Description

Technical Field

[0002] In the study of botany and related ecological fields, accurate monitoring of the growth and development of plant roots is crucial. The root system is the key part for plants to absorb nutrients and stabilize plants, and its development directly affects the growth trend of plants and the stability of the ecosystem.

[0003] However, the current technical means for monitoring the growth and development of plant roots have many limitations. On the one hand, most existing monitoring methods focus on the intuitive observation of root morphology, such as checking the appearance of the root system through digging, etc. This practice not only destroys the original growth environment of the plant, but also makes it difficult to achieve continuous and dynamic monitoring. On the other hand, some monitoring with the help of sensors can often only obtain data of limited dimensions, and the comprehensive monitoring of the stress conditions of the roots in the soil and the developmental changes at different growth stages is not comprehensive and accurate enough. Therefore, the above-mentioned monitoring methods for the growth and development of plant roots are difficult to accurately monitor the actual growth conditions of in situ plants while avoiding damage to the roots of in situ plants. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems in the prior art and provide an in-situ and indoor test system and method for force inversion of plant root growth monitoring, so as to accurately monitor the actual growth conditions of in-situ plants without causing damage to the in-situ plants.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 3 As shown, the present invention provides an in-situ and indoor test system for force inversion of plant root growth monitoring, including a loading system 101 and a monitoring system, wherein the loading system 101 is used to apply tension to an in-situ vegetation 102, and the monitoring system is used to monitor the deformation of the in-situ vegetation 102 when subjected to force, and also includes: a test box 103 and simulated vegetation, wherein the test box 103 is filled with test soil; the simulated vegetation includes a single-root similar vegetation 104, a root variable number similar vegetation 106, and a root variable inclination similar vegetation 108; the single-root similar vegetation 104 is arranged in the test soil in the test box 103, and the single-root similar vegetation 104 includes a main root 105; the root variable number similar vegetation 106 is arranged in the test soil in the test box 103, and the root variable number similar vegetation 108 is arranged in the test soil in the test box 103. The test box 106 includes a main root 105 and multiple pairs of secondary roots 107; the similar vegetation with variable root inclination angle 108 is arranged in the test soil in the test box 103, and the similar vegetation with variable root inclination angle 108 includes a main root 105 and multiple pairs of secondary roots 107, and the angle between the secondary root 107 and the main root 105 of the similar vegetation with variable root inclination angle 108 is different from the angle between the secondary root 107 and the main root 105 of the similar vegetation with variable root quantity 106; the loading system 101 is also used to apply tension to the single-root similar vegetation 104, the similar vegetation with variable root quantity 106 and the similar vegetation with variable root inclination angle 108; the monitoring system is also used to monitor and record the deformation of the single-root similar vegetation 104, the similar vegetation with variable root quantity 106 and the similar vegetation with variable root inclination angle 108 when subjected to force.

[0038] As a preferred solution, Figure 3As shown, the simulated vegetation also includes similar vegetation with variable root diameters 2, which is arranged in the test soil in the test box 103, and the similar vegetation with variable root diameters 2 includes a main root 105 and multiple pairs of secondary roots 107.

The loading system 101 is also used to apply tension to the similar vegetation with variable root diameters 2, and the monitoring system is also used to monitor the deformation of the similar vegetation with variable root diameters 2 when subjected to force.

[0039] The working principle of the above embodiment is briefly described:

[0040] The first step: first select a simulated vegetation 8 from a single-root similar vegetation 104, a root-varied number similar vegetation 106, a root-varied inclination similar vegetation 108 or a root-varied diameter similar vegetation 2, and place the simulated vegetation 8 in the test box 103 and center it, then fill the simulated vegetation 8 with test soil evenly and densely around it to simulate the planting state of the in-situ vegetation 102, and finally connect the top of the simulated vegetation 8 to the loading system 101.

[0041] Step 2: Turn on the monitoring system, and aim the monitoring system at the location of the simulated vegetation 8 to record its subsequent pulling deformation.

[0042] Step 3: operate the loading system 101 to apply a pulling force to the simulated vegetation 8 through the loading system 101 , and at the same time, measure the value of the pulling force applied to the simulated vegetation 8 .

