Description

Technical Field

[0001] This utility model relates to the field of potato tissue culture technology, and in particular to a seedling device for culturing potato tissues. Background Technology

[0002] Potato tissue culture is a plant biotechnology that involves culturing a portion of a potato tissue (such as shoot tips, leaves, or tubers) under sterile conditions to promote its growth and differentiation. This process is typically carried out in a culture medium containing specific nutrients and plant hormones, with the aim of inducing the formation of new plant bodies. In this way, virus-free potato plants can be rapidly propagated, improving crop yield and quality. Furthermore, tissue culture can be used to preserve genetic resources, study plant development, and improve new varieties. Because it is conducted under controlled environmental conditions, this method reduces the impact of external environmental factors on plant growth, enabling precise genetic manipulation and efficient plant propagation.

[0003] In the prior art, a cultivation device for culturing potato tissue, for example, as described in application number CN202211501445.9, comprises: a cultivation platform including a plurality of vertically spaced frames and a horizontal frame connecting the vertical frames; a shelf that can slide on the horizontal frame, on which a cultivation container holding a small plantlet cultured in a culture medium is placed, and the shelf having a plurality of holes on its bottom surface; a light-emitting diode (LED) light source unit mounted on the cultivation platform and irradiating the cultivation container with a light beam; a coagulation measurement unit mounted in the shelf and measuring the coagulation phenomenon generated in the cultivation container by irradiating the cultivation container with infrared light; and a cooling unit mounted in the cultivation platform, electrically connected to the coagulation measurement unit, and circulating cooling water through the LED light source unit according to the coagulation information measured by the coagulation measurement unit, thereby controlling the temperature of the LED light source unit.

[0004] The above technical solution is used to solve the problems of reduced light transmission efficiency and inadequate plant tissue growth when condensation occurs in the culture container, as well as the problem of secondary contamination of plant tissue caused by water droplets condensing on the inner surface of the culture container falling onto the plant tissue.

[0005] However, in reality, it is impossible to completely prevent condensation from occurring in the cultivation container. Even if the temperature is kept constant, once the potato tubers sprout, the water vapor produced by the respiration of the sprouts and leaves, as well as the water vapor that naturally evaporates in the cultivation container, will condense on the inner top surface of the cultivation container. Therefore, a seedling device for cultivating potato tissue is proposed to solve or alleviate the above problems. Utility Model Content

[0030] A seedling cultivation device for culturing potato tissue, such as Figures 1 to 4 As shown, it includes a stand 1, a slide rail 2 fixedly connected to the stand 1, a shelf 3 that is horizontally movable within the stand 1, and a light 18 located above the shelf 3. Specifically, the shelf 3 is slidably connected to the slide rail 2.

[0031] The shelf 3 has a downward-facing recessed top surface to form a placement groove 4. Two sets of culture tanks 16 are arranged in the placement groove 4. A turntable 7 is rotatably arranged in the placement groove 4, located between and above the two sets of culture tanks 16. The two sets of culture tanks 16 are symmetrically arranged with respect to the central axis of the turntable 7. Specifically, a main bearing seat 10 is fixedly connected to the inner bottom surface of the placement groove 4. A drive shaft 9 is fixedly connected to the inner ring of the main bearing seat 10. A servo motor 6 is fixedly connected to the top surface of the shelf 3 through a connecting frame 5. The output shaft of the servo motor 6 is coaxially connected to the drive shaft 9. The turntable 7 is fixedly connected to the drive shaft 9. Several evenly spaced through slots are opened in the thickness direction of the turntable 7. The number of through slots is at least twice the number of culture tanks 16. A transparent light-transmitting cover 8 is fixedly connected in the through slots and can close the opening of the top surface of the culture tank 16. The inner top surface of the light-transmitting cover is concave upward to form a conical guide groove 11. The turntable 7 is arranged to rotate intermittently at equal angles around its central axis.

[0032] Two sets of rotating components are provided on the inner bottom surface of the placement tank 4. Two sets of culture tanks 16 are respectively set on the movable ends of the two sets of rotating components. The culture tanks 16 can perform circular motion on the movable ends of the rotating components. The rotating components include a rotation damper 12 fixedly connected to the inner bottom surface of the placement tank 4, a rotating shaft 13 fixedly connected to the inner ring of the rotation damper 12, and a support plate 14 fixedly connected to the upper end of the rotating shaft 13. The culture tanks 16 are detachably connected to the end face of the support plate 14. Several embedded posts 15 are fixedly connected to the end face of the support plate 14. The bottom surface of the culture tanks 16 is recessed upward to form a groove 17 that cooperates with the embedded posts 15.

[0033] In the actual process of cultivating potato tissue for seedlings, this utility model places potato tissue into a culture tank 16 filled with a certain amount of culture medium. Then, the culture tank 16 containing potato tissue is placed on the end face of a support plate 14, so that the insert 15 can be embedded in the groove 17 to prevent the culture tank 16 from being horizontally displaced relative to the support plate 14. Then, the support plate 14 is rotated manually, and the support plate 14 rotates relative to the rotation damper 12 through the rotating shaft 13, causing the culture tank 16 to move below the turntable 7, so that the light-transmitting cover 8 closes the top opening of the culture tank 16. Then, the lighting lamp 18 provides light and heat, so that the potato tissue can be cultivated in an environment with abundant light, suitable temperature, humidity and nutrients.

[0034] During this process, the water vapor generated by the evaporation of the culture medium will gather on the inner top surface of the light-transmitting cover 8 and condense. However, due to the setting of the guide groove 11, when the water vapor condenses into droplets, it will not drip directly downwards, thus avoiding the droplets directly hitting the potato tissue and preventing the potato tissue from being contaminated. Instead, it can flow along the direction of the guide groove 11, and then the droplets can slide down along the inner edge of the light-transmitting cover 8, and even flow back into the culture tank 16.

[0035] After a certain period of time, the servo motor 6 drives the transmission shaft 9 to rotate, which in turn drives the turntable 7 to rotate at certain angles. For example, if there are six light-transmitting covers 8, the rotation angle is 60° each time. This ensures that there are always as dry as possible light-transmitting covers 8 to seal the top opening of the culture tank 16, preventing excessive accumulation of liquid droplets on the inner top surface of the light-transmitting covers 8 due to condensation, which would then drip onto the potato tissue in the culture tank 16. The light-transmitting covers 8, which are no longer sealed but contain moisture, are exposed to the air. Under the light and heat emitted by the lamp 18, the liquid gradually evaporates, thus ensuring that it remains relatively dry when it rotates back above the culture tank 16. During this process, due to the setting of the rotation damper 12, it provides a certain resistance when rotating in the circumferential direction. The support plate 14 will only shift in angle if the friction between the light cover 8 and the culture tank 16 is greater than this resistance. Otherwise, the rotation damper 12 will ensure that the culture tank 16 is located directly below the light cover 8 and will not change position due to the rotation of the turntable 7.

[0036] Once the potato tissue has completed its seedling stage, people can manually pull the shelf 3 out of the slide rail 2, and then rotate the support plate 14 again to rotate the culture tank 16 to the side closer to people, making it easier for people to take out the seedling potato tissue.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
