以潮土和棕壤土为研究对象，通过添加不同量未活化和活化的风化煤腐植酸，对比研究了2种腐植酸对土壤肥力和理化性状的影响。试验结果表明：单施未活化的风化煤腐植酸和活化的风化煤腐植酸对土壤中全氮含量无明显效果，但可以活化和释放土壤中难溶性磷、矿物态钾、缓效性钾，使其转化成速效磷和速效钾；施用3个月后，2种土壤中速效磷、速效钾、阳离子交换量、水稳性团聚体均有不同程度的增加。其中，碱活化的风化煤腐植酸对土壤理化性状具有良好的影响，可使2种土壤中的速效磷含量、速效钾含量、阳离子交换量、水稳性团聚体数量分别增加24.80～130.87 mg/kg、43.01～113.19 mg/kg、8.87～9.49 cmol/kg、8.01%～18.84%。

Taking alluvial soil and brown soil as the research object and by adding different addition quantity of unacti-vated and activated weathered coal humic acid, the effects of two humic acids on soil fertility and soil physicochemical properties were comparatinely studied. The results showed that there was no signiifcant effect on total nitrogen content in soil with application of unactivated and activated weathered coal humic acid. But the dissolved phosphorus, mineral potassium, slowly available potassium were activated and released. After three months, available phosphorus, available potassium, cation exchange capacity and water stable aggregate were all improved to different extents respectively in two soils. Among them, the alkali-activate weathered coal humic acid had the good inlfuence on soil physicochemical properties. It could make available phosphorus content increased by 24.80~130.87 mg/kg, available potassium content increased by 43.01~113.19 mg/kg, the cation exchange capacity increased by 8.87~9.49 cmol/kg and the water stable aggregate increased by 8.01%~18.84%in two kinds of soil.
