What are the requirements for air humidity for orchids

The importance of air humidity in the cultivation of orchids.

The optimal growth temperature of orchids is 15-25, and it needs to be kept at about 15 in the breeding period to facilitate the cultivation of seedlings. Generally speaking, when the temperature exceeds 30, the orchid will grow slowly or stop growing, and in the morning of 0-15, the orchid will enter a semi-dormant state, and the temperature will stop growing when the temperature is below zero. Therefore, the temperature of orchids should be controlled, and the appropriate temperature can promote the growth of orchids and the absorption of nutrients.

Orchids prefer a cold environment, the general temperature is about 15 degrees to 30 degrees, all orchids are long-term, you can raise orchids. When the indoor temperature is relatively constant, the danger of raising orchids is less. But if you raise orchids outdoors, you must pay attention to the stability of the temperature.

What temperature is the orchid suitable for.

Suitable for orchidsThe growing temperature is between 20-30, preferably around 26-28In summer, we should pay attention to shading and cooling, and in winter, we should pay attention to keeping warm and anti-freezing, and orchids and ground-planted orchids have different requirements for low temperatures.

1. Winter temperature control

Some ground-grown orchids can withstand low temperatures above minus 10, because the ground temperature is warm and the leaves are warmed and then adjusted; Potted orchids lack the above factors, and when the temperature is about to drop below 0, they should be transferred to an environment with a temperature of more than 3-5 in advance to avoid freezing water in the orchid plant and causing frost damage.

2. Summer escape

In summer, it is necessary to find a way to control the temperature of the orchid placement within 32, and if it exceeds 35, it is necessary to force the temperature to be cooled, in addition, the orchid is also easy to get sick.

If the temperature cannot be controlled within 32, it is necessary to strengthen ventilation to reduce the probability of disease, good ventilation can accelerate the evaporation of water in the basin and reduce the number of harmful bacteria.

What humidity orchids are suitable for.

The humidity suitable for orchid growth is between 40-80%, and the optimal humidity is between 50-70%.。Generally, the humidity of more than 80% is also prone to high temperature and high humidity environment, so the humidity of less than 40% of the orchid will be decentralized, water stiffened, or even shrunk.

When maintaining orchids, we should avoid drying out and getting too wet, and water them according to the planting materials, ventilation, weather, etc., and flexibly control the number of waterings.

The general principle is to keep the potting soil moist, not damp, and slightly moist, and do not let the pelvic cavity accumulate water or be in a state of high moisture content for a long time, which can easily lead to panting and rotting root rot seedlings.

Effect of temperature on orchid growth.

1. Promote the growth of orchids

The photosynthesis of plants is affected by temperature, such as respiration, transpiration, and water metabolism processes, which also affect the absorption and conduction of water and nutrients by plants, thus affecting the normal growth of plants. As a result, orchids can grow well in the right temperature range.

2. Promote the absorption of nutrients

In the temperature range of 20-30, orchids are most suitable for fertilization. Fertilization at this time is conducive to the absorption of nutrients by the plants and the rapid growth of leaves. If the temperature is too high or too low, it will affect the volatilization of fertilizers, affect the photosynthetic efficiency, and affect the synthesis of nutrients.

1.The suitable temperature for the growth of orchid flowers is between 15-25, and there is no need to worry when the temperature of breeding has a small fluctuation, but the fluctuation should not be too large.

2.It is not a hardy plant, so the minimum temperature should also be kept at around 10, and if the temperature is too low in winter, it will suffer from wind chill and frostbite.

3.In addition, it is necessary to pay special attention to the summer, and when the temperature rises significantly, it is necessary to cool down.

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.

The temperature is not lower than 7 -8. Most of them can be cultivated in the open air. Jiangsu and Zhejiang are accustomed to move the Jianlan, Hanlan and Primrose orchids that require slightly higher temperatures into the indoor cultivation after the "beginning of winter", and move some spring orchids and Huilan with flower buds under the eaves or in a place to avoid the cold, so as to avoid the invasion of the first frost and affect the development of flower buds.

When the ground orchid winters indoors, the key is to master the temperature and humidity. Generally, the room temperature should be kept above 7 -8, and the ideal should be kept at 10-15. After entering the room, if the weather has not yet been cold and frozen, the south window should be opened around noon, and the small air window should be opened on the north side to facilitate indoor air circulation.

In the evening, if the indoor temperature is still above 5, the small air window between the north and south can be slightly opened; If it is less than 5, all windows should be closed. In the middle of winter, only at noon on a windless and sunny day, the window is slightly half opened, slightly breathable, and the doors and windows should be closed when the sun is slightly deviated, and the straw curtain or cotton curtain is hung at night. If the temperature continues to drop below 3 -5, it can be heated by a coal furnace with a chimney tube.

You can use "Yanwo microbial agent" + "root rooting agent" in the early stage, and the effect will be better when combined with Yanwo water-soluble fertilizer.

Breeding orchids have special requirements for temperature, because orchids are very delicate and passive, so the temperature must be kept at about 20 25 degrees, if the temperature is particularly high, orchids are particularly easy to be sunburned, and if the temperature is particularly low, orchids may be frostbitten.

No, orchids are actually not afraid of the cold, and orchids can still be lush in winter when they move indoors, and the most suitable temperature for orchid growth is 25, and the orchid flowering period is longer within this temperature.

There are special requirements, the requirement is that the temperature must be controlled at about 15 24, and the orchids also need to be cultivated in a sunny place.

The temperature must be controlled below 25, and the most suitable temperature should be around 8 15.

Orchids grow fastest at 15-25 degrees, and the humidity is best at around 70%, however, orchids also need to be dormant during the growth process, requiring low and high temperatures, and large temperature differences.

Therefore, if it is kept at a certain temperature for many years, it may grow quickly, but it will not be very good, and its flower buds will not differentiate easily.
