摘要/Abstract

摘要： 环境中氮水平的升高增强了入侵植物互花米草（Spartina alterniflora）的适应能力和入侵能力。然而，采取碳添加措施减少土壤氮含量控制互花米草的相关研究却鲜有报道。本研究在模拟潮汐环境中，设置两个碳源种类（葡萄糖、乙酸钠）、两个碳添加量（400、800 g C·m^-2），外加一个对照处理（CK），分析不同碳添加处理对互花米草生物量和根、叶形态性状相关指标的影响。结果表明，碳添加显著降低了土壤硝态氮和互花米草的根、茎、叶生物量（P<0.05）。碳添加量为800 g C·m^-2时，显著减少了互花米草侧生根长、不定根长、根表面积、比根长、叶长、叶宽、叶周长、叶面积、比叶面积，显著增加了互花米草侧生根长/不定根长、根组织密度（P<0.05）；但不同碳添加处理对互花米草茎叶比和叶片长宽比无显著影响（P>0.05）。相关性分析表明，互花米草生物量与碳添加量呈显著负相关，互花米草根组织密度和侧生根长/不定根长与碳添加量呈显著正相关（P<0.05）。总体而言，碳添加减少了土壤中的硝态氮含量，并显著抑制了互花米草的生物量以及根、叶的生长。本研究结果有助于预测入侵植物对环境养分管理措施的响应，为互花米草的治理提供新思路。

Abstract: Elevated nitrogen levels in the environment enhance the adaptability and invasive ability of Spartina alterniflora. However, there is limited research on reducing soil nitrogen content by carbon addition to control Spartina alterniflora. In this study, under simulated tidal conditions, we used carbon addition to reduce available soil nitrogen. We set up an experiment with two types of carbon sources (glucose and sodium acetate), two carbon addition levels (400 and 800 g C·m^-2), and a control (CK) to analyze the effects of carbon addition on S. alterniflora biomass and root and leaf morphological traits. The results showed that carbon addition significantly decreased soil nitrate nitrogen and the biomass of roots, stems, and leaves of S. alterniflora (P<0.05). When the rate of carbon addition reached 800 g C·m^-2, it significantly reduced lateral root length, adventitious root length, root surface area, specific root length, leaf length, leaf width, leaf perimeter, leaf area, and specific leaf area, and significantly increased the ratio of lateral root length to adventitious root length and root tissue density (P<0.05). However, carbon addition treatments had no significant effect on stem-to-leaf ratio and leaf length-width ratio of S. alterniflora (P>0.05). S. alterniflora biomass was significantly negatively correlated with carbon addition level, while root tissue density and the ratio of lateral root length to adventitious root length were significantly positively correlated with carbon addition level (P<0.05). Overall, carbon addition reduced soil nitrate nitrogen content and significantly inhibited the biomass of S. alterniflora as well as the biomass of roots and leaves. Our findings could contribute to predicting the response of invasive plants to nutrient management measures and provide new insights for the management of invasive S. alterniflora.
