You Lan Xiao Chen complained: I finally fed a pot of Chunlan, and it got pregnant and vernalized successfully. After the Spring Festival, it blossomed. I thought it was a positive result, but this Chunlan has no fragrance at all. Why?
In fact, whether the flowering of Cymbidium hybridum has fragrance or not has the greatest relationship with light except orchid species. A few days before the Spring Festival, a group of cymbidium flowers that farmers can easily photograph blossomed. These are the pictures in the picture. I remember years ago (the 27th day of the twelfth lunar month-the second day of the first lunar month), the sun was shining, and the orchids of the farmers were basking in the sun every day. People passing by my door will say from a distance: this orchid is really fragrant.
But since the third day of the first month, the sun has not been seen for half a month, and orchids have not smelled the fragrance. Yesterday (February 20), farmers saw the sun coming out of the window and quickly moved the orchids out to bask in the sun. Although it only lasted for ten minutes, it was amazing that it took the sun 65,438+00 minutes to make the orchids bloom all day.
Why does sunshine have so much to do with the fragrance of orchids? Farmers can easily find some rules through the flowering characteristics of other plants.
What do plants bloom for? The answer is simple, not to please human beings, but for their own reproduction.
Then they need pollination when they bloom, because there is little pollen, and the best time for pollination is sunny morning, because many pollinators are active at that time. Therefore, flowers must open at that time to complete pollination.
The fragrance of orchids (including other flowers) can only be smelled when the male and female styles are open. In other words, their fragrance is actually to attract pollinators. So this series can be linked: sunny days-open styles-fragrance-insect flying-pollination-breeding species.
The Chunlan of the orchid friend above just blooms in the first month, and the geographical coordinate is Hangzhou. The climate is basically the same as that of farmers' hometown, and it rains every day. His orchid has never seen the sun since it bloomed. It is normal that such orchids have no fragrance, and no one can help him.
Another case is that after Chunlan was completely vernalized, You Lan moved into an office, tea room and other environment with insufficient light. Due to the lack of light for a long time, this orchid will only have a little fragrance when it first blooms, and it will basically not smell the fragrance the next day. This situation is very simple to deal with, that is, when there is sunshine, take it out to bask in the sun, and the orchid can re-emit its fragrance in just one day.
Not only Chunlan, but also orchids. If you are short of light for a long time, not only will the fragrance be less, but the flowers will be as weak as frost, which will affect the opening of orchids.
If you find that your orchid is not fragrant, the first thing to check is whether there is suitable light in the environment. Give orchids as much sunshine as possible during flowering, which will not only make the flowers more fragrant, but also allow orchids to accumulate more nutrition, which is also of great benefit to new seedlings after flowering.
