| 摘 要： | 采用Mehlich3、ASI、Bray、DTPA、HCl等5种浸提方法测定油茶林地土壤磷、铝含量,并分析其与叶片等器官磷、铝含量的关系。结果表明:ASI法提取的磷含量最高,平均值达4.12 mg/kg,Bray法提取的磷含量最低;铝提取量依次为HCl-AlBray-AlM3-AlASI-AlDTPA-Al。5种方法提取的磷、铝含量分别存在较好的正相关关系。油茶叶片的磷含量和铝含量最高,其中铝含量达14.22 g/kg,是其他器官铝含量的11.5~28.1倍。叶片磷含量与HCl-P、叶片铝含量与HCl-Al分别呈显著正相关。该研究表明0.01 mol/L HCl提取法具有应用于同时测定土壤磷、铝含量和评价其对油茶生物有效性的可行性。

| Abstract: | Different extractants of Mehlich3, ASI, Bray, DTPA and HCl were employed to determine the contents of phosphorous and aluminum contents in soils and in different organs of Camellia oleifera, and their correlations were also analyzed. The results showed that ASI obtained the highest soil phosphorus content (4.12 mg/kg), while Bray got the lowest content. The contents of extracted soil aluminum were in an order of HCl-Al>Bray-Al>M3-Al>ASI-Al>DTPA-Al. Soil phosphorus and aluminum contents determined by different extractants had significant positive correlation. Phosphorus and aluminum contents in Camellia oleiferaleaves were highest, aluminum content was up to 14.22 g/kg, 11.5-28.1 times of those in other organs. There were significant positive correlations between Phosphorus content inCamellia oleiferaleaves HCl-P, and aluminum content in leaves and HCl-Al. This study suggests that 0.01 mol/L HCl extraction can be applied to simultaneously measure soil phosphorus and aluminum contents, and to evaluate their bioavailability to Camellia oleifera. |
