The farmland ecological environment monitoring system structurally comprises a base, a sampling monitoring device, a display device, a supporting plate and a device shell. The base is arranged at one side, provided with the sampling monitoring device, of the device shell and, together with the device shell, forms an integrated structure by means of mechanical welding. The sampling monitoring device is vertically embedded into the center of the end surface of the device shell; the supporting plate is mounted on the right vertical surface of the end surface with the sampling monitoring device of the device shell; and the display device is perpendicular to the upper side end surface of the device shell and is movably connected with the device shell in a bolt fixing manner. The system has the beneficial effects that: Because of a conical structure being formed by a triangular plate on a resolver with a butterfly frame as a central supporting point and having a sharp front part and an expanded rear part, agglomerated soil can be separated rapidly by using rotating as a power medium andcombining a rhombic opening formed in an upper triangular plate body, so that take-out work after sampling becomes convenient; and after reduction of agglomeration, the monitoring difficulty can be reduced, and data are more accurate.
