FIELD: agriculture.
SUBSTANCE: method involves preliminarily plowing root layer by deep cutting of soil layer without turning and deformation thereof by means of, preferably, flat U-shaped working tool; separating soil and separating rootstocks and roots during second passage along track of previous working tool by lifting undercut layer with the help of inclined lifters and by providing periodic impacts upon lifted layer from the bottom to the top by means of teeth of rotating rotor, with following moving of licorice roots and rootstocks onto surface of tilled soil strip and of soil aggregates and ground to the initial position; providing soil strip of 1.9-2.2 m width by rotavating soil top layer to 0.03-0.06 m depth; cutting 1.1-1.3 m wide and 0.45-0.65 m deep soil layer at one edge of tilled strip; during lifting of undercut layer and deformation thereof, separating root layer into small-sized and large-sized soil aggregates and root mass; laying extracted and separated roots and rootstocks onto remaining part of tilled strip; simultaneously covering surface of undercut layer having soil aggregates moved to the initial position. Machine has frame, separator with inclined lifters, and rotor positioned behind inclined lifters and equipped with drive having teeth with framed working edges. Machine is further provided with vibrating screen mounted behind rotor, and tray for laying licorice roots and rootstocks at the side of frame. Each lifter is mounted on transverse beam of frame and is equipped with chisel positioned on its lower part. Front face of lifter is made flat, with different angles of inclination with respect to horizontal plane.
EFFECT: increased extent of extraction of licorice roots, reduced power consumption, elimination of erosion and improved conditions for enhanced shoot-forming capacity.
