NaeUe with equipment and seedling planting method of no-till field

摘要

PURPOSE:To plant seedlings in aligned and erected state and to prevent troubles caused by straw dust, weed, etc., by thrusting a furrow-opening tool having a working width slightly narrower than the width of a transplantation claw into a non-tilled field to a depth deeper than the lowering limit of the transplantation claw and using a specific furrow-opening cutter as a furrow-opening tool. CONSTITUTION:A furrow is formed by thrusting a furrow-opening tool having a working width slightly narrower than the width of a transplantation claw 12 into a non-tilled field to a depth deeper than the lowering limit of the transplantation claw 12. The transplantation claw 12 holding the rootstock of seedling is inserted into the furrow from above and the rootstock of the seedling is pushed into the furrow lower than the tip end of the transplantation claw 12 by a pushing claw 12a near the lowering limit of the transplantation claw 12 to complete the transplantation of the seedling. A seedling-transplanting furrow-opening cutter 41 having the following structure is used as the furrow-opening tool. A number of teeth 47... are protruded from the outer circumference of a disk and these teeth 47 are alternately bent right and left to form a set of crosscut teeth and, at the same time, to apply a sweepback angle to the teeth. The outer width of the teeth 47 is made to be slightly narrower than the outer width of the transplantation claw 12.
