Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a plant root growth detection device, belonging to the technical field of plant growth detection. Background Technique

[0002] Plant roots are active absorption and synthesis organs. The growth condition and vitality level of roots directly affect the nutritional status and yield level of the above-ground part. The morphological distribution of plant roots in the growth medium affects the absorption of nutrients and water by plants, and thus affects the growth of plants. Therefore, it is necessary to obtain the root images of plants and construct a three-dimensional model of plant roots to study the growth status of plant roots.

[0003] In the prior art, for example, a plant root growth detection device disclosed in the patent with publication number CN112305157A, including a cup sleeve, a cup body, a cup cover and a graduated cylinder, can intuitively convert the growth of the scale on the graduated cylinder into the growth length of the root system. It can realize that the growth of the root system causes the liquid level in the measuring cavity to rise, protect the plant roots from being affected by external light during growth, and can indirectly observe the growth of the roots of the plant in all directions in the cup body. However, although this detection method can avoid taking out the plant roots from the soil, since the soil will deform due to different water contents, the increase in the scale on the graduated cylinder does not fully represent the characteristic of the volume increase when the plant roots grow, so the actual detection result is inaccurate. Another device disclosed in the patent with publication number CN112970442A, a high-pressure propagator capable of detecting the growth of plant roots, can clamp the plant through a clamping device, fix the device on the branch to be pruned, scrape off the cambium of the branch, and the user can add the medium into the device, so that the part where the cambium is scraped off is wrapped by the medium. As the plant grows, the root hairs will grow towards the direction with air and water. The closed space is connected to the outside through several small through holes and is provided with a shielding net with a certain mesh number to prevent soil leakage. As the root hairs grow outwards, they will gradually push the detection block, and the growth of the root hairs can be detected. When the detection block moves to a certain position, the indicating device will inform the user that the root hairs have grown to a certain extent, which can effectively improve the root strength of the high-pressure branches and improve the propagation success rate. However, in each detection, the plant roots need to be separated from the soil, and then after the detection is completed, the plant roots need to be buried in the soil again. This method will affect the subsequent normal growth of the roots, that is, it is not conducive to the complete growth detection of plant roots. In addition, the prior art can also use the minirhizotron technology for non-destructive monitoring and analysis of root dynamics. Although this method does not need to take out the plant roots from the soil, if the detection microtubes are inserted into the soil multiple times at multiple positions, it will also have a greater impact on the normal growth of plant roots, and the actual detection also has many deficiencies. Content of the Utility Model

[0004] The utility model provides a plant root growth detection device to solve the problem that the prior art cannot simultaneously meet the detection accuracy during the detection process and avoid affecting the growth of plant roots.

[0005] The utility model realizes the above object through the following technical solutions: a plant root growth detection device, including a transparent growth tank, a base, a picture taking camera and a root scanning microtube. The transparent growth tank is placed on the base, and the transparent growth tank is filled with transparent growth soil for planting plants. The picture taking camera is arranged on one side of the transparent growth tank, and the root scanning microtube is inserted into the transparent growth soil.

When the plants grow to a certain stage and the plant roots are in a developed state, the pictures taken by the picture taking camera cannot accurately detect the plant root conditions. The root scanning microtube can be further inserted into the transparent growth soil to perform in-situ online scanning imaging on the root parts that cannot be accurately detected by the taken pictures, that is, the combination of the two methods is used to achieve accurate detection of plant roots, and the impact on the soil is greatly reduced to ensure that the plants can grow normally in a soil environment with a lower degree of damage;

[0006] A base is arranged below the transparent growth tank.

The root scanning microtube is movably connected to the front end of the movable push rod. A threaded rotating rod is vertically connected between the two ends of the C-shaped support rod. A shooting detection block is threadedly connected to the rod body of the threaded rotating rod, and a picture taking camera is connected to the side of the shooting detection block close to the tank wall of the transparent growth tank. When detecting the plant roots by taking pictures, the transparent growth tank can rotate, and at the same time, the shooting detection block drives the picture taking camera to move up and down, so as to form a spiral shooting of the transparent growth tank to ensure a comprehensive shooting of the plant roots. When it is necessary to perform scanning imaging detection on the plant roots, the movable push rod can be pushed to different positions and cooperate with the rotation of the transparent growth tank, so that the root scanning microtube can be inserted into the transparent growth soil from different positions to ensure that the unclear internal position of the soil during shooting can be accurately found, and then the mutual cooperation of the two detection methods can be used to accurately detect the growth conditions of the plant roots.

