采用室内吸附试验方法及室内模拟土柱方法,研究了腐植酸对除草剂胺苯磺隆的吸附及其对胺苯磺隆在红壤中淋溶迁移的影响。结果表明,腐植酸对胺苯磺隆的吸附能力很强
The effects of humic acid on the adsorption of herbicides, ethamsulfuron-methyl and the leaching of metsulfuron-methyl in leaching red soils were studied by using indoor adsorption method and simulated soil column method. The results showed that humic acid has strong adsorption capacity of triasulfuron
