Corn and soybean strip-shaped interplanting and fertilizing composite precision seeder

The invention relates to a corn and soybean strip-shaped interplanting and fertilizing composite precision seeder. The combined seed and fertilizer drill comprises a sowing depth adjusting module, a ditching and soil covering module, a fertilizer and seed discharging module, a pressing adjusting module, a control module and a traction module, a machine tool is dragged by a traction frame module, the fertilizer and seed discharging module controls the sowing amount and the fertilizing amount according to the forward speed, and a seed discharging monitor monitors falling seeds through photoelectricity and controls the control module to control the control module. The front push rod motor pushes the parallel four-bar mechanism to adjust the vertical displacement of the furrow opener through the control module, the pressure sensor feeds back sowing depth downward pressure data to the control module in real time, the rear push rod motor pushes the rear parallel four-bar mechanism to adjust the vertical displacemen
