Abstract
①研究之土壤選自全省水稻田36代表剖面，包括五土類七亞類，27土型、76土樣。分析項目凡八，目的在暸解本省水稻田各型代表之粘土礦物及其相關理化性質，以為土壤分類及施肥改良之參考。結果以圖一至十，表一至十一分別說明之。
②全部代表土樣之粘土礦物，不論表底土均含有伊萊石，此外部分土樣尚有以至石或綠泥石為顯著，間具有高嶺石，至原始礦物則石英亦頌普遍，間具長石。
③以土壤亞類言，橄欖色水稻土，稻田黃棕壤之粕土礦物，均以至石及其混合層為其優勢成分，而以伊萊石為次，見表3C及表5b，屬肥力潛能較厚之土壤。
④稻田低地沖積土及稻田低地磐層土之粘土礦物以伊萊石及輊石為優勢成分，混合層或高嶺石為次，見表5a，屬於中度肥力之土壤。
⑤灰色水稻土及灰棕色水稻土以伊萊石為顯著成分，至石及高嶺石次之，混合層及綠泥石更次之，見表3a及表3b，其肥力潛能更次之；而稻田低地灰粘土之粘土礦物以伊萊石及綠泥石為其顯著成分，混合層次之，見表5b，屬肥力較瘠之土壤。
⑥自粕土礦物及其他主要理化性，建議本省水稻田代表土型之土壤新分類系統見表十，其高級分類及與美農部第七次土壤分類草案對照見表十一。
1. Soils of this study were selected from 36 representative soil profiles of the paddy field in Taiwan. It included 5 great groups, 7 sub-grops, 27 soil types, and 76 soil samples. Eight items of physic-chemical properties were analyzed. The purpose of this study was to understand the clay mineral and the related physico-chemical proper ties of the representative soil types for the reference of the soil classification and the improvement of fertilizer application. The results were shown in from fig. 1 to 10 and from table 1 to 11.
2. Illite were the most dominant clay minerals that present in all of the representative soil samples. There were some vermiculite or chloride present apparently in part of the soils and some kaolinite also occurred. Concerning the primary minerals, quartz was very common in these soils and some with feldspar.
