An agricultural unmanned aerial vehicle comprises a center frame (10), a control module, a left vehicle arm set (20) and a right vehicle arm set (30). The left vehicle arm set (20) and the right vehicle arm set (30) each comprise a front vehicle arm assembly (21), a rear vehicle arm assembly (23) and a middle vehicle arm assembly (22). The middle vehicle arm assembly (22) comprises a first rotor wing assembly (221). The front vehicle arm assembly (21) comprises a second rotor wing assembly (211). The rear arm assembly (23) comprises a third rotor assembly (231), and in the output direction ofdownward-pressing wind fields of the left arm set (20) and the right arm set (30), the height of a rotating plane where the first rotor assembly (221) is located is smaller than that of a rotating plane where the second rotor assembly (211) and the third rotor assembly (231) are located. The agricultural unmanned aerial vehicle further comprises a spraying system (50), and the spraying system (50)comprises a sprayer assembly (51). The control module is used for controlling the left vehicle arm set (20) and the right vehicle arm set (30) so as to adjust the flight attitude of the agriculturalunmanned aerial vehicle, and the left vehicle arm set (20) and the right vehicle arm set (30) output the downward-pressing wind field in the direction of the sprayer assembly (51).
