摘要:: 以贵州地产山银花不同种植年限土壤为研究对象，通过野外调查与室内分析相结合的方法，对比研究了山银花不同种植年限下土壤团聚体、土壤肥力和土壤重金属的污染程度。结果表明：土壤中5~1 mm和1~0.25 mm团聚体占的比例最高，粒径大于1.00 mm水稳性土壤团聚体的总量都是根区大于非根区，总体上土壤结构性好；碱解N、有效P、速效K，有机质等土壤肥力指标等级大都为Ⅰ级或者Ⅱ级，大部分处于丰富水平，11~20 a的根区土壤养分丰富比例最高；参照贵州省土壤背景，重金属As随着种植年限增加污染程度有增加趋势，总体土壤尚清洁。研究可筛选出高产优质山银花的最佳种植年限，为贵州生产高产优质山银花的栽培管理及施肥技术奠定基础。

Abstract:: The soils of Flos Lonicerae Confusae under different cultivating years were selected as the samples in Guizhou. The soil aggregates, the soil fertility and the pollution degree of soil heavy metals of Flos Lonicerae Confusae under different cultivating years were comparatively investigated. The results showed that the proportions of 5~1 mm and 1~0.25 mm aggregates in soils were the highest, the total amount of water stable soil aggregates greater than 1.00 mm in root zone were higher than that in the non root zone, on the whole the soil structure was better. The soil alkali solution N, available P, available K, organic matter were grade I or Ⅱ, most of which were at the rich levles, the proportion of nutrient richness in root soil under the 11~20 years was the highest. According to the reference background of Guizhou Province, the pollution level of As increased with the duration of planting years, but the soil was generally slightly clean. The best planting duration for high quality Flos Lonicerae Confusae in this study was selected, and the foundation of the cultivation management and fertilization technology for high quality Flos Lonicerae Confusae in Guizhou was put forward.
