The present invention relates to the field of agricultural machinery, and particularly relates to a farmland bar-inserting machine. The farmland bar-inserting machine comprises a machine body, a pair of moving apparatuses, a bar-inserting apparatus, and a bar feeding apparatus. The machine body comprises a machine plate and a pair of mounting racks, wherein the mounting racks are slidably connected to the machine plate, and each moving apparatus is correspondingly arranged on a mounting rack. The machine plate is provided with a notch and an introduction port in communication with the notch, and the bar-inserting apparatus is arranged near the notch. The bar-inserting apparatus comprises a stretching apparatus and a fixture, wherein the stretching apparatus is connected to the machine plate, and is connected to the fixture so as to allow the fixture to move along the gravity direction. The bar feeding apparatus arranged near the introduction port comprises a material collection case and a pusher, wherein the material collection case and the pusher are both connected to the machine plate. The above farmland bar-inserting machine can plunge the to-be-inserted bar materials into the field ridge from the machine body by using the machine body, and the moving apparatus, the bar-inserting apparatus, and the bar feeding apparatus arranged on the machine body, so that mechanical insertion of the to-be-inserted bar materials can be achieved, the manual mode is replaced, and the bar-inserting efficiency is greatly improved.
