摘  要：
【目的】调查海南省主要油棕园土壤养分状况,通过评价土壤肥力,为海南省油棕种植区土壤养分的合理、科学管理提供依据。【方法】选择海南省海口、陵水、儋州、定安、文昌等市县的油棕种植园采集油棕根际表层(10～20cm)土壤,测定土壤pH、有机质、碱解氮、有效磷、速效钾、交换性钙、交换性镁、有效铜、有效锌、有效铁、有效锰、有效硼等12个指标,并进行差异显著性分析。【结果】调查样点的pH较适合油棕的生长;油棕根际土壤的有机质和氮磷钾等主要营养含量较高的为儋州市和定安县,其次为海口市,最低的为文昌市和陵水县;海南省油棕园土壤交换性钙普遍供应充足,交换性镁除文昌市椰子所含量较低外,其他调查样点不存在缺乏现象;调查样点土壤不缺乏铜、锌、铁3种微量元素,除文昌市和陵水市土壤有效锰含量较低外,其他样点处于中等以上含量水平;整个海南省调查样点油棕地存在缺硼现象。【结论】应通过施肥,提高文昌市和陵水县土壤肥力水平,满足该地区油棕生长的需要;重视硼肥的施用,以改善海南省油棕园缺硼现象。

摘  要：
Objective Soil nutrient status of major oil palm plantations in Hainan Province was investigated to provide references for appropriate and scientific management of soil fertility in the above-mentioned places. Method Rhizosphere surface soils around oil palm (10-20 cm)were collected in Haikou,Lingshui,Danzhou,Dingan and Wenchang. Twelve indexes including soil pH,organic matter content,nitrogen content,phosphorus content,available K,exchangeable Ca,available Mg,available Cu,effective Zn,effective Fe,effective Mn,effective B were detected,and their differences were comparatively analyzed. ResultSoil pH of the investigated spots was suitable for the growth of oil palm. The main nutrition of organic matter content,ni-trogen,phosphorus and potassium followed the sequence:Danzhou and Dingan>Haikou>Wenchang and Lingshui. Exchangeable calcium was inadequate in Hainan. Exchangeable Mg in all the sites except Wenchang was above critical level. Three trace elements including Cu,Zn and Fe were immense. Effective Mn in all sites except Wenchang and Lingshui was above critical level. All the sites in Hainan Province were lack of B elements. Conclusion On the whole,reasonable fertilizing measures were needed to boost soil fertility. To meet the growth demands of oil palm,B fertilizer should be centered to supplement B in all oil palm plantations of Hainan Province.
