1, temperature
The low temperature in winter is very unfavorable for orchid conservation. When we maintain orchids in winter, we need to move them indoors as soon as possible and put them in a ventilated and cool place for maintenance. It is best to ensure that the temperature of the conservation environment is about 15 degrees, so as to ensure that they will not be frozen and ensure their growth in the coming year.
2. Land
During the growth of orchids, almost all nutrients are absorbed from the soil, so only by choosing suitable soil for maintenance can they grow. Orchids are suitable to grow in acidic soil, so we should pay attention to this point when configuring and maintaining the soil, and control the ph value between 6 and 7, so that acidic soil can give orchids more nutrients and help orchids grow vigorously and bloom as soon as possible.
3. Lighting equipment
Orchids are shade-loving plants, so they can't receive more light, otherwise it will cause yellow leaves to burn. Therefore, attention should be paid to shading measures during maintenance, and a little light should be received in winter and early spring to promote orchids to grow more vigorously. In summer, attention should be paid to maintaining it completely in a cool and ventilated place.
water
Orchids only need to keep the soil slightly moist during the maintenance period, because excessive watering will cause water accumulation in the roots, and finally the orchids will rot. The frequency of watering orchids in winter can be controlled at about 7 days, which may lead to freezing injury. We'd better water them with warm water.
Extended data:
Orchid is a plant that likes warmth and is afraid of cold. Most orchids in China are distributed in tropical and subtropical regions, only a few species (Cymbidium hybridum and Cymbidium hybridum) are produced in temperate regions, and orchids in the north of the Yellow River basin with higher latitude are less distributed. It can be seen that orchids need to live in a certain temperature range to grow and develop normally.
In the hot summer, when the outside temperature is higher than 38℃, the temperature will not exceed 30℃ in the daytime because of the good shade in the deep forest where orchids grow.
When the temperature is lower than 0℃ in cold winter, the ground temperature will not be lower than 0℃ because orchids are covered with fallen leaves and snow, so the adaptive temperature of orchids is between 0℃ and 30℃. Generally speaking, orchids grow slowly above 30℃, and seedlings below 0℃ will suffer from freezing injury.
Different varieties of orchids have different requirements for temperature. Cymbidium hybridum and Cymbidium hybridum, which are relatively distributed in northern China, have the strongest cold tolerance because they grow in places with higher latitude, higher altitude and lower temperature and adapt to the local cold winter climate for a long time, such as the south.
It is difficult to blossom because of insufficient vernalization.
However, Cymbidium hybridum and Cymbidium hybridum, which are relatively distributed in the south, are difficult to grow and bloom in the north because they grow in places with low latitude, low altitude and high temperature.
