| 摘要: | Salinization is an important cause of land degradation globally, and these soils are usually nutrient deficient, which inhibits plant establishment and growth.Medicago sativaandLeymus chinensisare important legume and grass forage species, respectively, in China and are frequently used in pasture establishment. We aimed to test whether nitrogen (N) addition can increase the salt tolerance of these two glycophytes and whether the two species inhibit each other at the germination and seedling emergence stages.M.sativaandL.chinensisseeds were germinated separately or together in 0‐, 100‐, and 200‐mM NaCl solutions with supplemental 0‐, 20‐, or 40‐mM N solutions. N addition increased germination percentage and rate, shoot length, and seedling N concentration under moderate NaCl conditions forL.chinensisbut had no effect on Na+concentrations. Conversely, N addition stimulated Na+uptake inM.sativa, but it had little effect on germination parameters, with salt suppressing N uptake. The presence ofM.sativastimulatedL.chinensisgermination percentage in mixed treatments. Our results suggest that proper N application may aid establishment of N‐sensitive speciesL.chinensisin grass–legume mixtures in degraded saline soils, through both direct influence as a nutritional and/or osmotic resource and indirect effect by increasing salt sequestration byM.sativa. N application had little effect on establishment of the N‐fixing speciesM.sativa. |
