| 摘 要： | 目的]为改善土壤理化性质和促进农业可持续发展提供理论依据。方法]通过田间试验研究长期定位不同施肥对无石灰性潮土理化性质的影响。结果]单施有机肥处理的土壤含水量最高，CK的土壤含水量最低。施用有机肥处理的土壤容重较小，CK和无机肥处理的土壤容重较大。施用有机肥处理的土壤孔隙度显著高于不施有机肥处理和CK。施用有机肥、化肥处理和CK的土壤有机质含量分别约为原始土样的7．5、2．8和2．3倍。施用有机肥处理的土壤pH值提高了0．62，施用无机肥处理的土壤pH值降低。长期定位不同施肥对土壤速效养分氮磷钾含量的影响为：有机—无机肥料配施〉单施大量有机肥〉无机肥配施〉单施氮肥〉不施肥。结论]有机—无机肥料配施能有效改善无石灰性潮土的理化性质。
