Summary |
Study
is devoted to definition of cotton water consumption
regularities, reclamation and weather parameters and parameters
of cotton development during vegetation for preparation
of model to predict cotton irrigation schedule in
Hunger Steppe new development zone. Climate-continental;
relief-hilly alluvial plain; soils-loess-like loam,
slightly saline. Ground water table is 1.5-3. 5m. Irrigated
area under cotton is ISOOha, area of plot is lOha. Irrigational
canal is lined by concrete slabs. Plot is equipped with
means of measurement. Multiyear study allowed to calculate
average for decade air temperature and humidity, wind speed,
soil temperature, total evaporation, radiation balance,
turbulent heat exchange and heat influx into the soil as
well as cotton development parameters that allows to
predict moisture distribution in root zone
by mathematical model and operative regime of irrigation
for one-two decades. Results are recommended for practical
application. |
