摘要
对咪唑啉酮类除草剂灭草烟在8种土壤的吸附、脱附进行了研究,对振摇时间、温度、土壤pH值的影响作了探讨,并对吸附、脱附常数与土壤的理化性质的相关性进行了分析。结果表明,灭草烟在土壤中吸附常数和土壤〔H+〕(OM%)呈正相关。
The adsorption and desorption of imazapyr on eight soils of various physical and chemical properties were studied. The correlation of Freundlich adsorption and desorption constant, Kaf and Kdf, with physical and chemical properties of soils were also studied. The results show that Kaf increases with the increase of 〔H+〕O.M.% of soils;and the desorption rate increases with the decrease of O.M.% of soils.
