The invention discloses an intelligent tree infusion and irrigation system, and belongs to the technical field of forestry and agriculture automation. The intelligent tree infusion and irrigation system can infuse trees automatically according to different conditions. A detection device is used for detecting healthy growth conditions of the trees, and comprises an electricity-conducting device, asoil acidity detector, a temperature detector, a camera and a beam lamp. A box for infusing the trees is placed on a branch, and is filled with three solutions, including a nutritional solution, a growth solution and an insecticide solution. Infusion modes include drop irrigation and spray irrigation. The detection device detects specific conditions of the trees and sends the specific conditions to a single chip microcomputer, the single chip microcomputer sends different commands according to different conditions for infusion, health conditions of the trees can be sent to a computer control side through a communication module to be checked, and infusion can be operated manually on the computer control side. The system has the advantages that full-automatic operation and unmanned attendance are achieved, substantial labor can be saved, and the trees can be managed scientifically.
