Adjustable water and fertilizer integrated device with fixed-point fertilization function

The invention relates to the technical field of fertilization instruments, in particular to an adjustable water and fertilizer integrated device with a fixed-point fertilization function, which comprises a mounting frame, two hinged plates are rotatably mounted on each of the front and rear sides of the lower part of the mounting frame, a moving wheel is mounted on the lower part of each hinged plate on the mounting frame, and a connecting plate is mounted on the upper part of the mounting frame. A fertilization mechanism is arranged on the mounting frame and the connecting plate and used for quantitatively irrigating water and fertilizer, a height adjusting mechanism used for adjusting the height of the fertilization mechanism is arranged on the lower portion of the mounting frame, and the height adjusting mechanism is connected with a hinge plate on the mounting frame. The height of the fertilizing mechanism is adjusted through the height adjusting mechanism so as to be suitable for ridges with different he
