基于野外调查信息的河南省灵宝市和襄城县典型烟田的土系建立

Preliminary Establishment of Soil Series of Typical Tobacco Fields in Xiangcheng and Lingbao of Henan Province Based on Information of Field Survey

以河南省豫中平原区的襄城县和豫西黄土高原区的灵宝市为研究区域,通过对灵宝市5个和襄城县10个典型优质烟田的土壤调查,尝试建立相应的土系。结果表明,灵宝市烟田土壤主要是发育于黄土母质,亚类上均属于普通简育干润雏形土,为同一土族,依据土体中新生体如砂姜、铁锰结核、碳酸钙假菌丝体等的有无可暂划为4个土系。襄城县10个烟田土壤主要发育于黄土冲积物和古黄土性河湖相沉积物上,亚类分别归属于普通钙质干润淋溶土、石灰底绣干润雏形土、变性砂姜潮湿雏形土、石灰淡色潮湿雏形土和普通淡色潮湿雏形土,分属6个土族,同一土族下不同的烟田土壤,主要依据土体色调的差异可暂划为8个土系。

This paper took Xiangcheng and Lingbao as two typical tobacco-planting regions of Henan Province,selected 5 and 10 typical tobacco fields respectively from Lingbao and Xiangcheng which could grow the tobacco leaves of the highest-quality and tried to establish preliminarily the relevant soil series mainly ba（s）ed on soil information obtained in field survey.The results showed that the 5 typical tobacco field soils in Lingbao were derived from loess parental material,belonged to Typic Hapli-Ustic Cambosols in subgroup of the same family and could be categorized into 4 series according to the contents of new growths such as Shajiang,iron-manganese concretion and CaCO3 pseudomycelium,while the 10 typical tobacco field soils in Xiangcheng were derived from alluvial deposits and river-lake sediments of loess parental material,belonged to Typic Carbonati-Ustic Argosols,Calcaric Endorusti-Ustic Cambosols,Vertic Shajiang-Aquic Cambosls,Calcaric Ochri-Aquic Cambosols and Typic Ochri-Aquic Cambosols,and could be categorized into 8 series according to the differences in color hues within the same family.
