A motor-driven single-seed-ejection sowing device includes a housing, a seed metering roller, a seed brush, a seed metering mechanism and a power mechanism. The housing includes a power compartment and a seed compartment. The surface of the seed metering roller includes seed grooves having spaces for accommodating a single seed. The seed metering mechanism includes a spring, a striking tube, a piston and the piston tube. The piston and the piston tube are arranged for axial movement inside the striking tube. The power mechanism includes a control unit and a drive unit. The control unit includes the motor, the drive panel, the Hall sensor and the magnet. The magnet is set on the striking tube. The Hall sensor and the drive panel are connected to the motor, and the motor drives the seed metering roller and seed metering mechanism by the drive unit.
