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,明确了全省土壤有效硫含量平均为4731mgkg土,最低219mgkg土,最高799mgkg土,不同土类有效硫含量高低依次为潮土>砂姜黑土>盐土>褐土>棕壤>粗骨土。分析不同地貌类型区土壤有效硫含量及分布规律,为全省不同地区硫肥的合理应用提供了依据。
Investigation of 1105 soil samples in plough horizon in Shandong Province showed that the average available sulphur content is 47.31mgkg,with the minimum 2.19mgkg and the maximum 799mgkg.The sulphur content varies in different type of soil,the consequent succession is as followed:alluvial soil>black clay soil >saline soil>brown soil>cinnamon soil>coars soil.The available sulphur content and distribution in different land-form areas were also analyzed.
