A brief discussion on "Lan Hui to spend the Winter" (vernalization)

Vernalization in the depths of winter

Press: you will be slapped at the mention of vernalization, and it is also right to think about it: to describe the ecology of orchids with botanical concepts is not only copied mechanically, but also suspected of embezzling the concept. In any case, orchids still have to get through this extraordinary period, so let's change this vernalization to winter first.

Every year, the period from the Winter Solstice to Greater Cold is the season with the lowest temperature in all parts of China, which is traditionally called the depths of winter. When it comes to Yilan in the depths of winter, we must not forget Lan Hui's problem of spending the winter.

The so-called winter refers to the low temperature stage that Lanhui must go through during the period of reproductive growth, which can not be replaced by other natural and artificial conditions in promoting the expansion and growth of flower buds. The degree of wintering has a direct impact on the quality of Lanhui's products, which should not be taken lightly. There are several problems that should be paid attention to in the depths of winter: first, we should make full use of the winter. Generally speaking, the period from Lesser Snow to Greater Cold is the best winter period for Lan Hui. the temperature in this period had better be controlled at 12 °, and the winter time should not be less than one month, especially from the Winter Solstice to Greater Cold. Second, the temperature should not be too high or too low during the winter. During the winter period, the temperature must not fluctuate too much. The low temperature below-5 °and the temperature higher than 15 °are not conducive to the normal growth of flower buds, which can easily lead to stiff buds and affect the uplift of scape. Chunlan often appears the phenomenon of spring blooming, which greatly discounts the flowers. Third, avoid excessive humidity in winter. The wintering period is the lowest period of air humidity and soil moisture of orchids in nature. The ecological environment of orchids in nature is the direction of our indoor orchid cultivation. Therefore, the air humidity and basin soil humidity in the winter stage should not be too high, otherwise it is easy to rot buds and roots, which is not conducive to the growth of Lan Hui in the coming year. Practice has repeatedly proved that low temperature winter is an insurmountable stage of Orchid reproductive growth, we can not violate the laws of nature and artificially change it, otherwise, it is bound to go against our wishes and directly affect the opening of orchids. In order to make the orchid flowers bloom better, let's let the orchids survive the winter boldly.

Although studies have shown that water control, drugs and other methods can be used to replace the winter, but the natural winter conditions are the most effective. Of course, in the south, north and other natural conditions can not meet the requirements of the winter can also be used artificial methods. It is best according to the requirements of Lan Hui, natural and artificial conditions together, will certainly achieve twice the result with half the effort. (less watering, window ventilation when the sun shines during the day to prevent bluegrass from getting out of dormancy when the temperature is too high. )

I also feel awkward after changing vernalization to winter this time, but in order to respect science, get used to it!
