Description

Technical Field

[0001] This utility model belongs to the technical field of seed germination devices, and more specifically relates to a seed germination box and a germination device. Background Technology

[0002] Experiments such as exploring seed germination conditions, measuring seed germination rate, and observing root hairs of young plant roots are an important series of experiments in junior high school biology.

[0003] Currently, seed germination experiments typically involve placing seeds directly in bottles or petri dishes lined with absorbent paper or paper towels, or fixing the seeds in special containers. These methods either cause the seeds to move easily, potentially damaging the root and shoot tips during germination, or make continuous monitoring and measurement during germination difficult. More importantly, the radicle cannot grow downwards during germination, and the shoot cannot easily grow upwards. Furthermore, temperature control during seed germination experiments relies either on comparing germination at 4°C with room temperature or using a laboratory incubator for constant temperature cultivation, which is extremely inconvenient for experiments where germination lasts for several days.

[0004] Besides temperature, seeds require certain humidity and ventilation conditions to germinate properly. However, it is often difficult to satisfy both moisture retention and ventilation at the same time. Current experiments generally use damp filter paper or paper towels in the culture dish to maintain humidity, but adding too much water during the operation can easily lead to the young roots being soaked, affecting root respiration and causing abnormal seed germination.

[0005] Furthermore, some seeds require light stimulation to germinate, but existing experimental methods do not explain how to do this. Moreover, refrigerators or incubators generally do not have lighting facilities, making it difficult to conduct light and darkness contrast experiments simultaneously under certain germination temperature and humidity conditions. Utility Model Content

[0006] To overcome the shortcomings and deficiencies of the existing technology, this utility model provides a seed germination box and a germination device. To achieve the above objectives, this utility model adopts the following technical solution: This utility model provides a seed germination box, including a box body and a box cover adapted to and connected to the box body. The side of the box body has multiple elongated ventilation / water filling holes arranged side by side, and the bottom of the box body has multiple circular ventilation / water filling holes. The interior of the box is lined with multiple layers of absorbent medium from bottom to top. A gap exists between the lid and the absorbent medium, the height of which is less than the seed diameter. This allows the seeds to be held in place by the sponge-like elasticity within the absorbent medium. It should be understood that "diameter" here refers to the length of the seed's center portion laterally.

[0007] Furthermore, both the box body and the box lid are made of transparent material.

[0008] Furthermore, the absorbent medium includes a sponge and a velvet cloth. The sponge and velvet cloth are laid sequentially from the bottom to the top of the box.

[0009] Furthermore, the transparent material is an acrylic plexiglass sheet.

[0010] A second aspect of this utility model provides a seed germination device, comprising the seed germination box and germination instrument described above; the seed germination box is placed upright in the germination instrument; The germination device includes a control base (temperature control), a container, and a bottom liner; the container is mounted on the control base, and the bottom liner is placed at the bottom of the container; the product model is SXR-01. The germination boxes are placed inside the housing. Preferably, four germination boxes are placed upright inside the germination device, and the sum of the bottom length and height of the germination boxes matches the inner diameter of the housing to prevent the germination boxes from tipping over. For example, the sum of the bottom length and height of the germination boxes is approximately equal to the inner diameter of the housing, thus allowing the germination boxes to support each other.

[0011] Furthermore, it also includes light-blocking cloth, water dropper, and petri dish. Or, further, it also includes light-blocking cloth, absorbent cloth, water dropper, and petri dish.

[0012] The third aspect of this utility model provides a seed germination method, in which germination is performed using the aforementioned germination device, the process comprising: 1) Soak the seeds in a petri dish until they absorb the liquid and swell, then set aside. 2) Set the germination temperature of the germination device; 3) Clean the sponge and velvet, squeeze out excess water, and place them into the germination box. Smooth the absorbent velvet, place the swollen seeds on the velvet surface according to the experimental design, close the lid, and then place the germination box upright in the germination device to wait for the seeds to germinate. 4) If water needs to be added during germination, take out the germination box and add an appropriate amount of purified water through the water inlet using a Pasteur pipette.

