Abstract:A pot-grown experiment was conducted to investigate water efficient use mode of Jatropha curcas L. tree, using three irrigation frequency(5 d, 10 d and 15 d)and three SAP usage(ring, half ring and hole), the effects of irrigation frequency and SAP usage on growth and water use efficiency(WUE)of young Jatropha curcas L. tree was studied. Results showed that the WUE sequence of three SAP usage was ring>half ring>hole under same irrigation frequency, and the WUE sequence of three irrigation frequency was 10 d>5 d>15 d under the same SAP usage. When SAP ring application, irrigation frequency of 10 d reduced evapotranspiration obviously, increased soil water content and promoted plant growth significantly, increased total dry mass by 12.89% and 51.83%, and increased total WUE by 51.81% and 58.28% respectively compared irrigation frequency of 5 d and 15 d. Thus the combination of ring SAP usage and irrigation frequency of 10 d could promote young Jatropha curcas L. tree growth and increase WUE under the experiment condition.
