FIELD: agriculture. ^ SUBSTANCE: invention refers to agriculture, in particular, to land reclamation. Method includes main treatment of soil for depth of 27-30 cm, surface treatment of soil, levelling of relief, preparation of planting stock in the form of hefts from licorice roots with length of 20-25 cm of four-five years of age with 4-6 auxiliary renewal buds, formation of holes with depth of up to 0.3 m, planting and care. Hole is shaped as a truncated cone, wide base of which matches surface of the rice bay soil. Hole is arranged with depth of 25-30 cm with small base diametre of 0.5-0.6 m and large base diametre of 1.2-1.5 m. Holes are arranged in staggered order on surface of rice bay with distance from each other of 2.4-3.2 m. In bottom part of hole in radial directions 6-10 hefts of licorice roots are laid, hole is filled with substrate, at the depth of 12-14 cm from upper base of hole, above hefts of licorice roots, coated with substrate, 12-24 girasol tubers are laid. Large base of hole is coated with 12-24 arc sectors from soddy layer saturated with roots and rhizomes of solonchak wheat grass with sod cover thickness of 6-8 cm, surface of sod layer with rhizomes of solonchak wheat grass is coated with a layer of substrate with thickness of 2-6 cm. ^ EFFECT: method provides for reduced level of ground waters, extent of their mineralisation and carry-over of salts with vegetative mass of common licorice, solonchak wheat-grass and girasol beyond the borders of rice bay. ^ 2 dwg, 1 tbl |
