| 摘 要： | 为了解广西山圩农场剑麻园土壤养分状况，采用常规方法，分析测定4个分场195个土壤样品。结果表明，土壤pH为4.78～8.21，平均为6.51，以中性土、弱酸性土为主，分别占47.7%、32.8%；有机质含量为14.74～45.33 g/kg，平均为25.61 g/kg，其中63.6%土壤样品处于中等水平；全氮含量为0.70～2.08 g/kg，平均为1.19 g/kg，处于中等偏低水平；土壤有效磷含量在2.348～77.524 mg/kg，变化幅度较大，平均为20.432 mg/kg，总体处于中等和中上水平；速效钾含量为25.882～681.619 mg/kg，平均为115.449 mg/kg，变化幅度较大，总体处于中等偏低水平。

| Abstract: | In order to investigate the nutrient status of sisal plantations in Shanxu Farm, 195 soil samples were collected and analyzed. The results showed that soil pH was between4.78 and 8.21 and average content was 6.51. The content of soil organic matter was between 14.74 g/kg and 45.33 g/kg and average contents was 25.61 g/kg. The content of total nitrogen was between 0.70 g/kg and 2.08 g/kg. The content of available phosphorus was between 2.348 mg/kg and 77.524 mg/kg. The content of rapidly available potassium was between 25.882 mg/kg and 681.619 mg/kg. The content of soil organic matter was medium. The content of total nitrogen and rapidly available potassium was medium or lower. The content of available phosphorus was medium or higher. |
