Description

Technical Field

[0001] This application relates to the technical field of sweet potato cultivation, and in particular to a device for rapid propagation of sweet potato tissue culture seedlings. Background Technology

[0002] Sweet potato tissue culture seedlings can inherit the superior traits of the parent plant through asexual reproduction, and the production efficiency is extremely high. The rapid propagation of sweet potato tissue culture seedlings is significantly different from the rapid propagation of other seedlings. The rapid propagation of other seedlings involves allowing healthy seedlings to take root, while the rapid propagation of sweet potato tissue culture seedlings involves first allowing the fragile seedlings to survive, and then allowing them to take root. Based on the aforementioned concept of rapid propagation of sweet potato tissue culture seedlings, it is necessary to provide the required conditions for rapid propagation. Compared with other seedlings, the new roots of sweet potato tissue culture seedlings are particularly fragile, and their requirements for soil temperature, moisture retention of new roots, and ventilation are exceptionally stringent. Existing rapid propagation devices for sweet potato tissue culture seedlings rely on heating the substrate with electric heating wires to maintain the root temperature. This results in significant temperature concentration and slow substrate temperature homogenization, which may cause the new roots of sweet potato tissue culture seedlings to be in a state of excessively high or low temperature, thus hindering the rapid propagation of sweet potato tissue culture seedlings. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a rapid propagation device for sweet potato tissue culture seedlings. In this embodiment, by setting up a layered cutting layer, a heating layer, and an aeration layer, the heat applied by the electric heating tube can be quickly homogenized within the substrate layer during the process of aeration pipes venting into the substrate. This maintains the temperature and gas flow of the cutting layer, providing better aeration and temperature conditions for the growth of sweet potato tissue culture seedlings, and ensuring that the propagation rate of sweet potato tissue culture seedlings is not affected.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: The sweet potato tissue culture seedling rapid propagation device includes a bed frame with openings at both the top and bottom and a hollow interior. A rigid mesh is fixed to the bottom of the bed frame to seal the opening at the bottom of the bed frame. The rigid mesh has several holes. The rigid mesh and the inner wall of the bed frame form a planting cavity with an open top. A non-woven permeable layer is laid on top of the rigid mesh. An air pipe is installed on the upper layer of the non-woven permeable layer. An electric heating pipe is installed above the air pipe. The non-woven permeable layer, air pipe, and electric heating pipe are all located inside the bed frame. The air pipe and electric heating pipe are fixed to the bed frame. The bed frame is also lined with a substrate layer, a non-woven permeable layer at the bottom of the substrate layer, and aeration pipes and electric heating pipes inside the substrate layer. There is a cutting layer between the top of the substrate layer and the electric heating pipes for sweet potato tissue culture seedlings to be propagated.

[0005] Optionally, there may be several ventilators, with the axes of the several ventilators parallel to each other and the axes of the several ventilators lying on the same horizontal plane.

[0006] Optionally, there are several electric heating elements, with the axes of the several electric heating elements parallel to each other, and the several electric heating elements are arranged in a wave-like pattern.

[0007] Optionally, when viewed from above, several ventilation pipes and several electric heating pipes are arranged alternately.

[0008] Optionally, a water tank with a top opening is also installed at the bottom of the bed frame. In the assembled state, the top opening of the water tank closes the bottom opening of the bed frame.

[0009] Optionally, one end of the vent pipe extends out of the bed frame and is inserted into the water storage tank, and an air pump is installed in the middle of the vent pipe.

[0010] Optionally, a vent is provided on the side of the water storage tank.

[0011] In summary, this application has the following beneficial technical effects: This embodiment of the application sets up a layered cutting layer, a heating layer, and a ventilation layer. This allows the heat applied by the electric heating pipe to be quickly homogenized within the substrate layer during the ventilation process, maintaining the temperature and gas flow of the cutting layer. This provides better ventilation and temperature conditions for the growth of sweet potato tissue culture seedlings, ensuring that the propagation rate of sweet potato tissue culture seedlings is not affected.