[0043] Step 4: In the process of applying the pulling force, the monitoring system records the pulling deformation of the simulated vegetation 8, and gradually establishes a database of numerical evolution according to the deformation of the simulated vegetation 8 when subjected to the pulling force. The database contains data on the deformation of single-root similar vegetation 104, similar vegetation with changed number of roots 106, similar vegetation with changed inclination of roots 108, or similar vegetation with changed diameter of roots 2 when subjected to force.

[0044] Step 5: Move the loading system 101 to the location of the in-situ vegetation 102 , connect the loading system 101 to the in-situ vegetation 102 , and align the monitoring system with the in-situ vegetation 102 .

[0045] Step 6: Apply a pulling force to the in-situ vegetation 102 through the loading system 101. During this process, the value of the pulling force applied to the in-situ vegetation 102 is measured in real time.

[0046] Step 7: While applying the pulling force to the in-situ vegetation 102 , the monitoring system is used to record the pulling deformation of the in-situ vegetation 102 . By comparing the in-situ vegetation 102 with the data in the database, the force value of the in-situ vegetation 102 is inverted, thereby monitoring the root development of the in-situ vegetation 102 .

[0047] The force inversion in-situ and indoor testing system for monitoring plant root growth of the present invention can not only apply a pulling force to the actual growing vegetation in-situ through the corresponding testing system and perform force measurement and inversion to monitor the root growth and development, but also simulate the planting state of the in-situ vegetation 102 with the help of the test box 103, and carry out relevant tests indoors using the simulated vegetation 8. It can monitor the development of the plant root system by establishing a numerical evolution database, etc., covering multiple scene applications, realizing in-situ and indoor multi-scene monitoring, making the monitoring method more comprehensive and flexible, and able to adapt to different needs.

[0048] On the basis of the above embodiments, in order to monitor the root development of the in-situ vegetation 102 more accurately.

[0049] like Figure 2 and Figure 3 As shown, the similar vegetation with variable root quantity 106 includes multiple specifications, and the number of secondary roots 107 of each specification of similar vegetation with variable root quantity 106 is different, the similar vegetation with variable root inclination 108 includes multiple specifications, and the angles between the secondary roots 107 and the main root 105 of each specification of similar vegetation with variable root inclination 108 are different, and the similar vegetation with variable root diameter 2 includes multiple specifications, and the diameters of the main roots 105 or secondary roots 107 of each specification of similar vegetation with variable root diameter 2 are different.

[0050] By setting various specifications of similar vegetation 106 for root quantity changes, similar vegetation 108 for root inclination changes, and similar vegetation 2 for root diameter changes, the richness of data in the numerical evolution database can be enriched, making the monitoring of the in-situ vegetation 102 more comprehensive, thereby making the result of force inversion of the in-situ vegetation 102 more accurate, and thus enabling more precise monitoring of the root development of the in-situ vegetation 102.

[0051] As a preferred solution, Figure 3 As shown, the diameters of the main root 105 and the secondary root 107 of the similar vegetation 2 with various specifications of root variable diameters increase in the same proportion.

[0052] As a preferred solution, Figure 1 and Figure 2As shown, the loading system 101 includes a rectangular frame 301, a lifting mechanism, a hanging platform 302, a hanging rope 303 and a dynamometer 304, the in-situ vegetation 102 or the test box 103 is arranged in the rectangular frame 301, the lifting mechanism is arranged on the rectangular frame 301, the hanging platform 302 is arranged on the lifting mechanism, one end of the hanging rope 303 is connected to the hanging platform 302, and the other end of the hanging rope 303 is provided with a hanging ring 305, the hanging ring 305 is connected to the top of the in-situ vegetation 102, the single similar vegetation 104, the similar vegetation with variable root quantity 106, the similar vegetation with variable root inclination 108 or the similar vegetation with variable root diameter 2, and the dynamometer 304 is arranged on the hanging rope 303, and the dynamometer 304 is used to detect the real-time tension on the hanging rope 303. The lifting ring 305 in the loading system 101 is fixed on the top of the in-situ vegetation 102, the single similar vegetation 104, the similar vegetation with variable number of roots 106, the similar vegetation with variable inclination angle 108 or the similar vegetation with variable diameter 2 to ensure a stable connection. At the same time, the rectangular frame 301 is welded and placed stably, and the components are connected normally. After the rectangular frame 301 is fixed, the lifting platform 302 is driven to rise by the lifting mechanism, thereby pulling the lifting rope 303, and the lifting rope 303 is stretched by force, so as to supply the in-situ vegetation through the lifting ring 305. A pulling force is applied to the vegetation 102, the single similar vegetation 104, the similar vegetation with changed root quantity 106, the similar vegetation with changed root inclination 108 or the similar vegetation with changed root diameter 2. At the same time, the dynamometer 304 is used to measure the value of the pulling force applied by the suspension rope 303 in real time, thereby achieving precise control of the pulling force applied to the in-situ vegetation 102, the single similar vegetation 104, the similar vegetation with changed root quantity 106, the similar vegetation with changed root inclination 108 or the similar vegetation with changed root diameter 2, and further ensuring the accuracy of the inversion result.

