Root Water Uptake Patterns for Nitraria during the Growth Period Differing in Time Interval from a Precipitation Event in Arid Regions

Vegetation root water uptake is one of the most central transport processes along soil-vegetation-atmosphere interface particularly in (semi-)arid ecosystems. The identification and quantification activities patterns arid vegetation remain challenging. This paper aims at quantitative examination behaviors Nitraria, a prevalent desert species environments, during growth phase via multivariate linear mixed model based on stable isotopes, with main focus time interval from precipitation pulse. observations indicate that events exert periodic significant pulse-effects through direct absorption (contribution almost 75%) activation deep activity certain depth. While occasions without rainfall, Nitraria relies its extremely extensive shallow roots surface-near lateral zone about 60%) to extract massive soil as well hydraulic lifting mechanism survive drought. Achievements would be beneficial enhancing understanding entangled eco-hydrological feedbacks soil-vegetation ecosystems contribute scientific allocation resources consideration ecological protection.
