摘要
通过仪器分析方法,系统地研究了不同环境条件对硝磺草酮在土壤中的淋溶规律的影响。试验结果表明:不同浓度的硝磺草酮在不同降雨量、不同有机质含量以及添加不同助剂的情况下,在不同类型的土壤中的淋溶存在差异。随着硝磺草酮浓度增高,降雨量的增加,土壤淋溶深度加深;随着土壤中有机质含量的增加,土壤吸附能力增加,土壤检测浓度逐渐降低;不同助剂的添加,在不同类型土壤中,随着硝磺草酮淋溶深度的增加,土壤检测浓度逐渐下降。
Using instrument determination, effect of environmental conditions on leaching regulation of mesotri？one in the soil was systematically studied. The results showed that leaching of different concentration of mesotrionewere different under different rainfall, in different kinds of soil with different organic matter and different additives.As concentration of mesotrione and rainfall increased, it leached deeply in the soil. With the increase of organic mat？ter content in the soil, the absorbability of soil increased, the determined concentration gradually reduced. Differentadditives were added in different soil, with increase of concentration of mesotrione, the determined concentration insoil gradually reduced.
