What is the minimum temperature that an orchid can accept?

The minimum temperature is 10 degrees, and it is generally difficult for orchids to grow below 10 degrees, and above 10 degrees Celsius there is no effect.

The most moderate temperature of orchids in the greenhouse is 5 ° 15 °, the temperature difference between day and night is 10 ° is ideal, the daytime temperature is not lower than 10 °, and the night temperature is not lower than 5 °, which is very important for the growth and development of orchids.

For example, in the long-term low temperature and high humidity environment of orchids in winter, it will affect the respiration of orchid plants and cause root rot. When the temperature drops below 0 degrees, it is necessary to take measures to keep warm.

15 degrees Celsius, it is best to plant orchids at about 18 degrees Celsius, but the minimum should not be lower than 15 degrees Celsius, the temperature is too low, which will make the orchid grow slowly, or even stop growing.

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.

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 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 hardiness of orchids varies according to their species, but the most cold-tolerant are the cymbidium and spring orchid, which can withstand temperatures as low as -2 degrees Celsius.

Orchid flowers in the cool mountains and valleys, gradually developed the habit of liking wind and cooling, the best temperature suitable for orchid growth is 15 -25, in this cool environment orchid can grow rapidly, when the temperature is lower than 15, the orchid will gradually stop growing, into the "semi-dormant" state, the temperature is higher than 30 when the orchid will gradually stop growing, into the "semi-dormant" state.

Orchids like fresh air, which is a common feature of all plants, and orchids like it, and the air is very humid. Afraid of dryness, the optimal air relative humidity is 70 85%, Jianlan, Hanlan can be slightly dry, Molan Chunlan can be slightly humid.

It can tolerate low temperatures as low as -10 degrees Celsius.

1. The cold-tolerant temperature of most orchids is about 5, and some orchid varieties with good cold tolerance, especially wild orchid varieties, can tolerate a short period of -5 low temperature.

2. The cold-resistant temperature of orchids is a limit condition, and normal maintenance is generally carried out indoors in time when the temperature is at 10 to keep warm and control the temperature to avoid frostbite of orchids.

3. The two Guangxi areas can be wintered outdoors, but the draft wheel beam needs to be bagged in time to keep out the cold in cold weather.

Introduction to Orchids:

1. Orchid (scientific name: cymbidium ssp）：

It is a common name for monocots, orchids, and orchids. Epiphytic or terrestrial herbs, leaves several to many, usually born at the base of the pseudobulb or on the lower nodes, in two rows, banded or rarely inverted-lanceolate to narrowly elliptic, the base is generally broadly sheathed and encloses the pseudobulb, and the nodes are related.

2. The racemes have several or multiple flowers, and the colors are white, pure white, white-green, yellow-green, light yellow, light yellow-brown, yellow, red, blue, and purple.

3. The orchid in the traditional Chinese famous flower only refers to a number of tung sap native orchids distributed in the Chinese orchid genus, such as Chunlan, Huilan, Jianlan, Molan and Hanlan, etc., which is usually referred to as "Chinese orchid".

4. This kind of orchid is very different from the tropical orchid with large and colorful flowers, no eye-catching showy, no huge flowers and leaves, but it has a simple and quiet, elegant and noble temperament, which is very in line with the aesthetic standards of Oriental people. It has been cultivated in China for more than 1,000 years.

5. Chinese have always regarded orchids as a symbol of nobility and elegance, and are collectively called "four gentlemen" alongside "plum, bamboo, and chrysanthemum". Usually "Lan Zhang" is used to metaphor the beauty of poetry and literature, and "Lan Jiao" is used to metaphor the truth of friendship. There are also orchids to express pure love, "the breath is like an orchid that does not change, and the heart is like an orchid that will never change", "find a confidant in Youlan, and talk about a dream of Xiaoxiang".

In May, the orchid was rated as the fourth of the top ten famous flowers in China.

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.
