| 摘 要： | 以14C-甲磺隆为例,通过投加优选菌株青霉(Penicillium sp.)和发酵有机肥,研究了污染土壤中甲磺隆除草剂的生物修复。结果显示,加入优选菌株Penicillium sp.或有机肥对甲磺隆污染土壤进行生物修复是可行的,Penicillium sp.或有机肥的引入,显著提高了土壤中甲磺隆残留物的降解速率,并大大减少了土壤中结合态甲磺隆残留物的形成,甲磺隆的降解半衰期由162.3 d降至42.5~51.6 d,56 d时其结合残留率仅为1.1%~4.6%,而对照土壤中结合残留率仍达到35.6%。

| Abstract: | The results showed that it was effective for bioremediation of metsulfuron-methyl to add Penicillium sp.or compost to contaminated soil. The degradation rate of metsulfuron-methyl was significantly improved after addition of selected Penicillium sp.or compost to soil, and the half-lives were sharply decreased from 162.3 days to 42.5~51.6 days. At 56 days after treatment, the bound residues of metsulfuron-methyl were only 1.1%~4.6% in Penicillium sp.or compost treated soils, but were 35.6% in control sample. |
