摘  要：
通过对陕西洛南、旬阳、陇县3个典型植烟区剖面及耕层土壤理化指标的测定,采用主成分分析法,对3个植烟区土壤理化特性和肥力进行研究。结果表明:3地土壤体积质量和紧实度均偏高,属壤质粘土,pH偏高(洛南适宜除外);有机质含量偏低,氮含量偏低(洛南适宜除外),磷含量缺乏,钾含量较丰富。洛南土壤肥力指数最高,属1级;旬阳次之,属2级;陇县较小,属3级。3个植烟区可通过土壤改良剂及增施有机肥和平衡施肥等措施,促进烤烟生长发育及产质量提高。

摘  要：
The physical and chemical properties and fertility of three typical tobacco growing soil in Shaanxi Province was studied by measurement of the physical and chemical indexes of soil profile and cultivated soil using principal component analysis method.The results showed that the tested soils belonged to loamy clay with the properties of high bulk density and compaction.relative high pH values(except for optimal level in Luonan),low organic content,relative low nitrogen(N) content(except for optimal level in Luonan),rather low phosphorus(P) content,and relative affluent potassium(K) content.Furthermore,the fertility was affiliated as first,second and third grade in Luonan,Xunyang,and Longxian,respectively.Based on the above results,we suggested that soil amendment agent,organic fertilizer and balanced chemical fertilizer should be applied in the three tobacco-growing areas to improve growth and development,yield and quality of flue-cured tobacco.
