The invention relates to the technical field of planter equipment, in particular to a spacing-adjustable soybean and corn strip-shaped composite planter which comprises a traction frame, a seed-metering device, a seed-metering pipe, a fertilizer applicator and a fertilizer applying pipe, a sliding rail is arranged on the traction frame, a mounting seat is slidably mounted on the sliding rail, the seed-metering device and the fertilizer applicator are both arranged on the mounting seat, and the fertilizer applying pipe is arranged on the mounting seat. A seed metering pipe and a fertilizer applying pipe are arranged on the seed metering device and the fertilizer applying device, two guide rails are arranged on the mounting seat, guide pipes are arranged in the two guide rails, the two guide pipes are respectively sleeved on the seed metering pipe and the fertilizer applying pipe, each guide pipe is divided into an insertion part, a hose and a sliding part, and the insertion part is connected with the sliding part through the hose. The insertion part is connected with the sliding part through the hose, so that the guide pipe can rotate after being inserted into soil, the guide pipe is prevented from pulling the film, the film is prevented from being damaged greatly, the film is prevented from being lifted to generate bumps, the heat preservation, moisture preservation and weed suppression effects of the film are guaranteed, and planting benefits are guaranteed.
