FIELD: agriculture.
SUBSTANCE: method includes bending down, crimping, shredding a shrub and milling soil. After a tractor aggregate bending down, the shrub on the strip between the chain tracks is crushed while simultaneously milling the topsoil to the depth of a carriage running track. Shrub compressed by the chain tracks is milled into strips to the depth of its root zone. From the inner walls of the strips, slits are cut to the depth below the arable layer, they are filled with a ground mass between the chain tracks, after which the soil between the chain tracks of the tractor aggregate is also milled to the depth of the root layer of the shrub with overlapping slits in width. Device includes a tractor aggregate with knife rolls, containing a frame with two sections of knife rolls. Two knife rolls of the front section are installed symmetrically across the chain tracks of the tractor aggregate running track carriage. Intermediate knife roll of a smaller diameter is placed between them, and behind it, a counter knife corresponding to the front section, provided with milling chisel ploughs, installed symmetrically with respect to the inner ends of the front section knife rolls, and a screw with two oppositely directed branches. Milling chisel ploughs are equipped with bunkers, the receiving parts of which are associated with the discharge branches of a screw. Width of a knife roll of the rear section and the corresponding shear knife overlaps the width of the milling chisel ploughs.
EFFECT: inventions allow to reduce the energy intensity of processing of bushy fields, provide better conditions for maintaining constant humidity in the arable horizon, accelerate the decomposition of wood residues in the soil and prevent secondary overgrowing of fields.
