摘要：
In order to meet the requirements of planting techniques of dry-land corn whole plastic-film mulching on double ridges in northwest China, to solve the problems about picked film and tore film and kind of holes with seedlings dislocation caused by the traditional film seeding machine, a direct insert corn precision hill-seeder with whole plastic-film mulching on double ridges was designed. It adopted cam-crank connecting rod mechanism and motion amplification mechanism to control the hole-former sowing and force open in fixed-point. Simulation analysis and field experiment showed that when the direct insert corn precision hill-seeder was planting operation with whole plastic-film mulching on double ridges, the hole-former horizontal velocity component was zero in sowing period and excavating period, the planting distance could be adjusted within a certain range, the arrangement of the soil hole and the hole-former motion trajectory were all reasonable, which met the requirements of agronomic techniques of dry-land corn furrow seeder with whole plastic-film mulching on double ridges.
