In the process of promoting flowering, do not put potted plants in a place with artificial light at night, otherwise extra light may affect flower bud differentiation and later flowering. For example, if you make it bloom ahead of the National Day, you can shade it at the end of July and early August, cover it with a black cloth sheet from 4: 00 p.m. to 8: 00 a.m. every day, and give birth to buds at the top of each stem node in late September. Shaded until the end of September, the bud can open from the beginning of October.
Crab claw orchid is sensitive to temperature and grows well in the range of 16 to 28 ℃. In the process of controlling the flowering period, the ambient temperature should not be lower than 5 ℃, otherwise it is easy to freeze the plants. In general, when the air temperature is lower than 13 ℃, the flowers can no longer develop normally under the influence of photoperiod, while when the temperature is higher than 15 ℃, the flower bud differentiation can only be carried out under the condition of short-day light. When the temperature is higher than 21 ℃, there is no flower bud differentiation in both long-day and short-day conditions.
The natural florescence of crab claw orchid can be delayed to March. For this reason, if the plant that has finished the bud is nearly open, the temperature can be controlled above 5 ℃, and the opening of the bud can be delayed by low temperature.
