The editor will explain the knowledge of butterfly orchid flowering period regulation in flowers. The editor will answer your questions in detail below.
【Seedling selection】Mature plants are more sensitive to low temperature treatment, so it is necessary to select strong-growing plants with 2 years or more of age (6-8 leaves) for low temperature flowering induction, and the number of flowers can reach more than 10.
【Flowering time】It takes 110-130 days for butterfly orchids to bloom after low temperature treatment. Based on this, annual production of butterfly orchids can be achieved by adjusting the flowering induction time. If flowers are needed for the National Day and Mid-Autumn Festival, low temperature treatment must be carried out from late May to late June. If flowers are needed for the Spring Festival, low temperature treatment is required from the end of August to the beginning of June. Generally, when the flower stem grows to 10-15cm, the low temperature treatment should be terminated, otherwise the flowering will be delayed.
【Flowering location】Usually, low temperature catalysis is carried out in a low temperature greenhouse. In places with conditions, it is possible to go to high mountains with an altitude of 700m-1000m, using the mountain climate to regulate temperature, saving flowering costs.
【Increase light intensity】By slightly burning the leaves of butterfly orchids, increasing the light intensity to 15000-30000lx can promote bud differentiation and increase the flowering rate.
【Flower stem support】When the flower stem reaches 10-15cm, it should be fixed with an iron branch to allow it to grow upwards, otherwise the flower stem will bend towards the light, affecting the grouping and shaping later on.
The above methods for regulating the flowering period of butterfly orchids are for reference only.
