摘　　要：研究了长期(1996～2008年)施用有机肥(M)、有机肥+有效菌剂(BM)、有机肥+有效菌剂+微量元素(BMT)、化肥(F)以及化肥+微量元素(TF)对红壤旱地土壤有机质、养分和CEC的影响。结果表明:长期定位施用有机肥的处理土壤有机质含量均显著积累,从1996年的8.91 g/kg上升到2008年的21.55 g/kg,全氮、全磷、水解氮、有效磷、有效钾和CEC含量升高,土壤全钾含量变化趋于平缓,甚至有降低趋势。说明红壤旱地施用有机肥以及有机肥配施有效菌剂更有利于土壤养分积累。The paper studied the effects of long-term（from 1996 to 2008） located fertilization on the contents of organic matter,nutrient and CEC in upland red soil,and the applied fertilizers included organic manure（M）,organic manure ＋ effective microorganisms（BM）,organic manure ＋ effective microorganisms ＋ microelements（BMT）,chemical fertilizer（F） and chemical fertilizer ＋ microelements（TF）.The results showed that： in the treatments of long-term located application of organic manure（M,BM and BMT）,the soil organic matter content obviously increased from 8.91 g/kg in 1996 to 21.55 g/kg in 2008,the contents of total nitrogen,total phosphorus,hydrolysis nitrogen,effective phosphorus,effective potassium and CEC all increased,and the change in the content of total potassium was steady,even had a little reducing tendency.It indicated that applying organic manure or organic manure combined with effective microorganisms was beneficial to the accumulation of soil nutrients.
