Provided is a precision sowing device for rice pot seedling raising. The device includes a rack, a seed storage mechanism, a seed suction mechanism, and a driving mechanism. The seed suction mechanism includes a seed suction cylinder, and a circulation assembly. The sowing mechanism includes a sowing cylinder rotatably arranged on the rack, and multiple sowing troughs corresponding to multiple suction nozzles one by one are arranged on an outer wall of the sowing cylinder. The driving mechanism is used to drive the seed suction cylinder and the sowing cylinder to rotate in the same direction clockwise or counterclockwise around axes thereof, such that the suction nozzle and the sowing trough are opposite to each other and have opposite movement trends, and seeds on the suction nozzle can be scraped into the sowing trough by an inner wall of the sowing trough.
