What is the appropriate temperature for orchids?

The suitable temperature for the orchid is between 15 and 25 degrees, when the temperature around the orchid is lower than 5 degrees or higher than 30 degrees, its growth will enter a state of stagnation, and then slowly enter the dormant period.

In addition, when the orchid is propagating, it is necessary to keep its temperature at about 15 degrees, which is conducive to its seedling raising. The place where the orchid is placed is very important, and it directly affects the growth and development of the orchid.

Orchids are placed in the open field in spring, summer, and autumn (in the shade of the open field in the summer) and indoors in the winter. It is best to be open and humid outside, and there should be plenty of light indoors, preferably facing south. This is conducive to the growth of orchids, and the orchid pot is best placed on a wooden frame or table, not on the ground.

Potted orchids in the north should be moved indoors when the temperature drops to 5 o'clock before and after the frost festival, and the windows should be opened frequently at the beginning of the room to maintain air circulation. In winter, it is advisable to keep the room temperature at about 10. After Gu Yu, he moved to the outside for maintenance.

The suitable temperature for orchid growth is 16 24, and the indoor temperature in winter is generally low, 10 12 during the day and 5 10 at night, and the temperature and humidity can not be too high; Summer temperatures do not exceed 30.

Orchids like shade and moisture, if you want orchids to grow well, you need to give it a suitable growth temperature, generally the appropriate growth temperature is between 10-30 °C, orchids are not cold and high temperature resistant, when the ambient temperature is lower than 5 °C or more than 35 °C, there will be obvious slow growth, so pay attention to the temperature in the process of maintenance.

Orchid growth characteristicsOrchids like shade and are afraid of direct sunlight; Prefer moisture, avoid dryness; It likes to be fertile and rich in a lot of humus; A well-ventilated environment.

The most distributed species of orchids in BOC are in Yunnan, Sichuan and Taiwan Province. In addition to Ningxia, Qinghai and Xinjiang in the northern, northeastern, and northwest provinces, there are different species of orchids in all provinces and regions of China.

The most suitable growth temperature for orchids is usually between 10-30C, and when the ambient temperature is lower than 5C or more than 35C, the phenomenon of slow growth will obviously appear, and then it will show a tendency to enter a dormant state.

Is orchid resistant to high temperatureOrchids are not resistant to high temperatures, and it is easy to have problems in a high temperature and humidity environment, and the leaves are easy to turn yellow, appear black spots, and are prone to stem rot and soft rot, resulting in orchid disease and death.

How many degrees of minimum cold tolerance of orchids are different for different species of orchids, and the minimum cold tolerance of orchids is -4C; Chunlan is about the same as lotus petal orchid, about -2C; Jianlan is 2c; Melan can only withstand 5C.

What temperature can orchids be planted outdoors between 15-30 can be planted orchids, in late winter and early spring when the temperature has just stepped above 15, at this time the temperature is unstable, new orchids should pay attention to prevent spring cold, to prevent the temperature is too low orchids from freezing.

Orchid growth processOrchids begin to grow during the spring period, and during the spring, when the ambient temperature stabilizes above 15 degrees, the orchid will gradually sprout and begin to grow. When the temperature is above 20 degrees, the buds and leaves of the orchid will continue to grow, the speed will become faster, the root system will be obvious, the leaves will become longer, the color will be green, and bright flowers will bloom in the later stage.

Orchid Cultivation MethodThere are two ways to grow orchids. The first is the sowing method. Choose a relatively tall pot with drainage holes, and fill it with loose, breathable and nutritious soil, soak the seeds in sodium chlorate solution for seven or eight minutes, then clean and dry, sprinkle on the surface of the potting soil, and then cover with a thin layer of soil.

The second is the dividing method, after the mother plant is depotted and the old soil is removed, the dividing point is found and cut with scissors, and then the wound is disinfected and planted separately.

The optimal temperature is 25-30 degrees Celsius and the optimal humidity is around 60-80.

