Description

Technical Field

[0001] The present invention belongs to the technical field of fertilizer index monitoring, and more specifically relates to a system and an evaluation method for evaluating comprehensive physiological indexes of fertilizers. Background Art

[0002] In agricultural scientific research and production, the rational selection and use of fertilizers have a vital impact on crop growth and yield. In order to evaluate the comprehensive performance of fertilizers and their specific effects on plant growth, traditional evaluation methods mainly rely on field tests or laboratory test results of specific nutrients obtained through chemical or biological analysis methods. However, although field tests can more realistically reflect the effect of fertilizers in actual applications, they are easily affected by natural environmental factors (such as climate, soil conditions, etc.), making it difficult to ensure the repeatability and accuracy of test results. In addition, field tests have long cycles and high costs, which are not conducive to the rapid screening and optimization of fertilizer formulas.

[0003] Traditional laboratory analysis and testing methods often involve multiple steps, including complex sample pretreatment (such as digestion with sulfuric acid-hydrogen peroxide), chemical reactions, biological reactions, etc., and the entire detection process takes a long time. At the same time, due to the need to use high-quality chemical reagents, biological reagents and high-precision instruments and equipment, the detection cost is relatively high. In addition, the existing detection methods often have many steps, and each step requires strict control of experimental conditions, such as temperature, pH value, reaction time, etc., and multiple washing, centrifugation, separation and other operations are required, which increases the complexity and workload of the experiment, and requires high requirements for operators with relevant professional knowledge and skills to ensure the safety of the experimental process and the accuracy of the test results. The high-precision instruments and equipment required for the above operations, such as high-performance liquid chromatographs and mass spectrometers, are not only expensive, but also require regular maintenance and calibration. Therefore, in practical applications, the existing detection methods are often difficult to popularize to grassroots testing institutions or small laboratories.

[0004] Some organic fertilizers are also accompanied by the growth of probiotics (such as anti-disease and insecticides for diseases such as Huanglongbing and pine wood nematodes) in the soil ecology, which requires comprehensive observation. However, existing technologies mostly measure the number of bacteria and nutrient elements separately, which cannot well reflect the status and changing trends of the entire fertilizer system. For fertilizers whose morphology and onset process are similar to slow-release effects (such as granular slow-release fertilizers), their component detection is particularly complicated. There are also some soil environments such as seaweed fertilizers, whose morphology and onset process are similar to slow-release effects. Whether they exist alone in filtrate (liquid) or solid form, existing detection methods have limitations. In addition, the monitoring of fertilizer decomposition, the number of probiotics and the activity status often relies on complex chemical analysis or microbial culture technology. These methods are not only cumbersome to operate, but also time-consuming and difficult to meet the needs of rapid evaluation.

[0005] Therefore, there is an urgent need for a fertilizer comprehensive physiological index evaluation device and an evaluation method that is easy to operate, has accurate data and a high degree of automation, and can comprehensively consider multiple physiological indicators of the fertilizer to be tested, so as to overcome the defects of the existing technology and meet the needs of modern agricultural production for rapid and accurate evaluation of fertilizers. Summary of the invention

[0006] In view of the above technical problems, the present invention provides a system and an evaluation method for evaluating the comprehensive physiological indicators of fertilizers, in order to provide a comprehensive physiological indicator evaluation device and an evaluation method for fertilizers that can comprehensively consider multiple physiological indicators, is easy to operate, has accurate data and a high degree of automation, thereby improving the accuracy and reliability of fertilizer detection, so as to achieve a comprehensive and accurate evaluation of fertilizer performance, and more effectively identify the advantages and disadvantages of comprehensive physiological indicators of fertilizers, thereby promoting the healthy development of the entire industry.

[0007] To achieve the above objectives, in a first aspect, the present invention provides a system for evaluating comprehensive physiological indicators of fertilizers, comprising:

[0008] at least one culture chamber provided with an irrigation system, temperature, humidity, light and pH sensors;

[0009] A temperature regulating device, connected to the culture chamber, for accurately regulating the indoor temperature;

[0010] A humidity regulating device, connected to the culture chamber, for accurately regulating the indoor humidity;

[0011] A light adjustment device, connected to the culture chamber, for accurately adjusting the light intensity and spectral distribution in the chamber;

[0012] a pH value adjusting device connected to the irrigation system or soil of the culture chamber for accurately adjusting the pH value of the soil or irrigation water;

[0013] A fertilizer application device, connected to the culture chamber, for applying different types of fertilizers to the test plant seedlings;

[0014] An image acquisition device is used to perform non-contact scanning of the growth conditions of fertilizers, soil, test plant seedlings, and pests and diseases in the culture room to obtain real-time images or data;

[0015] The image recognition device is connected to the image acquisition system and is used to recognize and analyze the image acquired by the image acquisition system.

