TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, and particularly relates to a seeding machine. BACKGROUND

[0002] In modern agricultural production, seedling raising is a key initial link of crop planting. When facing a region with poor soil, in order to provide a good growth environment for seeds, the currently commonly used method is to pre-lay a layer of substrate on the soil, then perform seed planting, and finally cover the substrate again on the top of the seeds. However, the existing seedling raising mode has many problems when performing the above series of processes.

[0003] In the traditional substrate laying process, workers usually use a shovel to uniformly spread the substrate in the planting area, and then plant seeds on the constructed substrate. The above substrate laying process not only consumes a lot of manpower, but also is difficult to guarantee the uniformity of the thickness of the laid substrate, which will adversely affect the subsequent germination and growth of the seeds. In large-area seedling raising, the time cost required by the above substrate construction is too high, which restricts the scale and progress of agricultural production. SUMMARY
