采用野外调查采样和室内分析测定的方法,研究了湖南省丘岗地区7种类型水稻土的肥力状况,并选取土壤有机质、全N、全P、全K、碱解N、有效P、速效K、缓效K、有效Si、有效Zn含量和土壤pH共11项肥力指标,采用Fuzzy综合评判法,对湖南水稻土的肥力质量进行综合评价.结果表明,供试水稻土土壤偏酸性,有机质含量中等偏上,全K、碱解N含量较高,全N、全P含量一般,有效P、速效K、有效Si和有效Zn含量较低,有效S含量较丰富.供试水稻土土壤肥力质量高低不等:祁阳的灰泥田土壤肥力质量水平较高,达二级;宁乡的红黄泥和河沙泥、祁东的紫砂泥、醴陵的麻沙泥和湘潭的紫泥田水稻土壤肥力质量水平中等,为三级;株洲的黄泥...

The fertility status of seven main kinds of paddy soils which was sampled from hill-mound areas in Hunan was investigated in laboratory analysis. Eleven indices were selected as assessment parameters, including soil pH, organic matter, total N, total P and total K, available N, available P, available Zn and available Si, readily available K and slowly available K. The method of fuzzy comprehensive assessment was used to evaluate fertility quality of these paddy soils comprehensively. The results showed that the soils＇ pH is nearly acidic, the ...
