Micro seed dibbling device

The invention discloses a small seed dibbling device which comprises a pressing device, a buffering device and a collecting device, the pressing device is connected with the buffering device through a pressing handle, the buffering device is connected with the collecting device through a connecting port, the pressing handle pushes a first spring, the first pressing handle and a connecting handle to be pushed downwards through pressure, a push-pull device of the buffering device pushes a piston through downward pressure to be used for buffering the pressing speed, and then a fourth baffle is pushed to be opened and closed. The diameter of the collecting device is gradually reduced from top to bottom, and the diameter of a lower pipe opening is 0.05-0.3 cm. In a plant transgenic experiment, disinfected seeds with the diameter of 0.05-0.3 cm such as arabidopsis thaliana are put into the device, a small amount of sterile water is added to be uniformly mixed with the seeds, seed inoculation is completed by pressin
