| 摘 要： | 研究了3种不同母质发育的红壤中电荷的差异,比较了不同母质对电荷的影响。结果表明:3种母质发育的红壤中,紫色土发育的红壤中全部负电荷含量明显高于花岗岩发育的红壤和第四纪红色黏土发育的红壤;第四纪红色黏土发育的红壤中正电荷的含量明显高于花岗岩发育的红壤和紫色土发育的红壤;第四纪红色黏土发育的红壤、花岗岩发育的红壤和紫色土发育的红壤中正电荷与pH呈显著性负相关;第四纪红色黏土发育的红壤正电荷与有机质呈显著负相关,花岗岩发育的红壤和紫色土发育的红壤中正电荷与有机质含量呈显著正相关;第四纪红色黏土发育的红壤和紫色土发育的红壤正电荷与黏粒含量呈一元二次线性关系,花岗岩发育的红壤正电荷与黏粒含量呈极显著负相关;紫色土发育的红壤吸附的NH4+-N含量最高,第四纪红色黏土发育的红壤吸附的NO3--N含量最高。通过对3种母质发育的土壤电荷特性的研究,可为不同母质的红壤进行合理施肥与管理提供科学依据。

| Abstract: | The different charge properties among three kinds of red soil derived from different parent materials were studied and the influences of different parent materials on soil charge were compared.The results showed that the total negative charge(CECpH8.2) in purple soil was higher than that in Quaternary red clay(Q-red clay).The positive charge(AEC)in Q-red clay was higher than those in the purple soil and the soil from granite.AEC in three kinds of red soils had significantly negative correlation with pH.AEC ... |
