Description

Technical Field

[0001] This invention relates to the field of kudzu stem cutting propagation technology, specifically to a device for precise administration of kudzu stem cutting regulator. Background Technology

[0002] Kudzu is a legume with high medicinal and ecological value. Its rhizome can be used as medicine and is rich in various active ingredients such as puerarin. It is widely used in the fields of medicine and food. Due to the problems of low germination rate and long growth cycle of kudzu seed propagation, stem cutting has become the main method of large-scale seedling cultivation. In the process of kudzu stem cutting, in order to promote rapid rooting of stem segments and improve the survival rate of cuttings, it is usually necessary to soak the end of the stem segment away from the bud with a regulator before cutting. The regulator stimulates the cell division and differentiation of the stem segment base to form roots. According to the article "Propagation of Kudzu in Shan Geng Tan: Cutting Propagation", in current production practices, the soaking of wild kudzu stem segments mostly relies on simple plastic containers. For example, farmers often use plastic basins or buckets as soaking devices. These soaking devices generally consist of a tank and a cover. The tank is made of plastic and has a certain capacity to hold an appropriate amount of regulator solution. The cover can reduce solution evaporation. When using this soaking container, the operator puts the wild kudzu stem segments into the tank, immersing the base of the stem segments in the regulator solution. After a certain period of time, the stem segments are removed to complete the soaking process. In the actual process of soaking kudzu stem segments in plastic basins or buckets, the stem segments are long and thin, and lack effective fixing devices after being placed in the tank. During the soaking process, the stem segments easily slide in the solution, and the end that is originally away from the bud may shift, causing the bud to accidentally slide into the soaking solution. The regulator solution usually contains a high concentration of hormone components. When the bud comes into contact with these solutions, it may be overstimulated, affecting its normal germination and growth, and in severe cases, it may even cause bud necrosis, reducing the survival rate after cutting and causing unnecessary losses in seedling cultivation. At the same time, the sliding of the stem segments may also cause some stem segments to not be fully soaked in the regulator solution, affecting the effectiveness of the regulator, further reducing the rooting rate and seedling quality.

[0003] Therefore, this invention proposes a device for precise administration of kudzu stem cutting regulator to solve the above problems. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a precise dosing device for kudzu stem cutting growth regulator. Through positioning holes and silicone nozzles on a fixed basket, the kudzu stem cuttings are precisely fixed, ensuring that only the base is immersed in the regulator solution to prevent bud damage. Simultaneously, it guarantees a consistent immersion depth for the stem cuttings, improving the stability of seedling quality and solving the problems of easy stem slippage, bud damage, and uneven immersion in traditional soaking devices.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A device for precise administration of a kudzu stem cutting regulator, comprising an soaking tank, a fixed basket provided in the soaking tank, the height of the fixed basket being set to 2 / 3 of the height of the soaking tank, the outer wall of the fixed basket slidingly engaging with the inner wall of the soaking tank, symmetrically arranged support plates fixedly connected to the top of the fixed basket, the bottom of the support plates contacting the top of the soaking tank, a plurality of positioning holes opened in the bottom wall of the fixed basket, a plurality of silicone fixing nozzles corresponding to the positioning holes fixedly connected to the bottom of the fixed basket, and symmetrically arranged control components on the soaking tank for controlling the lifting of the fixed basket to drive the stem cuttings in the fixed basket to be lifted to drain water.

[0006] The technical principle of the above solution is as follows: The bottom of the support plate on the fixed basket contacts the top of the soaking tank. The weight of the fixed basket itself is transferred to the top of the soaking tank through the support plate, forming a stable support. The end of the kudzu stem segment away from the bud is passed through the positioning hole on the fixed basket and inserted into the silicone fixing nozzle. The elastic deformation of the silicone fixing nozzle generates a clamping force to fix the stem segment, ensuring that the base of the stem segment extends out of the bottom of the fixed basket. A regulator solution is injected into the soaking tank, and the solution height does not exceed the height of the fixed basket. At this time, the base of the stem segment is immersed in the solution, and the bud is located in the fixed basket, avoiding contact with the solution. When the soaking time reaches the preset time, an external force is applied by the control component, which drives the fixed basket to slide upward along the inner wall of the soaking tank. The fixed basket drives the stem segment to rise synchronously. When the base of the stem segment leaves the solution surface, the water begins to drain. After draining, the stem segment can be taken out for cutting.

[0007] The above approach has the following beneficial effects: 1. This method uses positioning holes and silicone fixing nozzles to precisely fix the kudzu stem segments, ensuring that only the base is immersed in the regulator solution, avoiding damage to the buds from contact with high concentrations of regulator, and effectively improving the survival rate of cuttings; 2. In this solution, the control component can quickly lift the fixing basket, allowing the base of the stem segment to leave the solution and drain naturally, reducing the waste of regulators and preventing the stem segment from carrying too much solution, which would cause the cutting substrate to become too wet. 3. This scheme uses a uniform spacing between positioning holes and a standardized silicone fixing nozzle to ensure that the soaking depth of each stem segment is consistent, so that the regulator works evenly, improving the stability of seedling quality and avoiding uneven rooting rates caused by differences in manual operation.

