摘要:
比较了不同淹水发生时间与持续时间对退化盐沼芦苇生长生理以及盐碱土壤理化性质的影响。结果表明，随着淹水持续时间的增加，芦苇株高显著增加，长期淹水条件下芦苇株高最高（FD5），但地上和地下生物量呈先增加后下降趋势，淹水持续2月（FD3）的生物量最高，Na+，K+浓度虽然不规则变化，但最低浓度值出现在FD3处理中。另外，盐碱土壤理化指标（pH值，EC，Na+，Ca2+，HCO3-和CO32-含量）随着淹水持续时间的增加呈先降低后上升趋势，土壤理化性质最优的处理为FD3。随着淹水发生时间的后移，芦苇的株高和地上生物量不变，地下生物量呈先增加后下降趋势，Na+含量呈先下降后上升趋势，芦苇地上器官的K+含量以及盐碱土壤的pH值，EC，Na+，Ca2+，HCO3-和CO32-含量表现为生长初期淹水低于生长后期淹水处理（FO1，FO2优于FO3，FO4）。无论淹水发生时间还是淹水持续时间均对土壤的有机质，K+，Mg2+，Cl-，SO42-含量没有显著影响。因此，6月，7月份是芦苇生态需水期，在此阶段补充充足水分对芦苇的生长恢复具有显著意义，并能改善盐碱土壤的理化性质。
Abstract:
Pot experiments were conducted to compare effects of flooding occurrence time and duration on Phragmites australis growth and soil physical-chemical characteristics in degraded inland marshes. The results showed that both flooding occurrence and duration time affected the growth of P. australis and saline-alkaline soil characteristics. With the increase of flooding duration, height of P. australis increased with the highest value in FD5. The above and under ground biomass increased first and then decreased with the highest value in FD3 (2 months flooding). Although Na+ and K+ contents did not show a regular change, they was the lowest in FD3. The characteristic parameters (pH value, EC, Na+, Ca2+, HCO3- and CO2-3content) decreased first and then increased with the lowest value in FD3 too. With delay of flooding occurrence time, there was no change on height and aboveground biomass of P. australis, but the tendency of underground biomass increased first and then decreased. Na+ had opposite tendency of underground biomass. The K+ content and the main characteristics of soil showed lower value in FO1 and FO2 treatments than FO3 and FO4 treatments. Meanwhile, flooding occurrence and duration time had no significant effects on organic matter, K+, Mg2+, Cl-, SO42- contents. Therefore, June and July was the key growth period with enough water. Supply water at this stage was quite important for restoring P. australis growth, and also improved the quality of saline-alkaline soil.
