| 摘 要： | 目的]为查清昭通市植烟土壤养分丰缺状况。方法]采集昭通市8个产烟县区57个乡镇605个植烟耕层土壤,对Zn、Mn、Mo、Cl 4种微量元素进行化验分析。结果]全市植烟土壤速效锌含量平均2.479 mg/kg,变异系数258.61%,变幅为0.35～91.75 mg/kg;速效锰含量平均24.444 mg/kg,变异系数76.78%,变幅为2.6～127.75 mg/kg;速效钼含量平均0.289 mg/kg,变异系数69.70%,变幅为痕量～1.30 mg/kg;土壤水溶性Cl-含量平均11.783 mg/kg,变异系数92.34%,变幅为痕量～97.29 mg/kg。经系统聚类分析,57个乡镇植烟土壤Zn、Mn、Mo、Cl微量元素类型可分为6类。结论]该研究可为昭通烤烟生产的合理布局和平衡施肥措施的制定提供理论依据。

| 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. |
