I also compared the orchid service pots in different seasons, such as autumn, early winter and spring. With the same planting method, new crystal heads can be seen in more than 20 days in spring, more than 40 days in autumn, and even new crystal heads will not germinate in early winter. In this case, the problems of planting materials and planting methods can be ruled out, just because of the natural performance of plant growth laws in different seasons.
Of course, what I said above is that in the open air, the growth law of plants is in line with the natural environment. The orchid friend I mentioned at the beginning of the article is planted in a protected environment, and the temperature and humidity are not lost in spring. Arguably, in such an environment, orchids should have new roots and buds and crystal heads in a month.
Some orchids have been planted, some are planted in the open air, and the other will enter the orchid shed in a week. Around New Year's Day, I looked at these orchids separately and found differences. The orchids placed in the orchid shed have given birth to new roots, while the orchids placed outdoors remain unchanged.
This is the illusion that the orchid shed environment gives it a spring. At the same time, the temperature and humidity are relatively high, and orchids take root and sprout like spring. Outdoor orchids, however, have been carrying the information of autumn from the beginning of planting, and soon entered winter, and their growth information was suppressed.
If orchids in the natural environment grow regardless of seasons, what awaits them will be the destruction of species by freezing injury. Therefore, there is a kind of self-protection in the growth information of orchids, which is to avoid species destruction caused by improper seasonal growth.
Back to You Lan, what caused his orchids to grow new roots after 60 days of planting? As far as I can judge, there are two reasons.
One is the seasonal factor. Although the planting and conservation environment has certain protective measures, it may not meet the standard of "false spring", so the growth information of orchids is not stimulated, and naturally it will not take root and grow into crystals when it is in natural dormancy.
Followed by "soaking" (soaking sterilization drugs, fertilizers, etc. ) Over-planting caused orchids to be unable to bring pots. Simply put, the growth factor of orchids was killed in the process of soaking.
These are just my own views, which may be one-sided and limited, and are only for You Lan's reference.
