摘要
对红河州7个植烟县市217份土壤样品的有效态中微量元素进行分析测定。结果表明,红河烟区土壤有效钙、镁、铁、锌、铜、锰、硫平均含量分别为1 535.91,301.1,31.77,2.01,2.34,44.84,30.31 mg/kg,含量较丰富,氯离子平均含量仅为7.37 mg/kg,含量偏低。不同pH环境下有效锌含量差异不大,其余元素变化较大;不同土壤类型及海拔高度下土壤有效钙含量差异大,其余元素变化不大。采用聚类分析可将红河烟区分成3类:Ⅰ类包括红河州西南部4个烟站,其特点是有效钙、镁、锌、铁含量较丰富,有效锰相对较低,硫含量高,低氯;II类包括红河州中北部15个烟站,其特点是有效钙、镁、锌含量低,有效铁、有效铜、有效锰含量高,低氯,有效硫偏低;III类包括红河州东北部10个烟站,其特点是有效钙、镁、锌含量极丰富,有效铁相对较低,锰、硫含量中等、低氯。
The trace elements contents in 217 soil samples from 7 tobacco-growing areas of Honghe were determined. The results showed that available Ca, Mg, Fe, Zn, Cu, Mn and S contents were very rich in most of the tobacco-growing areas of Honghe with the mean of 1 535.91, 301.1, 31.77, 2. O1, 2. 34, 44. 84 and 30. 31 mg/kg and C1 content was low with the mean of 7.37 mg/kg. Soil trace elements had discrepancy from different pH environments, varied widely except available Zn. There was not significantly different of soil trace elements in different altitude and soil types except a- vailable Ca. According to the cluster analysis results, the 29 tobacco-growing points of Honghe were divided into 3 groups ： group I included four points in the Southwest of Honghe with richer effective Ca, Mg, Zn and Fe, relatively lower effective Mn, high content of S and low content of C1; group II included 15 tobacco-growing points in the North Center with low contents of Ca, Mg, Zn and C1, high contents of Fe , Cu, Mn, and lower content of S ; Group III included 10 tobacco-growing points in the Northeast with an extremely rich Ca, Mg, Zn contents, relatively lower Fe content, middle Mg, S contents and low C1.
