水耕人为土是在水耕条件下形成的具有人为诊断层的独特土壤类型。对采自福建省北部的13个水耕人为土典型剖面进行了土壤形成条件调查和土壤理化性状鉴定,明确了其发生学特性,并依据《中国土壤系统分类检索(第三版)》,鉴定了其诊断层和诊断特性,确定了研究土壤剖面在中国土壤系统分类中的归属。鉴定出的诊断层主要有水耕表层、水耕氧化还原层、漂白层、黏化层;诊断特性主要有人为滞水土壤水分状况、潜育特征、盐积现象、氧化还原特性。13个剖面可分别归属为弱盐潜育水耕人为土、普通潜育水耕人为土、漂白铁聚水耕人为土、普通铁聚水耕人为土、普通简育水耕人为土5个亚类。
Hydroponic man-made soil is a unique soil type with man-made diagnostic layers formed under hydroponic conditions. The investigation of soil formation conditions and identification of soil physical and chemical properties of 13 hydroprobletic soil profiles collected from the northern part of Fujian Province made it clear that their occurrence characteristics were well characterized and identified according to China Soil System Classification and Retrieval (Third Edition) Its diagnostic layer and diagnostic properties, to determine the study of soil profiles in the Chinese soil system classification. The diagnostic layers identified are mainly hydroponic surface layer, hydropodic redox layer, bleached layer and mucilage layer. The main diagnostic properties are soil water status, latent characteristics, salinization phenomenon and redox properties. Thirteen sections can be classified as weak salt saline aquaculture artificial soil, ordinary submarine hydroponic artificial soil, bleached iron polyhydrophobic artificial soil, ordinary iron hydroponic artificial soil, and ordinary simplified hydroponic artificial soil five sub-categories.
