Description

Technical Field

[0001] This utility model belongs to the field of plant cultivation technology, specifically relating to a non-toxic plant cultivation device. Background Technology

[0002] Virus-free cultivation refers to the process of avoiding contamination of plant cultures by harmful microorganisms and chemicals during plant tissue culture, ensuring the purity and health of the cultures, thereby improving the success rate and quality of plant cultivation. According to long-term scientific research, the main reason for the decline in crop quality is infection by plant viruses. To achieve high yields, it is essential to cultivate virus-free seedlings, also known as virus-free seedlings, which is the concept of virus-free seedlings.

[0003] In existing technologies for the virus-free cultivation of seedlings, cultivation tanks are commonly used. These tanks consist of a body and a top cover, with the top cover typically connected to the body via threads or snap-fit ​​connections. In practice, the culture medium and plant tissues are placed inside the tank for cultivation. However, as the plants grow and their foliage becomes abundant, the small opening at the top of the tank makes it inconvenient to remove the seedlings from the bottom up, hindering transplantation and potentially damaging the leaves. Furthermore, the snap-fit ​​connection of the top cover to the body in some cultivation tanks results in relatively poor sealing performance. Utility Model Content

[0021] Figure 4 This is another embodiment of the distribution method of the cultivation device. Detailed Implementation

[0022] The following will be based on the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0023] like Figure 1 , Figure 2A non-toxic plant cultivation device includes a cylinder 1, a top cover 2, a cultivation base 3, and a base 4;

[0024] The top cover 2 is provided on the top of the cylinder 1;

[0025] The base 4 is used to place the culture seat 3. The base 4 is provided with an annular groove around the culture seat 3. The cylinder 1 is used to fasten onto the annular groove and to accommodate the culture seat 3 inside. An annular isolation cavity 401 is formed between the outer side of the cylinder 1 and the wall of the annular groove. Water is injected into the annular isolation cavity 401 to form a sealing structure.

[0026] The culture stand 3 is used to hold the culture medium and the tissue to be cultured, so as to achieve the function of non-toxic tissue culture.

[0027] Both the culture medium and the tissue to be cultured are existing technologies. The preferred tissue is the stem tip of a plant, as the auxin content in the stem tip meristem is very high, which can inhibit virus proliferation. Healthy plants free from diseases and pests and of pure varieties are selected. Stem tips of 2-3 cm with growth points and 1-2 leaf primordia are cut off, sterilized, and then placed in the culture medium for cultivation. The culture medium is prepared by mixing inorganic salts, trace elements, organic components, plant hormones, sugars, and agar. Generally, a high concentration of ammonium and potassium salts is beneficial to the survival of the stem tips.

[0028] In practice, the culture medium and the tissue to be cultured are placed in the culture holder 3, which is then placed on the base 4. The cylinder 1 is then fastened into the annular groove of the base 4, and water is injected into the annular isolation chamber 401. During the cultivation process, the water in the annular isolation chamber 401 forms a seal, preventing external contaminants from entering the cylinder 1. The water in the annular isolation chamber 401 blocks the exchange of gases and substances between the inside and outside of the cylinder 1 through a liquid seal, preventing external bacteria and impurities from contaminating the tissue in the culture holder 3. The top cover 2, in conjunction with the cylinder 1, further seals the internal space, creating an independent aseptic culture environment. The tissue to be cultured grows in this sealed space, becoming a virus-free seedling, achieving the goal of virus-free cultivation. After cultivation, the cylinder 1 is simply removed upwards to remove the culture holder 3, and then the virus-free seedling is taken out for transplantation. The entire process is simple and quick.

[0029] This invention achieves efficient isolation through a water-sealed structure, preventing external pollution from entering and providing a stable, non-toxic growth environment for plant tissues. After cultivation, the cylinder 1 and culture base 3 can be removed directly in sequence, making the operation simple, quick, and convenient for removing the virus-free seedlings for transplanting.

[0030] Furthermore, the bottom of the culture base 3 is provided with a positioning groove, and the base 4 is provided with a protrusion that mates with the positioning groove. When placing the culture base 3, the positioning groove at the bottom of the culture base 3 is aligned with the protrusion of the base 4, so that the two fit together, completing the fixation and limiting of the culture base 3 on the base 4, ensuring the stability of the position of the culture base 3, and ensuring that the culture base 3 is always in the central area inside the cylinder 1.

