Description

Technical Field

[0001] This invention belongs to the field of sugarcane cultivation technology, specifically a device for treating drought stress in sugarcane. Background Technology

[0002] Drought stress is an important factor to consider in sugarcane cultivation. To improve the drought resistance of sugarcane, researchers have been exploring various drought-resistant treatment methods. Among them, simulating the root growth environment under natural conditions to promote the healthy development of sugarcane roots is the key to improving its drought resistance. However, in actual operation, especially under indoor experimental conditions, the growth of sugarcane roots is often affected by physical barriers due to container limitations, resulting in abnormalities in its spatial distribution, anatomical structure, and water absorption dynamics.

[0003] Although existing devices for treating drought stress in sugarcane can simulate drought environments to some extent, they still have significant drawbacks. First, due to the physical barrier formed by the container wall, the lateral roots of sugarcane are forced to coil horizontally along the inner wall of the container. This not only leads to an artificially high root length density in the near-wall area, reaching 2-3 times the natural value, but also causes the root tip meristem to generate mechanical stress signals upon contact with the hard container wall, triggering an obstacle avoidance response with a root tip turning angle greater than 45°, which seriously affects the normal growth and development of the root system. Second, the roots in continuous contact with the container wall will exhibit abnormal lignification, accelerating lignin deposition and forming ultra-thick cell walls, resulting in decreased hydraulic conductivity and obstructed material transport. In addition, the low-permeability zone formed at the interface between the container wall and the soil forces water to preferentially flow vertically along the center of the container, causing a shift in water absorption depth and failure of hydraulic lifting. At the same time, the "pseudo-root-soil interface" formed at the contact surface between the root system and the container wall increases the contact pressure, leading to distorted water absorption rates, delayed water absorption, and abnormal nighttime refilling. Therefore, improvements and optimizations are needed. Summary of the Invention

[0006] The obstacle avoidance mechanism includes a drive component and an obstacle avoidance component. The obstacle avoidance component includes a threaded groove formed on the inner wall of the planting cylinder.

The plurality of cylinders are designed in a circular shape, and a plurality of stirring rods are fixedly installed on the outer wall of the plurality of cylinders. The plurality of stirring rods are designed in a U-shape and their opening direction is fixedly connected to the cylinder.

[0010] Preferably, a cylindrical block is rotatably fitted on the outer wall of the planting cylinder, and an annular groove is formed on the top of the cylindrical block. A filling groove is fixedly installed on the outer wall of the cylindrical block, and the filling groove is connected to the annular groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention provides a clear growth guide for sugarcane roots by setting up an obstacle avoidance mechanism through the design of threaded grooves and cylindrical grooves on the inner wall of the planting cylinder. This design not only guides the roots to grow downward along the threaded grooves, but also effectively avoids the problem of horizontal coiling of the roots. By driving the planting cylinder to rotate through a motor, the teeth and gear transmission system in the obstacle avoidance mechanism work together to achieve effective management of the growth of sugarcane lateral roots. The rotation of the planting cylinder prevents the lateral roots from extending outward and contacting the inner wall to coil horizontally, thereby avoiding the problems of growth restriction and uneven nutrient absorption caused by root coiling. This allows for the accurate acquisition of relevant index data on sugarcane drought resistance under different water stress conditions, as well as the drought resistance performance of different sugarcane varieties.

[0018] 2. By setting threaded grooves, the present invention allows excess water to flow downwards along the threaded grooves on the outer wall of the planting cylinder, which can not only avoid regional water shortages, but also allow excess water to be filtered by the filter screen and collected into the collection box, realizing the recycling of irrigation liquid and avoiding the waste of water resources.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 11 As shown, the present invention provides a device for treating drought stress in sugarcane, including a base frame 1, an installation chamber 2 fixedly installed on the inner wall of the base frame 1, a planting cylinder 3 rotatably installed on the top of the installation chamber 2, the planting cylinder 3 is divided into four sections and each section is four meters long, and adopts a high-strength aluminum alloy sleeve structure design, an obstacle avoidance mechanism is provided on the inner wall of the planting cylinder 3, and a stirring mechanism is provided on the outer wall of the planting cylinder 3.

