| 摘要: |
| 采用典型样地调查的方法，以韶关市曲江区国有小坑林场国家油茶良种基地为基础，系统研
究了全域范围内不同地点、海拔、坡位和土层的自然含水量、容重、pH 值、土壤有机质、大中微量元素
含量等。结果显示韶关市小坑镇油茶林土整体土壤 pH 值在 4.5~6.5 之间，属酸性土壤，土壤有机质平均
含量为 12.68 g?kg-1，属于低水平。土壤全氮和碱解氮含量低，全磷含量整体缺乏，有效磷含量极度缺乏，
速效钾含量偏低。该试验区域的交换钙和交换镁都处于极度缺乏的水平，有效硼的含量匮乏，有效铜和
有效锰含量中等，有效锌含量丰富，有效铁的含量最高。需要补充适量的氮、磷、钾等大量元素及钙、
镁等中量元素和微量元素硼。 |

| Abstract: |
| Using the method of typical sample survey，the natural water content, unit weight, pH value,
soil organic matter and mass-medium-trace elements contents of different locations, elevation, slope position and
soil layer were systematically studied in Xiaokeng National Camellia oleifera base and other Camellia plantations
in this town. The analysis results showed that the soil of Camellia Forest Land in Xiaoken town was acidic and
the organic content was relatively low. It was necessary to supplement a proper amount of nitrogen, phosphorus,
potassium, calcium, magnesium and boron in the Camellia Forest Land in this region. |
