| 摘要: |
| 为了解天贵卷瓣兰Bulbophyllum tianguii的传粉机制，对广西雅长兰科植物国家自然保护区内天贵卷瓣兰的伴生植物种类、传粉生物学、形态特征、物候等情况进行调查研究。天贵卷瓣兰的伴生植物主要有细叶云南松Pinus yunnanensis、化香树Platycarya strobilacea、小叶枇杷Eriobotrya seguinii （Levl.） Card.ex Guillaumin、米念芭Tirpitzia ovoidea、三对节Clerodendrum serratum等。天贵卷瓣兰的花期为2月中旬至3月下旬，盛花期在3月中旬，单株单花花期在一周左右。天贵卷瓣兰在自然状态下，自交或异交授粉结实率都很低，试验通过碾碎花粉的形式进行授粉，可显著提高天贵卷瓣兰的结实率，达到100%。 |

| Abstract: |
| In order to research the pollination mechanism of Bulbophyllum tianguii,the associated plants species,biological,morphological characteristics of pollination and phenological in Guangxi Yachang Orchid National Nature Reserve were investigated.The accompanying plants are Pinus yunnanensis,Platycarya strobilacea,Eriobotrya seguinii,Tirpitzia ovoidea,Clerodendrum serratum,et al.The flowering period of Bulbophyllum tianguii is from mid-February to late March,the blooming period is in mid-March,and the flowering period of single plant is about one week.In the natural state，the seed setting rate of self- or cross-pollination of Bulbophyllum tianguii is very low.In the experiment,pollination was carried out by crushing pollen,which could significantly improve the seed setting rate of Bulbophyllum tianguii,reaching 100%. |
