FIELD: agriculture, in particular, radical improvement of natural (wild) licorice undergrowth as licorice raw material. ^ SUBSTANCE: method involves mowing and grinding vegetative licorice sprouts and codominant plants in association in low-productive undergrowth by cutting process, with following distribution of ground mass over surface of mown massif; cutting slits on prepared 0.005-0.010 m wide areas to 0.2-0.3 m depth with spacing of 0.8-1.2 m therebetween; simultaneously with slitting procedure, providing two-staged rotavation of upper soil layer, first stage including plowing of upper layer into crumbs at 8-12 cm depth, with following compaction, and second stage including rotavation of surface layer at 3-6 cm depth to agronomically valuable soil fractions, with following compaction. ^ EFFECT: restoration of productive potential of licorice meadows, increased yield of aboveground mass and stock of commercial root as licorice raw material. ^ 2 dwg |
