长白山区垂花百合园艺栽培技术

垂花百合(Lilium cernuum)野生资源分布稀疏、数量较少,是园林杂交育种的重要野生种源,具有较高的经济价值.对垂花百合的形态学特征、地理分布、生态学习性及长白山区垂花百合的物候特征进行描述,并重点对其繁育技术、田间管理、病虫害防治等进行研究.结果发现:人工栽培的垂花百合在花、叶、鳞茎的生长上都明显优于野生自然生长的垂花百合;引种栽培后病害较多,易倒伏;第1年遮阴栽培是关键,需遮阴50%;有性繁殖时,种子需暖温处理,发芽率可达70%以上.无性繁殖生长较快.

Horticultural Technology of Lilium cernuum in Changbai Mountain

Lilium cernuum is an important cross-breeding wild provenance, it is sparse and scarce with high economic value. The morphological feature,geographical distribution,ecological habit and phenological character of Lilium cernuum were described, focused on its breeding technology, field management and pest control. The results show that cultivated Lilium cernuum is much better than wild species in the growth of its flowers,leaves and bulbs. After introduction and cultivation,Lilium cernuum will be prone to disease and lodging. It is critical to be cultivated under shade condition in the first year,50% shade required. In sexual reproduction,its seeds need warm processing and the germination rate can be more than 70%,while asexual reproduction is faster.
