Optimal Irrigation Regime for Woody Species Potentially Suitable for Effective and Sustainable Afforestation in the Desert Region of Mongolia

Long-term studies on plant response mechanisms to different irrigation regimes will provide a better understanding of the survivability and establishment communities in desert environment. Thus, across 10 years, we regularly investigated effects rainfall (control), + 4 L h−1, 8 12 h−1 growth leaf morpho-physiology Tamarix ramosissima Ledeb., Ulmus pumila L., Elaeagnus moorcroftii Wall. ex Schltdl., Hippophae rhamnoides L. suggest an optimal regime for each woody species effective sustainable afforestation Mongolia. We measured root collar diameter (RCD), annual height growth, survivability, area (LA), specific (SLA), biomass (LB), total chlorophyll concentration, predawn (ψp) midday (ψm) water potentials treatments species. Results showed that trees grown at grew taller per year generally resulted higher SLA, but lower survival rate compared with those other all Total content was under and/or particularly T.
