七种观赏贝母在北京地区的引种栽培

Introduction and Cultivation of Seven Ornamental Fritillaria Species in Beijing

为促进观赏贝母的推广应用,丰富北京乃至华北地区春季景观,本试验对从荷兰引进的7种观赏贝母进行了引种适应性研究,评价指标包括物候期、生长指标、形态特征、开花特性和种球性状等。结果表明:7种观赏贝母在北京地区长势差别较大,F.camschatcensis、F.pallidiflora和F.bucharica长势良好,开花率高,可以直接在北京推广应用;F.acmopetala、F.sewerzowii和F.elwesii虽然出苗率高,但开花率不高,可能对当地的气候条件还不适应,建议进一步观察。F.davisii没有开花,建议进行温室栽培种植。

In order to promote the popularization and application of ornamental Fritillariaand enrich the spring landscape of Beijing and even North China,the introduction adaptability of seven ornamental Fritillariaspecies introduced from Holland was studied in this experiment.The evaluation indexes included phenological period,growth index,morphological characteristics,flowering characteristics and bulb traits.The results showed that,the growth of 7 species of ornamental Fritillaria varied greatly in Beijing.F.camschatcensis,F.pallidiflora and F.bucharicagrew well and had high flowering rate,which could be directly popularized and applied in Beijing;although F.acmopetala,F.sewerzowii and F.elwesii had high seedling emergence rate,their flowering rate was not high,which might not be adapted to the local climate conditions,so further observation was suggested.F.davisii did not bloom,so it is recommended to plant in greenhouse.
