摘要： 为了查明攀枝花烟区土壤微量元素变化趋势,对该烟区 170 份耕层土壤样品进行了检测,结合2009-2010年土壤相关数据结果进行分析。 结果表明,与5年前相比较,攀枝花烟区土壤有效锌含量平均降幅达13.5%,其中米易县土壤有效锌含量提高37.4%,盐边县与仁和区土壤有效锌分别降低15.6%和38.2%。全市土壤有效硼提高30%,按土壤有效硼分级,全市72.29%土壤有效硼缺乏,仁和、米易、盐边烟区分别有70.58%、61.23%和63.75%的土壤有效硼缺乏。市土壤水溶性氯含量降低29.02%,其中米易土壤水溶性氯提高27.04%,盐边和仁和则分别降低38.2%和33.8%。

Abstract: To make clear the changing trend of soil microelement in Panzhihua tobacco-growing area, 170 soil samples of top layer were detected and analyzed based on soil data from 2009 to 2010. The results showed that compared with five years ago, the average content of soil available Zn decreased by 13.5%, in which, that of Miyi County increased by 37.4%, that of Yanbian County and Renhe County reduced by 15.6% and 38.2%, respectively. Soil available B in Panzhihua increased by 30%, according to the classification of soil available B, 72.29% of the soil in Panzhihua was lack of available B, and the available B lacking area proportion in Renhe, Miyi and Yanbian tobacco-growing area was 70.58%, 61.23% and 63.75%, respectively. Soil water soluble Cl content decreased by 29.02% in Panzhihua tobacco- growing area, but that in Miyi Country increased by 27.04%, and that in Yanbian and Renhe decreased by 38.2% and 33.8%, respectively.
