Abstract:

氯酸盐是生产工业漂白剂二氧化氯的重要原料,也常被用作除草剂和土壤消毒剂,龙眼园施用氯酸钾不仅对土壤生态系统产生影响,施用不当还会造成植物损害乃至死亡。为了进一步明确氯酸根(ClO-3)在土壤中的迁移转化途径,在实验室条件下研究了氯酸盐在不同类型龙眼园土壤中的降解和吸附特性,探讨了可能对吸附造成影响的各种因素。结果表明,土壤对氯酸根有较弱的吸附能力,土壤中的微生物可以降解氯酸根,不同类型的土壤对氯酸根的吸附有显著性的差异,土壤对氯酸根的吸附符合Langmuir吸附等温方程。可参照不同土壤性质了解其降解和吸附氯酸盐的特性,确定龙眼催花的适宜施药剂量和采取相应土壤管理技术措施加快其降解,以减少氯酸盐的负作用。
