Description

Technical Field

[0001] This invention belongs to the field of soil testing and analysis, and more specifically, relates to a method and system for improving soil in medicinal herb planting areas. Background Technology

[0002] Chinese medicinal herbs are mostly cultivated in rural areas and remote mountainous regions. There are more than 12,000 kinds of Chinese medicinal herbs, with about 300 commonly used. Among them, 115 kinds of medicinal herbs are both food and medicine.

[0003] The essence of Chinese medicinal herbs is natural plants, animals, and minerals. The accumulation of their effective components is greatly influenced by the local environment. Among them, the soil environment of the planting site directly affects the yield and quality of Chinese medicinal herbs. However, the excessive use of chemical fertilizers in the cultivation of Chinese medicinal herbs, leading to soil acidification and compaction, depletion of organic matter and trace elements, and changes in the microbial biodiversity ecology are important reasons. The problem of continuous cropping obstacles in the authentic producing areas and the substandard quality in non-authentic producing areas not only leads to unstable yields of Chinese medicinal herbs, but also results in the instability of the planting sites, making it difficult to guarantee the quality from the source.

[0004] Currently, relevant studies have proposed methods for improving the soil in medicinal herb planting areas. For example, patent application publication number CN115176550A proposes a method for improving the soil for medicinal herb planting using microbial fertilizers. This method involves sampling the soil in sections and randomly sampling points to measure various fertilizer indicators in the soil of medicinal herb planting fields. Based on the nutritional requirements of medicinal herb planting, the required content of microbial fertilizers in the soil is determined, allowing for targeted preparation and application of microbial fertilizers. This method improves the soil before medicinal herb cultivation by increasing the supply of nutrients through microorganisms, promoting the absorption and utilization of nutrients by medicinal herbs, reducing pests and diseases and increasing the yield of medicinal herbs, reducing the content of heavy metals in the soil, improving the soil acidity environment, improving soil compaction, and enhancing soil utilization. However, this method improves the planting site based on the growth requirements of the medicinal herb varieties, completely ignoring the specificity of the medicinal herb's authentic attributes. The growth of Chinese medicinal herbs is a complex process involving the interaction of multiple factors. Directly mapping the growth requirements of medicinal herb varieties to relevant fertility indicators cannot effectively improve the growth quality of Chinese medicinal herbs. Summary of the Invention

[0005] To address the shortcomings and improvement needs of existing technologies, this invention provides a method and system for improving the soil in medicinal herb cultivation areas. The purpose is to fully utilize prior knowledge of the authentic producing areas of medicinal herbs, and by studying the differences between the soil in authentic and non-authentic producing areas of the same medicinal herb, determine the specific parameters for improving the soil in non-authentic producing areas and remediating the soil in authentic producing areas, thereby fundamentally improving the growth quality of medicinal herbs.

[0006] To achieve the above objectives, according to one aspect of the present invention, a method for improving the soil of medicinal herb cultivation sites is provided, comprising: S1: Obtain soil testing data and medicinal herb testing data from multiple sampling points located in both the original and non-original producing areas of the target medicinal herb; the medicinal herb testing data includes the content of effective components of the target medicinal herb; the soil testing data includes the physicochemical indicators, nutrient content, and trace element content of the soil.

[0007] S2: Select sampling points where the effective component content of the target Chinese medicinal materials is not lower than the preset threshold, and statistically analyze the range of physicochemical indicators, nutrient content range and trace element content range of the soil at these sampling points. Use the lower limit values ​​of the physicochemical indicator range, the nutrient content range and the trace element content range as the standard formula. S3: Obtain soil testing data of the target medicinal material's planting site and compare it with the standard formula. Based on the comparison analysis results, determine the adjustment parameters for adjusting the soil physicochemical indicators and components of the target medicinal material's planting site. After adjusting the soil of the target medicinal material's planting site according to the adjustment parameters, all physicochemical indicators are within the corresponding range, the content of each nutrient is not lower than the corresponding lower limit of the nutrient range, and the content of each trace element is not lower than the corresponding lower limit of the trace element range, thereby achieving soil improvement of the target medicinal material's planting site.

[0008] Furthermore, in S2, before using the range of physicochemical indicators, nutrient content, and trace element content of the soil at the selected sampling points as the standard formula, it also includes: retaining only the sampling points with the highest content of effective components of the target Chinese medicinal materials and eliminating the rest of the sampling points.

