Summary |
Studies
are dedicated to improvement of Syrdarya water resources
use, determination of optimal irrigation norm and rice irrigation
regime on Kazalin massive, soil salinity control through
horizontal drainage and effective irrigation regime. Climate
is continental. Relief is undulated plain. Ground water
table is 1-3 m, salinity degree is from 3 g/1 on irrigated
plots to 10-20 g/1 in sinks without flow. Drain depth is
1.8-2.0 m. Rice fields of Krasnodar type with area within 13.6-19.8 ha. Rice checks area is 1.5-3.5
ha. Specific length of irrigation canals 54-62 m/ha, release
and protective canals 43-48 m/ha. On base of carried out
studies the most favorable for rice water and salt soil
regime is scientifically grounded under optimal combination
of irrigation regime and land drainability degree. |
Key
words |

of rice sowing districts are described, rice agrarian-biological
requirements are characterized. Rice irrigation regime is
given in details both on non-saline and saline lands, measured
values of rice irrigation norms and hydro-modulus are described. |
