摘　　要：进行了8种除草剂对红麻幼芽和幼根生长影响的室内生物测定。结果表明,氯氟吡氧乙酸对红麻幼芽和幼根的抑制作用十分强烈,抑制率分别为80.63%、54.66%。苯达松、异丙隆和甲咪唑烟酸对红麻幼根和幼芽的抑制率均小于18%。The effects of 8 hebicides on shoot and root growth of Hibiscus cannabnus seedling were investigated by laborato- ry bioassay. The results showed that fluroxypyr presented quite inhibit effects on shoot and root growth of H. cannabinus seedling with the inhibition rate of 80.63% and 54. 66% respectively. Bentazone, isoproturon and imazapic presrnted little inhibit effects on shoot and root growth of H. cannabinus seedling with a inhibition rate less than 18%.
