METHOD TO CREATE AGROPHYTOCENOSES OF LAND RECLAMATION PURPOSE IN WASTE RICE BAYS Russian patent published in 2011 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and land reclamation. The method includes one-year preparation of soil and combined wide-row sowing of seeds of annual and perennial halophytes, such as common licorice of local ecotype and amaranth. As soil temperature reaches stable +16-18°C, seeds of licorice and amaranth are simultaneously sown in the layer of 0-10 cm in a single row for the depth of 1.5-2.0 cm with the width between rows equal to 0.6-0.7 m with the sowing norms ratio of 1:1. At the second year of licorice plants life, at the stable soil temperature of +16-18°C, girasol and amaranth seeds are sown directly in the layer of 0-10 cm perpendicularly to previously made plantations of licorice and amaranth, for the depth of 1.5-2.0 cm with the width between rows equal to 0.6-0.7 m with the sowing norms ratio of 2:1. Girasol tubers are harvested at the fourth year either in early spring period as planting stock, or in late autumn as fodder or raw materials for pharmaceutical purposes. Root mass of licorice is extracted at the end of the seventh season, and the soil layer is levelled and shaped for the depth of 0.20-0,25 for rice plantations in spring of the following year.

EFFECT: method provides for reduction of mineralised ground water level from 0,5-0,8 m to 1,5-1,8 m, salts carry-over with girasol tubers and licorice root mass up to 286,4 kg/ha and reduction of salts in ground water down to 2-5 g/l.
