METHOD OF FORMING WHEATGRASS-LICORICE AGROPHYTOCENOSE ON SALT-AFFECTED SOILS WITH CLOSE GROUNDWATER OCCURRENCE Russian patent published in 2013 - IPC A01B79/02 A01G25/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular, to soil reclamation. The method includes conducting of primary and pre-sowing soil treatment, planting in furrows of cuttings from licorice rootstocks, narrow-row sowing of wheatgrass and harvesting wheatgrass-licorice hay and licorice rootstocks. Formation of agrophytocenosis is carried out in I-II decade of October by alternating the bands of common licorice - 3 rows and wheat grass - 5 rows. And the distance between the furrows of licorice is 0.3 m, and between the rows of wheatgrass is 0.15 m. In the first year of formation of the plantation the two-fold mowing for hay of wheatgrass tops is carried out to a height of 0.12-0.15 m. On the 2-5^th year, up to 2-3 mowing of wheatgrass-licorice hay is carried out. And during five years after each mowing of tops of wheatgrass-licorice agrophytocenosis the mineral feeding is carried out, irrigation with water with the salinity of less than 1.8-3.0 g/l while maintaining the threshold of preirrigation soil moisture not lower than 65-70% minimum water capacity. The rootstocks of licorice are harvested at the end of the growing season of the 5^th year of life of wheatgrass-licorice agrophytocenosis.

EFFECT: method enables to improve the phytomeliorative effect contributing to reduction of content of water-soluble salts in the arable soil layer, to reduce the level of ground water, and increase the yield of high-protein cereal-legume hay and medicinal licorice raw material.
