摘　　要：[目的]评价贵德县耕层土壤养分状况。[方法]采用常规方法,分析贵德县499个耕层土壤8项农化指标。[结果]贵德县耕层土壤平均有机质19.71 g/kg,全氮1.54 g/kg,全磷1.70 g/kg,碱解氮111 mg/kg,有效磷41 mg/kg,速效钾249 mg/kg,缓效钾1 029 mg/kg,pH 7.97。碱解氮、速效钾、缓效钾总体含量水平高;有效磷、有机质含量与丰缺指标比较,结果为中等水平。[结论]该研究可为耕地地力评价和测土配方施肥提供基础数据。[ Objective ] The objective is to evaluate soil nutrient situation. [ Method ] Eight agrochemical indexes of top layer soil content analysis of 499 samples were analyzed by conventional method. [ Result ] Top layer soil nutrient was as follows in Guide County： organic matter 19.71g/kg,total nitrogen 1.54 g/kg, total phosphorus 1.70 g/kg, available nitrogen 111 mg/kg, effective phosphorus 41 mg/kg, available potassium 249 mg/kg, slowly available potassium 1 029 mg/kg,pH 7.97. On the whole,nutrient level of available nitrogen,available potassi- um, and slowly available potassium of Guide County soil was high. Content of effective phosphorus, organic matter was at medium level compared with abundance and deficiency index. [ Conclusion] The research can offer based data for the cultivated land fertility evaluation and soil testing and fertilizer recommendation.
