摘　　要：试验利用对氟磺胺草醚敏感的玉米、向日葵、高粱为指示作物,利用土培法研究了不同条件下,氟磺胺草醚不同浓度对作物的抑制作用,并建立了氟磺胺草醚玉米生物测定方法——玉米株高法。试验结果表明,最佳生物测定条件为在27℃条件下,培养120 h。研究结果对土壤中氟磺胺草醚的快速测定和轮作换茬具有重要意义。The inhibition action of different dosages of formsafen on plants was studied with the indicator plants of corn,sorghum,sunflower in different conditions,and the bioassay methods of formsafen in soil-corn plant height method was established.The results showed that the inhibition rate of corn plant height had the significant linear relationship with dosages of solutions in the optimum condition of lighting training for 120 h,27 ℃.It provided a instruction for the fast determination of formsafen and crop rotation and crop planting structure adjustment.
