In summer, orchids learn to blossom with air conditioners.

The hot temperature and dry air in summer have a serious impact on the growth and development of orchids. The most suitable temperature for orchid growth in summer is between 25 and 28 ℃. The highest temperature in the afternoon in summer can reach more than 40 ℃, which is not conducive to the growth of orchids, and even causes orchids to stop breathing and photosynthesis, dormancy and stop growing because of high temperature.

In order to adjust the temperature, flower friends use electric fans to strengthen ventilation and spray water around the orchid frame to cool down. Although there are some effects, it is difficult to reduce the temperature of the orchid environment to the most suitable temperature for orchid growth. The air conditioner can accurately adjust the temperature in the orchid room, and blowing air conditioning to the orchid in summer can be said to be a good way to cool down. But to the orchid air conditioner, want to blossom, but also a certain fastidious.

Some flower friends think that they use air conditioners during the day, cool down at night, and stop using air conditioners at night. This understanding is wrong. Because the temperature is still about 30 ℃ for most of the night in summer, the absence of a large temperature difference is not conducive to the growth of orchids.

Some flower friends do not use air conditioning during the day, use air conditioning at night, so that the temperature drops suddenly at night, the purpose is to increase the temperature difference between day and night, so that orchids store nutrients, which is also a misunderstanding.

Because the orchid does not use air conditioning during the day, the high temperature will make the orchid in a semi-dormant state, hinder the photosynthesis of the orchid, unable to absorb and synthesize enough nutrients for growth, and suddenly cool down at night. If the temperature difference between day and night is more than 10 ℃, the respiratory function of the orchid is not normal, and it is not conducive to the growth and development of the orchid.

In summer, in order to prevent the damage to orchids caused by high temperature during the day. The correct use method of cooling with air conditioner should be: generally, when the temperature exceeds 28 ℃ in the afternoon, the ambient temperature can be adjusted to 26-28 ℃, which is suitable for orchid growth. This can promote the photosynthesis of orchids, regulate the respiratory function of orchids, and make them grow and develop normally.

At night, orchids enter the dark cycle and release the energy stored in the body during the day through breathing to maintain normal metabolism and nutrient accumulation, so as to better promote the growth and development of orchids. The temperature difference between night and daytime should be kept at about 10 ℃, which is the most suitable for orchid growth.

In addition, the cooling effect of indoor air conditioning is good, but the humidity is low, so it is necessary to adjust the air humidity and pay attention to sprinkling water with spray kettles; we should also pay attention to strengthening light supplement, for without sufficient photosynthesis, the growth of orchids will still be restricted.

In addition, in summer, some orchids have not yet entered a dormant state, when flower friends need to replenish the orchids. It is generally recommended to use orchid special organic liquid fertilizer, water and fertilizer in summer high temperature, combined with watering, good absorption, not burning roots, can not only supplement water, but also increase nutrients and promote the growth of orchids.
