The present invention relates to a fertilizer injector, the fertilizer used for crops, after the crop is grown, the method of scattering is less effective to the crop and solved the problem that occurs when the rain occurs to put the quantitatively adjacent to the roots in the ground Developed to allow the operator to work quickly in a comfortable position； Blades having a pair of semi-conical shape formed so as to be conical when the symmetry close to each other and the upper end is opened by a hinge, and the upper end is fixed to the upper end of the blade and extended upward A main body comprising a pair of shovels forming a T shape by a handle bar extending to the shape of the T-shape； One side extends up and down long and the first bag seating groove is inserted into the bottom of one of the shovel, and the first fixing pin for rotatably fixing the shovel penetrating in the front and rear direction is inserted into the first bag seating groove； And a discharge pipe protruding downwardly on the bottom surface adjacent to the first bag seating groove, and an input pipe protruding upwardly on an upper surface opposite to the discharge pipe, and an opposite side to the surface on which the first bag seating groove is formed. A fixed box having a pipe shape having a rectangular cross section to be opened； One side is inserted into the fixed box, the other side is extended up and down so that one of the bottom of the shovel is inserted into the second bag seating groove and the front and rear direction so as to rotate the shovel bag inserted into the second bag seating groove A fertilizer dispenser comprising a sliding box having a second fixing pin for fixing and having a fertilizer distribution hole to penetrate up and down to coincide with an input tube when the pair of handle bars are opened and to coincide with an outlet tube when it is narrowed. Wow； One end has a flexible tube coupled to the input tube of the fertilizer dispenser and the other end is connected
