Description

Technical Field

[0001] This utility model relates to the technical field of plant measurement devices, and in particular to a comprehensive measurement device for multiple parameters of plant growth. Background Technology

[0002] A search revealed a Chinese patent, CN 216717195 U, which discloses a plant growth information measuring device. The device includes a circular base and a culture tube mounted on the base. The base has a measuring section and a movable section that slides circumferentially on it. The measuring section includes a first measuring rod and a second measuring rod with graduations. The first measuring rod is vertically rotatably mounted at the top of the movable section, and the second measuring rod is perpendicular to the first measuring rod, with one end sliding along the axial direction of the first measuring rod. This invention uses the first measuring rod to periodically measure the plant's height, and the movable section to move the first measuring rod circumferentially along the outer side of the upper end of the base, facilitating the measurement of plant growth information at different locations within the culture tube. The second measuring rod slides along one side of the first measuring rod; rotating the first measuring rod drives the second measuring rod to rotate, allowing for the measurement of the plant's width. This results in faster and more accurate measurements.

[0003] The aforementioned devices have drawbacks in practical use. These devices and existing devices generally focus on above-ground indicators such as plant height, stem diameter, and leaf area, lacking online or in-situ detection capabilities for underground root length. This forces researchers to completely excavate the plant from the substrate, rinse it with water, and then manually measure it using a ruler or image software. This process not only damages the root structure and consumes manpower, but also makes it impossible to continuously track the dynamic changes in root length of the same plant, severely restricting the accuracy and efficiency of comprehensive evaluation of plant growth. Therefore, it is necessary to improve the devices under the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a multi-parameter comprehensive measurement device for plant growth, in order to solve the problem that existing measurement devices mentioned in the background art lack online or in-situ detection functions for underground root length. This results in researchers having to completely dig out the plant from the substrate, rinse it with water, and then manually measure it with a ruler or image software. This process not only damages the root structure and consumes manpower, but also makes it impossible to continuously track the dynamic changes in root length of the same plant, which seriously restricts the accuracy and efficiency of comprehensive evaluation of plant growth.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A multi-parameter integrated measurement device for plant growth includes

[0013] Preferably, the upper wall of the planting box has two guide slots, an adjusting rod is slidably connected inside the guide slots, and a clamping rod is fixedly connected between the two adjusting rods. There are two clamping rods, and a measuring ruler is fixedly connected to the upper wall of one of the clamping rods.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-4 As shown, this utility model is a multi-parameter comprehensive measurement device for plant growth, including...

[0026] Planting box 1, the planting box 1 is filled with soil, and the front side wall of the planting box 1 is provided with an installation slot;

[0027] Transparent observation panel 2, which is connected to the mounting slot;

[0028] The planting box 1 has two horizontal slots 3 on one side wall, and a sliding rod 4 is slidably connected inside the horizontal slot 3. A scale 5 is fixedly connected between the two sliding rods 4, and a handle 6 is fixedly connected to one side wall of the scale 5.

[0029] As can be seen from the above, the transparent observation panel 2 is embedded in the side wall of the planting box 1. The roots inside the box can naturally extend along the glass plane, and personnel can directly observe the direction of the root tips through the glass without digging out the plant. By holding the handle 6 and pushing the scale 5, the slide bar 4 slides in the horizontal groove 3, and the scale value at the root tip is read in real time, realizing in-situ online measurement of root length. Moreover, the same plant can be tracked multiple times, avoiding errors caused by destructive sampling.

[0030] Depend on Figure 4 It is known that the transparent observation panel 2 is made of glass.

[0031] As can be seen from the above, the glass panel has a light transmittance of ≥91% and no absorption peak in the visible light band, which can reduce the impact of light differences on root growth; at the same time, the glass surface has a hardness of 6.5 Mohs, which makes it less prone to scratches when rubbing against soil particles, ensuring a clear field of view for long-term observation and extending its service life.

[0032] Depend on Figure 1 and Figure 4 It can be seen that both the transverse slot 3 and the slide bar 4 are T-shaped structures.

[0033] As can be seen from the above, the T-shaped transverse groove 3 and the T-shaped slide bar 4 form a tenon-groove fit, which provides lateral sliding freedom while restricting wobbling, so that the scale 5 is always in close contact with the glass wall, preventing parallax caused by the gap between the scale and the root when reading, and improving the root length measurement accuracy to ±0.5mm.

[0034] Depend on Figure 2 It is known that, in order to facilitate leveling and improve measurement accuracy, a base plate 7 is also included, which is fixedly set on the bottom wall of the planting box 1. The bottom wall of the base plate 7 is fixedly connected with an anti-slip rubber pad 8, and the upper wall of the base plate 7 is provided with an installation square opening. A horizontal bubble plate 9 is fixedly installed inside the installation square opening.

[0035] As can be seen from the above, the horizontal bubble plate 9 on the base plate 7 is used to quickly level the planting box 1, ensuring that the box is in a horizontal state and avoiding measurement errors caused by root tropism due to slope; the anti-slip rubber pad 8 forms a high friction interface with the ground, eliminating possible box slippage when pushing the scale 5, and ensuring consistent measurement benchmarks for multiple measurements.

[0036] Depend on Figure 2 and Figure 4 It is known that, in order to facilitate the measurement of the plant diameter, two guide slots 10 are provided on the upper wall of the planting box 1. An adjusting rod 11 is slidably connected inside the guide slot 10. A clamping rod 12 is fixedly connected between the two adjusting rods 11. There are two clamping rods 12, and a measuring ruler 13 is fixedly connected to the upper wall of one of the clamping rods 12.

[0037] As can be seen from the above, the two clamping rods 12 slide within the guide groove 10, which can gently clamp the plant stem from both sides, and the measuring ruler 13 can directly read the stem diameter value; the clamping force can be controlled by the interference damping of the guide groove 10 to avoid damaging the stem tissue, and realize the non-destructive and real-time measurement of the above-ground diameter, which is obtained synchronously with the root length data.

[0038] Depend on Figure 3It is known that, in order to facilitate the measurement of plant height, a vertical groove rod 14 is fixedly connected to one side wall of the planting box 1. A cavity is opened on the upper wall of the vertical groove rod 14. An extension rod 15 is slidably connected inside the cavity. A label plate 16 is fixedly connected to the upper end of the extension rod 15. Scale lines 17 are fixedly provided on the side walls of both the vertical groove rod 14 and the extension rod 15. A limiting component for fixing the extension rod 15 is provided on one side of the vertical groove rod 14.

[0039] The limiting component includes a lead screw 18. The vertical groove rod 14 has an internal threaded slot hole that communicates with the cavity groove on one side wall. The lead screw 18 is movably connected inside the internal threaded slot hole. A knob 19 is fixedly connected to one end of the lead screw 18, and the other end of the lead screw 18 abuts against one side wall of the extension rod 15.

[0040] As can be seen from the above, the extension rod 15 slides up and down in the groove of the vertical groove rod 14, so that the bottom edge of the marking plate 16 lightly touches the top bud of the plant. The scale line 17 on the side wall of the vertical groove rod 14 and the extension rod 15 forms two levels of readings. The height can be locked by pressing the end face of the screw 18 against the extension rod 15, so as to realize the rapid and accurate measurement of plant height. The entire set of above-ground and underground parameters are completed in the same device and at the same time, which greatly improves the efficiency and data consistency of the comprehensive measurement of multiple parameters of plant growth.
