PROBLEM TO BE SOLVED: To provide an injection device for a nutrient solution for garden trees capable of reducing waste of the nutrient solution. SOLUTION: A shale 1 provided with an internal upper chamber 1a and a lower chamber 1b, two attachment means for attaching the shale 1 to a garden tree having a different diameter by being fixedly connected to an outer portion of the shale 1, and a shale 1 A sealing means attached to the front end of the feeding bag for taking out and arranging the nutrition bag, and a micro pressure means attached to the inside of the upper chamber 1a to apply a slight pressure to the drip solution in the feeding bag downward. , A drip tube connected to the lower screw of the nutrition bag and sequentially penetrating the upper chamber 1a and the lower chamber 1b and extending to the outside of the shale 1, and attached to the inside of the lower chamber 1b, on the outside of the shale of the drip tube. A nutrient solution injection device comprising a telescopic means for adjusting the length of a portion and a positioning means for fixing a portion of the drip tube on the outside of the shale, which is fixedly attached to the lower end of the shale 1.
