Specifically, the seeds are disturbed to be in an orderly boiling state by the seed disturbing mechanism so as to reduce the resistance among the seeds, then the pressure difference is formed between two sides of a shaped hole on the seeding plate by the airflow, the seeds are adsorbed on the seeding plate, the seeds rotate along with the seeding plate to separate from densely-piled populations, and the seeds are discharged by single seeds at the outlet of the seeding device. If the link fails, the subsequent links cannot be compensated, and holes and broadcast omission are inevitably caused. In a different crop compound planting mode (such as compound planting of corn and soybean), different crops can be planted in adjacent seed rows, but the problems that the heights of the crops are different and the illumination and the soil fertility are mutually influenced easily occur.
