- 摘要:
- 近年来除草剂在土壤中持续积累，对后茬敏感作物造成严重药害，导致作物减产甚至绝产，氯嘧磺隆就是其中一种广谱、超高效和残留期较长的磺酰脲类除草剂。该试验通过氯嘧磺隆降解菌的筛选并作用于受氯嘧磺隆药害的萌芽水稻种子，利用测定筛选出的氯嘧磺隆降解菌对氯嘧碘隆的降解作用来研究其对氯嘧磺隆的降解作用效果。结果表明：所筛选的氯嘧磺隆降解菌对氯嘧磺隆有一定的降解作用。在同一菌不同浓度下，氯嘧磺隆5 μg·kg-1时降解效果最好。在同一氯嘧磺隆水平下，降解菌稀释倍数为100倍时降解效果最佳。
- Abstract:
- In recent years the herbicide is accumulated continually in the soil,bringing serious chemical damage to the stubble sensitive crop，which resulted in the reduction of crop yield，even non-production.The chlorimuron ethyl is one of broad-spectrum,highly effective and sulphur ureide class weed killers.Through screening of the chlorimuron ethyl degradable bactieria and using it to affect the paddy rice seeds which were damaged by weed killer,the degeneration effect of the bactieria on the chlorimuron was studied.The result showed that the degeneration effect was the best when the dosage of chlorimuron ethyl was 5 μg·kg-1,the best degradation effect was obtained when the bactieria was diluted 100 times at the same level of the chlorimuron ethyl dosage.
