清西陵地区土壤养分和酸碱状况的研究

为研究清西陵地区土壤养分和酸碱状况，对不同地形及不同母质母岩上发育的典型土壤剖面分层采集土样，进行室内分析。结果表明：中山、低山石灰性母质土壤呈微酸性，有机、无机养分丰富。丘陵区石灰性母质土壤呈微碱性，非石灰性母质土壤呈中性偏酸，土壤养分总体水平偏低，但不同剖面存在一定差异。

STUDY ON SOIL NUTKITION STATUS AND SOIL ACIDITY-ALKALINITY IN QING XILING REGION

To study the soil nutrition status and soil acidity-alkalinity in Qingxiling region,soil samples collected by larger in the typical soil profiles on different parent materials andparent rocks were analyzed in laboratory.The results showed that the soil on calcareousparent material in middle mountain and low mountian was acidulous and rich in organicand inorganic nutrients.The soil on calcareous parent material in hilly region wasalkalescent and the soil on other parent materials was neutral to acidulous.The soil nutri-tion in hilly region was generally rather low with certain difference in different soil profiles.
