摘　　要：为探求微量元素对提高忽地笑叶生长量和鳞茎产量的作用,以高浓度锌肥和硼肥在沙床上进行施肥试验,观测了叶生长量和鳞茎生物量的变化。结果表明:在栽培基质沙土中增施锌肥和硼肥未明显增加忽地笑的叶片数量、叶片长度及鳞茎生物量,说明石蒜属植物通常不需要施肥,补充微量元素的作用也不显著。Zinc and boron fertilizers were used as topdressing fertilizing to study the fertilizing effects on leaf growth and bulb biomass. Results showed that the fertilizing with zinc and boron couldn＇t increase the number and length of leaves, as well as the biomass in bulbs. It may further explain that plants of Lycoris generally do not need fertilization even the trace elements.
