红壤产生于热带和亚热带雨林、季雨林或常绿阔叶林植被下，是发生脱硅富铝过

Red soil is produced in tropical and subtropical rainforests, monsoon forests or evergreen broad-leaved forest vegetation. It is a red-acidic and highly unsaturated salt-bearing bauxite that has undergone a desiliconized aluminum-rich process and biological enrichment. Its main feature is the lack of alkali metals and alkaline earth metals, but it is rich in iron and aluminum oxides and shows an acid red color.

Red soil is produced under tropical and subtropical rainforests, seasonal rainforests or evergreen broad-leaved forest vegetation, and is a red acidic and highly unsaturated iron bauxite developed by the desilicon-rich aluminum process and biological enrichment. Its main characteristics are the lack of alkali metal and alkali soil metal, and rich in iron, aluminum oxides, acidic red.

Red soil, which is produced under the vegetation of tropical and subtropical rain forests, seasonal rain forests or evergreen broad-leaved forests, is a red, acid and highly unsaturated ferraluminite developed by the process of desilication and aluminum enrichment and biological enrichment. It is characterized by the lack of alkali metals and alkaline earth metals, and rich in iron and aluminum oxides, showing acid red.<br>
