Description

Technical Field

[0001] The utility model relates to the field of plant cultivation and water technology, in particular to a hydroponic device for observing plant roots. Background Art

[0002] In botanical and agricultural science research, the observation and study of plant roots is of vital importance. As an important organ of plants, the root system is directly involved in key physiological processes such as nutrient absorption, water transport, and soil fixation. Therefore, a deep understanding of the growth characteristics, morphological changes, and interactions with environmental factors of plant roots is of great significance for improving crop yields, optimizing planting techniques, and understanding plant ecological functions. Traditional soil cultivation methods cause plant roots to be deeply buried in the soil, making them difficult to observe directly. Hydroponics, as a soilless cultivation technology, provides convenience for observing and studying the root system by directly exposing the plant roots to the nutrient solution.

[0003] However, existing hydroponic devices still have certain limitations in root observation. The housing design of most hydroponic devices is opaque or has low transparency, which makes it difficult to clearly observe the growth of the root system. Even with the use of transparent materials, it is still difficult to obtain satisfactory observation results due to unreasonable design of the root growth area or light obstruction. At the same time, the light transmission of transparent materials causes the hydroponic solution to breed green algae, affecting the observation of plant roots. In addition, existing hydroponic devices lack specificity in the setting of the root observation area. Although some devices provide observation windows, the window position is fixed and the size is limited, which cannot meet the observation needs of different plant species and growth stages.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-4 As shown, the utility model provides a hydroponic device for observing plant roots, including a box body 1, a hollow structure with an opening at the top of the box body 1, a plant growth support plate frame 2 matching it is provided at the top opening of the box body 1, a filter screen 3 is carried on the inner side of the plant growth support plate frame 2, and a connecting component 4 for realizing quick disassembly and assembly of the filter screen 3 is provided at the bottom of the plant growth support plate frame 2, a retractable curtain component 5 is provided on the outside of the box body 1, and the retractable curtain component 5 includes a cylinder 51, which is fixedly arranged on one of the edges on the outside of the box body 1, and a retractable shading curtain 52 is provided in the cylinder 51, and the shading curtain 52 can be pulled out from the cylinder 51 to achieve shading of the box body 1.

[0025] In this embodiment, the box body 1 is a rectangular parallelepiped with equal size at the top and bottom, and the height of the box body 1 can be designed to be 15 cm, and the upper and lower sides can be designed to be 15 cm long and 10 cm wide. The plant growth support plate frame 2 adopts a rectangular design with a length of 14 cm and a width of 9 cm. The plant growth support plate frame 2 is provided with an edge 21 located on the box body 1. The length and width of the plant growth support plate frame 2 including the edge 21 are 16 cm and 11 cm respectively. The plant growth support plate frame 2 uses the edge 21 to be placed at the opening above the box body 1.

[0026] In this embodiment, a "cross"-shaped support rod 22 is fixedly provided on the inner side of the plant growth support plate frame 2, and a through hole 23 is provided on the support rod 22. A countersunk connector 6 is provided on the filter screen 3. One side of the bottom end of the countersunk connector 6 passes through the filter screen 3 and the support rod 22 and extends to the bottom of the support rod 22. A connecting hole 61 located below the support rod 22 is opened on the countersunk connector 6. The connecting component 4 includes a fixed cylinder 41 fixedly provided at the bottom of the support rod 22, and a connecting rod 42 is inserted into the fixing cylinder 41. One end of the connecting rod 42 is inserted into the connecting hole 61, and the other end of the connecting rod 42 is provided with a pull ring 43. A limiting ring 44 located in the fixing cylinder 41 is fixedly sleeved on the outer wall of the connecting rod 42, and the side of the limiting ring 44 A spring 45 is fixedly connected and sleeved on the outside of the connecting rod 42. The end of the spring 45 away from the limit ring 44 is in low contact with the inner wall of the fixed cylinder 41. When the filter 3 is installed, it is placed on the support rod 22, and the countersunk connector 6 passes through the filter 3 and the through hole 23. The connecting rod 42 is inserted into the connecting hole 61 to fix the countersunk connector 6 to complete the installation of the filter 3. The aperture of the filter 3 should be adapted to the plant, so as to ensure that the roots grow only in the box body 1, but at the same time do not affect the roots' absorption and utilization of nutrients in the hydroponic solution. Therefore, the filter 3 needs to be cleaned and replaced according to actual conditions. Just pull the pull ring 43 to separate the connecting rod 42 from the connecting hole 61, and then remove the countersunk connector 6 to replace the filter 3 with a different aperture.

