The invention discloses a multi-rotor unmanned aerial vehicle variable spraying system, wherein a power source is fixed on an upper support plate; a pesticide box and an electric gear pump are fixed on a lower support plate; sprayers are symmetrically mounted below rotors at two sides of an unmanned aerial vehicle frame through fixed rods; a liquid outlet of the pesticide box is connected into a liquid inlet of the electric gear pump, and a liquid outlet of the electric gear pump is connected into liquid inlets of the sprayers at the two sides of an unmanned aerial vehicle through a tee joint. According to the system provided by the invention, the sprayers are mounted below the rotors, the defect that ultra-low-volume spraying is liable to drift is avoided, and the penetrability of droplets is enhanced; by adopting the way that centrifugal atomizing spraying is combined with the electric gear pump, the phenomenon that the ultra-low-volume spraying is unstable and incoherent is overcome, through the manner of switching the sprayers and adjusting the rotating speed of a pump motor, the variable spraying is realized, the spraying system is applicable to prevention and cure needs of different crops, the loss of pesticide liquid is reduced, a remote controllable module is additionally arranged, the spraying volume can be automatically adjusted according to the flight speed of the unmanned aerial vehicle, and the waste of resources is reduced.
