Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydroponic equipment technology, and in particular to an experimental device suitable for outdoor cultivation of tea seedlings. Background Technology
[0002] Hydroponics is a soilless cultivation technique that does not use natural soil. Instead, it fixes the plant roots directly or through an inert substrate and fully immerses them in an artificially prepared nutrient solution. This technology creates more stable and optimized growth conditions for plants by precisely controlling key environmental factors such as water supply, nutrient concentration, and light intensity. As a result, it has outstanding advantages such as rapid growth, effective avoidance of soil-borne diseases and pests, significant water conservation, and intensive planting. It has been widely used in the large-scale production of vegetables, flowers, medicinal plants, and ornamental plants.
[0003] In recent years, hydroponics of tea seedlings has gradually become a research hotspot in the field of tea breeding and efficient propagation. Among them, conducting abiotic stress experiments on tea trees using hydroponic systems to explore their physiological and biochemical response mechanisms has become one of the hot research directions. By scientifically selecting suitable tea tree varieties, high-quality tea seedlings with well-developed root systems and robust growth can be efficiently cultivated in a controlled environment. This is not only conducive to meeting the research needs of standardized, industrialized, and large-scale production of tea seedlings as well as genetic breeding, but also fundamentally blocking soil-borne pathogens and pests, and significantly improving the survival rate and overall quality of seedlings.
[0004] However, in existing hydroponic seedling cultivation devices, the common method involves creating fixed holes in the cover to support the tea seedling stems and guide the roots into the nutrient solution. As the tea seedlings continue to grow, their root systems rapidly proliferate and expand in a clustered, divergent manner. When the seedlings need to be removed for transplanting at the end of the cultivation period, the perforated structure of the hard cover can easily cause compression, friction, and tearing of the dense root system, leading to severe root damage. This significantly affects the recovery speed and survival rate of the seedlings after transplanting, thus necessitating improvements. Utility Model Content

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0030] Example 1
[0031] As shown in the attached figure, an experimental device suitable for outdoor tea seedling cultivation includes a barrel 1, a barrel lid 2 covering the barrel 1, and a sponge block 3 for wrapping the seedlings; the barrel lid 2 has a through hole 4 in the middle to accommodate the sponge block 3; the barrel 1 and the barrel lid 2 are made of opaque material; the barrel lid 2 has a downwardly extending inverted frustum 5 at the through hole 4, and the lower end of the frustum 5 has an annular part 6; the barrel lid 2 is a split structure; the sponge block 3 is in the shape of an inverted frustum, placed inside the inverted frustum 5, and is a split structure.
[0032] As a preferred embodiment of this invention, the container 1 is provided with an overflow hole (not shown in the figure, but the same applies to other parts), and the overflow hole is provided with an opaque overflow pipe 7, which is a bent pipe. When the nutrient solution is overfilled or expands due to temperature changes, the excess liquid is discharged through the overflow hole and the bent opaque overflow pipe 7, preventing the liquid level from being too high and submerging the root-stem junction; the opaque and bent overflow pipe 7 can effectively block light from entering. The overflow pipe 7 can be connected to the container 1 by means of snap-fit or adhesive.
[0033] In one preferred embodiment of this invention, the overflow pipe 7 includes a horizontally extending section 8 and a downward-pointing drainage section 9. A limiting ring 10 is provided on the horizontal section 8. A box 12 for collecting overflow liquid is attached to the bent pipe via an inverted U-shaped hook 11. The overflowing nutrient solution flows through the horizontal section 8 to the drainage section 9 and is discharged. Simultaneously, the box 12 is suspended from the overflow pipe 7 via the inverted U-shaped hook 11, with the limiting ring 10 restricting its sliding position, thus collecting the discharged liquid. The box 12 achieves centralized recovery of overflow liquid, avoiding waste and environmental pollution. The hook structure is easy to assemble and disassemble, facilitating maintenance. The limiting ring 10 ensures the box 12 is stable and prevents it from falling off, improving the practicality and environmental friendliness of the device. The hook 11 and the box 12 can be integrally injection molded, or obviously, plastic bags or similar materials can be used as alternatives.
[0034] As a preferred embodiment of this invention, the tank lid 2 is provided with a liquid replenishment hole 13, and the liquid replenishment hole 13 is provided with an opaque liquid replenishment cover 14. By opening the liquid replenishment cover 14, the nutrient solution or water lost through evaporation can be replenished periodically to maintain a stable liquid level in the tank 1; the opaque liquid replenishment cover 14 can prevent light from entering through the liquid replenishment hole 13 and causing algae to multiply in the nutrient solution, keeping the system clean, extending the liquid change cycle, and reducing the frequency of maintenance.
[0035] As a preferred embodiment of this utility model, the barrel body 1 is provided with a handle 15. During use, the entire device can be easily carried or moved using the handle 15, facilitating indoor / outdoor transfer, placement / adjustment, or centralized management; significantly improving the portability and ease of operation of the device, and increasing its efficiency.
