Description

Technical Field

[0001] This utility model relates to the field of cucumber salt tolerance identification technology, specifically a multispectral detection device for cucumber salt tolerance identification. Background Technology

[0002] Cucumber salt tolerance assessment refers to the systematic evaluation and analysis of cucumber growth, physiological and biochemical responses, and final yield under different salt stress environments using a series of scientific and standardized methods. This objectively assesses and distinguishes the ability of different cucumber varieties to tolerate saline soil or high-salt irrigation water. The multispectral detection device used for cucumber salt tolerance assessment is a specialized optical measurement device for rapid, non-destructive, and high-throughput evaluation of the physiological state of cucumber plants under salt stress. It rapidly and non-destructively assesses the physiological state of cucumber plants by analyzing changes in the spectral information of cucumber leaves or canopy under salt stress.

[0003] During the laboratory testing of cucumber salt tolerance, the undrained culture tanks are extremely heavy. Manual handling can easily lead to muscle strain, and the tanks are prone to slipping, damaging the equipment and injuring the operators, posing certain safety risks. Utility Model Content

[0004] The purpose of this invention is to provide a multispectral detection device for identifying the salt tolerance of cucumbers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multispectral detection device for identifying the salt tolerance of cucumbers, comprising an experimental rack, a cultivation trough, a column, and a multispectral detection camera. The cultivation trough is connected to both sides of the top of the experimental rack, and a column is fixedly connected to the middle of the top of the experimental rack. A multispectral detection camera is installed on both sides of the top of the column. Handrails are fixedly connected to both sides of the top of the cultivation trough, and a mesh frame is provided above the cultivation trough. A limiting component is fixedly connected to one side of the bottom of the mesh frame, and a fixed seat is slidably connected to the outer wall of the limiting component. The bottom of the fixed seat is fixedly connected to the top surface of the experimental rack.

[0006] The limiting component can be moved horizontally to remove it from the fixed base, which is used to quickly disassemble the grid frame for cleaning;

[0007] A drain pipe is installed on one side of the bottom of the cultivation tank, and a barrier pipe is slidably connected to the outer wall of the drain pipe. A drain outlet is opened on one side of the bottom of the barrier pipe. The barrier pipe can move vertically to remove the obstruction to the bottom opening of the drain pipe.

[0008] A support base is fixedly connected to the middle of the bottom of the experimental frame, and a base plate is slidably connected to the middle of the inner wall of the support base. The top two sides of the base plate are fixedly connected to the bottom of the barrier tube, and the base plate is used to drive the barrier tube to move vertically.

[0009] When the barrier tube moves downward, the drain pipe, the barrier tube and the drain outlet form a drainage channel, and the culture medium inside the culture tank is discharged through the drainage channel, thereby reducing the weight of the culture tank.

[0010] Preferably, the limiting member has a "T" shaped structure, the barrier tube has an "O" shaped structure, the support base has a "U" shaped structure, and the bottom end of the support base has an open movable cavity corresponding to the substrate.

[0011] By moving the space frame horizontally to disengage the bottom limiting piece from the fixed base, the space frame can be removed for cleaning.

[0012] Preferably, slide rails are slidably connected to both sides of the middle part of the substrate, and one side of the outer wall of the slide rail is fixedly connected to the inner wall of the support base. Springs are fixedly connected to both sides of the bottom end of the support base, and the top of the springs is fixedly connected to the bottom end of the substrate.

[0013] Pull the limiting seat so that its top slides along the base until the bottom of the limiting seat moves away from under the substrate. Then press the pedal with your foot to move the substrate down along the support base. The substrate will move the barrier tube down along the slide rail.

[0014] Preferably, the substrate, the slide rail and the spring form an elastic telescopic mechanism, and the substrate and the barrier tube have a "U" shaped structure.

[0015] The substrate is guided to move smoothly downwards by a slide rail. As the substrate moves downwards, it compresses the spring until the bottom of the barrier tube moves away from the bottom of the drain tube. Then, the limiting seat is pushed so that its bottom moves to the top of the substrate, thereby restricting the substrate and preventing the spring from returning and causing the substrate to move upwards.

[0016] Preferably, a base is fixedly connected to one side of the top of the support, and a limiting seat is slidably connected to the outer wall of the base. The base has a "U" shape and the limiting seat has an "L" shape.

[0017] The bottom of the limiting seat is located below the substrate, which restricts the substrate and prevents the substrate from moving the barrier tube downwards.

[0018] Preferably, the outer wall of the limiting seat is provided with pedals on both sides, and the top side of the pedal is fixedly connected to the base plate, and the pedal has an "L" shaped structure.

[0019] By pressing the pedal with your foot, the base plate moves down along the support seat.

[0020] As can be seen from the above, the multispectral detection device for identifying cucumber salt tolerance provided by this utility model has the following beneficial effects.

[0021] 1. The drainage can be easily opened by stepping on the pedal using the user's own weight, reducing the intensity of operation. After emptying the culture medium, the weight of the culture tank is greatly reduced. Combined with the handrail design, it is convenient for a single operator to carry and clean the culture tank. In addition, a limit seat is used for double locking to prevent accidental opening before drainage and to prevent resetting after drainage, thus improving safety.

[0022] 2. The space frame adopts a simple plug-in limiting structure, which can be quickly disassembled and assembled without tools, greatly facilitating daily cleaning work and helping to maintain a clean experimental environment. Attached Figure Description

[0032] 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.

