Summary |
Studies
are dedicated to irrigation water unproductive losses' reduction,
irrigation process automation, and ecological situation
improvement. Relief is smooth. Soils - gray desert-meadow,
non-saline, with amall spots of slight salinity, light and
semi-loam with inter-layers of heavy loam and gypsum and
carbonates' content Ground water is slightly saline with
water table 2.7-3.0 m (autumn-winter). EPP area- 120 ha
(net). Irrigation network - in-soil irrigation system, connected
with flume network, equipped with gate-regulation devices.
Control - furrow irrigation. During process of studies network
parameters, irrigation technique elements, in-soil irrigation
regimes, providing land use efficiency increase, irrigation
efficiency increase, sustainable high crop yields obtaining
were amplified. In-soil irrigation technique and technology
were developed. |

Author -StulinaG.V. Title - "Soil water regime under
in-soil cotton crop irrigation in conditions of Hunger steppe"
Material of the republican agriculture seminar Tashkent,
1979. Results of studies of cotton crop in-soil irrigation
technique and technology and soil water regime under various
irrigation regimes are given. Optimal in-soil irrigation
regime providing uniform wetting and irrigation efficiency
increase. For conditions of Hunger steppe range of suction
pressures relevant to optimal soil humidity was studied.
Irrigation norms and depths were given. Specific water
expenses, water saving under in-soil irrigation, and raw-cotton
yields were shown. |
