Description

Technical Field

[0001] The present invention belongs to the technical field of sugarcane cultivation, and specifically relates to a device for drought stress treatment of sugarcane. Background Art

[0002] During the process of sugarcane cultivation, drought stress is an important consideration factor. In order to improve the drought resistance of sugarcane, scientific researchers have continuously explored various drought 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 performance. However, in actual operation, especially under indoor experimental conditions, due to container limitations, the growth of sugarcane roots is often affected by physical barriers, resulting in abnormalities in aspects such as their spatial distribution, anatomical structure, and water absorption kinetics.

[0003] Although the existing devices for drought stress treatment of sugarcane can simulate the drought environment to a certain extent, they still have significant drawbacks. First of all, due to the formation of a physical barrier by the container wall, the lateral roots of sugarcane are forced to horizontally coil along the inner wall of the container. This not only leads to a falsely high root length density in the near-wall area, reaching 2 - 3 times the natural value, but also causes mechanical stress signals to be generated after the root tip meristem region contacts the hard barrel wall, triggering an obstacle avoidance reaction, with the root tip turning angle being greater than 45°, seriously affecting the normal growth and development of the roots. Secondly, the roots continuously in contact with the barrel wall will show abnormal lignification, accelerating lignin deposition and forming an ultra-thick cell wall, resulting in a decrease in hydraulic conductivity and obstruction of 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 the water absorption depth to shift and the hydraulic lift to fail. At the same time, the "pseudo root-soil interface" formed at the contact surface between the roots and the barrel wall increases the contact pressure, leading to distorted water absorption rate, water absorption lag, and abnormal nocturnal replenishment. Therefore, it is necessary to improve and optimize it. Summary of the Invention

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 to 11 shown, the present invention provides a device for drought stress treatment of sugarcane, including a chassis 1, an installation bin 2 is fixedly installed on the inner wall of the chassis 1, a planting cylinder 3 is rotatably installed on the top of the installation bin 2, the planting cylinder 3 is divided into four sections and each section is four meters long, and a high-strength aluminum alloy sleeve structure design is adopted. Obstacle avoidance mechanisms are respectively arranged on the inner wall of the planting cylinder 3, and a stirring mechanism is arranged on the outer wall of the planting cylinder 3;

[0033] The obstacle avoidance mechanism includes a driving component and an obstacle avoidance component. The obstacle avoidance component includes a thread groove 301 opened on the inner wall of the planting cylinder 3. An annular groove 302 is opened at the top of the planting cylinder 3. A plurality of cylindrical grooves 3021 are opened at the bottom of the annular groove 302. The plurality of cylindrical grooves 3021 are arranged in a circumferential array design. The plurality of cylindrical grooves 3021 penetrate through the planting cylinder 3 and are communicated with the thread groove 301. A guide root tube 5 is fixedly installed inside the planting cylinder 3. The top of the guide root tube 5 is lower than the top of the planting cylinder 3. The guide root tube 5 is composed of a plurality of identical cylindrical tubes. A filter screen 12 is fixedly installed at the bottom of the planting cylinder 3, and a collection box 13 is arranged below the filter screen 12.

[0034] Adopting the above - mentioned solution: By setting the thread groove 301 and the cylindrical groove 3021 on the inner wall of the planting cylinder 3, it not only provides a growth guide 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 guide pipe 5 and the irrigation system: The design of the guide pipe 5 ensures that the irrigation liquid can smoothly flow into the interior of the planting cylinder 3, providing sufficient water and nutrients for the sugarcane roots. The design that its top is lower than the top of the planting cylinder 3 avoids the waste caused by liquid overflow.

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

[0036] Adopting the above - mentioned solution: By starting the motor 10, the output shaft of the motor 10 drives the first gear 1001 to rotate. Through the meshing of the first gear 1001 and the third gear 1102, the rotating rod 11 and the second gear 1101 are driven to rotate. Through the meshing of the second gear 1101 and the teeth 4, the planting cylinder 3 is driven to rotate, avoiding the horizontal coiling of the secondary roots of the sugarcane in the production process when they extend outward and contact the inner wall of the planting cylinder 3. By the rotation of the planting cylinder 3, the fixed ring 6 is driven to rotate together, so that the fixed ring 6 drives several cylinders 601 and stirring rods 602 to rotate together, fully stirring the liquid in the second annular groove 701 to ensure the uniform distribution of nutrients. At the same time, the rotation of the planting cylinder 3 can also avoid the problem of horizontal coiling of the secondary roots of the sugarcane when they extend outward and contact the inner wall. The excess water will flow downward along the thread 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 does not interfere with this collection process, but instead helps the uniform distribution and rapid discharge of water.