[0031] Furthermore, there is an annular gap between the outer wall surface of the culture base 3 and the inner wall surface of the cylinder 1.

[0032] Furthermore, a water passage hole 103 is provided at the bottom of the cylinder 1, and the annular isolation cavity 401 and the annular spacer are connected through the water passage hole 103.

[0033] When water is injected into the annular isolation chamber 401, the water flows into the annular spacer through the water passage 103, keeping the water levels in the two areas balanced. When draining, the water can also flow back from the annular spacer to the annular isolation chamber 401 through the water passage 103. The water passage 103 enables fluid communication between the annular isolation chamber 401 and the annular spacer, allowing water to circulate between them and enhancing the sealing effect.

[0034] Furthermore, the bottom of the top cover 2 is located inside the cylinder 1, and the bottom of the top cover 2 has an arc-shaped structure.

[0035] The top cover 2 and the cylinder 1 can be fixedly connected or detachably connected by bolts, threads, etc. The purpose of the arc-shaped structure at the bottom of the top cover 2 is to guide the flow. During the cultivation process, water droplets that condense and liquefy are easily generated at the bottom of the top cover 2. Through the design of the arc-shaped structure, the water droplets can accumulate and fall into the cultivation seat 3 instead of falling into the annular interval, thereby avoiding contamination of the pure water in the annular isolation chamber 401, avoiding the exchange of substances between the internal and external environments, and also avoiding water loss.

[0036] Furthermore, a water-blocking ring 102 is fixedly connected inside the cylinder 1. The water-blocking ring 102 is located above the culture base 3, and the inner diameter of the water-blocking ring 102 is smaller than the outer diameter of the culture base 3. An annular cover plate 101 is fixedly connected to the outer side of the cylinder 1, and the annular cover plate 101 covers the opening on the upper end face of the annular isolation cavity 401.

[0037] The water-blocking ring 102 blocks water droplets sliding down the inner wall of the cylinder 1 inside the cylinder 1, causing them to fall into the culture base 3 along the water-blocking ring 102. The water-blocking ring 102 and the arc-shaped structure of the top cover 2 have the same function: to prevent condensate from entering the annular gap during the cultivation process.

[0038] Furthermore, the cylinder 1, the top cover 2, and the culture base 3 are all made of transparent materials, such as plastic and glass.

[0039] Furthermore, the base 4, the cylinder 1, the top cover 2 and the culture seat 3 are respectively provided with multiple annular isolation cavities 401. Multiple annular isolation cavities 401 are connected end to end by connecting pipes 6. The annular isolation cavities 401 located at both ends are connected to the water tank and the pump body by water inlet pipe 5 and water return pipe 7, respectively.

[0040] After the pump starts, water in the tank flows into the first annular isolation chamber 401 through the inlet pipe 5, then flows through the remaining annular isolation chambers 401 in sequence through the connecting pipe 6, and finally flows back to the tank through the return pipe 7, forming a water circulation system. This allows for simultaneous water filling of multiple annular isolation chambers 401. The water in the tank is preferably purified water.

[0041] like Figure 3 , Figure 4 The multiple cultivation devices of this utility model can be arranged side by side or distributed in a rectangular array.

[0042] Furthermore, a heating device is installed inside the water tank.

[0043] The heating device is an existing technology, such as a heating rod or electric heating wire, used to heat the water in the tank to maintain a constant water temperature. After activation, the heating device heats the water in the tank, and the hot water flows through the annular isolation chambers 401 and the annular spacers. Because the water in the annular spacers surrounds the bottom of the culture base 3, a surrounding water bath heating is formed at the bottom of the culture base 3, keeping the culture medium inside the culture base 3 at a constant temperature, which is beneficial for the growth of the cultured tissue. At the same time, the water bath heating method can evenly transfer heat, especially in low-temperature environments, ensuring normal tissue development and improving the success rate of culture.

[0044] In addition, supplemental lighting can be provided during cultivation.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
