The invention relates to an air-suction type high-density precision dibbler. The precision dibbler comprises two fixed plates (7), a movable plate (2) and a center shaft, wherein a cavity is formed by the fixed plates (7) and the movable plate (2), and is separated into a center negative pressure cavity (61), a left seed chamber (62) and a right seed chamber (63) by two seed extraction plates (5) which are arranged in the cavity and are provided with seed suction holes (51); the center shaft (3) is a hollow shaft with a negative pressure air extraction pipe and is provided with an air hole (31) communicated with the center negative pressure cavity (61); two rows of seed outlets (22) are formed in the movable plate (2) according to a left-right sequence; a dibbling nozzle (1) is formed in each seed outlet (22), and a seed channel (13) is formed between the dibbling nozzles (1) and the seed outlets (22) of the movable plate (2) and is inclined from outward to inward. Compared with the prior art, the air-suction type high-density precision dibbler has the advantages that more dibbling nozzles are distributed to realize high-density precision dibbling; and the air-suction type is adopted, so that the mechanism structure is simpler, and the reliability of working performance is greatly improved.
