Summary |
Study
is directed to ground water table rise prevention, settlements
inundation, soil productivity increasebased on drainage
strengthening, leaching and leaching regime of irrigation,
development of set of measures on ecological-reclamation
situation improvement and soil water-salt regime management.
Plot is located near Kumsangir canal. Climate is continental,
dry. Relief-weakly sloped plain. Soils-sierozems, partially
saline, (3g/l on average), sulfate type. Ground water depth
is 0.4-3 .Om. Irrigated area is 40ha (net). Irrigation network-flumes,
specific extent 76.2m/ha, efficiency is 0.84. Subsurface
drainage specific extent is 67.2m/ha, depth 1.6-3.5 m. In
result of research main drainage parameters are optimized,
new parameters are given, water saving technology is applied,
plans of irrigation regime are developed for irrigation
system efficiency improvement. inciples of land desalination
have been developed by means of outstripping subsurface
drainage construction taking into account precipitation,
reducing term of land development. Subsurface drainage
main parameters and design are recommended. |

Results of scientific research are given on cotton yield
programming under irrigation water saving. Operational plans
of irrigation regime are developed, measures on irrigation
network efficiency increase, ground water table impact on
cotton development definition. |
