摘    要:目的:通过对种植黄连(简称植连)土壤营养条件进行研究,为黄连的科学施肥提供依据。方法:利用常规方法对重庆石柱主要植连土壤植连前后土壤养分进行测定。结果与结论:植连基础土壤呈强酸性,有机质和全量氮、钾含量较高,全磷含量极低;除有效氮含量较高外,其余11个营养元素含量低且变异大(锌、钼除外)。种植黄连4年后的土壤pH提高,有机质、有效大量元素、中量元素(硫除外)和微量元素锰、锌、硼含量提高,土壤有效铁、铜含量明显降低,各养分元素的变异系数大大降低,土壤肥力水平差异减小。

关 键 词:植连土壤  营养特性

Abstract:Objective: To study the changes of nutrient contents in Chinese goldthread soil before and after planting Coptis chinensis. method: The soil in Shizhu,Chongqing,was analyzed for nutrient contents. Result and Conclusion: The results indicated that the preplanted soil was strongly acidic and the levels of organic matter, total nitrogen and potassium were high. However, the content of total phosphorus was very low;so were the contents of other eleven nutrients. Variations of nutrients except zinc and molybdenum were large. After four years of planting C. chinensis, the soil pH was increased. Contents of organic matters, manganese, zinc and boron were increased, while the contents of iron and copper were decreased. In general, the variance coefficient of all nutrient elements and the difference of soil fertility were decreased.
Keywords:Chinese goldthread soil  nutrient character
