The invention provides a hybrid power system of a hybrid power tractor and a control method of the hybrid power system. The hybrid power system comprises an engine, a motor, a transmission system, a hydraulic transmission device, a clutch assembly, a transmission device and lifting equipment. The engine and the motor are respectively connected with the transmission system, and the output end of the transmission system is a main power output end and a PTO output end; the PTO output end is connected with the input end of the hydraulic transmission device, the output end of the hydraulic transmission device is connected with the lifting equipment, and the main power output end is connected with the lifting equipment. And continuously variable transmission ratios are provided between the PTO output end and the lifting equipment, between the main power output end or/and the motor and the lifting equipment, and between the PTO output end and the main power output end or/and the motor and the lifting equipment. The device can be suitable for various working conditions that a tractor drives lifting equipment.
