Description

Technical Field

[0001] This application relates to the field of tobacco agricultural experimental tools, and in particular to a tag for testing the leaf position of tobacco plants. Background Technology

[0002] In current tobacco scientific research and breeding practices, the identification and trait recording of tobacco plants mainly rely on traditional marking methods, namely a combination of ordinary plastic tags and cable ties. However, this simple device has revealed significant shortcomings when applied in the complex environment of the field, for example:

[0003] 1. Easy to fall off: During the growth of tobacco plants, the petioles continue to thicken, while traditional rigid tie straps lack elasticity and adjustment capabilities, which will continuously cut into the petiole tissue, forming mechanical stress. The petioles are compressed, which will lead to tissue necrosis. The tag fall-off rate often exceeds 30% in field trials, resulting in the loss of data during key growth periods.

[0004] 2. Damage to tobacco plants: During the fixing process, metal wires or nylon ropes will continuously rub against the epidermis of the petiole, damaging the epidermal wax layer and cuticle layer, forming micro-wounds. In high temperature and high humidity environments, these wounds are very likely to become entry points for pathogens such as black shank, causing diseases.

[0005] 3. Vague positioning: Traditional labeling usually only marks the plant number and fails to achieve precise positioning at the leaf level, such as specific leaf positions like L3 and L5. This makes it impossible for researchers to accurately track the developmental dynamics, chemical composition changes or disease resistance differences of specific leaves, and cannot meet the needs of refined experiments.

[0006] Although various crop identification tags have been developed using existing technologies, they still cannot effectively solve the aforementioned problems. For example, patent CN206558127U discloses an environmentally friendly crop tag, which includes a marking part, a connecting part, and a fixing part connected in sequence. Multiple first adjustment structures are arranged at intervals on the connecting part from the end near the fixing part to the end away from the fixing part. A second adjustment structure is provided on the fixing part. The first and second adjustment structures are connected to form a loop between the connecting part and the fixing part, which is used to fit the crop. This environmentally friendly crop tag can change the size of the loop to suit different crops, and the size of the loop can be adjusted according to the growth and development of the crop, ensuring that the loop always fits the stem of the crop and preventing damage to the tag due to an excessively small loop. While this crop tag solves the problem of easy detachment through its adjustable loop, it does not explicitly provide a design to reduce continuous friction and cannot pinpoint the exact leaf position, thus failing to meet the needs of refined testing. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a tag for tobacco leaf position testing, which can achieve non-destructive fixation of petioles and precise leaf position marking, and is suitable for tobacco quality traceability, batch harvesting optimization, and disease research.

[0008] To achieve the above and related objectives, this utility model provides a tag for tobacco leaf position testing, including a tag body and a radial adaptive adjustment buckle. The tag body has a double-layer structure and its upper part has a trapezoidal arc anti-slip groove for conforming to the physiological morphology of the tobacco leaf petiole. The radial adaptive adjustment buckle is set on the tag body near the trapezoidal arc anti-slip groove so as to fix the tag body on the target leaf position of the tobacco plant through the radial adaptive adjustment buckle.

[0009] Furthermore, the main body of the tag consists of a surface layer and a bottom layer. The surface layer has a writable marking area, and the bottom layer has an NFC chip.

[0010] Furthermore, the inner wall of the trapezoidal arc anti-slip groove is evenly distributed with anti-slip teeth, which are inclined.

[0011] Furthermore, the anti-slip teeth are made of silicone.

[0012] Furthermore, the inner diameter of the upper edge contour arc of the trapezoidal arc anti-slip groove is smaller than the inner diameter of the lower edge contour arc.

[0013] Furthermore, the radially adaptive adjustment buckle is made of PETG plastic.

[0014] Furthermore, the elastic modulus of the radially adaptive adjusting buckle is ≥2.0 GPa.

[0015] Furthermore, the radial adaptive adjustment buckle is provided with a stress relief groove, which includes two rows of semi-circular arched buckle arrays located on both sides of the buckle root, and each row of semi-circular arched buckle arrays includes multiple staggered arched engagement heads.

