The invention discloses a pesticide spraying system for a single-rotor unmanned plant protection helicopter, which belongs to the technical field of plant protections of agricultural unmanned helicopters. The system comprises a pesticide box, wherein nozzles are connected with the pesticide box through pipelines and valves; the two nozzles are arranged on the two sides of a helicopter body; the connecting line of the two nozzles is intersected with a vertical axis of a main rotor in a cross-shaped way; and the positions of the two nozzles in a horizontal direction are on a connecting line section is made between the boundary of a downward spiral airflow field of the main rotor and the outermost side of the helicopter body in the horizontal direction, wherein the nozzles are positioned in the middle position of the line section or fall within a range extending less than 20% of the line section length towards the two sides with the middle position as the midpoint. According to the pesticide spraying system for the single-rotor unmanned plant protection helicopter, disclosed by the invention, as the mounting positions of the sector-shaped nozzles are determined according to the boundary of the downward spiral airflow field of the main rotor, hoisting effects of the main rotor and a tail wing of the unmanned helicopter on spraying sectors generated by atomizing of the nozzles can be effectively avoided; and as pesticides are deposited on a target in an oriented way, the pesticide utilization rate is greatly increased.
