Description

Technical Field

[0001] The utility model relates to a seed observation device, in particular to a plant seed germination observation device, belonging to the technical field of seed inspection. Background Art

[0002] Seed germination is the process by which the seed embryo changes from a relatively static state to a physiologically active state and grows into a nutritious seedling. Germination detection of plant seeds can help grasp the germination rate of plant seeds and achieve improved varieties and quality standardized planting of plant seeds. Therefore, before sowing plant seeds, it is often necessary to observe the germination status of the seeds.

[0003] In the prior art, there is a seed germination plate device that is easy to observe and measure, such as the one disclosed in announcement number CN218587591U. The device is easy to observe and effectively prevent the position of the seeds from moving, while ensuring that the seeds are evenly distributed, ensuring that the seedlings and root systems of the seeds grow independently and without cross-entanglement, and is easy to observe, compare, and measure, ensuring sufficient but not excessive water supply, easy to operate, saving manpower, simple structure, low manufacturing cost, low later maintenance cost, and good applicability. However, in actual use, although the existing device can ensure that the seeds are evenly distributed, the seeds are germinated on the same complete bottom plate. If mold grows on the seeds in a certain area during the germination period, it will cause other related The seeds in the neighboring areas will also be affected, which will be detrimental to the normal germination and growth of the seeds. Secondly, the conditions required for seed germination are water, light and oxygen. If sufficient oxygen cannot be guaranteed during the germination period, it will affect the normal germination of the seeds. However, if the seeds are directly exposed to the air for germination, it will easily attract some flying insects or birds, and if some debris falls on the seeds, it will also block the seeds, making the blocked seeds unable to receive sufficient light. In addition, although the existing device can realize the germination of seeds and then observe them, the germination of the seeds sown is also related to the sowing density, and the existing device does not take into account the observation of the germination of the seeds under different densities.