[0013] As can be seen from the above technical solution, compared with the prior art, the technical effect achieved by the present utility model is as follows: 1) The transparent lid of the germination box of this utility model, together with the water-absorbing sponge and velvet inside the box, fixes the seeds in a specific position, so that the seeds do not move throughout the germination cycle, preventing damage to the young roots and buds during observation and measurement. Moreover, in this utility model, the germination box is placed upright in the germination instrument, ensuring that the young roots grow towards the ground and the buds grow upward during the germination process, which conforms to the natural growth law of the seeds.

[0014] 2) This invention uses a germination device to control the germination temperature, allowing the temperature to be freely adjusted within the range of 20℃ to 40℃, facilitating experimental research on the effects of different temperatures on germination. The instrument is compact, features a bottom circuit board heating element, touch-sensitive digital temperature control, USB power supply, low power consumption, simple operation, and safe use, making it particularly suitable for middle school students to conduct exploratory experiments at home.

[0015] 3) Besides temperature, seeds require specific humidity and ventilation conditions to germinate properly. However, achieving both moisture retention and ventilation simultaneously is often difficult. This germination box effectively solves these problems. The lid of the germination box is made of acrylic glass, with ventilation / water filling holes of different shapes on the other five sides. Inside the box, a damp sponge and a moisture-retaining cloth are placed. The moisture content of the sponge and cloth can be controlled manually, thus effectively meeting the necessary moisture retention and ventilation conditions for seed germination.

[0016] 4) Regarding the issue of light control, except for the base of the germination device, all the above parts and the germination box of this utility model are made of acrylic high-transparency organic glass, which has a very good transparency effect. When treating germination in the dark, it is only necessary to fix the black cloth to the outside of the corresponding germination device panel with rubber bands. Moreover, the black cloth does not affect the normal light transmission of the other three sides, which is suitable for the contrast treatment of darkness and light under the same conditions. The operation is extremely convenient.

[0017] 5) Flexible operation: The germination device of this utility model includes a germination instrument and a germination box, and also provides 4 square plastic petri dishes and 8 kinds of seeds. The water absorption step of seed germination can be completed in the petri dish. The germination rate of all 8 kinds of seeds is over 95%. Germination can be compared according to the design, providing multiple options for germination exploration. It is convenient for students to carry out various germination exploration activities according to their own experimental ideas and designs, which is conducive to the cultivation of students' innovative ability.

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Most existing seed germination devices used in junior high school biology teaching lack temperature and light control functions. Furthermore, the radicle cannot grow downwards smoothly, resulting in malformed germination morphology. The seeds cannot be fixed, and they are prone to shaking when the germination container is handled, which can damage the root tip and bud tip, affecting the observation and recording of the natural germination state of the seeds.

[0029] To overcome the above-mentioned defects, this utility model provides a seed germination box, including a box body and a box cover adapted to and connected to the box body. The side of the box body is provided with a plurality of elongated ventilation / water filling holes arranged side by side, and the bottom of the box body is provided with a plurality of circular ventilation / water filling holes. It should be understood that the ventilation / water filling holes arranged along the longest direction of the side of the box are elongated. It should be understood that the ventilation / water filling holes at the bottom of the box are regular-shaped round holes; It should be understood that the adapter connection refers to the connection between the two ends of the lid and the box body through a rotating shaft, so that the lid can be opened and closed.

[0030] The inside of the box is lined with different absorbent media from bottom to top; there is a gap between the box lid and the seed germination medium, the height of which is less than the diameter of the seed, so as to fix the seed.

[0031] In some embodiments, both the box body and the lid are made of transparent material.

[0032] In some embodiments, the absorbent medium includes a sponge and a velvet cloth.