[0037] As Figures 9 to 11As shown in the figure, the stirring mechanism includes a fixed ring 6 fixedly installed on the outer wall of the top of the planting cylinder 3. A plurality of cylinders 601 are fixedly installed at the bottom of the fixed ring 6. The plurality of cylinders 601 are circumferentially designed. A plurality of stirring rods 602 are fixedly installed on the outer walls of the plurality of cylinders 601. The plurality of stirring rods 602 are designed in a U shape and the opening directions are fixedly connected to the cylinders 601. A cylinder block 7 is rotatably sleeved on the outer wall of the planting cylinder 3. An annular groove two 701 is opened at the top of the cylinder block 7. A feeding groove 7011 is fixedly installed on the outer wall of the cylinder block 7. The feeding groove 7011 communicates with the annular groove two 701. The plurality of cylinders 601 and the stirring rods 602 are both located inside the annular groove two 701. The plurality of cylinders 601 are rotatably connected to the annular groove two 701. A water pump controller 8 is arranged outside the cylinder block 7. Hollow tubes 9 are fixedly installed on both sides of the water pump controller 8. The hollow tube 9 close to the cylinder block 7 extends into the annular groove two 701 and is fixedly connected to the cylinder block 7. The top of the other hollow tube 9 is fixedly installed with an annular tube 901. A plurality of straight tubes one 9011 and straight tubes two 9012 are fixedly installed at the bottom of the annular tube 901. The plurality of straight tubes one 9011 and the straight tubes two 9012 are both designed to be inclined and the inclined directions are opposite. The bottom ends of the plurality of straight tubes one 9011 are bent and are perpendicular to the bottom surface of the annular groove one 302. Two F-shaped brackets 101 are fixedly installed on the top of the chassis 1. Both of the two F-shaped brackets 101 are fixedly connected to the cylinder block 7. The tops of the two F-shaped brackets 101 are rotatably connected to the fixed ring 6.

[0038] Adopting the above scheme: By setting the cylinder block 7, the annular groove two 701 opened at the top of the cylinder block 7 serves as the storage and preliminary distribution area of the irrigation liquid. Through the communication with the feeding groove 7011, it enables users to conveniently add water or nutrient solution into the annular groove two 701 through the feeding groove 7011 without disassembling any components, greatly simplifying the operation process. By arranging the plurality of cylinders 601 and the stirring rods 602 inside the annular groove two 701, when the fixed ring 6 rotates with the planting cylinder 3, it plays a role in fully stirring the irrigation liquid, ensuring that the nutrients in the liquid can be evenly distributed, and also avoiding precipitation or stratification phenomena caused by long-term static placement, thereby ensuring that each part of the sugarcane roots can obtain a balanced nutrient supply, enabling the sugarcane to grow normally, so as to accurately obtain the relevant index data of sugarcane under different water stress states of drought stress.

[0039] By starting the water pump controller 8, the two hollow tubes 9 can efficiently transport the liquid in the annular groove 701 to the annular tube 901, and then realize precise irrigation of the liquid through the inclined straight tube 1 9011 and the straight tube 2 9012. The bottom end of the straight tube 1 9011 is bent and is designed to be perpendicular to the bottom surface of the annular groove 302. The water in the straight tube 1 9011 can flow into the annular groove 302 better without affecting the rotation of the planting tube 3. The straight tube 2 9012 directly sprays the water to the roots of the sugarcane. When the planting tube 3 is rotated, the water in the straight tube 1 9011 can flow into the annular groove 302. When the cylindrical block 7 and the stirring system inside the cylindrical block 7 rotate, the cylindrical block 7 and the stirring system inside the cylindrical block 7 rotate, and the liquid in the annular groove 701 is continuously stirred through the connection between the fixing ring 6, the cylindrical block 601 and the stirring rod 602, thereby ensuring the uniformity of the irrigation liquid. The excess water flows downward along the threaded groove 301 on the outer wall of the planting tube 3, and finally flows into the collection box 13 after being filtered by the filter screen 12, which not only effectively avoids the waste of water resources, but also realizes the recycling of the irrigation liquid, and further improves the utilization rate of resources.

[0040] The working principle and use process of the present invention:

[0041] First, fill the planting tube 3 with soil. Plant the sugarcane in the planting tube 3, ensuring that the sugarcane is located in the middle of the annular tube 901 to achieve center positioning. Center positioning ensures that water is evenly supplied around the sugarcane root system, effectively preventing the sugarcane from growing eccentrically;

[0042] Water or nutrient solution is injected into the annular groove 2 701 through the feeding groove 7011, and the water pump controller 8 is started. The liquid in the annular groove 2 701 is sucked into the annular tube 901 through the two hollow tubes 9. The liquid is discharged into the annular groove 1 302 through the straight tube 1 9011 and is transmitted downward through the cylindrical groove 3021 to ensure that the bottom soil obtains moisture. The straight tube 2 9012 directly sprays the moisture to the roots of the sugarcane to achieve precise irrigation and nutrient solution supply, ensuring that all parts of the sugarcane root system can obtain sufficient moisture and nutrients, and the bottom soil can also obtain moisture to prevent growth problems caused by uneven moisture distribution.

[0043] By providing the root guide tube 5, the main root of the sugarcane is guided to grow downward, ensuring that the main root of the sugarcane grows deeply;

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

[0045] The rotation of the planting cylinder 3 drives the fixed ring 6 to rotate together, thereby driving the cylinder 601 and the stirring rod 602 to rotate. The stirring rod 602 fully stirs the liquid in the second annular groove 701 to ensure the uniform distribution of nutrients, improve the uniformity of water or nutrient solution, and ensure that all parts of the sugarcane can obtain a balanced nutrient supply.

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