[0008] Furthermore, each control component includes a rotating column, which is rotatably connected to the middle of the corresponding support plate. The rotating column is set along the height direction of the soaking tank and passes through the side wall of the soaking tank. The side wall of the soaking tank is symmetrically opened with a limit groove about the axis of the rotating column. A slider is slidably fitted in the limit groove. The slider is fixedly connected to the rotating column. A handle is fixedly connected to the top of the rotating column.

[0009] Beneficial effects: The operator pulls the handle upwards to move the rotating column upwards, which in turn moves the support plate and the fixed basket upwards. When the rotating column moves upwards until the slider disengages from the limiting groove, the operator rotates the rotating column to misalign the slider with the corresponding limiting groove inlet. At this point, the bottom of the slider is in contact with the top of the soaking tank, causing the fixed basket to lift the stem segments synchronously and maintain the height after lifting, separating the stem segments from the liquid in the soaking tank and draining them. After draining, the stem segments are removed for cutting. After draining, the operator rotates the rotating rod by hand to rotate the slider to align with the limiting groove inlet and releases the handle. The support force of the top of the soaking tank on the slider disappears, and the slider descends along the limiting groove due to gravity, causing the fixed basket to descend and reset synchronously. By precisely controlling the lifting height of the fixed basket, the operator can flexibly adjust the soaking depth and draining time according to the soaking requirements.

[0010] Furthermore, a drain channel is provided on the side wall of the soaking tank near the bottom wall of the soaking tank, located below one of the rotating columns. The diameter of the drain channel is less than or equal to the width of the rotating column.

[0011] Beneficial effects: After soaking, when the fixed basket is lifted by the rotating column to drain the stem segments, the rotating column moves upward to separate the rotating column from the drainage channel. At this time, the drainage channel is connected to the outside, and the waste liquid is discharged through the drainage channel. The waste liquid can be discharged without emptying the soaking tank. When processing multiple batches of stem segments continuously, the old regulator solution can be quickly discharged and a new solution can be injected, which improves the continuity of seedling cultivation.

[0012] Furthermore, the side wall of the soaking tank is connected to a drug delivery channel.

[0013] Beneficial effects: The conditioning solution is injected into the soaking tank through the drug delivery channel, and the solution flows into the soaking tank along the drug delivery channel under the action of gravity.

[0014] Furthermore, the top of the drug delivery channel is designed as a funnel structure.

[0015] Beneficial effects: The funnel structure increases the inlet area of ​​the drug delivery channel by guiding the flow, making it easier for operators to quickly and accurately inject the regulator solution and reducing solution spillage.

[0016] Furthermore, all silicone fixing nozzles are designed with an inverted trapezoidal structure.

[0017] Beneficial effects: By utilizing the inverted trapezoidal structure combined with the elastic deformation properties of silicone, it is possible to achieve adaptive clamping and fixation of kudzu stem segments of different thicknesses, while facilitating the insertion and removal of stem segments.

[0018] Furthermore, the bottom wall of the soaking tank is designed with an inclined structure, and the side of the bottom wall closest to the drug delivery channel is lower than the other side.

[0019] Beneficial effects: After soaking, open the drain channel. Under the action of gravity, the solution flows along the inclined inner bottom wall to the drain channel and is eventually discharged through the drain channel, reducing the amount of solution residue in the soaking tank.

[0020] Furthermore, the sidewalls of the soaking tank are designed to be transparent.

[0021] Beneficial effects: The transparent structure allows operators to directly observe the solution level in the soaking tank, the soaking status of the stem segments, and the position of the fixing basket, facilitating real-time monitoring and operational adjustments.

[0022] Furthermore, silicone pads are fixedly connected to the bottom of each rotating column.

[0023] Beneficial effects: By utilizing the elastic deformation properties of silicone, the impact force between the rotating column and the bottom wall of the soaking tank during the descent is absorbed, while avoiding direct contact between the rotating column and the bottom wall of the soaking tank, thus reducing wear.

[0024] Furthermore, a liquid level sensor is fixedly connected to the side wall of the soaking tank, and the liquid level sensor is electrically connected to a controller. The controller is embedded in the side wall of the soaking tank, and a display is embedded in the side wall of the soaking tank. The display is electrically connected to the controller.

