The invention relates to a reversing device and a multifunctional agricultural production system. The reversing device comprises a traveling module, a rotating module and a transition module. The traveling module can travel on a specified path; the rotating module can rotate at the topo of the traveling module; the transition module is arranged above the rotating module and rotates with the rotating module. The multifunctional agricultural production system comprises rail sets arranged on a field and an operating apparatus erected on the rail sets and capable of moving along the rail sets; therail sets include at least one first rail set and at least one second rail set arranged at the tail end of the first rail sets; the second rail set is identical with the first rail set in structure;the reversing device is arranged on each second rail set. The rail erection mode is utilized herein; operating can be carried out just by moving the operating apparatus above a crop planting land; efficient high-intelligent full-automatic operations, such as tilling, seeding, fertilizing, pesticide spraying, harvesting, collecting, and transporting, can be performed; workload of equipment is reduced; the intelligent operating apparatus can operate smoothly.
