摘要
论述了锰元素的地球化学特征和分布 ,农作物与锰元素的关系以及锰元素有效态含量的制约因素 :土壤的锰含量、土壤的酸碱度、土壤的氧化还原环境、土壤的有机质含量。
The restrictive factors of global chemical characteristics and distribution of manganese element, the relationship between crop and Mn element, and effective state content of the same are discussed, These restrictive factors include Mn content in soil, the acidity and alkalinity of soil, oxidation and reduction environment and organic matter content of soil.
