Chinas traditional orchard is the dense planting percent, model mainly used in the production of planting, as the growth of the tree fruit trees, a lot of old orchard in the canopy closure phenomenon, orchard intemal space is narrow, closed, poses challenges to the orchard to realize mechanization operation.More traditional orchard pesticide machinery in our country at present stage is given priority to with knapsack sprayer,hand-held spray machine, working efficiency is low, the pesticide effect is poor, serious bodily injury to the operator to administer.
