| 中文摘要: |
| 为探明华南地区菠萝主产区的土壤养分状况，测定了广东湛江、广西南宁和海南万宁11个菠萝产区96个土壤样品的养分含量，并进行比较分析。结果表明，广东、广西和海南土壤均为酸性，pH值分别为4.36、4.66、5.43；土壤有机质广东较丰富，而广西、海南较缺乏，分别为为3.27%、1.77%、1.93%；全氮含量广东处于中等水平，广西、海南较缺，分别为0.13%、0.08%、0.09%；速效磷含量丰富，分别为33.06、38.41、52.50 mg/kg；而速效钾含量缺乏，分别为87.50、59.29、48.33 mg/kg；交换性钙含量极丰富，分别为2 879.12、6 683.33、8 094.93 mg/kg；交换性镁含量分别为205.94、333.60、328.00 mg/kg，均处于丰富水平；有效铜含量广东最高，为2.43 mg/kg，处于丰富水平；有效锌含量海南最低，为0.51 mg/kg，处于中等水平；有效锰含量广东最大，为12.00 mg/kg，处于中等水平。广东、广西和海南土壤有效铁含量极丰富，分别为87.50、59.29、48.33 mg/kg。 |

| In order to understand the overall situation of soil nutrient of pineapples in Zhanjiang city Guangdong province, Nanning city Guangxi Autonomous Region and Danzhou city Hainan province, the investigation and analysis on soil nutrient of pineapples orchards were conducted.The results showed that pHof pineapples soil in Guangdong, Guangxi and Hainan were acid. The organic matter content was in a high level in Guangdong and in a low level in Guangxi and Hainan province. The average of the organic matter content of Guangdong,Guangxi and Hainan were 3.27%，1.77%, 1.93%. The Ncontent was in a medium level in Guangdong and in a low level in Guangxi and Hainan province. The average of nitrogen content of Guangdong,Guangxi and Hainan were 0.13%, 0.08%, 0.09%. The available P content was rich in all provinces, and the average of available P were 33.06, 38.4, 52.50 mg/kg. The availableK content of all provinces were in a low level, and the average were 87.50,59.29, 48.33 mg/kg. Exchangeable Ca , Mg was in a higher level. The available Cu content of Guangdong was highest, and the average was 2.43mg/kg. The available Zn content of Hainan was lowest, the average was 0.51 mg/kg. The available Mn content of Guangdong, Guangxi and Hainan was 12.00, 1.11, 3.81 mg/kg. The available Fe content of all provinces was at a higher level, and the average were 87.50, 59.29, 48.33 mg/kg. |
