摘要
通过对全省不同土壤类型１８１８ 个耕层土壤样本的调查分析，明确了全省土壤有效硅含量平均为２３４ｍｇ／ｋｇ 土，最低１５ ．４ｍｇ／ｋｇ 土，最高７７９ ．５ｍｇ／ｋｇ 土，不同土类有效硅含量高低顺序为褐土＞ 砂姜黑土＞ 盐土＞ 潮土＞ 棕壤＞ 粗骨土。
Investigation of 1818 soil samples in plough horizon in Shandong Province showed that the available silicon content is 234 mg/kg,with the minimum 15.4 mg/kg and the maximum 779.5mg/kg.The available silicon content varies in different type of soil,the consequent succession is as followed:Typic Haplustalfs>Vertic Haplustalfs>Typic Halaquepts>Typic Fluvaquents>Typic Paleustalfs>Lithic Ustochrepts.The available silicon content and distribution in different land-form areas were also analyzed.