[0016] The present invention fills the gap in the system for evaluating the comprehensive physiological indicators of fertilizers, and provides a hardware system and technical approach for evaluating the comprehensive physiological indicators of fertilizers. Different from the prior art, the above technical scheme provides good hardware conditions for accurately, quickly and comprehensively evaluating the comprehensive physiological indicators of fertilizers through the modular design and system coordination of the culture chamber, temperature regulating device, humidity regulating device, light regulating device, pH regulating device, fertilizer application device, image acquisition device and image recognition device. The device helps to screen out more comprehensive, efficient and environmentally friendly fertilizer formulas, which is not only suitable for the evaluation of comprehensive physiological indicators of fertilizers, but also can be used to study the effects of different fertilizers on plant growth, optimize fertilizer formulas, screen high-efficiency fertilizers and other aspects. Among them, the image acquisition system adopts a non-contact scanning method to avoid the errors and interferences that may be caused by traditional contact measurements. At the same time, the image recognition system can automatically identify and analyze the acquired images, greatly improving the efficiency and accuracy of data processing. The lighting system uses a full-band light source and control device, which can accurately adjust the light intensity, exposure time and light band to meet the needs of different fertilizers and plant growth. It helps to simulate the light changes in the natural environment and improve the accuracy and reliability of the experimental results.

[0017] More preferably, the culture chamber also includes a gas regulating device for regulating the carbon dioxide concentration and oxygen concentration in the culture chamber. By controlling the concentrations of these two key gases, the growth environment of the plant can be further optimized to meet the specific needs of different plants for the gas environment during growth. This can not only improve the growth rate and health of the plant, but also effectively promote the photosynthesis and respiration of the plant, thereby improving the utilization rate of the fertilizer and the yield of the plant. In addition, the application of the gas regulating device also helps to reduce the occurrence of pests and diseases, and provides a more stable and suitable growth environment for the plant. Therefore, this improvement makes the system more perfect in the evaluation of comprehensive physiological indicators of fertilizers, and has higher practical value and application prospects.

[0018] In some embodiments, the fertilizer application device includes a fertilizer storage tank, a fertilizer pipe and a fertilizer controller, and the fertilizer controller automatically applies fertilizer to the test plant seedlings according to a preset fertilization scheme. The applied fertilizer is suitable for liquid, solid, semi-solid or fluid forms. By including a fertilizer storage tank, a fertilizer pipe and a fertilizer controller, the entire fertilization process is highly automated. The fertilizer controller can accurately control the amount and time of fertilizer application according to the preset fertilization scheme, thereby ensuring that the test plant seedlings obtain balanced and appropriate nutrition, which is conducive to their healthy growth. Secondly, this limitation improves the efficiency of fertilizer use and reduces the waste of fertilizer and the negative impact of excessive use on the environment. At the same time, automated fertilization also reduces the burden of manual operation and improves agricultural production efficiency. In addition, this fertilizer application device also has good adaptability and flexibility, and can adjust the fertilization scheme according to different plant seedlings and growth stages to meet the nutritional needs of different crops, which helps to improve the yield and quality of crops. Therefore, such further limitations have broad application prospects in agricultural production.

[0019] In some preferred schemes, the image acquisition device includes a high-definition camera and a sensor, wherein the high-definition camera is used to take images of test plant seedlings, and the sensor is used to measure the growth parameters of the test plant seedlings. The high-definition camera can capture high-definition images of the test plant seedlings, providing researchers with detailed visual information, which helps to accurately judge the growth state and potential problems of plants. At the same time, the sensor can measure the growth parameters of plants in real time, such as height, leaf area, moisture content, etc., and these data provide objective and accurate quantitative basis for subsequent research applications. By combining the functions of high-definition cameras and sensors, researchers can more comprehensively understand the growth of test plant seedlings, thereby formulating more scientific and reasonable cultivation and management measures. In addition, this image acquisition device also has a higher level of automation and intelligence, can reduce the burden of manual monitoring, and improve agricultural production efficiency. Therefore, such further limitation has a wide range of application value in the fields of plant science research, agricultural intelligence, etc.

[0020] In some preferred improvements of the present invention, the image recognition device includes a data processing unit, which is used to process and analyze the image and growth parameters of the test plant seedlings. Such further limitation of the image recognition device has brought about significant improvement in data processing capability and analysis accuracy. The data processing unit can efficiently process and analyze the images captured by the high-definition camera and the growth parameters measured by the sensor, so as to quickly and accurately identify the key information such as the growth status, pest and disease situation and nutritional status of the test plant seedlings. This improvement is conducive to real-time acquisition of plant growth data, timely discovery of problems and taking corresponding management measures, which is conducive to improving the yield and quality of crops. At the same time, through long-term data accumulation and analysis, researchers can also reveal the laws of plant growth and provide powerful data support for plant science research. Therefore, such further limitation has far-reaching significance and application value in the fields of plant science research and agricultural intelligent management.

