微量元素的研究和在农业及畜牧业中的应用,已有近五十年的历史。随着科学研究的深入,土壤中微量元素含量、分布、形态、转化和移动的规律性,影响土壤中微量元素可给性的因子,微量元素的生理生化机理都已逐渐明确,为动物和植物所必需的微量元素也逐渐被发现而增多。目前,世界各国都对微量元素进行了大量研究工作,他山之石可以为错,今将国外微量元素工作情况作简单介绍,以供参考。由于篇幅所限,只介绍少数国家情况,内容也有所偏重。西德着重介绍土壤中微量元素研究情况,英国和荷兰介绍微量元素在农业和畜牧业中应用的概况和有关的总结,苏联介绍微量元素研究工作的组织和计划情况,东德介绍微量元素含量图和微量元素肥料使用情况以及增产幅度,美国介绍缺乏微量元素的土壤和面积,
Trace element research and its application in agriculture and animal husbandry has been nearly 50 years of history. With the deepening of scientific research, the content and distribution of trace elements in soil, the rules of transformation and movement, the factors that affect the availability of trace elements in soil, and the physiological and biochemical mechanisms of trace elements have gradually become clear, The necessary trace elements are also gradually discovered and increased. At present, all the countries in the world have carried out a great deal of research on trace elements. The stone of other hills can be wrong. Now we briefly introduce the work of foreign trace elements for reference. Due to space constraints, only a few countries introduced the situation, the content is also somewhat biased. West Germany focuses on the study of trace elements in soil, the introduction and summary of the application of trace elements in agriculture and livestock husbandry in Britain and the Netherlands, the organization and planning of the research on trace elements in the Soviet Union, the introduction of trace element content in East Germany And the use of trace element fertilizers and yield increase, the United States introduced the lack of trace elements of soil and area,
