| 摘 要： | 对海南万宁、琼海、定安和屯昌4个主要槟榔间作香草兰种植区0～20 cm土层的60个土壤样品进行分析。结果表明，pH值呈酸化的趋势，低于临界值；有机质含量适中，呈上升的趋势；碱解N含量适中，呈下降的趋势；速效P和速效K含量呈下降的趋势，且低于临界值；交换性Ca含量呈上升趋势，但低于临界值；交换性Mg含量低于临界值，呈下降趋势；有效B含量高于临界值，呈上升趋势；有效Fe、有效Mn、有效Cu和有效Zn含量均高于临界值，呈下降趋势，其中有效Mn含量超标。

| Abstract: | The results of soil fertility of 60 soil sample from Wanning, Qionghai, Dingan and Tunchang counties in Hainan were that the value of pH was acidified to below the critical value. The organic matter content is moderate rising trend, alkaline hydrolysis the N content in moderate downward trend. The downward trend of available P and available K are lower than the critical value. Exchangeable Ca contents increased lower than the critical value. Exchangeable Mg content is lower than the critical value of a downward trend. The effective B content is higher than the threshold upward trend, available Fe, effective of Mn available Cu and available Zn content higher than the critical value of a downward trend, in which the effective Mn content exceeded. |
