Summary |
Analysis
of irrigation network efficiency, irrigation technology,
and uniformity of irrigation water and wetting distribution
over irrigated plots area in different zones under existing
irrigation methods was carried out. Assessment of agricultural
crops' irrigation efficiency was carried out with new
irrigation methods application. Comparative analysis
results showed that of all existing irrigation methods
the most effective is drip irrigation. Under drip irrigation
on EPP 5.5-6.0 t/ha raw-cotton, on sloping plots 18-20
t/ha grape and apple were obtained. Water saving is
1.5-2 in comparison with furrow irrigation. Soil washing
off and erosion are excluded totally, especially mudflows
in mountainous conditions, fertilizers application norm
is reduced by 20-25% at the expense of lack of release
and percolation, uniform wetting over area occurs. Plants
care is facilitated. It is possible to achieve total
mechanization and automation of water allocation, etc. |
