Summary |
Studies
are dedicated to prevention of unproductive water losses,
reduction of negative phenomena under irrigation on high
permeable soils, increase of wetting uniformity, reduction
of irrigation duration under maintaining positive qualities
traditionally applied irrigation schemes. Plot relief- undulated
surface. According to hydrological aspect - area of limited
ground water inflow and outflow with unstable water table
and regime depending on local conditions. Ground water
salinity 10-20 g/1, salinity type is sulfate-chloride. Soils
- silty sandy loam, gray clayer sands, and more seldom loess
loam with high gypsum content. EPP area is 1 ha. Irrigation
water is supplied from flume canal. Irrigation methods:
cotton crop - on furrows, alfalfa - on stripes with cutting
shallow furrows. In result of studies recommendations on
technological schemes and agricultural crop irrigation technique
on high permeable soils were developed. |