[0053] As a preferred solution, Figure 1 and Figure 2As shown, the dynamometer 304 is electrically connected to a data acquisition module 4, the data acquisition module 4 is electrically connected to a processor, the processor is connected to a database, and the processor is electrically connected to the monitoring system. The processor records the deformation data of single-root similar vegetation 104, similar vegetation with changed root quantity 106, similar vegetation with changed root inclination 108, or similar vegetation with changed root diameter 2 when subjected to tension into the database, and then compares the deformation of the in-situ vegetation 102 when subjected to the same tension with the data in the database to invert the development of the root system of the in-situ vegetation 102. The data acquisition module 4 continuously collects the tensile force values ​​monitored by the dynamometer 304, and gradually establishes a numerical evolution database by using the differences in the dynamometer 304 monitoring values ​​caused by changes in the single-root similar vegetation 104, the root number similar vegetation 106, the root inclination similar vegetation 108, or the root diameter similar vegetation 2 in the simulated vegetation 8. Based on the collected pull-out force values ​​and pull-out deformation data, combined with the established numerical evolution database, a machine learning algorithm is used to establish a model, and the root development of the in-situ vegetation 102 corresponding to the similar vegetation is analyzed and inferred by the force value inversion method. Finally, the relevant monitoring data and analysis results are transmitted to the external device for viewing and further research through the data transmission module 901 of the monitoring system. The dynamometer 304 can accurately perform force measurement work, and the wiring harness connection is unobstructed, which can achieve normal communication with the monitoring system. The data acquisition module 4 is ready to receive the pull-out force measurement values ​​from the dynamometer 304. The dynamometer 304 measures the value of the pulling force in real time, and transmits the value back to the data acquisition module 4 through the data transmission module 901. During the application of the pulling force, the monitoring system records the pulling deformation of the in-situ vegetation 102. The data acquisition module 4 continuously collects the monitoring values ​​of the dynamometer 304, and the processor generates data on the deformation of a single similar vegetation 104, a similar vegetation with a root change number 106, a similar vegetation with a root change angle 108, or a similar vegetation with a root change diameter 2 when subjected to tension. The data are recorded in the database. When the in-situ vegetation 102 is inverted, the deformation of the in-situ vegetation 102 when subjected to the same tensile force is compared with the data in the database to invert the development of the root system of the in-situ vegetation 102. The processor is electrically connected to the data transmission module 901. With the help of the data transmission module 901, the collected pulling force values, the pulling deformation of the in-situ vegetation 102, and the root development monitoring results obtained by force value inversion are transmitted to an external storage or analysis device (such as a computer, etc.), so as to facilitate further in-depth research and analysis on the root development of the in-situ vegetation 102.

The synchronous motor 501 is connected to the synchronous lifting screw 502 through a transmission rod. By sending a control instruction to the synchronous motor 501 of the lifting mechanism, the synchronous motor 501 drives the synchronous transmission rod 902 to rotate, thereby driving the synchronous lifting screw 502 to rotate. Under the action of the threaded hole on the rectangular frame 301, the synchronous lifting screw 502 and the hanging platform 302 are driven to rise. The hanging platform 302 drives the hanging wheel 503 to move upward, and the hanging wheel 503 supports and pulls the hanging rope 303, thereby applying an upward pulling force to the hanging ring 305 through the hanging rope 303, so as to stably pull the in-situ vegetation 102, a single similar vegetation 104, similar vegetation with variable root quantity 106, similar vegetation with variable root inclination 108 or similar vegetation with variable root diameter 2.

Then, the anchoring steel plate is connected to the operating platform with the ground anchor bolt 7, so as to ensure the stability of the test box 103 during the test.