[0027] In this embodiment, the retractable curtain assembly 5 also includes a fixed shaft 53 fixedly arranged inside the cylinder 51. The fixed shaft 53 is concentric with the cylinder 51. The outer wall of the fixed shaft 53 is sleeved with a rotating cylinder 54. The rotating cylinder 54 rotates with the fixed shaft 53. A coil spring 55 is arranged between the rotating cylinder 54 and the fixed shaft 53. The coil spring 55 is in a rolled-up state. One end of the coil spring 55 is connected to the outer wall of the fixed shaft 53, and the other end of the coil spring 55 is connected to the rotating cylinder 54. The light-shielding curtain 52 is wound around the outer wall of the rotating cylinder 54. The light-shielding curtain 52 is pulled out from the cylinder 51 to block the box body 1. When the light-shielding curtain 52 is pulled out, it drives the rotating cylinder 54 to rotate to store force in the coil spring 55. When the light-shielding curtain 52 is released, it will be reset under the elastic force of the coil spring 55, which is more convenient to use.

[0028] In this embodiment, the side of the shading curtain 52 away from the rotating drum 54 passes through and extends to the outside of the cylinder 51. A buckle 56 is provided on the side of the shading curtain 52 outside the cylinder 51. The cylinder 51 is fixed with a hook 57 matching the buckle 56. The buckle 56 can cooperate with the hook 57 to realize the fixation of the shading curtain 52 to the box body 1 after blocking and shading.

[0029] In this embodiment, the box body 1 is made of high-transparency material, and the edges of the box body 1 except the edge connected to the cylinder 51 are chamfered. The box body 1 is made of high-transparency material so that the growth of the plant roots can be clearly seen, and can be directly observed without taking out the plants. The chamfer setting can reduce scratches on the blackout curtain 52.

[0030] How to use and working principle of this device:

[0031] First, the filter 3 of appropriate pore size is rotated according to the plant species, so as to ensure that the roots grow only in the box body 1, but at the same time do not affect the absorption and utilization of nutrients in the hydroponic solution by the roots. The filter 3 is placed on the support rod 22 in the plant growth support plate frame 2, and the countersunk connector 6 passes through the filter 3 and the through hole 23. The connecting rod 42 is inserted into the connecting hole 61 to fix the countersunk connector 6, thereby completing the installation of the filter 3. The filter 3 can be quickly installed and removed through the connecting assembly 4, so that the filter 3 of different pore sizes can be replaced according to different types of plants. It is easy to use and has a wide applicability, ensuring stable growth of plants.

[0032] Secondly, the box body 1 is used to hold the hydroponic nutrient solution, while the plant growth support frame 2 combined with the filter 3 is used to hold and fix the plant seedlings. The plant growth support frame 2 equipped with the filter 3 is placed on the box body 1 through the edge 21 to ensure that the plants can grow normally in the nutrient solution, and the plant roots only grow in the box body 1;

[0033] Then, when the plants grow, the shading curtain 52 is pulled out of the cylinder 51 by the snap ring, and the shading curtain 52 is fixed by the cooperation of the snap ring and the hook 57, thereby shielding the box body 1 from light and ensuring that no light is transmitted. The roots grow in darkness, which is more in line with the lightless environment in the soil and prevents the growth of green algae.

[0034] When observing the root system at a specific time point, the clamp ring and the clamp hook 57 are separated, and the light-shielding curtain 52 is automatically retracted under the elastic force of the coil spring 55, and then observation is carried out, so that the growth of the plant root system can be clearly seen, and direct observation can be made without removing the plant;

[0035] On the other hand, when the hydroponic solution needs to be replaced for related nutritional metabolism research or stress induction research, the plant growth support plate 2 with the plants fixed thereon can be directly removed and the hydroponic solution in the outer box 1 can be replaced, which can minimize the impact on plant growth and cultivation.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