The soil testing data includes the soil's physicochemical indicators, nutrient content, and trace element content; the medicinal herb testing data includes the content of the target medicinal herb's effective components. The analysis module is used to screen out sampling points where the effective component content of the target Chinese medicinal materials is not lower than the preset threshold, and to statistically analyze the range of physicochemical indicators, nutrient content range and trace element content range of the soil at these sampling points. The lower limit values ​​of the physicochemical indicator range, the nutrient content range and the trace element content range are used as the standard formula. The sampling module is also used to obtain soil testing data from the planting site of the target medicinal material; The analysis module is also used to compare and analyze the soil data of the target medicinal herb planting site with the standard formula. Based on the comparison and analysis results, the adjustment parameters for adjusting the soil physicochemical indicators and components of the target medicinal herb planting site are determined. After adjusting the soil of the target medicinal herb planting site according to the adjustment parameters, each physicochemical indicator is within the corresponding range, the content of each nutrient is not lower than the lower limit of the corresponding nutrient range, and the content of each trace element is not lower than the lower limit of the corresponding trace element content range, thereby achieving soil improvement of the target medicinal herb planting site.

[0013] Furthermore, the soil improvement system for medicinal herb planting sites based on digital twins provided by the present invention also includes: a GIS data management module; The GIS data management module is used to delineate each sampling point and each planting area, and extract the attribute parameters of each delineated plot; the attribute parameters include: plot area and coordinates.

[0016] Furthermore, the storage module is a MySQL database, and the visualization module is the SQLyog graphical management tool.

[0017] In summary, the above-described technical solutions conceived in this invention can achieve the following beneficial effects: (1) The traditional producing area is a specific producing area of ​​the best quality medicinal materials. This invention determines the standard formula for medicinal material planting based on soil test data and the test results of effective components of medicinal materials from multiple sampling points in the traditional producing area. Based on the difference between the soil test results of the medicinal material planting area and the standard formula, it determines the adjustment parameters for soil improvement in the planting area. Based on the growth mechanism and law of medicinal materials in the traditional producing area, it can provide a scientific and effective basis for soil improvement in both traditional and non-traditional producing areas. It can effectively increase the content of effective components in medicinal materials in the planting area, realize scientific fertilization and soil management, and provide reliable technical support for solving the problems of overuse of farmyard manure, soil acidification and continuous cropping obstacles that are currently common in medicinal material planting.

[0018] (2) When determining the standard formula for soil improvement, the present invention selects pH value as the physicochemical index, organic matter, hydrolyzable nitrogen, available phosphorus, slow-release potassium and readily available potassium as the nutrient components, and available sulfur, available copper, available zinc, available iron, available manganese and available boron as the trace elements. The corresponding indexes are the most critical indicators in the soil for affecting the content of effective components in Chinese medicinal materials, thereby achieving effective improvement of the soil in the planting area.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0025] In this invention, the terms "first," "second," etc. (if present) in the invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The ten traditional Chinese medicinal herbs of Hubei Province include: Artemisia argyi, Pinellia ternata, Gastrodia elata, Coptis chinensis, Poria cocos, Chrysanthemum morifolium, Atractylodes lancea, tortoise shell and turtle shell, Ginkgo biloba, Magnolia officinalis, and Polygonatum sibiricum (tied for tenth place). Among them, Atractylodes lancea is a rhizome-type medicinal herb, which faces challenges due to continuous cropping. Its authentic producing area is Yingshan County, with a planting area of ​​20,000 mu. Baokang County and Chibi area are not its authentic producing areas. Yingshan County is located in Huanggang City, in eastern Hubei; Baokang County is located in Xiangyang City, in northwestern Hubei; and Chibi City is located in Xianning City, in southern Hubei. These three areas are distributed in three different parts of Hubei and have excellent research value.

[0027] Without loss of generality, Atractylodes lancea is used as the target Chinese medicinal material in the following examples for explanation and description.

[0028] The following is an example.

[0029] Example 1: A method for improving the soil in planting areas of Chinese medicinal herbs, such as Figure 1 As shown, it includes: S1: Obtain soil testing data and medicinal herb testing data from multiple sampling points located in the target medicinal herb's authentic producing area; the medicinal herb testing data includes the content of effective components of the target medicinal herb; the soil testing data includes the soil's physicochemical indicators, nutrient content, and trace element content.