[0016] Furthermore, the opening and closing gap of the radial adaptive adjustment buckle is adjustable, with an adjustment range of 2.5mm to 3.0mm.

[0017] Furthermore, multiple information labeling areas are also set on the surface.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] This utility model tag is applicable to marking the leaf position of tobacco plants, and is especially suitable for tobacco research scenarios that require long-term locational observation or batch harvesting.

[0020] This invention utilizes a trapezoidal arc anti-slip groove to fit the physiological morphology of the tobacco leaf petiole's groove, and its inner wall is equipped with anti-slip teeth to prevent the tag from sliding, solving the problem of the tag easily falling off and achieving non-destructive fixation of the leaf petiole; it uses a radial adaptive adjustment buckle to flexibly adjust according to the thickness of the leaf veins, adapting to the leaf petiole diameter at different growth stages, solving the problem of traditional tagging damaging the tobacco plant; it uses a double-layer design of the tag body, through an NFC chip and multiple information calibration areas, to accurately calibrate the leaf position, solving the problem of ambiguous positioning in traditional tagging.

[0028] Unless otherwise defined, all technical and / or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should be understood that certain features of this invention (described in the context of separate embodiments for clarity) may also be provided in combination in a single embodiment. Conversely, multiple features of this invention (described in the context of a single embodiment for brevity) may also be provided separately or in any suitable combination or, where appropriate, in any other described embodiment of this invention. Certain features described in the context of various embodiments will not be considered essential features of those embodiments unless the embodiment is inoperable without those elements. The present invention is further illustrated below by specific examples; however, it should be noted that the specific process conditions and results described in the embodiments of this invention are for illustrative purposes only and should not be construed as limiting the scope of protection of this invention. All equivalent changes or modifications made in accordance with the spirit and essence of this invention should be covered within the scope of protection of this invention.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a tag for tobacco leaf position testing, including a tag body 1 and a radial adaptive adjustment buckle 2. The tag body 1 has a double-layer structure and its upper part has a trapezoidal arc anti-slip groove 3 for conforming to the physiological morphology of the tobacco leaf petiole. The radial adaptive adjustment buckle 2 is set on the tag body 1 near the trapezoidal arc anti-slip groove 3 so as to fix the tag body 1 on the target leaf position of the tobacco plant through the radial adaptive adjustment buckle 2.

[0030] Furthermore, this application does not limit the shape and specifications of the tag body 1, but sets them according to actual production needs, such as a rectangular tag body 1. The tag body 1 of this application adopts a double-layer structure, including a top layer and a bottom layer. The top layer is provided with a writable marking area, and the bottom layer is provided with an NFC chip. The writable marking area is compatible with oil-based pens, and information such as plant number and leaf position can be written in the marking area with an oil-based pen. Information such as plant number, leaf position, and installation date can also be recorded through a mobile phone NFC reader. Furthermore, the top layer is also provided with multiple information marking areas. For example, a leaf position area is set in the upper part of the top layer for marking leaf position; a plant number area is set in the lower part of the top layer for marking plant number; and a tobacco variety area can also be set for marking tobacco variety type, such as Chongqing Qianjiang Yunyan. The bottom layer of this application embeds an NFC chip for storing digital information such as plant number, leaf position, and date. The NFC chip can be of the NTAG216 type or similar, and its packaging temperature resistance rating is -25℃ to 85℃.

[0031] Furthermore, such as Figure 2As shown, the radius of curvature R of the trapezoidal arc anti-slip groove 3 in this application is 1.5mm, matching the natural curvature of the tobacco leaf petiole. The inner diameter of the upper edge contour arc of the trapezoidal arc anti-slip groove 3 is smaller than that of the lower edge contour arc. Specifically, the inner diameter of the upper edge contour arc is 5mm~6mm, and the inner diameter of the lower edge contour arc is 8mm~10mm, which can fit the physiological morphology of the groove of the tobacco leaf petiole, making the two fit better and more convenient to use. Furthermore, the inner wall of the trapezoidal arc anti-slip groove 3 is evenly distributed with anti-slip teeth 31. The anti-slip teeth 31 have an inclined structure with an inclination angle of 30° and a tooth height of 0.5mm, which can effectively prevent bidirectional slippage, making the fixation more reliable and protecting the petiole epidermis to avoid damage to the tobacco plant. The anti-slip teeth 31 in this application are made of silicone, which can further increase the friction and prevent the tag from slipping.

