摘要
本研究对吉林省主要土类土壤矿物进行了分析与鉴定,在全省采集了30个剖面、83个土样,对每个土样分离为4个粒级,分别测定了矿物类型及各种矿物的含量,又对每个土样进行了有机质,可溶盐,磷酸钙、氧化物的分析。粘土矿物并附有X射线衍射图谱和电子显微镜照片。本文主要叙述长白山采集的4个土类、9个土样所做的上述分析及其结果的分布规律。
In order to analyse and determine soil minerals of the main greatgroups of soil in Jilin province, 30 profiles and 83 soil samples was separated into four particle fractions. Types of minerals and contents of various minerals in each particle fraction were determined. Organic matter, soluble salts, CaCO3, and oxides in each sample were analysed.Clay minerals were tested with electron microscope and X-ray diffraction.Here reported only the results of analysis made on 9 samples of four great groups collected in Changbai Mountain and the distributive parterns of the substances analysed.
