| 摘 要： | 为研究不同处理土壤中苯磺隆、尿素、多效唑对土壤微生物种群数量的影响,试验采用正交设计,结果表明,在供试浓度下,苯磺隆对土壤微生物种群数量有一定的抑制作用。但从微生物数量反映了在不同多效唑浓度、氮素水平和时间上存在着一定的差异性。土壤微生物群落可作为评价苯磺隆除草剂残留污染土壤生态环境效应的敏感指数。外源氮素(尿素)的添加,改善了土壤的生态环境,使土壤微生物群落的数量有一定程度的增加,也表明氮素能缓解农药残留物对土壤微生物的毒害效应。

| Abstract: | Under the experimental concentration of HER、urea、tribenuron-methyl,the change of tribenuron-methyl microbial community structure could be resulted in soil.While soil microorganism was inhibited by tribenuron-methyl,the influence of tribenuron-methyl on soil microorganisms was different dependinf on soil types and incubation time.Soil microbial population,may be taken as a sensitive indicators for assessing the ecological effect of tribenuron-methyl.After nitrogen(urea) was added,the number of soil microorganisms increased,and the toxicity of tribenuron-methyl to soil actinomyces decreased. |
