贵州顶坛花椒树体与土壤营养分析

Tree and Soil Nutrition Analysis of Zanthoxylum planispinum var.dintanens in Guizhou Province

[目的]研究顶坛花椒基地土壤养分与树体营养状况的现状及关系。[方法]对贵州顶坛花椒生长过程中出现的树体衰退现象,进行土壤与植株叶片营养状况分析。[结果]贵州顶坛花椒土壤中有机质含量较为丰富,土壤氮、磷、钾含量均较高,硼、铜含量差异不明显,部分树势衰退的椒园锌含量偏低,个别树体长势差的叶片中硼含量较低。[结论]该研究为探明花椒树体早衰的原因并制定防控措施奠定基础。

[Objective] To study the status and relationship of soil and tree nutrition in Zanthoxylum planispinum var. dintanens base.[Method]The soil and plant leaf nutritional status of Zanthoxylum planispinum var. dintanens which the tree decline phenomenon appeared in the process of growth were investigated and determined.[Result]The soil organic matter content was relatively abundant, soil N, P, K content were at a higher level,differences of B and Cu content were not obvious in the whole garden. Zn content was lower which the tree decline appeared, and B content was low in individual tree .[Conclusion] The study provides the basis for exploring the causes of premature aging and developing prevention and control measures..
