摘要：
Jujube (Ziziphus jujube Mill. CV. Lizao) is an economically important tree fruit species cultivated in the semi-arid hilly regions of the loess plateau in China. A few studies focused on reporting soil water for this area; so this study aimed to quantify soil water characteristic within 0-1000 cm for dense jujube plantation, using the soil core method and neutron probe. The results showed that: (1) According to soil water dynamic change, the whole soil water profile was stratified into three layers: active layer, difficult recovery layer, and stable layer.(2) The active layer ranged in the 0-200 cm; Soil water of this layer had obvious monthly dynamic change; In May, soil water content was the lowest during the whole growth stage (from May to October); soil water content increased greatly in July and it reached the maximum value in October. The soil water increasing trend was similar to the jujube water consumption trend. This indicated that the stage for jujube vigorous growth was the period that soil water enhanced greatly, but the soil water minimum value appeared in the germinating stage and dormant ending stage. (3) The difficult recovery layer was below 200 cm, and the depth range for this layer depended on the age of jujube plantation. When the age of jujube trees was increased, the depth for difficult recovery layer was also increased. Water consumption depth could reach 540 cm for jujube aged twelve, resulting in a difficult recovery range of 340 cm. Below the difficult recovery layer, there was the stable layer. (4) Therefore, the water consumption depth for dense jujube plantation was less than the depth for Robinia pseudoacacia, caragana microphylla, and alfalfa. The dense planting pattern for jujube plantation has a positive effect on regulating and controlling soil water for artificial forests in the semiarid hilly regions of the loess plateau in the future. ©, 2015, China Water Power Press.
