对龙牙百合新品种白雪皇后(snow Queen)进行了物候期、植物学特征和植株生长规律等方面的研究。研究表明,白雪皇后越冬生长没有休眠表现,适宜促成栽培。有一至数朵白色花,花期8～10d。全年植株生长有一个缓慢生长期和快速生长期,4月是植株营养生长的最高峰。试验发现,鳞茎种球大小不仅对植株生长的高度、叶数有显著的影响,而且对新鳞茎产量、产出比以及气生鳞茎的产量都有明显的影响。打顶植株的新鳞茎、气生鳞茎的产量均大大高于开花植株。
The research on the phenophase, botanical characteristics and plant growth law of the new species of Aralia Lily for Queen Snow Queen was carried out. Studies have shown that snow queen no winter dormancy growth performance, suitable for promoting cultivation. One to several white flowers, flowering 8 ~ 10d. Plant growth throughout the year has a slow growth period and rapid growth period, April is the peak vegetative growth of plants. The results showed that bulb size not only had a significant effect on plant height and leaf number, but also had significant effects on bulb yield, yield ratio and bulb yield. The yield of new bulbs and aerial bulbs of topping plants were much higher than that of flowering plants.
