Abstract: To understand the soil nutrient and water status of main producing area of Ziziphus jujuba cv.Lingwuchangzao in Ningxia, six representative planting bases were selected to analyze the content of pH, total salt, organic matter, alkali-hydrolyzed N, available P, available K and water. Results showed that the average pH, total salt,organic matter, alkali-hydrolyzed N, available P, available K of jujube orchards soil were 8.36,1.46 g/kg, 6.68 g/kg, 47.83 mg/kg, 21.07 mg/kg and 127.61 mg/kg respectively. Compared with the 2nd National Soil Survey, the organic matter and alkali-hydrolyzed N content were lack, the available P was very abundant, the available K was abundant. The nutrient status of Orchard Village and Daquan forest farm were better. In terms of soil water content, the Orchard Village was higher, the Lyuyuanheng and Zhongxi Company were lower. The development of soil nutrient and water content in different bases were unbalanced.

Key words: Ziziphus jujuba cv. Lingwuchangzao, soil, nutrient, water, Ningxia
