在温室栽培尤其是庭院栽培中,环境有时不能完全满足蝴蝶兰最适宜的生长要求,因而导致其生理发生变化,出现让人难以理解的生长异常现象,如顶端抽生花梗、花色变浅、花朵变小、株型变异、叶片轮生等。我们根据多年来栽培蝴蝶兰的经验,就这些异常现象谈谈自己的看法。一、花梗芽异常花芽一般在从上往下第3～4片叶的叶腋处抽生花梗,花梗节芽都带有苞片及潜伏芽。但在不适宜的环境下,当其自身营养积累较少,当年新生叶片也较少时,便很可能在兰株顶芽处萌发花芽。此时如遇到较低日温,则花芽抽出花梗,继而开花;如遇较高日温,便很可能出现苞片长成叶片或潜伏
In greenhouse cultivation, especially in garden cultivation, the environment sometimes can not completely meet the most suitable growth requirements of the Phalaenopsis, resulting in physiological changes that cause unimaginable growth anomalies such as top pumping pedicels, shallow floral colors, Smaller, plant type variation, leaf rotation and so on. Based on our years of experience in cultivating Phalaenopsis, we share our own views on these anomalies. First, abnormal flower buds buds generally in the leaves from the top 3 to 4 leaf axils pumping pedicel, pedicel buds are with bracts and latent buds. However, under unfavorable conditions, when their own nutrition accumulation is small and new leaves are fewer in that year, buds are likely to germinate at the top of the blue plant. At this time in case of lower day temperature, the flower buds out of the peduncle, and then flowering; in case of high temperature, it is likely to bracts grow into leaves or latent
