Abstract：In order to provide theoretical support to improving growth and water use efficiency of Jatropha curcas L. with different irrigation under salt stress treatments, three salt(pure NaCl)contents(S0:0 g/kg, S1:2.5 g/kg, S2:5 g/kg)and three water levels(W1:0.9 L, W2:1.8 L, W3:2.4 L)were used in a pot experiment for 63 days. The study showed that height diameter, stem diameter, healthy index seedlings, dry matter and irrigation water use efficiency at W3 were significantly higher than those at W1 and W2 in the same salt condition. So the best water level was W3. Compared with W3S0, W3S1′s dry matter, water use efficiency were increasing greatly and there was no distinct difference between W3S0 and W3S2. Thus, in low salt stress condition, the suitable amount of water irrigation control was good for plants′ growth and water use efficiency. In high salt stress condition, the suitable amount of water irrigation control was helpful for Jatropha curcas L. to improve the ability to adapt to the salty environments.
