Steep hillside orchard fertilizing system and control method thereof

The invention discloses a steep hillside orchard fertilizing system and a control method thereof. The steep hillside orchard fertilizing system comprises a water source project, a dosing system, a power device, a water transmission pipe network and a spraying apparatus. The control method includes steps of feed liquid preparation, filtering, starting of an irrigation pressure device, feed liquid spraying, cleaning of fertilizer distributing system and the water transmission pipe network, closing of the power device and the water valve. Through the dosing system and the power device, fluid material is pumped to every spraying zone of the steep hillside orchard through the water transmission pipe network; an outlet valve of every spraying zone is linked with a spraying hose and a spray gun so as to irrigate fruit trees in the zone. The system is applicable to the steep hillside orchard, small in investment and has advantages of effectively saving human source, significantly reducing labor intensity and producti
