The invention provides a non-destructive seeding method based on rapid adjustment of a seeding amount. A non-destructive seeding device based on the rapid adjustment of the seeding amount is used to implement seeding, a feeding control mechanism is arranged at the upper part of a box body, a seed brushing mechanism is arranged above a seeding control mechanism, the seeding control mechanism for controlling feeding is installed in the middle part of the box body, a seed protection mechanism is in contact with the seeding control mechanism, and a seed receiving cup is arranged under the box body; and at the same time, a left seed filling channel, a right seed filling channel, a seeding wheel seed filling channel, a seed storage area, a transition area, a seed filling area, a seed brushing area and a seed filling cavity capable of completing rapid adjustment of the seeding amount are formed in the box body through the above structure, and a left cavity cylinder and a right cavity cylinderin a lateral cavity component in the seeding control mechanism can communicate with the seeding wheel seed filling channel after being docked. The volume of the seed filling cavity is adjusted to realize rapid adjustment of the seeding amount, quantified seeds can be received into the seed filling cavity to avoid hard contact with the seed protection mechanism to cause mechanical damage to the seeds, so that the non-destructive operation is realized.
