The invention relates to an electric drive system of a hydrogen-electricity hybrid power tractor and a control method. The electric drive system comprises a hydrogen fuel cell and a power battery pack which are main power sources of the hybrid power tractor, and a double-motor electric drive system composed of a first motor, a second motor and a transmission system. The energy utilization rate of the power supply system of the hydrogen-electricity hybrid power tractor is optimized by setting a power battery pack SOC maintenance type control method which takes the output power of a hydrogen fuel cell as a leading mode; by arranging the dual-motor driving system, a multi-mode driving mode can be achieved to adapt to operation in a complex environment, and the dynamic property and economical efficiency of the tractor are improved.
