摘要:
采用高效液相色谱法，系统研究了不同降解菌及其多元混配在土壤中对氯嘧磺隆的降解作用。结果表明：真菌黑曲霉、青霉、F8和F31酿酒酵母在土壤中对氯嘧磺隆的降解速度存在显著差异，而且均能加快氯嘧磺隆的降解速度，其降解能力黑曲霉＞F31＞青霉＞F8。黑曲霉分别和青霉、F8、F31混合后，各处理间差异显著，并且随着黑曲霉比例的增加，对土壤中除草剂的降解能力明显增强，其中F31和黑曲霉混合后效果最佳，降解率可达86.43%。对降解菌进行三元混配后发现，在二元复合的基础上添加少量青霉可进一步提高降解能力。
Abstract:
In this paper, a high performance liquid chromatography method was established for determination of the degradation rates of chlorimuron-ethyl.The biodegradation of herbicide chlorimuron-ethyl in the soil by different strains was researched systematically.The results showed that the degradation rates of herbicide chlorimuron-ethyl by Aspergillus niger, Penicillium, F8 and F31 were significantly different in the soil.The herbicide chlorimuron-ethyl could bedegraded effectively by all these four strains.The degradation ability was Aspergillus niger＞F31＞ Penicillium＞F8.The degradation rates of herbicide chlorimuron-ethyl by Aspergillus niger respectively mixed with Penicillium, F8 amd F31 were significantly different With the increase of proportion of Aspergillus niger, herbicide degradation ability was significantly enhanced. The F31 and Aspergillus nige blend was the best combination and the degradation rate reached 86.43%. On the basis of binary mixture, addition of a small amount of Penicillium could further improve the ability of degradation.
