摘　　要：[目的]明确300 g/L呋喃磺草酮·氟酮磺草胺SC在不同使用剂量的情况下,防除移栽稻田杂草效果、杀草谱、安全性及施用技术等项指标。[方法]采用毒土法施药、定期调查的方法进行田间药效试验。[结果]呋喃磺草酮·氟酮磺草胺杀草谱主要包括莎草科杂草、阔叶杂草和禾本科杂草。施用时间为水稻移栽后7~10 d。剂量为90~108 g a.i./hm^2,施药后30 d对稗草、阔叶杂草、莎草科杂草综合防效达76.3%~97.6%。[结论]正常使用量对水稻生长安全,与人工除草相比,产量差异不显著。[Aims] This study aims to clarify the criterion of controlling weed spectrum, safety and application technology of terfuryltrione-triafamone 300 g/L SC at different doses in rice field. [Methods] This experiment was carried out by means of poisoned soil. [Results] The results showed the suitable application period was 7-10 day after rice transplanting, and the dose was 90-108 g a.i./ha, its comprehensive control effect reached 76.3-97.6% after 30 d after spraying, and controlled weeds included barnyard grass, broad-leaved and sedge weed. [Conclusions] It was safe on rice growth in normal dose, compared with artificial weeding, showing little difference in yield.
