Summary |
Studies
are dedicated to verification of optimal irrigation norms
of agricultural crops under climatic conditions variation,
analysis of water use state and water use efficiency on
base of water balance studies in experimental-production
tests, elaboration of approaches to effective water use,
establishment of indicators of total and irrigation runoff
from irrigated lands, assessment of irrigation and collector-drainage
water quality as well as giving recommendations on soil
reclamation state improvement in Chu valley. Climate is
continental. Soils - gray desert-meadow and meadow light,
semi-loam. Salinity degree -from slightly saline to strongly
saline, sulfate type. Ground water table is 1.5-3.0 m, salinity
0.6-0.82 g/1. EPP area - 1643 ha (gross) Distributive canals
- in earthen channel, efficiency 0.6. Irrigation water salinity
0.23-0.265 g/1. On EPP closed horizontal drainage network
was constructed, length is 63.22 km, open collector-drainage
network - 9.756 km, specific length 44.4 m/ha. EPP is equipped
by water and salt measurement and account devices as well
as piezometric network. According to carried out field studies
recommendations are developed on water use improvement,
effective water use, given runoff and water disposal from
irrigated lands of water re-use for irrigation. Dependence
of crop yield from water availability is designed. Balance
studies results are given. |

optimal to increase or reduction is accompanied by crop
yield decrease. It is easily to determine value of decrease
by given functions yield-water consumption. |
