长期定位施肥对土壤铜、锌形态转化及其空间分布的影响
Effects of Long-term Located Fertilization on the Forms Transformation and Spatial Distribution of Cu and Zn in Soil
摘要
Abstract
The BCR continuous extraction was used to research the soil Cu and Zn contents change and its spatial variability after 31-year fertilization treatments on Shenyang Agricultural University brown earth long-term localization experimental field.The experimental results showed that compared with the baseline,the contents of the water soluble Cu,the weak acid soluble Cu and residual Cu decreased,the contents of oxidizable Cu and reducible Cu decreased in fertilizer area while in organic fertilizer area the trend was opposite;except residual Zn,the contents of other forms increased.The distributions of Cu forms were different in different treatments in topsoil（0-20 cm）,residual Zn was the main forms.As for the spatial distribution,with the deepen of soil,the contents of the weak acid soluble,oxidizable and reducible Cu,Zn reduced.Reducible Cu gave the greatest contribution to available Cu and oxidizable Zn gave the greatest contribution to available Zn.关键词
