摘 要:稻区使用噻枯唑防治白叶枯病,毗邻稻田的非目标作物(蔬菜)区农田大气中含量可达ppb~ppm级水平,随气流飘移、扩散,沿水平向呈指数型分布.距用药区2m之内,各种蔬菜作物上的残留高达20~30ppm,2~10m内全部超标,30m处仍处于MRL值同一量级,稻田用药是构成蔬菜区的主要污染源之一.When saikuzuo was used in rice field to protect rice from rice bacterial leaf blight, the amount of saikuzuo in non-target crops of neighboring field ranged from ppb level to ppm level, with shift and diffusion of air, the amount of saikuzuo was distributed with logictic model. The amount of saikuzuo in vegetable crops was 20-30 ppm, where 2m aparting from tested field, and was beyond MRL where the distance was within 2-10 m, It was still the same level as MRL for 30 m distance. The main pollution source was the application of saikuzuo in rice field.
