摘要:

对陕西省洛川塬苹果林地土壤的质地、有机质、有效磷、速效钾、速效氮、pH值、容重、碳酸钙等进行了分析和研究，并与第二次全国土壤普查的资料进行了对比，结果表明：农业耕地改苹果林地后，随种植年限的增加，土壤肥力质量发生变化，表现为有效磷和有机质含量增加，速效钾、速效氮含量降低．利用内梅罗模型对苹果林地土壤质量进行综合评价，得出土壤肥力系数在1.13～1.39之间，土壤肥力一般．

Abstract:

Soil texture, organic matter, available phosphorus, available potassium, available nitrogen, pH value, bulk density and calcium carbonate of apple soil were analyzed, and they were compared with the materials collected from the second nation-wide soil survey in Luochuan tableland, Shaanxi province. The results show that obvious changes of soil fertility quality take place with the increase of cultivation period when the cultivated land transmitted to apple soil. The contents of organic matter and available phosphorus increase, whereas, the available potassium and available nitrogen decrease. The soil quality of apple soil was evaluated with the Nemoro formula, the results indicate that soil fertility quality index is 1.13～1.39, and the soil fertility is medium.
