| 摘 要： | 相同含量的元素在不同理化性质(土壤的酸碱度、有机质等)的土壤中,可表现出完全不同的地球化学行为,从而影响元素的转化和作物对元素的吸收。本文通过分析土壤与农作物介质中元素的生态地球化学效应,对根系土-玉米籽实、根系土-小麦籽实之间元素的迁移转化影响因素进行了研究,发现有机质、酸碱度与土壤中各元素之间有一定的相关性,其成果对于区域土壤地球化学资料在农业营养施肥、环境质量评价等方面具有重要的指导意义。

| Abstract: | The same content of elements in the soils with different physical and chemical properties (pH and organic matter of soil) can show completely different geochemical behavior. It will affect the transformation and crop absorption of elements. Based on the analysis of eco-geochemical effects of elements in soil and crop medium, the factors affecting the migration and transformation of elements between root soil-corn seed and root soi-wheat seed have been studied. It is found that there is a certain correlation between organic matter, pH and various elements in soil. The results have important guiding significances for the application of regional soil geochemical data in agricultural nutrition, fertilization, soil fertility and environmental quality assessment. |
