Novel fruit tree fertilizer applicator

A novel fruit tree fertilizer applicator belongs to the field of fruit tree fertilizer application and aims to solve the problems of insufficient insertion depth and small fertilizer application range of a fertilizer applicator. The main pipeline is a cylindrical round pipe, the top of the main pipeline is inserted into the connecting elbow, a sealing tape is wound at the joint of the main pipeline and the connecting elbow, the rear end of the connecting elbow is connected with a valve, and an auxiliary rod is welded to the outer side of the bottom of the main pipeline; the auxiliary pipelines are welded to the bottom of the main pipeline, and the two auxiliary pipelines are symmetrically arranged; the needle-shaped bottom of the auxiliary pipeline of the novel fruit tree fertilizer applicator can reduce the resistance when the auxiliary pipeline is detached into soil, the inclined top of the auxiliary pipeline can reduce the energy loss in the process of conveying liquid fertilizer from the main pipeline to
