| 中文摘要: |
| 根据土壤地球化学调查结果，研究了仁寿地区优产棉、粮等农作物生长环境的地球化学特征，结果表明，区内元素分布与地质背景、地貌景观、土壤属性、人类活动等因素有关。土壤中营养元素产榔棉生长最优地质背景。研究评价结果为本区农业生产合理区划、种植、土壤改良、科学施肥等提供了重要的地球化学依据。 |
| 英文摘要: |
| According to geochemical survey, geochemistry of soil for high-quality grain and cotton growth environment in Renshou County, Sichuan Province, is studied. It is indicated that the distribution of elements is related to geological background, geomorphologic landscape, soil attribution, and human activities etc. Except for lack of Mo and P, the other nutrition elements are adequate or abundant. The nutrition elements vary in different types of soil. The Penglaizhen Formation (J3p) of Jurassic provides favourable geological background for growth of high-quality grain and cotton. The researching results can provide the important geochemical evidence for rational agricultural programming, planting, soil improvement and scientific fertilization. |
