Abstract:

采用室内模拟试验方法,研究了噻虫胺在3种不同类型土壤中的吸附特性、移动特性及其影响因素.结果表明,噻虫胺在江西红壤、太湖水稻土与东北黑土中的吸附较好地符合Freundlich方程,Kd值分别为0.49、1.99和4.42,Kd值大小次序依次为江西红壤<太湖水稻土<东北黑土.影响噻虫胺土壤吸附性的主要因素为土壤有机质.薄层层析试验显示,当溶剂展开至12.0cm处,噻虫胺在江西红壤、太湖水稻土和东北黑土中最远移至10-12cm、8-10cm、4-6cm处.土柱试验表明噻虫胺在红壤淋出液中质量分数为56.04%,太湖水稻土和东北黑土中的噻虫胺最远已移至20.0-25.0cm和15.0-20.0cm处.影响噻虫胺在土壤中吸附性和移动性的主要因素为土壤有机质含量.噻虫胺存在对地下水污染的潜在风险性,特别是在红壤环境下使用噻虫胺应该引起足够重视.
