| 摘 要： | 目的]了解毛鸡骨草GAP基地土壤肥力现状,以及土壤中氮、磷、钾3要素的自然供给能力。方法]运用改进的内梅罗(Nemoro)综合指数法对基地土壤肥力进行综合评价,并通过施肥试验研究了基地土壤中氮、磷、钾3要素的自然供给能力。结果]土壤综合肥力系数为1.21,毛鸡骨草产量对土壤的依存率为40.90%。结论]基地土壤综合肥力属"一般"等级,土壤供应氮、磷、钾的能力分别处于"低"、"高"、"中"等级,较低的土壤含氮量是该基地的主要养分限制因子。

| Abstract: | Objective] The aim of this paper was to investigate the status of soil fertility and the ability of soil nutrient supply.Method] Soil fertility was diagnosed and evaluated with modified Nemoro Index.The soil N,P and K supplying capacity in GAP cultivation base of Abrus mollis Hance was studied by fertilization experiment.Result] The result indicated that the comprehensive coefficient of the soil fertility was 1.21.The relying ratio of Abrus mollis Hance yield on soil was 40.90%.Conclusion] The soil fertility in GAP cultivation base of Abrus mollis Hance was in the category of "general".The soil N,P and K supplying capacity fell in the categories of " low","high" and "medium",respectively.Low soil nitrogen content was the major nutrient limiting factor in this base. |
