| 摘 要： | 在陕西省17种土壤类型中,选取了其中分布面积较广且具有代表性的11种耕地土壤类型,共采集耕层土壤样品159个,利用柠檬酸浸提法分析土样中的有效硅含量。结果表明,陕西省土壤有效硅平均含量为390.99mg/kg,最高为980.32 mg/kg,最低为74.5 mg/kg;土壤有效硅的水平分布特征总体上呈现北低南高,在陕南地区呈现西高东低的特征。土壤有效硅含量与土壤有机质、土壤全氮、全磷的含量成正比关系,与土壤全钾的含量关系不明显。

| Abstract: | The 11 types of soils were selected from all of 17 types of soils in Shaanxi according to the distributing
area and the representative. We have gather about 159 soil samples from all the province. The result of analysis
showed that the average content of available silicon in soils in Shaanxi Province is about 390. 99 mg/kg, the high-
est 980. 32 mg/kg, The lowest 74. 5 mg/kg. The variational tendency of content of available silicon in soils in-
creases from the north to the south and decreases from the east to the west. The content of available silicon is di-
rect correlation to organic matter, total nitrogen,total phosphorus in soil, is irrelevant to total potassium in soil in
the south of Shaanxi. |
