The invention discloses a farmland soil parameter measuring trolley which comprises a trolley body and a soil parameter measuring system installed on the top of the trolley body. The soil parameter measuring system comprises a combined soil parameter measuring device; the combined soil parameter measuring device comprises a sliding table fixing frame, a first ball screw sliding table, a first stepping motor connected with a lead screw of the first ball screw sliding table, a measuring connecting plate installed on a sliding block of the first ball screw sliding table, a pull pressure sensor and a soil moisture content measuring groove plate, wherein the pull pressure sensor and the soil moisture content measuring groove plate are both fixed to the bottom of the measuring connecting plate. The cone measuring device is connected with the tension and pressure sensor, and the soil moisture content sensor and the thin film pressure sensor are installed at the groove bottom of the soil moisture content measuring groove plate. A combined soil parameter measuring device and a compartment surface flatness measuring device are integrated together, parameters such as soil firmness, a friction angle, soil moisture content and compartment surface flatness can be obtained through one-time field measurement, and various soil parameter measuring devices are integrated.