[0030] S2: Select sampling points where the effective component content of the target Chinese medicinal materials is not lower than the preset threshold, and statistically analyze the range of physicochemical indicators, nutrient content range and trace element content range of the soil at these sampling points. Use the lower limit values ​​of the physicochemical indicator range, the nutrient content range and the trace element content range as the standard formula. S3: Obtain soil testing data of the target medicinal material's planting site and compare it with the standard formula. Based on the comparison analysis results, determine the adjustment parameters for adjusting the soil physicochemical indicators and components of the target medicinal material's planting site. After adjusting the soil of the target medicinal material's planting site according to the adjustment parameters, all physicochemical indicators are within the corresponding range, the content of each nutrient is not lower than the corresponding lower limit of the nutrient range, and the content of each trace element is not lower than the corresponding lower limit of the trace element range, thereby achieving soil improvement of the target medicinal material's planting site.

[0031] Based on the growth characteristics of Chinese medicinal herbs, this embodiment selects the soil physicochemical indicators, nutrient content, and trace element content of the authentic producing areas as references. Based on the soil differences between the planting area and the authentic producing areas, it guides the soil improvement of the planting area. The relevant improvement methods are consistent with the planting mechanism and growth pattern of Chinese medicinal herbs, which can effectively improve the growth environment of Chinese medicinal herbs and improve the growth quality of Chinese medicinal herbs in the planting area.

[0032] The following provides a more detailed explanation of this embodiment.

[0033] In this embodiment, the target medicinal herb is Atractylodes lancea, whose authentic producing area is Yingshan County, Hubei Province. To fully verify the effectiveness of this embodiment, multiple sampling points were also set up in Baokang and Chibi, non-authentic producing areas. The study investigated the impact of the effective component content, trace component content, and microbial diversity of the soil in Yingshan (authentic producing area), Baokang (non-authentic producing area), and Chibi (non-authentic producing area) on the effective components and yield of the medicinal herb. The study also attempted to use digital technology to achieve scientific cultivation. Specifically, five samples were collected from each of the three regions. Key physicochemical indicators such as soil pH, key nutrient indicators such as organic matter, hydrolyzable nitrogen, available phosphorus, slow-release potassium, and readily available potassium, and key trace element indicators such as available sulfur, available iron, available manganese, available copper, available zinc, and available boron were tested. Based on this, a standard soil formula table for authentic Atractylodes lancea cultivation was generated to facilitate scientific fertilization and soil management.

[0034] Optionally, in this embodiment, multiple sampling points in the Atractylodes lancea producing area and the current planting sites are located using the BIGEMAP Pro version GIS system, and their key parameters such as coordinates and area are statistically analyzed and uniformly labeled. YS01~YS05 represent five sampling points in Yingshan City, BK01~BK05 represent plots in five planting areas in Baokang City, and CB01~CB05 represent plots in five planting areas in Chibi City.

[0035] The coordinates of the sampling points for each of the BK01 to BK05 ​​plots were recorded during sampling. The latitude, longitude, and area of ​​each plot are shown in Table 1.

[0036]

[0037] Taking area BK05 ​​in Baokang as an example, the process of constructing sampling point coding and positioning using the BIGEMAP Pro system specifically includes: Enter the coordinates of sampling point BK05 ​​in the BIGEMAP Pro system: 110.905780 0 E, 31.695751 0 N. By accessing the satellite map through the GIS system, the entire planting area can be viewed. The planting area can be circled and coded in the software, and its area parameters can be displayed. The results are as follows: Figure 2As shown, the area information is recorded in Table 1. The same method is used to process sampling points BK01, BK02, BK03, and BK04.

[0038] This embodiment enables digital traceability from the source by locating each planting plot.

[0039] After delineating the various plots, the effective components of the medicinal herbs, soil physicochemical indicators, nutrient content, and trace element content were tested at each sampling point in the authentic producing area and at each plot in the planting area. The results are as follows: According to the determination in Part I of the 2020 Pharmacopoeia (General Chapter 0512, Method II), calculated on a dried basis, it contains atractylodesin (C... 13 H 10 The content of atractylodes (O) must not be less than 0.3%. The test results from sampling points in Yingshan, Baokang, and Chibi are shown in Tables 2, 3, and 4, respectively. The results show that the atractylodes content at the five sampling points in Chibi ranged from 0.07% to 0.09%, and the content at the five sampling points in Baokang ranged from 0.06% to 0.23%. The content in both areas was substandard and did not meet the standards for traditional Chinese medicine decoction pieces. In contrast, the content at the five sampling points in Yingshan ranged from 0.32% to 0.91%, all exceeding the requirements of the pharmacopoeia. The content of YSO1 was 0.71%, and the highest content of YSO2 was 0.91%. As a preferred implementation method, this embodiment uses YSO2 as a reference for the optimal planting soil conditions in the authentic producing area; the content of YSO2 and other sampling points in Yingshan are used as references for trend analysis.

