Ecological restoration of degraded pasture lands in the Circum-Caspian Sea semi-desert

Abstract

For the ecological restoration of desert lands, the dominant species of fodder plants of the natural flora of the violent and patient ecology were used: Krascheninnikovia ceratoides (L.) Gueldenst., Bassia prostrata (L.) A.J. Scott, Camphorosma lessingii Litv., Artemisia lerhiana L., A. pauciflora Web., Poa bulbosa L. in various quantitative ratios in mixtures. Polydominant pasture ecosystems occupy different tiers of height in the aboveground sphere: semi-shrubs - up to 120-140 cm, dwarf semi-shrubs - up to 45-75 cm, ephemeroid grasses - up to 15-25 cm. This ensures efficient placement of the leaf apparatus for efficient photosynthesis. In the underground sphere, various life forms of fodder plants form root systems and develop various ecological niches for more efficient use of water and mineral resources of a large volume of soil. Polydominant pasture ecosystems, which include various plant life forms, provide higher feed production, which exceeds the production of natural pastures by 3-5 times.