[0033] The obstacle avoidance mechanism includes a drive component and an obstacle avoidance component. The obstacle avoidance component includes a threaded groove 301 formed on the inner wall of the planting cylinder 3. An annular groove 302 is formed on the top of the planting cylinder 3. Several cylindrical grooves 3021 are formed at the bottom of the annular groove 302. The several cylindrical grooves 3021 are arranged in a circumferential array. The several cylindrical grooves 3021 penetrate the planting cylinder 3 and are connected to the threaded groove 301. A root guide tube 5 is fixedly installed inside the planting cylinder 3. The top of the root guide tube 5 is lower than the top of the planting cylinder 3. The root guide tube 5 is composed of several identical cylindrical tubes. A filter screen 12 is fixedly installed at the bottom of the planting cylinder 3. A collection box 13 is set below the filter screen 12.

[0034] The above solution involves setting threaded grooves 301 and cylindrical grooves 3021 on the inner wall of the planting cylinder 3, which not only provides growth guidance for the sugarcane roots but also avoids the problem of horizontal coiling of the roots. At the same time, the rotation of the planting cylinder 3 further promotes the uniform distribution and growth of the sugarcane roots. The auxiliary cooperation between the root guide tube 5 and the irrigation system ensures that the irrigation liquid can flow smoothly into the interior of the planting cylinder 3, providing sufficient water and nutrients for the sugarcane roots. The design of its top being lower than the top of the planting cylinder 3 avoids waste caused by liquid overflow.

[0035] like Figures 1 to 4 As shown, the drive mechanism includes several teeth 4 fixedly installed on the outer wall of the planting cylinder 3. A rotating rod 11 is rotatably installed on the top of the installation chamber 2. Gear 2 1101 and gear 3 1102 are fixedly sleeved on the outer wall of the rotating rod 11. Gear 3 1102 is located above gear 2 1101. Gear 2 1101 meshes with the teeth 4. A motor 10 is fixedly installed on the top of the installation chamber 2. Gear 1 1001 is fixedly sleeved on the output shaft of the motor 10. Gear 1 1001 meshes with gear 3 1102.

[0036] The above scheme is adopted as follows: by starting the motor 10, the output shaft of the motor 10 drives the gear 1001 to rotate. The meshing of the gear 1001 and the gear 3 1102 drives the rotating rod 11 and the gear 2 1101 to rotate. The meshing of the gear 2 1101 and the tooth 4 drives the planting cylinder 3 to rotate, thus preventing the sugarcane's lateral roots from extending outward and contacting the inner wall of the planting cylinder 3 and coiling horizontally during the production process. The rotation of the planting cylinder 3 drives the fixing ring 6 to rotate together, so that the fixing ring 6 drives several cylinders 601 and the stirring rod 602 to rotate together, which fully stirs the liquid in the annular groove 701, ensuring the uniform distribution of nutrients. At the same time, the rotation of the planting cylinder 3 can also prevent the sugarcane's lateral roots from extending outward and contacting the inner wall and coiling horizontally. Excess water will flow downward with the threaded groove 301 on the outer wall of the planting cylinder 3 and finally flow into the collection box 13 after being filtered by the filter screen 12. The rotation of the planting cylinder 3 will not interfere with this collection process, but will help the uniform distribution and rapid discharge of water.

[0037] like Figures 9 to 11As shown, the mixing mechanism includes a fixing ring 6 fixedly installed on the outer wall of the top of the planting cylinder 3. Several cylinders 601 are fixedly installed at the bottom of the fixing ring 6. These cylinders 601 are circumferentially designed, and several mixing rods 602 are fixedly installed on the outer walls of each cylinder 601. The mixing rods 602 are U-shaped and their openings are fixedly connected to the cylinders 601. A cylindrical block 7 is rotatably fitted onto the outer wall of the planting cylinder 3. An annular groove 701 is formed at the top of the cylindrical block 7. A feeding trough 7011 is fixedly installed on the outer wall of the cylindrical block 7, and the feeding trough 7011 is connected to the annular groove 701. The cylinders 601 and the mixing rods 602 are all located inside the annular groove 701, and the cylinders 601 are rotatably connected to the annular groove 701. A water pump controller 8 is installed on the outside of the 7. Hollow tubes 9 are fixedly installed on both sides of the water pump controller 8. The hollow tube 9 near the cylindrical block 7 extends into the annular groove 701 and is fixedly connected to the cylindrical block 7. An annular tube 901 is fixedly installed at the top of another hollow tube 9. Several straight tubes 9011 and 9012 are fixedly installed at the bottom of the annular tube 901. The straight tubes 9011 and 9012 are all inclined and in opposite directions. The bottom ends of the straight tubes 9011 are bent and are perpendicular to the bottom surface of the annular groove 302. Two F-type brackets 101 are fixedly installed on the top of the base frame 1. Both F-type brackets 101 are fixedly connected to the cylindrical block 7. The tops of both F-type brackets 101 are rotatably connected to the fixing ring 6.

