Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural technology, and in particular to a method and system for predicting soil nutrients based on radioactive elements. Background Technology

[0002] Currently, existing soil nutrient testing methods mainly rely on laboratory chemical testing. This involves collecting fresh soil samples and preparing them through a process of air drying, grinding, sieving, and packaging. The collected samples are then sent to the laboratory where soil nutrients are measured using chemical reagents. Examples of methods include using sodium bicarbonate solution for shaking extraction to measure available phosphorus, ammonium acetate solution for centrifugation extraction to measure available potassium, and potassium dichromate oxidation-external heating method to measure organic matter.

[0003] A single sample full-item test requires ≥72 hours (including sample preparation and analysis), the cost of a single sample test is ¥300-500 (including manpower and consumables), the equipment investment is ¥1 million+ (for a complete laboratory setup) and requires professional laboratory technicians to operate precision instruments.

[0004] In practical applications, existing technologies have the following problems and shortcomings:

[0005] Commonly used soil testing methods include atomic absorption spectrometry (AAS), atomic fluorescence spectrometry (AFS), X-ray fluorescence spectrometry (XRF), ion chromatography (IC), electrochemical analysis methods, chemical methods, and laser-induced breakdown spectroscopy (LIBS). All of these methods require pretreatment of the soil, such as drying, grinding, and sieving, resulting in poor timeliness, high testing costs, and difficulty in achieving rapid testing of soil properties in the deep underground layers of large-scale farmland.

[0006] With the continuous deepening and development of soil quality research, radioactive nuclides in the soil can effectively reflect changes in soil fertility and structure through the release of gamma rays in the quantitative evaluation of soil erosion intensity. These radioactive nuclides are relatively stably and uniformly distributed on the soil surface through atmospheric deposition, and their slow radioactive decay causes physical and mechanical transport of soil particles. Therefore, radioactive nuclides can, to a certain extent, characterize the degree of soil erosion and quality degradation.

[0007] In summary, the aforementioned defects in the existing technology are due to the high cost and slow speed of laboratory testing, and the fact that soil samples are prone to deterioration during transport to the laboratory, affecting the test results. Through analysis and research on soil radioactive elements and nutrient elements obtained from testing, the inventors discovered that this defect can be solved by establishing and training an artificial intelligence model. That is, without sending samples to the laboratory for testing, the information on soil radioactive elements measured on-site can be directly converted into soil nutrient content information through a computer model program.

[0008] Therefore, using soil radioactive element information for rapid soil nutrient detection is of great practical significance. There is an urgent need to research a novel method and system for predicting soil nutrients based on radioactive elements. Summary of the Invention

[0018] The gradient descent algorithm is used for model training, and the gradient of the loss function of the prediction model with respect to different parameters is calculated.

[0062] The following are system embodiments corresponding to the above method embodiments. This embodiment can be implemented in conjunction with the above embodiments. The relevant technical details mentioned in the above embodiments are still valid in this embodiment, and will not be repeated here to reduce repetition. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the above embodiments.

[0063] This invention aims to propose a method for predicting soil nutrients based on radioactive elements. The invention constructs and trains a deep learning model based on a multi-layer neural network. The input is the content of 18 radioactive elements (uranium, thorium, potassium, etc.) in the soil, and the output is the model's predicted content of 9 nutrient elements (nitrogen, phosphorus, potassium, etc.) in the soil. The accuracy of the nutrient content predicted by the model compared to laboratory measurements can reach 80%-90%.

[0064] This invention designs and develops a multi-agent collaborative system based on a large model. The system mainly includes a data query agent, a model calling agent, and a text retrieval agent. The agents call each other sequentially and cooperate with each other. It can analyze soil conditions using a soil nutrient prediction model and provide reasonable land management solutions with the help of a soil knowledge base.

[0065] The system of this application embodiment will be described in detail below with reference to specific embodiments:

[0066] Example 1

[0067] like Figure 1 As shown in the embodiments of this application, a soil nutrient prediction system based on radioactive elements is proposed. This soil nutrient prediction system is a multi-agent collaborative system based on large model decision-making. The system mainly includes a soil nutrient prediction model construction module 101, a soil data query agent module 102, a soil nutrient prediction agent module 103, and a soil remediation decision-making agent module 104. The calling process between agents is as follows: Figure 2 As shown:

[0068] Soil nutrient prediction model construction module 101: Based on different soil types, it is used to construct and train various soil nutrient prediction models based on multi-layer neural networks. The soil nutrient prediction model is used to predict the content of various nutrient elements in the soil based on the content of various radioactive elements in the input soil.

[0069] Soil data query intelligent agent module 102: It is used to input the query statement containing soil radioactive elements into the large language model, access the database according to the generated database statement, and return the query results;

[0070] Soil nutrient prediction intelligent agent module 103: It is used to read the query results of the database, select a suitable soil nutrient prediction model through the large model, call the soil nutrient prediction model, and realize the prediction and output of soil nutrient content information based on soil radioactive element information, and integrate and output a land health check report.

[0071] In this embodiment of the invention, the above-mentioned soil nutrient prediction system based on radioactive elements further includes:

[0072] Soil remediation decision-making intelligent agent module 104: Based on the input land health check report, it accesses the land knowledge base and uses a large model to match the most relevant remediation documents to the input land conditions, retrieves relevant information, and generates a land remediation decision-making scheme through the large model.

[0073] In this embodiment of the invention, the soil nutrient prediction model construction module 101 performs the following steps:

[0074] A loss function is defined to measure the deviation between the model's predicted values ​​and the actual values, so that the deviation between the predicted values ​​and the actual values ​​of the soil nutrient prediction model on the training data is minimized, and the optimal parameters for model training are obtained.

