Summary |
Studies
are dedicated to development of measures set on reducing
water consumption and water disposal norms by using effectively
surface and ground water for irrigation, optimizing vertical
drainage operation regime, increasing ground water share
in sub-irrigation, reducing water discharge for physical
evaporation. Climate is continental. Relief is slightly
undulated. Soils - heavy and semi-loam, 65-70% of area -
non-saline, 20-25% - spot salinity, 5-10% - medium and weakly
saline, chloride-sulfate type. Ground water is saline (1-3
g/1), hydro-carbonate-calcium and hydro-carbonate-sulfate
type, more seldom calcium-magnum-sodium. EPP area is 8.5
ha, land use efficiency 0.7. Water supply - from distribution
canals. One third of irrigation network has anti-filtration
cover, efficiency 0.75. Vertical drainage wells- 60. Main
result of studies - reclamation situation improvement, sustainable
high yields of basic for this zone crops (cotton, cereals,
alfalfa for hay), under water diversion reduction, water
consumption annual norm reduction at the expense of synchronizing
vertical drainage operation regime with water supply and
irrigation regime. |

KazNIIGiM coll. of research papers, 1997 Changes of soil
physical-chemical properties, salt continent, absorbed
basis, drainage water salinity are given. It is established
that norms of water disposal and consumption providing favorable
reclamation situation on irrigated lands depend on ground
water regime, soil and irrigation water salinity degree. |