[0015] 1. By setting up a transparent growth tank, a picture-taking camera, and a root-scanning microtube, when growing plants through transparent growth soil, the roots of the plants can be observed from the outside during the growth process. In the initial stage of plant growth when the roots are underdeveloped, the picture-taking camera can be used to take pictures of the plant roots to detect the plants based on the taken pictures. When the plants grow to a certain stage and the roots are well-developed, the pictures taken by the picture-taking camera cannot accurately detect the root conditions of the plants. Further, the root-scanning microtube can be inserted into the transparent growth soil to perform in-situ online scanning imaging on the root parts that cannot be accurately detected in the taken pictures. That is, through the combination of the two methods, accurate detection of plant roots can be achieved, and the impact on the soil can be greatly reduced to ensure that the plants can grow normally in a soil environment with a relatively low degree of damage.

[0016] 2. By setting up a base, a rotating bottom plate, a C-shaped support rod, and a movable push rod, when detecting the plant roots by taking pictures, the transparent growth tank can rotate, and at the same time, the picture-taking detection block drives the picture-taking camera to move up and down, so as to form a spiral shooting of the transparent growth tank to ensure a comprehensive shooting of the plant roots.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model. Embodiment 1

[0028] As shown in Figure 1 , Figure 2 and Figure 3 shown, a plant root growth detection device includes a transparent growth tank 1, a base 3, a picture shooting camera 6 and a root system scanning microtube 8. The transparent growth tank 1 is placed on the base 3. The transparent growth tank 1 is filled with transparent growth soil 2 for planting plants. The picture shooting camera 6 is arranged on one side of the transparent growth tank 1. The root system scanning microtube 8 is inserted into the transparent growth soil 2. When planting plants through the transparent growth soil 2, the roots of the plants can be observed from the outside during the growth process. In the initial stage of plant growth, when the plant roots are underdeveloped, the picture shooting camera 6 can be used to continue shooting the roots of the plants to detect the plants according to the taken pictures. When the plants grow to a certain stage and the plant roots are in a developed state, the pictures taken by the picture shooting camera 6 cannot accurately detect the root system of the plants. The root system scanning microtube 8 can be further inserted into the transparent growth soil 2 to perform in-situ online scanning imaging on the root system parts that cannot be accurately detected by the taken pictures, that is, to achieve accurate detection of the plant roots through the combination of the two methods, and greatly reduce the impact on the soil to ensure that the plants can grow normally in a soil environment with a lower damage degree;

[0029] Among them, for the transparent growth soil 2, the soil prepared by a transparent soil material, its preparation method and application disclosed in the publication number CN117546758A is used. The natural polymer hydroxyethyl cellulose is dissolved in water to obtain a hydroxyethyl cellulose solution; the low-acyl plant gel is added to the hydroxyethyl cellulose solution and stirred evenly. The uniformly dispersed mixed solution is heated in a water bath for half an hour to obtain a clear and transparent polymer mixed solution. Wait for it to cool to room temperature to form a transparent viscous liquid, and configure a magnesium chloride hexahydrate and MS mixed nutrient salt solution as a coagulation bath. Hydrogel particles with uniform size, shape and properties are prepared by the drop sphere method, and a natural-based transparent soil is prepared for root culture and observation;

[0030] A base 3 is provided below the transparent growth tank 1. The upper end surface of the base 3 is rotatably connected with a rotating bottom plate 32, and the transparent growth tank 1 is placed on the rotating bottom plate 32. One side of the base 3 is vertically connected with a C-shaped support rod 4. The upper end of the C-shaped support rod 4 is horizontally penetrated by a movable push rod 7. The root scanning microtube 8 is movably connected to the front end of the movable push rod 7. A threaded rotating rod 5 is vertically connected between the two ends of the C-shaped support rod 4. A photographing and detecting block 61 is threadedly connected to the rod body of the threaded rotating rod 5. And a picture taking camera 6 is connected to the side of the photographing and detecting block 61 close to the tank wall of the transparent growth tank 1. When detecting the picture of the plant roots by taking pictures, the transparent growth tank 1 can rotate, and at the same time, the photographing and detecting block 61 drives the picture taking camera 6 to move up and down. Furthermore, a spiral photographing of the transparent growth tank 1 can be formed to ensure a comprehensive photographing of the plant roots. And when it is necessary to perform scanning imaging detection on the plant roots, the movable push rod 7 can be pushed to different positions and cooperate with the rotation of the transparent growth tank 1. Furthermore, the root scanning microtube 8 can be inserted into the transparent growth soil 2 from different positions to ensure that the unclear internal position of the soil for photographing can be accurately found. Furthermore, the mutual cooperation of the two detection methods can be realized to accurately detect the growth condition of the plant roots. Example Two

[0031] Improved on the basis of Example One:

[0032] As Figure 2 and Figure 3 shown, a groove 31 is opened on the upper surface of the base 3, and the rotating bottom plate 32 is placed flat in the groove 31. When the transparent growth tank 1 is placed on the rotating bottom plate 32, the bottom end of the transparent growth tank 1 is located in the groove 31. Furthermore, the placement position of the transparent growth tank 1 can be limited to reduce the interference of adverse factors during the growth detection of the plant roots.

