Summary: |
The
objective was to develop low-pressure distribution and irrigation
network with simplified design of drippers operating under
water turbidity of 2 g/l and size of sediments of up to
1 mm and allowing uniform water distribution.According to
natural and economic characteristics the pilot plot is typical
for the most part of the SyrDarya river right bank. Relief
is submountain plain. Water table is
more than 20 m. Irrigated area of the plot is 1000 ha. Irrigation network
includes pipelines with ordinary and П-shaped hydrants.
Canals are concrete lined. Area under drip irrigation is
1 ha.As a result it
was established П-shaped hydrants have an advantage over
ordinary ones. This is seen in improved operation, prolonged
life of regulators, and the ability to use this device as
a water meter. Besides, the efficiency of drip irrigation
system, type "Tadjikistan-1", under high permeable
stony soils of Asht massif was determined.
Achieved vine
yield was 15 t/ha under drip irrigation with norm of 6000
m3/ha, while with the check norm of 10000 m3/ha
the yield was 9 t/ha. |
Key

and operation of the distribution pipeline with П-shaped
hydrants (BCH-03-87). 1987Publication details:
Layout of distribution pipelines is given. Design and basic
elements, hydraulic calculation and design, technology of
construction and operation of the system are described.Author(s): N.K.

technology for sloping lands. Dushanbe, "Irfon", 1991.
Publication details:
Environmental conditions are described; existing irrigation
technologies and the cotton and vine irrigation regime are
analyzed. Zigzag furrow irrigation technology and the technology
of using the low-pressure distribution and irrigation system
with vertical bends in places of water supply for furrow
and drip irrigation are justified. Zoning of sloping lands
is made according to irrigation methods and technology,
efficiency of the suggested irrigation technology and technique
is analyzed on the basis of widespread adoption. |
