摘　　要：为了探讨使它隆除草剂(Starane200)对长筒石蒜生长的影响,以盆栽长筒石蒜(Lycoris longituba)为研究材料,在叶期喷施不同浓度的使它隆,而后测定叶片净光合速率及收获鳞茎生物量。结果显示,喷施1次不同浓度的使它隆,各处理间叶片净光合速率及鳞茎生物量无显著性差异,但有枯叶期提前的现象,综合考虑,建议在使用中应尽量小心。In order to investigate the effect of herbicide Starane200 on the growth of Lycoris longitub, different dosages of Starane200 were sprayed on leaves of potted Lycoris longituba, and then net photosynthetic rate (Pn) was measured and fresh bulb biomass was harvested. The results showed that there was no significant difference in Pn and fresh bulb biomass, but Starane200 speeded up leaf abscission. All things balanced, carefulness should be taken in weeding practice.
