| Abstract: |
| ln order to research the effects of fertilization on Na+ accumulation and growth of Salicornia europaea L., field experiments were conducted to study the effeets of nitrogen levels on the growth, accumulative amounts of Na+ Salicornia europaea L.The results indicated that the yields of grain, stem, and assimilation shoot increased with N fertil-izer application. The relationship between grain biomass, assimilation shoot yield, and the N application rate was in rec-tilinear correlation. With increasing nitrogen application, the concentration trend of Na+ was not significantly changed. The concentration of Na+ in assimilation shoot was significantly higher than that in grain and stem. The accumulative amounts of Na+ in Salicornia europaea L increased with N fertilizer application. Among different nitrogen treatments, the highest Na+ accumulative by Salicornia europaea L.was N600(9668 kg/hm2), which was 4.7 times of CK(2045 kg/hm2). Under the conditions of this experiment, fertilization could stimulate Salicornia europaea L. growth and strengthen the effectiveness of bio-remediation of saline soil. |