[0021] Some preferred improvements of the present invention also include a data recording and analysis system for recording and analyzing the environmental conditions in the culture room, the application of fertilizers, the growth and development of the test plant seedlings, and the results of the detection of pests and diseases. This greatly enhances the level of refinement of the culture environment management and plant growth monitoring. The system not only records the environmental conditions (such as temperature, humidity, light intensity, etc.) and the application of fertilizers in the culture room in real time, but also records and analyzes the growth and development of the test plant seedlings (such as plant height, leaf area, biomass, etc.) and the results of the detection of pests and diseases in detail. This comprehensive data recording and analysis helps to accurately trace every detail in the plant growth process, and promptly discover and solve potential growth obstacles. This not only improves the accuracy and reliability of scientific research experiments, but also provides a more scientific decision-making basis for agricultural production, helps to optimize resource utilization, improve crop yield and quality, and promote sustainable agricultural development.

[0022] In some preferred schemes, the system for evaluating the comprehensive physiological indexes of fertilizers also includes an automated control system for automatically adjusting the environmental conditions of the culture room, controlling the working state of the fertilizer application device, the image acquisition device, and the image recognition device according to the preset experimental scheme, and collecting and analyzing experimental data. Integrating the automated control system into the system for evaluating the comprehensive physiological indexes of fertilizers can intelligently and accurately adjust the environmental conditions of the culture room, including temperature, humidity, light, etc., according to the preset experimental scheme, so as to simulate the microenvironment most suitable for plant growth. At the same time, it can also accurately control the working state of the fertilizer application device, the image acquisition device, and the image recognition device to ensure the continuity and accuracy of the experiment. More importantly, the automated control system can collect and analyze experimental data in real time, provide comprehensive and detailed experimental reports for scientific researchers, and greatly improve the experimental efficiency and data quality. This innovative solution not only reduces labor costs, but also improves the accuracy and reliability of scientific research, injecting new vitality into fertilizer research and agricultural production.

[0023] In some preferred schemes, the temperature regulating device includes a heater and a cooler, which can automatically adjust the temperature in the culture chamber according to a preset temperature range to ensure that the test plant seedlings grow under the optimum growth temperature conditions. In this way, the system of the present invention can automatically adjust the temperature in the culture chamber according to a preset temperature range, and this design brings significant advantages and progress. By accurately controlling the temperature, the device can ensure that the test plant seedlings grow under the optimum growth temperature conditions, which not only promotes the normal growth and development of the plant, but also improves the stability and consistency of its physiological indicators. In addition, the automatic adjustment function reduces the frequency of manual intervention, reduces the difficulty of operation and error, and makes the experimental process more efficient and reliable. This preferred scheme not only improves the accuracy and repeatability of scientific research experiments, but also provides more sophisticated temperature management means for agricultural production, helps to optimize the crop growth environment, improves yield and quality, and promotes the progress of agricultural science and technology.

[0024] In some preferred schemes, the light regulating device includes a light source and a light intensity controller, which can automatically adjust the light intensity and spectral distribution according to the photosynthesis requirements and growth stage of the test plant seedlings to promote the healthy growth of the test plant seedlings. By accurately regulating the light, the device not only meets the different needs of plants for light at different growth stages, but also promotes the photosynthesis and growth and development of plants, and improves the health and physiological indicators of plants. In addition, the automatic adjustment function reduces the complexity and errors of manual operation, making the experimental process more intelligent and efficient. This preferred scheme not only improves the accuracy and reliability of scientific research experiments, but also provides a more scientific means of light management for agricultural production, which helps to optimize crop growth conditions, improve yield and quality, and promote sustainable agricultural development.

[0025] The present invention also provides a method for evaluating comprehensive physiological indicators of fertilizers using the system of the present invention, comprising the following steps:

[0026] S1. Prepare several groups of test plant seedlings, with the same number of seedlings in each group and similar growth conditions;

[0027] S2, placing each group of test plant seedlings in the culture chamber of the system, and applying a different fertilizer in each culture chamber;

[0028] S3. According to the growth requirements of the test plant seedlings and the purpose of the experiment, the environmental conditions in each culture room are accurately set and controlled through the temperature regulating device, humidity regulating device, light regulating device and pH regulating device of the system;

[0029] S4. During the set experimental period, regularly use the image acquisition device of the system to acquire real-time images or data including the growth conditions of fertilizers, soil, test plant seedlings, and pests and diseases;

[0031] S6. Based on the recorded results of step S4 and step S5, comprehensively evaluate the effects of different fertilizers on the growth and development and disease and pest resistance of the test plant seedlings, and obtain a comprehensive physiological index evaluation result of the fertilizer.

