate per unit area of ​​the root system can be determined based on preliminary laboratory experiments. This yields the nutrient absorption rate per unit volume of the root system corresponding to the abnormal growth of the crop.

[0205] One way to obtain the nutrient absorption rate of abnormal-growing crops at different depths of the black soil root system is to directly multiply the nutrient absorption rate per unit volume of the root system corresponding to the abnormal growth of the crop by the root distribution volume of the abnormal-growing crop.

[0206] S163. Adjust the nutrient delivery flow rate of the nutrient delivery device at different black soil root layer depths according to the nutrient absorption rate at different black soil root layer depths, and then deliver the nutrients.

[0207] The purpose of this step is to deliver nutrients to the root zone of the black soil according to the obtained analytical values.

[0208] Among them, the nutrient absorption rate at different root depths in black soil needs to be determined based on this value to determine the net nutrient content that needs to be provided to the soil per unit time.

[0209] Once the net nutrient content to be supplied to the soil per unit time is obtained, and the nutrient concentration is determined, the ratio of net nutrient content to concentration can be calculated to determine the nutrient delivery rate per unit time.

[0210] After obtaining the nutrient delivery flow rate, it is necessary to maintain the nutrient delivery flow rate within that unit of time, and continuously deliver nutrients according to the flow rate value of the delivery holes of the nutrient delivery device corresponding to different root depths in black soil.

[0211] The beneficial effect of step S160 is that by analyzing the root distribution and nutrient absorption rate within the obtained black soil root layer depth, the nutrient absorption rate within different root layer depths can be determined. Then, by using this nutrient absorption rate, nutrients can be applied, ensuring that the nutrients applied within different black soil root layer depths can be used immediately. This avoids the accumulation of nutrients that cannot be absorbed in time within the black soil root layer, which could lead to clumping or soil acidification.

[0212] As described in step S170, the purpose of this step is to address the issue that, in some cases, caking can occur within the root layer of black soil during crop growth. Therefore, specific treatments should be designed to avoid this situation and prevent caking from negatively impacting crop growth. Specifically:

[0213] S171. Regularly monitor the black soil root layer compaction status during crop growth and obtain black soil compaction that affects crop growth.

[0214] The purpose of this step is to determine whether there is clumping in the root layer of the black soil, and thus whether further work is needed.

[0215] Considering the randomness, location-specificity, and other types of randomness in the occurrence of black soil clumping during crop growth, it is necessary to measure the entire land area in the specific treatment.

[0216] Among these methods, the measurement of black soil clumping can be carried out by dividing the land into plots and regions to detect the formation of black soil clumping within the root layer.

[0217] Among these, it is necessary to regularly monitor the clotting status of the black soil root layer. The monitoring process can be carried out using equipment and foundations such as radar and ultrasonic detection. The analysis process of black soil clotting parameters can be carried out according to the scheme in step S110.

[0218] Among them, black soil clumping that affects crop growth, including situations where the pH of the black soil clumping significantly causes problems in crop growth or significantly affects root distribution, can all be considered as affecting crop growth.

[0219] S172. Based on the causes and structure of black soil clotting that affects crop growth, a new black soil clotting improver is formulated.

[0220] The purpose of this step is to determine that black soil clumps do not necessarily affect crop growth. For black soil clumps that do not affect crop growth, no additional treatment is needed to save resources. In this case, it is necessary to determine the specific condition of the black soil clumps.

[0221] When it is found that black soil clumps can affect crops, the black soil clumps need to be treated. This can be done based on the black soil clump treatment method mentioned above. The basic work is to prepare a black soil clump improver. This method is the same as step S120 and will not be repeated here.

[0222] S173. The new black soil agglomeration improver is applied, and the nutrient application data is adjusted until the volume of black soil agglomerates that affect crop growth decreases to a level that does not affect crop growth.

[0223] The purpose of this step is to apply a black soil clogging improver and adjust the nutrient application parameters to ensure that the soil environment in the root zone meets the normal growth needs of crops and does not lead to the formation of black soil clogging.

[0224] The method for applying the black soil agglomeration improver is the same as that in step S130, and will not be repeated here.

[0225] The method for adjusting the nutrient application data is the same as that in steps S150-S160, and will not be repeated here.

[0226] The beneficial effect of step S170 is that by analyzing the state of black soil clumps in the root zone of the crop during the crop growth period, and analyzing whether the black soil clumps need to be treated based on the actual situation, the black soil clumps can be treated according to the actual situation, and the nutrient application data can be adjusted based on this as a standard to ensure the dissolution of black soil clumps during the crop growth period and to avoid the formation of new black soil clumps.

[0227] The beneficial effects of this application include:

[0228] 1. Personalized environmental adjustment is achieved. In the technical solution of this application, the black soil clumps in the root layer of black soil are monitored. Based on the monitoring results, the parameters for the application of the amendment for the black soil clumps are determined, thereby achieving personalized improvement. At the same time, the root layer clump information is also analyzed during the crop cultivation process. Based on the analysis results, further environmental adjustments can be made based on the monitoring results, thereby achieving personalized environmental adjustment throughout the entire process.

[0229] 2. Highly efficient environmental adjustment is achieved. In the technical solution of this application, the adjustment of black soil clumps within the black soil root layer and the nutrient supply process for crops are carried out by directly applying soil conditioners or nutrients to the black soil clumps and crop roots, thereby directly adjusting the environment of the black soil root layer and improving the efficiency of environmental adjustment. In addition, during the nutrient environment adjustment, the nutrient supply and whether and how much soil conditioner is applied are adjusted in real time according to the root distribution of the crops, thus fully improving the efficiency of environmental adjustment of the black soil root layer.

[0230] 3. Environmental adjustment throughout the entire process is achieved. In the technical solution of this application, the soil compaction state and fertility state are analyzed before crop planting to pre-adjust the soil environment before crop planting. At the same time, during the crop growth period, soil compaction and fertility parameters, as well as crop growth status, are continuously tracked and analyzed. Based on the tracking and monitoring results, nutrients and black soil compaction improvers are added to the soil, thereby ensuring that environmental adjustment is carried out continuously from before planting to the entire growth period of the crop, thus achieving environmental adjustment of the black soil root layer soil throughout the entire crop planting process.
