Investigation and evaluation on soil nutrition of oil palm plantations in Hainan Province
摘要
Abstract
[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.[Result]Soil pH of the investigated spots was suitable for the growth of oil palm.The main nutrition of organic matter content,nitrogen,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 element~ [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.关键词
