| Abstract: |
| In order to study soil water condition of pear jujube trees in the loess plateau, the soil water in 0~160 cm and 0~700 cm ranges in depth for different cultivation years(1 a, 4 a, 9 a, 12 a) of pear jujube trees was moni-tored by TRIME tubes and Luoyang Spade under irrigated and rain-fed conditions. The results showed that: soil water re-tention(SWR)of pear jujube trees declined as the growth of age; Compared with that of rain-fed pear jujube trees, the SWR of primary root zone (0~160 cm) was higher under the condion of irrigation; With the existing irrigation quota, the average satisfying degree of root zone of pear jujube trees to soil water was relatively low under the condition of irriga-tion; The distribution depth of dried soil layer and soil desiccation intensity tended to inerease for rain-fed pear jujube trees with the increase of age. |
