| 摘 要： | 采用网格布点法收集海南岛较大的洋田水稻土样52份，分析测定土样的pH值、全磷、全氮、全钾和有机质5个养分指标，并对其进行分析与评价。结果表明：海南水稻土为酸性土壤，其pH值平均为5.94；海南水稻土养分水平以中低级为主，占总数的74.9%，普遍表现为土壤有机质和钾的含量低；不同母质形成的水稻土之间土壤养分差异不显著。

| Abstract: | The paddy soil of 52 larger farmlands was collected with the method of grid distribution in Hainan Island. The soil nutrient index was measured and analyzed, which is pH, total P, total N, total K and organic matter. The result of analysis and evaluation showed that the average pH of paddy soils was 5.94 in Hainan, which was the acidic soil. The nutrition of paddy soil in Hainan was the main middle-low level that was accounted for 74.9 %. The content of organic matter and K in soil were generally low level. Soil nutrition between paddy soil derived from different parent materials did not exist a significant difference. |
