Description

Technical Field

[0001] This utility model relates to the field of plant cultivation technology, and more specifically, to a plant cultivation device. Background Technology

[0002] With the rapid development of agriculture and biotechnology, tissue culture technology has become an important means of producing high-yield, high-quality plants and plant products. Among them, liquid-phase bioreactors are the most studied bioreactors in the field of tissue culture. In a liquid-phase bioreactor, cells are immersed in a culture medium. The most commonly used liquid-phase bioreactors include mechanically stirred, pneumatically stirred, hydraulically stirred, and membrane bioreactors. These bioreactors have various applications in the field of tissue culture. However, the main limitation of liquid-phase bioreactors is that the continuous liquid phase conditions lead to vitrification and high water content in plant tissues. This can result in culture deformities and material loss.

[0003] To address the aforementioned technical challenges, temporary submerged bioreactors offer an effective method for tissue culture. This technique provides suitable growth conditions by periodically immersing plant tissues in a nutrient solution, rather than relying on the continuous liquid phase conditions of traditional liquid-phase bioreactors. Compared to liquid-phase bioreactors, temporary submerged bioreactors significantly reduce mechanical damage to plants caused by agitation and minimize contamination from unnecessary prolonged exposure to the solution. Furthermore, they offer advantages such as simple operation, high production efficiency, and excellent aeration, making them particularly suitable for plant tissue culture.

[0004] However, for small-scale businesses or plant cultivation enthusiasts, existing temporary submerged bioreactors are relatively complex in design and require a large amount of space. Therefore, providing a temporary submerged bioreactor that is space-saving, simple in structure, and easy to use has become an urgent problem to be solved. Utility Model Content

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

[0031] Please see Figures 1-4 As shown, the main body of this embodiment is a plant cultivation device, including a liquid placement bottle 1 and a plant cultivation bottle 2. The bottle mouth of the liquid placement bottle 1 and the bottle mouth of the plant cultivation bottle 2 are threadedly connected to both ends of a bidirectional connecting sleeve 3. A sealing elastic ring 4 is fixedly sleeved on the inner side of the bidirectional connecting sleeve 3. The diameter of the sealing elastic ring 4 matches the bottle mouth of the liquid placement bottle 1 and the bottle mouth of the plant cultivation bottle 2.

[0032] Furthermore, the inner side of the bidirectional connecting sleeve 3 is provided with a mounting plate 5, and the mounting plate 5 has a mounting through hole 6 coaxial with the bidirectional connecting sleeve 3. A bacterial filter screen 7 is fixedly fitted inside the mounting through hole 6. Two sealing elastic rings 4 are provided, located above and below the mounting plate respectively. The inner diameter of the mounting through hole 6 is smaller than the inner diameter of the sealing elastic ring 4. The bacterial filter screen 7 adopts an APCM antibacterial filter membrane, which reduces the decrease in the flow rate of the liquid culture medium while ensuring the bacterial filtration effect.

[0033] Furthermore, one side of the bidirectional connecting sleeve 3 is provided with an insertion through hole 8, which extends into the inner side of the bidirectional connecting sleeve 3; the mounting plate 5 is slidably connected to the inner side of the insertion through hole 8.

[0034] Furthermore, the end face of the sealing elastic ring 4 extends into the insertion through hole 8, and both the upper and lower end faces of the mounting plate are respectively provided with annular grooves 9 that cooperate with the sealing elastic ring 4.

[0035] Furthermore, the inner side of the sealing elastic ring 4 is fixedly sleeved with a flow plate 10; the flow plate 10 is provided with a plurality of strip-shaped flow holes 11.

[0036] Furthermore, a rigid support ring 12 is fitted inside the sealing elastic ring 4.

[0037] Furthermore, the plant culture bottle 2 is detachably connected to a plant root fixing mechanism; the plant root fixing mechanism includes a conical spiral coiled elastic tube 13, the bottom of the elastic tube 13 is fixedly connected to an elastic fixing ring 14, and the bottom inner side of the plant culture bottle 2 is provided with a locking groove 15 that cooperates with the elastic fixing ring 14.

[0038] Furthermore, a handle 16 is fixedly connected to the top of the elastic tube 13.

[0039] Furthermore, the bottom of the plant culture bottle 2 is provided with a PTFE microporous membrane 17.

[0040] First, the liquid culture medium is placed into the liquid placement bottle 1. Then, one end of the bidirectional connecting sleeve 3 is fitted onto the mouth of the liquid placement bottle 1 and tightened. The mouth of the liquid placement bottle 1 abuts against the sealing elastic ring 4 located below. The plant tissue is then placed into the plant culture bottle 2, and the other end of the plant culture bottle 2 is tightened to complete the installation. Under normal conditions, the liquid placement bottle 1 is located below, and the plant culture bottle 2 is located above. When it is necessary to immerse the plant tissue in the liquid culture medium, the entire device is inverted so that the plant culture bottle 2 is located below. Under the action of gravity, the liquid culture medium enters the plant culture bottle 2 through the through holes on the flow plate 10 and the bacterial filter 7 for immersion. After immersion for the appropriate time, the device is inverted again, and the liquid culture medium returns to the liquid placement bottle 1, thereby achieving a temporary immersion effect on the plant tissue.

[0041] In addition, the bacterial filter 7 can effectively prevent bacteria that may be present in the liquid culture medium from entering the plant culture bottle 2 and causing plant tissue contamination; the flow plate 10 buffers the liquid culture medium when it is inverted, preventing it from directly impacting the bacterial filter 7 and causing damage to the bacterial filter 7.

[0042] In addition, the rigid support ring 12 improves the connection strength between the sealing elastic ring 4 and the bidirectional connecting sleeve 3 and the flow plate 10.

[0043] Furthermore, as plant tissues grow, their roots become increasingly long, leading to tangling and intertwining of roots from multiple plant tissues after a certain number of days of cultivation, hindering the separation of plant tissues. Therefore, a conical spiral-shaped elastic tube 13 is designed. This elastic tube 13 provides a fulcrum for the plant tissue's roots to anchor, effectively solving the aforementioned problem. Additionally, the handle 16 facilitates the removal of the elastic tube 13 and the plant tissue from the bottle. The engagement of the elastic retaining ring 14 with the locking groove 15 enables a detachable connection between the elastic tube 13 and the plant culture bottle 2.

[0044] Furthermore, the PTFE microporous membrane 17 at the bottom of the plant culture bottle 2 enables the exchange of external air with the gas inside the bottle, facilitating plant tissue respiration while preventing leakage of the liquid culture medium. Additionally, the PTFE microporous membrane effectively filters out fine particulate matter and bacteria from the air, preventing contamination of the plant tissue.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
