摘　　要：对砖红壤施用不同的改良剂,进行1a的大田试验后,测定土壤的阳离子交换量、有效阳离子交换量、盐基离子总量以及盐基饱和度来研究不同土壤改良剂对酸性土壤交换性能的影响。结果表明:施用滤泥(40t/hm2)、石灰(2.5t/hm2)以及在施用一定量的羊粪(20t/hm2)基础上施用中量(40t/hm2)或者高量(60t/hm2)膨润土的复合改良剂是有效提升酸性土壤交换性能、增加土壤盐基总量与盐基饱和度的优良措施。Latosol was treated with various soil amendments, and one year after the field trial it was determined in terms of soil cation exchange capacity, effective cation exchange capacity, soil exchangeable base-cation concentrations and base saturation to observe the effect of different soil amendments application on the latosol exchangeable property. The results showed that application of filtering mud（40 t/hm^2）, lime （2.5 t/hm^2）, compound soil amendment containing the medium（40 t/hm^2） or high（60 t/hm^2） amount of bentonite based on the application of some （20 t/hm^2） goat manure was a good measure which could effectively upgrade the soil exchange property, increase the soil exchangeable base cation concentrations and base saturation.
