岩石、土壤、农作物关系浅议

表土(土壤)、母质、岩石三者之间化学组成变化很小,土壤的化学组成完全继承了母质、岩石的特性。从不同地域作物生长品质的差异的大量事例表明岩石、土壤、农作物之间关系密切。土壤养分绝大部分来自岩石,研究土壤肥力,就必须研究生长土壤的岩石。农业地质学所面临的一个任务是研究土壤与围岩的关系,土壤与农作物的关系,其发展前景无限美好。

A SEQUENCE OF ROCK, SOIL AND CROP

Surface soil (soil), mother material and rock are almost common in chemical composition but the first succeeds to the latter two in terms of chemical composition. A fact that growth quality of crops display a great differences depending on different geographic regions indicates that growth of crops has a close tie with characteristics of soil and rock. Nutrients of soil are mostly sourced from rock so the rock bringing up the soil must be studied before fertility of soil is studied. Agricultural geology takes as a pressing task researching on relation of soil to its mother rock and of soil to growth of crops, hence enjoying excellent development prospects.