[0038] The above scheme is adopted: By setting up a cylindrical block 7, an annular groove 701 opened at the top of the cylindrical block 7 serves as a storage and initial distribution area for irrigation liquid. Through the connection with the feeding trough 7011, users can easily add water or nutrient solution to the annular groove 701 through the feeding trough 7011 without disassembling any parts, which greatly simplifies the operation process. By setting up several cylinders 601 and stirring rods 602 inside the annular groove 701, the fixed ring 6 rotates with the planting cylinder 3, which plays a role in fully stirring the irrigation liquid, ensuring that the nutrients in the liquid can be evenly distributed, and avoiding sedimentation or stratification caused by long-term standing. This ensures that all parts of the sugarcane root system can obtain a balanced supply of nutrients, so that the sugarcane can grow normally, and accurately obtain relevant index data of sugarcane drought resistance under different water stress conditions.

[0039] By activating the water pump controller 8, the two hollow pipes 9 efficiently transport the liquid from the annular groove 701 to the annular pipe 901. Precise irrigation is then achieved through the inclined straight pipes 9011 and 9012. The bottom of straight pipe 9011 is bent and perpendicular to the bottom surface of the annular groove 302, allowing water to flow better into the annular groove 302 without affecting the rotation of the planting cylinder 3. Straight pipe 9012 directly sprays water onto the sugarcane roots. When the cylinder rotates, it not only drives the cylindrical block 7 and its internal stirring system to rotate, but also achieves continuous stirring of the liquid in the annular groove 701 through the connection of the fixing ring 6 with the cylinder 601 and the stirring rod 602, ensuring the uniformity of the irrigation liquid. Excess water will flow downwards through the threaded groove 301 on the outer wall of the planting cylinder 3, and finally flow into the collection box 13 after being filtered by the filter screen 12. This not only effectively avoids the waste of water resources, but also realizes the recycling of irrigation liquid and further improves the utilization rate of resources.

[0040] Working principle and usage process of this invention:

[0041] First, fill the planting tube 3 with soil. Plant the sugarcane in the planting tube 3, ensuring that the sugarcane is in the middle of the ring tube 901 to achieve central positioning. Central positioning ensures that water is supplied evenly around the sugarcane roots, effectively preventing the sugarcane from growing off-center.

[0042] Water or nutrient solution is injected into the second annular trough 701 through the feeding trough 7011. The water pump controller 8 is activated, and the liquid in the second annular trough 701 is drawn into the annular pipe 901 through two hollow pipes 9. The liquid is discharged into the first annular trough 302 through the first straight pipe 9011 and transferred downward through the cylindrical trough 3021 to ensure that the bottom soil obtains water. The second straight pipe 9012 directly sprays water to the sugarcane roots, realizing precise irrigation and nutrient solution supply. This ensures that all parts of the sugarcane root system can obtain sufficient water and nutrients, and the bottom soil can also obtain water, preventing growth problems caused by uneven water distribution.

[0043] By setting up root canal 5, the sugarcane taproot is guided to grow downwards, ensuring that the sugarcane taproot grows deep;

[0044] Start motor 10, drive planting cylinder 3 to rotate through gear transmission. The rotation of planting cylinder 3 prevents sugarcane lateral roots from extending outward and contacting the inner wall to coil horizontally, effectively managing the growth of sugarcane lateral roots and preventing growth restriction and uneven nutrient absorption caused by horizontal coiling.

[0045] The rotation of the planting cylinder 3 causes the fixing ring 6 to rotate together, which in turn causes the cylinder 601 and the stirring rod 602 to rotate. The stirring rod 602 fully stirs the liquid in the annular groove 701 to ensure that nutrients are evenly distributed, improve the uniformity of water or nutrient solution, and ensure that all parts of the sugarcane can receive a balanced supply of nutrients.

[0046] Excess water flows downwards along the threads of the threaded groove 301. After being filtered by the filter screen 12, the water flows into the collection box 13, achieving effective collection and filtration of excess water, preventing water waste and environmental pollution. The collection box 13 can be used for subsequent irrigation or discharge treatment, improving resource utilization.
