摘要

利用自行研制的原状土淋溶柱

研究了多菌灵在蔬菜地酸化黑土中的迁移规律

并通过调控土壤pH值和有机质含量

探讨了抑制多菌灵在黑土中迁移的技术措施。结果表明

添加消石灰

土壤值由5.1上升至6.2

多菌灵淋出量峰值较对照延迟出现

总淋出量较对照处理减少了31.3%;当土壤有机质含量由21.2 g/kg提升至30.7 g/kg时

多菌灵的总淋出量减少了23.7%;当同时添加消石灰和秸秆后

土壤中多菌灵的淋出峰值出现延迟

总淋出量较对照处理减少了46.0%

效果优于消石灰或秸秆单施处理

但混施处理的效果略低于二者单施处理之和。

Abstract

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.
