英文摘要:

In the arid and semi-arid areas, Carex Tussock had deteriorated and disappeared as a result of water deficit and salinization due to human activities and climate changes. A green house experiment was carried out to testify the restoration feasible of Carex Tussock in salinization area. We used a factorial design with two soil conditions (degraded soil occurred salinization and undisturbed soil), two Carex Tussocks (degraded ones resulted from soda-salinization and well ones) and three water levels (long-term drought, seasonal inundation and long-term inundation). In soda-saline soil, degraded Carex Tussock subjected to long-term drought died finally, and could not be revived even the stress was eliminated. Degraded Carex Tussock subjected to the other two water treatments and well Carex Tussock in all water condition went dormant status until environment was improved. However, in the undisturbed soil, except for degraded Carex Tussock under the long-term drought, others successfully survived to the end of experiments, and the degraded ones could be revived when water condition was improved. In undisturbed soil, height, leaf width, leaf area, chlorophyll content and biomass (fresh biomass and dry biomass) of well ones were better than degraded ones. Above results illustrated that it was not feasible to restore Carex Tussock in the soda-saline soils no matter by water condition improvement or well Carex Tussock transplanted. However, transplanting degraded or well Carex Tussock to undisturbed soil could establish successfully. Besides, natural Carex Tussock protection should be paid more attention to avoid soil salinization or secondary salinization. Once salinization or secondary salinization extensively occurred, the degeneration of Carex Tussock would be irreversible.
