The salinization problems and soil hydromorphism as components of land desertification, irrigated zone of Tajikistan and the liquidation ways of them

摘要

In this article, speak about the reveal the main causes and ways to eliminate the problems of salinization and hydromorphism of soils in the Republic of Tajikistan, since salinization is one of the main stressors, that limit the growth and productivity of agricultural plants. The existing studies show, that there are two ways of integration: passive and active. Passive, through the selection of salt-resistant and moisture-loving tree crops and their transpiration capacity. Active also offers a special reclamation survey of the sides of drains and reservoirs and the use of reclamation measures aimed at achieving good survival and survival of young seedlings. Bio-drainage consisting of local tree species under a certain arrangement can transpire a volume of water commensurate with and even superior to pumping them out by vertical drainage wells. This indicates, that it is possible to remove local ground water pressure and change the existing structure of the ground flow in the agricultural landscape.
