二岩石、矿物与土壤母质的识别土壤是由成土母质发育来的,母质对土壤的组成、发育程度和肥力高低,常常有决定性的影响。在土壤普查中,母质因素常常是划分土属、土种、变种的依据。因此在普查土壤时必须对土壤母质有一个比较清晰的了解。什么叫做成土母质?地球上的岩石经过风吹雨淋、日晒冰冻,以及各种化学、生物作用,由坚硬的、大块的岩体变成疏松散碎的泥砂,就称为土壤母质,它是形成土壤的基础。要辩别母质类型,首先要对岩石、矿物有所认识。
Second, the identification of rocks, minerals and soil parent material is developed from soil parent material, the parent material on the soil composition, development level and fertility level, often have a decisive impact. In the soil census, the parent material factors are often divided soil, soil species, variants of the basis. Therefore, in the census of soil must have a clear understanding of soil parent material. What is made of soil Mother of the earth? The rocks on earth after the wind and rain, sun and ice, and a variety of chemical and biological effects, from hard, large rocks into loose loose sand, called soil parent material It is the foundation that forms the soil. To discriminate the type of parent material, we must first understand the rocks and minerals.
