摘要
通过文献查阅、走访调查及实地调查的方式,对西双版纳勐养子保护区内47条样线进行藤枣分布调查,并对藤枣生长的土壤理化性质以及藤枣的保育方式开展研究。结果表明:47条样线中共有7个地点发现7个种群122株藤枣,7个样点土壤有机质含量均较高,pH值均为弱酸性,pH范围在4.89~6.44之间,其中5个样点土壤有机质含量均在20 g/kg以上,藤枣喜在土壤有机质含量较高且呈弱酸性土壤环境中生长。大荒坝南木河土壤中氮磷钾总量最高,为26.17 g/kg,昆罕小寨最低,为7.0420 g/kg,土壤中氮磷钾总量对藤枣分布数量并无直接关系。新鲜水苔做为基质的扦插繁育中获得5株成活株,成活率为12%。
This study conducted a distribution survey of Eleutharrhena macrocarpa along 47 sample transects within the Mengyang Conservation Area in Xishuangbanna through literature review,field investigations,and on-site surveys.The study also examined the physicochemical properties of the soil where the species grew and the conservation and breeding methods for Eleutharrhena macrocarpa.The results revealed that a total of 122 Eleutharrhena macrocarpa individuals from seven populations were found at seven sampling sites.The soil at these sites had relatively high organic matter content,with pH values falling within the weakly acidic range(4.89-6.44).Five of the seven sites had organic matter content exceeding 20 g/kg.Eleutharrhena macrocarpa was prefer to grow in soils with high organic matter content and weakly acidic conditions.Among the sites,the highest total nitrogen,phosphorus,and potassium content was recorded at Dahuangbananmuhe(26.17 g/kg),while the lowest was found at Kunhanxiaozhai(7.0420 g/kg).However,no direct relationship was observed between the total nitrogen,phosphorus,and potassium content in the soil and the distribution density of Eleutharrhena macrocarpa.In the cutting propagation using fresh sphagnum moss as the substrate,5 viable plants were obtained,with a survival rate of 12%.
