摘要
海南岛主要植枝区的土壤肥力状况差异极大，其中大部分桉林分布在贫瘠的褐色砖红壤、燥红土和滨海砂土上，这些土壤有效肥力和潜在肥力都不高。在热带地区营造桉林后，林地土壤肥力下降，土壤明显酸化。初步拟定了桉树速生丰产的土壤肥力指标，供桉树配方平衡施肥参考。
Eucalyptus planting sites in Hainan Island have a much highly significant difference in soil fertility. Most of the Eucalyptus plantations are distributed on poor brown laterite, dry red soil and coastal sandy soil. The available or potential fertility is low on these soils. Planting of Eucalyptus in these area resulted in decline of soil fertility and noticeable acidification of the soils. Some initial soil fertility indexes were suggested for rapid growth and high yield of Eucalyptus and could be used as reference for applying balanced fertilizer to Eucalyptus.