[0033] For example, the velvet is absorbent velvet, square, one side length = 94 mm (for use with a sponge), and another side length = 98 mm (for use with a square petri dish); The sponge is square with a side length of 94 mm. One type has a thickness of 18 mm (suitable for fixing large-diameter seeds), and the other type has a thickness of 15 mm (suitable for fixing small-diameter seeds). In some embodiments, the transparent material is an acrylic plexiglass sheet.

[0034] For example, the germination box has the following dimensions: length × width × height = 100mm × 100mm × 25mm; A second aspect of this utility model provides a seed germination device, including the above-mentioned seed germination box and germination instrument; the seed germination box is placed upright in the germination instrument; wherein, the germination instrument includes a control base, a receiving box and a bottom liner; the receiving box is installed on the control base, and the bottom liner is placed at the bottom of the receiving box, and four seed germination boxes can be placed upright against the four side walls of the receiving box in the germination instrument.

[0035] In some embodiments, it also includes a light-blocking cloth, a water dropper, and a square petri dish; For example, the blackout cloth is a blackout fabric; For example, the hydration dropper is a Pasteur straw; For example, the petri dish is a square petri dish; Square petri dish: Length × Width × Height = 100mm × 100mm × 16mm; can be lined with moisturizing cloth; The blackout cloth is square: side length = 130mm; A third aspect of this utility model provides a seed germination method, which uses a germination device to perform germination, the process of which includes: 1) Soak the seeds in a petri dish until they absorb the nutrients and swell, then set aside. For example, the seeds can be any of the following: wheat, rice, corn, soybean, pea, mung bean, lettuce, or radish; the quantity is determined according to the experimental design. The germination rate is above 95% for all seeds.

[0036] 2) Set the germination temperature of the germination device; 3) Wash and absorb water from the absorbent media (sponge and velvet), squeeze out excess water, and place them in the germination box one by one, with the sponge at the bottom and the velvet on top, smoothing the velvet. Then arrange the swollen seeds on the velvet surface as designed, and close the lid. Finally, place the germination box upright in the germination device and wait for the seeds to germinate; 4) If water needs to be added during germination, take out the germination box and add an appropriate amount of purified water through the water inlet using a Pasteur pipette.

[0037] Example 1 A seed germination box, see Figure 1 The box includes a box body and a lid that is adapted to and connected to the box body. The side of the box body has multiple elongated vent / water filling holes arranged side by side, and the bottom of the box body has multiple circular vent / water filling holes. The box body and the lid are both made of transparent acrylic organic glass. The dimensions of the box body are length × width × height = 100mm × 100mm × 25mm. The ventilation / water filling holes arranged vertically along the longest direction of the side of the box are in the shape of long strips; The ventilation / water filling holes at the bottom of the box are regularly shaped round holes; The adapter connection refers to the connection between the two ends of the lid and the box body through a rotating shaft, so that the lid can be opened and closed.

[0038] The inside of the box is lined with absorbent sponge and velvet from bottom to top; a gap is left between the lid and the damp velvet, the height of which is less than the diameter of the seed. The velvet is square with a side length of 94mm; the sponge is square with a side length of 94mm.

[0039] The thickness of the sponge should be appropriate. For example, a thin sponge (15mm thick) should be used for larger seeds such as corn, peas, and soybeans, while a thick sponge (18mm thick) should be used for smaller seeds such as wheat, rice, and mung beans.

[0040] Example 2 A seed germination device includes a germination box as described in Example 1 and a germination instrument of model SXR01. Four germination boxes are placed upright at 90° angles together (see...). Figure 2 In the germination apparatus (see...) Figure 3 )middle.

[0041] Example 3: Seed germination using the germination device of Example 2. 1) Seeds absorb water Soak wheat seeds in a square petri dish to allow them to absorb water and swell. Rinse the seeds thoroughly with tap water, place them in the petri dish, add an appropriate amount of mineral water (not enough to completely submerge the seeds), gently shake the dish to moisten the seeds completely, cover, and leave to absorb water at room temperature. The temperature and time required for complete absorption vary depending on the type of seed; generally, it should not exceed 24 hours at 25℃.

