Abstract:
Four-year-old Lingwu long jujube （Zizyphus jujuba Mill.cv.) was used as material,using two variables nested design,with two different settings for temperature,normal air temperature,elevated 2.0 ℃ more than normal temperature,using infrared radiation equipment to control simulating elevated temperature environment,and automatic irrigation system to control soil water levels（70%-80%，50%-60%，30%-40%）.The effect of elevated temperature and drought stress to growth and photosynthesis on Lingwu long jujube was studied in order to provide references for cultivation management of Lingwu Long jujube.The results showed that elevated temperature could improve the growth and photosynthesis of Lingwu long jujube,particularly shoots length,leaves area,Pn,E,IWUE.But Gs,Ci were reduced,elevated temperature could relieve the adverse effects of drought stress on the growth of Lingwu long jujube.
