[Objective] The research aimed to investigate the sisal soil in Wanning, Hainan. [Method] Soil samples of pineapples were collected from Wanning, and analyzed with normal methods. [Result] pH of pineapples soil was acidity, the average was 5.43. The percentage of level 5 was 40. 00% . The organic matter content was in a low level, and the average was 19. 21 g/kg. The nitrogen content was in a low level, and the average was 0. 89 g/kg. The available phosphorus content was different in different area, and the average was 52. 50 mg/kg. The available potassium content was low by large, and the average was 48. 33 mg/kg. [Conclusion] Based on the analysis of nutrient content in pineapple soil, the difference of pH was little, those of organic matter and the others were bigger, and that of available phosphorus content was the most significant.%[目的]采集海南省万宁市菠萝产区土壤,分析、比较土壤养分.[方法]采用常规分析的方法,测定土壤养分.[结果] pH以酸性为主,平均值为5.43,属于5级微酸性土的采样点占总数的40.00％；有机质含量处于较缺水平,平均值为19.21 g/kg；全氮含量为缺乏水平,平均值为0.89 g/kg；不同地区有效磷含量间差异较大,平均值为52.50 mg/kg；有效钾含量总体上偏低,平均值为48.33 mg/kg.[结论]海南不同地区菠萝土壤养分含量对比,pH差异较小,有机质及其他养分含量不同地块间差异大,差异最大的有效磷含量.
