山东省土壤有效硫含量及分布

Available Sulphur Content in Soil and Distribution in Shandong Province

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４７３１ｍｇｋｇ土，最低２１９ｍｇｋｇ土，最高７９９ｍｇｋｇ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 47.31mgkg,with the minimum 2.19mgkg and the maximum 799mgkg.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.
