原始语种摘要: Abstract(#br)The widespread use of neonicotinoids has increased the risk of non-point source pollution. Previous studies mainly focused on neonicotinoid transport by runoff on gentle slopes and ignored the role of sediment. Neonicotinoid migration due to erosion could be underestimated because a considerable amount of sediment migration is caused by erosion on steep slopes. Here, we focused on the transport of two typical neonicotinoids, imidacloprid (IMI) and clothianidin (CLO), via runoff and sediment in new citrus orchards on steep slopes. The total runoff from the bare land (BL), biological crust (BC) and Kummerowia striata (Thunb.) Schindl. (KS) plots was 77.73, 66.22 and 46.94 mm, respectively, and the corresponding total sediment was 162.47, 54.00 and 3.51 kg ha -1 , respectively....
