The best climate environment for Chinese orchid growth

Any plant can survive and grow under certain climatic conditions, and the climatic conditions for all kinds of plants to survive and grow are different. The best climatic conditions for the growth of national orchids are as follows:

(1) temperature. Cymbidium, Jianlan 25 ℃ 30 ℃; Cymbidium, Cymbidium. Hanlan 18-24 ℃.

(2) light. Sunny workers shade 75% in summer and autumn, 50% sunny in winter and spring, and UV index above 5 will burn leaves. Jianlan and Hanlan prefer Yang, while other orchids prefer Yin. However, if there is no small amount of sunlight, the flowering rate and budding rate of all orchids are low.

(3) the relative humidity of the air is 80% 100%.

(4) the absolute soil humidity is 80% 100%.

(5) the temperature difference between day and night is 6 ℃ 12 min. That is, it is best to be warm in the day and cool at night.

(6) Wind force. Southeast wind 1 MUE level 2.

Because the original growth environment and growth habits of all kinds of orchids are slightly different, the best climate conditions for their growth are also slightly different.

Cymbidium was originally grown in the south of 26 degrees north latitude (lower latitudes at higher elevations and higher latitudes at lower elevations). For example, in southern Fujian, it also grows at some lower elevations at 27 degrees north latitude. Therefore, Cymbidium prefers higher temperature, and it is still better to grow at 30 ℃. On the other hand, it has a lower requirement for light and does not need too strong light. Jianlan, such as Daqing orchid, like strong light, the burn in direct sunlight is not as serious as ink orchid, and some balconies can be placed for a long time to grow well. Cold orchids generally grow at higher elevations and are more resistant to high cold, and cold orchids grow at 32 degrees north latitude. Cymbidium grows at an altitude of more than 400m to 1000 m above sea level, and also grows at 32 degrees north latitude, so it is also hardy. Chunlan and Hanlan both like the big temperature difference between day and night, and they also need strong light. Mulan is most afraid of strong light, affected by direct sunlight, the leaves will be burned in a few hours, scorched patches will appear a few days later, and can not recover. If the leaves of all kinds of orchids temporarily turn yellow due to lack of water and poor ventilation, once the climatic conditions are good, they can slowly return to green and continue to grow, don't worry.