[0040]

[0041]

[0042]

[0043] pH values: In Yingshan, the authentic producing area, the pH value was 6.5-6.9, which is generally suitable and conducive to the growth of medicinal herbs, as shown in Table 2. In Baokang, the pH value was 5.5-6.9, with soil acidification in BK03 and BK05, reaching as high as 40% in the five sampling points, as shown in Table 3. In Chibi, the pH value was 4.6-4.9; the pH value was severely low, as shown in Table 4. The soil acidification in Chibi City, Xianning is severe and clearly unsuitable for the cultivation of this type of medicinal herb.

[0044] The organic matter content at the Chibi sampling point ranged from 6.28 to 19.5 g / kg. Except for CB01, the organic matter content at other sampling points was below 1.0%, and overall it was significantly lower than that at sampling points in Baokang and Yingshan, indicating that the soil in Chibi is not only severely acidified but also relatively infertile. The organic matter content at the Baokang sampling point ranged from 12.1 to 27.9 g / kg. The organic matter content at the Yingshan sampling point, a traditional producing area, ranged from 21.6 to 42.9 g / kg, and was generally higher than that in other non-traditional producing areas.

[0045] The effective zinc content at the YS02 sampling point was significantly higher than that at the Baokang sampling point. Zinc plays a crucial role in crop growth; it not only activates enzyme activity but is also an important element in promoting photosynthesis and regulating plant hormone synthesis. Plants absorb zinc from the soil through their roots and transport it to various tissues using transport proteins in root cells. Within plants, zinc exists primarily in ionic form, binding with proteins to form zinc proteins, which then participate in various biochemical reactions. Zinc plays a key role in photosynthesis, participating not only in the synthesis of photosynthetic pigments but also influencing the photosynthetic electron transport chain and carbon fixation processes. Furthermore, zinc promotes plant metabolic activities such as protein synthesis, carbohydrate metabolism, and nucleic acid synthesis. Therefore, the impact of zinc on the content of effective components in medicinal materials needs to be closely monitored.

[0046] To ensure a higher content of atractylodes lancea, the active ingredient in the planted Atractylodes lancea, after improvement, this embodiment selects the soil physicochemical indicators, nutrient content, and trace element content of sampling point YS02, which has the highest atractylodes lancea content in the authentic producing area, as the standard formula. It should be noted that the standard formula can be appropriately broadened based on the actual planting needs of the planting area. Specifically, sampling points with high (above a certain threshold) content of the active ingredient in the medicinal materials are selected from the authentic producing area. Based on the soil test results of these sampling points, the ranges of various physicochemical indicators, nutrient content, and trace element content are determined. The lower limits of these ranges are then used as the standard formula.

[0047] In this embodiment, the standard formula based on YSO2 is shown in Table 5.

[0048]

[0049] Based on the differences between the various indicators of the planting site and the standard formula, adjustment parameters for physicochemical indicators, various nutrients, and trace elements can be determined. These adjustment parameters indicate how much the corresponding physicochemical indicators need to be increased or decreased, how much of the corresponding nutrient content needs to be supplemented, and how much of the corresponding trace element content needs to be supplemented. It should be noted that, considering the continuous cropping obstacles during the growth of medicinal herbs, when determining the adjustment parameters for various nutrients and trace elements in the planting site, it is sufficient to ensure that each nutrient is not lower than the lower limit of its corresponding range. Therefore, no adjustment is needed for nutrients and trace elements in the planting site that are not lower than the corresponding lower limit. Based on these adjustment parameters, fertilizers containing the corresponding components can be selected and formulated into regulators, which can then be applied to the planting site to achieve soil improvement. When customizing regulators, the area of ​​the plot, soil density, and the content of the relevant components in the fertilizer need to be considered.

[0050] Generally, the density of sandy soil is about 1.5 T / m³. 3 It's easy to understand that this value is not absolute, as soil density is affected by various factors such as its composition, moisture content, and degree of compaction. In practical applications, it should be determined according to the actual soil conditions. In this embodiment, the soil density is approximately 1.5 T / m³. 3 The dry weight of soil in the 0-20cm depth is approximately 300kg.

[0051] The following example demonstrates the formulation of a customized soil conditioner based on organic matter and available zinc. Raw material A was selected to supplement organic matter, and raw material B was selected to supplement available zinc. Raw material A contains 916 g / kg of organic matter; raw material B contains 3.45 × 10⁻⁶ g / kg of available zinc. 5 mg / kg.

