杏黄兜兰和硬叶兜兰在北京的催花比较试验

Flower forcing comparison trials of Paphiopedilum armeniacum and Paphiopedilum micranthum in Beijing

为确保2011年春节兰展期间能够将从贵州引种的杏黄兜兰和硬叶兜兰及时展出,在春节前对这两种兜兰进行引种催花比较试验。结果表明:(1)杏黄兜兰更适宜换基质栽培,硬叶兜兰是否换基质对其花芽率的影响不大。(2)硬叶兜兰更适宜在11月引种并做低温处理,如果在9月引种也适宜做低温处理;杏黄兜兰对引种的月份要求不高,两个月份引种都不适宜做低温处理。(3)高温温室的催花时间应在春节布展前2～3个月较合适,大约在11月。

In order to ensure that Paphiopedilum armeniacum and Paphiopedilum micranthum can be displayed timely to the visitors during the period of 2011 Spring Festival orchids show, we conduct the flower forcing comparison trials with the two kinds of Paphiopedilum which were introduced from Guizhou province before Spring Festival. Through the experiment of introduction time （September, November） , low temperature treatment and matrix replacing, more accurate data of the most suitable condition to flower forcing of two species were obtained. The results indicated that： （1） Paphiopedilum armeniacum is more suitable for changing matrix culti- vation, and only little influence of whether or not changing matrix on flower bud rate of Paphiopedilum micranthum. （2） Introducing Paphiopedilum micranthum is more suitable in November with low temperature treatment. If introducing in September, it is better with low temperature treatment too. There was no difference between the introductions of Paphiopedilum armeniacum in September and that in November, and Paphiopedilum ormeniacum is not suitable for low temperature treatment in these two months. （3） The appropriate flower forcing time is about November, i.e. 2-3 months early before spring festival orchid show.
