(1)背景：大百合Cardiocrinium cordatum（Thunb.）牧原（Makino）为百合科（Liliaceae）多年生草本植物，分布于东亚地区.虽然花访客为这个植物种已经被很好地报道，他们的授粉的贡献仍然未知。(2)方法：对中国大陆游客的传粉贡献进行评价。在一个自然的凉爽的温带森林中的心形花。我们调查了访问频率，花粉粒数，每个身体表面，坐果，和种子的平均数量，每个水果后，每个访问物种的单次访问。结合这些实验结果，我们确定了该物种最重要的传粉者。(3)结果如下：对于研究中调查的种群，三种最重要的传粉者是熊蜂（熊蜂）（蜜蜂科），汗蜂（蜜蜂科），和橘子红食蚜蝇（Episyrphus balteatus）（食蚜蝇科）。此外，我们还发现访花蚁（Myrmica ruginodis Nylander（s.l.））（蚁科）很小。(4)结论：传粉者的贡献不同花游客。我们的研究结果强调了目前有关访花物种的信息不足，以评估授粉的贡献。
(1) Background: Cardiocrinum cordatum (Thunb.) Makino (Liliaceae) is a forest perennial herb distributed in East Asia. Although flower visitors for this plant species have been well reported, their contribution to pollination remains unknown. (2) Methods: We evaluated pollination contribution for visitors of C. cordatum flowers in a natural cool temperate forest. We investigated visiting frequency, the number of pollen grains per body surface, fruit set, and the mean number of seeds per fruit produced after a single visit of each visiting species. Combining the results of these experiments, we determined the most important pollinators of this species. (3) Results: For the population investigated in the study, the three most essential pollinators were the bumblebee (Bombus diversus tersatus) (Apidae), sweat bee (Halictidae sp.), and marmalade hoverfly (Episyrphus balteatus) (Syrphidae). Additionally, we found that the contribution of a flower-visiting ant species (Myrmica ruginodis Nylander (s.l.)) (Formicidae) is small. (4) Conclusions: Pollinator contributions differed among flower visitors. Our results underscore the insufficiency of current information about flower-visiting species to evaluate pollination contribution.
