主　　题：Groundwater Soil amendments Wheat crop Sulfosulfuron Leaching 

摘      要：A field study with wheat crop was undertaken to examine the efficacy of two soil amendments,cereal straw and fresh cow dung slurry,in reducing leaching of sulfosulfuron to groundwater and its residue load in *** herbicide was extracted by the QuEChER’S method and quantified through high performance liquid *** amendments had no effect on the general properties of *** cereal straw and fresh cow dung reduced leaching of sulfosulfuron into groundwater but cereal straw was more effective,probably because its addition decreases soil pH,thereby causing faster hydrolysis of the *** harvest time,residues of the herbicide in grains,straw and soil were below recommended maximum residue limits(0.1mg kg-1)with both ***,both the amendments can be recommended for wheat cropping systems to control sulfosulfuron leaching to groundwater.
