Fruit tree infusion device

The invention relates to the technical field of trees planting, particularly to a fruit tree infusion device comprising a fixing holder and an infusion structure. The infusion structure comprises a liquid storage box. A pressure bump is mounted above the liquid storage box and connected with the same through a pressure pipe. An infusion outlet is formed in the bottom of the liquid storage box and provided with a valve. A plurality of infusion pipes are connected to the infusion outlet. The tail ends of the infusion pipes are connected with infusion needles. Due to the infusion pipes, infusion can be simultaneously performed to a plurality of fruit trees and can be performed to a fruit tree by the infusion pipes to cause rapid infusion speed. Besides, with the pressure device mounted on the fruit tree infusion device, infusion speed is more rapid. The liquid storage box is provided with an air exhausting outlet and a liquid inlet pipe to firstly vacuumize the same, then the liquid is exhausted by the liquid inlet pipe, and accordingly operational convenience is achieved.
