为了解澄城县果园土壤养分分布状况及合理制定施肥方案，以陕西省澄城县86户果农苹果园土壤为研究区，对果园土壤的有机质、有效磷、全氮及速效钾的含量及变异情况进行分析。结果表明：澄城县苹果园土壤有机质和全氮含量处于缺乏状态，而速效钾处于丰富状态，有效磷处于中等和丰富状态。各乡镇4种养分含量变异程度为有效磷（44.06％）＞速效钾（24.52％）＞有机质（16.39％）＞全氮（13.63％），除交道镇土壤有机质和全氮、寺前镇土壤速效钾的变异系数表现为弱变异外，其余乡镇的4种养分分布均表现为中等变异。

To make reasonable fertilization scheme based on testing nutrient distribution of soil at apple orchard ,soil among the 86 apple orchards at ChengCheng county was choosed as the research area and these elements were determined ,including organic mat-ter,available phosphorus ,total nitrogen and available potassium content and variation level.Results show that soil organic matter and total nitrogen content are in the lack of stater ,rapidly-available potassium in the abundant state ,and the effective phosphorus in the medium or the richstate at Chengcheng county.The variation level of nutrients from large to small for these towns were available phosphorus(44.06%),rapidly-available potassium(24.52%),organic matter(16.39%),total nitrogen(13.63%).And apart from the rapidly-available potassium of soil at Siqian town and soil organic matter and total nitrogen content at Jiaodao town are weak vari -ation.the nutrient distribution are characterized by medium variation for the rest four of villages and towns .