[0025] Beneficial effects: The liquid level sensor detects the height of the solution in the soaking tank in real time, converts the liquid level signal into an electrical signal and transmits it to the controller. The controller receives the electrical signal from the liquid level sensor, analyzes and processes it, and then sends the liquid level information to the display. The operator can intuitively understand the solution height through the display, enabling the operator to accurately control the amount of regulator solution injected to ensure that the solution height meets the soaking requirements and avoid solution waste or insufficient soaking.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The following detailed description illustrates the specific implementation method: Example 1:

[0032] As attached Figure 1As shown: A device for precise administration of regulators for kudzu stem cuttings includes a soaking tank 1. Since the kudzu stems are long and narrow, and there is no fixing device during the soaking process, the stems are prone to sliding in the solution. This causes the buds of the stems to slide into the soaking solution. When the buds come into contact with these solutions, they may be overstimulated, affecting their normal germination and growth. In severe cases, it may even lead to bud necrosis, reducing the survival rate after cutting. At the same time, the sliding of the stems causes the base of some stems to not be fully soaked in the regulator solution, affecting the effect of the regulator and further reducing the rooting rate and seedling quality. To ensure the regulator is applied precisely to the side of the kudzu cutting away from the bud to improve rooting rate, please refer to the attached... Figure 2 As shown, a fixed basket 2 is provided in the soaking tank 1. The height of the fixed basket 2 is set to 2 / 3 of the height of the soaking tank 1. The outer side wall of the fixed basket 2 is slidably fitted with the inner side wall of the soaking tank 1. The top of the fixed basket 2 is fixedly connected to a symmetrically arranged support plate 3 by bolts. The bottom of the support plate 3 is in contact with the top of the soaking tank 1. Several positioning holes 4 are opened on the bottom wall of the fixed basket 2. Several silicone fixing nozzles 5 corresponding to the positioning holes 4 are glued to the bottom of the fixed basket 2. The silicone fixing nozzles 5 are all set as inverted trapezoidal structures. The soaking tank 1 is symmetrically provided with control components for controlling the lifting of the fixed basket 2 to drive the stem segments in the fixed basket 2 to lift and drain water. As attached Figure 2 Appendix Figure 3 and attached Figure 6 As shown, the control components all include a rotating column 6, which is rotatably connected to the middle of the corresponding support plate 3. The rotating column 6 is set along the height direction of the soaking tank 1 and passes through the side wall of the soaking tank 1. The side wall of the soaking tank 1 is symmetrically opened with a limit groove 7 about the axis of the rotating column 6. A slider 8 is slidably fitted in the limit groove 7. The slider 8 is fixedly connected to the rotating column 6 by bolts. A handle 9 is fixedly connected to the top of the rotating column 6 by bolts. A silicone pad is glued to the bottom of the rotating column 6. As attached Figure 4 As shown, a drain channel 10 is located below one of the rotating columns 6 on the side wall of the soaking tank 1 near the bottom wall of the soaking tank 1. The diameter of the drain channel 10 is less than or equal to the width of the rotating column 6 (initially, the bottom end of the rotating column 6 is located inside the drain channel 10, preventing the drain channel 10 from communicating with the outside; at this time, the drain channel 10 is closed); as shown in the attached figure. Figure 5 As shown, the side wall of the soaking tank 1 is connected to the drug delivery channel 11, and the top of the drug delivery channel 11 is set as a funnel structure; the bottom wall of the soaking tank 1 is set as an inclined structure, and the side of the bottom wall of the soaking tank 1 closest to the drug delivery channel 11 is lower than the other side. The specific implementation process is as follows: When administering the regulator to the kudzu stem cuttings, first, pass the end of the kudzu stem cutting away from the bud through the positioning hole 4 on the bottom wall of the fixing basket 2, and insert it into the inverted trapezoidal silicone fixing nozzle 5 corresponding to the positioning hole 4. The elastic deformation characteristics and inverted trapezoidal structure of the silicone fixing nozzle 5 can adapt to kudzu stem cuttings of different thicknesses. The silicone fixing nozzle 5 itself generates clamping force to fix the stem cutting, ensuring that the base of each stem cutting extends out of the bottom of the fixing basket 2, while the bud remains inside the fixing basket 2. This avoids the problem of the stem cutting sliding during the soaking process, which could cause the bud to be damaged by contact with the regulator solution and insufficient soaking of the base. It precisely controls the regulator to act only on the base of the stem cutting, avoiding excessive stimulation of the bud by high concentrations of regulator, and providing a guarantee for the normal germination and growth of the bud. At the same time, the uniform spacing of the positioning holes 4 and the specifications of the silicone fixing nozzle 5 can ensure that the soaking depth of each stem cutting is consistent, making the regulator effect uniform and improving the stability of seedling quality. Before soaking, the conditioner solution is precisely prepared: sodium indolebutyrate and sodium naphthaleneacetate are mixed in a 3:1 mass ratio as the core rooting components. 