基于野外调查信息的山东省临朐县典型烟田土壤系统分类

Soil Taxonomy of Typical Tobacco Fields in Linqu County of Shandong Province

以山东省临朐县为研究区域,通过其典型优质烟田的野外土壤调查信息尝试建立相应的土系。结果表明:临朐县8个植烟片区9个典型优质烟田,主要为分布在高丘坡上的旱地,可归为淋溶土、雏形土和新成土;在系统分类上可划分为3个土纲、3个亚纲、5个土类、6个亚类、6个土族和8个土系;不同的土系在植烟优劣方面存在一定差异,属于淋溶土的土系有效土层深厚,但有黏化层可能妨碍根系下扎;属于雏形土和新成土的土系颗粒较粗而通透性好,养分含量较低易调控,但有效土层偏薄。

This paper took Linqu County of Shandong Province as the study region, selected 9 typical tobacco fields in different locations which could grow the tobacco leaves of the highest-quality and tried to establish preliminarily the relevant soil series based on soil information obtained in field survey. The results showed that the 9 typical tobacco field soils in 8 villages mainly were distributed at the slopes of high-hills, they could be classified into 3 orders, 3 suborders, 5 groups, 6 subgroups, 6 families and 8 series. There were differences between these 8 soil series in the suitability of tobacco growth, the series of Argosols usually had deep effective soil layers but claying horizons while the series of Cambosols and Primosols usually had good permeability and easy-control of soil nutrients but shallow effective soil layers.
