Skillfully use temperature difference to raise orchids three times a year. Autumn seedlings have become a big grass in winter.
Temperature difference of orchid
Winter is the most obvious temperature difference between day and night. Orchid farmers should seize the opportunity to use the temperature difference to cultivate orchids and strive to raise orchids better. In winter, the outdoor temperature in most parts of China is generally below 10 degrees, the vegetative growth of orchids is over, but the reproductive growth is slow.
In the long-term process of natural evolution, in order to blossom and bear fruit in the coming year, orchids keep pace with the times and constantly adapt to climate changes, forming the characteristics of low temperature vernalization in winter. Practice has repeatedly proved that full vernalization is a necessary stage for orchids to bloom at the right time, and we can't go against the laws of nature. Therefore, the room temperature of orchids with flower buds can not be too high in winter, generally not more than 15 degrees during the day, and the temperature difference between day and night should be large, as long as the temperature is not lower than zero at night. Otherwise, contrary to one's wishes, orchids often do not bloom in buds, and even if they bloom, the flowers are greatly reduced.

Orchids without buds can be warmed appropriately, and temperature differences are skillfully used to promote their growth. Closed balconies and rooms with plenty of heating and sunshine in the north in winter, the temperature can reach about 20-25 degrees during the day in sunny weather, such as ensuring that the humidity is above 40%. Very conducive to the growth of orchids. I know an orchid friend who installs a water temperature radiator on a closed balcony, heats and humidifies during the day, turns off the radiator at night, the temperature difference between day and night can reach about 15 degrees, orchids thrive, autumn buds can grow into big grass in winter, and the master has achieved the record of sprouting three times a year and growing into strong grass, which is surprising.