[0033] Further, an inner cavity 33 is formed inside the base 3. At the center of the lower plate surface of the rotating bottom plate 32, a supporting rotating rod 34 is vertically connected. The supporting rotating rod 34 is inserted into the inner cavity 33 and is rotatably connected to the bottom surface of the inner cavity 33. A driving motor 9 is also fixedly connected to the bottom surface of the inner cavity 33. The bottom end of the threaded rotating rod 5 is inserted into the inner cavity 33, and the rotating shaft of the driving motor 9 is fixedly connected to the threaded rotating rod 5 coaxially. The driving motor 9 can drive the threaded rotating rod 5 to rotate, and the rotating bottom plate 32 can rotate synchronously through the rotation of the supporting rotating rod 34, that is, a spiral shooting of the transparent growth tank 1 by the picture-taking camera 6 can be realized.

[0034] Further, a driving runner 91 is sleeved on the rod body of the threaded rotating rod 5 located inside the inner cavity 33, and a driven runner 92 is sleeved on the rod body of the supporting rotating rod 34. The driving runner 91 and the driven runner 92 are at the same height, and a transmission belt 93 is sleeved between the driving runner 91 and the driven runner 92. That is, while the driving motor 9 drives the threaded rotating rod 5 to rotate, the supporting rotating rod 34 can also be driven to rotate by the transmission belt 93, that is, it can be ensured that the rotation of the transparent growth tank 1 is synchronized with the up and down movement of the picture-taking camera 6.

[0035] As Figure 1 、 Figures 4 to 8 shown, a limiting sliding groove 41 is formed in the vertical rod body of the C-shaped support rod 4. A limiting sliding block 62 is integrally connected to the side of the shooting detection block 61 close to the C-shaped support rod 4. The limiting sliding block 62 is movably clamped in the limiting sliding groove 41. When the threaded rotating rod 5 rotates to drive the shooting detection block 61 to move up and down, it can be ensured that the shooting detection block 61 will not rotate accordingly, that is, the shooting detection block 61 is limited to move only in the vertical direction.

[0036] Further, a horizontally arranged push rod through hole 42 is formed at the upper end of the C-shaped support rod 4. A movable push rod 7 is movably inserted through the push rod through hole 42. A damping rubber ring 43 is embedded in the inner wall of the push rod through hole 42, and the damping rubber ring 43 is closely attached to the rod body of the movable push rod 7. Under the action of the opened push rod through hole 42, the movable push rod 7 can move along the horizontal direction, and under the action of the damping rubber ring 43, the position of the movable push rod 7 after moving can be limited and fixed to ensure the accuracy of the insertion position of the root system scanning microtube 8 when the root system scanning microtube 8 is used for detecting the growth root system of plants.

[0037] Further, the photographing and detecting block 61 is provided with a vertically-shaped threaded through hole 63, and the threaded rotating rod 5 is in threaded engagement with the threaded through hole 63. Limit switches 64 are installed at the upper and lower ends of the photographing and detecting block 61, and the limit switches 64 are in signal transmission connection with an externally provided detection control terminal, so that the photographing and detecting block 61 can move up and down smoothly through thread fitting. When it moves to the end position, the upper and lower limit switches 64 can respectively issue in-place instructions to control the driving motor 9 to stop providing driving force.

[0038] As Figure 1 and Figure 9 shown, a positioning seat 71 is provided at the front end of the movable push rod 7. A positioning through hole 73 is formed in the positioning seat 71. A universal joint 72 is connected to the front end of the movable push rod 7, and the movable push rod 7 is connected to the positioning seat 71 through the universal joint 72, so that the angle of the positioning seat 71 can be adjusted. Furthermore, when the root scanning microtube 8 passes through the positioning through hole 73, it can be inserted into the transparent growth soil 2 at a corresponding orientation or angle. After determining the insertion angle, the root scanning microtube 8 can be inserted to avoid the situation of secondary insertion due to large deviation in the position inserted into the soil.

[0039] Working principle: In the initial stage of plant growth when the plant roots are underdeveloped, the picture-taking camera 6 can be used to continue taking pictures of the plant roots to detect the plant roots according to the taken pictures. When the plant grows to a certain stage and the plant roots are in a developed state, the pictures taken by the picture-taking camera 6 cannot accurately detect the plant root conditions. Further, the root scanning microtube 8 can be inserted into the transparent growth soil 2 to perform in-situ online scanning imaging on the root parts that cannot be accurately detected by the taken pictures, that is, through the combination of the two methods to achieve accurate detection of the plant roots, and greatly reduce the impact on the soil to ensure that the plant can grow normally in a soil environment with a lower degree of damage.
