Using the independently made undisturbed soil column, the authors analyzed the migration rule of carbendazim as added in vegetable land with acidified black soil, and studied the inhibiting measures by regulating soil pH value and organic matter contents. The results showed that:(1) Soil pH value increased from 5.1 to 6.2, carbendazim leaching amount peak was delayed, and the total amount of leaching decreased by 31.3% compared to the control after application the hydrate lime.(2) When soil organic matter content was increased from 21.2 g/kg to 30.7 g/kg, the total amount of carbendazim adsorbed by soils decreased by 23.7%.(3) When addition of the hydrated lime and straw in soil at the same time, carbendazim leaching peaks were delayed too, and the total amount of leaching was 46.0% lower than that of the control. The effect of mixed application of the hydrated lime and straw on leaching delay was better than that of single application of hydrated lime or straw, but it was slightly lower than the sum of the hydrated lime and straw.
