吉林省主要耕作土壤胶散复合体的组成特征

Study on the Composition of Organic-Mineral Complex of Major Cultivated Soil from Jilin Province

以吉林省 3种主要的耕作土壤为供试样品 ,采用傅积平等改进的丘林胶散分组法分离复合体。试验结果表明 :胶散复合体的总量以黑钙土最低 ,平均为 134g/kg ;白浆土与黑土相近 ,分别为 434g/kg和435 g/kg。粘粒含量是影响复合体含量的重要因素 ,复合体的含量与土壤性质间有明显的相关关系。土壤有机碳在各组复合体的分布量 。

The composition of organo mineral complex of three kinds of cultivated soil collected from Jinlin Province was examined. The organic mineral complex of soil samples was grouped using colloid grouping method described by Qiulin and modified by Fujiping. Results showed that the total content of organic mineral complex was the lowest in Chemozem, averaging 134?g/kg and was similar in Albic soil and black soil, with averages of 434?g/kg and 435 g/kg, respectively. The clay content is an important factor affecting complex content. Soil property was correlated with the complex content The distribution of organic C in a complex mainly depends on relative content of the complex in the soil