[0014] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0015] This application provides a device for rapid propagation of sweet potato tissue culture seedlings, including a rectangular frame-shaped bed frame 10 with openings at both ends and a hollow interior. A rigid mesh 11 for sealing the bottom opening of the bed frame is fixed to the bottom of the bed frame 10. The rigid mesh 11 has several holes. The rigid mesh 11 and the inner wall of the bed frame 10 form a planting cavity 12 with an open top. A non-woven permeable layer 13 is laid on top of the rigid mesh 11. An air pipe 14 is arranged above the non-woven permeable layer 13. An electric heating pipe 15 is arranged above the air pipe 14. The air pipe 14 has several holes for ventilation. The outside of the holes is covered with a breathable mesh to isolate light substrate particles. The non-woven permeable layer 13 is located inside the bed frame 10, and the working parts of the air pipe 14 and the electric heating pipe 15 are located inside the bed frame 10. The tubular air pipe 14 and the electric heating pipe 15 can be fixed on the bed frame 10. The bed frame 10 is also lined with a substrate layer 16, a non-woven permeable layer 13 is located at the bottom of the substrate layer 16, an air pipe 14 and an electric heating pipe 15 are located inside the substrate layer 16, and there is a cutting layer 17 between the top of the substrate layer 16 and the electric heating pipe 15 for sweet potato tissue culture seedling cuttings.

[0016] The following section will provide further details based on specific usage scenarios.

[0017] In use, the operator first lays a non-woven permeable layer 13, and then lays a lightweight substrate, such as a mixture of perlite and vermiculite, on the non-woven permeable layer 13 to form a substrate layer 16. The lightweight substrate particles have a large diameter, and the air-permeable mesh outside the holes on the air pipe 14 can isolate most of the lightweight substrate particles. It should be noted that the area above the electric heating tube 15 in the substrate layer 16 is the cutting layer 17, which is suitable for tissue culture seedling cuttings. The operator can insert the stem base of the tissue culture seedling into the cutting layer 17 for rapid propagation.

[0018] During the propagation of tissue culture seedlings, the electric heating tube 15 is located inside the substrate layer 16, and the ventilation tube 14 is located at the bottom of the electric heating tube 15. When the ventilation tube 14 vents into the substrate layer 16, the upward airflow is heated, which makes the heat inside the substrate layer 16 quickly homogenize, so that the temperature of the entire cutting layer 17 tends to the predetermined temperature.

[0019] In summary, the embodiments of this application, by setting up a layered cutting layer 17, a heating layer, and a ventilation layer, enable the heat applied by the electric heating pipe 15 to be quickly homogenized within the substrate layer 16 during the ventilation process of the ventilation pipe 14 into the substrate layer. This maintains the temperature and gas flow of the cutting layer 17, providing better ventilation and temperature conditions for the growth of sweet potato tissue culture seedlings, and ensuring that the propagation rate of sweet potato tissue culture seedlings is not affected.

[0020] In this embodiment, there are several vent pipes 14, the axes of which are parallel to each other and are on the same horizontal plane. There are also several electric heating tubes 15, the axes of which are parallel to each other and are arranged in a wave pattern. By setting up several vent pipes 14 and electric heating tubes 15, the temperature and permeability of a large area of ​​matrix layer 16 can be effectively maintained. Furthermore, the wave pattern of the electric heating tubes 15 is also conducive to temperature stability and alleviates the situation of local heat accumulation.

[0021] Based on this, when viewed from above, the bed frame 10 has several ventilation pipes 14 and several electric heating pipes 15 arranged in an alternating pattern, which further alleviates the local heat accumulation and improves the temperature homogenization and retention effect of the matrix layer 16.

[0022] Several vent pipes can be connected to the same static pressure chamber, allowing a single air pump to supply air to the vent pipes, and several electric heating elements to be controlled by a centralized controller.

[0023] In this embodiment of the application, a water storage tank 18 with a top opening is also installed at the bottom of the bed frame 10. In the assembled state, the top opening of the water storage tank 18 closes the bottom opening of the bed frame 10. One end of the air pipe 14 extends out of the bed frame 10 and is inserted into the water storage tank 18. An air pump 19 is provided in the middle of the air pipe 14, and an air vent is provided on the side of the water storage tank 18.

[0024] In a specific application scenario, the water inside the water tank 18 rises through natural evaporation, which can moisten the substrate layer 16. Compared with irrigation, this is more in line with the growth habits of sweet potato tissue culture seedlings, so that the propagation rate of sweet potato tissue culture seedlings is not affected. On this basis, the ventilation pipe 14 can quickly draw the water vapor that evaporates naturally in the water tank 18 into the substrate layer 16 through the air pump 19, so as to keep the stem base and new roots moist.

[0025] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