[0036] In this embodiment, when used for tea seedling cultivation, the tea seedling is inserted into the split-type sponge block 3, and then the sponge block 3 is embedded into the inverted frustum portion 5 of the bucket lid 2. The split-type bucket lid 2 is then closed and placed on top of the bucket body 1. Nutrient solution is injected into the bucket body 1 and soaks the roots. The opaque material effectively inhibits algae growth. The inverted frustum portion 5 and the ring portion 6 work together to provide stable guidance and support for the sponge block 3 and the roots. The split-type bucket lid 2 and sponge block 3 are designed for easy and damage-free separation after seedling cultivation, avoiding root damage from compression in the holes when removing the tea seedlings, significantly protecting the integrity of the roots and improving the transplant survival rate. At the same time, the inverted frustum structure helps to compress the sponge to clamp the tea seedlings, while the ring portion 6 supports the sponge block 3 to prevent it from falling off, improving seedling quality and ease of operation.
[0037] Example 2
[0038] As shown in the attached figure, an experimental device suitable for outdoor tea seedling cultivation includes a barrel 1, a barrel lid 2 covering the barrel 1, and a sponge block 3 for wrapping the seedlings; the barrel lid 2 has a through hole 4 in the middle for accommodating the sponge block 3; the barrel 1 and barrel lid 2 are made of opaque material; a downwardly extending guide portion 21 in the shape of an inverted frustum is provided at the through hole 4 of the barrel lid 2; the barrel lid 2 is a split structure; it also includes a separate receiving box 22 embedded in the guide portion 21, the receiving box 22 including a side wall 23 that fits into the guide portion 21, an overlapping portion 24 located at the upper end of the side wall 23 that overlaps with the through hole 4, and an annular support portion 25 located at the lower end of the side wall 23; the sponge block 3 is in the shape of an inverted frustum, placed inside the receiving box 22, and is a split structure. Its structure is basically the same as that of Embodiment 1, and will not be described again.
[0039] In this embodiment, when used for tea seedling cultivation, the split-type bucket lid 2 is first closed and placed on the bucket body 1. Then, the split sponge block 3 is used to hold the tea seedling and is placed into the container box 22. The tea seedling roots protrude from the bottom of the container box 22, making it easy to visually observe the length of the roots extending downwards. This allows for quick judgment and adjustment of the root position to a suitable depth in the early stages of seedling cultivation. Once the root length is adjusted to the correct position, the split container box 22 can be glued or fixed together using tape or temporary fasteners to prevent the tea seedlings from shifting or being damaged due to accidental separation of the container box 22 during operation. Subsequently, the fixed container box 22 is embedded into the inverted frustum-shaped guide part 21 on the bucket lid 2. The guide part 21 fits tightly with the side wall 23 of the container box 22, effectively limiting its radial movement and preventing separation, ensuring structural stability. Afterward, nutrient solution is injected into the bucket body 1 to moisten the tea seedling roots, and hydroponic seedling cultivation begins. During operation, the overlapping part 24 at the upper end of the container 22 overlaps with the edge of the through hole 4 of the lid 2, and the annular support part 25 at the lower end provides bottom support. Together, they prevent the sponge block 3 from sinking or falling off as the roots grow, ensuring that the roots are stably suspended in the nutrient solution and maintaining good ventilation and nutrient absorption. In this embodiment, the split lid 2, the split container 22, and the split sponge block 3 are designed in a coordinated manner, so that after the seedlings are cultivated, the tea seedlings can be removed without damage by opening the lid 2 and the container 22 horizontally. This completely avoids the root squeezing, friction, and tearing caused by the traditional vertical pulling method, maximizes the protection of the root integrity, and significantly improves the recovery speed and survival rate after transplanting. At the same time, the modular design of each component makes it easy to disassemble, clean, and reuse, improving the practicality, hygiene, and operational efficiency of the device.
[0040] In this invention, a 2L circular, individual polyethylene plastic container is used for hydroponic tea cultivation experiments. An overflow hole precisely controls the nutrient solution level to 1L. Depending on the experimental requirements, the prepared sterile nutrient solution is injected into the corresponding container. Four one-year-old Yun Kang 10 tea seedlings are planted in each container, secured with sponge blocks. A separate lid is fitted over the container to secure the seedlings. The sterile nutrient solution is changed weekly, and sterile foliar spraying is applied every 2-3 days to maintain plant moisture balance. The hydroponic seedlings are placed outdoors in a cool, well-ventilated area, avoiding direct sunlight. This invention meets the outdoor cultivation requirements for hydroponic tea cultivation experiments. Its opaque container and sealed structure effectively inhibit algae growth. Combined with aseptic procedures, a relatively sterile rhizosphere environment is maintained during seedling cultivation, ensuring high consistency of environmental factors across treatment groups, except for preset experimental variables, thus improving experimental repeatability and data reliability.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
