the heavier the straw coverage was, the higher the blockage grade was. In order to archive a satisfied anti-blockage performance that do not impact no-till seeding, the maize straw length of straw should not be longer than 9.1cm. Working parameter test of the strip tillage seeder showed that travel speed and rotate speed significantly influenced blockage index and torque, while the travel speed become faster, the blockage index turned higher, and the torque turned up at fist then turned down at 4km/h, the higher the rotate speed was, the lower the blockage index was and the bigger the torque was, optimal working parameter was choose at 320r/min of rotate speed and 4km/h of travel speed.(Download PDF) (Export to EndNotes)
