摘要:
采集乔木(细叶榕、桂花和香樟)、灌木(金叶女贞、小叶黄杨和红叶石楠)和草本(彩叶草、波斯菊和紫茉莉)3大类9种园林植物的根际和非根际土,测定其土壤的pH值、有机质含量、氮含量、磷含量、钾含量,以探讨不同园林植物根际和非根际土壤的养分状况。结果表明:由于不同种植物通过根系调节pH值的能力不同,植物根际和非根际土壤pH值差异显著(P<0.05);植物根际和非根际土壤有机质和总氮含量差异显著(P<0.05),桂花和波斯菊根际和非根际土壤速效氮含量差异不显著(P>0.05),其他作物速效氮含量差异显著(P<0.05);金叶女贞、波斯菊和紫茉莉根际和非根际土壤总磷含量,桂花和波斯菊根际和非根际土壤速效磷含量差异不显著(P>0.05),其他植物差异显著(P<0.05);不同园林植物根际和非根际土壤全钾含量差异不明显,桂花、香樟、金叶女贞、小叶黄杨、红叶石楠及波斯菊根际和非根际土壤速效钾含量差异显著(P<0.05);越秀公园园林植物根际和非根际土壤有机质、氮、磷缺乏或中度丰富,而钾很丰富。相关性分析结果表明,土壤pH值和氮、磷、钾与园林植物生长发育存在显著相关性,土壤pH值与氮、钾含量存在负相关性,有机质含量与土壤氮、磷含量存在极显著相关性(P<0.01)。
