摘    要:采用室内培养实验的方法,控制典型黑土样品的酸碱度值,探讨典型黑土中Cu、Zn、Mn、P和Fe等营养元素有效态含量与pH值的关系。结果表明:pH值变化0.5个单位左右,有效态铜含量变化约0.5~1倍;有效态锰含量变化约3~5倍;有效态锌含量变化9~15倍之多;有效态磷含量变化约1.5~2倍;有效态铁含量变化约3~4倍。说明精确掌握土壤的酸碱度值对于土壤诊断、合理施肥、提高作物产量和实现土地的可持续利用都具有重要的理论与实践意义。

关 键 词:典型黑土  营养元素  元素有效态含量  土壤pH值

Abstract:Based on the method of incubation test by controlling the pH of typical black soil samples, the relationship of soil pH and the effective content of nutrient elements:Cu, Zn, Mn, P and Fe was studied. The results show that following pH changing 0.5 unit, the ratio of high value to the low value of the effective Cu content is about 0.5 to 1 in typical black soil, the ratio of effective Mn content is about 3 to 5, the ratio of effective Zn content is about 9 to 15, the ratio of effective P content is about 1.5 to 2, and the ratio of effective Fe content is about 3 to 4. The findings Suggest that it is important fo know Soil pH values in terms of proper fertilization, high yield and sustainable use of Land.
Keywords:Typical black soil  Nutrient elements  Effective elements content  Soil pH value
