Summary |
Research
is devoted to soil reclamation regime management through
ground water pumping in combination with leaching irrigation
regime. Relief is hilly; climate-continental. Soils: sandy
loam, light and medium loam, saline , salinity type is sulfate
and chloride-sulfate. Total irrigated area is 174h.ha, vertical
drainage area-15.7th.ha (command area of Kirov canal). Open drainage specific length is 8-15 m/ha. There are 1794
vertical wells with depth of 15-50m. Plot is equipped by
means of water and salt account. In result of research
set of measures on irrigation water productivity
and agricultural lands increase is developed.
Recommended trend of reclamation processes facilitated cotton
yield increase up to 2.8-3.2 t/ha against 1.5-2.0 t/ha initial
yield. Along with land productivity increase specific water
expense per unit production has been reduced (1800-2000cu.m/t
against 4000-5000cu.m/t). |

N.M.Reshetkina, H.I.Yakubov Title: ''Vertical drainage",
Moscow, 1978 Principles of irrigated lands zoning and main requirements
to initial data are developed. System analysis of field
research of soil desalinization and water use improvement
under leaching and leaching regime of irrigation is done.
Main principles of of vertical drainage operation using
ground water for irrigation providing optimal reclamation
regime are found. |
