昭通植烟土壤中4种微量元素含量状况
Analysis and Evaluation for Contents of Four Microelements in Zhaotong Tobacco Growing Soils
摘要
Abstract
[Objective] The research aimed to investigate the nutrients in tobacco growing soils of Zhaotong. [ Method] 605 soil samples were collected and analyzed from 57 villages and towns of 8 tobacco growing counties in Zhaotong. The contents of four microelements Zn, Mn, Mo and Cl were analyzed. [ Result] The content of the available Zn, Mn, Mo and Cl was 2.479, 24.444, 0.289 and 11.783 mg/kg. The coefficient of the variation was 258.61% , 76.78% , 69. 70% and 92. 34% , respectively. The range of content respectively was 0. 35 - 91.75, 2. 60 - 127.75, trace - 1.30 and trace -97.29 mg/kg. The types of four microelements were divided into six groups according to hierarchical cluster analysis. [Conclusion] The research could provide the theoretical basis for rational distribution of flue-cured tobacco production and balanced fertilization measures in Zhaotong.关键词