[0032] Furthermore, the radial adaptive adjustment buckle 2 of this application is made of PETG plastic, and its elastic modulus is ≥2.0 GPa. The moderately elastic PETG plastic of this application can generate sufficient clamping force through deformation, and its low shrinkage rate and dimensional stability help maintain accuracy, ensuring the reliability of the buckle's adaptive adjustment and preventing the tag from loosening and falling off. In addition, PETG plastic can withstand the erosion of pesticides, fertilizers, or rainwater in the field, adapt to repeated opening and closing, and has a long service life.

[0033] Furthermore, such as Figure 3 As shown, the radial adaptive adjustment buckle 2 of this application is provided with a stress relief groove 21. The stress relief groove 21 includes two rows of semi-circular arched buckle arrays located on both sides of the buckle root. Each row of semi-circular arched buckle arrays includes multiple staggered arched engagement heads. The width of the stress relief groove 21 of this application is 0.8mm. The stress relief groove 21 can significantly reduce the stress peak at the root of the radial adaptive adjustment buckle 2, preventing it from breaking due to repeated bending, improving its fatigue life, and ensuring that the radial adaptive adjustment buckle 2 can still provide a stable and reliable radial clamping force during long-term use, preventing the tag from loosening and falling off. The staggered semi-circular arched buckle array of arched engagement heads can better adapt to forces in different directions, enabling the radial adaptive adjustment buckle 2 to maintain structural stability when subjected to multi-dimensional vibration or impact, and providing a larger elastic deformation space for the buckle, thereby adapting to a wider range of blade diameters.

[0034] Furthermore, the opening and closing gap of the radial adaptive adjustment buckle 2 in this application is adjustable, with an adjustment range of 2.5mm to 3.0mm, which is suitable for petiole diameters (3mm to 8mm) at different growth stages.

[0035] Furthermore, the labeling in this application enables non-destructive fixation of petioles and precise labeling of leaf positions, which is applicable to tobacco quality traceability (linking soil EC values ​​and light intensity sensor data), batch harvesting optimization (automatic sorting and curing batches based on NFC data), disease research (marking specific leaf positions for pathogen inoculation and observation), etc.

[0036] Furthermore, this application provides an exemplary method of listing and using the listing:

[0037] Example 1

[0038] (1) Signage installation: such as Figure 4 As shown, during the tobacco harvesting period, select the target leaf and place the petiole at the bottom of the trapezoidal arc anti-slip groove 3; gently press the radial adaptive adjustment buckle 2 wings so that the radial adaptive adjustment buckle 2 passes over the thickest part of the petiole and then resets and locks.

[0039] (2) Information entry: Write the following in the information marking area with an oil-based pen: Plant No. 015, Leaf position L3 (indicating the 3rd leaf of the 15th plant); or enter the following through a mobile phone NFC reader: {Plant No.: 015, Leaf position: 3, Installation date: 2024-05-01}.

[0040] (3) Harvesting and data association: The petioles are cut off directly during harvesting and the leaves are tagged and enter the curing process with the tobacco leaves; the leaf position information is obtained by scanning the NFC chip and associated with the subsequent chemical composition detection data.

[0041] The test results show that the labeling method is effective and suitable for large-scale application. The results are shown in Table 1 below:

[0044] (Note: Data source: 2024 rainy season field experiment in Yunnan tobacco-growing area (n=3000 plots))

[0045] As shown in 1, compared with traditional tags, the tag application has a significantly lower detachment rate, higher fixing reliability, and is convenient and quick to install and easy to use.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