[0042] 2) Germination treatment ① Setting the Temperature: First, place the liner at the bottom of the germination apparatus, carefully aligning it with the temperature sensor probe protruding from the center of the bottom. Add little or no purified water, ensuring it doesn't overflow the liner. Then, close the lid. Connect the power source using a USB power adapter for your mobile phone (not included). Press the "-" or "+" buttons to set the germination temperature to 25℃ or another experimental temperature. The instrument will then enter timing mode, alternating between the time and the set temperature display, and will begin heating (if the ambient temperature is higher than the set temperature, the instrument will only time the process without heating). The germination apparatus records time over a period of 99 hours (approximately 4 days). If the germination experiment is not yet complete, the temperature can be set again to restart. Additionally, if a power outage or other interruption occurs, the temperature should be reset immediately. It is best to attach a label to the upper left corner of the germination box indicating the start date; this will not affect the calculation of germination duration even during a power outage.

[0043] ② Seed Placement: Take a suitable sponge, soak it to absorb water, take a suitable piece of flannel, soak it in tap water, wear gloves, and squeeze out excess water with appropriate force. Then place the sponge into the germination box, cover the sponge with the flannel, smooth it out, and use tweezers to place the swollen seeds one by one. Close the lid, attach a label, and place the germination boxes upright at a 90° angle together into the germination machine. Up to four germination boxes can be placed at a time. Then close the germination machine lid and allow the seeds to germinate.

[0044] 3) Observation Records The recording period is 3 days, during which water may not be added. See [link to germination and growth process] for details. Figure 4 .from Figure 4 It is evident that the germination and growth process of wheat seeds is natural and morphologically typical. The morphology of roots and shoots during the growth process can be observed and measured without removing the seeds through the transparent germination box and germination instrument, ensuring the accuracy of the recorded results.

[0045] Four additional wheat seeds were taken and germination experiments were conducted using the same method. The germination process was recorded over four days, and the results are shown below. Figure 5 ,Depend on Figure 5 It can be seen that seeds placed upside down in the middle at the top germinate after one day, with the roots bending 180° downwards as soon as they emerge, while the buds only begin to clearly adjust their growth direction after two days of germination. By the third day of germination, the bud tips have completely adjusted their growth direction to grow upwards. At this point, if the germination box is rotated 90° clockwise and growth continues for one more day (to produce 4-day-old seedlings), all root tips adjust their growth direction downwards, while all bud tips adjust their growth direction upwards. The above experiment clearly shows that regardless of how the seeds are placed, the roots will always adjust their growth direction downwards, while the buds will always adjust their growth direction upwards.

[0046] Example 4 Seed germination experiments were conducted according to the method in Example 3, except that the seeds were replaced with radish, wheat, corn, pea, and mung bean seeds, respectively. After 4 days of germination, the radicle morphology was observed. Figure 6 .Depend on Figure 6It can be seen that the morphology and quantity of root hairs differ significantly among seedlings of different seeds. The radish seed in the image is the smallest, with long and dense root hairs in its seedlings; wheat and corn seedlings have short and dense root hairs; while pea and mung bean seedlings show significantly underdeveloped root hairs. Furthermore, the morphology and distribution of the root hairs also differ significantly. This indicates that the seed germination device of this invention allows for observation of the germination process of different seeds and facilitates comparison between different seeds, making it suitable for teaching experiments.

[0047] Comparative Example 1 Seed germination experiments were conducted using horizontally placed square petri dishes. Imbiosis was the same as in Example 3. After imbiosis, the seeds were placed directly in the square petri dishes, horizontally, and germinated at room temperature for 4 days. The results are shown below. Figure 7 It is evident that when seeds germinate in a horizontally placed container, the root tips are easily damaged due to the obstruction of downward growth. The morphology and distribution of root hairs are atypical and difficult to distinguish. Therefore, when observing the root tip structure under a microscope using this material, it is difficult to match it with the characteristic root tip structure diagrams in textbooks, which can easily lead to misunderstandings.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
