摘要
通过对太原市不同土壤类型1 984个耕层土壤样本的调查分析,研究了太原市土壤中交换性镁的含量及分布状况,结果表明,全市土壤交换性镁含量平均为165.21 mg/kg,最高含量为993.83 mg/kg,最低含量为13.82 mg/kg;不同土壤类型交换性镁含量高低依次为:潮土>石灰性褐土>粗骨土>褐土>褐土性土>淋溶褐土。
Investigation of 1984 soil samples in plough horizon in Taiyuan region showed that the average content of exchangeable magnesium is 165, 21 mg/kg, with the minimum 13.82 mg/kg and the maximum 993.83 mg/kg. The exchangeable magnesium content varies in different types of soils, the consequent succession is as followed： alluvial soil 〉 calcareous cinnamon soil 〉 skeletal soil 〉 cinnamon soil 〉 infant cinnamon soil 〉 leaching cinnamon soil. It provides the information to apply magnesium fertilizer rationally for Taiyuan Region.
