对广西各类土壤布点取样测试，广西土壤全钼含量为０．２３－５．００ｍｇ／Ｋｇ，平均１．０７ｍｇ／Ｋｇ。不同母质发育的土壤全钼含量有很大差异，第四纪红土和石灰岩发育的土壤，全钼含量最高，紫色岩和砂页岩最低。全区土壤有效钼含量为痕迹－０．６４５ｍｇ／ｋｇ，平均０．０９３ｍｇ／ｋｇ。影响土壤有效钼含量的因素有土壤母质、ｐＨ值、有机质和土壤的利用方式。 Guangxi all kinds of soil distribution sampling test, Guangxi soil total molybdenum content of 0.23-5.00mg / Kg, an average of 1.07mg / Kg. The content of total molybdenum in soils with different parent materials is quite different. The Quaternary laterite and limestone developed soils have the highest total molybdenum content and the lowest in purple and sand shale. The soil available molybdenum content traces of -0.645mg / kg, an average of 0.093mg / kg. The factors influencing the effective molybdenum content of soils are the ways of using soil parent material, pH value, organic matter and soil.
