摘要
通过对全省不同土壤类型１１０５个耕层土壤样本的调查分析，明确了全省土壤交换性镁含量平均为０．４８ｇ／ｋｇ土，最低０．０２ｇ／ｋｇ土，最高２．４１ｇ／ｋｇ土，不同土类交换性镁含量高低依次为潮土＞盐土＞砂姜黑土＞褐土＞粗骨土＞棕壤。分析了不同地貌类型区土壤交换性镁含量及分布规律，为全省不同地区重视和合理应用镁肥提供了依据。
Investigation of 1105 soil samples in plough horizon in Shandong Province showed that the exchangeable magnesium content is 0.48g/kg,with the minimum 0.02g/kg and the maximum 2.41g/kg.The exchangeable magnesium content varies in different type of soil,the consequent succession is as followed:alluvial soil>saline soil>black clay soil>brown soil>coars soil>cinnamon soil.The exchangeable magnesium content and distribution in different land-form areas were also analyzed.
