摘　　要：田间杂草严重影响百合种球产量和品质,人工除草费用高,且效果不好。为了降低种球繁育成本,有效清除百合生长期田间杂草,以东方百合西伯利亚(Siberia)为试验材料,开展化学除草药效试验并评价了不同除草剂对百合的安全性,以期筛选出防效好、安全性高的药剂。结果表明:三木马(56%灭草松+5%精喹禾灵+乙烯基三甲氧基硅烷)对荠菜、藜、稗草、狗尾草、马唐防除效果较好,低浓度处理种球平均重量与对照差异不显著。高效氟吡甲禾灵对稗草、狗尾草、马唐三种禾本科草防除效果好,对百合安全性高。Field weeds seriously affect the yield and quality of lily bulbs.In view of this situation that artificial weeding needs a higher cost and unsatisfactory results,a comprehensive study on weeding method by chemical control was conducted.In order to reduce the bulb production costs,and effectively eliminate weeds in lily growing period,the chemical weeding efficacy test was carried out with‘Siberia’as the experimental material,and the safety of different herbicides on lily was evaluated,so as to screen out the pesticides with good control effect and high safety.The results showed that the three Trojan horses(56%fenazone 5%quizalofop ethyl vinyltrimethoxysilane)benefit to weed contro on Shepherd's purse,Chenopodium album,Barnyard grass,Green bristlegrass and Crabgrass.There was no significant difference in average weight of seed balls between low concentration treatment and control.Flupirofop-p-ethyl exhibit good control effect on Barnyardgrass,Green bristlegrass and Crabgrass,and had high safety to Lily.
