Effect of soil moisture on evapotranspiration of a maize stand during one growing season

Original language description

The cumulative evapotranspiration of maize stand was determined during the growing season over the period of 148 days from planting to the full ripeness. The total evapotranspiration in this time interval was 276,4 mm while the amount of precipitation reached in the analysed period 295,4 mm. The transpiration and soil evaporation daily courses were calculated using a verified mathematical model of interrelationship existing within the system soil-plant-atmosphere. In the vegetation period 2000 the investigated maize stand transpirated under changing environmental conditions. It was found that soil water availability practically did not affect the evapotranspiration when at least 58,2% of extractable soil water was present in the root zone, but below this value, the evapotranspiration decreased linearly with the decrease in the soil water content.

Vliv půdní vlhkosti na evapotranspiraci porostu kukuřice během vegetační doby

Czech description

Ve vegetačním období 2000 studovaný porost kukuřice transpiroval v různých podmínkách prostředí a za významného poklesu půdní vlhkosti zaznamenané na konci června. Zjištěno bylo, že dostupnost půdní vody prakticky neovlivnila evapotranspiraci, pokud alespoň 58,2% extrahovatelné půdní vody bylo přítomno v kořenové zóně, ale pod touto hodnotou klesala evapotranspirace lineárně s poklesem obsahu půdní vody.
