China's lowest temperature season, nothing more than the winter solstice to the cold period, people used to call it midwinter. When it comes to winter, we can't forget the Vernalization of orchids. Some flower friends may not understand what is Chunhua, now let's go to understand what is Chunhua and Chunhua precautions!
Matters needing attention in Chunhua of Guolan
What is Vernalization of Cymbidium: Vernalization of Cymbidium refers to the low temperature stage that must be experienced during the reproductive growth of Cymbidium, which plays an indispensable role in promoting the growth of flower buds. The degree of vernalization is related to the quality of orchid flowering, which can not be ignored.
Orchid Chunhua orchid Chunhua precautions: 1, Chunhua to be fully.
Generally speaking, the best vernalization period of orchid is from light snow to heavy cold, and the temperature in this period should be controlled from 0 ° C to 12 ° C. Generally, vernalization time should not be less than one month, especially from winter solstice to severe cold.
2. Avoid too high or too low temperature during Vernalization.
During the vernalization stage, the temperature should not fluctuate too much. The low temperature below - 5 ° C and the temperature above 15 ° C are not conducive to the normal growth of flower buds. It is easy to cause the orchid buds stiff and affect the elongation of flower buds. The spring orchid often appears the phenomenon of "opening in spring", which greatly reduces the flower quality.
3. Avoid high humidity during Vernalization.
Orchid in nature, vernalization period is the lowest period of air humidity and soil humidity. The ecological environment of orchid in nature is the direction that orchid indoor industry must strive to create. Therefore, the air humidity and basin soil humidity in vernalization stage should not be too high, otherwise it is easy to rot buds and roots, which is not conducive to the growth of Cymbidium in the next year.
Practice has repeatedly proved that low temperature vernalization is an insurmountable stage of Cymbidium reproductive growth, and orchid breeders should not change it artificially against the natural law. In order to make orchids bloom better, orchids must be fully vernalized.
