The flowering period of Phalaenopsis is usually around the Spring Festival, and the viewing period can be as long as 2-3 months. The night temperature should be controlled between 13 ℃ and 16 ℃, but not lower than 13 ℃.
2. The flowering period of different Phalaenopsis varieties was as follows
(1) Phalaenopsis variegata, also known as Phalaenopsis Schiller: flowering in spring and summer.
(2) Phalaenopsis mansoni, also known as Phalaenopsis Banna, blooms from March to April.
(3) Phalaenopsis philippinarum: flowering from May to June. Management of flowering period of Phalaenopsis: 1. Management before and after flowering: after the formation of flower bud of Phalaenopsis, more phosphorus should be applied until flowering. When the flower stem is pulled out upward and inclines to one side, it is necessary to erect a pillar to bind it so as not to break the pedicel. After that, the pedicel grows and grows gradually, and the binding should be carried out gradually, with the pillar slightly arcing to enhance the aesthetic feeling. Stop applying fertilizer before flowering and new leaves grow. For the strong orchid plants with more than 5 leaves after flowering, 3-4 nodes of the lower part of the stem can be left, and it is expected to bloom again on the remaining flower stems in the future. Watering should not be too frequent, and watering should be done after it is dry.
2. Phalaenopsis flowering period to strictly control the temperature: not too high or too low. The optimum temperature is 15 ℃ to 18 ℃ at night and 23 ℃ to 25 ℃ at daytime. The continuous low temperature below 14 ℃ can lead to the growth retardation of flower buds, even sepals frostbite, abnormal development of flowers and complete loss of ornamental value. If the temperature is too high (above 20 ℃ at night and above 27 ℃ at night), the metabolism will be accelerated and the flowering period will be greatly reduced.
3. The intensity of light needed in flowering stage is very different from that in early stage: it needs to be cool and shaded in early stage, and the shade must be removed at this stage. The strong intensity of light is helpful for the flower to stretch, the internodes of flower arrow are even, and the flower color is gorgeous. In this case, there is no need to enhance the light intensity and follow a fixed accurate light intensity data.
