摘要
通过对河套地区土壤中矿物组成的分析研究,土壤中矿物组成中砂质成分主要为石英、长石、方解石,黏土矿物组合主要为伊利石、绿泥石和高岭石,此外还有角闪石等少量矿物成分。在砂土、粉砂土中石英、长石含量较高,在黏土质为主的土壤中黏土矿物含量增加。黏土矿物与石英以及长石呈负相关关系,与大多数元素呈明显正相关关系,黏土矿物对各元素具有明显吸附性;石英、长石与各元素含量呈负相关关系,说明其对元素不具有吸附性。
An analysis of the composition of soil minerals in the Hetao area shows that the main arenaceous components are quartze, feldspar and calcite, whereas the clay minerals are composed of illite, chlorite and kaolinite. The contents of various minerals are dif- ferent from each other. Quartz and feldspar are relatively high in sandy soils, while clay minerals are comparatively high in clay soils.
