摘　　要：应用土壤养分状况的温网室调查方法研究了江西省九江市庐山区海会镇和永修县军山镇两地的油茶(Camellia oleifera Abel.)林土壤养分状况。结果表明,两地的油茶林土壤对P、S和K都具有较强的吸附固定能力,而对Mn和Cu的吸附固定能力较弱;军山油茶林土壤(以下简称军山土)对Zn的吸附固定明显高于海会油茶林土壤(以下简称海会土);对B的吸附只在军山土中出现。盆栽试验中养分亏缺顺序海会土为Ca、P、N、Mo、K、Mg、Cu、Zn,军山土为Ca、P、N、K、Mg;Ca、P、N、K、Mg均为两地油茶林土壤的限制因子;Mo作为海会土中的限制因子,其缺乏程度也较重。实验室测定结果与盆栽试验结果有较好的一致性。The soil nutrients of Camellia oleifera Abel.plantations of Haihui town and Junshan town in Jiangxi province were studied using greenhouse/screenhouse technique.Results showed that the soil adsorption capacity of P,S and K was higher than that of Mn and Cu in the both areas.The Zn adsorption extent of the soil from Junshan was higher than that from Haihui.The adsorption of B only appeared in soil from Junshan.The nutrients deficiency of the soil in pot experiment was in the order of Ca,P,N,Mo,K,Mg,Cu,Zn in the soil from Haihui and Ca,P,N,K,Mg in the soil from Junshan.Ca,P,N,K,and Mg were limiting factors for both soils.Mo was the limting factor for the soil from Haihui.The results of pot experiment were consistent with those in laboratory.
