To improve ecological efficiency of Chinese jujube orchard and to further dig out its productive potentiality, comparative tests between intercropping wheat with Chinese jujube and single-cropping wheat were conducted. The results showed that intercropping wheat with Chinese jujube could obviously decrease dry-hot winds in wheat field; Bulk density and temperature of the soil were decreased, and the total porosity, capillary porosity, capillary moisture capacity and moisture capacity were apparently improved ( P
