Summary |
Investigations
related to complex of reclamation measures development
on warning and second salinity control on a background
of leaching regime and leaching; land drainability increase
by means of close horizontal drainage system construction;
ground of different close horizontal drainage structures
and application of more effective drainage type in conditions
of stratific floating earth, providing maximum reclamation
and technical- economy efficiency. Natural
conditions of experimental plot are typical for the
lower reaches of AmuDarya river. Climate
is continental, dry. Relief is flat. Soils are
saline, sulfate and chloride-sulfate type. Ground
water depth- 0,5-1,0 m, during vegetation period reaches
soil surface, salinity-4,6-15,3 g/l.Experimental
plot area is 214 ha (gross).30 wells
with different filter structures are constructed.Plot is
equipped by measurement and accounting measures.
Investigations
showed that from different filter structures of close
horizontal drainage more effective is small close drainage
from polyethylene pump diameter 125mm with roll winding
and additional sand filling. |
