【摘要】 本文模拟梯度盐碱化土壤环境,对羊草氮代谢的影响进行研究。结果表明:随着土壤pH值的逐渐升高,羊草总氮量先下降,然后出现了明显的上升,又再次出现了下降的趋势;其中,羊草铵态氮含量大体上表现出了明显的下降趋势;羊草硝态氮含量大体上呈现出先下降后上升再下降的趋势。更多还原

【Abstract】 The paper discussed the responses of Leymus chinensis nitrogen metabolism to simulating soil Salinization.The results showed that the total nitrogen content gradually decreased first and increased after,then there was a downward trend again as the soil PH scale increased.The ammonium nitrogen content in general showed a significant decreasing trend and the nitrate nitrogen content first decreased and then increased again.更多还原
