摘　　要：了解藤枣原生地的土壤养分情况,为藤枣保护策略的制定提供参考。测量了濒危藤枣原生地土壤的有机质(OM)、全氮(TN)、全磷(TP)、全钾(TK)、水解性氮(AN)、有效磷(AP)、有效钾(AK)和pH,利用云模型方法对藤枣的土壤养分进行了评价。结果表明,藤枣原生地的土壤养分属于较高水平,有机质、全氮、水解性氮和有效钾含量很高,全磷和全钾含量稍低,有效磷含量很低,土壤呈弱酸性。该研究结果提供了参考的土壤养分情况,以期提高藤枣迁地保护和回归种植的成活率。In order to understand the soil nutrient requirements for E.macrocarpa growth,we analyzed soil nutrients and that can provide a reference for a conservation strategy.The organic matter(OM),total nitrogen(TN),total phosphorus(TP),total potassium(TK),available nitrogen(AN),available phosphorus(AP),available potassium(AK)and pH were measured and evaluated.Results showed a relatively high level of nutrients.It was especially high in organic matter,total nitrogen,hydrolytic nitrogen and available potassium,but the amount of total phosphorus and total potassium was slightly lower,and available phosphorus was very low.These results provide a reference for the propagation of E.macrocarpa during ex-situ conservation and reintroduction.
