METHOD FOR CREATION OF LONG-TERM PLANTATIONS OF LICORICE CULTURE GLYCYRRHIZA GLABRA L AND GLYCYRRHIZA URALENSIS FISCH ON PREVIOUSLY IRRIGATED LANDS

摘要

FIELD: agriculture.;SUBSTANCE: in this method ground is tilled, plant shanks from rhizomes of licorice with planting rate of 2-3 pieces on 1 running m at the age of 3-5 years, length of 0.20-0.25 m on depth of 0.15-0.25 m with distance between rows of 0.6-0.7 m in narrow strips in width of 1.2-1.4 m, and perform planting of vegetable cultures sprouts in wide strips to the same agroterms between narrow strips. Perform post planting compaction of plantation surface under the pressure of 0.15-0.20 MPa. Form site with drop irrigation on irrigated land, flexible distributive pipelines with stop valves and irrigation pipelines with built - in droppers are laid perpendicularly to an axis of the flexible distributive pipeline with interval of 4.8-5.6 m. Flexible irrigation pipelines with droppers built in them are laid annually. Irrigation of rows of vegetable cultures and licorice carry out with norm of irrigation water discharge for maintenance of a threshold of humidity of 70-80-70% HB in root horizon during the May-August period, also mineral supply conditions are kept up. Annually in wide strips after crop harvesting perform soil treatment with soil overturning or rotary tillage on depth of 0.12-0.18 m. Cleaning of distributive and flexible irrigation pipelines are performed after harvesting of vegetables. On the 5th year of licorice plants life on plantation, perpendicularly to the plantings, executed in narrow strips in width of 1.2-1.4 m, licorice shanks are planted, width of row-spacing makes 1.4-2.8 m. On 6-10 years of licorice plants life its plantations are used as fodder and haying grounds, and about 11-14 years after, industrial extraction of licorice roots is carried out from a layer of 0.4-0.6 m as liquorice raw materials.;EFFECT: method allows to create steady licorice communities on previously irrigated lands.;2 dwg
