阿特拉津在土柱中的淋溶规律研究
摘要
通过室内土柱淋溶试验
对阿特拉津在2种供试土壤中淋溶规律及其影响因子进行了研究。结果表明
淋溶速度由1.8ml/min增至4.4ml/min
阿特拉津的土壤残留量降低
淋出量分别增加10.8%(黑土)
8.2%(草甸黑土);同时
增加土壤有机质含量
适当降低淋溶液中H+离子浓度
均有利于抑制土壤中阿特拉津的迁移与流失。研究结论对农业生产的污染防治具有积极意义。
Abstract
Through the soil column eluviation experiment in laboratory
the eluviation law of Atrazine in two kinds of soil and its impact factors were studied.The results showed that:When the eluviation rate was increasing from 1.8 ml/min to 4.4 ml/min
the residues of Atrazine in soil decreased
and the leaching increased respectively 10.8%(black soil)
8.2%(meadow black soil);At the same time
it was beneficial for inhibiting the moving and outflow of Atrazine in the soil through increasing the content of soil organic m...
