摘要
为明确贵州喀斯特山区金刺梨种植基地土壤有效养分含量的丰缺现状,对乌当区和平坝县金刺梨种植基地土壤的有效锌、有效铁、有效铜、有效锰、有效硼、碱解氮、有效磷和有效钾含量进行测定,并分析有效养分含量之间以及其与土壤有机质含量和p H值的相关性。结果显示,乌当区金刺梨种植基地土壤有效锌、有效铁、有效铜、有效锰、有效硼、碱解氮、有效磷、有效钾含量分别处于高量、过量、过量、过量、缺乏、高量、缺乏、极缺水平,平坝县金刺梨种植基地土壤上述有效养分含量分别达到高量、高量、过量、高量、适量、过量、高量、缺乏水平,土壤p H值对两地土壤有效养分含量影响较大,土壤有机质含量与有效铜含量呈显著正相关,建议选择合适时机在乌当区补施硼肥、磷肥和钾肥,在平坝县补施钾肥。
In order to explore the soil available nutrients level in the Rosa sterilis planting bases located in Karst mountains of Guizhou province, the contents of available Zn, Fe, Cu, Mn, B, N, P and K in soil in Rosa sterilis planting bases in Wudang district and Pingba county were analyzed. The results showed that the contents of available Zn, Fe, Cu, Mn, B, N, P and K in soil were belong to rich, extremely rich, ex- tremely rich, extremely rich, lack, rich, lack, extremely lack level respectively in Wudang district, and rich, rich, extremely rich, rich, medium, extremely rich, rich, lack level respectively in Pingba county. Mo- reover, the influence of soil pH value on the contents of soil available nutrients was great, and organic mat- ter content was significantly positively related with soil available Cu content. Based on the experimental results and data analysis,it was suggested that more B fertilizer,P fertilizer and K fertilizer should be ap- plied in Wudang district,and more K fertilizer in Pingba county in the appropriate time.
