摘  要:
以长治市左权县东隘口村土壤为研究对象,将48个分别来自玉米地、蓖麻地、谷子地、药材地内的不同土壤类型样品,用原子吸收分光光度计进行有效镁含量的检测。结果表明,试验区内,土壤有效镁含量处于中等水平,且有效镁含量与电导率呈现正相关关系。不同作物下的土壤有效镁含量无显著性差异,而在不同土壤类型间差异性显著。土壤缺镁时,可以施用硫酸钾镁。

摘  要:
Taking the soil of the East Aikou Village, Zuoquan County as the research object, 48 samples of different soil types from corn, canola, corn, herbs fields, was detected separately for the effective magnesium content by atomic absorption spectrophotometer methods. The results showed that in the test zone the soil effective magnesium content was the medium level, and the effective magnesium content presented positive correlation with electrical conductivity. The effective magnesium content of soil under different crops were no significant difference, but the differences between different soil types were significantly. When soil was short of magnesium,magnesium potassium sulfate could be applied.
