湖北省丘岗、平原主要土壤的表面化学性质与粘粒的矿物、化学组成

SURFACE CHEMICAL PROPERTIES, CHEMICAL AND MINERAL COMPOSITION OF CLAY FOR MAIN SOILS DISTRIBUTED IN ALLUVIAL PLAIN AND HILLS MOUND IN HUBEI PROVINCE

就湖北省丘岗、平原有代表性的黄褐土、黄棕壤、红壤，潮土、灰潮土，水稻土中的淹育性水稻土、潴育性水稻土、潜育性水稻土等主要农业土壤类型，分析讨论了土壤的表面化学性质与其粘粒的矿物、化学组成的特点及其相互关系。

Yellow cinnamon soil, yellow brown soil and brown red soil derived from Q\-3 or Q\-2, grey fluvo aquic soil and fluvo aquic soil originated from alluvial deposit and paddy soil derived from them are main cultivated soils distributed in the areas of hilly mound with gentle slope and alluvial plain in Hubei Province. The surface chemical properties and chemical, mineral composition of clay fraction in them were presented. The differences of these for them were analyzed and discussed. All these materials will provide a basic scientific base for the classification, gradation, rational utilization and amelioration of these soils.\;
