中文摘要	通过典型采样分析，研究侏罗纪沙溪庙组（Ｊ２ｓ）、遂宁组（Ｊ３ｓ）、蓬莱镇组（Ｊ３ｐ）和白垩纪城墙岩群（Ｋ１ｃ）、夹关组（Ｋ２ｊ）五种紫色土主要肥力要素的剖面分配特征。以黄壤作对比，对上这紫色土的肥力要素进行统计分析，评价紫色土的肥力状况与肥力潜力。结果表明，紫色土矿质养分含量高，土壤肥力高于黄壤；紫色土剖面有同质、Ｎ呈表土〉母质〉母岩的正向分异，Ｐ也基本表现正向分异的特点，紫色土全Ｋ表现逆向分异趋势。田间生物试验结果表明，富含未风化母岩（紫色页岩）的紫色土玉米产量达到对照紫色土的８０％，土壤有机质及Ｎ素缺乏明显，施用有机质（３００００ｋｇ／ｈａ）和Ｎ（９０ｈｇ／ｈａ）、Ｐ（１８ｋｇ／ｈａ），玉米产量与熟化紫色土产量相当，表明紫色页岩是紫色土养分（尤其钾）补偿的重要而充足的库源，紫色土肥力潜力大，利用紫色页岩可快速培肥瘠薄紫色土。
英文摘要	Investigation, sampling and analyse were conducted to study nutrient distribution in soil profile of purplish soils of group J2s , J3s , J3p, K1c and K1j.Statistical analyses were used to assess soil fertility and fertility potentials compared with local landzonal soil (yellow soil).Results showed that fertility of purplish soil was higher than that of yellow soil. Organic matter and N in profile of purplish soil decreased from topsoil(A)to layer of paren t material(C) and purplish shale (rock R), wherever Kincreased .Results of field experiments on effects of fertility of purplish shale (J3p) showed , maize (Zea mays L.) yield of purplish soil with more than 55% of non-weathered rock was 80% that in ordinary pruplish soil (J3p). Furthermore, with application of organic manure (30 000 kg/ha), nitrogen (90kg/ha) and phosphorous (18kg/ha) to compensate the shortage of nutrient, the yield of maize in experimental purplish soil was almost the same as that of loamy purplish soil with high fertility. It was concluded that purplish shale was the most import ant and abundant nutrient (especially for K) source of purplish soil, and fertility potential of purplish soil was high. So, purplish shale could be utilized as resource to improve fertility of purplish soil.
