摘要:
以川西北4种灌丛为研究对象,为明确4种灌丛根系分布特征及对土壤养分的影响,通过野外调查和室内试验相结合的研究方法,分析了川西北4种灌丛(马桑、三颗针、峨眉蔷薇、野花椒)根系分布特征,生物量与土壤养分之间差异性和相互关系。结果表明,4种不同灌丛根系平均生物量的大小顺序依次为:马桑>三颗针>野花椒>峨眉蔷薇,分别为433.3、348.4、416.3、458.3 g,马桑和三颗针明显高于野花椒和峨眉蔷薇。4种灌丛根系生物量的分布特征均是随着土层的加深,根系生物量迅速降低,其中0~20 cm土壤层是4种灌丛根系的集中分布层,4种灌丝根系的生物量占总生物量的比例分别达到59.10%、44.40%、47.61%、44.92%。灌丛根系的主根长基本表现为马桑>三颗针>峨眉蔷薇>野花椒,其中,不同灌丛根长差异显著,灌丛根系的数量、根表面积、根体积的变化趋势与主根长的变化表现出相同的规律,并且根长、根系数量、根表面积的差异显著,4种灌丛根系水平分布差异不显著,不同灌丛的根系垂直分布差异显著。不同灌丛植株碳、氮、钾含量基本表现为马桑>三颗针>峨眉蔷薇>野花椒,不同灌丛植株磷含量差异不显著,除了全磷以外,不同灌丛土壤养分大小依次表现为马桑>三颗针>野花椒>峨眉蔷薇。相关性分析表明,植株碳、氮、磷、钾元素含量与土壤碳、氮、磷、钾元素含量呈显著的相关性,土壤有机碳、全氮含量均与灌丛根系指标有显著的相关性,表明灌丛根系具有保留土壤养分的能力。
