Trace fertilization device for mulberry planting

The utility model belongs to the technical field of fertilization devices, particularly relates to a micro-fertilization device for mulberry planting, and aims to solve the problems that the fertilization amount of a plurality of existing spraying devices is difficult to control in the fertilization process, a pushing device is required to move for fertilization during fertilization, and the existing devices are not provided with damping devices, so that when the pushing device moves forwards, the fertilizer application amount is difficult to control. According to the technical scheme, the device comprises a box body, a motor is fixedly mounted on one side of the box body, one end of a rotating shaft is fixedly connected to an output shaft of the motor, and the other end of the rotating shaft extends into the box body and is rotatably mounted on the inner wall of one side of the box body. The fertilizer applicator is simple in structure and reasonable in design, the angle of the sprayhead can be swung in a re
