摘要
本文综述了长期定位试验下不同施肥处理对土壤中微量元素Fe、Mn、Cu、Zn的含量变化及其形态组成的影响,同时也简要介绍了不同耕作措施及不同耕作制度下微量元素Fe、Mn、Cu、Zn含量变化。
The research progresses on the content and forms of microelement-Fe, Mn, Cu, Zn in soil in different fertilization in long-term experiment were summarized, and the content of microelement-Fe, Mn, Cu, Zn in different cultivating and planting pattern were briefly introduced.
