Studies are dedicated to following issues:
- establishing
optimal regimes of high frequency watering under agricultural
crops drip irrigation on fine-grained deposit of low thickness;- comparison
of agricultural crops water consumption coefficients on
the background of surface and drip irrigation;- establishing
drip irrigation technical-economic indicators on base of
existing ground water wells use;- agrarian-economic
assessment of drip irrigation comparing to furrow irrigation;
Climate is continental. EPP area - 5 ha. Irrigation
network - domestic drip irrigation system (plastic hoses
with droppers "Vario-drip", set in intervals 0.9
m)Irrigation source - water well with capacity 45 l/sec.
Control site - furrow irrigation.Operation for 4 years (1993-1996) of EPP existing well
"for irrigation" to supply with ground water DIS
proved its true reliability, because range of DIS functioning
issues was solved:
1. Irrigation
water production;2. Irrigation
water transport to irrigated field;3. Irrigation
water clarification;4. Creation
of necessary water head for DIS capacity.
In Fergana valley about 35-40 th. ha adyr lands can
be irrigated due to available SPO and CDS. |
