摘　　要：对6种化学除草剂防除胡麻田稗草的药效、安全性及其对胡麻产量、经济性状影响进行田间试验研究。结果表明:使用烯草酮216.00 g a.i./hm^2、精喹禾灵45.00 g a.i./hm^2、炔草酯78.75 g a.i./hm^2、精吡氟禾草灵157.50 g a.i./hm^2可以安全有效的防除胡麻田稗草,株防效97.73%~98.14%,鲜重防效99.64%~99.82%,提高产量18.84%~51.82%。The efficiency and security of effect of six kinds of herbicides on control of Eehinochloa cmsgMli （L.） Beauv. and on the yield and economic traits of flax were studied. The result showed that clethodim of EC 216.00 g a.i./hm2, quizalo- fop-p-ethyl of EC 45.00 g a.i./hm2, clodinafop-propargyl of WP 78.75 g a.i./hm2, fluazifop-p-butyl of EC 157.50 g a.i./hm2 had safe efficiency. The preventing effect reached 97.73% to 98.14% for each plant and 99.64% to 99.82% for raw weight, and the yield increased by 18.84% to 51.82%.
