摘　　要：在江西省内樟树主产区安福县选取45个代表性人工林土壤样品分析的结果表明,选取的3个樟树人工林土壤呈酸性和强酸性,土壤风化淋溶程度高;3个人工林区及同一个种植区不同土层深度的土壤容重和孔隙状况均存在一定差异;绝大部分土壤有机质含量均在20 g/kg以下,处于低量劣质水平;不同土层的土壤全氮和全磷含量极低,全钾含量则为中等至稍丰水平,大部分土壤全磷含量均为极缺水平;各层土壤中交换性钙、有效锌和有效铁含量较为丰富,交换性镁和有效铜含量为中等水平;有效猛含量一般,有效磷含量为缺乏水平;速效钾含量极为缺乏,土壤整体肥力处于中等偏下水平。In order to understand the soil fertility status of camphor tree plantation areas in Jiangxi Province,45 representative plantation soil samples were selected in Anfu County,the main producing area of Camphor tree plantation in Jiangxi Province.The results showed that the soil of the three camphor plantation forests was acidic and strongly acidic,and the soil weathering and leaching were high.There are some differences in soil bulk density and pore conditions in three camphor plantation forests,and there are also some differences in soil bulk density and pore conditions in different soil depths in the same plantation area.The content of most soil organic matter is below 20 g/kg,which is at the level of low quality.The contents of total nitrogen and total phosphorus in different soil layers are extremely low,while the content of total potassium is moderate to slightly abundant,and the content of total phosphorus in most soils is extremely deficient.The content of exchangeable calcium,available zinc and available iron in each layer of soil is relatively rich;the content of exchangeable magnesium and available copper is medium level,the content of available copper is general,the content of available phosphorus is deficient,the content of available potassium is extremely deficient,and the overall soil fertility is at the lower level of medium.
