Summary |
Studies
are dedicated to establishment of agricultural crops
water consumption norms for different natural-economical
conditions of Tadjikistan in relation with change of
technical level of hydro-reclamation systems and year
water availability. Statistical processing of meteorological
data of all meteostations of Tadjikistan was carried
out, values of temperature and relative air humidity
and precipitation were defined under 5, 25, 50, 75,
95 % availability, evaporability deficit (evaporability
minus precipitation for period IV-IX) was calculated
for these values of meteorological parameters availability.
Values of wetting coefficient were defined, isolines
of wetness were drawn on map. Agroclimatic zoning of
cotton sowing zone of Tadjikistan was carried out. Methodic
of calculating gross irrigation norms was developed,
coefficients included in formula of irrigation norms
calculation were amplified. |
