Using collector-drainage water in saline and arid irrigation areas for adaptation to climate change

Abstract

The paper presents data of scientific research on the conditions of the Bukhara oasis of Uzbekistan reducing the salinity of collector-drainage water through water plants Lemna minor, Azolla caroliniana, Eichhornia crassipes and scientific and practical recommendations for the irrigation of cotton biologically purified collector-drainage waters. A decrease in the salinity of collector-drainage water with a salinity of 3-5 g/l was achieved with the help of aquatic plants Lemna minor and Azolla caroliniana, using them as an additional source of water for irrigation of cotton variety Bukhara-102, a high harvest of raw cotton, as well as saved river water and prevented environmental pollution.