Orchids love warmth, and the higher the temperature, the more fragrant the flowers it will produce. Generally speaking, the temperature is above 30, and under sufficient sunlight, the flowers will be fragrant; On the other hand, if you are in a shade with insufficient light in the environment below 30, the flowers that bloom will not be as fragrant as they are when the temperature is high. To raise Milanese flowers, the temperature is between 20 and 35.

The best temperature suitable for orchid growth is 15 -25, the temperature is higher than 30 will grow slowly or stop growing, orchids grow well when the relative humidity of the air is 60-70%, too dry or too wet are easy to cause orchid disease;

The humidity requirement is not less than 70% during the summer growth period, and the humidity requirement of orchids has a certain regularity, the humidity demand increases during the growing period, the humidity demand decreases during the dormant period, the humidity demand increases during the day, and the humidity demand decreases at night.

Orchids can only grow within a certain temperature range, and the influence of temperature on the growth of orchids is comprehensive, which can affect the growth of orchids by affecting metabolic processes such as photosynthesis, respiration, and transpiration, as well as by affecting metabolic processes such as the synthesis and transportation of organic matter.

The most suitable growth temperature for orchids is 15-25, and when it enters the breeding period, the temperature needs to be controlled at about 15, which is conducive to the cultivation of plants.

The orchid temperature is between 20 and 30.

Orchid is a ground-born herbaceous plant, growing in the shade, ventilation, no waterlogged hillside, like a warm and humid environment, suitable for orchid growth between 20 and 30 temperature, the best growth temperature is about 26 to 28, pay attention to shading and cooling in summer, and pay attention to warmth and frost protection in winter.

Raising orchids to avoid over-drying and over-humidity, watering should be based on planting, ventilation and weather and other conditions to flexibly master the number of watering, the general principle is to keep the pot moist but not wet or slightly moist state, can not let the pot accumulate water or in a state of high water content for a long time, which is easy to lead to the root breathing obstruction and rot root rot seedlings.

Orchid maintenance

1. Sufficient light

Although orchids like shade, sunlight is the energy factor of long-leaf pregnant buds and is a prerequisite for flower bud germination. This is the truth of what Gu Lan said in his writings: "If there is more yang, the flower is better".

2. Proper water control

The growth of orchids is divided into two links, namely vegetative growth and reproductive growth, vegetative growth refers to the process of increasing the number of leaves, elongation and widening of leaf shape, and this process requires a large amount of water; Reproductive growth refers to the process of germinating flower buds, flowering and fruiting, and this process requires less water, especially when flower buds are conceived and petals bloom, water must be controlled.

3. Reasonable fertilization

The flowering of bluegrass mainly depends on nutrients such as phosphorus, hydrogen, oxygen and nitride stored in the pseudobulb, so the application of phosphorus and potassium fertilizers has become a necessary means to promote flowering.

Suitable temperature for orchids: 15-25.

The most suitable growth temperature of orchid is 15-25, when it enters the noisy beam into the finger bend and reproduction is delayed, the temperature needs to be controlled at about 15, which is conducive to the seedling cultivation of plants. Generally speaking, when the temperature is above 30, the orchid grows slowly or stops growing, when the temperature is between 0-15, the orchid enters a semi-dormant state, and when the temperature is below zero, the orchid stops growing.

The effect of suitable temperature on the growth of orchids

1. Promote the growth of orchids

Temperature affects the metabolic processes such as photosynthesis, respiration and transpiration of plants, as well as the absorption and conduction of water and fertilizer by plants, which together will affect the normal growth of plants. Therefore, orchids can grow well in the right temperature range.

2. Promote the absorption of nutrients

At temperatures between 20 and 30, fertilizing orchids is the most suitable. Fertilization at this time is conducive to the absorption of nutrients by the plant and promotes the rapid growth of leaves. If the temperature is too high or too low, it will affect the volatilization and photosynthesis effect of fertilizer, which is not conducive to the synthesis of nutrients.

Precautions

When cultivating orchids, it is necessary to take protective measures against temperature. When it is hot in summer, it is necessary to cool down and humidify in time, and the plants can be cultivated in a semi-cool place and sprayed with water mist all around. When it is cold in winter, it is necessary to do a good job of insulation.
