为探讨不同施肥处理对侵蚀性红壤的修复效应,研究了施化肥(NPK)、化肥+有机肥(NPKM)、化肥+土壤调理剂2号(NPKR2)与不施肥(CK)处理对不同母质发育的侵蚀性红壤酸性和交换性能的修复效应。结果表明:NPKM及NPKR2处理均可明显提高各种酸性土壤的pH缓冲能力,NPK处理效果则不明显;NPKR2可改良和降低土壤酸化程度,NPKM处理则只能增大土壤的pH缓冲容量,对改良土壤酸化的效果不显著;NPKM处理可提高土壤有机质含量,但土壤有机质含量与土壤pH缓冲能力不成正比;各施肥处理均能显著降低板页岩红壤、网纹层红壤和均质层红壤铝离子的活性,但只有NPKR2处理能明显降低花岗岩红壤的铝离子活性,其他施肥处理的效果...

In order to understand the remediation effect of different fertilization structure on eroded soil,a pot experiment was conducted to investigate the restoration effects of Chemical fertilizer（NPK）,NPK ＋ Organic fertilizer（NPKM）,NPK＋ Soil conditioner R2（NPKR2）,No fertilization（CK） on the acidic and exchange properties of eroded red soil which developed from different parent materials.The results indicated that treatments of combined application of organic and inorganic fertilizers（NPKM） and combined application of inorganic fertilizer...
