| 英文摘要 | The aim of this paper was to investigate the effects of the ratio of different nitrogen fertilizers on growth of winter wheat seedling in saline soil in Yellow River Delta.【Method】Costal saline soils at three salinities were studied: 0.9 g/kg (S1), 1.9 g/kg (S2) and 2.9 g/kg (S2). The response of wheat seedlings grown in pots filled with these soils to different combinations of NO_3~--N and NH_4~+-N was investigated. We considered five NO_3~--N∶NH_4~+-N ratios: 100%∶0 (N100A0), 75%∶25% (N75A25), 5%∶50% (N50A50), 25%∶75% (N25A75), and 0∶100% (N0A100) ).【Result】① Nitrogen had a significant impact on the dry mass of the aboveground and underground, the dry mass of the aboveground and underground of winter wheat of N50A50 treatment was the largest. ②Under different salt levels, NO_3~--N∶NH_4~+-N was 75%∶25%, which could promote chlorophyll content of winter wheat, the chlorophyll and soluble sugar content of winter wheat were increased significantly at N75A25 or N50A50 treatment. ③The shoot and root dry weight and total nitrogen content of winter wheat at seedling stages were significantly increased at N50A50 treatment.【Conclusion】The optimal NO_3~--N and NH_4~+-N ratio was 50%∶50% and 75%∶25% in terms of promoting nitrogen uptake by the plant and the accumulation of soluble sugar and chlorophyll, as well as the dry matter of the seedling |
