研究了粤西南、云南、桂南、闽南、黔南和川东主要成土母质(岩)发育的砖红壤、赤红壤、红壤、黄壤、棕(红)色石灰土、黄壤的微量元素含量.玄武岩等基性岩发育的土壤含Cu、Zn、Co、Ni、V、Mn和Cr都较高,但含B较低.花岗岩等酸性岩发育的土壤,多数微量元素含量都较低.石灰岩等沉积岩发育的土壤含B都较高.同母质风化和发育程度较深的土壤,微量元素含量一般都较低;粘重土壤较轻质土壤的元素含量要高些.植物根系对分散在土体中的元素有富集作用.华南土壤中有效性B含量普遍较低,有些土壤的有较性Cu、Zn、Co、Ni含量也较低. The trace element contents of brick red soil, latosolic soil, red soil, yellow soil, brown (red) limestone soil and yellow soil were studied in southwestern Guangdong, Yunnan, southern Guangxi, southern Fujian, southern Guizhou and eastern Sichuan. The soils developed from basalts, such as basalts, contain Cu, Zn, Co, Ni, V, Mn and Cr in relatively high levels but low in B. Most soils with acidic rocks such as granites have low levels of trace elements such as limestone Sediments developed in the soil containing B are higher with the parent material weathering and development of the deeper soil, trace elements are generally low; viscous soils lighter elements of the soil is higher element content of plant roots dispersed in the soil The contents of available B in the soils of South China are generally low, and the contents of some Cu, Zn, Co and Ni in soils are also relatively low.
