[0002] The importance of corn as one of the important food crops is self-evident. Therefore, with the development of science and technology, mechanized sowing of corn can greatly reduce labor and labor expenses. In the process of sowing corn seeds, different sowing environments and the yield of corn seeds will also affect the germination rate of corn seeds. In order to improve the germination rate of corn sowing, it is necessary to simulate the sowing environment before sowing and conduct germination rate experiments on the selected good-quality corn seeds, so as to effectively improve the growth effect and yield of corn in the later stage.

[0003] However, the existing corn germination rate test box still has certain defects when used;

[0004] For example, a sweet and sticky corn germination rate experimental equipment for different planting environments proposed in application number CN202410088880.6 includes a breeding box, a breeding pot is fixedly sleeved in the breeding box, water is poured between the breeding box and the breeding pot, a plurality of holding slots for placing soil are provided in the breeding pot, a thermometer and a hygrometer are inserted in the soil of each holding slot, a positioning plate is fixed on the top of the side wall of each holding slot, a protective cover is movably connected to the breeding box, the protective cover is made of transparent glass material and has a plurality of ventilation holes, which is convenient for observing the germination rate and bud potential of the sweet and sticky corn in the breeding pot, and is convenient for sowing corn through a sowing device, without manual sowing, and without leveling the soil layer directly above the seeds, and at the same time, the sowing depth is accurately controlled by the sowing device, which solves the problem of manual sowing and different seed burying depths, and can better obtain the experimental data of corn seed germination rate and bud potential. In actual use, there are still the following problems:

[0005] The experimental equipment ensures the humidity of the soil in the breeding pot by pouring water between the breeding box and the breeding pot. However, this moisturizing method can only ensure the overall humidity inside the breeding box, and it is easy to have uneven humidity. It is impossible to adaptively irrigate the soil in the breeding pot during the experiment, so it is impossible to ensure sufficient humidity of the soil, and then it is impossible to ensure the effective germination of corn seeds, which reduces the use effect;

[0006] In the experimental equipment, the breeding pots are placed inside the breeding box, and the subsequent operation of taking out the breeding pots is inconvenient.

[0007] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0008] In view of the above problems, an innovative design was carried out based on the original corn germination rate test box with comparative experiment function. Summary of the invention
