Abstract


In accordance with the general requirements of the cooperative group of Chinese Soil Taxonomy grassroots classification issues , Chunhua Town , Jiangning County , Jiangsu Province , is selected as a typical sample area moist the Alfisols primary classification research . Expedition to study a sample area of terrain landforms , vegetation , parent material and hydrological and other soil-forming factors ; terrain geomorphology and mother quality and other factors of space change settings of multiple profiles , press the field survey of the technical specification conducted a cross-sectional morphology of observation describe and records, collected from the analysis of the sample of 213 bags , carton 51 boxes specimen . Tray specimens under the soil profile , the profile record tables and other information of 51 profiles comprehensive comparison and classified , summarized the 11 characteristics of soil : thin layer of loess a weak brown soil compaction loess layer the the glue spots loess layer , homogenous brown soil , the glue spots brown soil , hydroponics surface water plows underlying layer of hydroponic markings , hydroponics deposited layer and hydroponics mother soil . Each characteristic soil related project analysis , to determine the most important physical and chemical properties of Change . Selected control layer of the soil series segment , in accordance with the the differentiation characteristic time stability , productive , intuitive and integrated principle , the characteristics of the soil type , thickness and arranged as a soil series based indicators , divided forest Department , Songshan Village Department , large cove Department , three Mile shops Department , Department of Seven Mile Gang and Tang Village Department six soil series and summarized to determine the amplitude of the major physical and chemical properties of the soil series , and soil series description of . Typical pedon of each soil series of comprehensive physical and chemical analysis to determine the the plots weak surface , sticky layer soil development , the stick pan layer , of hydroponics surface and hydroponics redox layer 5 diagnosis layers ; and has a man-made soil moisture condition of the soil of stagnant water , moist soil moisture condition , hot soil temperature conditions and iron features four diagnostic features . Divided in accordance with the diagnostic horizons and diagnostic characteristics of each soil series higher taxon . In accordance with the conditions and mineralogical type of soil particle size , soil temperature , divided each soil series belongs Turkish . Finally , the soil series retrieval table .