[0033] Please see Figures 1-8 This utility model provides a technical solution: a multispectral detection device for identifying the salt tolerance of cucumber, including an experimental rack 1, a cultivation trough 2, a column 3 and a multispectral detection camera 4. The cultivation trough 2 is connected to both sides of the top of the experimental rack 1, and the column 3 is fixedly connected to the middle of the top of the experimental rack 1. The multispectral detection camera 4 is installed on both sides of the top of the column 3. Handrails 5 are fixedly connected to both sides of the top of the cultivation trough 2, and a mesh frame 6 is provided above the cultivation trough 2. A limiting member 7 is fixedly connected to one side of the bottom of the mesh frame 6, and a fixed seat 8 is slidably connected to the outer wall of the limiting member 7. The bottom of the fixed seat 8 is fixedly connected to the top surface of the experimental rack 1.

[0034] The limiting component 7 can be moved horizontally to remove the fixed base 8, which is used to quickly disassemble the grid frame 6 for cleaning;

[0035] A drain pipe 9 is installed on one side of the bottom of the cultivation tank 2, and a barrier pipe 10 is slidably connected to the outer wall of the drain pipe 9. A drain outlet 11 is opened on one side of the bottom of the barrier pipe 10. The barrier pipe 10 can move vertically to remove the obstruction to the bottom opening of the drain pipe 9.

[0036] A support base 12 is fixedly connected to the middle of the bottom of the experimental frame 1, and a base plate 13 is slidably connected to the middle of the inner wall of the support base 12. The top two sides of the base plate 13 are fixedly connected to the bottom of the barrier tube 10. The base plate 13 is used to drive the barrier tube 10 to move vertically.

[0037] The limiting member 7 has a "T" shaped structure, the blocking tube 10 has an "O" shaped structure, and the support base 12 has a "U" shaped structure. The bottom end of the support base 12 has an internal movable cavity corresponding to the substrate 13. The two sides of the middle part of the substrate 13 are slidably connected to the slide rail 14, and one side of the outer wall of the slide rail 14 is fixedly connected to the inner wall of the support base 12. The two sides of the bottom end of the support base 12 are fixedly connected to the spring 15, and the top of the spring 15 is fixedly connected to the bottom end of the substrate 13. The substrate 13, the slide rail 14 and the spring 15 form an elastic telescopic mechanism. The substrate 13 and the blocking tube 10 have a "U" shaped structure. The top side of the support base 12 is fixedly connected to the base 17, and the outer wall of the base 17 is slidably connected to the limiting seat 18. The base 17 has a "U" shaped structure, and the limiting seat 18 has an "L" shaped structure. The two sides of the outer wall of the limiting seat 18 are provided with pedals 16, and one side of the top of the pedals 16 is fixedly connected to the substrate 13. The pedals 16 have an "L" shaped structure.

[0038] In practice, the experimental rack 1 is first moved to the designated location in the laboratory. Then, the cucumber variety to be screened is identified. At this time, the two groups of cultivation tanks 2 are respectively the salt stress group and the control group. The control group is a nutrient solution, and the salt stress group is a NaCl solution prepared with the nutrient solution. The seedlings grow in sterile seedling trays in the cultivation tank 2. At this time, the light, temperature and humidity in the laboratory are constant until the cucumber vines grow upward along the net rack 6 and produce cucumbers.

[0039] At this time, the multispectral detection camera 4 at the top of column 3 is activated. Control group: Plant leaves, due to being filled with water and having a sponge-like cell structure, strongly reflect near-infrared light. Salt stress group: When plant leaves are subjected to salt stress, chlorophyll degrades, cell structure is damaged, and water is lost. Due to the reduction in chlorophyll, less red light is absorbed, which leads to an increase in reflectivity in the red light band. At this time, the spectroscopic system and image processor inside the multispectral detection camera 4 capture the spectral reflectance characteristics of the plant in a specific band to indirectly reflect the changes in its internal physiological and biochemical state, thereby determining the salt tolerance of the cucumber variety.

[0040] See Figure 1 , Figure 2 and Figure 8 In the initial state, the bottom of the limiting seat 18 is located below the substrate 13, which can effectively limit the displacement of the substrate 13 and prevent it from driving the barrier tube 10 to move downward.

[0041] When draining, first pull the limiting seat 18 outward so that its top slides along the base 17 until the bottom is completely detached from the base plate 13; then press the pedal 16 with your foot to drive the base plate 13 to move smoothly down along the support 12 and slide rail 14, simultaneously driving the barrier tube 10 down and compressing the spring 15; when the bottom of the barrier tube 10 moves down to detach from the drain pipe 9, immediately push the limiting seat 18 inward so that its bottom moves to the top of the base plate 13 and locks it, preventing the spring 15 from rebounding and causing the base plate 13 to move upward.

[0042] At this time, the drain pipe 9, the barrier pipe 10 and the drain outlet 11 together form a smooth drainage channel, and the culture medium in the culture tank 2 can be discharged smoothly, thereby significantly reducing the weight of the tank.

[0043] See Figure 2 and Figure 8 Move the space frame 6 horizontally so that the bottom limiting piece 7 is disengaged from the fixed base 8, and the space frame 6 can be removed for cleaning. Afterwards, simply insert the limiting piece 7 into the fixed base 8 to reinstall the space frame 6 back into its original position.

[0044] At this point, by grasping the handle 5 and moving it upwards to drain the nutrient solution from the culture tank 2, the operator can easily remove the culture tank 2 for thorough cleaning. Then, by stepping on the foot pedal 16, the operator can easily open the drainage using their own weight, reducing the intensity of operation. After draining the culture solution, the weight of the culture tank 2 is significantly reduced. Combined with the design of the handle 5, it is convenient for the operator to carry and clean the culture tank 2 by one person. Furthermore, the mesh frame 6 adopts a simple plug-in limiting structure, which can be quickly disassembled and assembled without tools, greatly facilitating daily cleaning work and thus helping to maintain a clean experimental environment.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
