[0002] During the sowing process of potted experiments, the depth of seeds sown into the substrate has an important influence on the germination rate, germination time and seedling morphology of the seeds. If the sowing is shallow, the soil is prone to loss of moisture and drought, and the seeds are difficult to reach the conditions for germination and lose their germination ability, or they germinate reluctantly and form weak seedlings. On the contrary, if the sowing is deep, even if the soil moisture is good, the seeds can fully absorb water and germinate, but the seeds cannot get enough oxygen or consume more nutrients from germination to emergence, which eventually leads to a decrease in the germination rate. It is necessary to use a sowing hole depth measuring device to measure the sowing depth to ensure the accuracy of the sowing depth.

[0003] However, the structure of traditional seeding hole depth measuring devices is too complicated and the operation is too cumbersome, and the accuracy is not high, which affects the accuracy of the seeding depth measurement structure. In this regard, in order to solve this technical problem, the present application proposes a seeding hole depth measuring device. Utility Model Content