[0052] Taking the development of customized soil conditioner BK05 ​​with organic matter and available zinc as an example, the ingredients are as follows: The area is 532.0 m², the original soil organic matter content is 27.9 g / kg, and the standard formula is 30 g / kg. The required weight of raw material A for the plot is (30 - 27.9) × 300 × 532 / 916 = 366 kg; the original soil available zinc content of BK05 ​​is 0.72 mg / kg; the standard formula exchangeable zinc content is 5.8 mg / kg; the required weight of raw material B for the plot is (5.8 - 0.72) × 300 × 532.0 / 3.45 × 10⁵ = 2.35 kg.

[0053] Overall, this embodiment determines relevant parameters for soil improvement in medicinal herb planting areas based on the differences in soil physicochemical indicators, nutrient content, and trace element content between medicinal herb planting areas and their authentic producing areas. It provides a scientific and effective basis for soil improvement in planting areas based on the growth mechanisms and patterns of medicinal herbs in their authentic producing areas. This can effectively increase the content of effective components in medicinal herbs in planting areas, achieve scientific fertilization and soil management, and provide reliable technical support for solving the current problems of overuse of farmyard manure, soil acidification, and continuous cropping obstacles in medicinal herb cultivation.

[0054] It should be noted that this embodiment is applicable not only to Atractylodes lancea, but also to all medicinal materials included in the National Pharmacopoeia, such as ginseng, astragalus, Panax notoginseng, Coptis chinensis, Codonopsis pilosula, Artemisia argyi, licorice, honeysuckle, Pinellia ternata, Polygonatum sibiricum, and Pseudostellaria heterophylla.

[0055] Example 2: A soil improvement system for medicinal herb planting sites based on digital twins includes: a sampling module and an analysis module; The sampling module is used to acquire soil testing data and medicinal herb testing data from multiple sampling points located in the target medicinal herb's authentic producing area. The soil testing data includes the soil's physicochemical indicators, nutrient content, and trace element content; the medicinal herb testing data includes the content of the target medicinal herb's effective components. The analysis module is used to screen out sampling points where the content of effective components of the target Chinese medicinal materials is not lower than a preset threshold, and to statistically analyze the range of physicochemical indicators, nutrient content, and trace element content of the soil at these sampling points as a standard formula. The sampling module is also used to obtain soil testing data from the planting site of the target medicinal material; The analysis module is also used to compare and analyze the soil data of the target medicinal herb planting site with the standard formula. Based on the comparison and analysis results, the adjustment parameters for adjusting the soil physicochemical indicators and components of the target medicinal herb planting site are determined. After adjusting the soil of the target medicinal herb planting site according to the adjustment parameters, each physicochemical indicator is within the corresponding range, the content of each nutrient is not lower than the lower limit of the corresponding nutrient range, and the content of each trace element is not lower than the lower limit of the corresponding trace element content range, thereby achieving soil improvement of the target medicinal herb planting site.

[0056] In this embodiment, the specific implementation methods of the sampling module and the analysis module can be referred to the description in Embodiment 1 above.

[0057] This embodiment also includes: a GIS data management module, a storage module, and a visualization display module, wherein: The GIS data management module is used to delineate each sampling point and each planting area, and extract the attribute parameters of each delineated plot; the attribute parameters include: plot area and coordinates.

[0058] The storage module is used to store soil testing data, Chinese medicinal herb testing data, standard formulas, adjustment parameters, and plot attribute parameters; The visualization module provides an interface for customized operations, including query operations and information addition operations.

[0059] In a preferred embodiment, the storage module is a MySQL database, and the visualization module is the SQLyog graphical management tool.

[0060] SQLyog is a simple, efficient, and powerful graphical MySQL database management tool. In this embodiment, the SQLyog graphical management tool records and can query the test results of the physicochemical indicators and nutrient content of the soil in the medicinal herb planting area, such as... Figure 3 As shown, the data includes: pH value, organic matter, hydrolyzable nitrogen, available phosphorus, slow-release potassium, readily available potassium content, and detection time.

[0061] The advantage of this database lies in its ability to digitize and categorize key data, facilitating retrieval and processing. Traditional fragmented Excel, Word, and PDF analysis files are prone to loss and confusion; this database is concise, practical, and possesses significant practical value. It can function as an open system, with future additions of modules related to medicinal herb cultivation, such as climate, seeds, seedlings, pesticide use and monitoring, soil disinfection, and soil acidification remediation. This will provide traceable digital evidence for medicinal herb cultivation. Furthermore, it can achieve interoperability with software like Python in the future, enabling web scraping, machine learning of data, identification, and processing. A future app for growers can also be developed to achieve blockchain-based distributed management.

[0062] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
