METHOD FOR PREPARATION OF SEED BED

摘要

The invention relates to agriculture, in particular to operations of soil processing in presowing period of growing agricultural crops and sprigs. The essence of the method is characterised in the following: seed bed is prepared in several steps including soil processing with a device that comprises tilling hoes and/or discs and at least one soil cultivating drum made as a helical element with right or left turn slope. The helical element is embodied with at least one break and consists of at least one rolling surface, at least one mulching surface and tilling elements, wherein the spiral part near the break is used as a tilling element. After soil processing with tilling hoes and/or discs by the soil cultivating drum for one pass of the device the soil is mulched, displaced in axial direction of the spiral turn slope, mixed with simultaneously combing of weeds out to the soil surface and rolled by the rolling surface of the spiral of the soil cultivating drum, thus ensuring an intensive self-cleaning spiral from soil and vegetable residues by providing the spiral autovibration caused by the use of the spiral with at least one break. The technical result provides improved quality of seed bed preparation with simultaneous intensive combing of weeds out to the soil surface and self-cleaning of the working surface of the soil cultivating drum.