[0075] The gradient descent algorithm is used for model training, and the gradient of the loss function of the prediction model with respect to different parameters is calculated.

[0076] During training, forward propagation is used to calculate and retain the relevant intermediate values ​​of each layer, and backpropagation uses the chain rule to calculate the gradient of the loss function with respect to the parameters of each layer. Regularization and other methods are used to prevent overfitting of the parameters.

[0077] Specifically, in a specific embodiment of the present invention, the training of the above-mentioned prediction model includes:

[0078] 1) Neural network model structure

[0079] like Figure 3 As shown, an Artificial Neural Network (ANN) is a mathematical or computational model that mimics the information processing of a biological nervous system. It consists of a large number of nodes (or neurons) and the connections between them. Each node represents a simple processing unit capable of receiving input signals, processing them, and outputting a signal. The strength of the connections between these nodes, i.e., the weights, can be adjusted through a learning process, enabling the network to perform specific tasks such as classification, regression, and clustering.

[0080] The current problem type is a typical multiple regression problem, and it is trained using a multilayer fully connected neural network model and related algorithms as shown in the figure below.

[0081] 2) Neural Network Model Training Methods

[0082] Model training involves finding suitable parameters that minimize the deviation between the model's predicted values ​​and the actual values ​​on the training data. First, a loss function is defined to measure the deviation between the model's predicted values ​​and the actual values. The loss function used in this model training is the mean squared error (MSE).

[0083] The model training uses the gradient descent algorithm to calculate the gradient of the model's loss function with respect to different parameters (the gradient is the direction in which the function changes the fastest, and it can be obtained by differentiation).

[0084] like Figure 4 and Figure 5 As shown, in actual training, the neural network model is trained using gradient descent by combining forward propagation (calculating and retaining the relevant intermediate values ​​of each layer) and backpropagation (using the chain rule to calculate the gradient of the loss function with respect to the parameters of each layer). Simultaneously, dropout and regularization are used during training to prevent overfitting.

[0085] 3) Model Performance Evaluation

[0086] Cross-validation of the deep learning model was performed using a small dataset of 350 sets of data (k=7, i.e., 300 sets of training data and 50 sets of test data). The evaluation results are as follows: Figures 6a-6c As shown.

[0087] In this embodiment of the invention, the soil data query intelligent agent module 102 performs the following steps:

[0088] The input natural language query statement is transformed into a database query statement through a large language model;

[0089] Based on the information in the database query statement, access the database and return the query results;

[0090] The query results are output and stored in the form of a database file.

[0091] Specifically, in a specific embodiment of the present invention, the soil data query intelligent agent module 102 has the ability to connect to and query the database and perform data query and processing. It can convert the input natural language query into an SQL database query statement through a large model, and then call relevant tools according to the database information to access the database and return the query results. At the same time, it can choose to output and store the query results in the form of a file.

[0092] like Figure 7 As shown, suppose the example database stores information on time, farm, plot, temperature, type, and soil radioactivity measured by gamma spectroscopy. The figure below illustrates how a data query agent can directly query and return all information for plots 10 to 20 of the Northeast Demonstration Farm from June 25th to 27th.

[0093] In this embodiment of the invention, the soil nutrient prediction intelligent agent module 103 performs the following steps:

[0094] Based on the query results, the land data is parsed and matched with the corresponding soil nutrient prediction model to predict soil nutrients.

[0095] The soil nutrient prediction model performs inference to obtain nutrient prediction data for the land;

[0096] The soil nutrient prediction data and location information data are integrated to output a land health check report.

[0097] Specifically, in this embodiment of the invention, the soil nutrient prediction agent module 103 has the ability to access file directories and perform file analysis, call model code, and integrate information. When working, the agent first reads the soil data file that needs to be parsed, then calls tools to access all types of soil nutrient prediction models in the model directory and selects a suitable soil model from the large model list. It then calls the model to convert the radioactive element information in the data into soil nutrient content information, and finally integrates all the data into complete information about the land plot.

[0098] like Figure 8 As shown, taking the output of the aforementioned data query agent as an example, assuming the model library contains multiple pre-trained soil nutrient prediction models, the agent will first parse the land data and match the Northeast saline-alkali land model as the most suitable model for soil nutrient prediction. Then, it will call the tool to execute the model code for inference, obtaining the land nutrient prediction data. Finally, it will integrate the soil nutrient data with other location information and output the final land health check report. The following figure illustrates the agent's workflow and results.

[0099] In this embodiment of the invention, the soil remediation decision-making intelligent agent module 104 performs the following steps:

[0100] Analyze the input land health check report, access all documents in the land knowledge base, and use a large model to match the governance documents related to the input land situation;

[0101] Retrieve relevant information from governance documents and generate governance decision-making schemes for land types using a large language model.

[0102] Specifically, in a specific embodiment of the present invention, the soil remediation decision-making intelligent agent module 104 has the function of accessing the file directory and performing file analysis, retrieving information related to the input question in the knowledge base and generating answers using a large model, i.e., general retrieval augmented generation (RAG) capability, which will not be elaborated here.

[0103] like Figure 9 As shown, taking the land health check report output by the soil nutrient prediction agent module 103 as an example, assuming the knowledge base already contains multiple documents related to soil remediation, the agent will first analyze the input land health check report, then call tools to access all documents in the land knowledge base, and use a large model to match the remediation documents most relevant to the input land situation, retrieve relevant information from them, and finally output a remediation decision plan for the land through a large model generation method. The following figure illustrates the working process and results of this agent.

[0104] Specifically, in this embodiment of the invention, the Python version required for the soil nutrient prediction system based on radioactive elements to run is 3.11, and the corresponding Python packages and versions are as follows:

[0105] torch == 2.7.0

[0106] torchvision == 0.21.0
