英文摘要 | Soil salinization and nitrogen (N) enrichment in saline-alkali soils resulting from human activities cause potential environmental pressure on Phragmites australis. However, the response of P. australis to N addition under different salt conditions remains unknown. This study examined the changes in soil properties and growth indices as well as their relationship to N addition through an in situ field experiment using three soil salinity levels with P. australis in the Yellow River Delta. The study showed that soil salinity levels significantly affected the effects of N addition on soil pH and water contents. N addition increased the soil NO3- contents and decreased soil available phosphorus (Avail. P) contents; however, soil salinity levels did not impact the effects of N addition on soil NO3- and Avail. P contents. N addition decreased the biomass of P. australis, since the decrease in the competitiveness for N sources changed the vegetation diversity. The results suggest that the biomass, plant height, and leaf soil plant analysis development (SPAD) values of P. australis increased with increasing soil Avail. P contents rather than soil NO3- contents. Therefore, we suggest the important role of Avail. P addition in N enrichment conditions in saline-alkali wasteland and estuarine wetland ecosystems. |
