Development and Experiments of 2BLZ-2 Ridge-Rolling Precise Sowing Machine

2BLZ-2 suppressed precise sowing machine to be used on ridge of land equipped with combined profile modeling moving wheels merges with gaging function into an organic whole. It adopts precision maize seed metering device of step-inner-cell sowing device and can complete precise sowing. Two groups of springs are installed in it so as to insure the sowing in uniform and make the suppressing strength changeable. The field experiments and analyses of the technical function have proved that this sowing machine has high working quality and reliable technical function.
