| 摘 要： | 以宁夏3种常见绿化树种金叶女贞、国槐、水蜡一年生容器苗为试验材料,在温室设置不同的盆栽土壤含水量水平,研究这3种绿化树种苗木的生长及生理指标受干旱胁迫影响的动态变化。结果表明:在不同的盆栽土壤干旱胁迫下,水蜡的抗旱性相对较好,其次是国槐,金叶女贞的抗旱性相对较差。 |

| Abstract: | The annual container seedlings of three common afforestation tree species in Ningxia, including Ligustrum vicaryi, Sophora japonica and Ligustrum obtusifolium were used as the experimental materials and different potting soil moistures were set in the greenhouse to study the dynamic changes of the growth and physiological indicators of three kinds of landscape tree species under the drought stress. The results showed that under the soil drought stress of different pot-cultivation conditions, Ligustrum obtusifolium was the best in the drought resistance, Soptlora japonica was the second and Ligustmm vicaryi was relatively poor. |
