    Comprehensive evaluation of soil fertility in Huachonglou planting base

    • 摘要: 对光泽县崇仁村的华重楼种植基地土壤肥力状况进行调查分析,结果表明:所有样地土壤偏酸性,有机质和全钾含量较高;竹针混杂林样地的土壤全氮含量较低,所有样地土壤的全磷和速效钾含量较低;竹林、阔针混杂林、阔竹混杂林和竹针混杂林的土壤碱解氮含量偏低;针叶林、竹林、阔针混杂林、阔竹混杂林和竹针混杂林的土壤速效磷含量偏低。土壤肥力综合评价结果为常绿阔叶林、针叶林、阔针混杂林、阔竹混杂林的土壤肥力一般,竹林和竹针混杂林的土壤肥力处于贫瘠水平。

       

      Abstract: Soil fertility in Huachonglou planting base of Chongren Village of Guangze County was investigated and analyzed. The results showed that the pH value of soil samples from all sampling plots were acidic, the content of organic matter and total potassium were higher, the content of soil total nitrogen in the plots of bamboo-conifer forest was low; and the contents of total phosphorus and available potassium in all soil were low; and the content of soil alkali nitrogen of bamboo forest, broadleaf-conifer forest, broadleaf-bamboo forest and bamboo-conifer forest were low; the content of soil available phosphorus of coniferous forest, bamboo forest, broadleaf-conifer forest, broadleaf-bamboo forest, bamboo-conifer forest were also low. The results of comprehensive evaluation on soil fertility showed that the soil fertility in evergreen broad-leaved forest, coniferous forest, broadleaf-conifer forest and broadleaf-bamboo forest were normal, and the fertility in bamboo forest and bamboo-conifer forest were at poor level.
