Summary |
Investigations directed at effective organization
of irrigations and agricultural works for cotton cultivation
on basis of irrigations technique optimal elements setting
up, concentrated irrigations realization, irrigation regime
and feeding planning according to yield planned, in-farm
water use planning and management improvement, increase
of fertilizers and other resources use efficiency for cotton
cultivation. Plot is located in Gissar valley. Climate is sharply
continental.Soils are made of old irrigated light sierozems
and brown carbonate, non-saline, heavy, medium and light,
slightly stony. Ground waters are at big depth, fresh and
slightly mineralized. Plot irrigation is implemented from
Great Gissar canal with mineralization less than 0.7 g/l.
Plot area is 76 ha (net).Irrigation network is open, efficiency is
0.85-0.90, specific extent is 64 m/ha. As a result of investigations the algorithms
are developed for coordination of irrigations, the pivot
of which is irrigation schedule of each plot.
For the purpose of initial data collection,
processing and storage automation special automatic system
"Meliorator" which provided on 18000 ha cotton
yield increase 0.2 - 0.4 t/ha, plant growth improvement,
1600 m3/ha irrigation water saving. |
Key words |