300 mg of sodium indolebutyrate and 100 mg of sodium naphthaleneacetate are accurately weighed, completely dissolved in a small amount of 95% ethanol, and then diluted to 1 L with distilled water to obtain a conditioner stock solution with a concentration of 400 mg / L. Before use, the stock solution is diluted with distilled water at a 1:2 volume ratio to obtain a final cutting soaking working solution with a concentration of 200 mg / L. Next, the cutting soaking working solution is injected through the administration channel 11 on the side wall of the soaking tank 1. The funnel structure increases the inlet area of ​​the administration channel 11, facilitating quick and accurate injection by the operator and reducing spillage. The solution flows into the soaking tank along the administration channel 11 under gravity. In soaking tank 1, the injection stops when the solution level reaches 1 / 3 of the tank's height. Based on the design capacity of fixed basket 2, when soaking 100 kudzu stem segments at a time, the amount of working solution injected is 120mL. The amount of regulator absorbed by a single stem segment is controlled between 0.8-1.2mL. This ensures that the base of all stem segments is completely submerged while preventing the solution from contacting the buds in fixed basket 2, thus achieving a precise match between the dosage and the number of stem segments. At this point, the base of the stem segments located below fixed basket 2 is completely submerged in the regulator solution, while no solution enters the fixed basket 2 where the buds are located, effectively isolating the buds from the regulator solution. The height of fixed basket 2 is set to 2 / 3 of the height of soaking tank 1, ensuring sufficient soaking depth for the base of the stem segments while preventing excessive solution from overflowing from soaking tank 1. During the soaking process, the temperature is controlled at 20-25℃, and direct sunlight is avoided. The soaking time is set to 12-15 minutes to ensure that the regulator is fully absorbed by the base of the stem segment. When the soaking time reaches the preset requirement, the operator holds the handle 9 at the top of the rotating column 6 and pulls it upward. The rotating column 6 moves upward accordingly. Since the rotating column 6 is rotatably connected to the middle of the corresponding support plate 3, and the slider 8 on the rotating column 6 slides with the limiting groove 7, the upward movement of the rotating column 6 will drive the support plate 3 to rise synchronously, thereby driving the fixed basket 2 to slide upward along the inner wall of the soaking tank 1. The fixed basket 2 drives the kudzu stem segments inside to rise together. When the rotating column 6 moves upward until the slider 8 is disengaged from the limiting groove 7, the operator turns the handle 9 to drive the rotating column 6 to rotate, so that the slider 8 is misaligned with the entrance of the corresponding limiting groove 7. At this time, the bottom of the slider 8 contacts the top of the soaking tank 1, and the top of the soaking tank 1 supports the slider 8, keeping the fixed basket 2 at the height after being lifted, so that the base of the stem segment leaves the solution surface and begins to drain water. When the rotating column 6 moves upward, the rotating column 6 is offset from the drainage channel 10, and the drainage channel 10 is connected to the outside. Under the action of gravity, the waste liquid in the soaking tank 1 flows along the inclined inner bottom wall to the side of the drainage channel 10 and is finally discharged through the drainage channel 10. The waste liquid can be discharged without emptying the soaking tank 1. When processing multiple batches of stem segments, the old regulator solution can be quickly discharged and a new solution can be injected, which improves the continuity and efficiency of seedling cultivation. After draining, the operator rotates handle 9 again to align slider 8 with the inlet of limiting groove 7, and then releases handle 9. The supporting force of the top of soaking tank 1 on slider 8 disappears, and under its own weight, fixed basket 2 and rotating column 6 drive slider 8 to descend along limiting groove 7. Fixed basket 2 then returns to the soaking tank 1. The silicone pad fixedly connected to the bottom of rotating column 6 can absorb the impact force when rotating column 6 contacts the bottom wall of soaking tank 1 during the descent of rotating column 6, avoiding direct contact between rotating column 6 and bottom wall of soaking tank 1 and causing wear, thus extending the service life of the device.

[0033] Example 2:

[0034] As attached Figure 1As shown, the difference from Embodiment 1 is that a liquid level sensor is fixedly connected to the side wall of the soaking tank 1. The preferred model of the liquid level sensor is Turck Uprox+ UM30. The liquid level sensor is electrically connected to a controller, which is preferably an Arduino Nano. The controller is embedded in the side wall of the soaking tank 1, and a display is embedded in the side wall of the soaking tank 1. The preferred model of the display is an OLED SSD1306 display screen. The display is electrically connected to the controller. The liquid level sensor monitors the height of the solution in the soaking tank 1 in real time and converts the liquid level signal into an electrical signal, which is then transmitted to the controller. The controller sends the analyzed and processed liquid level signal to the display. The operator can intuitively understand the solution height through the display, enabling the operator to accurately control the amount of regulator solution injected, thus avoiding solution waste or insufficient soaking.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
