摘　　要：以菲咯啉、浓硫酸、溴化钾、浓硝酸等为原料,合成了1,10-菲咯啉-5,6-二酮。其结构经熔点、红外光谱、元素分析进行了确证。采用琼脂混药法研究了1,10–菲咯啉–5,6–二酮对稗草和夏至草的除草活性。结果表明:1,10–菲咯啉–5,6–二酮在0.0625～1 mg/ml 5种试验浓度下,对夏至草根、茎的抑制率接近100%;对稗草的抑制效果则随浓度的升高有所增强,当浓度大于或等于0.25 mg/ml时,对稗草的抑制率达80%以上。1,10 - Phenanthroline - 5,6 - dione was synthesized with 1,10 - phenanthroline hydrate, concentrated sulfuric acid, potassium bromide, concentrated nitric acid and so on. Its structure was character- ized by MP, IR, and elemental analysis. Its herbicidal activity against Echinochloa arusgalli （L.） Beauv and Lagopsis supina was studied by the agar mix medicine method. The results showed that the inhibition effect of 1 ,10- phenanthroline-5,6 -dione on the root and stem of Lagopsis supina was nearly 100% at 0. 0625 1. 000 mg/ml, and its inhibition effect on Echinochloa arusgalli increased with the increase of its concentration, which was more than 80% when its concentration was larger than or equal to 0.25 mg/ml.