[0032] Different from the prior art, the method provided by the present invention can accurately set and control the environmental conditions in the culture room through the temperature, humidity, light and pH value adjustment devices of the system, ensure the consistency and repeatability of the experimental conditions, thereby improving the accuracy and reliability of the experimental results. Not only pay attention to the growth of plants, but also collect data on fertilizers, soil, pests and diseases in real time through image acquisition devices, and combine image recognition devices for intelligent analysis to achieve a comprehensive evaluation of comprehensive physiological indicators of fertilizers. This comprehensive and intelligent data collection and analysis method greatly improves the efficiency and accuracy of the experiment. The entire evaluation process is highly automated, from environmental condition setting, data collection to result analysis, reducing manual intervention, reducing operational difficulty and errors, and improving experimental efficiency. The method can comprehensively evaluate the effects of different fertilizers on plant growth and development and resistance to pests and diseases, provides a scientific basis for fertilizer research and development and agricultural production, helps to optimize fertilizer formulas, improve crop yields and quality, and promote sustainable agricultural development. Therefore, the method of the present invention is superior to the prior art in terms of accuracy, comprehensiveness, efficiency and scientificity, and provides new ideas and means for the comprehensive physiological index evaluation of fertilizers.

The term "embodiment" appearing in various places in the specification does not necessarily refer to the same embodiment, nor does it particularly limit its independence or association with other embodiments. In principle, in the present application, as long as there is no technical contradiction or conflict, the various technical features mentioned in the embodiments can be combined in any way to form a corresponding implementable technical solution.

[0048] Unless otherwise defined, the technical terms used in this document have the same meanings as those generally understood by those skilled in the art to which this application belongs; the use of relevant terms in this document is only for describing specific embodiments and is not intended to limit this application.

[0049] In the description of this application, the term "and / or" is an expression used to describe the logical relationship between objects, indicating that three relationships may exist, for example, A and / or B, which means: A exists, B exists, and A and B exist at the same time. In addition, the character " / " in this article generally indicates that the objects before and after are in an "or" logical relationship.

[0050] In the present application, terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship of quantity, priority or sequence between these entities or operations.

[0051] Without further limitations, in this application, the words "include", "comprises", "has" or other similar expressions used in the sentences are intended to cover non-exclusive inclusion. These expressions do not exclude the presence of additional elements in the process, method or product including the elements, so that the process, method or product including a series of elements may include not only those limited elements, but also other elements not explicitly listed, or also include elements inherent to such process, method or product.

[0052] Similar to the understanding in the Examination Guidelines, in this application, expressions such as "greater than", "less than", "exceed" and the like are understood to exclude the number itself; expressions such as "above", "below", "within" and the like are understood to include the number itself. In addition, in the description of the embodiments of this application, "multiple" means more than two (including two), and similar expressions related to "multiple" are also understood in this way, such as "multiple groups", "multiple times", etc., unless otherwise clearly and specifically limited.

For example, the "connection" can be a fixed connection, a detachable connection, or an integrated setting; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. For technicians in the technical field to which the present application belongs, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0055] In the leaf metabolomics study of citrus Huanglongbing, it was found that infection with citrus Huanglongbing often affects the starch metabolism pathway, amino acid metabolism pathway, fat metabolism pathway and sugar metabolism pathway of the leaves. Therefore, suitable markers can be selected according to the above-mentioned metabolic pathways. However, since the detection of most markers requires the operator to have high experimental operation capabilities and requires high and expensive equipment, how to achieve a relatively accurate preliminary judgment of citrus Huanglongbing through simple methods is a technical problem that urgently needs to be solved.

[0056] Due to long-term engagement in agricultural science theory research and production services, the field tests or laboratory analyses used in the comprehensive performance evaluation of existing fertilizers have their own shortcomings and problems. For example, the field test cycle is long and the cost is high, which is not conducive to the rapid screening and optimization of fertilizer formulas; the traditional laboratory analysis and testing methods are complex, time-consuming, and costly, and require operators with relevant professional knowledge and skills, making it difficult to ensure the accuracy, safety, effectiveness, and consistency of the test and analysis results. For fertilizers with complex ingredients, special indicators are often used for analysis, which lacks systematicity and objectivity.

[0057] Based on this, the inventor combined the principle of seed vertical plate germination test to evaluate the comprehensive physiological indicators of fertilizers, which not only solved the problem of one-sided evaluation methods in the prior art, but also expanded the fertilizers to be tested to various forms such as liquid, fluid, and solid. It can also adjust the bacterial agents in fertilizers for seed germination tests based on the characteristics of certain plant diseases and pests, in order to obtain a more optimized, harmless, green and environmentally friendly disease and pest resistance solution.

[0058] In the present invention, unless otherwise specified, conventional instruments, equipment, reagents, microorganisms or methods available from public channels in the art are used.
