[0002] Seed germination experiments are experiments that observe and study the germination process of seeds through artificial manipulation and control of conditions. They aim to understand which factors affect seed germination, such as water, temperature, light, and soil type. Through this experiment, we can understand the growth patterns of plants and guide practical agricultural and horticultural activities.

[0003] Currently, the commonly used tools for seed germination experiments are petri dishes or germination boxes. Filter paper is placed in the petri dish, and culture medium is added to conduct the seed germination experiment. During the seed germination process, the number of germinated seeds needs to be recorded every day. Existing conventional experiments require counting all germinating seeds every day, resulting in repeated counting, high time consumption, and a large workload, which is not practical. Therefore, a device is proposed to simplify the counting of seeds in seed germination experiments to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a device for simplifying seed germination counting experiments, comprising a petri dish 1 for seed germination cultivation, a top cover 2 adapted to the top of the petri dish 1, both the petri dish 1 and the top cover 2 being made of transparent material, such as glass or acrylic, with counting paper 5 on the upper part of the top cover 2 for counting the daily germination of seeds, each record being marked with a different colored pen for easy differentiation and statistics, a cultivation rack 3 placed in the middle of the petri dish 1 for placing filter paper 4, and a circular opening at the center of the filter paper 4 for laying on the cultivation rack 3.

[0031] Furthermore, the upper surface of the filter paper 4 is provided with a positioning grid 41, which is used to distinguish the seed position. The upper surface of the filter paper 4 is provided with multiple labels 44, which are used to assist in counting. The front of the top of the filter paper 4 is provided with a first arrow 43, which is matched with the second arrow 53, and is used to assist in the rapid positioning of the counting paper 5. The front, back, left and right sides of the filter paper 4 are all provided with a first positioning hole 42.

[0032] Furthermore, the counting paper 5 can be a transparent plastic sheet to facilitate timely observation of germination and make recording easier. The upper surface of the counting paper 5 is provided with a counting grid 51 to assist in recording germination and facilitate data statistics. The front of the top of the counting paper 5 is provided with a No. 2 arrow 53 to assist in positioning the counting paper 5 and the filter paper 4. The diameter of the counting paper 5 is the same as that of the filter paper 4. The number and size of the positioning grid 41 and the counting grid 51 are the same. The front, back, left and right sides of the counting paper 5 are provided with No. 2 positioning holes 52 to assist in positioning the positioning post 21.

[0033] like Figure 2 As shown, the culture rack 3 includes a culture plate 31, on which filter paper 4 is placed. A limiting groove is formed in the lower part of the culture plate 31, and a positioning rod 11 is movably connected to the limiting groove. It is used to position the culture rack 3 when it is placed in the culture dish 1. A pull rod 33 is fixedly connected to the top of the culture plate 31 to facilitate the removal of the culture rack 3. Limiting blocks 32 are fixedly connected to the front, back, left and right sides of the top of the culture plate 31 to help position the filter paper 4. Multiple culture grooves 311 are formed in the top of the culture plate 31 to restrict the seeds to a certain extent and prevent the seeds from shifting during placement and growth, which would affect the counting. The position of the culture grooves 311 is matched with the position of the number 44 on the filter paper 4.

[0034] Specifically, multiple positioning rods 11 are fixedly connected to the bottom of the inner wall of the petri dish 1, which are used to position the filter paper 4. A limiting ring 12 is fixedly connected to the top of the petri dish 1, which is used to connect the top cover 2. Positioning blocks 13 are fixedly connected to the front, back, left and right sides of the outer wall of the limiting ring 12, which are used to limit the top cover 2. Positioning posts 21 are fixedly connected to the front, back, left and right sides of the top of the top cover 2, which are used to position the counting paper 5. The second positioning port 52 is movably connected to the positioning post 21. Positioning grooves 22 are opened on the front, back, left and right sides of the inner wall of the top cover 2. The positioning blocks 13 are adapted to the positioning grooves 22 and are engaged with the positioning grooves 22.

[0035] Working principle: In each experiment, filter paper 4 is laid on culture plate 31, so that the limiting block 32 passes through the first positioning port 42. Then, culture rack 3 together with filter paper 4 is placed in culture dish 1, so that positioning rod 11 is inserted into the limiting groove at the bottom of culture plate 31. Then, water or nutrient solution is sprayed to make filter paper 4 reach the required humidity. When filter paper 4 is moist, it can better adhere to the surface of culture plate 31. Then, the experimental seeds are placed at the marked position on filter paper 4, that is, at the number 44 on positioning grid 41. Then, the top cover 2 is covered, so that positioning block 13 is inserted into positioning groove 22.

[0036] During a routine germination experiment, when a seed germinates, take a piece of counting paper 5 and place it on top of the top cover 2, so that the positioning post 21 passes through the second positioning opening 52. Align the position of the second arrow 53 on the counting paper 5 with the direction of the first arrow 43 on the filter paper 4. Record the specific location of the germinated seed within the counting grid 51 of the counting paper 5. Different colored pens can be used to distinguish the daily records. At the same time, record the number of germinations in the experimental record book. In this way, only newly germinated seeds are recorded each day, without having to repeat the recording of previously germinated seeds, which can greatly reduce working time and workload.

[0037] At the same time, it is easier to calculate germination potential and germination index data. Furthermore, based on the germination location, it can be further determined which seeds germinate first when needed, and the daily growth of the radicle can be measured.

[0038] When the data recording is complete and the experiment is finished, and the filter paper 4 needs to be removed, open the top cover 2, and then use the pull rod 33 to remove the culture rack 3 from the culture dish 1, and then remove the filter paper 4 from the culture rack 3.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
